Stopped flow during blood donation?

Question

During a seemingly routine blood donation, the blood flow was very slow and stopped after about 30 minutes. The nurse tried moving the needle around, squeezing the arm, and moving the donor, but nothing more would come out. When the needle was taken out, the blood was spurting out of the arm just fine. The donation was stopped after only 1/2 the usual amount was retrieved.

Why wouldn't the blood go into the needle during the donation? I can think of several reasons, but I don't know if my reasons are medically sound.

Thanks for any informed opinions.

Answer 1

Sometimes the bevel of the needle comes to rest against the wall of your blood vessel - that's why the technician moved the needle slightly within the vein. Occassionally, a person can form a small clot around the needle, preventing any blood from entering it. Also, sometimes people are not well hydrated prior to donating, which may make the blood flow slower.

earlier every physique else harps on the capacity of the blood economic employer technicians (that they do no longer comprehend what they are doing, et cetera), enable me to make sparkling some factors. Blood series is unquestionably a technology and not absolutely everyone are stable donors. some are surpassed over because of the fact of evident medical motives (like they are HIV+ or another disease) mutually as some are surpassed over for purely actual motives; it is, some human beings in simple terms have not got the veins to donate. Blood for donation needs to come back out of a guy or woman at an extremely speedy value in any different case it could clot interior the tube. in the journey that your veins won't be able to sustain a minimum flow value, that should disqualify you. further, with a view to realize that flow value, they put in a length 14 GA needle. it is the main important vein needle in existence. in the journey that your veins are the type that they have hardship in simple terms drawing recurring blood tests from, then save your self the time and aggravation. don't be stunned that they are able to't get a speedy sufficient blood return and get in touch with it an afternoon. Or might you be happier if the tech stored attempting until eventually you have been black and blue? thank you to your generosity and humanity in attempting to donate. exhibit your sadness on your mom and pa for providing you with such uncooperative veins. how many veins have i in my opinion caught? a pair of quarter million. And no, i'm no longer exaggerating the two. Ralph

Probably small clot from your blood got stuck in the needle or tube to the bag. Remember to squeeze that little ball thing, especially if you're a clotter! (I'm a bleeder, I'm done in 5 to 7 minutes).

Answer 4

usualy they give you a stress ball to squize with the fist that the blood is coming out of did they do that? the squizing of the fist acts like a pump.
