应用激光多普勒血流仪动态观察了９例糖尿病患者的指腹和足背皮肤微区血流。结果显示：（１）糖尿病组上肢皮肤血流量及血流灌注波形与非糖尿病组相比无明显差异；（２）糖尿病组下肢皮肤血流只有７２．２％的微区呈现高、低灌流相灌注，明显低于非糖尿病组（１００％），且糖尿病组下肢血流高、低灌流相持续时间及两灌流相上升和下降时间均明显长于非糖尿病组。作者认为此变化是由于糖尿病患者下肢皮肤微血管病变发生后代偿性增加血流供应而出现的结果。
Laser Doppler flowmeter was used to observe the blood flow in the dermis and dorsum of 9 diabetic patients. The results showed that: (1) There was no significant difference between upper extremity skin blood flow and blood flow perfusion in diabetes mellitus group; (2) Only 72.2% of the skin blood flow in lower extremity of diabetic group showed high and low perfusion phase Perfusion, significantly lower than non-diabetic group (100%), and the lower limb blood flow in diabetic group, the duration of low perfusion phase and the two perfusion phase rise and fall time were significantly longer than non-diabetic group. The authors believe this change is due to the compensatory increase in blood flow after diabetic skin microvascular disease occurs.
