*
Values calculated from those patients who had laboratory values measured; not every patient had all laboratory tests.
†
Comparison of survivors versus nonsurvivors.
‡
To convert glucose from mg/dL to mmol/L, multiply by 0.0555; to convert creatinine to µmol/L, multiply by 88.3; to convert BUN to mmol/L, multiply by 0.357.
tCO2 indicates total serum CO2 concentration; WBC, white blood cell count; PCO2, partial pressure of carbon dioxide; BUN, blood urea nitrogen.
