The last thing you want to see in diabetic foot is amputation, but there are still many, many patients who undergo amputation for various reasons. Do you know what is a very common problem after surgery? Re-infection of the wound! Recently, a typical patient consulted our diabetic foot specialist and asked what to do in this case! Continued wound ulceration and infection is a surgical failure. The current indications for surgery in most hospitals are wound infection, lower extremity vascular occlusion, etc., especially vascular problems, to operate often where the blood vessels are blocked. There is a typical case where the patient just has a dry gangrene of one toe, and the examination of the blood vessels below the knee is bad, stage occlusion, and the doctor’s plan is to operate at least at the knee position for fear of re-infection because of blood obstruction after surgery. But this did not prevent re-infection, which is determined by the characteristics of diabetes itself. Diabetic patients are inherently difficult to heal wounds, and wounds after amputation are equally risky. Moreover, the wound is often sutured after surgery, and the postoperative wound cannot be strictly controlled for sterility, and surviving anaerobic bacteria can harbor infection. Surgery is usually done in orthopedics or surgery, and they often still treat diabetic wounds along the lines of general surgery, with shortcomings in blood sugar control and metabolic disorders, making it difficult to develop a thorough plan, which can lead to acute and chronic complications if blood sugar gets out of control. Also, many diabetic foot patients will be combined with cardiovascular, cerebrovascular, kidney disease and other health problems (there are so many patients who did not undergo surgery because of such problems and were later cured through treatment), all of which will more or less have an impact on the foot wound and are the cause of recurrence. So, what should I do if there is a wound reinfection after amputation? Remember that you must not operate again, otherwise you will still repeat the same situation as the first time. Recommend the use of a combination of Chinese and Western medicine conservative treatment methods, Western medicine to control infection, improve the patient’s physical quality, treatment of cardiovascular and cerebrovascular diseases, improve resistance, etc., Chinese medicine topical local wound, dispel decay and muscle, blood circulation, improve local tissue blood circulation, through comprehensive conditioning, enhance the local wound resistance and immunity, it has been proven to allow the purpose of wound healing. The therapeutic effect of TCM cannot be ignored, but remember that it is not simply a matter of washing and soaking the feet with TCM water or applying it directly, but the treatment before and after is coherent and systematic, such as debridement, infection control, improvement of circulation, nourishment of the wound surface and elimination of decay and growth of muscle, etc., and each step must be handled well in order to truly achieve the desired therapeutic effect.
