Brief summary

A systolic blood pressure (SBP) lower than the heart rate (HR) could indicate a poor condition in trauma patients. In such scenarios, the reversed shock index (RSI) is \<1, as calculated by the SBP divided by the HR. This study aimed to clarify whether RSI could be used to identify high-risk adult patients with isolated traumatic brain injury (TBI).

Interventions

OTHERreversed shock index < 1

Among patients with isolated TBI, those with an RSI \< 1 had higher mortality

OTHERreversed shock index ≥ 1

Among patients with isolated TBI, those with an RSI ≥ 1 had lower mortality
