چکیده
Em um estudo recente conduzido por Stourac et al., discutiu-se se rocurônio e sugamadex beneficiam o tempo para intubação traqueal e outros desfechos do bloqueio neuromuscular (BNM) em comparação com succinilcolina, rocurônio e neostigmina em mulheres submetidas à anestesia geral para cesariana.1 A conclusão dos autores foi que rocurônio usado para indução de sequência rápida não é inferior em relação ao tempo necessário para a intubação. Além disso, houve ausência mais frequente de resistência durante a laringoscopia e menos mialgia em comparação com o uso de succinilcolina. Pois bem, nada de novo até aqui, mas ainda há a discussão se devemos usar succinilcolina ou rocurônio em paciente submetida à cesariana sob anestesia geral. Com base em cálculos, Benumof et al. previram que, em uma paciente adulta saudável de 70 kg, após apneia induzida por succinilcolina (1,0 mg.kg-1), a saturação de oxigênio (SatO2) começará a diminuir para menos de 90% após aproximadamente oito minutos. Porém, a fisiologia é alterada durante a gravidez em comparação com pacientes saudáveis.2 À medida que a gravidez progride, o consumo de oxigênio continua a aumentar e, em menor grau, o débito cardíaco também aumenta, o que resulta em menor conteúdo de oxigênio venoso misto e aumento da diferença de oxigênio arteriovenoso. Após a primeira metade da gestação, as gestantes em posição supina com frequência apresentam uma pressão parcial de oxigênio (PaO2) inferior a 100 mmHg (13,3 kPa).3 Isso ocorre porque a capacidade residual funcional (CRF) pode ser inferior à capacidade de
