Anestesia total intravenosa para tratamento endodôntico em Panthera leo ­ relato de caso / Total intravenous anesthesia for endodontic treatment in Panthera leo ­ case report

Animais presentes em zoológicos frequentemente necessitam de captura e anestesia para a realização de procedimentos clínicos e cirúrgicos. A anestesia total intravenosa apresenta vantagens como redução do estresse cirúrgico e menor depressão cardiovascular e respiratória. Entretanto, ainda são escassas as pesquisas dedicadas dentro deste contexto. Nesse sentido, o objetivo deste relato foi avaliar o protocolo anestésico empregado, visando um procedimento seguro e passível de reversão para a espécie silvestre selecionada. Acompanhou-se a anestesia de um leão (Panthera leo), macho, adulto, proveniente do Zoológico Municipal de Curitiba, submetido a procedimento endodôntico. A medicação pré-anestésica constituiu-se de dexmedetomidina (6 µg/kg), metadona (0,2 mg/kg), midazolam (0,1 mg/kg) e tiletamina-zolazepam (1,2 mg/kg). A indução foi realizada com propofol (1,5 mg/kg) e o animal foi intubado. Visando promover analgesia local, foi realizado bloqueio infraorbitário esquerdo com 5 mL de lidocaína a 2%. A manutenção foi realizada por meio do fornecimento de propofol (0,02-0,1 mg/kg/h), dexmedetomidina (0,5 µg/kg/h) e remifentanil (5 µg/kg/h). O paciente apresentou sedação profunda e foi mantido em plano anestésico cirúrgico; todos os parâmetros fisiológicos monitorados permaneceram estáveis durante todo o procedimento. Após 55 minutos de anestesia o paciente apresentava sustentação espontânea da cabeça, quando foi novamente transportado ao zoológico para soltura no recinto. A ambulação foi considerada normal pelos observadores no zoológico seis horas após a anestesia. Pôde-se concluir que o protocolo realizado se mostrou tanto eficaz quanto seguro para a referida espécie encaminhada ao procedimento em questão.

Zoo animals often require capture and anesthesia in order to undergo clinical and surgical procedures. Total intravenous anesthesia has advantages such as reduced surgical stress and less cardiovascular and respiratory depression. However, specific research on this matter is still scarce. Therefore, the present report aims to evaluate the anesthetic protocol employed, seeking a safe and reversible procedure for the selected wild species. A male adult lion (Panthera leo), from the Zoológico Municipal de Curitiba, was subjected to an endodontic anesthesia, under close monitoring. The pre-anesthetic medication consisted of dexmedetomidine (6 µg/kg), methadone (0.2 mg/kg), midazolam (0.1 mg/kg) and tiletamine-zolazepam (12 mg/kg). Induction was performed with propofol (1 mg/kg) and the animal was intubated. In order to promote local analgesia, a left infraorbital block was implemented with 5 mL of 2% lidocaine. Maintenance was undertaken by supplying propofol (0.02-0.1 mg/kg/min), dexmedetomidine (0.5 µg/kg/h) and remifentanil (5 µg/kg/h). The patient exhibited deep sedation and followed the surgical anesthetic plan; all the monitored physiological parameters remained stable throughout the procedure. After 55 minutes of anesthesia the patient showed spontaneous head support, when it was transported back to the zoo. The ambulation was considered normal by the zoo observers 6 hours after the anesthesia. It was concluded that the protocol was both effective and safe for the referred species undergone the procedure reported.

Perception douloureuse et moyens de lutte en hystéroscopie au cabinet / Pain perception and management during office hysteroscopy

Contexte & objectif. L'hystéroscopie a connu des avancées majeures ces dernières à différents points de vue. Elle est passée d'une procédure nécessitant une hospitalisation à une procédure ambulatoire, de même elle a quitté la salle d'opération pour rejoindre le cabinet de consultation. Mais, un des problèmes à ces progrès, c'est la gestion de la douleur au cours et après la procédure. La présente revue passe en revue les différents moyens, tant pharmacologiques que non pharmacologiques utilisés pour la réduction de la perception de la douleur au cours d'une hystéroscopie au cabinet. Méthodes. Il s'agissait d'une revue exhaustive de la littérature (Pubmed, Medline, cochrane library) concernant les méta-analyses, revues de la littérature et essais randomisés publiés sur le sujet et en anglais de 2003 à 2021. Conclusion. Plusieurs moyens avec une efficacité très variable sont proposés pour réduire la douleur au cours de l'hystéroscopie au cabinet. Les auteurs s'accordent sur le fait que la bonne maitrise de l'anatomie de la filière génitale féminine vue en hystéroscopie, l'approche vaginoscopique et la psychothérapie permettent de diminuer significativement la douleur au cours de l'hystéroscopie et donc d'en améliorer la tolérance sans nécessité une quelconque anesthésie ou analgésie

