That is a very interesting link. (Thanks)
I thought this part was particularly interesting:
Quote:
| The immediately clamped newborn has, in effect, been subjected to a massive hemorrhage, [12] losing up to 50% of its blood volume; however, the actual amount of blood loss varies greatly with the circumstances of the particular birth and with the speed with which the cord is clamped. At normal, spontaneous delivery, the contracting uterus may squeeze blood into the child during the second stage of labor; if the child cries before the trunk is delivered, the contraction that delivers the child may also deliver a “full” placental transfusion before the clamp can be applied. Similarly, a mother who delivers in the squatting position will usually transfuse the child fairly adequately by gravity before the clamp can be applied. A normal, spontaneous delivery (with the mother supine) followed by immediate placement of the child on the mother’s abdomen may result in considerable gravitational blood loss into the placenta if the clamp is placed during uterine diastole. Rarely, when a clamp happens to be placed during a strong uterine contraction, the child may be over-transfused with blood that would have drained back into the placenta had the clamp not been placed. In general, most newborns that breathe immediately after a normal vaginal delivery will not lose a critical amount of blood volume from early cord clamping. |
So, I guess all the doctors are not quite incorrect when they talk about the baby needing to be lower than the placenta or the blood will flow back out of the baby. Of course, it all depends on if the cord is clamped and when.
