Abstract

OBJECTIVES

To estimate the organ donation potential of patients dying at a children's hospital.

DESIGN

Retrospective cohort study.

SETTING

A free-standing, 271-bed, tertiary Children's Hospital with a pediatric trauma center.

PATIENTS

Patients dying in any ICU during 2011-2012.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Among 224 deaths, 23 (10%) met neurologic criteria for death: 18 donated organs (conversion rate 78%), 47 (19%) died without prior limitation of life-sustaining therapies, and the remaining 69% had withdrawal of life-sustaining therapies. Among those dying after withdrawal of life-sustaining therapies (n = 154), the organ procurement organization was not notified prior to death in 24%, and older patients were more likely to be referred compared to those less than 1 year old. Infection, cancer, and organ dysfunction were the most frequent conditions that disqualified dying patients from suitability for donation. Just over half of children more than 1 year old were suitable for donation after withdrawal of life-sustaining therapies compared to a fifth of infants (19%). Of 45 suitable for donation, 37 (82%) died within 1 hour. None of 7 infants younger than 1 month old died within 20 minutes, compared with 46% of infants between 1 month and 1 year (n = 6) and 72% of older children. Thirty-three families (73%) did not permit donation after circulatory criteria for death whereas 12 (27%) gave permission for donation, and all 12 were actual donors (conversion rate 12/37 [32%]).

CONCLUSIONS

The number of pediatric potential candidates for donation after circulatory determination of death was significantly larger than potential candidates for donation after neurologic determination of death at our hospital, but the actual donation rate was significantly lower. Increasing acceptance of donation after circulatory determination of death could increase organ donation. Among all children having withdrawal of life-sustaining therapies, donation after circulatory determination of death potential is less for infants.

摘要

目的

评估一家儿童医院中死亡患者的器官捐献潜力。

设计

回顾性队列研究。

地点

一家拥有271张床位的独立三级儿童医院及儿科创伤中心。

患者

2011年至2012年期间在任何重症监护病房死亡的患者。

干预措施

无。

测量指标及主要结果

在224例死亡病例中,23例(10%)符合脑死亡标准:18例捐献了器官(转化率78%),47例(19%)在生前未接受过维持生命治疗限制的情况下死亡,其余69%接受了维持生命治疗的撤除。在接受维持生命治疗撤除后死亡的患者中(n = 154),24%在死亡前未通知器官获取组织,与1岁以下患者相比,年龄较大的患者更有可能被转诊。感染、癌症和器官功能障碍是导致死亡患者不适合捐献的最常见情况。与五分之一的婴儿(19%)相比,超过1岁的儿童在接受维持生命治疗撤除后超过一半适合捐献。在45例适合捐献的患者中,37例(82%)在1小时内死亡。1个月以下的7例婴儿中无1例在20分钟内死亡,相比之下,1个月至1岁的婴儿中有46%(n = 6),年龄较大的儿童中有72%。33个家庭(73%)在循环死亡标准确定后不允许捐献,而12个家庭(27%)允许捐献,且所有12个家庭均为实际捐献者(转化率12/37 [32%])。

结论

在我院,循环判定死亡后潜在的儿科捐献候选人数显著多于脑死亡判定后的潜在捐献候选人数,但实际捐献率显著较低。提高对循环判定死亡后捐献的接受度可增加器官捐献。在所有接受维持生命治疗撤除的儿童中,婴儿循环判定死亡后潜在的捐献可能性较小。