Pentazocine versus tramadol-paracetamol combination as analgesia in labor: A randomized controlled trial

Objectives: Labor should be a satisfactory experience and effective pain management should be employed as recommended by the American Congress of Obstetricians and Gynaecologists. In developing countries, pain management in labor is still a big challenge and the search for the ultimate labor analgesia is still ongoing. The objectives of the study were to determine whether the synergistic analgesic effect of the combination of tramadol and paracetamol will produce analgesia comparable to pentazocine with a better side effect profile. Material and Methods: This was a randomized controlled, double-blinded trial of tramadol-paracetamol combination versus pentazocine as labor analgesia and was carried out at the University of Abuja Teaching Hospital, Abuja, between June 2018 and March 2019. A total of 218 eligible parturients recruited at term, were counseled on labor analgesia, its benefits, and the options made available to them and educated on the pain scoring system. Parturients were allocated into two groups using computer-generated numbers with the WINPEPI software. Group A was given tramadol-paracetamol combination, while Group B received pentazocine, both at standard doses. Hourly pain scores, APGAR scores, labor duration, patients' satisfaction, and side effects were collated. The level of significance was set at <0.05. Results: Tramadol-paracetamol was administered to 109 (50.9%) while pentazocine was administered to105 (49.1%) of the study participants. The mean age in the tramadol-paracetamol group was 29.6 ± 4.8 years, and in the pentazocine group, it was 28.8 ± 4.5 years. The difference in pain scores on the visual analog scale was statistically significant at the 3rd and 4th h (P = 0.02 and 0.004), but not significant in the 1st and 2nd h (P = 0.05 and 0.22) in the two groups. Overall, the average pain score in the tramadol-paracetamol group was significantly higher compared to the pentazocine group (5.27 ± 1.86 vs. 4.72 ± 1.54; P = 0.02). The 1st and 5th min APGAR scores (P = 0.44 and 0.67, respectively) of neonates in the tramadol-paracetamol and pentazocine groups were comparable. Nausea and drowsiness occurred more frequently in the pentazocine group at P-values of 0.047 and 0.0015, respectively. There was no statistically significant difference in the duration of labor between the tramadol-paracetamol and pentazocine groups. not statistically significant, a higher proportion of parturients in the pentazocine group was satisfied compared with the tramadol-paracetamol group (71.4% vs. 63.3%; P = 0.13).Conclusion: This study showed that intravenous pentazocine provides better pain relief in labor, but the tramadol-paracetamol combination has fewer side effects

Parálisis diafragmática asociada al bloqueo interescalénico en cirugía de hombro: la utilidad de la ecografía diafragmática como herramienta diagnóstica / Phrenic paresis associated with interscalene block in shoulder surgery. Utility of diaphragm ultrasound examination

Introducción: El bloqueo interescalénico se utiliza de forma estandarizada durante la cirugía mayor de hombro, sin embargo, ninguna técnica realizada por encima de la clavícula ha demostrado reducir la tasa de bloqueo del nervio frénico por debajo del 20%. El interés en buscar una prueba diagnóstica que permita identificar la afectación del nervio frénico ha ido en incremento en los últimos años y varias han sido las pruebas diagnósticas empleadas. El objetivo de este trabajo es evaluar la utilidad clínica del ultrasonido para identificar la parálisis hemidiafragmática posterior al bloqueo interescalénico para la cirugía de hombro.Materiales y métodos: estudio diagnóstico observacional prospectivo en treinta y tres pacientes programados para cirugía de hombro. Se les realizó una espirometría forzada y se evaluó el grosor del músculo diafragma. Estas determinaciones se realizaron antes y a los veinte minutos de realizar el bloqueo interescalénico.Resultados: el total de los pacientes estudiados (100%) presentó bloqueo del nervio frénico según uno o los dos métodos utilizados en este estudio para su diagnóstico. Todos los pacientes presentaron variaciones en la ratio del grosor diafragmático en el lado del bloqueo frénico por debajo de 1.2.Conclusión: la exploración ecográfica del diafragma es una gran herramienta para la examinación de una víscera cuya alteración implica graves trastornos en el paciente crítico, a su vez el índice del grosor diafragmático <1.2 puede ser de utilidad en el diagnóstico de paresia frénica asociada al bloqueo del plexo braquial a nivel interescalénico. Tipo de Estudio: Diagnóstico prospectivo. Nivel de Evidencia: II

