The comparison of different anaesthetic methods for abdominal surgery in infants

Objective To explore the anaesthetic method which is safe,effective and practical for the abdominal surgery in infants.Methods Sixty infants(aged from 3 days to 3 years) undergoing abdominal surgery were randomly divided into two groups.The groupⅠreceived caudal block anesthesia and light general anesthesia,and the groupⅡ received intravenous anesthesia with endotracheal intubation or laryngeal mask.HR and SBP in different time points,i.e.before anesthesia,during and immediately after the operation were observed.The average doses of propofol and ketamine used,recovery time and quality were compared between two groups.Results Obviously increased HR was observed during operation in groupⅡ when compared with groupⅠ(P0.01);although HR was increased during the operation in both groups,comparison within groups showed the increase was more obvious in groupⅡ(P0.01) than that in groupⅠ(P0.05),BP did not change during operation in groupⅠ,but it increased significantly in groupⅡ(P0.01).In comparison with groupⅠ The doses of propofol and ketamine administered in groupⅡ were more,and the recovery time was longer(P0.01).Conclusion Caudal block anesthesia combined with light general anesthesia is ideal and practical anesthetic method for abdominal surgery in infants.
