Anaesthetic technique for elective caesarean section and neurobehavioural status of newborns

Ninety healthy parturients undergoing elective caesarean section were randomly allocated to receive either general (n = 30), epidural (n = 30) or spinal (n = 30) anaesthesia. Acid-base status, Apgar score and neurobehavioural status, using the neurologic and adaptive capacity scoring (NACS) system, were studied in the newborn. Apgar scores and acid-base parameters were similar in all the three groups. NACS testing revealed significantly more vigorous babies in the spinal anaesthesia group than in the other two groups at 15 min and 2 h interval after delivery, despite a higher incidence of maternal hypotension. We conclude that newborns tend to have a better neurobehavioural status in the early post-delivery period if their mothers receive spinal anaesthesia rather than general or epidural anaesthesia for caesarean section.
