Cambios Hemodinámicos Asociados a Exodoncias de Terceros Molares Inferiores con el Uso de Articaína 4 % y/o Lidocaína 2 %: Una revisión sistemática / Hemodynamic Changes Associated with Lower Third Molar Extractions with the Use of Articaine 4 % and/or Lidocaine 2 %: A systematic Review

La exodoncia de los terceros molares inferiores es uno de los procedimientos clínicos más comunes en el cual el control del dolor mediante el bloqueo anestésico del nervio alveolar inferior, bucal y lingual resulta ser fundament al y la manera más común de hacerlo es mediante la infiltración de soluciones de anestesia local. Entre ellos la lidocaína y articaína son algunos de los más comunes y pueden estar asociado a vasoconstrictores como la epinefrina que puede provocar aumento de la presión arterial y frecuencia cardíaca razón por la cual se hace necesario la monitorización de cambios hemodinámicos durante la cirugía. Describir los cambios hemodinámicos asociados al uso de lidocaína al 2 % y/ o articaína al 4 % en la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en relación a distintos tiempos operatorios. Se realizó una revisión sistemática en las bases de datos de PubMed, SCOPUS, Web of Science y Sciencedirect. Se analizaron 7 ensayos clínicos controlados en los que utilizaron articaína al 4 % y/o lidocaína al 2 % con epinefrina al 1:100,000 y/o 1:200,000 en volúmenes de 1,8 a 5,4 mL, en los cuales evaluaron la presión sistólica y diastólica, frecuencia cardiaca y saturación parcial de oxígeno en distintos tiempos de la cirugía. Si bien hubo cambios en PAS, PAD, FC y SPO2, todas se mantuvieron dentro de rangos normales bajo el uso de articaína al 4 % y lidocaína al 2 % con epinefrina 1:100,000 y/o 1:200,000 a volúmenes de 1,8 a 5,4mL medidas a distintos tiempos operatorios.

The extraction of lower third molars is one of the most common clinical procedures in which pain control through anesthetic blockade of the lower alveolar, buccal and lingual nerves turns out to be essential and the most common way to do it is through the infiltration of solutions of local anesthesia. Among them, lidocaine and articaine are some of the most common and may be associated with vasoconstrictors such as epinephrine, which can cause an increase in blood pressure and heart rate, which is why it is necessary to monitor hemodynamic changes during surgery. To describe the hemodynamic changes associated with the use of 2 % lidocaine and/or 4 % articaine in systolic and diastolic pressure, heart rate and partial oxygen saturation in relation to different operative times. A systematic review was carried out in the PubMed, SCOPUS, Web of Science and Sciencedirect databases. Seven controlled clinical trials were analyzed in which 4 % articaine and/or 2 % lidocaine were used with epinephrine at 1:100,000 and/or 1:200,000 in volumes of 1,8 to 5,4 mL, in which systolic pressure was evaluated. and diastolic, heart rate and partial oxygen saturation at different times of surgery. Although there were changes in SBP, DBP, HR and SPO2, all remained within normal ranges under the use of 4 % articaine and 2 % lidocaine with epinephrine 1:100,000 and/or 1:200,000 at volumes of 1,8 to 5 .4mL measured at different operative times.

Local Anaesthetics Combined with Vasoconstrictors in Controlled Hypertensive Patients Undergoing Dental Procedures: Systematic Review and Meta-Analysis / Uso de Anestésicos Locales con Vasoconstrictor en Pacientes con Hipertensión Controlada Durante la Atención Odontológica: Una Revisión Sistemática y Metaanálisis

The aim of this systematic review is to assess the safety of local anaesthetics (LA) combined with vasoconstrictors (VC) for patients with controlled hypertension undergoing dental procedures. A comprehensive search strategy were used to identify all relevant randomized controlled trials (RCTs) that evaluated the effect of LA combined with VC. All searches covered the period from 1990 to February 2021. We performed a meta-analysis using random-effect models and assessed overall certainty in evidence using GRADE approach. Our search strategy yielded 1262 references. Finally, seven randomised trials were included, but only three were included in the meta-analysis. The use of LA with VC may result in little to no difference in the heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), but the certainty of the evidence was assessed as low. Death, stroke, acute myocardial infarction, need for hospitalization, pain and bleeding were not reported by the included studies. The hemodynamic changes using VC do not imply an increased risk of occurrence of adverse cardiovascular events. The use of VC could even be recommendable considering their multiple advantages.

