ABSTRACT

Introducción: El manejo inmediato del dolor postoperatorio es esencial para una comodidad y rehabilitación temprana del paciente Este estudio busca evaluar el efecto analgésico postoperatorio inmediato en cirugías de columna lumbosacra por vía posterior, como los efectos adversos con la administración de analgesia intratecal, usando Clonidina contra Morfina. Material y métodos: Es un estudio analítico de intervención, cuasi experimental, prospectivo, longitudinal, comparativo, doble ciego. Para comparar la eficacia de la analgesia intratecal post operatoria inmediata en cirugías de columna lumbosacra primarias por vía posterior y los efectos adversos. Los pacientes se distribuyeron en dos grupos previamente designados, a un grupo se le administro Clonidina 0.5 microgramos/kg/peso y a otro grupo Morfina 5 microgramos/Kg/Peso. intratecal, intraoperatorio. Resultados: Existió diferencia estadísticamente significativa con mejor manejo del dolor postoperatorio en las primeras horas y menor presencia de vómitos en el grupo de pacientes que se utilizó Clonidina intratecal. No existió diferencia estadísticamente significativa de ambas medicaciones intratecales en la valoración de otros efectos adversos. Discusión: El uso de la analgesia intratecal ha ido ganando relevancia en el tiempo y se fueron sumando estudios para ver la eficacia de diferentes medicamentos, diferentes dosis, menor presencia de efectos adversos. El estudio analiza estas variables buscando una mejor opción terapéutica. Tenemos a favor una muestra representativa a pesar de no ser aleatoria, estricto seguimiento, y análisis estadístico adecuado. Conclusión: La Clonidina intratecal es más efectiva para manejo del dolor post operatorio inmediato de cirugías de columna lumbosacra por vía posterior y con menor presencia de efectos adversos


Introduction: Immediate postoperative pain management is essential for the patient's greater comfort and early rehabilitation. Te goal of this study is to evaluate the immediate analgesic postoperative effect in posterior lumbosacral spine surgery, as well as the adverse effects of the administration of intrathecal analgesia, using Clonidine versus Morphine. Material and methods: An analytical, quasi-experimental, prospective, longitudinal, comparative, double-blinded intervention study was conducted to compare the efficacy of immediate postoperative intrathecal analgesia in primary posterior lumbosacral spine surgery, and the adverse effects. Te patients were divided into two previously designated groups. One group received Clonidine 0.5 microgramos/kg and the other group received Morphine 5 microgramos/kg. Intrathecal, intraoperative. Results: Tere was a statistically significant difference with better postoperative pain management in the first hours and less vomiting in the group of patients who received intrathecal Clonidine. Tere was no statistically significant difference between both intrathecal medications in the evaluation of other adverse effects. Discussion: Te use of intrathecal analgesia, has been on the rise over time and more studies have been conducted to see the efficacy of different drugs, different doses, with fewer adverse effects. Tis study to analyze these variables with a view to finding a better therapeutic option. Te advantage is having a representative if not random sample, strict follow-up, and appropriate statistical analysis Conclusion: Intrathecal Clonidine proved to be more effective in immediate postoperative pain management after posterior lumbosacral spine surgery and with fewer adverse effects

ABSTRACT

Abstract Regarding the proven anticonvulsant effect of Zhumeria majdae essential oil (ZMEO) in previous studies we were prompted to investigate the ZMEO effects on the tolerance to the anticonvulsant effects of morphine and the morphine withdrawal syndrome. Tolerance to the morphine anticonvulsant effect was induced in mice by subcutaneous injection of 2.5 mg/kg of morphine for 4 days. Subsequent doses of ZMEO (20 mg/kg) were used to study the expression and development of morphine tolerance. Clonidine was used as the standard drug to inhibit the morphine withdrawal syndrome symptoms. To study the ZMEO effect on withdrawal syndrome, mice received appropriate morphine values for 4 days and on the fifth day, 60 min before administration of naloxone. The effective dose of ZMEO was determined and the number of jumps, stands and changes in the dry stool weight, as symptoms of withdrawal syndrome were evaluated. The dose of 20 mg/kg of ZMEO decreased the tolerance in development and expression groups significantly. Counting the number of jumping, standing and defecation were assessed 30 min after morphine and 1 h after the vehicle and clonidine. The dose of 40 mg/kg ZMEO decreased all the signs of withdrawal syndrome significantly. ZMEO was analyzed by GC/MS and linalool (53.1%) and camphor (23.8%) were characterized as the main components. The results suggest that ZMEO possesses constituent(s) that have activity against tolerance to the anticonvulsant effects of morphine and the morphine withdrawal symptoms.


Resumo Em relação ao efeito anticonvulsivante comprovado do óleo essencial de Zhumeria majdae (ZMEO) em estudos anteriores, fomos instigados a investigar os efeitos do ZMEO em relação à tolerância aos efeitos anticonvulsivantes da morfina e da síndrome de abstinência de morfina. A tolerância ao efeito anticonvulsivante da morfina foi induzida em camundongos por injeção subcutânea de 2,5 mg/kg de morfina por 4 dias. Doses subsequentes de ZMEO (20 mg/kg) foram utilizadas para estudar a expressão e o desenvolvimento da tolerância à morfina. A clonidina foi usada como droga padrão para inibir os sintomas da síndrome de abstinência da morfina. Para estudar o efeito do ZMEO na síndrome de abstinência, os camundongos receberam valores apropriados de morfina por 4 dias e, no 5º dia, 60 minutos antes da administração de naloxona. A dose efetiva de ZMEO foi determinada, e o número de saltos e de permanência e as alterações no peso das fezes secas, conforme os sintomas da síndrome de abstinência, foram avaliados. A dose de 20 mg/kg de ZMEO diminuiu significativamente a tolerância nos grupos de desenvolvimento e expressão. A contagem do número de saltos, permanência e defecação foi avaliada 30 minutos após a morfina e 60 minutos após o veículo e a clonidina. A dose de 40 mg/kg de ZMEO diminuiu significativamente todos os sinais da síndrome de abstinência. O ZMEO foi analisado por GC/MS, e linalol (53,1%) e cânfora (23,8%) foram caracterizados como os principais componentes. Os resultados sugerem que o ZMEO apresenta constituintes que possuem atividade contra a tolerância aos efeitos anticonvulsivantes da morfina e aos sintomas de abstinência da morfina.

