Question 1

every time i get a blood test they can't find a vein. what causes this?

Accepted Answer

Dehydration: Dear Myra,

If you are dehydrated it may be difficult for someone to find a vein.  Some people also have very small veins as their anatomy.  Please drink plenty of water prior to having a blood draw.

Question 2

every time i go to get blood drawn the nurse can't find a vein. why?

Accepted Answer

Your veins run: deep in your  arm. They are not superficial. Therefore one must dig to find veins.

Question 3

what happens if you can't find the veins of a patient in an emergency-room setting?

Accepted Answer

Other options: Getting IV access is vital in an acute scenario. At times, antecubrtal areas are not helpful. At these times, the  top of the foot, inguial area or subclavian access may be needed. These are harder to access but are ususally successful. Inguial sticks access the femoral veins and must only be done by experienced hands, same for a subclavian or central-line approach.

Question 4

what happens if phlebotomist could't find a vein?

Accepted Answer

Have MD draw blood.: There are many options for drawing blood if it cannot be taken from the routine areas.  This occurs periodically with children, with adults with no veins and in a trauma setting. The options would be to hydrate and warm the person and re-evaluate. Next try using a vein lite or syris head light to find the veins followed by ultrasound identification of the subclavian vein or a femoral vein stick.

Question 5

the veins on my wrists aren't visible. why?

Accepted Answer

OK: Either they are small or you have increased subcutaneous fat.

Question 6

i had the vnus closure procedure done 1 wk ago. my vein still looks vericosed. does this mean it didn't work? when can i expect to see results?

Accepted Answer

Depends: The vnus closure uses rf energy to seal varicose veins where the catheter was placed.  During the seal process, the vein is thrombosed.  The sealed vein will, over time be absorbed by the body..Until that time, the vein maybe visible or palpable.  Absorption should be completed by the body over 4-8 months.  Often times patients require added sclerotherapy for associated varicose veins post vnus.

Question 7

my blood is extremely dark almost black and thick. 2 days ago it was bright n normal. hard to locate vein with iv or blood isn't drawing correctly to locate vein easily?

Accepted Answer

: Keeping the tourniquet for longer than a minute or so can make the blood look darker. If the results of blood tests are okay, do not be concerned about the color of blood, especially if it was red earlier.
For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, drink enough water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs.

Question 8

why doesn't atherosclerosis affect veins?

Accepted Answer

Atherosclerosis: There is a venosclerosis but it is uncommon. Atherosclerosis forms in part because of the pressure dynamics in the muscular walled arteries and arterioles. The pressure dynamic is much lower in veins.

Question 9

why does a vein visibly move?

Accepted Answer

connective tissue: Veins (in the hands, especially) tend to be fixed only at branching points.  Tough connective tissue holding them in one place is only present in certain anatomical locations.  In the rest of the hand and arms, the veins may "roll" or move through the tissue plane they are in.  This is totally normal.

Question 10

how to know if you cut a vein?

Accepted Answer

You bleed: Although some bleeding is usual after a traumatic puncture or laceration, the way to identify if you damaged a big vessel is by the amount of bleeding and the difficulty in stopping the bleeding.  If you damaged a vein you would see that blood flow is continuous while if you damaged an artery the blood flow would be pulsatile.
