1, diabetes, laboratory for various tests such as glucose, blood glucose, oral glucose tolerance testing.
2, ischemic inspection
(1) lower limb postural test in patients with diabetic foot elevation lower extremities in 30-60 seconds after the foot can be seen clearly pale skin, body
sagging purple was seen after the middle. If the venous filling time (by the foot skin turn pale ruddy time) in 15 seconds or more, indicating that the lower
limb blood supply is clearly insufficient.
(2) lower extremity arterial palpation in the country fossa (knee behind the nest) and the dorsalis pedis artery and dorsal foot at palpation States arteries
in patients with diabetic foot movement may have weakened artery Bo even disappear.
(3) limb limb blood flow image can understand the situation and vascular elasticity, but its poor accuracy.
(4) ultrasound is commonly used color Doppler (Dappler) Check femoral artery and vein, the country and the dorsalis pedis artery and vein. Can be directly
observed and be able to locate quantitative analysis of each of its sensibility and accuracy of the opposite sex who are good, is a non-invasive examination
methods.
(5) angiography can understand the scope of lower extremity vascular disease, blood flow distribution and the availability of collateral circulation.
However, this method is invasive examination, will increase the arterial blood supply insufficiency spasm so that limbs are generally only used to carry pre
-operative limb positioning checks.
3, microcirculation inspection is usually through direct observation in vivo microscopy diabetic patients fingernail fold microcirculation changes in
microcirculation abnormalities often prompted with microangiopathy.
4, electrophysiological examination applications EMG nerve conduction velocity may be the early detection of diabetic peripheral neuropathy. Diabetic
peripheral neuropathy is a diabetic foot disease is an important factor.
5, X-ray examination can be found in arterial wall calcification, osteoporosis and destruction, osteomyelitis, and bone and joint disease, usually as a
routine examination.
Diabetic Foot serious threat to health, early detection, prompt treatment is very important. Diabetes occurs when the patient's local skin blisters, sensory
loss, skin ulcers and other diseases should be timely to the hospital, the doctor will select the appropriate under the specific circumstances of the
inspection procedure for the corresponding treatment.