ABSTRACT

El paciente oncológico de cuidados paliativos puede presentar una variedad importante de condiciones clínicas que producen sufrimiento y disminución en la calidad de vida; esto se presenta como un reto para el clínico en la identificación y correcto abordaje de los pacientes. El dolor se ha considerado por años como el síntoma cardinal a tratar en el paciente oncológico, donde se deben considerar sus condicionantes fisiopatológicos, la farmacología de las intervenciones, los posibles efectos secundarios y los condicionantes familiares, sociales y personales del dolor, pero a pesar de su relevancia, no es el único síntoma, estando acompañado de un abanico de patologías, como las afectaciones gastrointestinales, pulmonares, vasculares, hematológicas y neurológicas, que favorecen la pérdida de capacidad del paciente y, en muchas ocasiones, la muerte. Se realizó una revisión actualizada en bases de datos como EMBASE, PUBMED, SCIELO, además de la revisión de guías de asociaciones internacionales con el objetivo de acercar a todos los médicos, sin distinguir su especialidad o área de trabajo, al abordaje y manejo del paciente oncológico en cuidado paliativo, favoreciendo la sensibilización con estas patologías y la importancia en el curso de vida de los pacientes.


The palliative care cancer patient can present a significant variety of clinical conditions that produce suffering and a decrease in the quality of life. This is a challenge for the clinician in the identification and correct approach of patients. Pain has been considered for years as the cardinal symptom to be treated in cancer patients, where its pathophysiological factors, the pharmacology of the interventions, possible side effects and the family, social and personal conditions of pain must be considered, but despite its relevance is not the onset of symptoms and is accompanied by a range of pathologies such as gastrointestinal, pulmonary, vascular, hematological and neurological affectations that favor the loss of capacity of the patient and in many cases death. An updated review was carried out in databases such as EMBASE, PUBMED, SCIELO in addition to the revision of guides from international associations with the aim of bringing all doctors without distinguishing their specialty or area of work to the approach and management of cancer patients in palliative care favoring awareness of these pathologies and their importance in the life course of patients.

ABSTRACT

The periaqueductal gray (PAG) is a complex mesencephalic structure involved in the integration and execution of active and passive self-protective behaviors against imminent threats, such as immobility or flight from a predator. PAG activity is also associated with the integration of responses against physical discomfort (e.g., anxiety, fear, pain, and disgust) which occurs prior an imminent attack, but also during withdrawal from drugs such as morphine and cocaine. The PAG sends and receives projections to and from other well-documented nuclei linked to the phenomenon of drug addiction including: (i) the ventral tegmental area; (ii) extended amygdala; (iii) medial prefrontal cortex; (iv) pontine nucleus; (v) bed nucleus of the stria terminalis; and (vi) hypothalamus. Preclinical models have suggested that the PAG contributes to the modulation of anxiety, fear, and nociception (all of which may produce physical discomfort) linked with chronic exposure to drugs of abuse. Withdrawal produced by the major pharmacological classes of drugs of abuse is mediated through actions that include participation of the PAG. In support of this, there is evidence of functional, pharmacological, molecular. And/or genetic alterations in the PAG during the impulsive/compulsive intake or withdrawal from a drug. Due to its small size, it is difficult to assess the anatomical participation of the PAG when using classical neuroimaging techniques, so its physiopathology in drug addiction has been underestimated and poorly documented. In this theoretical review, we discuss the involvement of the PAG in drug addiction mainly via its role as an integrator of responses to the physical discomfort associated with drug withdrawal.

ABSTRACT

ABSTRACT Background: As the number of bariatric operations increases, there is a greater interest in knowledge, experience and skills in the operative and anesthetic management of obese people. Anesthetic recovery is an important point in the therapeutic approach and less adverse effects delaying discharge of these patients are necessary to be kept in mind by the surgical team. Aim: To compare anesthetic-analgesic techniques in the opioid-sparing era through epidural administration of local anesthetic associated with low-dose morphine vs. clonidine and analyze the impact of analgesia on the effectiveness of postoperative recovery by comparing these two techniques. Methods: Randomized, double-blind clinical trial with 66 patients candidates for Roux-en-Y gastrojejunal bypass divided into two groups: morphine group and clonidine group. Multimodal analgesia included epidural anesthesia with 0.375% ropivacaine 20 ml at the eighth thoracic vertebra with the association of morphine (morphine group) at a dose of 15 mcg / kg or clonidine (clonidine group) at a dose of 1 mcg / kg. Results: The groups were homogeneous and statistical significance was found when analyzing the difference in pain between them in the first postoperative period. The pain was higher in the clonidine group, as in this period, analgesic rescue was also better in this group. In the other times, there was no significance in the differences regarding pain and rescue. The return of intestinal motility in the morphine group was earlier in the first postoperative period. Nausea, vomiting and hospital discharge did not show significant differences between groups. Conclusion: Epidural anesthesia with low-dose morphine allowed less pain during the entire hospital stay, with a positive impact on patient recovery.


RESUMO Racional: Com o aumento do número de operações bariátricas torna-se maior o interesse pelo conhecimento, experiência e habilidades no manejo operatório e anestésico de obesos. A recuperação anestésica é ponto importante na abordagem terapêutica e menos efeitos adversos que retardem a alta são necessários estar em mente da equipe cirúrgica. Objetivo: Comparar técnicas anestésico-analgésicas na era poupadora de opioides através da administração epidural de anestésico local associado à morfina em baixa dose vs. à clonidina e analisar o impacto da analgesia na efetividade da recuperação pós-operatória comparando as duas técnicas. Métodos: Ensaio clínico randomizado e duplo-cego com 66 pacientes candidatos ao bypass gastrojejunal em Y-de-Roux divididos em dois grupos: grupo morfina e grupo clonidina. A analgesia multimodal incluiu na anestesia epidural com ropivacaína 0,375% 20 ml na altura da oitava vértebra torácica a associação de morfina (grupo morfina) em dose de 15 mcg/kg ou de clonidina (grupo clonidina) na dose 1 mcg/kg. Resultados: Os grupos se mostraram homogêneos e foi encontrada significância estatística ao analisar a diferença da dor entre eles no primeiro pós operatório. A dor foi superior no grupo clonidina, como também neste período o resgate analgésico foi melhor neste grupo. Nos demais tempos não houve significância nas diferenças quanto à dor e resgate. O retorno da motilidade intestinal no grupo morfina foi mais precoce no primeiro pós-operatório. Náuseas, vômitos e a alta hospitalar não apresentaram diferenças significativas entre os grupos. Conclusão: A anestesia epidural com morfina em baixa dose permitiu menor dor durante todo internamento com impacto positivo em relação a recuperação dos pacientes.

