The effects of oral fluid intake an hour before cesarean section on regurgitation incidence.

Background: The fear of aspiration of gastric contents and its life-threatening disadvantages in patients have encouraged many medical practitioners to follow conservative policies for clear fluid/liquid and solid intake from midnight to the time of surgery. These policies have been pursued more severely in case of pregnant women, leading the physicians to follow "nil per os" policy. The aim of this study was to determine and compare the incidence of regurgitation in two groups of pregnant women during general anesthesia for cesarean section, with standard fasting policy and taking clear fluid an hour prior to the induction of anesthesia.
