Plain-language summary

The study aimed to evaluate the effects of 24-Hour-Call-associated acute partial sleep deprivation on surgical residents' technical and cognitive performance in a virtual reality (VR) setting. Physiological parameters were used to quantify fatigue in respect to hours of sleep and subjective degrees of sleepiness. Technical performance and cognitive skills were assessed through low- and high fidelity tasks usig the VR- simulator LapSim. Objective alertness was measured by the standardized d2-Paper-Pencil-Test.
