Effect of obstructive jaundice on recovery from sevoflurane anesthesia in pediatric patients / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the effect of obstructive jaundice on recovery from sevoflurane anesthesia in pediatric patients. Methods A total of 80 pediatric patients scheduled for elective surgery were included, 42 pediatric patients with biliary atresia scheduled for Kasai operation served as obstructive jaundice group ( group OJ ) , and 38 pediatric patients scheduled for other operations served as control group ( group C) . Pediatric patients were 1-4 months old and full?term infants, and weighed 3.2-8.0 kg. Anesthesia was maintained with inhalation of 2%-4% sevoflurane during surgery, and pediatric patients inhaled 4% sevoflurane staring from peritoneum closure until the end of surgery. The duration from closing sevoflurane vaporizer to BIS value reaching 60, 70, 80 and 90 was recorded. The duration from stop of sevoflurane inhalation to BIS value returning to 60, 70, 80 and 90 was recorded. The duration from termination of sevoflurane inhalation to the time for tidal volume returning to 6 ml∕kg, to the time for muscle strength recovering to grade Ⅲ, to spontaneous eye opening and to tracheal extubation, and the corresponding BIS values were recorded. BIS value while entering the operating room, BIS value at the end of surgery, and the highest BIS value during recovery from anesthesia were recorded. The occurrence of delayed emergence from anesthesia was recorded. Results Compared with group C, the duration from termination of sevoflurane inhalation to spontaneous eye opening and to tracheal extubation were significantly prolonged, and BIS value at the end of surgery was decreased, and no significant change was found in the other parameters in group OJ. No pediatric patients developed delayed emergence from anesthesia in the two groups. Conclusion When only sevoflurane is used for inhalation anesthesia, although the time for recovery from anesthesia is prolonged, it shows no significant difference clinically in pediatric patients with obstructive jaundice.