Introduction: the interscalene block is used in a standardized way during major shoulder surgery, however, no technique performed above the clavicle has been shown to reduce the rate of phrenic nerve block below 20%. The interest for a diagnostic test to allows identifying the involvement of the phrenic nerve has been increasing in recent years and several diagnostic tests have been used. The purpose of this article is to evaluate the clinical utility of ultrasound to identify hemidiaphragmatic paralysis after interscalene block for shoulder surgery.Materials and methods: prospective observational diagnostic study in thirty-three patients scheduled for shoulder surgery. A forced spirometry was performed and the thickness of the diaphragm muscle was evaluated with ultrasound. These determinations were made before and twenty minutes after performing the interscalene block.Results: all the patients studied (100%) presented phrenic nerve block according to one or the two methods used in this study for its diagnosis. All patients presented variations in the diaphragm thickness ratio on the side of the phrenic block below 1.2.Conclusion: the ultrasound examination of the diaphragm is a great tool for the examination of a viscera whose alteration implies serious disorders in the critical patient, in turn, the diaphragm thickness index <1.2 can be useful in the diagnosis of phrenic paresis associated with interscalene brachial plexus block.

Current status and research advances on drug sedation and analgesia in burn children / 中华烧伤杂志

Children are high-risk groups of burns, with unique physiological, psychological, and anatomical states, and the management of anxiety and pain for burn children are extremely challenging. Non-pharmacological interventions are very important for pain management in burn children, but are often inadequate for treating pain and anxiety, so pharmacological sedation and analgesia are necessary. This article reviewed the clinical treatment and research progress in this field in the past 10 years at home and abroad, including the pain assessment of burn children, monitoring in sedative and analgesic treatment, main therapeutic drugs and research progress, and some controversies in clinical practice. Besides, some suggestions have been put forward for clinical reference.

Effects of continuous goal-directed analgesia on fluid resuscitation of massive burn patients during shock / 中华烧伤杂志

