Abstract：Objective To investigate the influence of reduced pressure puncture method on utilization of autogenous arteriovenous fistula(AVF)at initial stage. Methods Totally 35 patients undergoing AVF were assigned to the control group(n=17)and the study group(n=18). In the control group, the conventional pressure puncture method was carried out to establish the AVF, while the reduced pressure puncture method was provided in the observation group. The success rate of puncture, incidence of hematoma and errhysis at initial stages of AVF utilization(first 10 times of puncture)were observed. Results The one-time success rate of puncture was higher in the study group than that of controls(P0.05). The incidence of subcutaneous hematoma was lower in the study group than that of controls(P0.05). There was no significant difference in incidence of errhysis between two groups(P0.05). Conclusion Reduced pressure puncture method is an effective way of ensure utilization of AVF at initial stage and reduce the risk of subcutaneous hematoma.
