Comparative study between shock index and assessment of blood consumption score in polytrauma patients as a predictor of massive blood transfusion

Background Hemorrhagic shock is the primary cause of preventable mortality in polytrauma patients, accounting for 50% of mortalities within 24 h of hospital admission. Aim To evaluate the predictive value of the shock index (SI) and the assessment of blood consumption (ABC) score in polytrauma patients concerning the need for a massive blood transfusion (MBT). Patients and methods This was a prospective comparative study conducted on 300 polytrauma patients who were transported directly to the Emergency Department at Tanta University Hospital. Ninety-one patients needed MBT due to chest and abdominal trauma according to the SI and ABC score, and 209 patients did not need MBT. Results SI can significantly predict massive blood need (area under the curve=0.957 and P
