Sevoflurane and propofol are the most popular drug choices for maintenance of general anaesthesia for caesarean section. However, effects of these two anesthetics on maternal and fetal outcomes after caesarean section haven't been compared directly. The aim of this study is to compare the effects of sevoflurane and propofol as maintenance of general anesthesia, and to try to determine which anesthetic is better for maternal and fetal outcomes after caesarean section.
