Abstract

BACKGROUND
It is well known that cardiac output increases the greatest after a normal vaginal delivery. This study was to demonstrate the change of cardiac output after delivery by a cesarean section.
METHODS
Eighty three women who underwent an elective cesarean section were involved in this study. They were anesthetized with enflurane, O2 and N2O (1:1) after injection of glycopyrrolate IM as a premedicant. Hemodynamic variables (CO, CI, SVR, SVRI, SI, EF, MAP and HR) were measured at three different time points; preoperation, 10 and 30 minutes after delivery by using a thoracic bioimpedence.
RESULTS
The values of CO, CI, SI, and EF at 10 and 30 minutes after delivery were increased significantly (P< 0.05) compared to those of preoperation. The CO of 10 and 30 min after delivery increased 35.4% and 30.7% retrospectively. However, the values of SVR and SVRI were decreased significantly (P< 0.05) and the values of MAP and HR were not changed at 10 and 30 minutes after delivery when compared to those of preoperation.
CONCLUSIONS
From these result, the CO after delivery during a cesarean section under enflurane anesthesia increased significantly. Therefore, decompensation in the early postpartum period is a risk in patients with compromised cardiac status.
