| Research Abstract |
Because previous studies aimed at developing an artificial placenta have had limited success, we hypothesized that the introduction of a high-performance membranous oxygenator to a pumpless artificial placenta could prolong the survival time of premature lambs. Immediately after the delivery of the fetuses, the umbilical vessels were cannulated and connected to the pumpless artificial placenta. Both the fetuses and the circuit were submerged in a warm saline bath. Five fetuses survived for 18. 2 ± 3. 2 (mean ± SEM)hours after attachment to the artificial placenta, which maintained the fetal circulation. We prolonged the survival of fetal lambs using a high-performance membranous oxygenator with a small priming volume.
