Predictors of Toth et al for Pelvic Fracture-Related Arterial Bleeding (PFRAB)

Patient selection: trauma with pelvic fracture

Predictors for pelvic fracture related arterial bleeding:

(1) base deficit >= 6 mmol/L

(2) change in base deficit over 4 hours > 2 mmol/L (worsening of the acidosis)

(3) systolic blood pressure < 104 mm Hg

(4) need for transfusion in the Emergency Department

where:

• The change in base deficits is (initial base excess) - (second base excess)

Protocol:

(1) exclude chest, abdominal and extremity bleeding

(2) triage a trauma patient with these risk factors for pelvic hemorrhage control (angiography, pelvic packing)

Performance:

• The area under the ROC curve is 0.77.
