The lying position after appendicitis surgery is determined by the patient’s anesthesia and the type of surgery. For patients under general anesthesia, the postoperative position should be semi-recumbent with the head to the side, which helps prevent the patient from the risk of nausea, vomiting, choking and asphyxiation caused by the reaction to anesthesia. For patients who have taken epidural or lumbar anesthesia, the postoperative period should be taken in a flat position for 6-8 hours, which effectively enables the patient’s anesthesia level to always be controlled below the navel so as to avoid respiratory difficulties caused by too high a level. If patients do not have enough time postoperatively, it may also cause extravasation of cerebrospinal fluid and low cranial pressure, resulting in complications such as postoperative headache. The decision on the postoperative lying position for appendicitis must be based on a combination of the patient’s condition and the type of anesthesia.
