Perineural low dexamethasone dose as adjuvant in supraclavicular brachial plexus block for arteriovenous fistula creation in end stage renal disease: a randomized controlled trial

Abstract Background and aims: Dexamethasone as adjunct to local anesthetic solution improves the quality of brachial plexus block (BPB). However, evidence for its efficacy at low doses (< 4 mg) is lacking. This study was designed to evaluate the duration of analgesia attained with low dose dexamethasone as adjuvant to local anesthetic for creation of arteriovenous fistula (AVF) under BPB. Methods: Sixty-six patients scheduled for AVF creation were randomly allocated to receive either saline (control) or 2 mg dexamethasone, together with 0.5% ropivacaine and 0.2% lignocaine. The primary outcome was duration of analgesia, defined as time from performing the block to the first analgesic request. The secondary outcomes were time from injection to complete sensory block, time from injection to complete motor block, duration of motor block, postoperative analgesic consumption, and fistula patency at three months. Results: All the blocks were effective. In the group that received dexamethasone, the time to first analgesic request was significantly delayed (432 ± 43.8 minutes vs. 386.4 ± 40.2 minutes; p < 0.01). The onset of sensory and motor blockade occurred faster in dexamethasone group and overall analgesic consumption was also reduced. However, dexamethasone addition did not prolong the duration of motor block. There was no statistically significant difference in the patency of fistulas between the two groups at three months. (p = 0.34). Conclusion: Addition of low-dose perineural dexamethasone to local anesthetic solution significantly prolonged the duration of analgesia. Further trials are warranted to compare the adverse effects between dexamethasone doses of 4 mg and lower.

Fixed and on-demand regimens of acetaminophen in periodontal surgery: randomized clinical trial

Aim: to evaluate the clinical efficacy of an acetaminophen analgesic by comparing its prescription in fixed versus ondemand schedules after periodontal surgery. The hypothesis of the study was that the fixed regimen would be more effective than the on-demand regimen for postoperative analgesics following periodontal surgery. Methods: An open randomized clinical trial was conducted. The 68 patients who needed total flap surgery to restore supracrestal tissue attachment or surgical treatment of periodontitis were randomized". Visual Analogue Scale was used to assess pain. The fixed group (n = 34) received 500 mg of acetaminophen every 4 hours for 2 days. The on-demand group (n = 34) was instructed to use the acetaminophen "as needed," at intervals of no less than 4 hours between doses. Ibuprofen was the rescue medication for both groups. Pain scores and medication use were recorded 2, 6, 12, 24 and 48 hours after the surgical procedure. The study was registered at the Brazilian Registry of Clinical Trials under RBR-7wv259. Results: The two groups did not differ in relation to the frequency or the intensity of pain in a 48-hour period (n=20 in the fixed group, and n=22 in the on-demand group), or even in the intention-to-treat (n=34 in each group). Individuals who experienced moderate to severe pain used rescue medication more frequently in both groups. No adverse events were reported. Conclusion: Both regimens were effective in controlling postoperative pain after periodontal surgery

Bloqueio epidural torácico comparado a morfina endovenosa no tratamento da dor na síndrome pós-embolização hepática: ensaio clínico randomizado controlado / Thoracic epidural block compared to intravenous morphine in the treatment of pain in hepatic post-embolization syndrome: a randomized controlled clinical trial

Introdução: A embolização e a quimioembolização transarterial hepática são procedimentos cirúrgicos usados para tratar pacientes com tumores hepáticos de origem primária e metastática, entretanto causam dor importante no período pós-operatório. O objetivo do estudo foi comparar o bloqueio epidural torácico à morfina endovenosa no tratamento da dor na síndrome pós-embolização hepática. Métodos: Foram randomizados 50 casos de pacientes submetidos a embolização transarterial hepática, os quais foram alocados em dois grupos: grupo morfina endovenosa (GV), submetido a uma dose de morfina na sala operatória; e o grupo bloqueio epidural torácico (GE), submetido a bloqueio epidural de injeção única. Todos os pacientes utilizaram analgesia endovenosa controlada pelo paciente no período pós-operatório. Foram analisados no estudo o consumo de morfina endovenosa no período pós-operatório, a dor aferida pela escala numérica verbal (ENV), o tempo de internação hospitalar, a incidência de náuseas, vômitos, prurido, retenção urinária, depressão respiratória e sonolência. Resultados: Não houve diferença do consumo médio de morfina e da ENV no período pós-operatório imediato. No primeiro dia pós-operatório o consumo médio de morfina no GV foi de 6.3 mg vs. 0.45 mg no GE, p < 0.01. A ENV no GV foi de 3.77 vs. 0.82 no GE, p<0.01. O consumo médio de morfina no período pós-operatório no GV foi de 6.91mg vs. 0.5mg no GE, p<0.01. Apenas dois pacientes do GE ficaram internados por mais de um dia, enquanto no GV oito pacientes receberam alta hospitalar a partir do segundo dia pós-operatório, entretanto não houve diferença estatisticamente significativa do tempo de internação hospitalar. Prurido foi observado em 18.2% dos pacientes do GE, e não houve ocorrência no GV, p=0.04. Conclusões: O bloqueio epidural torácico foi superior à morfina endovenosa no tratamento da dor na síndrome pós-embolização hepática.

