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.

What happens if phlebotomist could't find a vein?

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.

Can you tell me how to cope with a vein disease if you can't have surgery?

Can you tell me how to cope with a vein disease if you can't have surgery?

Medical options: Varicose veins are due to leaking valves in the saphenous vein system. There is a strong hereditary component. There are many potential home remedies such as horse chestnut, witch hazel and certain kinds of berries but none of these work well. If you have varicose or spider veins, then you should see a vein specialist for a venous evaluation including a venous ultrasound. Support hose may help.

Why are my veins sometimes very dark so I can see most of them? They don't stick up they justare darker and more eaasily seen

Dark veins: Firstly veins carry deoxygenated blood so they are naturally darker. Secondly if they are closer to the skin like most are and you have light skin they will be more obvious.

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?

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?

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.

I'm noticing very green veins all over my body much more noticeable than usual. Is this a problem? It doesn't hurt it's just physical appearance.

I'm noticing very green veins all over my body much more noticeable than usual. Is this a problem? It doesn't hurt it's just physical appearance.

Green Veins, Problem: It is possible that it could be a problem. The main concern is that you could be developing varicose veins, which can be a medical problem if they progress. Varicose veins most commonly form on the legs & tend to bulge out. If the veins have a more normal appearance & are throughout your body, then it may be that you are well hydrated & have light complexion & then there is nothing to worry about.

Why doesn't atherosclerosis affect veins?

Why doesn't atherosclerosis affect veins?

Low pressure: We don't know everything about how atherosclerosis works, but we do know that there has to be a certain stretch on the wall for it to get going. Venous pressure is of course much lower than arterial pressure. In the pulmonary arteries, atherosclerosis occurs when, and only when, pulmonary arterial blood pressure approaches sytemic arterial pressure.

Why does a vein visibly move?

Why does a vein visibly move?

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.

How to know if you cut a vein?

How to know if you cut a vein?

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.
