Rass V, et al. - Among consecutive nontraumatic subarachnoid hemorrhage patients (n=237) admitted to the neurologic ICU between 2010 and 2016, researchers assessed the link between daily fluid intake and fluid balance with hospital complications and functional outcome in this retrospective observational cohort study. Participants were 57 years old (interquartile range, 47–67 yr old) and presented with a median admission Hunt and Hess grade of 3 (interquartile range, 1–5). In relation to higher daily fluid intake, they observed higher admission Hunt and Hess grade, increased pulmonary fluid accumulation, prolonged mechanical ventilation, higher daily Subarachnoid hemorrhage Early Brain Edema Score, occurrence of anemia, delayed cerebral ischemia, and poor functional outcome. Higher admission Hunt and Hess grade and anemia were seen in relation to daily fluid balance. Nutritional compounds (31%), IV drugs (30%), and volume substitution (17%) were the main contributors to fluids. Overall, fluid intake but not fluid balance was significantly related to hospital complications and poor functional outcome in subarachnoid hemorrhage patients.
