Fetal-neonatal status following caesarean section for fetal distress.
Fetal biochemical and neonatal clinical data were compiled in 126 emergency Caesarean sections performed for fetal distress. The choice of anaesthetic technique was determined by the wishes of the mother. General anaesthesia was administered to 71 parturients and regional analgesia to 55 (subarachnoid block 33, extension of extradural block 22). The aetiologies of fetal distress and the skin incision-delivery and uterine incision-delivery intervals were not significantly different between the two anaesthesia groups. Umbilical artery blood pH values were higher than the last scalp capillary blood pH values in 63% of the general anaesthesia and in 80% of the regional analgesia cases. Umbilical vein and artery blood-gas and pH data were similar in the two anaesthesia groups, but 1-min Apgar scores were significantly better following regional analgesia. Despite the presence of fetal distress, subarachnoid blockade was a most suitable method of anaesthesia in experienced hands.
