O uso da cirurgia laparoscópica atualmente é o padrão de terapia para muitos procedimentos abdominais e pélvicos em crianças de todas as idades. Oferece vantagens em comparação a procedimentos abertos em pacientes adultos e pediátricos, incluindo tempos de internação mais curtos, custos mais baixos, menos infecções e complicações (1.2). Os procedimentos aos quais a laparascopia pode ser aplicada incluem várias indicações abdominais, pélvicas e urológicas, como mostrado na Tabela 1. O manejo perioperatório dessas cirurgias apresenta desafios únicos ao anestesista, e os pacientes pediátricos em particular exigem considerações especiais quando comparados a adultos. Isso exige uma compreensão abrangente da fisiologia pediátrica e das nuances do procedimento cirúrgico. Após concluir este tutorial, o aprendiz entenderá o escopo de cirurgias laparoscópicas pediátricas, as alterações fisiológicas associadas e o manejo anestésico de tais casos.
