I said today that the family of this case is in the process of referral for the patient, who is in the following situation: the fracture of the right lower leg occurred about a month ago, when there was a long strip of wound, the lower limb fracture was fixed, and the wound was also closed with 14 stitches. Now the situation is that the fracture has grown back, but the sutured wound is not optimistic. The wound is locally dark, surrounded by redness and swelling, with cloudy-like fluid exuding from some areas, and the patient feels pain. This condition is actually characteristic of an infected wound, and the first thing to do is to examine the wound. The first thing to do is to go to the secretion for bacterial culture, the purpose is to determine whether to use antibiotics and what antibiotics to use. It is also necessary to do a blood count, whether it is anemic, etc. There is also an examination of the blood vessels of the lower extremities and what the extent of the lesion is. If the patient has symptoms of fever, it is important to look at indicators related to infection such as white blood cells, at which point antibiotics need to be administered empirically first (this needs to be seen by a doctor experienced in treatment, and not handled well by an inexperienced doctor). One more thing is that the suture opening needs to be opened to explore the depth of the infection. This process requires a professional stoma therapist to debride the wound and clean out the necrotic inflammatory tissue. If there are large blood vessels or tendons around, it is also necessary to check whether the infection has spread along the blood vessels and tendons, which is the biggest risk, because it can develop very quickly and is particularly harmful. There is also a possibility that if the infection is probing deeper and there is a bone infection, then this situation still requires local radiographs with the aim of ruling out the possibility of osteomyelitis. Osteomyelitis is very common in diabetic foot and is also very dangerous. In the examination of the patient, it is necessary to clarify the presence of osteomyelitis first, which has a particularly great impact on the development of the treatment plan, otherwise the effect is not good if it is not symptomatic. Of course, these are the first tests that should be done for the above-mentioned patients. The family of the patient said that many of the local doctors did not do it and no longer believed it, and then wanted to visit us. Of course, the above examination items, but also from person to person, in the development of the examination program is also based on the characteristics of different patients to decide, first clear the patient’s situation, only to facilitate the development of targeted treatment programs.