ABSTRACT

OBJECTIVES: This study was designed to evaluate the clinical efficacy of controlled-release morphine tablets combined with celecoxib in relieving osteocarcinoma-related pain and the effects of the combination on WNK1 expression. METHODS: A total of 110 patients with osteocarcinoma-related pain were selected and divided into two groups based on the treatment administered, including the control group (treated with controlled-release morphine tablets alone) and the study group (treated with a combination of controlled-release morphine tablets and celecoxib). We compared the treatment efficacy, pain level (visual analog scale (VAS)), time of onset of breakthrough pain (BTP), dose of morphine, incidence of adverse events, quality of life (QOL) score, and With-no-lysine 1 (WNK1) expression in the peripheral blood (PB) as determined with qRT-PCR before and after treatment, of the two groups. RESULTS: The total effective rate of the study group was higher than that of the control group, while the VAS score, time of onset of BTP, dose of morphine, incidence of adverse events, QOL score, and relative WNK1 expression in the PB were lower than those of the control group (p<0.05). CONCLUSION: Combination treatment with controlled-release morphine tablets and celecoxib can be extensively used in the clinical setting because it effectively improves the symptoms, QOL score, and adverse effects in patients with osteocarcinoma-related pain.

ABSTRACT

Abstract Background and objectives There are no consensus of the ideal technique to provide analgesia in knee ligament reconstructions. The aim of this study was to compare the intensity of postoperative pain in these patients under different modalities of analgesia. Method Randomized and controlled clinical trial of patients undergoing reconstruction of the Anterior Cruciate Ligament (ACL) with flexor tendons between December 2013 and 2014. All patients underwent spinal anesthesia and rescue analgesia with tramadol. The groups C, M, R0,375 and R0,25 was compared with only the previously described technique, subarachnoid morphine (100░µg), or Femoral Nerve Block (BNF) with 25░mL of 0.375% ropivacaine and 0.25%, respectively. Pain intensity at 6, 12 and 24░hours, age, sex, rescue analgesia, adverse reactions and satisfaction were evaluated. Results Among the 83 eligible patients, a predominance of males (85.7%) was observed, between 28 and 31 years. The group C requested more opioid (27.3%) than the other groups, without significance when compared. There were no significant differences in pain intensity at 6, 12 and 24░hours. There was a higher incidence of urinary retention in the M group (23.8%) than in the R0,375 (0%) and prolonged quadriceps motor block in the R0,375 group (30%) than in the M and C groups (0%), with statistical significance (p░<░0.05). Conclusion There was no difference in the intensity of postoperative pain in patients submitted to ACL reconstruction with flexor tendons under the analgesic modalities evaluated, despite the predominance of urinary retention in the M group and motor block in the R0,375 group.


Resumo Justificativa e objetivos Não há consenso sobre qual é a técnica ideal para prover analgesia em reconstruções ligamentares de joelho. Objetivou‐se comparar a intensidade da dor pós‐operatória desses pacientes sob diferentes modalidades de analgesia. Método Ensaio clínico randomizado e controlado de pacientes submetidos à reconstrução do ligamento cruzado anterior com tendões flexores entre dezembro de 2013 e 2014. Todos os pacientes foram submetidos a raquianestesia e analgesia de resgate com tramadol. Compararam‐se os grupos C, M, R0,375 e R0,25; aos quais se ofertou apenas a técnica anteriormente descrita, morfina subaracnóidea (100 µg) ou bloqueio de nervo femoral com 25 mL de ropivacaína 0,375% e 0,25%, respectivamente. Avaliou‐se intensidade da dor em 6, 12 e 24 horas, idade, sexo, analgesia de resgate, reações adversas e satisfação. Resultados Entre os 83 pacientes elegíveis, observou‐se predomínio do sexo masculino (85,7%) entre 28 e 31 anos. O Grupo C solicitou mais opioide (27,3%) do que os demais grupos, sem significância quando comparados. Não houve diferenças significativas na intensidade da dor em 6, 12 e 24 horas. Houve maior incidência de retenção urinária no Grupo M (23,8%) do que no R0,375 (0%) e de bloqueio motor prolongado do quadríceps no Grupo R0,375 (30%) do que nos Grupos M e C (0%), com significância estatística (p< 0,05). Conclusão Não houve diferença na intensidade da dor pós‐operatória nos pacientes submetidos à reconstrução de ligamento cruzado anterior com tendões flexores sob as modalidades analgésicas avaliadas, apesar do predomínio de retenção urinária no Grupo M e bloqueio motor no Grupo R0,375.

ABSTRACT

Introducción: El dolor oncológico frecuentemente incapacita y desanima a los pacientes, adicionalmente produce frustración no solo al paciente sino también al equipo que realiza el cuidado. En un momento dado los opiodes ya no alivian el dolor y se requieren medidas coayuvantes para tener los mismos resultados. El objetivo de este trabajo fue comparar la eficacia analgésica con morfina + ketamina en relación a morfina sola en pacientes oncológicos que no responden a opioides. Métodos: El presente estudio observacional retrospectivo, fue realizado en el Instituto Oncológico Nacional "Dr. Juan Tanca Marengo" SOLCA-Guayaquil, con datos de enero del 2014 a diciembre del 2015. Se incluyeron todos los registros clínicos de pacientes mayores a 17 años que ingresaron a sala de urgencias o en hospitalización en quienes se realizó un tratamiento paliativo del dolor de tipo oncológico, con una escala de Karnofsky ≥ 40. El grupo 1 (G1) se conformó con pacientes cuyo tratamiento fue en base solamente con morfina con una respuesta adecuada, el Grupo 2 (G2) fue constituido con pacientes en quienes se usó morfina + Ketamina debido a su falta de respuesta previa solamente al uso de morfina. Se midió la percepción del dolor en la escala visual analógica (EVA), dosis de morfina usada (número de dosis de rescate), dosis de Ketamina usada, efectos secundarios. La muestra fue no probabilística, tipo censo. Resultados: 81 pacientes ingresaron al estudio, 34/43mujeres (79%) en G1 y 24/38 (63%) en G2 P=0.113.58. En ambos grupos EVA al ingreso 7 a 10 (severo), después de la intervención terapéutica en G1 4 ± 1.25, en G2 3 ± 1.50 P=0.78. Dosis de Morfina en G1 10 ± 12.5 mg, en G2 20 ± 27.5 mg P= 0.406. Rescate analgésico en G1 29/43 (67%) en G2 19/38 (50%) OR 0.483 (IC95% 0.196-1.188) P=0.113. Efectos adversos no fueron diferentes en ambos grupos. Conclusión: La Ketamina usada como coadyuvante con morfina permite mantener el control el dolor en el grupo de pacientes que habitualmente no responden a Morfina con dolor oncológico, sin aumentar los efectos adversos.

