Abstract:
Objective To provide the evidence for the clinical prevention and early treatment for the complication by testing microcirculation of the middle fingertip in renal failure patients with hemodialysis.Methods High-frequency ultrasounds combined with E-flow technique were applied to detect the Doppler velocitg index of middle fingertip's nail bed arteriole and ventral arteriole in 35 renal failure patients with hemodialysis.Peak systolic velocity(PSV),end-diastolic velocity(EDV)and vascular resistance index(RI)were separately measured,and comparison were made with healthy adults and renal failure patients without hemodialysis(sex and age matched).Results Compared with normal control,PSV and EDV of middle fingertip's nail bed arteriole and ventral arteriole were degraded statistically(P＜0.05),while RI was increased statistically(P＜0.05)in renal failure patients with and without hemodialysis.Compared with renal failure patients without hemodialysis,PSV and EDV were degraded(P＜0.05)and RI was increased(P＜0.05)in renal failure patients with hemodialysis.Conclusions High-frequency ultrasound combined with E-flow imaging technique can evaluate the microvascular peripheral resistance in renal failure patients with hemodialysis.
