CONTEXTO E OBJETIVO: Como as taxas de partos cesáreos aumentaram, o tipo de anestesia na cesariana ganhou importância. Comparamos os efeitos da anestesia geral e da raquianestesia sobre os resultados maternos e fetais em casos de gestação única e no termo, com cesariana eletiva. TIPO DE ESTUDO E LOCAL: Ensaio clínico prospectivo, randomizado e controlado, em hospital público terciário. MÉTODOS: Estudo realizado com 100 pacientes que se submeteram a cesariana por indicação eletiva. As pacientes foram divididos aleatoriamente em grupos recebendo anestesia geral (n = 50) e raquianestesia (n = 50). Resultados maternos hematológicos pré e pós-operatórios, variáveis hemodinâmicas intra e pós-operatórias e resultados perinatais foram comparados entre os grupos. RESULTADOS: As médias de ruídos intestinais (P = 0,036) e tempo de descarga de gás (P = 0,049) foram significativamente mais elevadas e os valores de diferença de hemoglobina na 24a hora (P = 0,001) foram maiores no grupo anestesia geral. Os valores médios de hematócrito e hemoglobina na 24a hora (P = 0,004 e P < 0,001, respectivamente), o volume de urina na primeira hora de pós-operatório (P < 0,001) e a pontuação mediana de Apgar no primeiro minuto (P < 0,0005) foram significativamente maiores, e o tempo até o primeiro requerimento de analgésicos também foi significativamente maior (P = 0,042) no grupo raquianestesia. CONCLUSÃO: Nos casos eletivos, raquianestesia é superior à anestesia geral em termos de conforto pós-operatório. Em gestações com risco de sofrimento fetal, seria adequado preferir raquianestesia, levando em conta o Apgar no primeiro minuto. REGISTRO DE ENSAIO CLÍNICO: NTR17990
