PROGNOSTIC VALUES OF NEUTROPHIL/LYMPHOCYTE RATIO IN SEVERE BURN PATIENTS.

The aim of this study was to evaluate the characteristics and prognostic value of the neutrophil/lymphocyte ratio (NLR) in patients with severe burns. A retrospective study was conducted on 245 burn patients over 18 years old without comorbidity or combined injury, burn extent =20% TBSA, hospitalized within 24 hours after burn. The collected criteria included patient characteristics, NLR on admission, 3rd and 7th day after burn, and outcome. The results showed that NLR was higher than the normal value at all collected times. In addition, compared to the survivor group, NLR on admission, 3rd and 7th day after burn was significantly higher in the mortality group (p <.01). Multivariate analysis found that the NLR on the 7th day postburn was an independent factor associated with mortality (p <.05), along with the increase in age, burn extent, and presence of inhalation injury (AUC = .85; cut off: 14.13; sensitivity: 75% and specificity: 83.43%). In conclusion, NLR on the 7th day post burn may be used as a predictive factor for mortality amongst severe burn patients. [ABSTRACT FROM AUTHOR]
