A panel of pediatric experts met to develop recommendations on the technical requirements specific to pediatric controlled donation after planned withdrawal of life-sustaining therapies (Maastricht category III). The panel recommends following the withdrawal of life-sustaining therapies protocol usually applied in each unit, which may or may not include immediate extubation. The organ retrieval process should be halted if death does not occur within 3 h of life-support discontinuation. Circulatory arrest is defined as loss of pulsatile arterial pressure and should be followed by a 5-min no-touch observation period. Death is declared based on a list of clinical criteria assessed by two senior physicians. The no-flow time should be no longer than 30, 45, and 90 min for the liver, kidneys, and lungs, respectively. At present, the panel does not recommend pediatric heart donation after death by circulatory arrest. The mean arterial pressure cutoff that defines the start of the functional warm ischemia (FWI) phase is 45 mmHg in patients older than 5 years and/or weighing more than 20 kg. The panel recommends normothermic regional perfusion in these patients. The FWI phase should not exceed 30 and 45 min for retrieving the pancreas and liver, respectively. There is no time limit to the FWI phase for the lungs and kidneys. The panel recommends routine sharing of experience with Maastricht-III donation among all healthcare institutions involved in order to ensure optimal outcome assessment and continuous discussion on the potential difficulties, notably those related to the management of normothermic regional perfusion in small children.
一个儿科专家小组开会制定了关于计划撤回生命支持治疗后的小儿控制性捐赠的具体技术要求的建议(马斯特里赫特 III 类)。专家组建议遵循每个单位通常应用的撤生命支持治疗方案,该方案可能包括也可能不包括立即拔管。如果在停止生命支持后的 3 小时内未死亡,则应停止器官获取过程。循环停止定义为搏动性动脉压丧失,应随后进行 5 分钟的无触摸观察期。死亡是根据两名高级医生评估的一系列临床标准宣布的。无血流时间对于肝脏、肾脏和肺分别不应超过 30、45 和 90 分钟。目前,专家组不建议在心跳停止后进行小儿心脏捐赠。在年龄大于 5 岁和/或体重超过 20 公斤的患者中,定义功能热缺血(FWI)阶段开始的平均动脉压截止值为 45mmHg。专家组建议对这些患者进行全身常温区域灌注。FWI 阶段用于获取胰腺和肝脏的时间分别不应超过 30 和 45 分钟。FWI 阶段对于肺和肾脏没有时间限制。专家组建议所有参与的医疗机构常规分享马斯特里赫特 III 捐赠经验,以确保最佳结果评估和持续讨论潜在困难,特别是与小儿全身常温区域灌注管理相关的困难。
