Abstract:

Objective To investigate the effects of different nursing interventions on dialysis adequacy of patients undergoing maintenance hemodialysis. Methods Seventy-eight patients undergoing maintenance hemodialysis with online clearance monitoring (OCM) rate <1.2 were selected, and were divided into 2 groups based on the internal arteriovenous fistula spacing of 10 cm. Different nursing interventions were performed in two groups, and the OCM rates before and after intervention were observed in two groups. Results Patients in group A (internal fistula spacing >10 cm) treated with an increased blood flow volume from (245±26.65) mL/min to (275±23.61) mL/min were observed to have the elevation of OCM rate from 1.14±0.12 to 1.48±0.21 (P<0.05), and the correlation analysis indicated a significant correlation between increased blood flow and elevated OCM rate. Patients in group B (internal fistula spacing ≤10 cm) treated with an enlargement of internal fistula spacing from (6.67±2.76) cm to (10.43±2.94) cm were observed to have the elevation of OCM rate from 1.12±0.10 to 1.43±0.15 (P<0.05). Conclusion Either increase in blood flow or enlargement in internal fistula spacing can improve the dialysis adequacy of patients undergoing maintenance hemodialysis.
