Thirty-two patients received lumbar extradural anaesthesia for elective Caesarean section. The results obtained from this series were compared with those from a similar (control) group of parturients who received general anaesthesia. The extradural group (mothers and infants) were metabolically acidaemic relative to control. However, maternal to fetal blood-gas differences were comparable in the two series. Infants sustained respiration more rapidly after regional blockade, otherwise the clinical condition of the infants was similar with extradural and general anaesthesia. No advantage of conduction over general anaesthesia was evident from this study, with respect to the biochemical status of the infant at birth.
32例患者接受了择期剖宫产的腰段硬膜外麻醉。将该组患者的结果与接受全身麻醉的类似（对照）产妇组的结果进行比较。硬膜外组（母亲和婴儿）相对于对照组在代谢上存在酸血症。然而，两组中母亲与胎儿的血气差异相当。区域阻滞（硬膜外麻醉）后婴儿恢复呼吸更快，除此之外，硬膜外麻醉和全身麻醉下婴儿的临床状况相似。就出生时婴儿的生化状态而言，本研究未显示出硬膜外麻醉相较于全身麻醉的优势。
