What medication should be used for skin ulceration and infection caused by adhesive plasters?

In general, commonly used medications for skin ulcers and infections caused by adhesive plasters include mupirocin ointment, erythromycin ointment, fusidic acid cream, kangfuxin solution, and povidone-iodine. Specific analyses are as follows:

1. Mupirocin Ointment: This is a topical antibiotic ointment that effectively inhibits bacterial proliferation causing skin infections, reduces inflammatory responses at ulcerated sites, and promotes wound healing. It is suitable for mild to moderate cases of skin ulceration and infection.

2. Erythromycin Ointment: With antibacterial and anti-inflammatory properties, this ointment is relatively gentle. It helps alleviate redness, swelling, and pain at ulcerated areas, prevents the spread of infection, and forms a protective film over the wound to create an optimal environment for skin repair. It is ideal for sensitive skin or minor ulcerations.

3. Fusidic Acid Cream: This medication inhibits bacterial protein synthesis, providing potent antibacterial effects. It effectively controls bacterial infections in ulcerated areas, reduces inflammation, relieves pain, and aids rapid recovery of damaged skin. It is suitable for cases with obvious signs of infection.

4. Kangfuxin Solution: A traditional Chinese medicine preparation, it promotes blood circulation, nourishes yin, and stimulates tissue regeneration. It can be directly applied or used as a wet dressing on ulcerated wounds to encourage granulation tissue growth, accelerate skin repair, and reduce scar formation. It is particularly suitable for deep ulcers or wounds with slow healing.

5. Povidone-Iodine: With broad-spectrum antimicrobial activity, it kills bacteria, fungi, and other pathogens. Due to its low irritation, it can be used for daily disinfection of ulcerated and infected areas to prevent worsening of infection, laying the foundation for subsequent treatments and wound healing.

Prior to applying any medication, the ulcerated wound should be cleaned with normal saline to remove secretions and residual drugs. Medications should be applied gently to avoid irritating the wound. If the ulcerated area expands, infection worsens, or systemic symptoms such as fever develop, medical attention should be sought immediately.
