Previous studies have explored the effect of fatigue on general psychomotor proficiency. However, studies specifically addressing the effect of fatigue on surgical residents' cognitive skills during simulated surgical exercises are lacking. ⋯ Fatigue and sleep deprivation cause a significant deterioration in the surgical residents' cognitive skills as measured by virtual reality simulation. Psychomotor skills are also negatively impacted during tasks that require a combination of psychomotor and cognitive skills.

Bronchoalveolar lavage (BAL) is recommended to facilitate the diagnosis of ventilator-associated pneumonia (VAP). It is unclear if bilateral sampling improves the accuracy of BAL. ⋯ Bilateral BAL improves the accuracy of bronchoscopy in diagnosing VAP. Unilateral BAL may be insensitive in patients with clinically significant contralateral infection.