Background: Hepatic transarterial embolization and chemoembolization are surgical procedures used to treat patients with hepatic tumors of primary and metastatic origin, however they cause significant pain in the postoperative period. The objective of the study was to compare thoracic epidural block with intravenous morphine in the treatment of pain in hepatic post-embolization syndrome. Methods: A total of 50 patients undergoing hepatic transcatheter arterial embolization were randomized and allocated into two groups: intravenous morphine group (IG) underwent to a morphine dose in the operating room; and thoracic epidural block group (EG) underwent to a single-shot epidural injection. All patients used intravenous patient-controlled analgesia (PCA) in postoperative period. Intravenous morphine consumption in the postoperative period, pain measured by the numerical rating scale (NRS), length of hospital stay, nausea, vomiting, pruritus, urinary retention, respiratory depression and drowsiness were analyzed. Results: There was no difference in the mean morphine consumption and NRS in the immediate postoperative (IPO) period. On postoperative day 1, the IG mean morphine consumption was 6.3 mg vs. 0.45 mg in EG, p<0.01. NRS in IG was 3.77 vs. 0.82 in EG, p<0.01. Morphine consumption in post-operative period in IG was 6.91 mg vs. 0.5 mg in EG, p<0.01. Only two patients in the EG were hospitalized for more than one day, while in the GV eight patients were discharged from the second postoperative day, however there was no statistically significant difference in the length of hospital stay. Pruritus was observed in 18.2% of EG patients and none in the IG, p = 0.04. Conclusions: Thoracic epidural block was superior to intravenous morphine in the treatment of pain in hepatic post embolization syndrome.

Efecto placebo en otorrinolaringología: revisión de la literatura / Placebo effect in otorhinolaryngology: a narrative review

Resumen La palabra placebo ha sido usada, indistintamente, para referir a una sustancia o procedimiento que es "inerte" ("placebo") y al efecto que ocurre como consecuencia de la administración de un placebo ("efecto placebo"). El efecto placebo es un fenómeno psicobiológico que ha sido explicado desde el conductismo (condicionamiento clásico), desde fenómenos preconscientes (expectativas o "efecto placebo clásico"), desde el cognitivismo (disonancia cognitiva) y también a nivel neurobiológico. No obstante, los ensayos clínicos abiertos que verifican la respuesta a placebo desafían el mecanismo de la expectativa, dando lugar al análisis bayesiano, que integra sensaciones, experiencias, predicciones y claves del contexto; biológicamente, el efecto placebo no es inerte. Por tanto, el placebo ocupa un lugar relevante en la práctica clínica y en la investigación biomédica. Se realizó una búsqueda sistemática sobre placebo y otorrinolaringología en las bases de datos PubMed/Medline, SciELO y Cochrane Library. Se incluyeron estudios primarios y revisiones sistemáticas de la literatura. En cuanto a intervenciones placebo, la literatura publicada indica mejorías significativas en síntomas nasales y calidad de vida en rinitis alérgica (estacional y perenne) y disminución del dolor posoperatorio en amigdalectomía. En la enfermedad de Méniere, las intervenciones placebo son comparables a las de uso habitual, incluyendo las quirúrgicas. No se encontraron ensayos clínicos abiertos en otorrinolaringología ni evidencia sobre otras patologías del área. Las intervenciones y el efecto placebo abren un campo de investigación y desarrollo en otorrinolaringología que desafía la comprensión actual de las patologías, su funcionamiento, su tratamiento y la relación terapéutica.

Abstract The word placebo has been used interchangeably to refer to a substance or procedure that is "inert" ("placebo") and the effect that occurs as a consequence of its administration ("placebo effect"). The placebo effect corresponds to a psychobiological phenomenon that has been explained from behaviorism (classical conditioning), from preconscious phenomena (expectations or "classical placebo effect"), from cognitivism (cognitive dissonance) and at the neurobiological level as well. Nevertheless, some open-label trials that verify the response to placebo challenge the expectation mechanism, giving rise to Bayesian analysis, which integrates sensations, experiences, predictions and context clues; therefore, biologically, the placebo effect is not inert. The placebo has a relevant place both in clinical practice and in biomedical research. We conducted a systematic search on placebo and otolaryngology in PubMed/Medline, SciELO and Cochrane Library databases. We included primary studies and systematic reviews. Regarding placebo interventions, the available literature points out significant improvements in nasal symptoms and quality of life in allergic rhinitis (seasonal and perennial) and a decrease in post-tonsillectomy pain. In Méniére's disease, placebo interventions have demonstrated to be comparable to treatment-as-usual, including surgical interventions. No open-label clinical trials were found in otolaryngology, as well as no evidence on other diseases in the area. Placebo interventions and their effects open a field of research and development in otolaryngology, challenging the current understanding of pathologies, their functioning, their treatment and the therapeutic relationship.

Assessment of The Addition of Epinephrine to Intra-articular Bupivacaine for the Control of Acute Pain in Patients underwent to Anterior Cruciate Ligament Reconstruction / Avaliação da adição da epinefrina à bupivacaína intra-articular no controle da dor aguda em pacientes submetidos a reconstrução do ligamento cruzado anterior

Abstract Objective To evaluate postoperative pain, using the visual analog scale (VAS), in patients undergoing anterior cruciate ligament reconstruction (ACLR) and receiving intra-articular anesthetic solutions. Methods The present is a randomized clinical trial with a sample of 48 patients divided into 4 groups: Group I (n » 12) - 20 mL of saline solution (control); Group II (n » 12) - 20 mL of 0.5% bupivacaine; Group III (n » 12) - 20 mL of 0.5% bupivacaine þ 0.1 mg of epinephrine; and Group IV (n » 12) - 20 mL of saline solution þ 0.1 mg of epinephrine. These solutions were injected into the knee at the end of the surgery. Pain was assessed using the VAS immediately and 6, 12, 24 and 48 hours after the procedure. Results The VAS scores were highly variable among the groups. A Kruskal-Wallis analysis of variance (ANOVA), considering a level of significance of 5%, revealed that all intra-articular anesthetic solutions influenced the assessment of pain (p » 0.003), and that Group-III subjects presented less postoperative pain. There was no evidence of a higher or lower use of supplemental analgesic agents, or of adverse effects resulting from these anesthetic solutions. Conclusion Bupivacaine combined with epinephrine was the most effective solution for pain control in patients undergoing ACLR, but with no statistically significant differences when compared to Group II (p » 0.547). There was no decrease or increase in the use of supplemental analgesics or in the occurrence of adverse systemic effects (p > 0.05).

