Randomized Controlled Trial
The utility of high-flow oxygen during emergency department procedural sedation and analgesia with propofol: a randomized, controlled trial.
We determine whether high-flow oxygen reduces the incidence of hypoxia by 20% in adults receiving propofol for emergency department (ED) sedation compared with room air. ⋯ High-flow oxygen reduces the frequency of hypoxia during ED propofol sedation in adults.

Multicenter Study
Do children with blunt head trauma and normal cranial computed tomography scan results require hospitalization for neurologic observation?
Children evaluated in the emergency department (ED) with minor blunt head trauma, defined by initial Glasgow Coma Scale (GCS) scores of 14 or 15, are frequently hospitalized despite normal cranial computed tomography (CT) scan results. We seek to identify the frequency of neurologic complications in children with minor blunt head trauma and normal ED CT scan results. ⋯ Children with blunt head trauma and initial ED GCS scores of 14 or 15 and normal cranial CT scan results are at very low risk for subsequent traumatic findings on neuroimaging and extremely low risk of needing neurosurgical intervention. Hospitalization of children with minor head trauma after normal CT scan results for neurologic observation is generally unnecessary.
