Abstract

Abstract

Objective: To evaluate the association between diastolic blood pressure and massive transfusion in severe trauma.

Methods: The retrospective study was conducted at a tertiary emergency medical centre in Gwangju , Republic of Korea, and comprised data of severe trauma patients with injury severity score >15 presenting between January 2016 and December 2017. Multivariate logistic regression analysis was performed to evaluate the association between diastolic blood pressure and massive transfusion. Receiver operating characteristic curve analysis was performed to estimate the prognostic performance of diastolic blood pressure. Data was analysed using SPSS 18.

Results: Of the 827 patients, 64(7.7%) underwent massive transfusion. After adjusting the confounders, diastolic blood pressure was found to be an independent factor in predicting massive transfusion (odds ratio: 0.965; 95% confidence interval: 0.956–0.975).

Conclusion: Initially low diastolic blood pressure was found to be an independent predictor for massive transfusion in severe trauma cases.

Key Words: Trauma, Diastolic blood pressure, Massive transfusion.
