How to eliminate bruises after blood draw during physical examination

After a physical examination, bruising can be eliminated through local cold compress, alternating hot compress, medication application, moderate activity, nutritional supplementation, and other methods. Bruising is usually caused by factors such as delayed absorption of subcutaneous bleeding, increased fragility of blood vessels, and improper compression.

1. Local cold compress

Within 24 hours after drawing blood, a towel wrapped in an ice pack can be used to apply cold compress to the bruised area, 10-15 minutes each time, repeated 1-2 hours apart. Low temperature can constrict blood vessels, reduce bleeding, and alleviate swelling and pain. Avoid direct contact of ice cubes with the skin to prevent frostbite.

2. Alternating hot compress

After 24 hours, switch to hot compress and apply a warm towel at around 40 ℃ to the bruised area, 15-20 minutes each time, 3-4 times a day. Hot compress promotes local blood circulation and accelerates the dissipation of congestion. It can be alternated with cold compress to enhance the effect.

3. Medication application

Follow the doctor's advice to use topical medications such as polysaccharide sulfate cream, heparin sodium cream, and blood activating pain relieving cream. Polysulfonic acid adhesive polysaccharide cream can have anti-inflammatory and anti-inflammatory effects, heparin sodium cream can inhibit thrombus formation, and blood activating and pain relieving cream can help remove blood stasis and disperse nodules. Avoid damaging the skin when applying.

4. Moderate activity

Avoid immediately lifting heavy objects or engaging in vigorous exercise after drawing blood, but it is possible to appropriately move the upper limbs to promote blood circulation. Gentle movements such as slowly rotating the wrist and clenching fists to relax, 3-5 times a day for 5 minutes each time, can help to reduce bruising.

5. Nutritional supplementation

increases the intake of vitamin C and vitamin K, such as kiwifruit, spinach, broccoli, etc. Vitamin C enhances vascular elasticity, while vitamin K participates in the coagulation process. At the same time, ensuring high-quality protein intake such as eggs and fish promotes tissue repair. After drawing blood, the needle should be pressed for 5-10 minutes until there is no bleeding, and the puncture site should be avoided from rubbing for 24 hours. The bruising usually subsides on its own within 1-2 weeks. If accompanied by severe pain, darkening of the skin, or expansion of the area, it is necessary to seek medical attention promptly to rule out diseases such as coagulation dysfunction. Pay attention to avoiding bumps in daily life and wear loose clothing to reduce friction.
