摘要
目的探讨体外膜氧合(ECMO)支持危重患儿二级转运的临床安全性及有效性。方法回顾性队列分析。收集5家ECMO中心和中国儿科体外生命支持联盟数据库中于2019年5月至2024年5月的222例ECMO转运患儿病例资料,根据转运性质分为初级转运组和二级转运组,采用两独立样本t检验、Wilcoxon秩和检验和χ^(2)检验或Fisher确切概率法比较两组一般情况、ECMO支持原因、转运距离、转运前实验室检查结果以及预后和并发症等资料。结果222例ECMO转运患儿中男135例、女87例,年龄3.0(0.2,7.0)岁,初级转运组202例,二级转运组20例,二级转运患儿均在当地尝试撤离ECMO失败后启动二级转运。二级转运组患儿ECMO支持年龄、切开置管比例、循环支持比例、支持前乳酸水平均高于初级转运组[7.0(2.8,10.0)比3.0(0.2,6.0)岁、55.0%(11/20)比3.6%(7/202)、80.0%(16/20)比41.6%(84/202)、(10±4)比(7±6)mmol/L,Z=3.41,χ^(2)=66.31、10.99,t=2.24,均P<0.05]。二级转运组循环支持患儿转运前的血管活性药物指数、呼吸支持患儿氧合指数高于初级转运组(83±33比82±68、51.0±1.8比37.4±10.2,t=2.36、2.63,均P<0.05),两组患儿性别、转运距离、ECMO前肌酐、动脉血气碱剩余值及ECMO转流时长差异均无统计学意义(均P>0.05),两组患儿转运过程中均未发生危及生命的并发症。二级转运组有2例患儿接受心脏移植,1例接受射频消融。两组患儿总体存活率差异无统计学意义[45.0%(9/20)比55.4%(112/202),χ^(2)=1.15,P>0.05]。结论儿科ECMO二级转运过程中并未增加病死率及危及生命的并发症发生率,当地无法得到有效治疗的ECMO患儿,二级转运转至高级ECMO中心,可以获得进一步的治疗机会。
Objective To evaluate the safety and efficacy of secondary transport on extracorporeal membrane oxygenation(ECMO)for critically ill children.Methods This was a retrospective cohort study.Data from 222 pediatric patients who underwent ECMO transport from May 2019 to May 2024 at 5 ECMO centers and Chinese Database of Pediatric Extracorporeal Life Support Organization were collected.The cases were divided into primary and secondary transport groups by nature of transport.The clinical data,including demographics,ECMO indications,transport distance,pre-transport lab results,prognosis and complications were analyzed.Two independent samples t-test,Wilcoxon test,andχ^(2)test or Fisher′s exact probability method were used to compare the differences between 2 groups and evaluate the safety and efficacy of secondary transport.Results Among the 222 children transported with ECMO,there were 135 males and 87 females,with an age of 3.0(0.2,7.0)years.There were 202 cases in the primary transport group and 20 cases in the secondary transport group.All secondary transport patients had failed attempts at weaning ECMO before transfer.The patients in the secondary transport group were older,had higher rates of surgical cannulation,circulatory support,and pre-ECMO lactate levels compared to the primary transport group(7.0(2.8,10.0)vs.3.0(0.2,6.0)years old,55.0%(11/20)vs.3.6%(7/202),80.0%(16/20)vs.41.6%(84/202),(10±4)vs.(7±6)mmol/L,Z=3.41,χ^(2)=66.31,10.99,t=2.24,all P<0.05).In the secondary transport group,the vasoactive-inotropic scores of patients on circulatory support and the oxygenation index for patients requiring respiratory support were higher than those in the primary transport group(83±33 vs.82±68,51.0±1.8 vs.37.4±10.2,t=2.36,2.63,respectively;both P<0.05).There were no statistically significant differences between the 2 groups in sex,transport distance,pre-ECMO creatinine,arterial blood gas BE values,and ECMO duration(all P>0.05).No life-threatening complications occurred during the transport in either group.Two patients in the secondary transport group underwent heart transplantation,and 1 patient underwent radiofrequency ablation.The overall survival rate between the 2 groups showed no statistically significant difference(45.0%(9/20)vs.55.4%(112/202),χ^(2)=1.15,P>0.05).Conclusions Secondary ECMO transport for critically ill children don't increase mortality or life-threatening complications during transport.ECMO patients who cannot receive effective treatment locally can benefit from secondary transport to an advanced ECMO center provides further treatment opportunities.
