Abstract: 【Abstract】 Objective To investigate the epidemiological characteristics and clinical significance of serum amylase in postoperative patients with ICU. Methods A retrospective analysis of 395 cases of eligible postoperative patients in ICU, we observed underlying disease, operative site, blood and urine amylase, blood lipase and imaging changes, and compared the change of blood amylase in patients with increased amylase. Results serum amylase was elevated in 43.3% postoperative patients in ICU, began by 1-3 days, peaked by 2-3 days, increased 1-2 times, kept 1-3 days. The percentage was respectively 5.3%, 7.6%, 1.8% and 1.8% with urine amylase, lipase, imaging changes and diagnosis of pancreatitis. The incidence rate was significantly lower in patients with elevated serum amylase with diabetes mellitus (P< 0.05), and was high in upper abdomen, head and neck surgery (P<0.05). Conclusion The serum amylase was elevated during 3 days in 43.3% postoperative patients in ICU. The incidence rate was the highest in upper abdominal, head and neck surgery. The incidence rate was reduced in the patient with diabetes mellitus. But the urine amylase and lipase rarely increased, the patient was very few with diagnosis of acute pancreatitis.
