Hello!

Could anybody share with me your protocol of umbilical blood sampling in delivery room, if you do it routinely? I wonder what do you check – lactate, pH or any other, in arterial or venous blood. What is your interpretation? What part of umbilical cord do you use? Is it important – the time after cutting the cord?

We want to improve this procedure in our clinic.

Thank you very much.

I have read this article and it answers all your queries

Thank you very much. Good article.

In our delivery unit, umbilical blood sampling is performed in all infants (almost). The idea is to keep up a good routine for sampling, so it is performed when it is really wanted...

I am not sure this is good strategy, one could really argue that it is "over-sampling".

We take both venous and arterial blood for analysis.

We attempt to sample the umbilical vessels from every delivery (which of course is not always possible). Double clamped segments of cords are placed on ice immediately and samples taken and analyzed within 1 hour of the delivery. Samples are taken from both the artery and the vein. Analysis is done for PO2, PCO2, ph, HCO3(st), BD/BE, and more and more we are also including lactate.
