Predictive value of shock index ≥ 1 in severe trauma patients in emergency department (original) (raw)

La Tunisie medicale, 2019

Abstract

BACKGROUND the shock index (SI) defined by the ratio of systolic blood pressure to heart rate was demonstrated as a simple tool in the triage and orientation of severe trauma patients to trauma centers. AIM To assess the prognostic value of the SI ≥ 1 in terms of mortality in severe trauma patients admitted to the emergency room. METHODS We performed a prospective, observational and descriptive study with the inclusion of severe trauma patients over the age of 18 years admitted to the Vital Emergency Room over a 21-month period. SI was calculated at admission: SI = heart rate / systolic blood pressure, a SI threshold value ≥1 was fixed to define two groups: SI<1 and SI≥1. RESULTS A total of 290 trauma patients were included, 231 (79%) had a SI<1, whereas 59 (21%) had an SI≥1. Mean age was 43.5 ± 18 years, 82% were male. There was a significant difference in hospital mortality at 7 days and at 30 days between the two groups respectively (group SI<1 vs group SI≥1): [12% vs 40...
