Was given the link to this nifty blog and videos:
So I watched it today at work no less, below are some notes from the video
(As my coworker says, they clamp it early to make the baby pull his own weight because they have been freeloading for 9 months… I love my job sometimes)
Iatrogenic is from Iatros in Greece http://en.wikipedia.org/wiki/File:Iatros.jpg
Mammals leave the umbilical cord alone and eventually the placenta/cord is eaten
Easmus Darwin advocated for delayed cord clamping
“Another thing very injurious to the child, is the tying and cutting of the navel string too soon; which should always be left till the child has not only repeatedly breathed but till all pulsation in the cord ceases.
As otherwise the child is much weaker than it ought to be, a portion of the blood being left in the placenta, which ought to have been in the child.”
Any physiological or clinical impact?
Immediate clamping causes lower blood volume. Delayed clamping causes higher blood volume, about 25% more blood in infants with delayed clamping.
At 4 days there is a 20-30% difference in blood volume
Greater then 50% increase in red blood cell volume
50% of the blood infusion from the cord is within 1 minute, the rest is in 2-5 minutes
The blood volume with the baby at the mom’s stomach or lower is the same
The umbilical artery stops pumping around 45 seconds
Bilirubin levels are under 15mg/dl in 20% of babies with delayed clamping vs 0% with immediate clamping.
A study showed that only 2% of babies with delayed cord clamping had iron deficiencies, whereas 8% with immediate clamping had an iron deficiency.
Iron amounts were higher in delayed cord clamping babies vs immediate.
Sepsis and IVH (Intraventricular hemorrhage) were both greatly lowered in premature babies who had delayed cord clamping.
Iron is essential for forming myelin.
