Abstract

Objectives: To evaluate the role of Shock Index in predict mortality in burn severe patients. Subjects and methods: A retrospective study was conducted on 273 adult burn patients (16 – 65) with burn extent


≥ 30% total body surface area (TBSA) hospitalized within 6 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 shock index. Using ROC test to analyze the mortality prognostic value of factors. Results: The mortality rate was 29.48%. The majority of patients with increased SI (72.83%). Compared with the surviving group, the mortality group had significantly greater shock index, modified shock index and age shock index (p < 0=0.0001). In contrast, the reverse shock index was lower in the mortality group than in the surviving group, the difference was statistically significant (p = 0.0001). Multivariate analysis showed that the age shock index with thickness of burn area and inhalation injury was independently associated with mortality. Combining the age shock index with thickness of burn area and inhalation injury has a very good predictive value of mortality (AUC = 0.95; sensitivity 88.16%; specificity 90.15%), significantly higher than for each factor alone (p = 0.0001). Conclusion: The age shock index with thickness of burn area and inhalation injury are independent predictors of mortality in burn patients. The predictive value of mortality of age shock index with thickness of burn area and inhalation injury is very good.
