The diabetic foot is one of the serious complications of diabetic peripheral vascular neuropathy and an important cause of disability, death and incapacity in diabetic patients. Amputation due to diabetic foot greatly affects patients’ own quality of life and life expectancy, and also causes heavy burden to families and society. In recent years, the incidence of diabetes has been increasing year by year, and the incidence of diabetic foot has also been increasing. The onset of the disease is mainly related to the three major factors of diabetic neuropathy, vascular disease and infection, and its main manifestations are: numbness and coolness of the foot, swelling or purple, decreased sensation, pain, ulcers and gangrene, decreased resistance to infection, slow wound healing, and sometimes even failure to heal and amputation, so foot care is very important, and the nursing experience is summarized as follows: Active control of diabetes Diet therapy is the basic diabetic Diabetes treatment is the basic measure of diabetes. According to the patient’s weight, age and activity, the daily diet should be calculated in order to achieve a balance between caloric intake and energy consumption. In principle, eating should be regular and quantitative, with 1/3 of the food quantity distributed in the morning, midday and evening, and full meals should be avoided. Patients with diabetic foot necrosis should enhance calorie consumption by 10% – 20% due to infection, and diversify recipes according to patients’ dietary habits. Monitor blood glucose, adjust the dose of insulin according to the change of blood glucose, and control blood glucose close to the normal level, and the improvement of disease is beneficial to the recovery of local lesions. Improve local blood circulation Observe the skin performance Check the foot daily. Pay attention to whether there are blisters, abrasions, lacerations, local skin redness, skin color and temperature, pulsation and elasticity of dorsal foot arteries. If the skin temperature decreases and the extremities become cold, the skin gradually turns white or from dark red to dark purple or even purple-black, and the pulsation of the dorsalis pedis artery gradually decreases or fades, it indicates that the local ischemia and hypoxia are serious, and ulcers and gangrene are likely to appear. Local skin care Due to the pathophysiological changes of diabetes mellitus, the skin microcirculation disorder makes the skin barrier defense ability decrease, and infection easily occurs. Therefore, it is crucial to take good care of the skin of diabetic patients. Keep the feet clean and dry. Every day with soft soap, warm water 39 – 40 ℃ soak feet for 20 minutes after washing with a soft towel to gently dry the foot skin, do not rub hard. People with sweaty feet can smear some talcum powder between the toes; and especially dry people properly smear skin care products, applied to the surface skin of the foot (can not be applied between the toes). Itchy skin or tinea pedis should not be scratched; foot massage several times a day, gentle movements, should start from the tip of the toe up massage, can promote blood circulation in the affected limbs; told the patient shoes and socks should be loose, comfortable. Because of the skin microcirculation disorders, pay attention to limb warming when cold, but do not use hot water bags to keep hot compresses to prevent burns and blisters. For foot infections, use Chinese herbal medicine to soak the feet. Take the herbal medicine that warms the yang and benefits the qi, activates the blood circulation and detoxifies the toxin and boil it for 20 minutes on a civilian fire, then soak the feet when the temperature drops to about 50℃. Care of skin blisters Diabetic blister disease is a risk factor for inducing extremity gangrene, which occurs at the ends of the extremities and in areas with poor circulation, and is generally round or oval in shape, varying in size, and prone to co-infection when not handled properly. Patients with blisters and tinea pedis can have their feet soaked in 1:5000 potassium permanganate solution 3 times a day for no more than 1 week. Keep the blister area clean, avoid incision for tense blisters, and extract the exudate under aseptic operation to prevent secondary infection. The scab formed after the blister dries up can prevent infection by using its protective effect and allowing it to fall off naturally, do not peel it off. Trauma treatment The infected trauma should be changed daily, and sensitive antibiotics can be selected locally according to the thick juice culture. If the trauma is seriously infected with flesh and pus, it should be incised and drained or thoroughly cleared. After routine disinfection of the trauma surface, rinse with saline or furacilin solution, and locally irradiate with infrared lamp at a distance of 30-50M twice a day for 15 minutes, mainly to promote blood circulation and granulation growth, and also apply silver sulfadiazine powder, vitamin E, and nano-silver gel externally to the trauma surface to promote drying, muscle growth, and blood circulation and siltation; also use comfrey oil gauze for dressing change, once a day. 1 time. After the above active treatment and care, if the patient still appears systemic toxemia symptoms and the infection foci are obviously enlarged and the healthy parts have obvious boundaries, the appropriate adequate amount of broad-spectrum antibiotics should be given systemically according to the drug sensitivity test. If the infection cannot be controlled, the limb should be amputated promptly. Advise diabetic patients to do calf and foot exercises for 30 – 60 minutes daily, such as leg shaking, heel-to-toe exercises, squatting. Usually elevating the affected limb to facilitate blood return can improve blood circulation in the lower limbs. Psychological care diabetic patients due to foot infection gangrene, accompanied by bad odor, patients often have low self-esteem, in addition, some people are prone to anxiety because of the long hospitalization, nursing staff and family members should be more comfort, more encouragement to patients. The nursing staff and family members should comfort and encourage the patients. The appropriate guidance will make the patients stable and cooperate with the treatment. Family health education Diabetes education can improve patients’ knowledge of diabetes and compliance with treatment, thus reducing the incidence of various chronic complications and the rate of disability and death. Education of patients’ families has an important position in diabetes management and treatment. In the care, patients who can accept the guidance of medical staff well, adhere to diet control and exercise therapy, and monitor blood glucose carefully so that the blood glucose control is stable, the disease recovers quickly. If the patient’s family members do not cooperate well, so that the patient’s long-term diet is irregular and blood glucose control has been unstable, resulting in long-term failure to heal the diabetic foot, and finally the possibility of death due to limb gangrene and sepsis will increase significantly. Therefore, in the process of diabetic foot care, family members and nursing staff provide patients with all-round care from psychological techniques to family society through all-round systematic care, which is important for patients to control blood sugar and improve their quality of life.
