Severe pancreatitis is suggestive of a serious infection when there is an increase in body temperature, a decrease in blood pressure, and a decrease in white blood cell levels. In the early stage of the disease, patients with severe pancreatitis can develop aseptic inflammation because the pancreas can release some pancreatic enzymes, which can cause damage to normal tissues, and patients will show increased body temperature and leukocytosis. When the disease enters the infectious stage, peripancreatic abscess can appear, and in severe cases, abdominal abscess and infectious shock appear. Patients will show increased body temperature, and in severe cases, they will show cold limbs, weakened pulse, accompanied by a series of symptoms of infectious shock, such as decreased blood pressure, leukocyte content, etc. At this time, infection should be highly suspected. It is recommended that the patient go to the hepatobiliary surgery department of the local hospital in a timely manner to listen to the advice of a professional doctor, the above views are for reference only.