El objetivo de esta revisión sistemática es evaluar la seguridad del uso de anestésicos locales (AL) combinados con vasoconstrictor (VC) en pacientes con hipertensión controlada durante procedimientos dentales. Se realizó una estrategia de búsqueda para identificar todos los estudios clínicos aleatorizados (ECA) relevantes que evaluaban el efecto del AL combinado con VC. Todos los estudios fueron del periodo entre 1990 a febrero del 2021. Se realizó un meta-análisis usando modelos de efecto aleatorizado y una revisión de la certeza de la evidencia usando el método GRADE. Nuestra estrategia de búsqueda arrojó 1262 referencias. Finalmente, siete estudios clínicos aleatorizados fueron incluidos, de los cuales tres fueron incluidos en el meta-análisis. El uso de AL con VC produce una pequeña a ninguna diferencia en el pulso cardiaco, presión sistólica y diastólica, pero la certeza de la evidencia fue baja. Muerte, infarto agudo al miocardio, accidente cerebrovascular, necesidad de hospitalización, dolor y hemorragia no fueron reportados en los estudios incluidos. Los cambios hemodinámicos en el uso de VC no implican un aumento de riesgo de ocurrencia de efectos adversos cardiovasculares. El uso de VC puede ser recomendable considerando sus múltiples ventajas.

Ultrasound-Guided Continuous Thoracic Paravertebral Block Improves Patient's Quality of Recovery After Open Hepatectomy: A Randomized, Double-Blind, Placebo-Controlled Trial / 中国医学科学杂志(英文版)

Background Ultrasound-guided continuous thoracic paravertebral block can provide pain-relieving and opioid-sparing effects in patients receiving open hepatectomy. We hypothesize that these effects may improve the quality of recovery (QoR) after open hepatectomy. Methods Seventy-six patients undergoing open hepatectomy were randomized to receive a continuous thoracic paravertebral block with ropivacaine (CTPVB group) or normal saline (control group). All patients received patient-controlled intravenous analgesia with morphine postoperatively for 48 hours. The primary outcome was the global Chinese 15-item Quality of Recovery score on postoperative day 7, which was statistically analyzed using Student's t-test. Results Thirty-six patients in the CTPVB group and 37 in the control group completed the study. Compared to the control group, the CTPVB group had significantly increased global Chinese 15-item Quality of Recovery scores (133.14 ± 12.97 vs. 122.62 ± 14.89, P = 0.002) on postoperative day 7. Postoperative pain scores and cumulative morphine consumption were significantly lower for up to 8 and 48 hours (P < 0.05; P = 0.002), respectively, in the CTPVB group. Conclusion Perioperative CTPVB markably promotes patient's QoR after open hepatectomy with a profound analgesic effect in the early postoperative period.

Analgesic effect of ropivacaine after arthroscopic reconstruction of the ligament in athletes / Efeito analgésico da ropivacaína após reconstrução artroscópica do ligamento em atletas / El efecto de la ropivacaína en el dolor después de la reconstrucción artroscópica de ligamentos de un atleta

ABSTRACT After arthroscopic ligament reconstruction, athletes still need to go through a postoperative rehabilitation training period and suffer the possible pain that can go from moderate to severe. Commonly used analgesic medications, ropivacaine and fentanyl have the effect of relieving athletes' pain. To study the analgesic effect of ropivacaine on arthroscopic reconstruction of the knee ligament, the steps of reconstruction and pharmacology of ropivacaine were first introduced. Next, the analgesic effects of ropivacaine and fentanyl in 86 athletes were compared on muscle strength recovery, patient satisfaction, and pain score. The results showed that the satisfaction of patients with ropivacaine was 95.35%, and the incidence of postoperative adverse reactions was only 9.30%. These results indicate that ropivacaine has a better analgesic effect in arthroscopic reconstruction of the knee ligament in athletes, which is suitable for postoperative rehabilitation.

