Clinical Scorecard: Physiological Factors Associated with Surgeon Stress During Live Robot-Assisted Surgical Procedures
At a Glance
| Category | Detail |
|---|
| Condition | Surgeon Stress During Robot-Assisted Surgery |
| Key Mechanisms | Cognitive and psychomotor burden, physiological subsystems engagement |
| Target Population | Urologic surgeons with robotic console experience |
| Care Setting | Intraoperative environment during live RAS procedures |
Key Highlights
- Surgeon stress impacts attention, motor control, and team communication.
- Perceived stress is a dynamic state with measurable psychophysiological correlates.
- Multimodal physiological measurement may better characterize perceived stress.
- Study conducted at Chiba University Hospital with urologic surgeons.
- Data collected using the da Vinci Xi Surgical System.
Guideline-Based Recommendations
Diagnosis
- Assess perceived stress through multimodal physiological recordings.
Management
- Implement workflow-compatible approaches for intraoperative stress assessment.
Monitoring & Follow-up
- Utilize electroencephalography, electromyography, and electrocardiography for real-time monitoring.
Risks
- Excessive stress may compromise surgical performance and safety.
Patient & Prescribing Data
Patients undergoing elective RAS procedures.
Surgeons must manage stress to optimize performance.
Clinical Best Practices
- Conduct stress assessments in real surgical environments rather than simulations.
- Use hierarchical mixed-effects models to analyze physiological data.
