The participants included 123 women, 30 in experimental group 1 (post anesthesia 30 min), 22 in the experimental group 2 (post anesthesia 4 hours), 23 in experimental group 3 (Post anesthesia 24 hours), and 48 in a control group. Data were collected using a structured questionnaire consisting of general characteristics, self reported time when gas was first passed. Differences in the time when first gas was passed among four groups were analyzed using ANOVA.
