Abstract

Objectives: To evaluate the prognostic value of the arterial blood lactate combined with r-baux score and thickness of burn area to mortality in severe burn patients. Subjects and methods: A retrospective study was conducted on 241 burn patients over 16 years old with burn extent ≥ 20% total body surface area (TBSA) hospitalized within 24 hours postburn in the ICU, National Burn Hospital from 01/01/ 2021 - 31/10/2022. Patients were divided into two groups of survival and death, compared in terms of patient characteristics, burn features and arterial blood lactate levels on admission. Using ROC test to analyze the predictive value of mortality when combining the arterial blood lactate on admission with r-Baux score and thickness of burn area.
Results: The arterial blood lactate on admission was significantly higher (p < 0.001) in the death group compared with the survival group. Multivariate analysis showed that the arterial blood lactate on admission with r-Baux score and thickness of burn area was independently associated with mortality. Combining the arterial blood lactate on admission with r-Baux score and thickness of burn area has a very good predictive value of mortality (AUC = 0.923; sensitivity 81.97%; specificity 85.56%).
Conclusion: The predictive value of mortality of arterial lactate on admission in combination with the rBaux score and thickness of burn area is very good.
