Objective: Based on the theory of planned behavior, the "Internet plus " continuous nursing program was formulated, and its impact on the compliance of hemodialysis patients with fluid intake was analyzed. Methods: A total of 62 patients who underwent regular hemodialysis in the blood purification center from July to December 2021 were included， and were randomly divided into the control group and the intervention group with 31 cases in each group. The control group implemented the routine continuous nursing program to improve the compliance of liquid intake，and the intervention group implemented the "Internet plus" continuous nursing program to improve the compliance of liquid intake based on the theory of planned behavior. The scores of the liquid intake compliance, the ratio of body mass growth during dialysis to dry body mass, and the incidence of hypotension during dialysis were compared between the two groups after intervention. Results:After intervention, there were significant differences between the intervention group and the control group in the scores of fluid intake compliance, the ratio of body mass growth to body mass during dialysis, and the incidence of hypotension(P<0.05).Conclusion: The "Internet plus" continuous nursing program based on the planned behavior theory can improve the compliance of fluid intake in hemodialysis patients，and reduce the occurrence of hypotension during dialysis.
