Summary Background Data:
The effect of acute partial sleep deprivation on surgical proficiency is still controversially discussed. The present study is the first to measure objective physiological parameters of fatigue in respect to subjective perceptions of sleepiness in VR- research of surgical performance.
38 surgeons were explored on three consecutive mornings: prior to a 24-Hour- Call, post-call and after 24 hours resting. Hours of sleep were recorded. Subjective alertness was assessed using the standardized Stanford-Sleepiness-Scale (SSS). Saliva cortisol concentrations and pupillary activity were measured by ELISA and pupillography. The VR-simulator LapSim® was used to assess technical skills through defined low- fidelity VR-tasks "cutting", "clip applying" and cognitive skills through defined high-fidelity VR-tasks "intracorporal suturing", "VR-cholecystectomy". Objective alertness was measured by the standardized d2-Paper-Pencil-Test.

- Technical and cognitive performance [ Time Frame: 3 days ]Technical and cognitive performance was assessed in a VR-setting of defined parameters of performance and the d2-Paper-Pencil-Test on three consecutive mornings- pre- and post call and after 24 hours resting.
- Sleepiness and Fatigue [ Time Frame: 4 months ]Sleepiness was assessed by Stanford Sleepiness Sclae (SSS) and fatigue was measured through pupillography and saliva cortisol concentration on three consecutive mornings- pre- and post call and after 24 hours resting.
