RESUMO
Objective To investigate the effect of different puncture methods on dialysis adequacy in maintenance hemodialysis patients. Methods One hundred and twenty patients receiving maintenance hemodialysis were divided into the observation group and the control group according to the sequence of receiving the hemodialysis with 60 cases in each group. Patients in the observation group were treated with increasing distance arteriovenous fistula of more than 10 cm , while patients in the control group received normal dialysis care without changing the way of puncture. The difference of dialysis adequacy before and after intervention were compared between the two groups. Result The dialysis adequacy after intervention in the observation group was improved significantly compared with the control group (P<0.05). Conclusion The dialysis adequacy in patients with maintenance dialysis can be improved by increasing the puncture distance of internal arteriovenous fistula.