Resumo Objetivo Avaliar primariamente a dor pós-operatória, por meio da escala visual analógica (EVA), nos pacientes submetidos a reconstrução do ligamento cruzado anterior (RLCA) que receberam soluções anestésicas intra-articulares (IAs). Métodos Ensaio clínico randomizado com uma amostra de 48 pacientes, divididos em 4 grupos: Grupo I (n » 12) - 20 ml de solução fisiológica (controle); Grupo II (n » 12) - 20 ml de bupivacaína a 0,5%; Grupo III (n » 12) - 20 ml de bupivacaína a 0,5% þ 0,1 mg de epinefrina; e Grupo IV (n » 12) - 20 ml de solução fisiológica þ 0,1 mg de epinefrina, injetados no joelho ao término da cirurgia. A dor foi avaliada pela EVA imediatamente e 6, 12, 24 e 48 horas após o procedimento. Resultados Observou-se grande variabilidade nos resultados da EVA entre os pacientes avaliados em cada grupo. Verificou-se, pela análise de variância (analysis of variance, ANOVA) de Kruskal-Wallis, considerando um nível de 5% de significância, que as soluções anestésicas IAs de cada grupo influenciaram na avaliação da dor desses pacientes (p » 0,003), sendo os do Grupo III os que apresentaram menor dor pósoperatória. Não se evidenciou um maior ou menor consumo de drogas analgésicas suplementares, ou efeitos adversos das decorrentes das soluções empregadas. Conclusão A solução combinada de bupivacaína e epinefrina foi a mais eficaz no controle da dor nos pacientes submetidos a RLCA, mas sem diferenças estatisticamente significativas com relação ao grupo II (p » 0,547).

Anesthetic considerations and postoperative pain management in radical penectomy: Case report / Penectomía radical, consideraciones anestésicas y manejo del dolor postoperatorio: Reporte de un caso

Abstract Radical penectomy (RP) is infrequently performed as it is reserved for specific cases of penile cancer, hence the paucity of reports regarding surgical and anesthetic considerations. Acute postoperative pain, chronic post-surgical pain, concomitant mood disorders as well as a profound impact on the patient's quality of life have been documented. This case is of a patient with diabetes and coronary heart disease, who presented with advanced, over infected penile cancer, depressive disorder and a history of pain of neuropathic characteristics. The patient underwent radical penectomy using a combined spinal-epidural technique for anesthesia. Preoperatively, the patient was treated with pregabalin and magnesium sulphate, and later received a blood transfusion due to intraoperative blood loss. Adequate intra and postoperative analgesia was achieved with L-bupivacaine given through a peridural catheter during one week. Recovery was good, pain was stabilized to preoperative levels and the patient received pharmacological support and follow-up by psychiatry and the pain team.

Resumen La penectomía radical (PR) es una cirugía infrecuente, reservada para casos específicos de cáncer de pene, por lo que hay escasos informes sobre sus consideraciones quirúrgicas y anestésicas. Se ha documentado dolor agudo postoperatorio, dolor crónico posquirúrgico y alteraciones del estado de ánimo concomitantes, así como un profundo impacto en la calidad de vida posterior del paciente. Se presenta el caso de un paciente diabético y cardiópata coronario con cáncer de pene avanzado y sobreinfectado, trastorno depresivo y dolor previo de características neuropáticas, que recibe técnica combinada espinal-peridural para cirugía de penectomía radical. Se le trata también con pregabalina preoperatoria, sulfato de magnesio y transfusión por sangrado quirúrgico. Se otorgó una adecuada analgesia intra y postoperatoria, mediante catéter peridural con L-bupivacaína hasta por una semana. El paciente tuvo una buena recuperación, estabilización del dolor a niveles preoperatorios, controles y apoyo farmacológico por psiquiatría de enlace y equipo del dolor.

Eficácia da terapia de fotobiomodulação em episiotomias / Photobiomodulation therapy efficacy in episiotomies

Introdução: Com a finalidade de evitar e reduzir lesões dos tecidos do canal do parto, a episiotomia pode ser realizada. Contudo, complicações cicatriciais podem ocorrer e resultar em desconfortos e dificuldades nas atividades diárias das parturientes. O uso de fotobiomodulação (FBM) em episiotomia é considerada uma alternativa de método não farmacológico para auxiliar no tratamento e cuidado destas puérperas. Objetivo: Revisar os estudos publicados nos últimos 20 anos sobre o efeito da FBM em episiotomia. Métodos: Revisão sistemática da literatura realizada através de busca digital em artigos publicados em revistas eletrônicas, ensaios clínicos e ensaios clínicos randomizados, entre os anos de 2000 e 2020, nas bases de dados eletrônicas PEDro, PubMed, Science Direct e Bireme. Resultados: Foram verificados estudos com aplicação da FBM para reparo tecidual e analgesia em episiotomia. A partir da análise de estudos metodologicamente mais robustos, a FBM não pareceu apresentar benefícios na aceleração do processo cicatricial, mas alguns resultados positivos para o controle da dor. Conclusão: De acordo com os achados, são necessários mais estudos com adequação de parâmetros e qualidade metodológica para elucidar quais os efeitos do uso da FBM no tratamento de episiotomia. (AU)

