OBJECTIVE: This study was done to evaluate the differences in @entity51 ( @entity51 ) clearance, pH normalization, and the occurrence of complications between survivors and nonsurvivors after trauma. DESIGN: Concurrent data entry with retrospective review. METHODS: @entity130 @entity1 meeting registry criteria from July 1990 through August 1995 with arterial blood gases performed within 1 hour of admission and admission @entity51 < or = -6 were included. Data was grouped by @entity51 category (moderate, -6 to -9; severe, < or = -10). Group means +/- SEM were compared with a two-tailed t test. MEASUREMENTS AND MAIN RESULTS: Six hundred seventy-four @entity1 met entry criteria. Survivors in both the moderate and severe @entity51 groups had improved their @entity51 within 4 hours and normalized their @entity51 by 16 hours. Nonsurvivors did not improve their @entity51 category until 8 hours (for the severe group) and 16 hours (for the moderate group) and did not normalize @entity51 before 24 hours. The @entity51 differences between survivors and nonsurvivors were significant at each time interval, whereas pH differences were significant at 2 hours in the moderate group and at 2, 16, and 24 hours in the severe group. @entity1 who failed to improve their @entity51 > -6 had an increased frequency of adult @entity649 , @entity881 , and mortality. CONCLUSION: Base deficit reveals differences in metabolic @entity520 between survivors and nonsurvivors not shown by pH determinations and is clearly a better marker of @entity520 clearance after shock.
