Napanuoran katkaisu ja veren virtaus

No nyt! Tätä tietoa olen etsinyt ja kaivannut. Tässä siis tutkittua tietoa niille, jotka epäilevät sitä saako vauva istukasta hänelle kuuluvat veret vaikka on äidin mahan päällä, eikä ns. kohdun alapuolella missään kärryllä... 

Suomi synnyttää -foorumilla (tark. synnytysalan ihmisille) Facebookissa Päivi Laukkanen jakoi pätkän:

Planning on immediate skin to skin, with baby up on maternal abdomen or higher? A delay in cord clamping for at least 5 minutes is required for the baby to receive a full placental transfusion.

This new clinical advice is advocated by Mercer & Erickson-Owens in their 2012 article Rethinking Placental Transfusion and Cord Clamping Issues (1), based on Erickson-Owens original research (2).

"...placing an infant skin-to-skin on the maternal abdomen slows the rate of the placental transfusion. By measuring the amount of blood left behind in the placenta, after infants are placed skin-to-skin, a 2-minute delay in cord clamping results in only a partial placental transfusion....a 2-minute delay results in an average of 25 mL/kg of whole blood left behind in the placenta compared with a 5-minute delay that leaves only an average of 11 mL/kg. A 5-minute delay in cord clamping allows the infant who is skin-to-skin to receive a full placental transfusion."