Introduction: To avoid and reduce lesions of tissues in the birth canal, an episiotomy can be performed. However, scar complications can occur and result in discomfort and difficulties in daily activities of parturient women. The use of photobiomodulation therapy (PBMT) in episiotomy is considered an alternative non-pharmacological method to assist in treatment and care of these puerperal women. Objective: To review the studies published in the last 20 years on the effect of PBMT on episiotomy. Methods: A systematic review was conducted through the search of articles published in electronic journals, clinical trials, and randomized clinical trials between 2000 and 2020, in the electronic databases PEDro, PubMed, Bireme, Science Direct. Results: Studies with the application of PBMT for tissue repair and analgesia in episiotomy were verified. From the analysis of methodologically robust studies, the PBMT did not represent benefits in accelerating the healing process, but some positive results for pain control. Conclusion: According to the findings, further studies are needed with adequate parameters and methodological quality to elucidate the effects of using PBMT in the treatment of episiotomy. (AU)

Use of gabapentin in management of postoperative pain after crosslinking / Uso da gabapentina no manejo da dor pós-operatória do crosslinking

ABSTRACT Objective: The objective was to evaluate the efficacy of gabapentin in the management of neuropathic pain in patients with keratoconus, who were treated with fast (10 minutes) epi-off corneal crosslinking (CXL). Methods: This was a prospective, double-blind, randomized study. The sample comprised patients with bilateral progressive keratoconus, aged 12 years or older, who underwent a bilateral epi-off corneal CXL (fast - 10 minutes) procedure. One group was given placebo orally, and the other group received gabapentin 600 mg orally, both preoperatively. The visual analogue scale (VAS) was applied to record postoperative pain up to 48 hours after procedure. The study was conducted at the Belotto Stock Centro Oftalmológico, in the city of Joaçaba, Santa Catarina, Brazil, from June 2018 to September 2019. Results: At no point in the study significant differences were observed between groups, in terms of pain intensity measured by means of the VAS questionnaire, or of opioid use (Paco®), though opioid consumption was 21% lower in the group receiving gabapentin. Conclusion: We concluded gabapentin has no efficacy in postoperative pain control after epi-off corneal CXL (fast - 10 minutes). Although there was no statistically significant difference, the group that received gabapentin suffered less pain, resulting in lower opioid consumption. UTN number: U1111-1256-0330.

RESUMO Objetivo: Avaliar a eficácia do uso da gabapentina no manejo da dor neuropática em pacientes portadores de ceratocone submetidos ao tratamento de crosslinking corneano epi-off fast de 10 minutos. Métodos: Tratou-se de pesquisa prospectiva, duplo-cega, randomizada. A amostra foi composta de pacientes com ceratocone progressivo bilateral, a partir dos 12 anos de idade, submetidos ao procedimento de crosslinking corneano acelerado epi-off fast de 10 minutos bilateral. Um grupo recebeu placebo via oral e o outro, gabapentina 600mg, via oral, ambos no pré-operatório. A Escala Visual Analógica foi aplicada para registrar a dor pós-operatória até 48 horas após o procedimento. A pesquisa foi realizada no período de junho de 2018 a setembro de 2019 em um centro oftalmológico. Resultados: Não foram observadas diferenças estatísticas significativas para ambos os grupos, tanto na intensidade da dor medida pela Escala Visual Analógica, como na redução do uso do opioide (Paco®), em qualquer horário analisado durante um período de 48 horas. No entanto, houve redução de 21% no consumo de opioides pelo grupo que fez uso da gabapentina. Conclusão: A gabapentina não demonstrou eficácia no controle da dor no pós-operatório do crosslinking corneano epi-off fast de 10 minutos. No entanto, observou-se que, mesmo não havendo diferença estatisticamente significativa, houve diminuição da dor no grupo em que foi usada a gabapentina, resultando na redução do consumo de opioides. Número UTN: U1111-1256-0330.

Methylene Blue for the Treatment of Health Conditions: a Scoping Review

HIGHLIGHTS This scoping review summarizes the findings of clinical trials using methylene blue (MB) for the treatment of various health conditions. This research method allowed mapping main findings, clarifying research topics, and identifying gaps in the literature.

Abstract studies evaluating effective drugs for health conditions are of crucial importance for public health. Methylene blue (MB) is an accessible synthetic drug that presents low toxicity and has been used in several health areas due to its effectiveness. Objective: this scoping review aims to provide a comprehensive overview of relevant research regarding the use of MB for the treatment of health conditions. Methods: a five-stage framework Arksey and O'maley scoping review was conducted. The literature was searched in Cochrane Library database using Mesh term "methylene blue". Data were collected by two independent reviewers and submitted to descriptive synthesis. Results: The search resulted in 429 records, from which 16 were included after exclusion criteria were applied. The therapeutic use of MB was identified for acute conditions (malaria and septic shock), chronic conditions (discogenic back pain, bipolar disorder, refractory neuropathic pain, and post-traumatic stress disorder), and postoperative care (vasoplegic syndrome, and pain after haemorrhoidectomy, lumbar discectomy, and traumatic thoracolumbar fixation). Conclusion: there is much evidence emerging from clinical trials about the therapeutic use of MB for acute, chronic, and postoperative conditions; however, many gaps were identified, which open further avenues for future research.

