Half-Saline Versus Normal-Saline as Irrigation Solutions in Burr Hole Craniostomy to Treat Chronic Subdural Hematomata: A Randomized Clinical Trial

Intraoperative Irrigation and Risk of Chronic Subdural Hematoma Recurrence

“…8 The effect of irrigation fluid composition, including saline, half-saline, and artificial cerebrospinal fluid, on recurrence rates has yielded inconsistent findings, with similar rates observed across different compositions. 9,10 Furthermore, one study showed that irrigation could be omitted without increased recurrence rate, 11 and questionnaire surveys among neurosurgeons have suggested that 3% do not use irrigation at all. 8 The technique of burr hole placement during CSDH evacuation varies between a single or multiple holes, influenced by surgeon preference, protocols, and perceived outcomes.…”
