血浆胶体渗透压在早期创伤失血性休克合并ARDS中的诊断和预后价值

Clinical value of early serum colloid osmotic pressure of ARDS secondary to hemorrhagic shock

目的:探讨血浆胶体渗透压(COP)在创伤失血性休克合并ARDS患者中的早期变化以及对诊断及预后的预测价值。方法:回顾性选取2017年3月—2021年3月期间我院收治的216例创伤患者,其中无休克患者70例(A组),创伤失血性休克合并ARDS 67例(B组),未发生ARDS 79例(C组),收集入院时以及入院后24 h、48 h和72 h的白蛋白(ALB)、纤维蛋白原(FIB)水平,计算COP水平。并采用受试者工作特征(ROC)曲线进行创伤失血性休克并发ARDS诊断及预后效能评价。结果:B、C 2组COP水平在72 h中逐渐下降,B组较C组下降显著,A组变化不明显。入院时B组的ALB、FIB以及COP均显著低于A、C组。ROC曲线分析表明,入院时诊断创伤失血性休克并发ARDS的最大曲线下面积(AUC)为0.746(95%CI:0.665~0.828)(COP);预测死亡的最大AUC为0.842(95%CI:0.725,0.960)(COP)。结论:COP在创伤失血性休克合并ARDS的患者中显著下降,且可以作为创伤失血性休克并发ARDS的诊断及评估预后不良的评价指标。

Objective: To discuss the changes of serum colloid osmotic pressure(COP) in ARDS secondary to hemorrhagic shock, and evaluate the clinical value in diagnosis and mortality predication of ARDS. Methods: 216 cases of severely traumatic hemorrhage were divided into non-shock group(70 cases, A group), ARDS secondary to shock group(67 cases, B group) and non-ARDS secondary to shock group(79 cases, C group). Data of ALB, FIB and COP at admission and the 24, 48, 72 hours after admission were collected. Receiver operating characteristic(ROC) curve was used to evaluate the performance of these indexes in cases of hemorrhagic shock with ARDS diagnosis and mortality prediction. Results: The levels of COP decreased significantly in group B and group C, and did not change obviously in group A at all time points. The levels of ALB, FIB and COP were significantly lower in group B compared with group A and group C. There were 45 patients died in group B plus group C, whose ALB, FIB and COP levels at admission were significantly lower than those of the survival ones. ROC curves suggested that the best predictive AUC of the early diagnosis in cases of hemorrhagic shock with ARDS at admission were 0.746(95%CI: 0.665-0.828)(COP). Meanwhile the best predictive AUC of mortality at admission was 0.842(95%CI: 0.725-0.960)(COP). Conclusion: It is possible that COP should be as significant diagnostic indicators for ARDS secondary to severely traumatic hemorrhage and as predictive markers for poor prognosis of cases with ARDS.
