Abstract: Objective To evaluate the effect of preventive nursing on reducing the occurrence of hemodialysis hypotension in hemodialysis patients. Methods A total of 86 hemodialysis patients from April 2016 to December 2019 were selected and randomly divided into two groups by random number table, with 43 cases in each group. The control group received routine nursing, while the study group received preventive care additionally. The incidence of hypotension, the change of blood pressure, and the score of negative emotion were observed. Results After one course of dialysis treatment, the incidence rate of hypotension in the study group （6.98%） was lower than that in the control group （15.57%） （P<0.05）. There was no significant difference in systolic blood pressure, diastolic blood pressure, and mean arterial pressure between the two groups before intervention （P>0.05）, but after intervention, the three indicators in the study group were higher than those in the control group （P<0.05）. There was no significant difference in SDS and SAS scores between the two groups before intervention （P>0.05）, but after intervention, the two scores of the two groups decreased, and were lower in the study group than in the control group （P<0.05）. Conclusion Preventive nursing care can produce good effect among the patients undergoing hemodialysis, including effectively preventing hypotension, controlling blood pressure, and relieving negative emotions.
