A comparison of spinal and general anaesthesia for elective caesarean section: effect on neonatal condition at birth.
The condition of 74 neonates delivered by elective caesarean section under general anaesthesia was compared with that of 63 neonates delivered under spinal anaesthesia. When the uterine incision - delivery interval was less than 3 min, neonates in the spinal group exhibited a higher Apgar score at 1 min (P < 0.002) and a higher mean umbilical venous pH (P < 0.05) than the equivalent general anaesthesia group; a significantly greater proportion of the neonates delivered under general anaesthesia had an umbilical venous pH<7.28 at delivery (P < 0.05), a fact which previous work suggests is important. Among anaesthetized mothers inspired oxygen concentration (33% or 50%) before delivery had no significant effect upon neonatal outcome. It is concluded that neonates delivered at elective Caesarean section under spinal anaesthesia are in better condition than those delivered under general anaesthesia.

A case of hyperemesis gravidarum treated with artificial nutritional support.
A case of severe hyperemesis gravidarum is described in which the parturient required nutritional support. Initially a trial of enteral feeding was attempted but was unsuccessful. Subsequent parenteral nutrition allowed the remainder of the pregnancy to continue and a live infant was delivered by caesarean section at 34 weeks gestation. Criteria for using artificial feeding, the nutritional requirements of a pregnant woman and the potential hazards to the pregnancy by giving artificial nutritional support are reviewed.

A survey of coagulation screening practices in preeclampsia and low-dose aspirin prophylaxis.
In a postal survey of 47 hospitals, consultant anaesthetists were asked their policies for investigating coagulation in parturients with preeclampsia and for those taking aspirin prophylaxis. There was some agreement over policies for mild to moderate preeclampsia. The study also showed that significant numbers of the smaller units encountered aspirin treatment but that there was little consensus on how to respond to it.
