To explore the effects of oral administration of simethicone of parturients after cesarean section on the recovery of their gastrointestinal function. Methods: A total of 150 parturients who had undergone cesarean section in hospital were selected and were randomly divided into study and control groups (75 cases in each group) between January 2022 and December 2023. The parturients in both groups were treated with postoperative routine treatment, while the parturients in the study group were given oral administration of simethicone emulsion after surgery until their defecation stopped additionally. The postoperative recovery of gastrointestinal function, the lactation situation, the complications rate, and the maternal satisfaction of the parturients were observed and compared between the two groups. Results: The first defecation time (62.53±5.72 d), the anal exhaust time (27.46±3.82 d), the bowel sounds recovery time (19.58±2.93 d) and the first lactation time (30.52±6.91 h) of the parturients in the study group after cesarean section were significantly earlier than those (69.84±6.36 d, 33.01±4.45 d, 21.39±3.17d and 34.39±7.24 h) of the parturients in the control group. The total rate (5.3%) of the complications, such as abdominal pain, abdominal distension and nausea/vomiting, of the parturients in the study group after cesarean section was significantly lower than that (17.3%) of the parturients in the control group. The satisfaction (89.3%) of the parturients in the study group after cesarean section was significantly higher than that (74.7%) of the parturients in the control group, and the postoperative hospital stay (4.62±0.87 d) of the parturients in the study group was significantly shorter than that (5.38±1.14 d) of the parturients in the control group (all P<0.05). Conclusion: The oral administration of simethicone emulsion of the parturients after cesarean section can promote their recovery of postoperative gastrointestinal function, shorten their lactation and hospitalization time, and reduce the risk of their postoperative complications, such as bloating and abdominal pain, and which can improve the postoperative satisfaction for the clinical service of the parturients.