Infusión intravenosa de ketamina a bajas dosis durante cirugía de artrodesis de columna. Una estrategia en el manejo del dolor agudo posoperatorio / Intravenous ketamine infusión at low doses during spinal arthodesis surgery. A strategy in acute postoperative pain management

INTRODUCTION: Acute postoperative pain is a complex problem given the pathophysiological characteristics, increasing health costs and complications and hindering recovery[1],[2]. Spinal arthrodesis is one of the most painful surgical procedures, presenting intense and disabling pain[3],[4]. Multimodal analgesia has been the tool with the best results, based on opioids; however, the combined use of drugs and dependence on opiates are important consequences. Therefore, the analgesic behavior during the use of subanesthetic doses of ketamine is described in the patients undergoing this procedure. METHODOLOGY: A prospective case series study was conducted from January-December 2019, with patients undergoing spinal arthrodesis who met the inclusion criteria, at the Hernando Moncaleano Perdomo University Hospital, Neiva. A univariate statistical analysis of all the variables is performed, with a joint interpretation of the results. RESULTS: A total of 17 patients underwent surgery, one of whom was excluded due to complications related to the surgical material. 88% of the patients showed evaluations of mild or absent pain in at least 4 times, with a number of morphine rescues in 24 hours of 1-2 per patient and patient ambulation in 90% on the first day. CONCLUSIONS. Postoperative spinal arthrodesis patients receiving intravenous ketamine infusion-based analgesia at subanesthetic doses showed mild or absent pain scores at almost all times.

INTRODUCCIÓN: El dolor agudo postoperatorio es un problema complejo dada las características fisiopatológicas, aumentando los costos en salud y las complicaciones y dificultando la recuperación[1],[2]. La artrodesis de columna, es uno de los procedimientos quirúrgicos más dolorosos, presentando un dolor intenso e incapacitante[3],[4]. La analgesia multimodal ha sido la herramienta con mejores resultados, tomando como base los opioides; sin embargo, el uso combinado de fármacos y la dependencia a opiáceos son consecuencias importantes. Por lo anterior, se describe el comportamiento analgésico durante el uso de dosis subanestésicas de ketamina en los pacientes llevados a dicho procedimiento. METODOLOGÍA: Se realiza un estudio tipo serie de casos, prospectivo de enero-diciembre de 2019, con los pacientes llevados a artrodesis de columna que cumplieron con los criterios de inclusión en el Hospital Universitario Hernando Moncaleano Perdomo, Neiva. Se realiza un análisis estadístico univariado de la totalidad de las variables, con una interpretación conjunta de los resultados.

CONCLUSIONES: Los pacientes posoperatorios de artrodesis de columna que recibieron analgesia basada en infusión endovenosa de ketamina a dosis subanestésicas mostraron valoraciones de dolor leve o ausente, en casi todos los tiempos.

Revisión de metadona intraoperatoria para el manejo de dolor posquirúrgico / Intraoperative methadone for the management of postsurgical pain a review

Pain management associated with surgery is a constant concern of the health team as well as the patient. Multiple proposals for analgesia have been made in the perioperative context. The use of opioids with rapid effect and easy titration in the intraoperative period are currently frequent; to then perform a postoperative analgesic control with drugs with a longer half-life, usually achieving adequate pain management. However, sometimes the standard analgesic scheme is not enough. The problems associated with this situation have led to the need for high doses of opioids in the postoperative period, with the requirement for monitoring, health personnel, and the adverse effects that these involve. Methadone is a long-acting, rapid-onset opioid, the latter secondary to its long elimination half-life. It is presumed that these characteristics have led patients to report adequate pain management, which has been related to a decrease in the need and dose of rescue opioids, in addition to delaying the requirement of these if necessary during the postoperative. These properties allow methadone to be a potential solution to perioperative pain management.

El manejo del dolor asociado a la cirugía es una preocupación constante del equipo de salud al igual que del paciente. Se han planteado múltiples propuestas de analgesia en el contexto perioperatorio, siendo actualmente frecuente el uso de opioides de rápido efecto y fácil titulación en el intraoperatorio; para luego realizar un control analgésico postoperatorio con fármacos de mayor vida media, logrando habitualmente un manejo adecuado del dolor. Sin embargo, a veces el esquema analgésico estándar no es suficiente. La problemática asociada a esta situación ha llevado a la necesidad de altas dosis de opioides en el posoperatorio, con el requerimiento de monitorización, personal de salud y efectos adversos que estos involucran. La metadona es un opioide de inicio de acción rápido y larga duración, este último secundario a su vida media de eliminación prolongada. Se presume que estas características han logrado que los pacientes reporten un adecuado manejo de su dolor, lo que se ha relacionado a una disminución en la necesidad y dosis de opioides de rescate, además de retrasar el requerimiento de éstos en el caso de ser necesarios durante el postoperatorio. Estas propiedades permiten que la metadona pueda ser una potencial solución al manejo del dolor perioperatorio.