Introduction: Cancer pain frequently disables and discourages patients, additionally it produces frustration not only for the patient but also for the team that performs the care. At one point, opioids no longer relieve pain and co-adjuvant measures are required to achieve the same results. The objective of this study was to compare the analgesic efficacy with morphine + ketamine in relation to morphine alone in cancer patients who do not respond to opioids. Methods: The present retrospective observational study was carried out at the National Oncological Institute "Dr. Juan Tanca Marengo "SOLCA-Guayaquil, with data from January 2014 to December 2015. All clinical records of patients older than 17 years who were admitted to the emergency room or hospitalized who underwent palliative treatment of pain from Oncological type, with a Karnofsky scale ≥ 40. Group 1 (G1) was made up of patients whose treatment was based solely on morphine with an adequate response, Group 2 (G2) was made up of patients in whom morphine + was used Ketamine due to lack of response prior to morphine use only. The perception of pain was measured on the visual analog scale (VAS), dose of morphine used (number of rescue doses), dose of Ketamine used, side effects. The sample was non-probabilistic, census type. Results: 81 patients entered the study, 34/43 women (79%) in G1 and 24/38 (63%) in G2 P = 0.113.58. In both groups, VAS at admission 7 to 10 (severe), after the therapeutic intervention in G1 4 ± 1.25, in G2 3 ± 1.50 P = 0.78. Morphine dose in G1 10 ± 12.5 mg, in G2 20 ± 27.5 mg P = 0.406. Analgesic rescue in G1 29/43 (67%) in G2 19/38 (50%) OR 0.483 (95% CI 0.196-1.188) P = 0.113. Adverse effects were not different in both groups. Conclusion: Ketamine used as an adjuvant with morphine allows to maintain pain control in the group of patients who usually do not respond to morphine with cancer pain, without increasing adverse effects.

ABSTRACT

Introducción: La morfina es un alcaloide obtenido del opio. Su conocimiento y aplicaciones son desconocidas en la práctica médica diario. La utilización ineficiente de analgésicos produce que el dolor sea refractario. Entre los médicos existen reticencias al uso de opioides como la morfina por varios mitos que debemos desmentir. Objetivos: Evaluar el conocimiento de los médicos de diversas especialidades en el INCAN (Instituto Nacional del Cáncer) y el HRE (Hospital Regional de Encarnación) sobre la morfina, como sus formas de presentación, indicaciones, contraindicaciones y precio en el mercado libre de Paraguay. Materiales y métodos: Estudio descriptivo de corte transversal, los datos se recolectaron a través de una encuesta anónima auto administrada. La n fue de 41, entre médicos del INCAN y el HRE. Se utilizó la prueba estadística de Chi2 para el análisis estadístico. SPSS 20 fue utilizado. Resultados: El 46,3 % eran médicos del INCAN, el 53,7 % eran médicos del HRE. Edad media fue 30,17 años DE ± 5,56. el análisis estadístico con Chi2 cruzando variables centro y número de respuestas correctas de los integrantes no fue significativa. Los resultados en cuanto a las dosis, indicaciones y efectos secundarios fueron negativas para ambas entidades, reforzando un bajo nivel de conocimiento sobre las generalidades. La gran mayoría de los médicos refiere que su uso produce adicciones y depresión respiratoria. Conclusión: Se demuestra que hay desconocimiento sobre el uso de la morfina que imposibilita un tratamiento adecuado del dolor por los mitos y el miedo de los efectos secundarios.


Introduction: Morphine is an alkaloid obtained from opium. Its knowledge and applications are unknown in daily medical practice. The inefficient use of analgesics causes pain to be refractory. Among doctors there are reluctance to use opioids such as morphine for several myths that we must deny. Objectives: To evaluate the knowledge of doctors of various specialties at INCAN (National Cancer Institute) and HRE (Regional Hospital of Encarnación) about morphine, as its forms of presentation, indications, contraindications and price in the free market of Paraguay. Materials and methods: Descriptive cross-sectional study, data were collected through a self-administered anonymous survey. The number was 41, between INCAN and HRE doctors. The Chi2 statistical test was used for statistical analysis. SPSS 20 was used. Results: 46.3% were INCAN doctors, 53.7% were HRE doctors. Mean age was 30.17 years SD ± 5.56. The statistical analysis with Chi2 crossing center variables and number of correct answers of the members was not significant. The results regarding doses, indications and side effects were negative for both entities, reinforcing a low level of knowledge about the generalities. The vast majority of doctors report that its use causes addictions and respiratory depression. Conclusion: It is shown that there is ignorance about the use of morphine that makes it impossible to properly treat pain due to myths and fear of side effects.

ABSTRACT

Abstract Background: Postoperative Nausea and Vomiting (PONV) risk factors have not been defined for obstetric patients. In this study, our objective was to identify potential risk factors for PONV after cesarean sections performed under spinal anesthesia. Methods: One cohort of patients submitted to cesarean under spinal anesthesia was used to investigate potential risk factors for PONV. The best numerical risk factors were dichotomized using chi-squared method. A conditional independence (incremental association method) casual network was used to select the best predictors for PONV. Results: Two hundred and fifty of 260 patients remained in the study. Odds ratio for PONV of younger maternal age (< 25 years: 2.9 [1.49−5.96]), lower spinal bupivacaine dose (< 13 mg, inf [2.4-inf]), lower spinal morphine dose (< 80 mg, 0.03 [0−0.97]), history of motion sickness (2.5 [1.27−5.25]), significant nausea during the first trimester (0.3 [0.16−0.64]), intraoperative nausea and vomiting (8.2 [3.67−20.47]), and lower gestational age (< 38 weeks, 2.0 [1.01−4.08]) were statistically significant. The causal network selected absence of significant nausea during the first gestational trimester, intraoperative nausea, and gestational age < 38 weeks as the main direct risk factors for PONV. Conclusions: Intraoperative nausea and maternal age < 25 years were the main risk factors for PONV after cesareans under spinal anesthesia. Absence of self-reported nausea during the first trimester was a protective factor for post-cesarean nausea and vomiting.


