To determine the clinical indicators of the severity of pancreatitis, the following aspects should be judged: 1. Through clinical symptoms, pancreatitis if severe patients will show signs of shock such as irritability, shallow coma, cold skin sweat or progressive drop in blood pressure. 2. Through physical signs, severe pancreatitis will show signs of peritonitis, including pressure pain and rebound pain throughout the abdomen, and even positive mobile turbid sounds. 3. Laboratory tests can be performed. The significant increase in blood and urine amylase as well as the significant decrease in blood calcium, with blood calcium values below 1.8 mmol/L, proves that the severity of pancreatitis is very high. 4. You can further check the amylase level of the peritoneal fluid through laparotomy fluid, which also helps to determine the severity of the pancreas.
