Comparing Technical Dexterity of Sleep-Deprived Versus Intoxicated Surgeons

Comparing Technical Dexterity of Sleep-Deprived Versus Intoxicated Surgeons

BACKGROUND The evidence on the effect of sleep deprivation on the cognitive and motor skills of physicians in training is sparse and conflicting, and the evidence is nonexistent on surgeons in practice. Work-hour limitations based on these data have contributed to challenges in the quality of surgical education under the apprentice model, and as a result there is an increasing focus on competen...

Effect of sleep deprivation on surgeons' dexterity on laparoscopy simulator.

Simulation study of rested versus sleep-deprived anesthesiologists.

BACKGROUND Sleep deprivation causes physiologic and subjective sleepiness. Studies of fatigue effects on anesthesiologist performance have given equivocal results. The authors used a realistic simulation environment to study the effects of sleep deprivation on psychomotor and clinical performance, subjective and objective sleepiness, and mood. METHODS Twelve anesthesia residents performed a 4...

Chronically Sleep Deprived

Data from recent laboratory studies indicate that nocturnal sleep periods reduced by as little as 1.3 to 1.5 hours for 1 night result in reduction of daytime alertness by as much as 32% as measured by the Multiple Sleep Latency Test (MSLT). Other data document that 1) 170/0--57% of normal young adults have MSLT latencies of ::;5.5 minutes, whereas ::;50% have MSLT values of ~ 10 minutes and 2) ...

Surgeons' non-technical skills.

The importance of non-technical skills to surgical performance is gaining wide acceptance. This article discusses the core cognitive and social skills categories thought to underpin medical knowledge and surgical expertise, and describes the rise of non-technical skill models of assessment in surgery. Behavior rating systems such as NOTSS (Non-Technical Skills for Surgeons) have been developed ...
