SUMMARY
ROLE OF SHOCK INDEX IN PREDICT
MORTALITY IN BURN SEVERE PATIENTS
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.
