Unnecessary investigations in patients with acute pancreatitis: arterial blood sampling and serum biochemistry.
Most patients admitted with acute pancreatitis undergo arterial blood gas sampling (ABG) to calculate the modified Glasgow score (MGS) and serum amylase and liver function tests (LFTs) are requested frequently during admission. This study aims to assess the necessity of these investigations. ⋯ We propose not performing ABGs if the MCS excluding the PaO2 component totals two or less. Clinical judgment would have to be exercised. Unnecessary serum biochemistry requests are frequent but at little financial expense.
