Improper ventilation greatly increases the probability of gas entering the stomach and causing gastric insufflation, thus making the induction period of anesthesia the stage most prone to bloating during the whole perioperative period. Severe gastric insufflation not only increases the risk of reflux aspiration during anesthesia, but also adversely affects the operation and postoperative recovery. In this regard, many scholars at home and abroad have done relevant research, by using different ventilation methods or applying special intervention measures, or even avoiding positive pressure ventilation to reduce the occurrence of gastric insufflation.
