摘要:

目的 探讨在脓毒症休克患者早期液体复苏过程中,联合动态监测舌下微循环灌注血管比例变化率(ΔPPV)与呼吸频率-氧合-心率(ROX-HR)指数对28 d预后的预测价值。方法 回顾性分析150例采用早期液体复苏治疗的脓毒症休克患者临床资料,依据治疗后28 d不同结局分为生存组(103例)及死亡组(47例),比较2组患者基线资料,6、24、72 h时ΔPPV及入院2 h内最低ROX-HR指数。采用Logistic回归模型分析影响脓毒症28 d死亡的独立预测因素。采用受试者工作特征(ROC)曲线评价ΔPPV及ROX-HR指数等指标对脓毒症患者28 d预后的预测价值。结果 死亡组急性生理与慢性健康评分Ⅱ(APACHEⅡ)评分、序贯器官衰竭评估(SOFA)评分、乳酸、白细胞介素(IL)-6、IL-10均高于生存组(P<0.05);格拉斯哥昏迷评分(GCS)评分、ROX-HR指数、6 hΔPPV、24 hΔPPV、72 hΔPPV均低于生存组(P<0.05)。死亡组前72 h去甲肾上腺素最大剂量高于生存组,使用时间更长,真菌感染比例亦高于生存组(P<0.05)。多因素Logistic回归分析显示,SOFA评分、乳酸升高,ROX-HR指数、72 hΔPPV降低均是脓毒症休克患者治疗28 d预后不良的危险因素(P<0.05);SOFA评分、乳酸、ROX-HR指数、72 hΔPPV预测脓毒症休克患者预后的曲线下面积(AUC)分别为0.806(95%CI:0.734~0.866)、0.757(95%CI:0.681~0.823)、0.885(95%CI:0.823~0.932)、0.890(95%CI:.0.828~0.935),敏感度分别为97.87%、87.23%、95.74%、85.11%,特异度分别为59.22%、55.34%、76.70%、80.58%;四者联合预测模型的AUC为0.989(95%CI:0.956~0.999),敏感度为91.49%,特异度为98.06%。结论 动态监测ΔPPV、ROX-HR指数联合SOFA评分、乳酸对脓毒症休克早期预后具有较高的预测价值。

Abstract:

Objective To investigate the predictive value of combining dynamic monitoring of the change rate of sublingual microcirculation perfusion vessel proportion (ΔPPV) and the respiratory rate-oxygenation-heart rate (ROX-HR) index for 28-day prognosis in patients with septic shock during early fluid resuscitation. Methods A retrospective analysis was conducted on clinical data from 150 patients with septic shock who received early fluid resuscitation in our hospital from August 2020 to September 2024. According to the 28-day outcome after treatment, patients were divided into the survival group (n=103) and the death group (n=47). Baseline data, ΔPPV at 6 h, 24 h and 72 h, and the lowest ROX-HR index within 2 h after admission were compared between the two groups. Logistic regression model was used to identify the independent predictive factors influencing 28-day mortality of sepsis. The receiver operating characteristic (ROC) curves were used to evaluate the predictive value of ΔPPV and the ROX-HR index for the 28-day prognosis of patients with sepsis. Results Acute physiology and chronic health (APACHE) Ⅱ score, sequential organ failure assessment (SOFA) score, lactate, IL-6 and IL-10 were significantly higher in the death group than those in the survival group (P<0.05), whereas Glasgow coma scale (GCS), ROX-HR index, 6 hΔPPV, 24 hΔPPV and 72 hΔPPV were significantly lower (P<0.05). The maximum dose of norepinephrine in the first 72 h was higher, the duration of usage time was longer and the proportion of fungal infection was also higher in the death group than those in the survival group (P<0.05). Multivariate Logistic regression analysis showed that increased SOFA score and lactate, decreased ROX-HR index and ΔPPV at 72 h were risk factors for poor prognosis in patients with septic shock after 28 days of treatment (P<0.05). Area under the curves (AUCs) of SOFA score, lactate, ROX-HR index and 72 hΔPPV for predicting prognosis were 0.806 (95%CI: 0.734-0.866), 0.757 (95%CI: 0.681-0.823), 0.885 (95%CI: 0.823-0.932) and 0.890 (95%CI: 0.828-0.935), with sensitivities of 97.87%, 87.23%, 95.74% and 85.11%, and specificities of 59.22%, 55.34%, 76.70% and 80.58%, respectively. The combined model (SOFA score+lactate+ROX-HR index+72 hΔPPV) achieved an AUC of 0.989 (95%CI: 0.956-0.999), with a sensitivity of 91.49% and a specificity of 98.06%. Conclusion Dynamic monitoring of ΔPPV, ROX-HR index combined with SOFA score and lactate shows superior predictive value for the early prognosis in septic shock.
