Randomized Controlled Trial Clinical Trial
Awareness following different techniques of general anaesthesia for caesarean section.
Using the isolated arm technique, the frequency of awareness was evaluated in 50 full-term patients undergoing elective Caesarean section under general anaesthesia. In 20 patients, anaesthesia was induced with thiopentone 4 mg kg-1, and in the other 30 patients, induction was with ketamine 1.5 mg kg-1. ⋯ Awareness was significantly greater after induction with thiopentone (14/20) than after ketamine (4/30). There were no significant differences in Apgar scores or umbilical vein blood-gas values in the newborns.

Randomized Controlled Trial Clinical Trial
Neurobehavioural effects of propofol on the neonate following elective caesarean section.
Forty mothers undergoing elective Caesarean section under general anaesthesia were allocated randomly to receive either propofol 2.8 mg kg-1 (n = 20) or thiopentone 5 mg kg-1 (n = 20) for induction of anaesthesia. Twenty neonates delivered by uncomplicated vaginal delivery were evaluated also as unmedicated controls. Neurobehavioural examinations were carried out at 1, 4 and 24 h after delivery. ⋯ Newborn children examined 1 h after birth, after maternal anaesthesia with propofol, showed a depression in alert state, pinprick and placing reflexes, and mean decremental count in Moro and light. There was a generalized irritability in 25% of them. This depression was not observed at 4 h.
