Multicenter Study
Association of Traumatic Brain Injuries With Vomiting in Children With Blunt Head Trauma.
We aimed to determine the prevalence of traumatic brain injuries in children who vomit after minor blunt head trauma, particularly when the vomiting occurs without other findings suggestive of traumatic brain injury (ie, isolated vomiting). We also aimed to determine the relationship between the timing and degree of vomiting and traumatic brain injury prevalence. ⋯ Traumatic brain injury on CT is uncommon and clinically important traumatic brain injury is very uncommon in children with minor blunt head trauma when vomiting is their only sign or symptom. Observation in the emergency department before determining the need for CT appears appropriate for many of these children.
