Review Meta Analysis
Efficacy and safety of subdural drains after burr-hole evacuation of chronic subdural hematomas: systematic review and meta-analysis of randomized controlled trials.
To determine whether the use of a subdural drain after burr-hole evacuation of a chronic subdural hematoma is safe and effective in preventing recurrence and subsequent operations, and as such improving functional outcomes. ⋯ The meta-analysis demonstrates that the insertion of a subdural drain was associated with a statistically significant reduction in the risk of symptomatic recurrence and the requirement for further surgical intervention of chronic subdural hematoma after surgical evacuation. Furthermore, it was associated with statistically significant improvements in both short-term and long-term functional outcome.
