[Stereotaxy during intravenous anesthesia with propofol]

Area of Science:

• Neurosurgery
• Anesthesiology
• Neurology

Context:

• Stereotactic surgery is a key treatment for movement disorders.
• Intravenous propofol anesthesia is increasingly used in neurosurgery.
• Evaluating anesthetic techniques is crucial for patient safety and surgical success.

Purpose:

• To assess the efficacy and safety of intravenous propofol anesthesia during stereotactic surgery for movement disorders.
• To evaluate the impact of propofol on patient outcomes, including motor function and activities of daily living (ADL).
• To determine the utility of propofol anesthesia in wake-up tests for neural noise recording and target identification.

Summary:

• A retrospective review of 30 patients undergoing stereotactic surgery for movement disorders under propofol anesthesia showed significant improvements in motor and ADL scores for Parkinson's disease patients.
• Propofol anesthesia facilitated wake-up tests for neural noise recording, aiding target identification, and tremor suppression in 17 patients.
• Adverse events were minimal, with one allergic reaction; however, three juvenile parkinsonian patients experienced dopa-induced dyskinesia (DID) during propofol infusion, suggesting a potential anti-parkinsonian effect.

Impact:

• Intravenous propofol anesthesia is a safe and effective anesthetic method for stereotactic surgery in movement disorders.
• Propofol facilitates intraoperative monitoring and potentially offers therapeutic benefits for Parkinson's disease symptoms.
• The findings support the continued use of propofol in stereotactic neurosurgery, optimizing patient care and surgical outcomes.
