Management of Recurrent Tylenol-Responsive Fevers in Posterior Fossa SAH
Understanding Fever in SAH
- Fever in SAH patients is common and can be of both infectious and non-infectious (central) origin, with fever associated with severity of injury, amount of hemorrhage, and development of vasospasm, potentially representing a systemic inflammatory response triggered by blood and its byproducts 2
- Fever is independently associated with worse cognitive outcomes in survivors of SAH 2
Management Approach
- Acetaminophen should be used as the first-line antipyretic for managing recurrent fevers in patients with posterior fossa subarachnoid hemorrhage (SAH), with aggressive fever control targeting normothermia 1
- Administer acetaminophen regularly rather than sporadically when fevers recur, to maintain normothermia 1
- Aggressive control of fever to achieve normothermia is reasonable in the acute phase of SAH (Class IIa; Level of Evidence B) 1
Monitoring and Workup
- Investigate for potential infectious causes of fever (pneumonia, urinary tract infection, line infections) 4
- Monitor for development of vasospasm, as fever has been chronologically associated with onset of sonographic and clinical vasospasm 2
- Implement standardized ICU care bundles for patients requiring mechanical ventilation to reduce hospital-acquired pneumonia, which can be a source of fever 3
Additional Considerations
- Maintain euvolemia through close monitoring and goal-directed treatment of volume status 3
- Manage hyponatremia, which is common in SAH patients, with mineralocorticoids if needed 3
- Consider effective glycemic control and strict hyperglycemia management, as hyperglycemia is associated with poor outcomes 3
