Resumo

JUSTIFICATIVA E OBJETIVOS: A analgesia no pós-operatório é desejada pelos pacientes e tem sido praticada pela maioria dos anestesiologistas. Além dos opióides, os anestésicos locais têm sido utilizados nos bloqueios periféricos e centrais para se obter a analgesia pós-operatória. O objetivo deste estudo foi comparar duas técnicas de bloqueio dos nervos intercostais para analgesia pós-operatória em colecistectomias abertas. MÉTODO: Sessenta pacientes foram submetidos a colecistectomias abertas com incisão subcostal e receberam bloqueio intercostal (Grupo IC, n=30) ou bloqueio interpleural (Grupo IP, n=30), ambos com 100 mg de bupivacaína a 0,5% com adrenalina, para analgesia pós-operatória. Foram avaliados os tempos de analgesia e as queixas relatadas pelos pacientes. RESULTADOS: A qualidade da analgesia foi considerada boa para ambas as técnicas. A duração média de analgesia foi de 505 minutos no grupo IP e 620 minutos no grupo IC, não havendo diferença estatística entre eles. Náuseas, vômitos e dor abdominal leve foram as queixas pós-operatórias mais freqüentes. Não se constatou qualquer complicação pós-operatória associada exclusivamente aos bloqueios, assim como não foi evidenciado nenhum caso de pneumotórax. CONCLUSÕES: Concluiu-se que as técnicas promoveram analgesia satisfatória após colecistectomia, sendo que o bloqueio interpleural apresentou maior facilidade de execução.

Abstract

BACKGROUND AND OBJECTIVES: Postoperative analgesia is a wish of all surgical patients and has been used by most anesthesiologists. In addition to opioids, local anesthetic agents have been employed for peripheral and central blocks. The purpose of this study was to evaluate and to compare intercostal and interpleural blocks for post-cholecystectomy analgesia. METHODS: Sixty patients undergoing open cholecystectomy with subcostal incision, received either intercostal block (Group IC, n = 30) or interpleural block (Group IP, n = 30), for postoperative analgesia, both with 0.5% bupivacaine (100 mg) with epinephrine. Analgesia duration and patients’ complaints were evaluated. RESULTS: Analgesia was considered satisfactory for both groups. Mean analgesia duration was 505 minutes for Group IP and 620 minutes for Group IC, with no statistical significant difference. Nausea, vomiting and mild abdominal pain were the most frequent postoperative complaints. There was no postoperative complication related to blockade and no pneumothorax was detected. CONCLUSIONS: We concluded that both techniques were effective in promoting post-cholecystectomy analgesia, but interpleural block was easier to perform.
