Hemodynamic Perturbations in Deep Brain Stimulation Surgery: First Detailed Description.

Area of Science:

• Neurosurgery
• Anesthesiology
• Cardiology

Background:

• Hemodynamic perturbations are anticipated during deep brain stimulation (DBS) surgery.
• Acute hemodynamic changes can lead to severe complications like intracranial bleeding, stroke, and myocardial infarction.
• Understanding the incidence and risk factors of these perturbations is crucial for patient safety.

Purpose of the Study:

• To determine the incidence rate of hemodynamic perturbations during DBS surgery.
• To identify risk factors associated with these intraoperative hemodynamic changes.
• To analyze the effect of perioperative variables on hemodynamic stability.

Main Methods:

• Retrospective study of patients undergoing DBS surgery over 10 years.
• Collection of demographic and procedural characteristics.
• Analysis of intraoperative hemodynamic changes using a regression model.

Main Results:

• The overall rate of hemodynamic adverse events during DBS surgery was 10.8 (range: 0-42).
• These events required treatment in 57% of cases.
• Baseline blood pressure (systolic, diastolic, and mean arterial pressure) showed a highly significant effect on intraoperative hemodynamic perturbations.

Conclusions:

• Baseline blood pressure is a critical predictor of intraoperative hemodynamic perturbations in DBS surgery.
• Monitoring and managing baseline blood pressure are essential for mitigating risks during DBS procedures.
• Further research may explore specific management strategies for blood pressure control in DBS patients.
