ABSTRACT
Objective. Many centers are able to emergently deploy extracorporeal membrane oxygenation (ECMO) as support
in children with refractory hemodynamic instability, but may be limited in their ability to provide prolonged
circulatory support or cardiac transplantation. Such patients may require interhospital transport while on ECMO
(cardiac mobile [CM]-ECMO) for additional hemodynamic support or therapy. There are only three centers in the
United States that routinely perform CM-ECMO. Our center has a 20-year experience in carrying out such
transports. The purpose of this study was twofold: (1) to review our experience with pediatric cardiac patients
undergoing CM-ECMO and (2) identify risk factors for a composite outcome (defined as either cardiac transplan-
tation or death) among children undergoing CM-ECMO.
Design. Retrospective case series.
Setting. Cardiovascular intensive care and pediatric transport system.
Patients. Children (n = 37) from 0–18 years undergoing CM-ECMO transports (n = 38) between January 1990 and
September 2005.
Interventions. None.
Measurements and Main Results. A total of 38 CM-ECMO transports were performed for congenital heart disease
(n = 22), cardiomyopathy (n = 11), and sepsis with myocardial dysfunction (n = 4). There were 18 survivors to
hospital discharge. Twenty-two patients were transported a distance of more than 300 miles from our institution. Ten
patients were previously cannulated and on ECMO prior to transport. Thirty-five patients were transported by air
and two by ground. Six patients underwent cardiac transplantation, all of whom survived to discharge. After adjusting
for other covariates post-CM-ECMO renal support was the only variable associated with the composite outcome of
death/need for cardiac transplant (odds ratio = 13.2; 95% confidence interval, 1.60–108.90; P = 0.003). There were
two minor complications (equipment failure/dysfunction) and no major complications or deaths during transport.
Conclusions. Air and ground CM-ECMO transport of pediatric patients with refractory myocardial dysfunction is
safe and effective. In our study cohort, the need for post-CM-ECMO renal support was associated with the
composite outcome of death/need for cardiac transplant.

xtracorporeal membrane oxygenation
(ECMO) is an important support modality for
patients with refractory hemodynamic instability,
which can develop in the setting of congenital heart
disease, systemic illness, or postcardiotomy.