Objective: To investigate the effects of continuous goal-directed analgesia on fluid resuscitation during shock stage in patients with massive burns, providing a basis for rational optimization of analgesia protocols in patients with burn shock. Methods: A retrospective case series study was conducted. One hundred and thirty-six patients with massive burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital from January 2015 to December 2020, and the patients were divided into continuous analgesia (CA) group (68 cases,with average age of 44 years old) and intermittent analgesia (IA) group (68 cases,with average age of 45 years old) according to whether sufentanil injection was continuously used for intravenous analgesia during the shock stage. The patients in the 2 groups were predominantly male. Before and at 72 h of treatment, the severity of disease and trauma pain of patients in the 2 groups were scored by the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and the visual analogue scale (VAS). Hematocrit, heart rate, mean arterial pressure (MAP), central venous pressure (CVP), oxygen saturation in central venous blood (ScvO2), rehydration coefficient, blood lactate value, hourly urine output, and the adverse reactions such as hypotension, nausea, vomiting, dizziness, skeletal muscle tonicity, respiratory depression, bradycardia, pruritus, and drug addiction of patients in the 2 groups during the treatment were recorded at the 1st, 2nd, and 3rd 24 h post-injury. Data were statistically analyzed with analysis of variance for repeated measurement, paired or independent sample t test, Bonferroni correction,chi-square test and Mann-Whitney U test. Results: Before treatment, APACHE Ⅱ and VAS scores of patients in the 2 groups were close (with t values of -0.67 and 0.32, respectively, P>0.05); At 72 h of treatment, APACHE Ⅱ and VAS scores of patients in CA group were 8.5±2.2 and 2.5±1.6, both of which were significantly lower than (15.2±3.0) and (7.9±2.0) of patients in IA group, respectively (with t values of -14.94 and -17.46, respectively, P<0.01). Compared with the pre-treatment period, the APACHE Ⅱ and VAS scores of patients in IA group decreased significantly at 72 h of treatment (with t values of 11.35 and 30.59, respectively, P<0.01); the changes in APACHE Ⅱ and VAS scores of patients at 72 h of treatment in comparison with those of patients before treatment in CA group were all similar to those of patients in IA group (with t values of 4.00 and 4.82, respectively, P<0.01). Compared with those of patients in IA group, there were no significant changes in CVP, hematocrit, heart rate, ScvO2, and MAP of patients in CA group at all three 24 h post-injury (with t values of <0.01, 0.12, 2.10, 1.55, 0.03; 0.13, 0.22, <0.01, 0.17, 0.49; 0.63, 0.06, 0.04, 2.79, and 2.33, respectively, P>0.05). Compared with those of patients in IA group at the 1st 24 h post-injury, CVP, ScvO2 and MAP of patients were significantly higher at the 2nd and 3rd 24 h post-injury (with t values of -10.10, -9.31, -8.89; -10.81, -4.65, and -9.43, respectively, P<0.01), and the heart rate of patients was significantly lower at the 2nd and 3rd 24 h post-injury (with t values of 7.53 and 7.78, respectively, P<0.01), and the hematocrit of patients decreased significantly only at the 3rd 24 h post-injury (t=15.55, P<0.01); the changes of CVP, ScvO2, MAP and heart rate of patients at the 2nd and the 3rd 24 h post-injury, and HCT of patients at the 3rd 24 h post-injury, in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of -12.25, -10.24, -8.99, 9.42, -8.83, -7.53, -11.57, 10.44, and 12.91, respectively, P<0.01). Compared with those of patients in IA group, the rehydration coefficient of patients in CA group was significantly higher only at the 3rd 24 h post-injury (t=5.60, P<0.05), blood lactate value of patients in CA group was significantly lower at the 1st and 2nd 24 h post-injury (with t values of 4.32 and 14.52, respectively, P<0.05 or P<0.01), the hourly urine output of patients in CA group increased significantly at the 1st, 2nd, and 3rd 24 h post-injury (with t values of 24.65, 13.12, and 5.63, respectively, P<0.05 or P<0.01). Compared with the those of patients at the 1st 24 h post-injury, the rehydration coefficient of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 33.98 and 36.91, respectively, P<0.01), the blood lactate values of patients in IA group decreased significantly at the 2nd and the 3rd 24 h post-injury (with t values of 8.20 and 11.68, respectively, P<0.01), and the hourly urine output of patients in IA group was significantly increased at the 2nd and the 3rd 24 h post-injury (with t values of -3.52 and -5.92, respectively, P<0.01); the changes of rehydration coefficients and blood lactate values of patients at the 2nd and the 3rd 24 h post-injury in comparison with those of patients at the 1st 24 h post-injury in CA group were similar to those of patients in IA group (with t values of 35.64, 33.64, 9.86, and 12.56, respectively, P<0.01), but hourly urine output of patients in CA group increased significantly only at the 3rd 24 h compared with that of patients at the 1st 24 h post-injury (t=-3.07, P<0.01). Adverse reactions such as hypotension, nausea, vomiting, dizziness, bradycardia, and pruritus occurred rarely in patients of the 2 groups, and none of the patients had skeletal muscle tonicity, respiratory depression, or drug addiction. The incidence of adverse reactions of patients in CA group was similar to that in IA group (χ2=0.08, P>0.05). Conclusions: Continuous goal-directed analgesia can effectively relieve pain and improve vital signs of patients with large burns. Meanwhile it has little impact on volume load, which can assist in correcting ischemia and hypoxia during the shock period and help patients get through the shock period smoothly.

Clinical research and application of preemptive analgesia in dental treatment / 中华口腔医学杂志

Preemptive analgesia refers to the use of analgesics or regional nerve block in advance of nerve conduction changing or nerve remodeling caused by traumatic stimulation, so as to achieve better postoperative pain relief and to prevent postoperative pain hypersensitivity. Preemptive analgesia minimizes or prevents postoperative pain by reducing peripheral and central sensitization, which thereby limit the pain cascade. This paper briefly introduces the mechanism and methods of preemptive analgesia, as well as its application and research progress in the field of oral treatment. With the increased requirements for comfortable medical treatments and popularization of multimodal analgesia in pain management of oral surgery, preemptive analgesia will be more widely studied and applied in oral diagnosis and treatment.

A prospective randomized controlled study on the effects of compound analgesia in ultra-pulsed fractional carbon dioxide laser treatment of post-burn hypertrophic scars in children / 中华烧伤杂志

