Adverse Events during Inter-Hospital Transports on Extracorporeal Membrane Oxygenation.
Extracorporeal membrane oxygenation (ECMO) may be a lifesaving rescue therapy in refractory, severe respiratory, and/or circulatory failure. To provide the best cost efficiency to the population served and patient outcome, ECMO therapy should be provided by specialized high volume ECMO centers. This requires dedicated transport teams to organize and perform these complex transports. Concerning adverse events and complications during these transfers, only a minimal amount of data has been published.



To shed light on this matter, all medical transport records from transports on ECMO between January 2010 and June 2016 were analyzed. The data was classified in constituent groups and categorized to risk groups.



During the study period, 536 transports on ECMO were performed. The transport records could be identified in 514 of these cases (95.9%). In 163 (31.7%) transports 206 adverse events occurred. In 34 transports two or more adverse events passed on the same trip. No deaths occurred during transport. Sixty-five percent (134) of the complications were Patient related; the most prominent was loss of tidal volume with or without fluid flooding of the lung (n = 57, 43%). Lack of control of equipment was the most common Staff related flaw. Causes due to Equipment/technical (n = 30) could be traced to 14.6% of the events. Vehicle/transportation related complications were reported from 26 transfers, a sub-group in which 50% of the reports concerned malfunction of Ambulance utility/electrical, or Wrong ambulance size at hospital or airport.



If transporting on ECMO high-risk or sudden threat-of-life situations are inevitable and have to be dealt with immediately, sometimes within seconds. A well-trained staff and an experienced high-volume organization are recommended. Key words: extra corporeal membrane oxygenation; ECMO, transport; adverse event; complication.