Safety of local anesthetics

Abstract Local anesthetics are essential medications for the conduction of dermatological procedures. They stop the depolarization of nerve fibers and are divided into two main categories, the amide and ester types. Systemic toxicity with reflex on the central nervous and cardiovascular systems is their most feared adverse reactions, and the anaphylactic reaction is the most concerning one. Although potentially fatal, these events are extremely rare, so local anesthetics are considered safe for use in in-office procedures.

The myofascial component of the pain in the painful shoulder of the hemiplegic patient

OBJECTIVES: Poststroke shoulder pain occurs very frequently and compromises function and quality of life. Because treatment depends on a multidisciplinary approach, it is desirable to optimize effectiveness. Myofascial pain syndrome is defined by the presence of trigger points that can also be found in spastic stroke patients. The aim of this study was to evaluate the frequency of myofascial pain in the shoulder girdle muscles in patients with poststroke shoulder pain and to document the clinical and functional results obtained with specific treatment for this condition. METHODS: Spastic stroke hemiplegic patients undergoing rehabilitation at the Rehabilitation Center of the Hospital das Clínicas of the Ribeirão Preto Medical School of the University of São Paulo were evaluated regarding the intensity and characteristics of shoulder pain, previous therapeutic interventions, shoulder goniometry and the presence of trigger points. Patients underwent trigger point blockade by intramuscular infiltration of 1% lidocaine. The evaluation and treatment procedures were repeated in the subsequent 3 weeks as long as the pain intensity was greater than 5 on a visual analog scale (VAS). In the fourth week, the evaluation procedures were repeated. Patients who were in a multiprofessional rehabilitation program were instructed to continue the treatment, and the others received complementary therapeutic advice if necessary to initiate it. The evaluations were performed at 0, 1, and 3 weeks and after 4 months. RESULTS: Twenty-one patients (13 men; age=67.8±10.2 years; right hemiparesis: 11) participated in the study, and there was a reduction in pain assessed by VAS from baseline (7.6±2.7) to the first week (5.8±3.6; p<0.05) through the end of the third week (5.2±3.5; p<0.05), but not at the end of four months (6.6±2.9; p=0.11). Good responders had significantly lower pain levels after the third week and presented with a larger range of motion for passive abduction by the end of 4 months. These results demonstrate that the myofascial component of pain should be considered in poststroke shoulder pain and that its treatment may be a pathway for the rapid and long-lasting relief of symptoms. CONCLUSION: Trigger point blockade with lidocaine can reduce pain perception in spastic hemiplegic shoulder in as much as 50% of stroke survivors for four months.

Posterior quadratus lumborum block for primary total hip arthroplasty analgesia: a comparative study / Bloqueio anestésico do quadrado lombar posterior para analgesia na artroplastia total do quadril primária: estudo comparativo

ABSTRACT Objective To compare analgesia and opioid consumption for patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. Methods The medical records of patients undergoing unilateral total hip arthroplasty between January 1st, 2017 and March 31, 2018 were reviewed, and 238 patients were included in the study. The primary outcome was postoperative opioid consumption in the first 24 postoperative hours. Secondary outcomes were intraoperative, post anesthesia care unit, and 48-hour opioid consumption, postoperative pain Visual Analog Scale scores, and post-anesthesia care unit length of stay. Primary and secondary endpoint data were compared between patients undergoing primary total hip arthroplasty with preoperative posterior quadratus lumborum block with patients who did not receive quadratus lumborum block. Results For the patients who received quadratus lumborum block, the 24-hour total oral morphine equivalent (milligram) requirements were lower (53.82mg±37.41), compared to the patients who did not receive quadratus lumborum block (77.59mL±58.42), with p=0.0011. Opioid requirements were consistently lower for the patients who received quadratus lumborum block at each additional assessment time point up to 48 hours. Pain Visual Analog Scale scores were lower up to 12 hours after surgery for the patients who received a posterior quadratus lumborum block, and the post-anesthesia care unit length of stay was shorter for the patients who received quadratus lumborum block. Conclusion Preoperative posterior quadratus lumborum block for primary total hip arthroplasty is associated with decreased opioid requirements up to 48 hours, decreased Visual Analog Scale pain scores up to 12 hours, and shorter post-anesthesia care unit length of stay. Level of evidence: III

