Patient Question: Disease: Pain in hand from dialysis Description: The injection is near the hand is an artery. Now there is pain with light pressure. There was a swelling after pulling out the needle once. Then it became painful. I couldn’t see any blood leakage, and then I changed the place where I got the needle, and the top point, a large area of blood leakage. Help wanted: What should I do? What should I pay attention to? Thank you! Zhang Yixiang replied: After the needle is removed, the pressure point should include the eye of the needle, and then slightly pressed together in the direction of the tip of the needle, so as to really press on the point of entering the blood vessels, so as not to appear a large area of bruising. The bruise appears within 24 hours of cold compresses, dissipation time will take a few days. Do not play fixed point needles, ask the nurse to play more needle eyes, preferably into a line. Do not believe in the so-called buttonhole style of hitting that is currently wrongly popular. That is foreign for patients who dialyze and give their own injections at home, and requires a blunt needle to reduce damage. The distance between the two needle eyes in the photo is very long and wasteful and will shorten the life of the vessel.
