I don't have my links since I did the research nearly 4 years ago, on a different computer.
But, basically - there was no medical reason to institute immediate clamping (not based on any research at all). It's one of those non-evidence-based approaches used to childbirth. Basically, clamping the cord quickly made the doctor's job quicker and easier, and so that's what they did. They justified it by saying that DCC caused the blood to 'thicken' (don't recall the medical term) and that it caused jaundice.
Actual research has shown that while there may be an increased level of jaundice, that jaundice hasn't translated to the dangerous levels in the research studies conducted. Moreover, in the research done on preemies and delayed cord clamping, even as little as 30 seconds of wait time translated to better outcomes for those infants in the NICU and beyond. There was a good article about this in Pediatrics, I think (done by a NICU nurse PhD).
On the anecdotal level - dd1 (clamped immediately) was jaundiced (but didn't require a bili light or anything) - dd2 was not jaundiced. Dd2 was also pinker, more alert when awake, had a better latch, and really seemed to thrive more in the first few weeks (she didn't lose any weight after birth, and immediately began to pile on the weight as well).
Our OB told us that he didn't have a problem with it, although it wasn't a common request and not hospital policy. He told me that IF there was a problem (too much blood loss by me) then he'd have to cut the cord and administer pitocin, but otherwise he didn't have any concerns, and likewise for our Ped.
You would want to make sure your HCP knows not to give you pitocin to manage your placental delivery (many hospitals/HCPs do this as policy unless otherwise directed).
Dd2's cord stopped pulsing after 4 minutes or so and the OB clamped her cord at that point.
Absolutely - continue your research - and consider it. I would do it with any other children we had.
(One caution - make sure that you clarify with your HCP that you want to delay CLAMPING and cutting, until the cord has ceased pulsing. I've heard stories about OBs clamping the cord and then waiting five minutes to cut it.
ETA: I brought all the scientific studies I could find, to my appointment with the OB when we talked about this. I actually met with the nurse practitioner at that appointment, she passed the papers to him and he had reviewed them prior to our appointment. I didn't bring the 'touchy-feely' articles that didn't include peer-reviewed journal publications because I wanted him to take the discussion seriously.