RESUMO Objetivo Comparar a analgesia e o uso de opioides em pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e pacientes que não receberam o bloqueio do quadrado lombar. Métodos Revisamos os prontuários de pacientes submetidos à artroplastia total do quadril unilateral entre 1º de janeiro de 2017 e 31 de março de 2018, e 238 pacientes foram incluídos no estudo. O desfecho primário foi o consumo de opioides no pós-operatório nas primeiras 24 horas. Os desfechos secundários foram consumo de opioide no intraoperatório, na sala de recuperação pós-anestésica e nas primeiras 48 horas, escores de Escala Visual Analógica de dor pós-operatória, e tempo de permanência na recuperação pós-anestésica. Os desfechos primário e secundários foram comparados entre os pacientes submetidos à artroplastia total do quadril primária com bloqueio pré-operatório do quadrado lombar posterior e aqueles que não receberam o bloqueio do quadrado lombar. Resultados Para o grupo que recebeu o bloqueio, as doses totais de morfina por via oral em 24 horas foram menores (53,82mg±37,41) em comparação ao grupo sem bloqueio (77,59mg±58,42), com p=0,0011. A utilização de opioides foi consistentemente menor para o grupo que recebeu o bloqueio em cada tempo adicional de avaliação até 48 horas. Os escores da Escala Visual Analógica até 12 horas após a cirurgia para os pacientes que receberam o bloqueio do quadrado lombar posterior e o tempo de permanência na sala de recuperação pós-anestésica foram menores para o grupo que recebeu o bloqueio. Conclusão O bloqueio anestésico do quadrado lombar posterior para artroplastia total do quadril primária está associado à diminuição do uso de opioides nas primeiras 48 horas, diminuição do escore de dor da Escala Visual Analógica em até 12 horas, e menor tempo de permanência na sala de recuperação pós-anestésica.

Introduction: Herpetic gingivostomatitis is an infection caused by herpes simplex virus, which affects mainly children patients, being uncommon this manifestation in adults. It initially appears with prodromal signs and then local signs show up. The treatment for this disease is only supportive, because there is already a peak of viral replication when it was diagnosed. Objectives: To report a case of herpetic gingivostomatitis and to discuss its clinical characteristics and treatment. Case report: The patient looked for clinic care for presenting painful oral lesions with little time of evolution. With no medical history, the patient reported using antibiotics and antifungals. Oroscopy showed multiple coalescing ulcerative lesions affecting the gum tissue, tongue, lips and hard palate. It has been diagnosed clinically as herpetic gingivostomatitis and has been treated with supportive treatment (analgesics, topical anesthetic and chlorhexidine digluconate 0,12 percent). The patient returned after one week with improvement of the condition. Conclusion: The correct diagnosis, through the evident clinical manifestations, prevents the indiscriminate use of antibiotics, leading to better response of the patient(AU)

Introducción: La gingivoestomatitis herpética es una infección causada por el virus herpes simple, que afecta principalmente a los pacientes infantiles, la cual resulta inusual en adultos. Inicialmente surge con señales prodrómicas y solo después se presentan señales locales. El tratamiento para este cuadro es solo de soporte, pues cuando se diagnostica ya hay un pico de replicación viral. Objetivo: informar un caso de gingivoestomatitis herpética y discutir sus características clínicas y tratamiento. Presentación del caso: El paciente buscó atención clínica por presentar dolorosas lesiones bucales con poco tiempo de evolución. Sin historial médico, informó que estaba usando antibióticos y antifúngicos, sin remisión de la condición. En la oroscopia se observaron múltiples lesiones ulcerativas coalescentes que afectan el tejido de la gingiva, la lengua, los labios y el paladar duro. Se ha diagnosticado clínicamente como gingivoestomatitis herpética y se ha tratado con tratamiento de apoyo (analgésicos, anestésicos tópicos y digluconato de clorhexidina al 0,12 por ciento). El paciente regresó después de una semana con una mejoría de la condición. Conclusion es: El correcto diagnóstico, a través de las manifestaciones clínicas evidentes, previene el uso indiscriminado de antibióticos, lo que lleva a una mejor respuesta del paciente(AU)

