blood - platelettes + plasma + donating

Postby narrowstaircase » Sun Nov 05, 2006 1:28 am

hi, i have an interesting question.

i gave blood for the first time a couple of months ago and i was pumped to be helping out. the nurse did everything then a few minutes into the session my blood stopped flowing out of my arm. a few nurses came to check it out and they were fiddling around with the needle alot :evil: i had heaps of water during the day so that wasn't the problem. they couldn't fix it so i just left.

they normally take 500mL here in australia but i only managed to donate just over 100mL. i told my dad and sis and my sister said the exact same thing happened to her when she donated blood.

i thought this could have something to do with platelette count in my blood but then i thought no way.

a few weeks after the donation i got a letter from the blood bank asking if i would consider donating my plasma and platelettes and they just pump the red blood cells back into my arm :shock:

so i was wondering if anyone has seen/heard of this happening before? could platelette count be affecting blood flow through the needle to that degree? thanks if you take the time to read and reply!

Ouch for the needle fiddling. Not fun.

Clotting should not happen in an IV line considering they are completely under vacuum, so no O2 to clot the blood. That would be dangerous if this was not the case. So your platelet levels should not be a problem. But if they tested for it and it was high, and with my french experience I am not surprised they asked you to donate platelets. Because in fact relatively few people do it. It is ong, and with the blood cooling down during the centrifugation, some people simply pass out during the proces. Plus the anticogulants added have sometimes some disagreable secondary effects (not dangerous, but nobody likes to have full body pain and needles in the worst case...).

thanks for the reply canalon

that does not sound fun at all!
i wonder why the blood stopped flowing then...
what do you mean by "with your french experience" you are not surprised they asked me to donate platelets?

My experience is limited to France where there is a permanent lack of platelet donors for the reasons I was giving, I don't know how it is in other countries.

This said, I was listing some of the secondary effects, and except for the slight cooling effect I didn't have any trouble while giving platelets. My list is the same thing as the known side effects of drugs, usually frightening, but (lucky me) never experienced :)

And I really have no Idea why your blood stoppped flowing. Were you using your muscle? I was always given a ball to squeeze to increase the blood flow when donating.
