This noninferiority randomized controlled trial evaluated the effects of general anesthesia versus conscious sedation on microelectrode recording quality during deep brain stimulation surgery for Parkinson's disease. Among 188 patients, general anesthesia demonstrated noninferior high-quality recording rates (89.4% vs 90.3%) and reduced operative time by 9.07 minutes, suggesting it is a valid alternative to conscious sedation.
Key findings
- High-quality microelectrode recording was achieved in 89.4% of the general anesthesia group compared to 90.3% in the conscious sedation group.
- General anesthesia reduced operative time by 9.07 minutes compared to conscious sedation.
- At 6 months, changes in Unified Parkinson's Disease Rating Scale scores were comparable between groups.
- Complication rates were similar: 10.9% for general anesthesia vs 8.9% for conscious sedation.
Why it matters
Understanding the impact of anesthesia choice on intraoperative outcomes is crucial for optimizing surgical procedures in Parkinson's disease. This study provides evidence that general anesthesia can be as effective as conscious sedation, potentially improving surgical efficiency.
