How to deal with bruising of the blood needle eye after physical examination

After the physical examination, bruising of the blood needle eye can be treated by hot compress, medication application, avoiding compression, raising the limbs, observing changes, and other methods. Bruising is usually caused by vascular damage, coagulation abnormalities, improper compression, thin and brittle skin, repeated punctures, and other reasons.

1. Hot compress

After drawing blood for 48 hours, apply hot compress to the bruised area using a 40-45 ℃ warm towel for 15-20 minutes daily. Hot compress can dilate local blood vessels, promote blood circulation, and accelerate the absorption of congestion. Pay attention to avoid scalding the skin. People with diabetes or sensory disorders should operate with caution.

2. Medication application

Follow the doctor's advice to apply polysaccharide cream or heparin sodium cream externally, gently massage 2-3 times a day until absorbed. These two drugs are effective in anticoagulation, reducing swelling and resolving blood stasis, but should not be used when the skin is damaged. If bruising is accompanied by obvious pain, diclofenac diethylamine cream can be used for a short period of time to alleviate inflammation.

3. Avoid compression

Within 24 hours after blood draw, avoid lifting heavy objects or engaging in vigorous activities to prevent the blood vessels at the needle hole from bleeding again. Sleeves should not be too tight, and pressure on bruised areas should be avoided during sleep. Individuals with abnormal coagulation function need to extend the protection time to 72 hours.

4. Raise limbs

When upper limb bruising occurs, the affected limb can be elevated above the level of the heart, using gravity to alleviate local congestion. Cooperate with active finger flexion and extension activities, maintain a raised posture for 15-20 minutes each time, and repeat 3-4 times a day.

5. Observation of Changes

Normal bruising will gradually fade and disappear within 1-2 weeks. If there is an expansion of bruising area, persistent pain, elevated skin temperature, or accompanied by fever, it may indicate infection or deep hematoma, and prompt medical examination is needed to screen for potential diseases such as thrombocytopenia. Correctly pressing the needle hole for 10-15 minutes after blood draw can prevent most bruises, and for those with poor coagulation function, it can be extended to 20 minutes. Daily intake of deep green vegetables such as spinach and broccoli, which are rich in vitamin K, can help improve coagulation function. Avoid repeated punctures at the bruised area, and it is recommended to have a blood draw interval of more than 3 days between two times. If the bruising persists for 3 weeks without subsiding or is accompanied by abnormal symptoms, further examination should be conducted in the hematology or vascular surgery department.
