Doctor's answer:

Treatment Principles
The treatment of pressure ulcers should be initiated early. The principle is to relieve pressure on the affected area, promote local blood circulation, and enhance wound care. For stage I pressure ulcers, regular massage, position changes, local alcohol application, or infrared irradiation should be performed. If inflammation is significant, a 0.5% neomycin solution can be used for wet dressing. For stage II pressure ulcers, antibiotic ointment can be applied externally, followed by covering with sterile gauze.
