Initial Loss of Consciousness and Risk of Delayed Cerebral Ischemia After Aneurysmal Subarachnoid Hemorrhage
Why the study?
Does loss of consciousness for >1 hour predict delayed cerebral ischemia in patients with aneurysmal subarachnoid hemorrhage?
Population
125 consecutive patients admitted within 4 days after aneurysmal subarachnoid hemorrhage
Comparison
Loss of consciousness for >1 hour after hemorrhage vs No loss or <1-hour loss of consciousness
Design

Implication
Prolonged LOC may flag aSAH patients for intensified DCI monitoring; leaves open whether it refines risk models or guides interventions.
Structured PICO

P
Population
125 consecutive patients admitted within 4 days after aneurysmal subarachnoid hemorrhage
I
Intervention
Loss of consciousness for >1 hour after hemorrhage
C
Comparator
No loss or <1-hour loss of consciousness
O
Outcome
Development of delayed cerebral ischemia (DCI)hard clinical
Duration of unconsciousness >1 hour after aneurysmal subarachnoid hemorrhage is a strong predictor for the occurrence of delayed cerebral ischemia.
