🚑 Pediatric Trauma BIG Score

UseWhen to use: injured children at admission when BD, INR, and GCS are available.

StrataHigher BIG → higher mortality band; often <12 lower and >16 higher in literature cues.

LimitsWhen not to use: as sole futility criterion. · Pitfall: entering base excess signed negative instead of deficit magn… · Pair with PTS/SIPA and ABCs.

Clinical takeaway

BD + 2.5×INR + (15−GCS).

When to use

When to use: injured children at admission when BD, INR, and GCS are available.

How it works

BIG = base deficit + 2.5×INR + (15 − GCS).

Key points

  • BD + 2.5×INR + (15−GCS).
  • Admission labs/GCS.
  • Next: trauma bay resuscitation.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
