Adverse events were more common with less experienced residents and greater injury severity.Thursday’s Spoon Feed:No single symptom or exam finding definitively diagnoses pediatric concussion, but mental fog, light/noise sensitivity, nausea, and oculomotor abnormalities meaningfully increase likelihood, while absence of headache decreases it.

However, while it offers high diagnostic accuracy, emergency physicians should use it as one prognostic marker among others rather than a sole reason to terminate efforts.Tuesday’s Spoon Feed:Of patients with return of spontaneous circulation (ROSC) after in-hospital cardiac arrest (IHCA), CT imaging revealed new findings 65.2% of the time while POCUS did so in 57.6% of IHCA patients.
