Artificial uterus the United States. A human placenta may theoretically be transplanted inside an artificial uterus, but the passage of nutrients across this artificial uterus remains an unsolved issue. The main function of an "amniotic tank" would be to fill the function of the amniotic sac in physically protecting the embryo or fetus, optimally allowing it to move freely. It should also be able to maintain an optimal temperature. Lactated Ringer's solution can be used as a substitute for amniotic fluid. Theoretically, in case of premature removal of the fetus from the natural uterus, the natural umbilical cord could be used, kept
Umbilical cord higher rate of neonatal jaundice requiring phototherapy. Delayed clamping is not recommended as a response to cases where the newborn is not breathing well and needs resuscitation. Rather, the recommendation is instead to immediately clamp and cut the cord and perform cardiopulmonary resuscitation. The umbilical cord pulsating is not a guarantee that the baby is receiving enough oxygen. However, where possible, one should perform cardiopulmonary resuscitation with the cord still attached, to receive both benefits of oxygen from the cord and from the intervention. Some parents choose to omit cord severance entirely, a practice called "lotus birth" or umbilical nonseverance.
