The number of diabetic foot patients with lower limb arterial occlusive disease is increasing. Lower extremity arteriosclerotic occlusion is prone to lower extremity ischemia, the feet will be cold and painful and cold, there are many people with hot water foot soak, or even find some foot soak remedy treatment. I tell you, for patients with vascular disease, there is no prescription, foot soak often brings about the aggravation or deterioration of the condition, or even disaster. What is going on? Although the performance of lower limb arterial occlusion is lower limb ischemia, unfortunately, hot water soaking feet, and can not expand the occluded blood vessels. Because the temporary increase in foot temperature at the same time, local metabolism will also increase, tissue oxygen consumption increases, but the blood supply can not effectively increase. Thus, local heating will only aggravate tissue hypoxia, and in some cases lead to lesions. And not only foot soaking can not be used, like infrared heat therapy with heating effect, etc. also can not. We all know that diabetic foot is divided into neuropathic, ischemic and mixed type, foot soaking is likely to aggravate the condition of ischemic and mixed type patients. And for gangrene caused by neuropathy, which can manifest itself as a fear of cold, hot water foot soaking can easily become a comfortable option. The tragedy is that once neuropathy is present, the patient’s sensory feedback mechanisms for pain and water temperature fail. Patients therefore tend to keep heating the water, even if they have been severely scalded, unaware of it. Many of the scalded patients admitted to our hospital are because they can’t feel the change in water temperature, soak and wash their feet or do fire therapy, foot burns can’t be found in time, can’t be effectively treated, wound infection intensifies, most patients are facing amputation encounters. Knowing this, it is recommended that before soaking your feet, it is clear whether you still have the conditions for hot water foot soaking. If there has been lower limb arterial occlusive disease, do not try hot water or treatment of leg and foot pain recipe foot soak, so as not to cause irreparable disaster to themselves.
