Abstract
Elevated blood alcohol content (BAC) on admission is associated with poorer outcomes, larger burns and more inhalation injury. This study's purpose was to examine the effects of alcohol through a matched case-controlled study, measuring early and extended markers of clinical outcomes. The hypothesis was that patients with an elevated admission BAC would require more resuscitation and have a longer hospital stay. Admissions 16 to 75 years of age with 15 to 75% TBSA and admission BACs were identified. Patients with BAC >30 mg/dl (BAC+, cases) were matched with patients with undetectable BAC (BAC-, controls), according to age, sex, TBSA, inhalation injury and mechanism. Screening identified 258 patients, 146 with admission BACs. Twenty-seven had a BAC > or = 30 mg/dl. There were 24 matched pairs. At 24 hours, BAC+ group had larger acute physiology and chronic health evaluation II scores (23.33 vs 18.75, P < .05), fluid requirements (5.25 vs 3.82 L (cc/kg/TBSA), P < .05), and base deficit (11.15 vs 7.15, P < .05). The duration of mechanical ventilation (14.85 vs 4.23 days, P < .05), intensive care unit length of stay (22.85 vs 9.38, P < .05), hospital length of stay (28.95 vs 15.68, P < .05), and mean hospital charges ($239,507 vs $144,598, P < .05) were increased in the BAC+ patients. Despite matched baseline injury characteristics, elevated BAC was associated with poorer short term and extended clinical outcomes, illustrating the impact of alcohol intoxication on physiologic derangement after burn injury.
