The use of the Shock Index as a predictor of active bleeding in trauma patients.

摘要: Abstract Introduction Vital signs indicate the presence of bleeding only after large amounts blood have been lost, with high morbidity and mortality. The Shock Index (SI) is a hemorrhage indicator cut-off point for risk at 0.9. aim this study to assess whether ≥0.8 more sensitive detecting occult bleeding, providing early initiation therapeutic maneuvers. Methods SI analytical validation severe trauma patients older than 16 years age. were recorded, scales predicting included: SI, Assessment Blood Consumption score, Pulse Rate Over Pressure score. relationship between 5 markers was analyzed: need massive transfusion, angiographic embolization, surgical control, death due hypovolemic shock, overall predictor “active bleeding” (defined as least one 4 above). Results Data from 1402 collected prospectively over period 10 years. mean Injury Severity Score 20.9 (SD 15.8). mortality rate 10%. 0.73 0.29). “Active present in 18.7% patients. area under ROC curve 0.749. Conclusions An ≥0.9 allows earlier resuscitation maneuvers active bleeding.
