ObjectiveTo observe the application effects of the self-made protective sheath of arteriovenous fistula(AVF) combined with far-infrared irradiation in maintenance hemodialysis patients treated with ultra-high pressure balloon dilatation.

MethodsFifty-two maintenance hemodialysis patients with autologous AVF stenosis treated with ultra-high pressure balloon dilatation were divided into the control group and observation group using random number table method.The control group was routinely nursed with fist clenching, relaxation combined with local hot compress of internal fistula, and the observation group was nursed with the protective sheath of arteriovenous fistula to protect the limbs of the operative side combined with far-infrared radiation at the same time.The natural flow rate of fistula, incidence rate of complications, incidence rate of restenosis of fistula and nursing satisfaction were compared between two groups within 6 months after surgery.

ResultsFifty-two patients with fistula could firstly be treated with for hemodialysis after 1-3 days of operation.After 6 months of treatment, the natural flow volume of fistula and nursing satisfaction in observation group were significantly higher than those in control group(P < 0.01), the incidence rate of complications in observation group was significantly lower than that in control group(P < 0.05), and the differences of the incidence rate of restenosis between two groups was not statistically significant(P>0.05).

ConclusionThe ultra-high pressure balloon dilatation can effectively relieve the AVF stenosis.The self-made protective sheath of arteriovenous fistula combined with far-infrared radiation can significantly improve the blood flow of arteriovenous fistula, and reduce the incidence rate of complications in maintenance hemodialysis patients.
