Abstract

Purpose: PL, creatinine and urine output are biomarkers of the suitability and prognosis of fluid therapy in severe burn
patients. The purpose of this study is to evaluate the usefulness of predicting mortality by biomarkers and its change during initial fluid therapy for severe burn patients.
Methods: A retrograde review was performed on 733 patients from January 2014 to December 2018 who were admitted as
severe burn patients to our burn intensive care unit (BICU). Plasma lactate, serum creatinine and urine output were measured at the time of admission to the BICU and after 48 hours. ABSI score, Hangang score, APACHEII, revised Baux index and TBSA were collected after admission.
Results: 733 patients were enrolled. PL was the most useful indicators for predicting mortality in burn patients at the time of
admission (AUC: 0.813) and after 48 hours (AUC: 0.698). On the other hand, mortality prediction from initial fluid therapy for
48 hours showed different results. Only creatinine showed statistical differences (P<0.05) in mortality prediction. But there
were no statistical differences in mortality prediction with PL and UO (P>0.05).
Conclusion: In this study, PL was most useful predictor among biomarkers for predicting mortality. Improvement in creatinine levels during the first 48 hours is associated with improved mortality. Therefore, efforts are needed to improve creatinine levels.
