The Ranson criteria form a clinical prediction rule for predicting the severity of acute pancreatitis. They were introduced in 1974. ==Usage== For non-gallstone pancreatitis, the parameters are: At admission: # Age in years > 55 years # White blood cell count > 16000 cells/mm3 # Blood glucose > 11 mmol/L (> 200 mg/dL) # Serum AST > 250 IU/L # Serum LDH > 350 IU/L Within 48 hours: # Serum calcium < 2.0 mmol/L (< 8.0 mg/dL) # Hematocrit fall > 10% # Oxygen (hypoxemia PaO2 < 60 mmHg) # BUN increased by 1.8 or more mmol/L (5 or more mg/dL) after IV fluid hydration # Base deficit (negative base excess) > 4 mEq/L # Sequestration of fluids > 6 L The criterion for point assignment is that a certain breakpoint be met at anytime during that 48 hour period, so that in some situations it can be calculated shortly after admission. It is applicable to non-gallstone pancreatitis. The mnemonic GALAW AND CHOBBS can be used to remember this criteria. For gallstone pancreatitis, the parameters are:〔http://bestpractice.bmj.com/best-practice/monograph/66/diagnosis/criteria.html〕 At admission: # Age in years > 70 years # White blood cell count > 18000 cells/mm3 # Blood glucose > 12.2 mmol/L (> 220 mg/dL) # Serum AST > 250 IU/L # Serum LDH > 400 IU/L Within 48 hours: # Serum calcium < 2.0 mmol/L (< 8.0 mg/dL) # Hematocrit fall > 10% # Oxygen (hypoxemia PaO2 < 60 mmHg) # BUN increased by 0.7 or more mmol/L (2 or more mg/dL) after IV fluid hydration # Base deficit (negative base excess) > 5 mEq/L # Sequestration of fluids > 4 L 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ranson criteria」の詳細全文を読む スポンサード リンク