Objective: To investigate the effects of compound analgesia on ultra-pulsed fractional carbon dioxide laser (UFCL) treatment of post-burn hypertrophic s in children. Methods: A prospective randomized controlled study was conducted. From April 2018 to March 2020, 169 pediatric patients with post-burn hypertrophic s admitted to the First Affiliated Hospital of Air Force Medical University were randomly divided into general anesthesia alone group (39 cases, 19 males and 20 females, aged 35 (21, 48) months), general anesthesia+lidocaine group (41 cases, 23 males and 18 females, aged 42 (22, 68) months), general anesthesia+ibuprofen suppository group (41 cases, 25 males and 16 females, aged 38 (26, 52) months), and three-drug combination group with general anesthesia + lidocaine+ibuprofen suppository (48 cases, 25 males and 23 females, aged 42 (25, 60) months), and the pediatric patients in each group were treated with corresponding analgesic regimens when UFCL was used to treat s, and the pediatric patients were given comprehensive care throughout the treatment process. The pain degree of pediatric patients scar was evaluated by facial expression,legs,activity,cry,and consolability (FLACC) of children's pain behavior scale at 0 (immediately), 1, 2, and 4 h after awakening from the first anesthesia, respectively. At 4 h after awakening from the first anesthesia of postoperative pain assessment, the self-made analgesia satisfaction questionnaire was used to evaluate the satisfaction for the analgesic effect of the pediatric patients or their families, and the satisfaction rate was calculated. Within 2 h after the first operation, the occurrences of adverse reactions of the pediatric patients, such as nausea and vomiting, headache, dizziness, drowsiness, etc, were observed and recorded. Before the first treatment and 1 month after the last treatment, the Vancouver scar scale (VSS) was used to evaluate the pediatric patients scar, and the difference value between the two was calculated. Data were statistically analyzed with least significant difference test, Kruskal-Wallis H test, chi-square test and Fisher's exact probability test. Results: At 0 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group (P<0.01). The FLACC scores of the pediatric patients in anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than that in general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 1 and 2 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were both significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 4 h after awakening from the first anesthesia, the FLACC scores of the pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01). At 4 h after awakening from the first anesthesia, the satisfactions rate with the analgesic effect in the four groups of pediatric patients or their families were 79.49% (31/39), 85.37% (35/41), 87.80% (36/41), and 97.92% (47/48), respectively. The satisfaction rate of the pediatric patients in three-drug combination group was significantly higher than those in general anesthesia alone group, general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group. Within 2 h after the first operation, there was no significant difference in the overall comparison of adverse reactions such as nausea and vomiting, headache, dizziness, and drowsiness of pediatric patients among the 4 groups (P>0.05). The VSS scores of pediatric patients before the first treatment, 1 month after the last treatment, and and the difference value between the two in the 4 groups were not significantly different (P>0.05). Conclusions: Three-drug combination for analgesia has a good effect in the treatment of hypertrophic scars after burn in pediatric patients with UFCL. Pediatric patients or their families are highly satisfied with the effect, and the treatment effect and incidence of adverse reactions are similar to other analgesic regimens, so it is recommended to be promoted in clinical practice.

Using a consensus acupoints regimen to explore the relationship between acupuncture sensation and lumbar spinal postoperative analgesia: A retrospective analysis of prospective clinical cooperation / 中西医结合学报

OBJECTIVE@#This study evaluated the effectiveness of acupuncture treatment on postoperative pain in patients with degenerative lumbar spine disease, and explored the relationship between the postoperative analgesic effect of acupuncture and the sensation of acupuncture experienced by the patients.@*METHODS@#This retrospective study analyzed the medical records of 97 patients who had undergone an operation by the same surgeon due to degenerative lumbar disease. These patients were divided into acupuncture group (n = 32), patient-controlled analgesia (PCA) group (n = 27), and oral analgesia group (n = 38) according to the different postoperative analgesic methods. During their hospitalization, patients completed daily evaluations of their pain using a visual analogue scale (VAS), and injection times of supplemental meperidine were recorded. Also, the Chinese version of the Massachusetts General Hospital Acupuncture Sensation Scale (C-MASS) was used in the acupuncture group.@*RESULTS@#Each of the three treatment groups showed significant reductions in postoperative pain, as shown by reduced VAS scores. The acupuncture group, however, had less rebound pain (P < 0.05) than the other two groups. Both the acupuncture and PCA groups experienced acute analgesic effects that were superior to those in the oral analgesia group. In addition, the higher the C-MASS index on the second day after surgery, the lower the VAS score on the fourth day after surgery. There was also a significant difference in the "dull pain" in the acupuncture sensation.@*CONCLUSION@#The results demonstrated that acupuncture was beneficial for postoperative pain and discomfort after simple surgery for degenerative spinal disease. It is worth noting that there was a disproportionate relevance between the patient's acupuncture sensation and the improvement of pain VAS score.