Resumo Introdução: Os fatores de risco para náusea e vômitos pós-operatórios (NVPO) ainda não foram definidos para pacientes de obstetrícia. Neste estudo, nosso objetivo foi identificar potenciais fatores de risco para NVPO após parto cesariano realizado sob raquianestesia. Método: Uma coorte de pacientes submetidas a cesariana sob raquianestesia foi usada para investigar potenciais fatores de risco para NVPO. Os melhores fatores de risco numéricos foram dicotomizados por meio do método qui-quadrado. Uma rede casual de independência condicional (método de associação adicional) foi usada para selecionar os melhores preditores de NVPO. Resultados: Das 260 pacientes iniciais, 250 completaram o estudo. A razão de chances para NVPO foi estatisticamente significante para menor idade materna (< 25 anos: 2,9 [1,49−5,96]), dose mais baixa de bupivacaina raquidiana (< 13 mg, inf [2,4-inf]), dose mais baixa de morfina raquidiana (< 80 mg, 0,03 [0−0,97]), histórico de enjoo de movimento (2,5 [1,27−5,25]), náuseas importantes durante o primeiro trimestre (0,3 [0,16−0,64]), náusea e vômitos intraoperatórios (8,2 [3,67−20,47]) e menor idade gestacional (< 38 semanas, 2,0 [1,01−4,08]). A rede causal selecionou ausência de náuseas significativas durante o primeiro trimestre gestacional, náusea intraoperatória e idade gestacional < 38 semanas como os principais fatores de risco diretos para NVPO. Conclusões: Náusea intraoperatória e idade materna < 25 anos foram os principais fatores de risco para NVPO após cesariana sob raquianestesia. A ausência de náusea autorreferida durante o primeiro trimestre foi um fator protetor para náusea e vômitos após cesariana.

ABSTRACT

Abstract Objective This study aimed to investigate the impact of post-thoracotomy analgesia with dexmedetomidine and morphine on immunocytes. Methods A total of 118 patients with post-thoracotomy Patient-Controlled Intravenous Analgesia (PCIA) in our hospital from March 2016 to July 2018 were randomly selected and divided into the Composite (COM) Group (57 patients administered with dexmedetomidine [1.0 µg.kg-1 body weight] and morphine [0.48 mg.kg-1 body weight]) and the Morphine (MOR) group (61 patients administered with morphine [0.48 mg.kg-1]). The values of lymphocyte subsets (CD3+, CD4+, and CD8+) and Natural Killer cells in the peripheral blood of these two groups were detected by FACSCalibur flow cytometry at different time points (before anesthesia induction [T0], immediately after tracheal extubation [T1], 12 hours after surgery [T2], 24 hours after surgery [T3], 48 hours after surgery [T4], 72 hours after surgery [T5], and 7 days after surgery [T6]). The doses of morphine at T3 to T5 and the adverse reactions between the two groups were also recorded and compared. Results The CD3+ level and the CD4+/CD8+ ratio at T2 to T5 and the CD4+ level and NK cells at T3 to T5 were significantly higher in the COM Group than in the MOR Group (p< 0.05). The postoperative morphine dose and the incidence of postoperative itching, nausea, and vomiting were significantly lower in the COM Group than in the MOR Group (p< 0.05). Conclusions Dexmedetomidine combined with morphine for post-thoracotomy PCIA can improve the function of immunocytes, reduce morphine consumption, and reduce the adverse reactions during analgesia induction.


Resumo Objetivo Estudar o impacto em linfócitos causado pelo uso da dexmedetomidina associada à morfina para analgesia pós-toracotomia. Método Um total de 118 pacientes utilizando Analgesia Intravenosa Controlada pelo Paciente (AICP) pós-toracotomia em nosso hospital, de março de 2016 a julho de 2018, foram selecionados aleatoriamente e divididos em dois grupos: o Grupo Combinado [COM, 57 pacientes que receberam dexmedetomidina (1,0 µg.kg-1 de peso corpóreo) associada à morfina (0,48 mg.kg-1 de peso corpóreo)] e o Grupo Morfina [MOR, 61 pacientes, que receberam somente morfina (0,48 mg.kg-)]. Os valores dos subconjuntos de linfócitos (CD3+, CD4+ e CD8+) e das células NK no sangue periférico desses dois grupos foram medidos por citometria de fluxo FACSCalibur em diferentes momentos do estudo [antes da indução anestésica (T0), imediatamente após extubação traqueal (T1), 12 horas após a cirurgia (T2), 24 horas após a cirurgia (T3), 48 horas após a cirurgia (T4), 72 horas após a cirurgia (T5) e 7 dias após a cirurgia (T6)]. As doses de morfina do momento T3 ao T5 e as reações adversas entre os dois grupos também foram registradas e comparadas. Resultados O nível de CD3+ e a razão CD4+/CD8+ de T2 a T5, e o nível de CD4+ e as células NK de T3 a T5 do Grupo COM foram significantemente maiores (p< 0,05) quando comparados ao Grupo MOR. A dose de morfina no pós-operatório e a incidência de prurido, náusea e vômito no pós-operatório foram significantemente menores no grupo MOR (p< 0,05). Conclusões Dexmedetomidina combinada com morfina para AICP no período pós-toracotomia pode melhorar a função dos linfócitos, reduzir o consumo de morfina e diminuir reações adversas durante a analgesia.

ABSTRACT

O objetivo deste estudo foi avaliar os efeitos analgésicos transoperatórios da infusão contínua de morfina e cetamina, associada ou não à lidocaína, em gatas submetidas à OSH eletiva. Foram utilizadas 16 fêmeas adultas, hígidas, pré-medicadas com acepromazina (0,1mg/kg) e morfina (0,5mg/kg), ambas pela via intramuscular, induzidas com cetamina (1mg/kg) e propofol (4mg/kg), pela via intravenosa, e mantidas sob anestesia geral inalatória com isoflurano a 1,4 V%. Os animais foram alocados aleatoriamente em dois grupos: grupo morfina, lidocaína e cetamina (MLK, n=8), que recebeu bolus de lidocaína (1mg/kg), pela via IV, seguido de infusão de morfina, lidocaína e cetamina (0,26mg/kg/h, 3mg/kg/h e 0,6mg/kg/h, respectivamente); e grupo morfina e cetamina (MK, n=8), que recebeu bolus de solução salina, seguido de infusão de morfina e cetamina, nas mesmas doses do MLK. Os momentos avaliados foram: M0, basal, cinco minutos após a indução; M1, imediatamente após a aplicação do bolus de lidocaína ou solução salina; M2, M3, M4 e M5, a cada cinco minutos, até completar 20 minutos do início da infusão; M6, após a incisão da musculatura; M7, após pinçamento do primeiro pedículo ovariano; M8, após pinçamento do segundo pedículo ovariano; M9, após pinçamento da cérvix; M10, após sutura da musculatura; M11, ao final da cirurgia; e M12, M13 e M14, intervalos de cinco minutos, até completar uma hora de infusão. A FP no M0 foi maior no MLK quando comparado ao MK. Em ambos os grupos, a PAS foi maior no M7 e no M8 em relação ao M0, porém no MK, além da PAS, a FP foi maior do M7 ao M13, assim como a f. Os animais do MK necessitaram de um número maior de resgates transoperatorios, total de 23, do que o MLK, total de sete. Conclui-se que a adição de lidocaína incrementou a analgesia oferecida, reduzindo o número de resgates analgésicos transoperatórios, a dose total de fentanil, bem como a probabilidade de os animais necessitarem dese tipo de resgate.(AU)


