Patient selection: recent aneurismal subarachnoid hemorrhage
Predictors for cerebral infarction on multivariate analysis:
(1) older age (>= 60 years)
(2) worse neurological grade on admission (World Federation of Neurological Surgeon = WFNS Grade 3, 4 or 5)
(3) history of hypertension
(4) history of diabetes mellitus
(5) greater diameter of the aneurysm (>= 13 mm)
(6) hypertension induced prophylactically or therapeutically
(7) temperature on day 8 after the SAH > 38°C
(8) presence of symptomatic vasospasm
where:
• The rise in temperature on day 8 may be a sign of vasospasm.
Avoiding vasospasm may be one way to improve outcome.