OBJECTIVE@#To compare the analgesic effects of two types of spinal manipulation (SM) in acute lumbar radiculopathy (ALR) model rats induced by self-transplantation of autologous nucleus pulposus (ANP), and clarify the therapeutic mechanism.@*METHODS@#Totally 108 male Sprague-Dawley rats were randomly divided into 6 groups by a random number table (18 rats in each group), including a blank group with no interference, a sham operation group with a surgery by making a local soft tissue incision on the left side of L5-6 vertebral segment, a model group with ALR of L5 extraforaminal nerve by ANP self-transplantation without other interference, a sham manipulation (SMA) group with simulating physical rotation, as well as a mobilization (MOB) group with simulating low-velocity and variable-amplitude rotation and a manipulation (MAN) group with simulating high-velocity and low-amplitude rotation. The interventions in SMA, MOB, and MAN groups started 1 day after modeling followed by another 5 treatments at days 3, 5, 8, 10 and 12. Rats in the other 3 groups did not receive any special intervention. Behavioral pain tests of 50% mechanical pain withdrawal threshold (50% PWT) and paw withdrawal latency (PWL) were conducted 1 day before operation followed by another 10 tests on days 1-7, 10, 12 and 14. Immunohistochemical expression of nitric oxide synthase (NOS) was investigated on days 5 and 12 after operation.@*RESULTS@#After 3 experimental SM interventions, 50% PWT and PWL were higher in the MAN group than the SMA group on days 6 and 7, and higher on days 10, 12 and 14 postoperatively (P<0.05 or P<0.01), while the same indices were significantly higher in the MOB group than MAN group on days 1-4 (P<0.05 or P<0.01). The expression of NOS was lower in the MAN and MOB groups than SMA group on day 12 postoperatively (P<0.01).@*CONCLUSIONS@#Both manipulation and mobilization produced better results than sham interference in relieving pain by reducing neuroinflammation possibly. At the early period, compared with manipulation, mobilization presented less sensitive response to pain until later visit. SM may inhibit the overexpression of NOS, thereby alleviating severe radiculopathy.

Effect of sequential sedation and analgesia in preventing delirium and withdrawal symptoms in children after ventilator weaning / 中国当代儿科杂志

OBJECTIVES@#To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning.@*METHODS@#A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning.@*RESULTS@#There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01).@*CONCLUSIONS@#Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

Mechanism of dexmedetomidine preconditioning on spinal cord analgesia in rats with functional chronic visceral pain

Purpose: To analyze the effect and mechanism of dexmedetomidine (DEX) analgesia pretreatment on functional chronic visceral pain in rats. Methods: Rats were divided into six groups: W1, W2, W3, W4, W5, and W6. The behavioral changes and electrophysiological indexes of rats in each group before and after DEX treatment were detected. Results: The levels of abdominal withdrawal reflex (AWR) in W5 and W6 groups were significantly lower than those in group W3, while the levels of thermal withdrawal latency (TWL) and mechanical withdrawal threshold (MWT) were significantly higher than those in group W3 (p < 0.05). The electromyographic signals of W1, W5, and W6 groups showed little fluctuation, while those of groups W2, W3, and W4 showed obvious fluctuation. TLR4 mRNA expression, IRF3, P65, and phosphorylation levels in W4, W5, and W6 groups were significantly lower than those in group W2 (p < 0.05). Conclusions: Dexmedetomidine epidural anesthesia pretreatment could significantly inhibit visceral pain response in rats with functional chronic visceral pain, and its mechanism was related to the activation of TLR4 in spinal dorsal horn tissue of rats and the activation inhibition of IRF3 and P65 in the downstream key signals.

The analgesic effect of preventive administration of meloxicam in calves submitted to hot-iron dehorning / Efeito analgésico da administração preventiva de meloxicam em bezerros submetidos à descorna com ferro quente

Dehorning is a zootechnical practice that causes severe pain in cattle. Although there are several studies evaluating the effects of analgesics in calf dehorning, none of them used validated pain assessment instruments. We evaluated the analgesic effectiveness of meloxicam administered before dehorning, compared to a control group, using the Unesp-Botucatu, numerical, simple descriptive, and visual analogue scales for pain assessment before and 4, 8, and 24 hours after the dehorning in 44 female calves. All calves received 0.04 mg/kg of xylazine IM 20 minutes before dehorning and local anesthetic block with 2% lidocaine with a vasoconstrictor. Calves were divided into two groups: without (GX; n = 22) or with 0.5 mg/kg of meloxicam (GXM; n = 22) administered intravenously before the procedure. Dehorning was performed through the section of the base of the horn bud, followed by thermocautery disbudding. For comparisons over time, mixed linear or generalized mixed linear model were used. The interaction between groups and study phases was used as fixed effects and each calf as a random effect. Bonferroni post hoc test was used. There was an increase in the pain scores at 4h compared to baseline in both groups (GX and GXM) for the four scales. The scores at 4h were higher in GX compared to GXM for all scales. Meloxicam reduced, but did not eliminate, behavioral expressions of pain in calves submitted to hot-iron dehorning. Therefore, it should be included in the analgesic protocol to improve welfare in calves undergoing dehorning.