The aim of this study was to evaluate the trans-operative analgesics, continuous infusion of morphine and ketamine, with or without lidocaine in cats undergoing elective OSH. Sixteen adult cats were used, otherwise healthy, pre-medicated with acepromazine (0.1mg/kg) and morphine (0.5mg/kg), both intramuscularly, induced with ketamine (1mg/kg) and propofol (4mg/kg), intravenous, maintained under general inhalation anesthesia with isoflurane 1.4 V%. The animals were randomly allocated into two groups: morphine, lidocaine and ketamine (MLK, n= 8), which received intravenous bolus of lidocaine (1mg/kg) followed by infusion of morphine, lidocaine and ketamine (0.26mg / kg/h, 3mg / kg/h and 0.6mg / kg/h, respectively); Morphine and ketamine (MK, n= 8), who received bolus of saline followed by infusion of morphine and ketamine at the same doses of MLK. The evaluated moments were: M0, basal, 5 minutes after induction; M1 immediately after the application of lidocaine bolus injection or saline; M2, M3, M4 and M5, every 5 minutes to complete 20 minutes after the start of infusion; M6, after the incision of the musculature; M7, after clamping of the first ovarian pedicle; M8, after clamping of the second ovarian pedicle; M9, after clamping of the cervix; M10, after suturing of the musculature; M11, at the end of surgery; And M12, M13 and M14, 5 minute intervals until completing one hour of infusion. The time to extubating and full recovery of animals, and the need for rescue analgesic fentanyl intraoperatively were also evaluated. HR in M0 was higher in MLK when compared to MK. In both groups the SBP was higher in M7 and M8 compared to M0, but the MK, addition of SAP, HR was greater M7 to M13, as well as f. MK animals required a greater number of trans-operative rescues than the MLK. It was concluded that the addition of lidocaine to the protocol using morphine and ketamine increased its analgesia.(AU)

ABSTRACT

Preclinical studies suggest that the GABA receptor is a potential target for treatment of substance use disorders. Baclofen (BLF), a prototypical GABA receptor agonist, is the only specific GABA receptor agonist available for application in clinical addiction treatment. The nucleus accumbens shell (AcbSh) is a key node in the circuit that controls reward-directed behavior. However, the relationship between GABA receptors in the AcbSh and memory reconsolidation was unclear. The aim of this study was to investigate the effect of intra-AcbSh injection of BLF on the reconsolidation of morphine reward memory. Male C57BL/6J mice were used to establish morphine conditioned place preference (CPP) model and carry out morphine reward memory retrieval and activation experiment. The effects of intra-AcbSh injection of BLF on morphine-induced CPP, reinstatement of CPP and locomotor activity were observed after environmental cues activating morphine reward memory. The results showed that intra-AcbSh injection of BLF (0.06 nmol/0.2 μL/side or 0.12 nmol/0.2 μL/side), rather than vehicle or BLF (0.01 nmol/0.2 μL/side), following morphine reward memory retrieval abolished morphine-induced CPP by disrupting its reconsolidation in mice. Moreover, this effect persisted for more than 14 days, which was not reversed by a morphine priming injection. Furthermore, intra-AcbSh injection of BLF without morphine reward memory retrieval had no effect on morphine-associated reward memory. Interestingly, administration of BLF into the AcbSh had no effect on the locomotor activity of mice during testing phase. Based on these results, we concluded that intra-AcbSh injection of BLF following morphine reward memory could erase morphine-induced CPP by disrupting its reconsolidation. Activating GABA receptor in AcbSh during drug memory reconsolidation may be a potential approach to prevent drug relapse.

ABSTRACT

OBJECTIVE@#To observe the effect of early intervention of bone-nearby acupuncture (BNA) combined with electroacupuncture (EA) on the expression of histone deacetylase1(HDAC1), histone deacetylase 2 (HDAC2) andμ-opioid recepter (MOR) in dorsal root ganglia (DRG) of bone cancer pain-morphine tolerance (BCP-MT) rats, and to explore its possible mechanism.@*METHODS@#A total of 35 SD rats were randomized into a sham BCP group (=6), a BCP group (=7), a MT group (=7), a BNA+EA group (=8) and a shame BNA group (=7). Except of the sham BCP group, cancer cell inoculation operation at left tibia was given in the other 4 groups to establish the bone cancer pain model. In the MT group, the BNA+EA group and the shame BNA group, intraperitoneal injection of morphine hydrochloride was given to establish the morphine tolerance model. After the operation, bone-nearby acupuncture combined with electroacupuncture was applied at "Zusanli" (ST 36) and "Kunlun" (BL 60) in the BNA+EA group, with dilatational wave, 2 Hz/100 Hz in frequency, 0.5 to 1.5 mA in intensity. Intervention in the shame BNA group was applied at the same time and acupoints as those in the BNA+EA group, the needles were pierced the skin without any electrical stimulation. The needles were retained for 30 min, once a day for continuous 7 days in both BNA+EA and shame BNA groups. Before and 10, 11, 15, 22 days after the operation, the left paw withdrawal threshold (PWT) was measured in the 5 groups. The levels of HDAC1, HDAC2 and MOR in DRG were detected by Western blot.@*RESULTS@#Ten days after the cancer cell inoculation operation, the PWT of the BCP, MT, BNA+EA and sham BNA groups was decreased compared with the sham BCP group (0.05); the PWT of the BNA+EA group was increased compared with the MT and sham BNA group (<0.01). In the BCP group, the DRG levels of HDAC1 and HDCA2 were increased, while the level of MOR was decreased compared with the sham BCP group (<0.05, <0.01). In the MT group, the DRG level of HDAC1 was increased compared with the BCP group (<0.05). In the BNA+EA group, the DRG level of HDAC1 was decreased compared with the MT group and the sham BNA group (<0.01, <0.05), while the level of MOR was increased (<0.01).@*CONCLUSION@#Early intervention of bone-nearby acupuncture combined with electroacupuncture can relieve the morphine tolerance in bone cancer pain rats, it may relate to down-regulating the expression of HDAC1 and up-regulating the expression of MOR in the dorsal root ganglia.

