Abstract: Objective To investigate the influence of limb behavioral norms on the complications of internal fistula in maintenance hemodialysis (MHD) patients Methods Thirty-one MHD patients who received arteriovenous fistula (AVF) for the first time in our hospital from Jun. 2014 to Dec. 2014 were selected as the control group, and 33 MHD patients who received AVF for the first time in our hospital from Jan. 2015 to Jun. 2015 as observation group. The control group adopted the traditional health education, and the observation group established more detailed norms of physical behavior. The fistula complications were compared between
the two groups after one year. Results After one year, the incidence of thrombosis (χ2=4.399, P=0.036), stenosis and occlusion (χ2=4.373, P=0.037), decreased blood flow in AVF (χ2=4.510, P=0.034) were significantly lower in observation group than in control group, and the differences were statistically significant. Fistula infection was not statistically significant (χ2=1.081, P=0.298) between the two groups. Conclusion The establishment of limb behavioral norms can reduce the incidence of fistula thrombosis, occlusion and fistula blood flow reduction in MHD patients.
