BACKGROUND: Multiple factors may affect pancreatic enzyme levels even in the absence of pancreatitis. In the general intensive care unit (ICU), we examined the incidence, various clinical factors, and sequelae associated with elevated pancreatic enzymes in the neurosurgery ICU. METHODS: Eighty-nine patients who were admitted to the neurosurgery ICU with gastrointestinal symptoms and signs from January to October 2007 were classified into 2 groups according to their pancreatic enzymes as follows: normal pancreatic enzyme levels (n = 46) and elevated levels (n = 43). We analyzed the general data, including sex, age, indications for admission, types of surgery, initial Glasgow coma scale (GCS) score, neurosurgery ICU-stay days, and mechanical ventilator- use days. We also collected data on vital signs, serum markers, and drug prescriptions. Radiological examinations, including sonography and computed tomography (CT) scans of the abdomen were performed. RESULTS: Nearly half of the patients who were admitted to the neurosurgical ICU with gastrointestinal symptoms and signs had elevated serum pancreatic enzymes. Elevated pancreatic enzyme levels were significantly associated with anemia (p = 0.048) and renal failure (p = 0.026), and were not associated with sex, age, indications for admission, types of surgery, initial GCS, neurosurgery ICU-stay days, mechanical ventilator-use days, hypotension, fever, usual ICU drugs, and other serum hepatic markers. High pancreatic enzyme levels were associated with a high mortality (p = 0.02). Abdominal CT had a high positive-predictive rate for the diagnosis of pancreatitis (63%). CONCLUSION: Various neurosurgery events and diagnoses may lead to different degrees of serum pancreatic enzyme elevation. Patients with elevated pancreatic enzyme levels have a higher mortality rate than those with normal enzyme levels. We believe that abdominal CT should be indicated for patients if their amylase levels are more than 3-fold the upper normal limit and lipase levels are more than 5-fold.
