Why Do I Have Bruises on My Wrist After Surgery?

Postoperative wrist bruising may be caused by local compression, excessive tightening of wristbands, capillary rupture, secondary infection, coagulation dysfunction, and other factors. It is recommended to seek medical attention promptly, and after clarifying the cause, corresponding treatment measures should be taken under the guidance of a doctor. The following is a detailed analysis:

1. Local Compression:

During surgery, patients are often unconscious and maintain the same position for an extended period. Compression of the wrist can lead to a significant accumulation of blood beneath the skin, resulting in a bluish discoloration, i.e., bruising. This typically does not cause significant discomfort and does not require special treatment, as it will usually resolve spontaneously.

2. Tight Wristband:

To prevent patient movement during surgery, wristbands may be used to secure the wrist to the operating table. If the wristband is tied too tightly, it can impede local blood circulation, leading to wrist bruising. Pain may be felt initially but will subside with time. For this situation, patients can apply a warm compress (using a towel soaked in water at approximately 45°C) to the affected area for about 20 minutes, repeating this 3-4 times a day.

3. Capillary Rupture:

If intravenous anesthesia is required during surgery, venous puncture may be performed, which can damage subcutaneous capillaries, causing a small amount of blood to accumulate beneath the skin and result in wrist bruising. Some patients may experience significant pain upon pressing the affected area. Special treatment is generally not required, as the bruising will resolve spontaneously.

4. Secondary Infection:

Failure to properly disinfect the area after venous puncture or surgery can lead to secondary infection. Inflammatory factors stimulate surrounding tissues, causing bruising and possibly wound redness and swelling. Patients can disinfect the area with iodine and, if necessary, take medications such as Amoxicillin Capsules, Ceftriaxone Tablets, or Azithromycin Tablets under medical guidance.

5. Coagulation Dysfunction:

This refers to a lack or insufficiency of coagulation factors in the body, leading to increased bleeding after trauma. Some patients may frequently experience skin bruising, which is not directly related to surgery. If bruising occurs in isolation, special treatment is generally not required, but patients should regularly monitor their health status through medical check-ups.

The causes of postoperative wrist bruising vary, and treatment approaches will differ accordingly. During treatment, patients should take precautions to protect the wrist and avoid further compression for a short period. If symptoms persist or worsen, patients should promptly inform their doctor to address the underlying cause.
