- Abstract
Background: Extracorporeal life support (ECLS) for status asthmaticus (SA) is rare. Increased safety and experience may increase utilization of ECLS for SA. Methods: 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. Results: 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 pCO2 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. Conclusions: 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.
