Background: Subarachnoid hemorrhage patients are hypermetabolic and at risk for developing medical complications. A relationship was hypothesized between energy balance and complications following subarachnoid hemorrhage. Methods: Fifty-eight consecutive poor-grade subarachnoid hemorrhage patients (mean age, 58; range, 26-86; 66% women) were studied between 2005 and 2007. Caloric intake and energy expenditure were assessed. In-hospital complications over the first 14 days posthemorrhage were defined as renal failure, fever (>38.3°C), any infection, anemia, hyperglycemia (>11 mmol/L), and myocardial infarction. Energy balance was calculated by subtracting energy expenditure from caloric intake. Results: Enteral nutrition was begun 1 day posthemorrhage (range, 0-5 days). Recommended (mean ± SD) caloric intake was 28 ± 3 kcal/kg/d, and the actual was 14 ± 5 kcal/kg/d. Enteral nutrition accounted for 67% of caloric intake; propofol and dextrose infusions accounted for 33% of caloric intake. Cumulative energy balance over the first 7 days was -117 ± 53 kcal/kg. The average energy balance during the first 7 days after subarachnoid hemorrhage significantly correlated with the total number of infectious complications (r = -0.5, P <.001) but not medical complications (r = -0.2, P =.1). After adjustment for Hunt-Hess grade, fever, hyperglycemia, and anemia, negative energy balance during the first 7 days after subarachnoid hemorrhage correlated with the number of infectious complications (P =.01). Conclusions: Infectious complications after subarachnoid hemorrhage are associated with negative energy balance. Studies are needed to better understand the impact of negative energy balance on outcome after subarachnoid hemorrhage.
