On the variation or difficult vascular puncture technique adopted


08 a OO23 (2OO4) O5-0480-01 puncture technique can be directly or indirectly affect the mood of blood donors, median cubital vein, basilic vein and cephalic vein is best described in the books puncture the vein. We usually work in almost all of these three veins with blood sampling. Work in practice have encountered several cases of variant situation. Sometimes in the hands of donors can not find this three elbow back of knee vein, we will continue to look for another vein. Now turn to practical work encountered in several abnormal blood vessels and the needle points and considerations. Example One: With the continuous improvement of living standards. Obese people in society are also a growing trend. Comparison of fat people. Vein will be covered with thick layer of fat to live. Then we fastened cuff and gently tapping the normal anatomy of cubital vein position. If you do not feel, will urge donors clenched fist, made of hand flexion and extension movements. Median cubital vein and then gently massage the palm of the normal anatomical location. With the index finger a little harder to go touch, feel cubital vein exists. If you feel, then the needle will significantly different from the superficial vein. First, tighten the skin, the needle should be chosen from the cubital fossa at the location about 5 cm under the aligned position of 45 vessels. Needle. Advanced further into the fatty layer of skin, and finally reduce the angle of the needle to the vascular smooth needle position. Although divided in three steps. However, in order to reduce the pain of blood donors, these three actions we should be consistent and rapid completion. Example: strong crowd who developed the muscles in particular. This person's blood vessels or muscles to be strong to cover either in the epidermis. Muscles are often hidden out of the larger blood vessels. So hard to find in the elbow cubital fossa vein, basilic vein or cephalic vein. Their blood vessels are in the epidermis. Comparison of short-sighted. Relatively small and relatively fragile and easily worn due to improper puncture. At this time we should note that: first, 6 in the blood vessel of a 10 cm cuff tightly enclosed, taut skin. The blood vessels in that period was under the Author: Ganzhou, Jiangxi 341000 5 centimeters at the blood center 45. Angle into the needle. Decreased immediately after the needle into the needle point of stability to the vessel striking. Needle should pierce the blood vessel and then into the l-2 cm, should not carry too much, so as not to burst the blood vessels. Fixed needle. Example Three: In the elbow can not find the cubital fossa vein,[link widoczny dla zalogowanych], basilic vein and cephalic vein. However, about 6 cm under the elbow fossa was found at the extension of Jones Lang basilic vein basilic vein or veins parallel or cross into the vein. Then puncture to note that at this time in the elbow fossa fastened cuff. Well donors clenched fist. Pat vessels were near the location in the vessel 45 l cm. Angle point of needle puncture and then decreases blood vessels. Spines parallel to the vessel after the needle a little. The needle should not be much longer,[link widoczny dla zalogowanych], to avoid puncture blood vessels. After the fixed needle. Because small blood vessels blood donors should be told his fist at the same table that we should do in the cubital fossa at the bar cuff help donors and scratched. Example four: cubital fossa in the arm and arm can not find a positive blood vessels, they can look back in the arm. Cubital fossa in the back of the hand only to find a smaller under the blood vessels. Direction is not necessarily the same. At this time,[link widoczny dla zalogowanych], it can also be used on the root vessels. As the small blood vessels in a unique position,[link widoczny dla zalogowanych], we should have a stable state of mind and heart to be smaller. Cubital fossa in the truss in the vascular cuff next to l2 cm needle. Into the skin into the blood vessels in our position should be fixed to the needle, due to a unique position, hand held onto the needle in one hand and fist action with donors and scratched. More than a few cases are encountered in practical work the more specific the collection of blood vessels. In fact, there are many variations of the crowd waiting for us to spirits looking for blood and discovery. In normal practice as long as we accumulate more experience in. Certainly can improve the rate of a blood collection needle. To improve the rate of a blood collection needle is not an easy thing done, I think it is more important is to spend more time before the needle and effort to find a most certain vascular puncture. This is usually the work by the continuous accumulation. Book of Clinical Cytology news professional Chinese Anti-Cancer Association, vice chairman.