Hemodynamic Behavior in Third Molar Surgeries Using Lidocaine or Articaine / Comportamiento Hemodinámico en Cirugías de los Terceros Molares Utilizando Lidocaína vs Articaina

SUMMARY: The aim of this research was to assess the hemodynamic variations during the extraction of impacted lower third molars using lidocaine 2 % or articaine 4 %, as local anesthetics. Fourteen patients with a mean age of 22.4 (SD=3.25), were submitted to the bilateral extraction of lower third molars, with an interval of three to four weeks between the two extractions. Systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate and oxygen saturation in the blood were assessed at seven specific time points: baseline; anesthetic puncture; two minutes after anesthesia; osteotomy; suture and five minutes after the procedure had been completed. The statistical analysis involved descriptive analysis, the Shapiro-Wilk test, the Mann-Whitney test, the t-test and the repeated measurements test. No significant differences were found for any of the hemodynamic behavior variables when comparing lidocaine 2 % and articaine 4 %. Significant differences were found between the time points assessed within each group, particularly in relation to the variable heart rate. In the articaine group, systolic blood pressure exhibited a significant decrease five minutes after the procedure. There were no significant variations in hemodynamic behavior between the two different anesthetic groups (articaine 4 % and lidocaine 2 %).

RESUMEN: El objetivo de esta investigación fue evaluar las variaciones hemodinámicas durante la extracción de terceros molares inferiores impactados utilizando lidocaína al 2 % o articaína al 4 %, como anestésicos locales. Catorce pacientes con una edad promedio de 22,4 (SD = 3,25), fueron sometidos a la extracción bilateral de terceros molares inferiores, con un intervalo de tres a cuatro semanas entre las dos extracciones. Se evaluaron la presión arterial sistólica, la presión arterial diastólica, la presión arterial media, la frecuencia cardíaca y la saturación de oxígeno en la sangre, en siete momentos específicos: línea base; punción anestésica; dos minutos después de la anestesia; osteotomía; sutura y cinco minutos después de que el procedimiento fue completado. El análisis estadístico involucró el análisis descriptivo, la prueba de Shapiro-Wilk, la prueba de Mann-Whitney, la prueba t y la prueba de mediciones repetidas. No se encontraron diferencias significativas para ninguna de las variables de comportamiento hemodinámico al comparar lidocaína 2 % y articaína 4 %. Se encontraron diferencias significativas entre los puntos de tiempo evaluados dentro de cada grupo, particularmente en relación con la frecuencia cardíaca variable. En el grupo de articaína, la presión arterial sistólica exhibió una disminución significativa cinco minutos después del procedimiento. No se observaron variaciones significativas en el comportamiento hemodinámico entre los dos grupos anestésicos diferentes (articaína 4 % y lidocaína 2 %).

Postoperative local incision analgesia for acute pain treatment in patients with hepatocellular carcinoma

Summary Objective: The present study aimed to investigate the analgesic effect and safety of using local incision analgesia to treat acute postoperative pain in patients with hepatocellular carcinoma (HCC). Method: A cohort of 60 patients undergoing liver cancer resection was randomly divided into three groups (n=20 per group): local incision analgesia (LIA) group, which received local infiltration with ropivacaine combined with a postoperative analgesia pump; intravenous patient-controlled analgesia (PCA) group, which received fentanyl intravenous analgesia postoperatively; and the control group, which received tramadol hydrochloride injection postoperatively according to the NRS scoring system. The postoperative analgesic effect in each group was compared and tumor recurrence (survival) was analyzed using the Kaplan-Meier method. Results: NRS scores, rate of analgesic usage, ambulation time (h) and intestinal function recovery time (h) were significantly reduced in LIA group compared with the control group at each postoperative time point (6, 12, 24 and 48 hours; p<0.05). Additionally, the NRS scores of LIA patients at 12 hours post-surgery was significantly reduced compared with PCA group (p<0.05), and the occurrence of postoperative adverse events in LIA group was significantly lower than that in PCA group (p<0.05). Survival analysis demonstrated that the mean survival time (tumor recurrence) was significantly increased in LIA group compared with the control group (χ2=4.749; p=0.029). Conclusion: Local incision analgesia improves the analgesic effect, causes fewer adverse reactions and increases postoperative survival time. Our study demonstrated that local incision analgesia is a safe and effective method of postoperative pain management following hepatectomy.

