How can early detection of signs of diabetic foot then? Recommend that you always observe the ischemic area (mainly lower limb and foot) whether the
following changes: We have found signs of diabetic foot is the key to
① consciously legs, feet cold, or do not feel the hair starting cold, but the skin temperature decreases. ② abnormal skin color, foot elevation when the
pale. Droop when the purple. ③ with skin manifestations of malnutrition, such as dry skin, hyperkeratosis, brittle, often easy to rip, thinning and shiny,
elastic bad blisters and so on. ④ limb paresthesia, such as numbness, tingling, etc. limbs touch, pain, temperature sensation diminished or disappeared. ⑤
Local body hair, nails, muscle abnormalities, such as the affected area to reduce or body hair loss, nail thickening or Cuibo deformation, improper nail
trimming is easy to cause paronychia, some foot muscle, subcutaneous tissue atrophy, interdigital joints bend . form a claw-shaped toe, foot corns or
calluses, foot deformities and other changes. ⑥ touch instep and the posterior tibial artery pulse weakening or disappearance of venous filling longer. ⑦
limb vascular ultrasound and angiography and other objective examination of vascular lesions can be found in varying degrees of luminal plaques and narrow.
After the trigger the symptoms of lower limb ischemia
The above-mentioned problems are not treated in time, some patients with certain symptoms occur because of different degrees of ischemia can be manifested as
intermittent claudication (defined as patients with lower extremity after walking some distance away from weakness, numbness, pain, and even a limp to walk,
or simply can not walk, with a break to alleviate the symptoms can continue to walk). This is an early manifestation of lower extremity ischemia. Increase
the extent of lower limb ischemia presenting with rest pain (pain from the hip to the foot generally conducted at night, aggravated), this state. As the leg
and foot ischemia, experienced minor trauma led to skin ulcers and so on is easy. Condition further development, especially the feet and lower limb gangrene
can occur, unhealed wound a long time and even skin split open flesh, carrion erosion, toe gangrene.
Medicine according to the performance of the different parts of gangrene is divided into wet, dry and mixed gangrene of three. In severe cases, gangrene,
amputation would have to accept the treatment which led to permanent disability, serious impact on patient quality of life.
