The University of Michigan experience with extracorporeal life support (ECL
S) in 1000 consecutive patients between 1980 and 1998 is the largest series
at one institution in the world. Among this patient population, survival t
o hospital discharge in moribund patients with respiratory failure was 88%
in 586 neonates, 70% in 132 children, and 56% in 146 adults. Survival in mo
ribund patients with cardiac failure was 48% in 105 children and 33% in 31
adults. This article describes the University of Michigan's overall ECLS pa
tient experience, the progression of ECLS from laboratory experiments to cl
inical application at the bedside, the expansion of the technology to other
centers, and current ECLS technology and outcomes. Despite the challenges
faced in clinical research in this field, our experience and that of others
has shown that ECLS saves lives of patients with acute cardiac or pulmonar
y failure in a variety of clinical settings.
