Why the study?
On-call shifts are linked to impaired cognition and alertness, but whether sleep deprivation reduces regional cerebral oxygen saturation (rScO2) was unknown.
Does sleep deprivation following 16-h nightshifts reduce cerebral oxygen saturation and cognitive function in pediatric residents?
Population
50 in-training pediatricians
Comparison
Nightshifts and continuous working without post-call day vs pre on-call baseline
Design
Prospective study
Follow-up
48-h
Key result
16-hour nightshifts among pediatric residents significantly reduced regional cerebral oxygen saturation (68.2% to 64.6%, p<0.001) and MoCA scores (28.4 to 27.7, p<0.001) at 24 hours.

Does sleep deprivation following 16-h nightshifts reduce cerebral oxygen saturation and cognitive function in pediatric residents?
Absolute Event Rate: 64.6% vs 68.2%
p-value: p=<0.001
Extended 16-hour nightshifts without a post-call day cause transient reductions in cerebral oxygen saturation and cognitive function in pediatric residents.
Junsawat et al. (2023) conducted an observational in Sleep deprivation (n=50). 16-hour nightshifts and continuous working vs. Pre on-call baseline was evaluated on Regional cerebral oxygen saturation (rScO2) at 24 hours from pre on-call (p=<0.001). 16-hour nightshifts among pediatric residents significantly reduced regional cerebral oxygen saturation (68.2% to 64.6%, p<0.001) and MoCA scores (28.4 to 27.7, p<0.001) at 24 hours.