Influência do ProTaper/ProTaper Next, comparado a outros sistemas rotatórios/reciprocantes, no risco e na intensidade da dor pós-operatória após instrumentação endodôntica em pacientes adultos: uma revisão sistemática e metanálise / Influence of ProTaper/ProTaper Next, compared to other rotatory/reciprocating systems, on the risk and intensity of postoperative pain after endodontic instrumentation in adult patients: a systematic review and meta-analysis

Introdução: O sucesso da terapia endodôntica depende não apenas de sua eficácia e conclusão adequada, mas também do mínimo desconforto do paciente. Objetivo: O objetivo dessa revisão sistemática e metanálise é avaliar o risco e a intensidade da dor endodôntica pós-instrumentação em pacientes adultos. Métodos: Uma pesquisa abrangente foi realizada no MEDLINE via PubMed, Scopus, Web of Science, LILACS, BBO e Cochrane Library e SIGLE, sem restrições. Também foram pesquisadas a conferência anual dos resumos da IADR (1990-2016) e o registro de ensaios não publicados e em andamento. As dissertações e teses foram pesquisadas utilizando-se os bancos de dados das dissertações ProQuest e das bases de teses Periódicos Capes. Apenas ensaios clínicos randomizados que compararam o risco ou a intensidade da dor resultante do tratamento endodôntico em pacientes adultos foram incluídos. Resultados: Após a remoção das duplicatas, 827 artigos foram identificados. Após a triagem do título e resumo, restaram 26 estudos, dos quais 13 foram ainda excluídos, permanecendo 10 para análise qualitativa e 7 para a metanálise. Não foi observada diferença significativa no risco/ intensidade da dor após o tratamento endodôntico nesse estudo. O risco de dor foi de 1,09, com intervalo de confiança de 95%, variando de 0,87 a 1,38 (p=0,45). A diferença padronizada g de Hedges nas médias da intensidade da dor após 24 horas foi de ­ 0,05, com intervalo de confiança variando de ­ 0,21 a 0,11 (p=0,53). Conclusões: Nessa metanálise, não foram encontradas diferenças no risco e na intensidade da dor após o tratamento endodôntico com ProTaper e outros sistemas rotatórios ou reciprocantes (AU).

Introduction: The success of endodontic therapy depends not merely on their efficacy and proper completion but also on minimal patient discomfort. The purpose of this systematic review and meta-analysis is to evaluate the risk and intensity of post instrumentation endodontic pain in adult patients. Methods: A comprehensive search was performed in the MEDLINE via PubMed, Scopus, Web of Science, LILACS, BBO and Cochrane Library and SIGLE without restrictions. The annual conference of the IADR abstracts (1990-2016), and unpublished and ongoing trials registry were also searched. Dissertations and theses were searched using the ProQuest Dissertations and the Periodicos Capes Theses Databases. Only randomized clinical trials that compared the risk or intensity of pain resulting from endodontic treatment in adult patients were included. Results: After the removal of duplicates, 827 articles were identified. After title and abstract screening, 26 studies remained. Thirteen studies were further excluded while 10 studies remained for qualitative analyses and 7 for the meta-analysis. No significant difference in the risk/intensity of pain after endodontic treatment was observed in this study. The risk of pain ratio was 1.09, with a 95% confidence interval of 0.87 to 1.38 (p = 0.45). The Hedges g standardized difference in means of pain intensity at 24 h was -0.05, with a confidence interval varying from -0.21 to 0.11 (p = 0.53). Conclusions: No differences in risk and intensity of pain after endodontic treatment with ProTaper and other rotatory or reciprocating systems were found in this meta-analysis (AU).

Pre-emptive low-dose ketamine with local anesthesia reduces postoperative morbidity after third molar surgery: a systematic review and meta-analysis / Ketamina en dosis bajas con anestesia local reduce la morbilidad postoperatoria de la cirugía del tercer molar: revisión sistemática y metanálisis

Objective: This review addresses a clinical research question related to lower third molar surgery (L3MS): does the combination of pre-emptive low-dose ketamine with local anesthesia (KLA) reduce postoperative complications compared with local anesthesia (LA) alone? Material and methods: A systematic literature search was performed to identify eligible articles by electronic searches of PubMed, Cochrane Central Register of Controlled Trials, EBSCO Library, Web of Science and grey literature through June 2019 without data or language restrictions. We analyzed all randomized controlled clinical studies (RCTs) comparing use of KLA with use of LA in L3MS regarding pain, swelling, and trismus outcomes. The quality of evidence was rated according to Cochrane's tool for assessing risk of bias. Results: Five RCTs encompassing 230 extraction sites (KLA = 115, LA = 115) were included in this study. The standardized mean difference (SMD) with the 95% confidence interval (CI) was used to synthesize the results. The data show that there were significant differences between the two groups in post-operative pain (SMD -1.464, 95% CI -1.683 to -0.949, p= 0.001) and swelling (SMD -0.450, 95% CI -0.758 to -0.142, p= 0.004, all low quality evidence). However, there was no significant difference in the trismus (SMD -0.754, CI -1.487 to -0.022, p = 0.043, very low quality evidence). Conclusion: The combination of pre-emptive low-dose ketamine with LA significantly decreased pain and swelling within the first 24 hours after L3MS compared with the control group.

