Question 1

during venipuncture yesterday, the needle went through the arm vein. now the ulnar nerve is paining. no visible hematoma. is it internal bleeding?

Accepted Answer

Possibly irritated: I don't understand how venipuncture can get to the ulnar nerve but it can certainly puncture some other nerves.  I suspect that the pain will be transient lasting no more than a week . If the problem persists beyond that or not improving, better contact your doctor  Ice the area if the pain is unbearable.

Question 2

bad blood draw yesterday (venipuncture/8vials).immediately:red/blue, v.swollen&painful.now:flat,hard lump,bruise.do ruptured veins heal?just a leak?

Accepted Answer

Hematoma: The venipuncture for blood draw leaked and caused a hematoma outside of the vein or in the vein wall or both and this will heal in most cases without any consequences. I recommend ice in the first 2 days, several times a day (15 min each time) and switch to topical heat on day 3-4 and take ibuprofen as tolerated.

Question 3

what is the angle that venipuncture is performed?

Accepted Answer

Varies: There is no set rule on the angle of entry.  For smaller veins close to the skin, the angle is more acute with the needle/catheter closer to the skin.  Deeper veins may require 45 degree angle, and larger angles make for more difficult entry as the tip may easily penetrate the back wall of the vein.

Question 4

what are the problems that can come from venipuncture?

Accepted Answer

Few: In general venipuncture is safe, problem-free, and well-tolerated.  Occasionally it may be associated with a poor sample quantity, more than expected discomfort, inability to access vein or obtain sample, hematoma, or the need to return for another sample attempt.  Infection or other vascular issues are very rare.

Question 8

Question 9

what is the normal post-op care for a venipuncture site?

Accepted Answer

Usually nothing: The site is small and holding pressure for a few minutes is all that is required. Raising the arm may help some.
Many will place a bandaid or small dressing to keep any ooze off clothes or surroundings
 a site for blood donation may be a bit larger and require longer pressure or occasionally a brief pressure dressing. Veins are low pressure.

Question 10

ideas? what are possible areas where venipuncture can be performed?

Accepted Answer

Many areas.: Venipunctures can be performed in many areas but the most common are in the veins in the hands or arms.  Sometimes, in people whose veins are difficult to fine, veins in the groins (femora's) or even the neck (jugular) can be used.
