Passerby A said to Passerby B, "Don't ever ask that nurse to draw your blood. After she did, my hand got a big bruise." In fact, was there really something wrong with the nurse's blood drawing? We can check according to the following precautions to avoid bruises and hematomas after blood drawing! 1. Wrong pressing posture Correct posture: Do not bend your elbows, cover the blood collection site with a sterile cotton swab, cotton ball or gauze, and use three fingers to press the blood collection point and above. Wrong posture: Pressing with bent elbows will add extra pressure, leading to an increased risk of bleeding, bruising, pain, etc. 2. Not pressing for long enough Correct: Continue pressing for 5-10 minutes; If hematoma occurs or bleeding lasts for more than 5 minutes despite correct pressure to stop bleeding, the clinician can evaluate and treat the patient's coagulation function. Mistake: Rubbing the needle eye or removing the covering such as cotton balls from time to time to have a look. 3. Wearing clothes with tight sleeves when drawing blood 4. Use this arm to lift heavy objects after blood drawing For hematoma or bruise that has already formed, cold compress can be applied within 24 hours to stop the bleeding, and the limb on that side should be prevented from lifting heavy objects. Hot compress can be applied after 24 hours to promote the absorption of blood stasis. |
