|
Forty five patients undergoing cesarean section were classified into 4 groups. In group 1, 11 patients received epidural anesthesia and were supine throughout the procedure. In group 2, 9 patients received epidural anesthesia and took left lateral tilt by the balloon under the right hip. In group 3, 11 patients received general anesthesia and took left lateral tilt by the same method. In group 4, 14 patients received general anesthesia and were supine. Maternal brachial and femoral systolic and diastolic pressures, cardiac output and heart rate, and newborns pH, pCO2, pO2 and bicarbonate concentration from the umbilical venous blood were measured. One minute and 5 minute Apgar score were also measured. The rate of decrease in the brachial arterial pressure was highest in Group 1. The rate of decrease in the femoral arterial pressure was also highest in Group 1 but statistically insignificant. The number of patients whose brachial and femoral arterial pressures decreased by more than 10% compared with pre-induction values was largest in Group I but statisticallly insignificant. There were no difference in cardiac outputs and heart rates among the groups. Newborns oxygen tesion from the umbilical venous blood was high in the groups received general anesthesia. But there were no difference in pH, pCO2, bicarbonate concentrations and 1 minute and 5 minute Apgar scores. |
