HealthDay News — Partial sleep deprivation following a night-call shift affects anesthesiologists’ total mood status and their cognitive skills, according to a study published in the Pediatric Anesthesia.

Haleh Saadat, MD, from Nationwide Children’s Hospital in Columbus, Ohio, and colleagues evaluated the impact of partial sleep deprivation after a 17-hour overnight call (3 p.m. to 7 a.m.) on the mood status and cognitive skills of 21 pediatric anesthesiologists in an academic clinical hospital setting, compared to when working regular hours. The Profile of Mood States was used to assess six mood states between 7 a.m. and 8 a.m., with a total score providing a global estimate of affective state.
