- This validation study found that the Pediatric Emergency Care Applied Research Network (PECARN) rule accurately rules out clinically important intra-abdominal injuries (CIIAI) in children who have sustained blunt abdominal trauma (BAT).
- Prospective multicenter study needed.
Why this matters
- This study seeks to validate PECARN’s rule to predict which children do not require CT after BAT.
- Rule weighs 7 factors: evidence of abdominal wall trauma or seatbelt sign, Glasgow coma score, abdominal tenderness, thoracic wall trauma, abdominal pain, breath sounds, and vomiting.
- 1 patient with CIIAI would have been deemed very low risk by the PECARN rule; this patient had extra-abdominal arterial bleeding.
- Sensitivity: 99% (95% CI, 95.9-100).
- Single-center retrospective registry study of 5743 pediatric trauma patients at a level 1 trauma center, 133 with CIIAI.
- Outcome: sensitivity of PECARN prediction rule.
- Funding: None.
- Small study.
- Criteria not designed to rule out pelvic and/or spinal injuries.
