| Abstract |
BACKGROUND
It is already known that systemic vascular resistance (SVR) is decreased during pregnancy. In addition, one of the large hemodynamic changes when using propofol is also a decrease in SVR, more profoundly than is found with enflurane. It might therefore be suggested that hemodynamic changes are more prominent in cesarean section during propofol anesthesia, compared with enflurane anesthesia. This study was designed to investigate these possible changes by propofol anesthesia.
METHODS
One hundred thirty six women for elective cesarean section were involved in this study. They were divided into 2 groups: group E (n = 74), anesthesia with thiopental, enflurane, and N2O, and group P (n = 62), anesthesia with propofol and N2O. All patient were given glycopyrrolate as premedicants. The hemodynamic variables (MAP, HR, CO, CI, SVR, SVRI, SI, and EF) were measured by bioimpedence at the five different time points: at preoperation, after induction, after intubation, during push abdomen, and after delivery.
RESULTS
The variables of hemodynamics did not change significantly when both groups were compared, except that MAP, SVR and SVRI at after induction and HR during push and after delivery in group P were lower compared with respective variables in group E.
CONCLUSION
From these results, we concluded that there were no significant changes in cardiovascular system (CVS) by propofol anesthesia, compared with enflurane anesthesia in cesarean section patients. It is therefore suggested that propofol anesthesia is safe in considering hemodynamics for cesarean section. |
