After gastric perforation surgery, the patient will be unconscious for a period of time related to the anesthesia, usually about half an hour. The main symptoms of gastric perforation include abdominal pain, vomiting, and shock, which can be secondary to gastric ulcers or stomach cancer. Patients with gastric perforation should receive prompt medical treatment to avoid life-threatening injuries. The main treatment for gastric perforation is surgery, in which general anesthesia is used. The patient will fall asleep during the general anesthesia and the anesthetic will gradually wear off after the surgery. The patient wakes up about half an hour after the surgery. If the patient is fully awake, the time required varies according to the individual circumstances of each person, and it takes about two hours to fully wake up.