ABSTRACT

@#Introduction: Intrathecal morphine, commonly administered at doses of 100 to 200 mcg, is a popular choice for post-cesarean analgesia; however, a trade-off between opioid analgesia and side effects exists. This study was conducted to determine the lowest dose of intrathecal morphine that will provide adequate analgesia with the least side effects among post-cesarean patients. Methods: Sixty term parturients for cesarean delivery under spinal anesthesia were randomized into three treatment groups to receive 50, 100 or 150 mcg of intrathecal morphine with a standard multimodal painregimen and intravenous tramadol as needed. Pain scores, demand for rescue analgesic, and incidence of adverse effects (nausea, vomiting, and pruritus) during the first 24 hours’ post-spinal anesthesia were recorded and compared between groups. Results: Pain scores and demand for rescue doses of tramadol were higher for the 50-mcg group as compared to the other groups. There was no significant difference in pain scores between the 100 and 150-mcg groups. No rescue dose of tramadol was necessary in the 100 and 150-mcg groups. No significant difference was seen in the incidence and severity of nausea and vomiting across treatment groups. The incidence and severity of pruritus were significantly higher in the 150-mcg group. No significant difference was noted in the incidence and severity of pruritus between the 50 and 100-mcg groups. Conclusion: A dose of 100 mcg of intrathecal morphine, in combination with a multimodal regimen, provides adequate analgesia with the least side effects.

Objective: The study's purpose has been to address the state of the art in investigations such as clinical trials, systematic reviews with metaanalysis and case studies, which report how to minimize opioid-induced constipation in patients undergoing palliative care. Methods: This is an exploratory study through an integrative review of four databases addressing published articles from 2013 to 2017. Results: A total of 117 publications were presented, which 17 presented the inclusion criteria. The studies describe the prevalence of constipation rates induced by the use of opioids. Conclusion: Although these drugs alleviate pain, the adverse reactions may generate discomfort and loss of the patient's life quality. There are limited data on the treatment of constipation. It was observed that few authors mentioned diet as a helper on this situation, emphasizing the use of medications. Further studies should be encouraged aiming to find the balance between analgesia and reduction of adverse effects

ABSTRACT

Abstract Background and objectives: The frequent onset of hemidiaphragmatic paralysis during interscalene block restricts its use in patients with respiratory insufficiency. Supraclavicular block could be a safe and effective alternative. Our primary objective was to assess the incidence of hemidiaphragmatic paralysis following ultrasound-guided supraclavicular block and compare it to that of interscalene block. Methods: Adults warranting elective shoulder surgery under regional anesthesia (Toulouse University Hospital) were prospectively enrolled from May 2016 to May 2017 in this observational study. Twenty millilitres of 0.375% Ropivacaine were injected preferentially targeted to the "corner pocket". Diaphragmatic excursion was measured by ultrasonography before and 30 minutes after regional anesthesia. A reduction ≥25% in diaphragmatic excursion during a sniff test defined the hemidiaphragmatic paralysis. Dyspnoea and hypoxaemia were recorded in the recovery room. Predictive factors of hemidiaphragmatic paralysis (gender, age, weight, smoking, functional capacity) were explored. Postoperative pain was also analysed. Results: Forty-two and 43 patients from respectively the supraclavicular block and interscalene block groups were analysed. The incidence of hemidiaphragmatic paralysis was 59.5% in the supraclavicular block group compared to 95.3% in the interscalene block group (p < 0.0001). Paradoxical movement of the diaphragm was more common in the interscalene block group (RR = 2, 95% CI 1.4-3; p = 0.0001). A similar variation in oxygen saturation was recorded between patients with and without hemidiaphragmatic paralysis (p = 0.08). No predictive factor of hemidiaphragmatic paralysis could be identified. Morphine consumption and the highest numerical rating scale numerical rating scale (NRS) at 24 hours did not differ between groups. Conclusions: Given the frequent incidence of hemidiaphragmatic paralysis following supraclavicular block, this technique cannot be recommended for patients with an altered respiratory function.


Resumo Justificativa e objetivos: O aparecimento frequente de paralisia hemidiafragmática durante o bloqueio interescalênico restringe seu uso em pacientes com insuficiência respiratória. O bloqueio supraclavicular pode ser uma opção segura e eficaz. Nosso objetivo primário foi avaliar a incidência de paralisia hemidiafragmática após bloqueio supraclavicular guiado por ultrassom e compará-lo com o bloqueio interescalênico. Métodos: Os adultos agendados para cirurgia eletiva do ombro sob anestesia regional (Hospital Universitário de Toulouse) foram prospectivamente incluídos neste estudo observacional, de maio de 2016 a maio de 2017. Vinte mililitros de ropivacaína a 0,375% foram injetados, preferencialmente objetivando a interseção da primeira costela e da artéria subclávia. A excursão diafragmática foi medida por ultrassonografia antes e 30 minutos após a anestesia regional. Uma redução ≥ 25% na excursão diafragmática durante um sniff test definiu a paralisia hemidiafragmática. Dispneia e hipoxemia foram registradas na sala de recuperação. Fatores preditivos de paralisia hemidiafragmática (sexo, idade, peso, tabagismo, capacidade funcional) foram explorados. A dor pós-operatória também foi avaliada. Resultados: Quarenta e dois e 43 pacientes dos grupos bloqueio supraclavicular e bloqueio interescalênico, respectivamente, foram avaliados. A incidência de paralisia hemidiafragmática foi de 59,5% no grupo bloqueio supraclavicular em comparação com 95,3% no grupo bloqueio interescalênico (p < 0,0001). O movimento paradoxal do diafragma foi mais comum no grupo bloqueio interescalênico (RR = 2, 95% IC 1,4-3; p = 0,0001). Uma variação semelhante na saturação de oxigênio foi registrada entre os pacientes com e sem paralisia hemidiafragmática (p = 0,08). Nenhum fator preditivo de paralisia hemidiafragmática pôde ser identificado. O consumo de morfina e o maior escore na escala numérica (NRS) em 24 horas não diferiram entre os grupos. Conclusão: Devido à frequente incidência de paralisia hemidiafragmática após bloqueio supraclavicular, essa técnica não pode ser recomendada para pacientes com função respiratória alterada.

