Whether it is normal for patients to have fever after cholecystectomy is based on the time, temperature and whether the patient has abdominal symptoms, etc.: First, if the patient has hypothermia within 24-48 hours after surgery, the body temperature does not exceed 38.5℃, and the patient’s body temperature can gradually return to normal by giving physical cooling, and the patient has no clinical symptoms such as abdominal pain and bloating. At this time, more consider the absorption of heat after surgery, which is a normal physiological phenomenon. Second, if the patient after 72 hours of surgery appeared sudden chills, high fever, body temperature more than 38.5 ℃, give physical cooling patient body temperature can not return to normal, the patient accompanied by obvious abdominal pain, abdominal distension and other clinical symptoms. This situation is highly suspicious that the patient is accompanied by complications such as abdominal infection, biliary fistula and bleeding, which is abnormal.