A descorna é uma prática zootécnica que causa dor intensa em bovinos. Há na literatura diversos estudos sobre os efeitos de analgésicos para mitigar a dor frente a descorna, mas nenhum usando escalas validadas. Avaliamos a eficácia do meloxicam administrado previamente à descorna, comparado a um grupo controle, utilizando-se as escalas Unesp-Botucatu, numérica, simples descritiva e analógica visual para avaliação da dor antes e 4, 8 e 24 horas após a descorna em 44 bezerros fêmeas tratadas com 0,04 mg/kg de xilazina IM 20 minutos antes da descorna e bloqueio anestésico local com lidocaína a 2% com vasoconstritor. Os bezerros foram alocados em dois grupos: sem (GX; n=22) ou com 0.5 mg/kg de meloxicam (GXM; n=22) administrado por via intravenosa antes do procedimento. Realizou-se a descorna por secção da base do botão cornual seguido de termocauterização. Para as comparações ao longo do tempo, empregou-se o modelo linear ou linear misto. Considerou-se a interação entre grupos e momentos como efeito fixo e cada bezerro como efeito aleatório. As alterações foram inferidas de acordo com o pós-teste de Bonferroni. Para as quatro escalas houve aumento dos escores às 4h comparado ao basal em ambos os grupos (GX e GXM). Os escores de todas as escalas às 4h foram maiores em GX que em GXM. O meloxicam reduziu, mas não aboliu, a expressão comportamental da dor em bezerros submetidos à descorna com ferro quente, o que sugere o uso de terapia antálgica multimodal para realizar tal procedimento e garantir o bem-estar animal.

Riesgo de la prescripción de opioides para el manejo del dolor / Risk of Opioid Prescriptions for Management of Pain / Risco de prescrição de opioides para o tratamento da dor

actualmente existe una intensa prescripción de opioides para el manejo de todo tipo de dolor a nivel clínico, razón por la cual es importante considerar los posibles daños derivados de esta actividad, tales como tolerancia, adicción, dependencia y sobredosis. La medicación de opiáceos o sus derivados de manera irracional para el manejo del dolor agudo o crónico puede ser la puerta de entrada a las drogodependencias. Muchos adictos a opiáceos informaron haber estado expuestos por primera vez a los opioides a través de una prescripción médica para el tratamiento del dolor. Por ello, es importante evaluar por parte de los profesionales de la salud el uso a largo plazo de estos medicamentos para el manejo del dolor, porque estudios han evidenciado una relación entre el uso clínico y la dependencia de estos, sobre todo en adolescentes y adultos jóvenes sin experiencia en opiáceos que fueron sometidos a procedimientos quirúrgicos y dentales.

Currently, opioids for managing all types of pain are increasingly prescribed at the clinical level, which is why it is important to consider the potential harms derived from this practice, such as tolerance, addiction, dependence, and overdose. Irrational medication of opioids or opioid derivatives for acute or chronic pain management can be the gateway to drug dependence. Many opioid addicts reported first being exposed to opioids after receiving a physician's prescription for pain management. Therefore, health professionals need to evaluate the long-term use of these medications to manage pain because studies have shown a relationship between clinical use and opioid dependence, especially in adolescents and young adults who had never received opioid therapy and who underwent surgical and dental procedures

Atualmente existe uma intensa prescrição de opioides para o manejo de todos os tipos de dor em nível clínico, por isso é importante considerar os possíveis danos decorrentes dessa atividade, como tolerância, adição, dependência e overdose. A medicação de opiáceos ou seus derivados de forma irracional para o manejo da dor aguda ou crônica pode ser a porta de entrada para a adição a drogas. Muitos dependentes de opioides relataram ter sido expostos a opioides pela primeira vez por meio de uma receita médica para o tratamento da dor. Por esse motivo, é importante que os profissionais de saúde avaliem o uso prolongado desses medicamentos para o manejo da dor, pois estudos têm mostrado relação entre o uso clínico e a dependência dos mesmos, principalmente em adolescentes e adultos jovens sem experiência com opioides que foram submetidos a procedimentos cirúrgicos e odontológicos

CONCLUSION. The prevalence of pressure injuries remains within international accepted standards, their frequency and stages are similar to other reports.

