Vasospasm management: a meta-synthesis of current modalities used by different medical societies
Year: 2024
Type: article
Abstract: Background: Cerebral vasospasm is a life-threatening complication of an aneurysmal subarachnoid hemorrhage (aSAH), with approximately 6 to 10 cases per 100,000 patients yearly. Despite the publication of numerous guidelines from various medical societies, there is a lack of standardized consensus on what the optimal management strategies for this severe complication truly are. This meta-synthesis aims to synthesize these endorsed recommendations to ultimately identify standardized care guidelines and improve patient outcomes after aSAH. Methods: A comprehensive database search of existing guidelines published by major medical societies in the past 10 years was performed. Results: The analysis included 28 relevant documents from 7 major medical societies. Key findings included: 1) Unanimous endorsement for oral nimodipine administration for 21 days post-aSAH. 2) Varying recommendations for alternative calcium channel blockers and hemodynamic management methods. 3) Targeted hypermagnesemia and routine statin therapy were not universally recommended due to insufficient evidence. 4) Use of antifibrinolytics was considered on a case-by-case basis. 5) Endovascular interventions were recommended for refractory cases, specifically. Conclusion: This meta-synthesis reveals consistencies and divergences in vasospasm management recommendations across medical societies, highlighting the need for more robust clinical trials, regular guideline updates, and increased medical society collaboration.
