  Purpose
The surgeons load during laparoscopic surgery is still unclear. Laparoscopic surgery is more demanding because of the challenge of operating through small scars in the abdominal wall without any tactile feedback depending only on the visual feedback on a monitor. The purpose is to establish a model of how to measure mental and physical load in laparoscopy.

Condition Intervention
Stress Device: Electrogram (EMG), heart rate variability (HRV), salivary cortisol, goniometry, inclinometry

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Official Title: Physical and Mental Load During Laparoscopic Tasks. A Prospective Randomized Trial of the Ergonomics in a Black Box Model

  • Goniometry
  • Inclinometry
  • HRV
  • Salivary Cortisol

Estimated Enrollment: 12
Estimated Study Completion Date: March 2007
Detailed Description:

The surgeons load during laparoscopic surgery is still unclear. Laparoscopic surgery is more demanding because of the challenge of operating through small scars in the abdominal wall without any tactile feedback depending only on the visual feedback on a monitor. Most studies have been conducted in laboratory set-ups: Black Box.

This study will establish a model of how to measure the biomechanical loads at muscular, joint and postural level, as well as measuring stress-hormone and cardiac rhythm. The study is a precursor of ergonomic studies performed inside the operating room. Advanced operating rooms designed specially for laparoscopy have been introduced in many departments. We do not know if they are more ergonomically correct. We will simulate laparoscopic tasks in an operating room. The hypothesis is that a traditional laparoscopic set-up is more demanding than a set-up mimicking an advanced operating room.
