What are the potential harms associated with induced hypotension during cerebral aneurysm surgery?
Induced hypotension has been used in the past to prevent aneurysm rupture, however data suggest that there could be potential harm, with an increased risk of early and delayed neurological deficits. A retrospective study suggests that a decrease in mean arterial pressure of 50% is associated with poor outcome, however after adjustment for age, this association was no longer statistically significant.
