I don’t know if you know that diabetic patients have a typical wound that is difficult to heal, and if it doesn’t heal then the risk of infection will be high. Yesterday, a patient had an infection in his suture after surgery for a fracture, and the bone healed well, but the wound never healed. First of all, let’s have a brief understanding of the cause of the difficult wound healing. For example, if the blood sugar is high, the osmotic pressure inside and outside the cells of the wound will change, and as a result, the cells will lose too much nutrients and the immunity and resistance of the cells will be reduced. Then, the extracellular nutrients provide conditions for germs to flourish and the risk of infection increases. Many patients’ wounds do not heal, and the reason may also be the formation of inflammatory tissue in the wound after infection, which can prevent normal cell proliferation and healing. Of course, these are only one of them, in addition to the lack of blood, low protein, nutritional deficiencies, etc. Then, let’s talk about what to do when you encounter this kind of surgical wound not healing situation. For this case, you must first go to the hospital for a detailed examination, and then combine the patient’s situation to develop a targeted treatment plan. For example, if the blood sugar is very high, we should develop a plan to lower the blood sugar and disinfect the local wound in time; if there is ischemia in the lower limbs, we should develop a treatment to improve the circulation, which will help provide sufficient nutrients for the local area; if the wound is already infected, we should open the wound without delay and then clean the necrotic inflammatory tissue above, etc. We should develop a targeted treatment plan for the actual situation of each patient. Here I still want to emphasize the role of debridement, see more patients and families do not feel that I nagging, because most patients are difficult to cure the main reason is not debridement of the wound or debridement effect is not good, and ultimately lead to the wound is difficult to heal. The purpose of debridement is not simply to clean the necrotic tissue, but to heal the wound, taking into account the characteristics of wound healing. The general situation of wound healing requires a process, such as the need to go through the inflammatory phase, granulation phase, etc. Therefore, according to the characteristics of different periods of time to arrange debridement, our method is nibbling debridement, before each change of medicine need to debridement, and then the external application of Chinese ointment with the effect of elimination of decay and muscle, which has proved to be the best effect, the fastest healing speed. Of course, debridement is only one aspect, and as mentioned above, all health problems of the patient should be treated accordingly, so it should be a comprehensive treatment. In this case, it is advisable to go to a local professional diabetic foot or slow-trauma specialist to avoid the patient’s infection getting worse due to wrong treatment.
