Abstract: Objective To investigate the risk factors of hypertension in maintenance heamodialysis (MHD) patients, and to improve hypertension control through the intervention of intensive medical care and health education. Methods Questionnaires about hypertension was conducted in a total of 177 patients on MHD. According to the results of questionnaires, the risk factors of hypertension were analyzed. Medical care and health education on these risk factors were then conducted. Results In the 177 patients, 112 were complicated with hypertension. The patients with hypertension were divided into two groups based on the blood pressure before dialysis: controlled group (blood pressure ≤140/90mmHg, n=44) and uncontrolled group (blood pressure >140/90mmHg, n=68). The percentage of weight gain between dialysis was higher in uncontrolled group than in controlled group. After two months of intensive medical care, the amount of weight gain between dialysis reduced in the uncontrolled group, and control of hypertension achieved in more patients. Conclusion Hypertension is a common feature in MHD patients, and uncontrolled hypertension exists in most of them. Medical care and health education are effective for these patients to control the interdialysis weight gain and hypertension.
