Iodine compounds and silver compounds can be used in case of infection, and non-steroidal anti-inflammatory drugs, such as ibuprofen and naproxen, can be used in case of severe pain. 2. Surgical treatment: Decubitus ulcers can also be treated with surgical debridement and skin repair, which involves removing the wound completely and covering it with other healthy skin tissue. 3. Physical therapy: Decubitus ulcers can also be treated with physical methods, including electrical stimulation, magnetic fields, pulsed radio frequency energy and phototherapy, and also with bioenergetic energy, such as high frequency and low frequency ultrasound.