ABSTRACT

Abstract Background Postoperative pain represents an important concern when remifentanil is used for total intravenous anesthesia because of its ultrashort half-life. Longer acting opioids, such as sufentanil, have been used during induction of remifentanil-based total intravenous anesthesia as a means to overcome this shortcoming. However, the effectiveness and safety of such strategy still lacks evidence from randomized clinical trials. Hence, we aimed to assess the postoperative analgesic efficacy and safety of a single dose of sufentanil administered during the induction of remifentanil-based total intravenous anesthesia. Methods Forty patients, scheduled for elective open abdominal surgery, were randomized to receive remifentanil-based total intravenous anesthesia with or without a single dose of sufentanil upon induction. We assessed the postoperative morphine consumption administered through a patient-controlled analgesia pump. Self-reported pain scores and the occurrence of nausea, vomiting, pruritus, agitation, somnolence and respiratory depression were also assessed up to 2 days after surgery. Results The mean difference between the sufentanil and control groups regarding morphine consumption in the post-anesthetic care unit and at 12, 24 and 48 h after surgery were -7.2 mg (95%CI: -12.5 to -2.1, p < 0.001), -3.9 mg (95%CI: -11.9 to 4.7, p = 0.26), -0.6 mg (95%CI: (-12.7 to 12.7, p = 0.80), and -1.8 mg (95%CI: (-11.6 to 15.6, p = 0.94), respectively. Neither self-reported pain nor the incidence of adverse events were significantly different between groups at any time point. Conclusion Our findings suggest that the administration of sufentanil during induction of remifentanil-based total intravenous anesthesia is associated with decreased early postoperative opioid consumption.


Resumo Justificativa A dor pós-operatória é uma grande preocupação quando o remifentanil é usado para anestesia intravenosa total devido à sua meia-vida ultracurta. Os opioides de ação mais longa, como o sufentanil, têm sido usados durante a indução de anestesia intravenosa total à base de remifentanil como um meio de superar essa deficiência. Porém, a eficácia e segurança de tal estratégia ainda precisam de evidências advindas de ensaios clínicos randômicos. Portanto, objetivamos avaliar a eficácia analgésica e a segurança pós-operatória de uma dose única de sufentanil administrada durante a indução de anestesia intravenosa total à base de remifentanil. Métodos Quarenta pacientes eletivamente agendados para cirurgia abdominal aberta foram randomizados para receber anestesia intravenosa total à base de remifentanil, com ou sem uma dose única de sufentanil, após a indução da anestesia. Avaliamos o consumo de morfina no pós-operatório, administrado através de uma bomba de analgesia controlada pelo paciente. Os escores de dor autorrelatados e a ocorrência de náusea, vômito, prurido, agitação, sonolência e depressão respiratória também foram avaliados até dois dias após a cirurgia. Resultados A diferença média entre os grupos sufentanil e controle em relação ao consumo de morfina em sala de recuperação pós-anestesia e após 12, 24 e 48 horas da cirurgia foi de -7,2 mg (IC 95%: -12,5 a -2,1, p < 0,001), -3,9 mg (IC 95%: -11,9 a 4,7, p = 0,26), -0,6 mg (IC 95%: (-12,7 a 12,7, p = 0,80) e -1,8 mg (IC 95%: -11,6 para 15,6, p = 0,94), respectivamente. Não houve diferença significativa tanto nos escores de dor autorrelatados, quanto na incidência de eventos adversos entre os grupos. Conclusão Nossos achados sugerem que a administração de sufentanil durante a indução de anestesia intravenosa total à base de remifentanil está associada à redução do consumo de opioides no pós-operatório imediato.

ABSTRACT

Abstract Background: Pain management committee established a pain performance improvement plan in 2012. Objectives: The aim of the study was to assess the trends in analgesic consumption in a tertiary teaching hospital and the associated economic impact. Methods: A descriptive, retrospective study was conducted between 2011 and 2015. The analysis included: anti-inflammatory and antirheumatic products non-steroids, opioid analgesics and other analgesics and antipyretics. Data are converted into DDD/100 bed-days to analyze consumption trends. Main outcome measure: assessment of the analgesic consumption after the implementation of a pain performance improvement plan. Results: Overall, non-steroidal anti-inflammatory and antirheumatic products consumption decreased in 24.8 DDD/100 bed-days (-28.3%), accounting for most of the total analgesic consumption decrease (-13%) and total cost (-44.3%). Opioid consumption increased markedly from 22.3 DDD/100 bed-days in 2011 to 26.5 DDD/100 bed-days in 2015 (+18.9%). In 2011, the most consumed opioid was morphine (8.6 DDD/100 bed-days). However, there was an increasing trend in fentanyl consumption (from 8.1 to 12.1 DDD/100 bed-days in 2015), which resulted in fentanyl replacing morphine from the most consumed opioid in 2015 (12.1 DDD/100 bed-days). In 2015, the group of other analgesics and antipyretics represented 46.2% of the total analgesic consumption. Acetaminophen was the most commonly consumed analgesic drug (53.2 DDD/100 bed-days in 2015) and had the highest total cost, it represented 55.4% of the overall cost in 2015. Conclusion: Opioid consumption showed an increasing trend during the 5 year period, with fentanyl replacing morphine as the most used opioid. In general, analgesics diminished use was due to the decreasing trend of consumption of non-steroidal anti-inflammatory and antirheumatic products.


Resumo Justificativa: A Comissão para o Manejo da Dor estabeleceu um plano de melhoria no controle da dor em 2012. Objetivo: Avaliar as tendências do consumo de analgésicos em um hospital de ensino terciário e o impacto econômico associado. Métodos: Estudo descritivo, retrospectivo, feito entre 2011 e 2015. A análise incluiu: produtos anti-inflamatórios e antirreumáticos não esteroides, analgésicos opioides e outros analgésicos e antipiréticos. Os dados foram convertidos em DDD/100 leitos-dia para analisar as tendências de consumo. Principal medida do desfecho: avaliação do consumo de analgésicos após o estabelecimento de um plano de melhoria no controle da dor. Resultados: O consumo total de produtos anti-inflamatórios e antirreumáticos não esteroides diminuiu em 24,8 DDD/100 leitos-dia (-28,3%), representando a maior parte da redução total do consumo de analgésicos (-13%) e o custo total (-44,3%). O consumo global de opioides aumentou acentuadamente de 22,3 DDD/100 leitos-dia em 2011 para 26,5 DDD/100 leitos-dia em 2015 (+18,9%). Em 2011, o opioide mais consumido foi a morfina (8,6 DDD/100 leitos-dia). No entanto, houve uma tendência crescente no consumo de fentanil (de 8,1 para 12,1 DDD/100 leitos-dia em 2015), o que resultou na substituição de morfina por fentanil como o opioide mais consumido em 2015 (12,1 DDD/100 leitos-dia). Em 2015, o grupo dos outros analgésicos e antipiréticos representou 46,2% do consumo total de analgésicos. Acetaminofeno foi o analgésico mais consumido (53,2 DDD/100 leitos-dia em 2015) e teve o maior custo total, representou 55,4% do custo total em 2015. Conclusão: O consumo de opioides mostrou uma tendência crescente durante o período de cinco anos, fentanil substituiu morfina como o opioide mais usado. Em geral, o uso diminuído de analgésicos foi devido à tendência decrescente do consumo de produtos anti-inflamatórios e antirreumáticos não esteroides.
