BackgroundChronic subdural hematoma (CSDH) is a neurosurgical pathology of an aged populace. Pathogenetic risk factors include traumatic brain injury, prolonged use of antiplatelet drugs, hypertension, and some inflammatory processes. The incidence increases as patients age. Burr-hole evacuation is the most common approach in management of symptomatic cases. We compared evacuation of chronic subdural hematomas with general or local anesthesia (GA and LA, respectively) and evaluated the safety, economic benefits, effects of comorbidity, benefits, and shortcomings of both techniques.MethodsWe conducted a retrospective study of 67 consecutive patients who had 74 procedures for CSDH in a single neurosurgical center, the Regional Clinic, Centre of Neurosurgery and Neurology, over a 3-year period. They were grouped into the GA group (n = 44) and LA group (n = 23). Mean duration of procedure, length of hospital stay, complications, and preoperative and postoperative neurologic statuses were compared. The distribution of nominal variables between groups was compared using the Fisher exact test. The average duration of operation and length of hospital stay were compared using the Mann-Whitney U-test due to violation of the normality assumption.ResultsLA proved to be as effective as GA in CSDH evacuation. Seventy-four surgical procedures were performed on 67 patients due to recurrence in less than 30 days in 7 patients. Fifteen patients had tension pneumocephalus managed with fluid therapy to full recovery. LA was economical and required shorter hospital stays and surgical time.ConclusionsIn our studies, LA proved to be noninferior to GA, time conserving, and less prone to some of the adverse effects of GA on elderly patients with comorbidity, although some patients who are hyperactive or contraindicated to LA will require GA.Copyright © 2023 Elsevier Inc.
