PedSRC Rule for Blunt Abdominal Trauma
Identifies children at very low risk of intra-abdominal injury.
PedSRC Rule for Blunt Abdominal Trauma
Hypotension for age
Abnormal abdominal exam (wall trauma, tenderness or distension)
AST >200 U/L
Haematocrit <30%
Abnormal pancreatic enzymes (elevated amylase or lipase)
Microscopic haematuria (>5 RBC/hpf)
ResultVery low risk
No variables present. Risk of intra-abdominal injury is about 1% (NPV ~98.8%); abdominal CT can often be avoided.
- Variables present
- 0 of 6
When to use
- Deciding whether abdominal CT can be safely avoided in a haemodynamically evaluable child after blunt abdominal trauma.
Formula
Six high-risk variables: hypotension for age, abnormal abdominal exam, AST >200 U/L, haematocrit <30%, abnormal pancreatic enzymes, microscopic haematuria. Absence of all = very low risk.
Pearls and pitfalls
- The rule identifies who can avoid CT; it is not intended to mandate CT when a variable is present.
