Hematoma After Venipuncture
During venipuncture yesterday, the needle went through the arm vein. Now the ulnar nerve is paining. No visible hematoma. Is it internal bleeding?
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. ...Read more
Bad blood draw yesterday (venipuncture/8vials).Immediately:red/blue, v.swollen&painful. Now:flat, hard lump, bruise. Do ruptured veins heal? Just a leak?
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. ...Read more
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. ...Read more
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. ...Read more
Swelling/infection: During a mastectomy (removal of a breast due to cancer), a lymph node is removed from the armpit on the mastectomy side to be sure the cancer hasn't spread. In the past, removing 20+ nodes was common! Because the lymph nodes in the armpit fight infection, it wasn't uncommon for women to develop infections/swelling in that arm. So procedures, including blood draws, are limited to reduce infection. ...Read more
It depends: When you draw blood from the superficial veins of the arms you need them to be engorged so it' easier to locate and get the blood. That's the reason of the tourniquet. For the bigger veins, also called central veins (femoral, jugular, subclavian) the tourniquet is not necessary. ...Read more

What is more accurate-venipuncture or fingerstick when it comes to a CBC and will your counts be higher or lower.?
Venipuncture: Dr. Landron-garcia is right. Venipuncture is always considered to be more accurate. Finger sticks can be accurate if the stick bleeds freely but if the finger has to be squeezed to get enough blood, the results will be higher because the blood becomes more concentrated from the squeezing. ...Read more

The size of the vein: As dr. Placik said, venipuncture is for collecting blood through a needle from blood vessels that are big enough to see and/or feel. Capillary puncture would be used for collecting blood from vessels that are too small to see individually. This is usually done with a very small cut and a micro pipette or a piece of filter paper. ...Read more
