目的

构建列线图预测模型对高原地区重症机械通气患者脱机失败进行预测。

方法

选择2023 年1 月1 日至12 月31 日西藏自治区人民医院ICU 收治的需要有创机械通气的患者255 例。根据目前临床上实施的机械通气及脱机操作对患者进行常规治疗,并依据是否脱机成功,将患者分为脱机成功组(184 例)和脱机失败组(71 例)。收集2 组患者的人口学特征、合并症、生命体征、器官功能等临床指标,并进行单因素比较分析,然后将差异有统计学意义的指标纳入多因素logistic 回归分析,确立脱机失败的独立危险因素。应用列线图,建立脱机失败的预测模型。

结果

脱机失败组患者ICU 住院时间、住院费用、28 d 病死率均显著高于脱机成功组,差异有统计学意义(均P<0.005)。通过多因素logistic 回归分析显示,脱机前潮气量(Vt)(P<0.001,95%CI:0.979 ~0.992),呼吸频率(RR)(P=0.006,95%CI:1.034 ~1.218),24 h 液体平衡量(P=0.033,95%CI:1.000 ~1.001)是高原重症患者脱机失败的独立危险因素。构建预测模型受试者工作特征曲线(ROC)的曲线下面积(AUC)为0.883(95%CI:0.841 ~0.925)。

结论

高原地区重症机械通气患者脱机前Vt,RR 以及24 h 液体平衡水平显著影响脱机失败发生率。本研究基于这3 项因素构建的脱机预测模型具有良好的预测价值。

Objective

To develop a nomogram prediction model for weaning failure in mechanically ventilated critical ill patients in plateau areas.

Methods

A total of 255 patients requiring invasive mechanical ventilation admitted to the ICU of the People's Hospital of Xizang Autonomous Region between January 1 and December 31,2023,were enrolled.Based on weaning outcomes,patients were divided into a successful weaning group (184 cases) and a failed weaning group (71 cases).Demographic characteristics,comorbidities,vital signs,and organ function parameters were collected and compared between the two groups.Statistically significant variables in univariate analysis were incorporated into multivariate logistic regression to identify independent risk factors for weaning failure.And a nomogram prediction model for weaning failure was established.

Results

Compared with the successful weaning group,the failed weaning group had significantly longer ICU stays,higher hospitalization costs,and increased 28-day mortality (all P<0.001).The multivariate regression analysis identified three independent risk factors for weaning failure:tidal volume (Vt) before weaning (P<0.001,95%CI:0.979-0.992),respiratory rate (RR) before weaning(P=0.006,95%CI:1.034-1.218),and fluid balance in 24 hours before weaning (P=0.033,95%CI:1.000-1.001).The area under the ROC curve of the prediction model was 0.883 (95%CI:0.841-0.925).

Conclusions

Vt,RR,and 24-hour fluid balance levels before weaning significantly influence the incidence of weaning failure in mechanically ventilated critically ill patients in plateau areas.The nomogram prediction model developed for weaning failure in this study based on these three parameters,demonstrates a good predictive value.