Intravenous lidocaine infusion for the treatment of acute pain in the pediatric intensive care unit: case series / Infusión de lidocaína endovenosa para el tratamiento de dolor agudo en la unidad de cuidado intensivo pediátrico: serie de casos

Abstract Introduction: The use of intravenous lidocaine infusion has increased over the past decade as part of a multimodal approach to analgesia in adults; however, information about its safety and tolerability in the pediatric population is limited. Methods: Acute pain management using lidocaine infusion in eleven patients treated in the pediatric intensive care unit. Results: Five cases of postoperative abdominal pain and six cases of non-operative abdominal pain. Two cases were cancer patients affected by neutropenic colitis. Analgesic control achieved was good. Conclusion: Lidocaine infusions are apparently a safe option for the management of acute pain, either post-operative or not, in the pediatric population.

Resumen Introducción: El uso de la infusión de lidocaína endovenosa ha aumentado en la última década como parte de un enfoque analgésico multimodal en los adultos; sin embargo, se dispone de información limitada sobre su seguridad y tolerabilidad en la población pediátrica. Métodos: Se presentan once casos de manejo de dolor agudo con lidocaína en infusión tratados en unidad de cuidado intensivo pediátrico. Resultados: Cinco casos fueron postoperatorio abdominal y seis casos tenían dolor abdominal no postoperatorio. Dos pacientes tenían cáncer y cursaban con colitis neutropénica. El control analgésico alcanzado fue bueno. Conclusión: Las infusiones de lidocaína parecen ser una opción segura para el manejo del dolor agudo ya sea posquirúrgico o no en la población pediátrica.

Continuous erector spinae plane block at lumbar level for relief of severe pain due to hip fracture: case series / Bloqueo continuo del plano erector de la espina lumbar para manejo del dolor severo por fractura de cadera: serie de casos

Abstract Introduction Hip fracture pain is frequently acute and disabling and increases perioperative complications in the patient; hence it requires a multimodal analgesia approach. This case series describes the continuous erector spinae plane block at the lumbar level for hip fracture analgesia. Methods A search was conducted of patients with hip fracture referred to the pain service of Hospital Universitario San Vicente Fundación (HUSVF) from August 2019 to March 2020, who had undergone continuous erector spinae plane block as part of their analgesic regimen. Results A total of 6 patients, 4 females and 2 males with an average age of 75 years were identified. A reduction in pain intensity from acute to mild or absent was observed in every case, up to 24 hours after the initial injection. 66 % experienced a relapse of severe pain after 24 hours and 2 patients the catheter functionality failed after 24 hours. One patient underwent dermatome pinprick assessment. Conclusions The continuous erector spinae plane block with a single injection provided analgesic efficacy similar to other single injection peripheral blocks, although continuous analgesia for more than 24 hours was not achieved. Some variations in the block technique described may improve the analgesic effectiveness in patients with hip fracture pain.

Resumen Introducción El dolor de la fractura de cadera suele ser fuerte e incapacitante y aumenta las complicaciones perioperatorias en el paciente, lo que hace indispensable el enfoque de analgesia multimodal. En esta serie de casos se describe la experiencia del bloqueo continuo del plano erector de la espina a nivel lumbar para analgesia en fractura de cadera. Métodos Se realizó una búsqueda de los pacientes con fractura de cadera remitidos al servicio de dolor del Hospital Universitario San Vicente fundación (HUSVF) desde agosto de 2019 hasta marzo de 2020, a quienes se les realizó bloqueo continuo del plano erector de la espina como parte de su esquema analgésico. Resultados Se encontraron 6 pacientes, 4 mujeres y 2 hombres, con una edad promedio de 75 años. Se observó reducción de la intensidad del dolor de fuerte a leve o ausente en todos los casos hasta las 24 horas posteriores a la inyección inicial. El 66 % tuvo recaída del dolor fuerte posterior a las 24 horas y en 2 pacientes no se logró funcionalidad del catéter por más de 24 horas. En un paciente se hizo evaluación dermatómica por pinprick (prueba de pinchazo). Conclusiones El bloqueo continuo del plano erector de la espina con inyección única ofreció eficacia analgésica similar a otros bloqueos periféricos en inyección única, aunque no se logró analgesia continua con el catéter por más de 24 horas. Ciertas variaciones en la técnica del bloqueo descrita podrían mejorar la efectividad analgésica en pacientes con dolor por fractura de cadera.
