Objective: To observe the respiratory and hemodynamic changes in children undergone laparoscopic operation. Methods: Three groups of children, ASAⅠ~Ⅱ, were involved in this study. In Group I, 30 cases of neonate with megacolon were anesthetized with general anesthesia, controlled ventilation and combined with epidural block. In Group II, 20 children aged 4-12, were undergone varicosity exploration under spontaneous breathing general anesthesia combined with epidural block. 6 cases in Group III (aged 4-12) were undergone lower abdominal laparoscopic operations under basal anesthesia with epidural block. In all the cases, HR, BP, pH, PetCO2 and PaCO2 were measured before induction, 10 minutes after epidural block and 10, 20, 40 minutes after abdominal carbon dioxide insufflation. Results: There are both respiratory and hemodynamic changes in all groups after abdominal carbon dioxide insufflation with PetCO2 and PaCO2 increasing. In group I, the airway peak pressure (PP) was increased obviously but the hemodynamic changes remained normal. The respiratory and circulatory changes in group III was normal, but in group II the PetCO2, PaCO2 and pH changed obviously. Conclusion: Laparoscopic operation could cause temporary respiratory and hemodynamic disorders in children. Controlled ventilation in general anesthesia can lighten or eliminate the hyper-carbon dioxide caused by spontaneous breathing. Basal anesthesia with epidural block can be used in elder children or in short term laparoscopic operation.
