Abstract

Objective

To compare the ability of serum lactate levels and Revised Trauma Score (RTS) in predicting 24-hours mortality in hemodynamically unstable multi-trauma patients.

Study design

Cross-sectional analytic study.

Place & Duration of study

Dr. Ruth K. M. Pfau Civil Hospital Karachi, from February 2022 to August 2022

Methods

A total of 222 patients of 18 to 75-years of age who presented in the Emergency Department with multi-trauma were enrolled. The outcome variables noted were lactate level, Revised Trauma Score and mortality. All the collected data were entered into SPSS version 20 and analyzed. 

Results

The mean age of the patients was 40.67±12.5 years. There was a male preponderance (n=170 – 76.6%). The most common mechanism of injury was stabbing (n=80 - 36%). The 24-hours’ mortality among patients with multi-trauma was 6.8% (n=15) and the area under the curve of lactate levels and Revised Trauma Score in predicting 24-hours mortality were 0.497 and 0.451 respectively. The findings were statistically insignificant.

Conclusion

In patients with multi-trauma the lactate level and Revised Trauma Score were not reliable in predicting the 24-hours mortality.