Objetivo: Esta revisión aborda una pregunta de investigación clínica relacionada con la cirugía del tercer molar inferior (L3MS): ¿la combinación de ketamina preventiva en dosis bajas con anestesia local (KLA) reduce las complicaciones postoperatorias en comparación con la anestesia local (AL) sola? Material y Métodos: Se realizó una búsqueda bibliográfica sistemática para identificar artículos elegibles mediante búsquedas electrónicas en PubMed, Registro Cochrane Central de Ensayos Controlados, Biblioteca EBSCO, Web of Science y literatura gris hasta junio de 2019 sin restricciones de datos ni de idioma. Se analizaron todos los estudios clínicos controlados aleatorios (ECA) que compararon el uso de KLA con el uso de LA en L3MS con respecto a los resultados de dolor, hinchazón y trismo. La calidad de la evidencia se clasificó de acuerdo con la herramienta Cochrane para evaluar el riesgo de sesgo. Resultados: Se incluyeron en este estudio cinco ECA que abarcan 230 sitios de extracción (KLA = 115, LA = 115). La diferencia de medias estandarizada (DME) con el intervalo de confianza (IC) del 95% se utilizó para sintetizar los resultados. Los datos muestran que hubo diferencias significativas entre los dos grupos en el dolor posoperatorio (DME -1,464; IC del 95%: -1,683 a -0,949; p= 0,001) e hinchazón (DME -0,450; IC del 95%: -0,758 a -0,142, p= 0,004, todas las pruebas de baja calidad). Sin embargo, no hubo diferencias significativas en el trismo (DME -0,754; IC: -1,487 a -0,022; p= 0,043, evidencia de muy baja calidad). Conclusión: La combinación de ketamina preventiva en dosis bajas con LA disminuyó significativamente el dolor y la hinchazón dentro de las primeras 24 horas después de la L3MS en comparación con el grupo de control.

Analgesia multimodal una alternativa para el paciente quirúrgico / Multimodal analgesia: an alternative for the surgical patient

Introducción: El dolor posterior a una intervención quirúrgica, es un síntoma frecuentemente observado, no cumple una función útil y el peligro de no tratarlo aumenta la morbilidad y mortalidad posoperatoria. Objetivo: Destacar la importancia de la analgesia multimodal en el control del dolor agudo posoperatorio. Métodos: Revisión en la literatura impresa tanto nacional como internacional, sobre la analgesia y la modalidad multimodal y además, se hizo búsqueda en Internet. En los artículos revisados se obtuvieron distintos aspectos clínicos de la analgesia multimodal y de sus protocolos. Resultados: En la actualidad para mitigar el dolor y alcanzar la máxima expresión en la analgesia posoperatoria se han desarrollado diferentes modalidades analgésicas, aunque de todas ellas solo ha alcanzado mayor grado de recomendación, la analgesia multimodal porque es capaz de conseguir con su efecto sinérgico y con pequeñas dosis, una mejor potencia para producir analgesia y menos efectos adversos. Consideraciones finales: La analgesia multimodal logra un control adecuado del dolor agudo posoperatorio, disminuye las complicaciones posoperatorias y la necesidad de analgesia de rescate, pero todo esto depende del protocolo de analgesia multimodal propuesto, la vía de administración de los fármacos elegidos, sus dosis y el cumplimiento de los intervalos de aplicación(AU)

Introduction: The pain after surgery is a frequently observed symptom, it is not a useful function and the danger of not treating it increases postoperative morbidity and mortality. Objective: To highlight the importance of multimodal analgesia in the control of acute postoperative pain. Methods: It was made a review in the printed literature both national and international on the multimodal analgesia, and in addition, a search in Internet. In the reviewed articles there were obtained different clinical aspects of multimodal analgesia and its protocolization. Results: Nowadays, in order to mitigate the pain and achieve the maximum expression in the postoperative analgesia, there have been developed different analgesic modalities, although of all of them it only has achieved a greater degree of recommendation, the multimodal analgesia because it is capable of achieving with its synergetic effect and with small doses, a better power to produce analgesia and fewer adverse effects. Conclusions: The multimodal analgesia achieved adequate control of acute postoperative pain, decreasing the inherent complications of this state and the need of rescue analgesia. All of the above depends on the proposed protocol of multimodal analgesia, the route of administration of the chosen drugs, their doses and the compliance of the application intervals(AU)

Age - Does it really count? A study of the Perioperative Morbidity and Long-Term Outcome in Patients Above 70 Years of Age Undergoing Spine surgery for Lumbar Degenerative Disorders / Idade - Deve ser levada em conta? Estudo da morbidade perioperatória e a evolução no longo prazo dos pacientes acima de 70 anos submetidos à cirurgia da coluna vertebral, devido a doenças degenerativas lombares

Abstract Objective To assess the long-term outcome and perioperative morbidity in spine surgeries for lumbar degenerative disorders and, thereby, to evaluate the safety of surgery in the aging population. Methods Retrospective study of patients aged > 70 years, operated for degenerative lumbar disorders between 2011 and 2015. We evaluated patient demographic, clinical and surgical data; comorbidities, perioperative complications, pre & postoperative pain scores and Oswestry disability index (ODI) scores, patient satisfaction and overall mortality. Results A total of 103 patients (Males: Females55:48) with mean age 74.6 years (70-85yrs) were studied. 60 patients (58.2%) had decompression alone, while 43 (41.8%) had decompression & fusion. Mean hospital stay was 5.7days. Mean follow-up was 47.6months (24-73mnths). Patients reported significant improvement in backpain (Numerical pain score 7.7 vs 1.6; p < 0.001), leg pain (Numerical pain score 7.4 vs 1.7; p < 0.001), disability (ODI 82.3 vs 19.1; p < 0.001) and walking distance (p < 0.001). 76% patients were satisfied with the results at the time of final follow-up. 26 patients (25.24%) had perioperative complications which were all minor, without mortality. Most common intraoperative & postoperative complications were dural tear (6.79%) & urinary tract infection (6.79%) respectively. Conclusions With meticulous perioperative care lumbar spine surgery is safe and effective in elderly population. Patients had longer mean hospital stay in view of the gradual and comprehensive rehabilitation program. Presence of comorbidities or minor perioperative complications did not increase the overall morbidity or affect the clinical outcomes of surgery in our study.

