Introduction: The organization of primary Extracorporeal membrane oxygenation (ECMO) transport is highly variable.
Methods: To present the experience of the first mobile pediatric ECMO program in Spain, we designed a prospective descriptive study of all primary neonatal and pediatric (0-16 years) ECMO transports carried out over 10 years. The main variables recorded include demographic information, patient background, clinical data, ECMO indications, adverse events, and main outcomes.
Results: 39 primary ECMO transports were carried out with a 66.7% survival to hospital discharge. The median age was 1.24 months[IQR: 0.09-96]. Cannulation was mostly peripheral venoarterial (33/39). The mean response time from the call from the sending center to the departure of the ECMO team was 4 h[2.2-8]. The median inotropic score at the time of cannulation was 70[17.2-206.5], with a median oxygenation index of 40.5[29-65]. In 10% of the cases, ECMO-CPR was performed. Adverse events occurred in 56.4%, mostly related to the means of transport (40% overall). On arrival at the ECMO center, 44% of the patients underwent interventions. The median PICU stay was 20.5 days[11-32]. 5 patients developed neurological sequels. Statistically significant differences between survivors and deceased patients were not found.
Conclusions: A good survival rate, with a low prevalence of serious adverse events, suggests a clear benefit of primary ECMO transport when conventional therapeutic measures are exhausted and the patient is too unstable to undergo conventional transport. A nationwide primary ECMO-transport program must therefore be offered to all patients regardless of their location.
