This review article explores the underlying pathophysiology that causes increased intracranial pressure (ICP) during hospitalization. Hydrocephalus, brain swelling, and intracranial hematoma could produce an ICP rise. Although cerebrospinal fluid withdrawal via an external ventricular drain is commonly used, ICP monitoring is not always consistently practiced. Indications for ICP monitoring include neurological deterioration, hydrocephalus, brain swelling, intracranial masses, and the need for cerebrospinal fluid drainage. This review emphasizes the importance of ICP monitoring and presents findings from the Synapse-ICU study, which supports a correlation between ICP monitoring and treatment with better patient outcomes. The review also discusses various therapeutic strategies for managing increased ICP and identifies potential areas for future research.<\/jats:p>","DOI":"10.1007\/s12028-023-01752-y","type":"journal-article","created":{"date-parts":[[2023,6,6]],"date-time":"2023-06-06T20:29:12Z","timestamp":1686083352000},"page":"59-69","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":65,"title":["Intracranial Pressure Monitoring and Management in Aneurysmal Subarachnoid Hemorrhage"],"prefix":"10.1007","volume":"39","author":[{"given":"Alberto","family":"Addis","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marta","family":"Baggiani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5374-3161","authenticated-orcid":false,"given":"Giuseppe","family":"Citerio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,6,6]]},"reference":[{"key":"1752_CR1","doi-asserted-by":"publisher","first-page":"1201","DOI":"10.1212\/CON.0000000000001052","volume":"27","author":"SH-Y Chou","year":"2021","unstructured":"Chou SH-Y.
