Systemic complications of subarachnoid hemorrhage from spontaneous rupture of a cerebral aneurysm

Systemic complications secondary to subarachnoid hemorrhage from an aneurysm are common (40%) and the mortality attributable to them (23%) is comparable to mortality from the primary lesion, rebleeding, or vasospasm. Although nonneurologic medical complications are avoidable, they worsen the prognosis, lengthen the hospital stay, and generate additional costs. The prevention, early detection, and appropriate treatment of systemic complications will be essential for managing the individual patient's case. Treatment should cover major symptoms (headache, nausea, and dizziness) and ambient noise should be reduced, all with the aim of achieving excellence and improving the patient's perception of quality of care.
