Over 70 years old bedridden heel ulcers, may be bedsores, diabetic foot and other causes, can use growth factor drugs, antibacterial drugs and other drugs for treatment. 1. Decubitus ulcers: long-term bedridden due to compression and poor local blood flow, skin breakage and ulceration to form decubitus ulcers, can be used externally haloperidol powder, silver sulfadiazine emulsion, calf’s blood deprotein extracts and other medications, if the combination of fever and other manifestations, penicillin, cephalosporin, and other anti-infective drugs, the wound cleaned calf’s blood deprotein extracts can be used to promote the healing process. 2. Diabetic foot: long-term diabetes may be complicated by diabetic foot, resulting in localized abscesses and ulcers. Topical medications are similar to those used for decubitus ulcers. For those with significant local pain, Tramadol and other medications can be used as appropriate, and for those with combined infections, penicillin, cephalosporins and other anti-infective medications can be used as appropriate. Severe ischemic ulcers require surgical treatment. The above drugs need to be used under the guidance of clinicians.
