Extracorporeal life support (ECLS) for status asthmaticus (SA) is rare. Increased safety and experience may increase utilization of ECLS for SA.
We reviewed pediatric (<18 years old) patients requiring ECLS for SA between 1998 and 2019 within the Extracorporeal Life Support Organization (ELSO) Registry and Nemours Children's Health (NCH) system. We compared patient characteristics, pre-ECLS medications, clinical data, complications, and survival to discharge between Early (1988-2008) and Late (2009-2019) eras.
From the ELSO Registry, we identified 173 children, 53 in Early and 120 in Late eras, with primary diagnosis of SA. Pre-ECLS hypercarbic respiratory failure was similar between eras (median pH 7.0 and pCO 111 mm Hg). Venovenous mode (79% vs. 82%), median ECLS time (116 vs. 99 h), time to extubation (53 vs. 62 h), and hospital survival (89% vs. 88%) also remained similar. Intubation to cannulation time significantly decreased (20 vs. 10 h, p = 0.01). ECLS without complication occurred more in the Late era (19% vs. 39%, p < 0.01), with decreased hemorrhagic (24% vs. 12%, p = 0.05) and noncannula-related mechanical (19% vs. 6%, p = 0.008) complications. Within NCH, we identified six Late era patients. Pre-ECLS medication favored intravenous beta agonists, bronchodilators, magnesium sulfate, and steroids. One patient died from neurological complications following pre-ECLS cardiac arrest.
Collective experience supports ECLS as a rescue therapy for pediatric SA. Survival to discharge remains good, and complication rates have improved. Pre-ECLS cardiac arrest may potentiate neurologic injury and impact survival. Further study is needed to evaluate causal relationships between complications and outcomes.
体外生命支持(ECLS)治疗哮喘持续状态(SA)较为少见。安全性和经验的提高可能会增加 ECLS 在 SA 中的应用。
我们对 1998 年至 2019 年期间在体外生命支持组织(ELSO)登记处和 Nemours 儿童健康(NCH)系统中接受 ECLS 治疗的小儿(<18 岁)哮喘持续状态患者进行了回顾性研究。我们比较了两个时期(早期:1988-2008 年;晚期:2009-2019 年)患者的特征、ECLS 前用药、临床数据、并发症和出院存活率。
在 ELSO 登记处,我们共确定了 173 名患儿,其中早期 53 名,晚期 120 名,主要诊断为 SA。ECLS 前高碳酸血症性呼吸衰竭在两个时期相似(中位 pH 值 7.0 和 pCO2 111mmHg)。静脉-静脉模式(79%比 82%)、中位 ECLS 时间(116 比 99h)、拔管时间(53 比 62h)和住院存活率(89%比 88%)也相似。插管到置管时间明显缩短(20 比 10h,p=0.01)。晚期 ECLS 无并发症的发生率更高(19%比 39%,p<0.01),出血性并发症(24%比 12%,p=0.05)和非插管相关机械并发症(19%比 6%,p=0.008)减少。在 NCH,我们共确定了 6 名晚期患儿。ECLS 前用药倾向于静脉内β受体激动剂、支气管扩张剂、硫酸镁和类固醇。1 名患儿在 ECLS 前心脏骤停后出现神经并发症死亡。
综合经验支持 ECLS 作为小儿 SA 的抢救治疗。出院存活率仍然较高,并发症发生率有所改善。ECLS 前心脏骤停可能会加重神经损伤并影响存活率。需要进一步研究以评估并发症与结局之间的因果关系。
