The benefits of normothermic regional perfusion (NRP) in posttransplant outcomes after controlled donation after the determination of death by circulatory criteria (cDCD) has been shown in different international adult experiences. However, there is no information on the use of NRP in pediatric cDCD donors.
This is a multicenter, retrospective, observational cohort study describing the pediatric (<18 y) cDCD procedures performed in Spain, using either abdominal NRP or thoracoabdominal NRP and the outcomes of recipients of the obtained organs.
Thirteen pediatric cDCD donors (age range, 2-17 y) subject to abdominal NRP or thoracoabdominal NRP were included. A total of 46 grafts (24 kidneys, 11 livers, 8 lungs, 2 hearts, and 1 pancreas) were finally transplanted (3.5 grafts per donor). The mean functional warm ischemic time was 15 min (SD 6 min)' and the median duration of NRP was 87 min (interquartile range, 69-101 min). One-year noncensored for death kidney graft survival was 91.3%. The incidence of delayed graft function was 13%. One-year' noncensored-for-death liver graft survival was 90.9%. All lung and pancreas recipients had an excellent evolution. One heart recipient died due to a septic shock.
This is the largest experience of pediatric cDCD using NRP as graft preservation method. Although our study has several limitations, such as its retrospective nature and the small sample size, its reveals that NRP may increase the utilization of cDCD pediatric organs and offer optimal recipients' outcomes.
在不同的国际成人研究中已表明,常温局部灌注(NRP)对循环标准判定死亡后进行的可控捐赠后移植结局有益。然而,关于NRP在小儿循环标准判定死亡捐赠者中的应用尚无相关信息。
这是一项多中心、回顾性、观察性队列研究,描述了在西班牙进行的小儿(<18岁)循环标准判定死亡捐赠程序,采用腹部NRP或胸腹联合NRP以及所获器官受者的结局。
纳入了13例接受腹部NRP或胸腹联合NRP的小儿循环标准判定死亡捐赠者(年龄范围2 - 17岁)。最终共移植了46个移植物(24个肾脏、11个肝脏、8个肺、2个心脏和1个胰腺)(每位捐赠者3.5个移植物)。平均功能性热缺血时间为15分钟(标准差6分钟),NRP的中位持续时间为87分钟(四分位间距,69 - 101分钟)。1年非死亡删失的肾移植存活率为91.3%。移植肾功能延迟发生率为13%。1年非死亡删失的肝移植存活率为90.9%。所有肺和胰腺受者情况良好。1例心脏受者死于感染性休克。
这是使用NRP作为移植物保存方法的小儿循环标准判定死亡捐赠的最大规模研究。尽管我们的研究有一些局限性,如回顾性研究性质和样本量小,但研究表明NRP可能提高循环标准判定死亡小儿器官的利用率,并为受者提供最佳结局。
