Role of glucose/potassium ratio and shock index in predicting mortality in patients with isolated thoracoabdominal blunt trauma

BACKGROUND: The aim of this study, investigate the prognostic value of shock index (SI), which has been accepted for a long time, and glucose-potassium ratio (GPR), which has limited data in patients with trauma and those with isolated blunt thoracoabdominal trauma.
METHODS: This retrospective observational study was conducted at the tertiary reference hospital. Consecutive patients aged 18 years and older treated for blunt thoracoabdominal trauma in the emergency department between August 2020 and February 2022 were included in the study. The ability of GPRs obtained from arterial blood gases and SI levels on admission to predict mortality and indication for surgery was evaluated by calculating areas under receiver operating characteristic curves Area under the curve (AUCs).
RESULTS: A total of 102 patients, of which 91 in the survivor group and 11 in the non-survivor group, were analyzed. The AUCs for estimating mortality with GPR and SI were 0.854 (95% confidence interval [CI], 0.742–0.967) and 0.809 (95%, 0.666–0.952), respectively. The AUCs of GPR and SI to estimate the indication for surgery were 0.761 (95% CI, 0.657–0.864) and 0.582 (95% CI, 0.416–0.747), respectively.
CONCLUSION: This study reported the efficacy of SI and GPR in predicting surgical indication and mortality in patients with isolated blunt thoracoabdominal trauma and the superior predictive role of GPR over SI.

Glukoz/potasyum oraný ve þok indeksi’nin izole künt torakoabdominal travmalý hastalarda mortalite tahmin etmedeki rolü

AMAÇ: Bu çalýþmanýn amacý, uzun süredir kabul gören þok indeksi ve verileri sýnýrlý olan glukoz/potasyum oranýnýn izole künt torakoabdominal travmalý hastalarda prognostik deðerini araþtýrmaktýr.
GEREÇ VE YÖNTEM: Bu geriye dönük gözlemsel çalýþma üçüncü basamak bir referans hastanede yürütüldü. Aðustos 2020 ile Þubat 2022 arasýnda acil serviste künt torakoabdominal travma nedeniyle tedavi edilen 18 yaþ ve üstü ardýþýk hastalar alýndý. Giriþte arteriyel kan gazlarýndan elde edilen glukoz/potasyum oranlarý ve þok indeksi düzeylerinin mortalite ve cerrahi endikasyonu öngörme yeteneði, ROC eðrileri altýnda kalan alanlar hesaplanarak deðerlendirildi.
BULGULAR: Sað kalan grubunda 91 ve mortalite grubunda 11 olmak üzere toplam 102 hasta analiz edildi. Glikoz/potasyum oraný ve þok indeksi ile mortaliteyi tahmin etmek için ROC eðrileri altýnda kalan alanlar sýrasýyla 0.854 (%95 GA, 0.742–0.967) ve 0.809 (%95, 0.666–0.952) idi. Ameliyat endikasyonunu tahmin etmek için glukoz/potasyum oraný ve þok indeksinin ROC eðrileri altýnda kalan alanlarý sýrasýyla 0.761 (%95 GA, 0.657–0.864) ve 0.582 (%95 GA, 0.416–0.747) idi.
TARTIÞMA: Bu çalýþma, izole künt torakoabdominal travmalý hastalarda cerrahi endikasyonu ve mortalityi öngörmede þok indeksi ve glikoz/potasyum oranýnýn etkinliðini ve glikoz/potasyum oranýnýn þok indeksine göre daha üstün olduðunu bildirmiþtir.
