ABSTRACT
Abstract Background: Postoperative Nausea and Vomiting (PONV) is a common complication of general anesthesia. Several kinds of antiemetics, including 5-Hydroxytryptamine3 (5-HT3) receptor antagonists, and Neurokinin-1 (NK-1) receptor antagonists have been used to treat PONV. Objectives: To compare the antiemetic effect of NK-1 receptor antagonists, including fosaprepitant. Data sources: Online databases (PubMed, MEDLINE, Scopus, The Cochrane Library databases) were used. Study eligibility criteria, participants, and interventions: Randomized Controlled Trials (RCTs) performed in patients over 18 years with ASA-PS of I‒III, aimed to assess the efficacy of antiemetics including NK-1 receptor antagonists and 5-HT3 receptor antagonists, and compared the incidence of PONV were included. Study appraisal and synthesis methods: All statistical assessments were conducted by a random effect approach, and odds ratios and 95% Confidence Intervals were calculated. Results: Aprepitant 40 mg and 80 mg significantly reduced the incidence of vomiting 0‒24 hours postoperatively (Odds Ratio [OR = 0.40]; 95% Confidence Interval [95% CI 0.30‒0.54]; p < 0.001, and OR = 0.32; 95% CI 0.19‒0.56; p < 0.001). Fosaprepitant could also reduce the incidence of vomiting significantly both 0‒24 and 0‒48 hours postoperatively (OR = 0.07; 95% CI 0.02‒0.24; p < 0.001 and OR = 0.07; 95% CI 0.02‒0.23; p < 0.001). Limitations: Risk factors for PONV are not considered, RCTs using multiple antiemetics are included, RCTs for fosaprepitant is small, and some bias may be present. Conclusions and implications of key findings: Aprepitant and fosaprepitant can be effective prophylactic antiemetics for postoperative vomiting. However, more studies are required for higher-quality meta-analyses. Systematic review registration number: CRD42019120188.
Resumo Histórico: Náusea e Vômito no Pós-Operatório (NVPO) é um evento adverso frequente da anestesia geral. Várias classes de antieméticos, incluindo antagonistas do receptor 5-Hidroxitriptamina3 (5-HT3) e antagonistas do receptor da Neurocinina-1 (NK-1), têm sido utilizados para tratar a NVPO. Objetivo: Comparar o efeito antiemético dos antagonistas do receptor NK-1, incluindo o fosaprepitanto. Fontes de dados: Foram utilizadas bases de dados on-line (PubMed, MEDLINE, Scopus, The Cochrane Library). Critérios de elegibilidade do estudo, participantes e intervenções: Foram incluídos Estudos Clínicos Randomizados (ECR) realizados em pacientes acima de 18 anos classificação ASA I a III, com o objetivo de avaliar a eficácia de antieméticos que incluíssem antagonistas do receptor NK-1 e antagonistas do receptor 5-HT3, e que comparassem a incidência de NVPO. Métodos de avaliação e síntese do estudo: Todas as avaliações estatísticas foram realizadas por abordagem de efeito aleatório e foram calculadas razões de chances e Intervalos de Confiança de 95%. Resultados: As doses de 40 mg e 80 mg de aprepitanto reduziram significantemente a incidência de vômito no período de 0 a 24 horas pós-operatórias (razão de chances [OR = 0,40]; Intervalo de Confiança de 95% [95% IC] 0,30-0,54; p < 0,001 e OR = 0,32; 95% IC 0,19-0,56; p < 0,001). O fosaprepitanto pode também reduzir significantemente a incidência de vômito tanto de 0-24 horas como no período de 0-48 horas pós-operatórias (OR = 0,07; 95% IC 0,02-0,24; p < 0,001 e OR = 0,07; 95% IC 0,02-0,23; p < 0,001). Limitações: Os fatores de risco para NVPO não foram analisados, ECRs usando múltiplos antieméticos foram incluídos, ECRs para fosaprepitanto tinham amostras pequenas, podendo haver algum viés. Conclusões e implicações dos principais achados: Aprepitanto e fosaprepitanto podem ser drogas antieméticas profiláticas efetivas para vômito no pós-operatório. No entanto, são necessários mais estudos para elaboração de meta-análises de melhor qualidade. Número de registro da revisão sistemática: CRD42019120188.
