静脉-动脉体外膜氧合治疗的严重心源性休克患者早期容量平衡与预后分析

目的:本研究回顾性分析使用VA-ECMO治疗的严重心源性休克患者早期容量特点，及其与患者预后的关系。方法:本研究回顾南京医科大学第一附属医院急诊医学中心接受VA-ECMO治疗的患者，筛选出VA-ECMO运行≥72 h的心源性休克患者。记录患者一般情况，分析存活患者与死亡患者的前72 h容量平衡情况。根据患者前72 h容量平衡结果分组。比较两组患者性别、年龄、预后、CRRT上机率、IABP上机率、有创机械通气上机率，并计算与预后的相对危险度，比较预后是否差异有统计学意义。结果:入选77例重症心源性休克患者。共存活41例，总存活率53.2%。48~72 h容量平衡和前72 h总容量平衡在不同预后组之间差异有统计学意义。前72 h总容量负平衡组患者，与正平衡组比较，较少联合CRRT或有创机械通气。前72 h负平衡组患者存活的相对危险度为1.81，95%可信区间（1.101~2.985），有更好的存活率。但根据每24 h容量平衡情况比较生存率，差异均无统计学意义。结论:接受VA-ECMO治疗的严重心源性休克患者，前72 h总容量平衡呈负平衡的患者存活的可能性更大，且较少需要CRRT或有创机械通气。

Analysis of early volume balance and prognosis of severe cardiogenic shock patients treated with veno-arterial extracorporeal membrane oxygenation

Objective:To analyze the early volume characteristics of patients with severe cardiogenic shock treated with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and the relationship between their early volume and the prognosis.Methods:This study reviewed patients of Emergency Medical University , treated with VA-ECMO and screened the patients with severe cardiogenic shock and VA-ECMO running more than 72 h for further study. The basic condition of the patients was recorded, and the fluid balance in the first 72 h was analyzed. The patients were grouped according to their fluid balance in the first 72 h. The gender, age, survival rate, continuous renal replacement therapy (CRRT) rate, intra-aortic balloon pump (IABP) rate, and invasive mechanical ventilation rate were compared between the two groups, and the relative risk to the prognosis was calculated. The prognosis was compared between the two groups. Results:Totally 77 patients with severe cardiogenic shock were enrolled. Forty-one cases survived, with an overall survival rate of 53.2%. The volume balance at 48-72 h and the total volume balance at the first 72 h were different between the survival and dead groups. Compared with the positive balance group, patients in the negative balance group were less likely to receive CRRT or invasive mechanical ventilation during the first 72 h. Patients in the negative balance group during the first 72 h had a better survival rate, and their relative risk of survival was 1.81 (95% confidence interval: 1.101, 2.985). However, there was no significant difference in survival rate according to every 24 h fluid balance.Conclusions:Patients with severe cardiogenic shock treated with VA-ECMO who had negative total volume balance during the first 72 h are more likely to survive and less likely to require CRRT or invasive mechanical ventilation.