Resumo Objetivos Avaliar o resultado no longo prazo e a morbidade perioperatória em cirurgias da coluna vertebral, devido a doenças lombares degenerativas e, assim, avaliar a segurança da cirurgia na população idosa. Métodos Estudo retrospectivo de pacientes com idade superior a 70 anos, submetidos à cirurgia em virtude de distúrbios lombares degenerativos, entre 2011 e 2015. Foram avaliados os dados demográficos, clínicos e cirúrgicos dos pacientes; comorbidades; complicações perioperatórias; escores de dor no pré e no pós-operatório; índice de incapacidade de Oswestry (ODI, na sigla em inglês); satisfação do paciente e a mortalidade geral. Resultados Foram estudados 103 pacientes (homens:mulheres, 55:48) com idade média de 74,6 anos (70 a 85 anos). 60 pacientes (58,2%) apresentaram somente descompressão, enquanto 43 (41,8%) apresentaram descompressão e fusão. O tempo médio de internação foi de 5,7 dias. O tempo médio de acompanhamento foi de 47,6 meses (24-73 meses). Os pacientes relataram melhora significativa da dor nas costas (pontuação numérica da dor 7,7 versus 1,6; p < 0,001), dor nas pernas (pontuação numérica da dor 7,4 versus 1,7; p < 0,001), incapacidade (ODI 82,3 versus 19,1; p < 0,001) e distância percorrida a pé (p < 0,001). Um total de 76% dos pacientes estavam satisfeitos com os resultados no momento do acompanhamento final. 26 pacientes (25,24%) apresentaram complicações perioperatórias, todas sem relevância e sem mortalidade. As complicações intra e pós-operatórias mais comuns foram ruptura dural (6,79%) e infecção do trato urinário (6,79%), respectivamente. Conclusões Com meticulosos cuidados perioperatórios, a cirurgia da coluna lombar é segura e eficaz na população idosa. Os pacientes tiveram um maior tempo médio de internação hospitalar, em virtude do programa de reabilitação gradual e abrangente. A presença de comorbidades ou complicações perioperatórias sem relevância, não aumentou a morbidade geral, nem afetou os resultados clínicos da cirurgia em nosso estudo.

ABSTRACT Background Post-operative pain is the major consequence of Ksarasutra, Seton technique employed in Ayurvedic management of Low anal fistula. Surgeons are forced to prescribe Opioids and NSAIDs with pronounced untoward effects. Non pharmacological measures like Balneotherapy are used to improve circulation and relieve spasm in contemporary sciences. Aim To compare the efficacy of Khadira (Acacia catechu) and Sphatika (Potash alum) hot sitzbath with plain hot sitzbath in patients of low anal fistula treated with Ksarasutra. Method The study was single blind, double armed; prospective, randomized control clinical trial in which 30 patients were randomly allocated into two groups of 15 each on the basis of inclusion and exclusion criteria. Group A received hot sitzbath using Acacia catechu and alum infusion twice daily for 21 days. Group B received hot sitzbath using warm water for 21 days. The assessments were made on pain, post-surgical satisfaction burning sensation, tenderness, discharge, constipation, itching and incontinence. Result The disease was prevalent in the 4th decade of life, more in males (86.67%) involved in sedentary work (53.33%) residing in urban domicile, consuming mixed diet (100%). Both groups showed statistically significant improvement in outcome measures like pain, burning sensation, tenderness, discharge, constipation and itching. Conclusion On comparative analysis Acacia and Alum hot sitzbath was more effective in outcomes like pain, surgical satisfaction, burning sensation and discharge. There was no difference in the effect of both interventions with respect to outcome measures like constipation, itching and incontinence.

RESUMO Justificativa A dor pós-operatória é a principal consequência da técnica que utiliza seton de Ksarasutra no tratamento ayurvédico de fístula anal baixa. Os cirurgiões são impelidos a prescrever opiáceos e AINEs que possuem efeitos indesejáveis pronunciados. Medidas não farmacológicas como a balneoterapia são usadas nas ciências contemporâneas para melhorar a circulação e aliviar o espasmo. Objetivo Comparar a eficácia do banho quente de assento com Khadira (Acacia catechu) e Sphatika (Potash alum) com apenas banho de assento em pacientes com fístula anal baixa tratados com Ksarasutra. Método Estudo clínico prospectivo, cego e controlado de dois braços randomizados, no qual 30 pacientes foram alocados aleatoriamente em dois grupos de 15 pacientes cada com base nos critérios de inclusão e exclusão. O Grupo A recebeu banho de assento com Acacia catechu e infusão de alume duas vezes ao dia por 21 dias. O Grupo B recebeu banho de assento com água morna por 21 dias. Os desfechos avaliados foram dor, satisfação pós-cirúrgica, sensação de queimação, sensibilidade, corrimento, constipação, prurido e incontinência. Resultado A doença foi prevalente na 4ª década de vida, mais frequente no sexo masculino (86,67%), nos envolvidos em trabalho sedentário (53,33%), nos residentes em domicílios urbanos e nos que consumiam dieta mista (100%). Ambos os grupos apresentaram melhora estatisticamente significativa na avaliação dos resultados, tais como dor, sensação de queimação, sensibilidade, corrimento, constipação e prurido. Conclusão Na análise comparativa, o banho quente de assento com acácia e alume foi mais eficaz nos desfechos de dor, satisfação cirúrgica, sensação de queimação e corrimento. Não houve diferença em relação ao efeito de ambas as intervenções sobre os desfechos de constipação, prurido e incontinência.