TeleCondutas: hemorroidas / TeleGuides: hemorrhoids

Hemorroidas são coxins vasculares normais do canal anal. São formados por espaços vasculares (sinusoides), tecido elástico e conjuntivo, e músculo liso. Sua função é proteger os esfíncteres anais subjacentes e contribuir para a continência fecal. Reservamos o termo "doença hemorroidária" para quando existem sintomas relacionados à sua presença. É mais prevalente em pessoas com idade entre 45 e 65 anos, tendo como principal causa o esforço evacuatório repetitivo, que determina o estiramento do tecido de sustentação dos plexos. Constipação, esforço evacuatório prolongado e gestação são seus principais fatores de risco. Esta guia apresenta informação que orienta a conduta para casos de hemorroidas no contexto da Atenção Primária à Saúde, incluindo: classificação das hemorroidas, sinais e sintomas, diagnóstico, tratamento da doença hemorroidária na APS, tratamento no serviço especializado, indicação de colonoscopia e encaminhamento para serviço especializado.

Effect of dexmedetomidine on supraclavicular brachial plexus block: a randomized double blind prospective study / 北京大学学报(医学版)

OBJECTIVE@#To evaluate the effect of dexmedetomidine combined with ropivacaine on brachial plexus block in patients scheduled for elective shoulder arthroscopy.@*METHODS@#Ninety patients with American Society of Anesthesiologists (ASA) I or II, scheduled for elective shoulder arthroscopy, were randomly divided into three groups. In group R (n=30), the patients were given 10 mL of 0.375% ropivacaine in branchial plexus block (interscalene approach guided by ultrasound), in group D1 (n=30), the patients were given 10 mL of 0.375% ropivacaine (interscalene approach guided by ultrasound) + dexmedetomidine 0.2 μg/(kg×h) (intravenous pump infusion), and in group D2 (n=30), the patients were given 10 mL of 0.375% ropivacaine (interscalene approach guided by ultrasound) + dexedetomidine 0.7 μg/(kg×h) (intravenous pump infusion). To evaluate the effect of brachial plexus block before general anesthesia. Group D1 and group D2 were given dexmedetomidine intravenously for 1.0 μg/kg during 10 min, then the drug was pumped by 0.2 μg/(kg×h) and 0.7 μg/(kg×h) respectively until 30 min before the operation finished. Changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and before anesthesia (T0), 10 min (T1), 30 min (T2) after giving dexmedetomidine, discontinue medication (T3), after operation (T4), and extubation (T5) were investigated. Motor and sensory block onset times, block durations, and duration of analgesia were recorded. The scores of pain after operation and the adverse effects of shiver, hypopiesia, drowsiness, and blood loss were recorded during operation.@*RESULTS@#Compared with group R, the duration of analgesia and duration of sensory block in group D1 and group D2 were significant longer (P<0.01), there was no significant difference between groups D1 and D2 (P>0.05). Compared with group R, at each time point of T1-T5, the heart rate and systolic blood pressure in group D1 and group D2 were significantly decreased (P<0.01). Compared with D1 group, the incidence of hypotension and bradycardia in group D2 were significantly different (P<0.05).@*CONCLUSION@#Intravenous dexmedetomidine could prolong the duration of analgesia time and sensory block within the brachial plexus block, inhibiting the stress response during arthroscopic shoulder surgery. Compared with high-dose, low-dose can provide safer and better clinical effect and reduce the adverse effects of dexmedetomidine.
