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.
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.
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%.
LHR score is an effective parameter with high sensitivity and specificity in predicting mortality in patients with severe thoracoabdominal trauma.
大量创伤相关死亡发生在伤后 1 小时内；因此，快速诊断和充分复苏对于预防创伤患者死亡至关重要。本研究旨在评估乳酸-红细胞压积比（LHR）评分在预测严重胸腹创伤患者死亡率中的作用。
本回顾性横断面研究纳入了 2016 年 1 月 1 日至 2019 年 12 月 31 日期间因多发伤就诊于急诊的患者。我们测量了纳入研究的严重胸腹创伤患者的血气分析值和 LHR 评分，并研究了 LHR 评分预测死亡率的有效性。
本研究纳入了 106 例严重胸腹创伤患者。患者的 30 天死亡率为 42.5%（n=45）。考虑到 30 天死亡率，死亡患者和存活患者的初始红细胞压积、乳酸、碱缺失和 LHR 评分存在统计学差异。当 LHR 评分的截断值为 0.187 时，ROC 曲线的敏感性为 77.8%，特异性为 90.2%。
LHR 评分是预测严重胸腹创伤患者死亡率的一种有效参数，具有较高的敏感性和特异性。
