Prognostic value of lactate to hematocrit ratio score in patients with severe thoracoabdominal trauma

BACKGROUND: Significant portion of trauma-related deaths occur in the 1st h; therefore, rapid diagnosis and adequate resuscita-tion in trauma patients are essential preventing mortality. In this study, we aimed to evaluate the role of lactate-to-hematocrite ratio (LHR) score for predicting mortality in patients with severe thoracoabdominal trauma.
METHODS: In this retrospective, cross-sectional study, we evaluated patients who applied to the emergency room between January 1, 2016, and December 31, 2019, due to multiple trauma. We measured the blood gas analysis values and LHR score of patients with severe thoracoabdominal trauma included in the study and investigated the effectiveness of the LHR score in predicting mortality.
RESULTS: 106 patients with severe thoracoabdominal trauma were included in the study. The 30-day mortality rate of the patients was 42.5% (n=45). Considering the 30-day mortality rates, the initial hematocrit, lactate, base deficit, and LHR score were statistically different between patients who died and survived. When the cutoff value for the LHR score was taken as 0.187 on the ROC curve to distinguish mortality, the sensitivity was found to be 77.8%, specificity to be 90.2%.
CONCLUSION: LHR score is an effective parameter with high sensitivity and specificity in predicting mortality in patients with severe thoracoabdominal trauma.

Ciddi torakoabdominal travma hastalarýnda laktat-hematokrit oranýnýn prognostik deðeri

AMAÇ: Travmaya baðlý ölümlerin önemli bir kýsmý ilk saatlerde olup, hýzlý taný ve yeterli resüsitasyon mortalitenin önlenmesinde büyük önem taþý-maktadýr. Bu çalýþmada, ciddi torakoabdominal travmalý hastalarda lactate-to-hematocrite ratio (LHR) skorunun mortaliteyi öngörmedeki rolünü deðerlendirmeyi amaçladýk.
GEREÇ VE YÖNTEM: Bu geriye dönük, kesitsel çalýþmamýzda 1 Ocak 2016–31 Aralýk 2019 tarihleri arasýnda acil servise çoklu travma nedeniyle baþvuran hastalarý deðerlendirdik. Çalýþmaya alýnan ciddi torakoabdominal travmalý hastalarýn kan gazý analiz deðerlerini ve LHR skorunu ölçtük ve LHR skorunun mortaliteyi öngörmedeki etkinliðini araþtýrdýk.
BULGULAR: Ciddi torakoabdominal travmalý 106 hasta çalýþmaya alýndý. Hastalarýn 30 günlük mortalite oraný %42.5 (n=45) idi. Hastalarýn 30 gün-lük mortaliteye göre ölenlerle kurtulanlar arasý baþlangýç hematokrit, laktat, baz açýðý ve LHR skoru istatistiksel olarak farklýydý. LHR skoru kestirim deðeri, ROC eðrisi üzerinde 0.187 olarak alýndýðýnda %77.8 duyarlýlýk, %90.2 özgüllüðe sahipti.
TARTIÞMA: Ciddi torakoabdominal travmalý hastalarda LHR skoru mortaliteyi öngörmede yüksek duyarlýlýk ve özgülleðe sahip etkili bir parametredir.
