Abstract：
:This study was designed to re-evaluate neonatal condition at birth following elective cesarean section performed with epidural anesthesia and a modified technique of general anesthesia. Two groups of 20 patients were studied. Twenty received epidural anesthesia with 2 per cent lidocaine-carbon dioxide-epinephrine, and 20 patients were given general anesthesia. Modifications of our previous general anesthetic technique included the administration, to the mother, of high inspired concentrations of oxygen (66 per cent) prior to delivery, short induction-to-delivery intervals, and positioning of the mother in a 20 degrees left lateral tilt position. No significant differences in oxygen tension and acid-base balance in umbilical venous and arterial blood were demonstrated between the two sets of neonates. One-and five-minute Apgar scores and time to sustained respiration were similar in both groups. Our observations of the infants immediately after delivery led us to conclude that either anesthesia technique is acceptable for elective cesarean section.
