Trauma Patients Had Not Received Blood Transfusion = 10 U Clinical Trial
Official title:
The Relationship of Delta Shock Index With the Requirement of Blood Transfusion and Clinical Outcome of Adult Trauma Patients
Background: To determine the performance of delta shock index (ΔSI), a change in shock index
(SI) upon arrival at the emergency room (ER) from that in the field in predicting the need
for massive transfusion (MT) among adult trauma patients with stable blood pressure.
Methods: This study included data from all trauma patients aged 20 years and above who were
hospitalized from January 1, 2009 to December 31, 2016 and was obtained from the registered
trauma database of the hospital. Only patients who were transferred by emergency medical
service from the accident site with a systolic blood pressure ≥ 90 mm Hg at the ER were
included in this study. The 7,957 enrolled trauma patients were divided into 2 groups, those
who had received blood transfusion ≥ 10 U (MT, n = 82) and those who had not (non-MT, n =
7,875). The odds ratios with 95% confidence intervals for associated patient conditions and
the odds of need for MT by a given ΔSI were measured. The plot of specific receiver operating
characteristic (ROC) curves was used to evaluate the best cutoff point that could predict the
patient's probability of receiving MT.
