PECARN pediatric IAI (Holmes 2013)
PECARN pediatric IAI (Holmes 2013). Very low risk of IAI requiring acute intervention only when all seven caller-assigned findings are absent: abdominal wall trauma or seatbelt sign, GCS <14, abdominal tenderness, thoracic wall trauma, abdominal pain, decreased breath sounds, and vomiting. Presence of a criterion does not mandate CT. Not a diagnosis. Not PECARN head. magent does not examine the patient.
