In order to prevent vomiting during general anesthesia and abdominal distension after operation, the time of fasting and drinking water before operation is
In order to prevent vomiting during general anesthesia and abdominal distension after operation, the preoperative fasting and drinking time is 8 hours and 4 hours before operation.

The main purpose of fasting before operation is to reduce the risk of nausea and vomiting during operation, because general anesthetics inhibit swallowing and cough reflex. If the patient does not fast, when vomiting occurs during operation, these reflexes will be lost, and vomit may enter the airway, leading to aspiration pneumonia. This measure is also helpful to reduce the occurrence of postoperative abdominal distension.
