Re: [ozmidwifery] cord blood gases

Sorry Been to London to see Lion King with the kids! It was Fab! Perhaps we should all start to keep stats of babes in good condition with poor gases. I do not work in that environment any more, but it is the only way to prove what many of us are saying, Here are some refs. Some refs from hospital policies (advocating cord sampling) which I have copies of are from 1984 interestingly! Apologies for the style of refs. Admin did them for me.

Sometimes older research is used when there are multiple research papers over a long period of time, like in newborn jaundice. "What you could do Mary is ask them what research they are using to back up the use of cord gases and see how long ago that was produced". I have never collected a cord sample for "gasses" as I only practice in homebirth.  I guess we could look up the protocols for taking the cord blood and see what the references.  Could someone who works in a hospital do that for us please?
