2.4 causes of death
The mortality rate was 47.83% (11/23), six neonates were weaned
successfully but died finally. Among the six patients, 5 had residual
anatomical problems, even the heart function recovered during ECMO, but
follow-up wasn’t sustainable. Three cases involved GI bleeding with
unstable circulatory function. Two cases failed to undergo further
correction for renal failure, medical cost and heart failure reasons, no
further interventions were provided and eventually both of them failed
to wean.
