What causes redness and itching at the cesarean section wound site?

In general, redness and itching at a cesarean section wound site may be caused by tissue repair during the healing phase, local skin dryness, folliculitis, fat liquefaction, or wound infection. If discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. Specific causes are analyzed as follows:

1. Tissue Repair During Wound Healing

During wound healing, fibroblast proliferation, new blood vessel formation, and nerve regeneration can stimulate skin receptors, leading to redness and itching. Keep the wound clean and dry, wear loose and breathable clothing, avoid scratching or friction, and apply a warm towel compress gently to relieve symptoms.

2. Local Skin Dryness

Loss of moisture in the skin surrounding the wound weakens the skin barrier, making it more susceptible to irritation and resulting in redness and itching. Apply medical-grade petroleum jelly or non-irritating moisturizing lotion, avoid using harsh cleansers, and maintain an appropriate environmental humidity level.

3. Wound Folliculitis

Inflammation caused by bacterial invasion of hair follicles around the wound may present as small red papules accompanied by itching and pain. Topical antibiotics such as mupirocin ointment or fusidic acid cream may be used under medical guidance. Oral cefuroxime axetil tablets may also be prescribed. Maintain cleanliness around the wound area.

4. Wound Fat Liquefaction

Necrosis and liquefaction of subcutaneous fat tissue can lead to exudate that irritates the wound, causing redness, itching, discharge, and sometimes an unpleasant odor. Medical intervention is required for debridement and drainage. Dressings should be changed regularly. Under medical supervision, oral amoxicillin capsules, cefaclor sustained-release tablets, or azithromycin dispersible tablets may be prescribed.

5. Wound Infection

Bacterial infection triggers inflammation, causing redness, swelling, heat, pain, and itching at the wound site; severe cases may involve pus formation. Surgical debridement is necessary to remove infected tissue. Under medical guidance, antibiotics such as levofloxacin tablets, cefprozil tablets, or metronidazole capsules may be prescribed. Enhanced postoperative wound care is essential.

In daily life, maintain cleanliness of the wound and surrounding skin; wear loose clothing to minimize friction; follow medical advice for regular dressing changes and check-ups; avoid strenuous exercise to prevent wound strain; and maintain a light, nutritious diet to promote wound healing.
