Postoperative intestinal obstruction may be related to intestinal adhesion, late awakening from postoperative anesthesia, abdominal inflammation and so on. 1. Intestinal adhesion: the plasma membrane on the surface of the patient’s intestine may be damaged in the process of surgical operation, and the postoperative wound may form adhesion between the plasma membrane and the plasma membrane in the process of normal healing, thus causing intestinal obstruction. 2. Late awakening of postoperative anesthesia: if the anesthesia is not fully awakened within 24-72 hours after the abdominal surgery, that is, if the anesthesia is awakened too late after the surgery, the patient may suffer from different degrees of intestinal paralysis, and the recovery of intestinal peristalsis is not good, which will easily cause the patient’s abdominal cavity to be infected, and then lead to paralytic intestinal obstruction. 3. Inflammation of the abdominal cavity: inflammatory reaction may occur in the peritoneum after surgery, resulting in a large amount of fibrin-containing fluid exudation and edema of the intestinal wall, which leads to early postoperative inflammatory intestinal obstruction. After the appearance of postoperative intestinal obstruction, you should promptly inform your doctor of the uncomfortable symptoms, and be treated by a professional doctor.
