| Research Abstract |
We have developed an extrauterine fetal incubation system using V-A ECMO via cervical vessels for the treatment of a fetus with a congenital diaphragmatic hernia. The purpose of this study was to examine the feasibility of extrauterine incubation of an isolated premature fetal lamb in the artificial placenta.
The fetuses were(125〜140 days gestational age) were incubated in an isolated artificial amniotic fluid with VA ECMO.
The fetuses were then removed from the incubator and ventilated through a tracheostomy.
The circulation and respiratory state of fetuses during the incubation to ventilation were evaluated by blood gas analysis and colour Doppler ultrasonographic examinations revealed stablecondition undepended on hemodynaniic change of the ductus arteriosus and foramen ovale.
These resuls may indicate that the cervical VA ECMO can effectively support extrauterine intubation of isolated premature fetuses.
