尿毒症患者多伴有血压异常，大多数合并高血压，少数伴有低血压。另外，血液透析可使各种血管活性物质的水平发生较大变化，更会影响到尿毒症血透患者的血压。我们对30倒尿毒症血透患者及28N尿毒症非透析患者予以24小时动态血压监测（A13PM），旨在观察尿毒症血透患者的昼夜血 Patients with uremia are often associated with abnormal blood pressure, most with hypertension, a few with hypotension. In addition, hemodialysis can make a wide range of changes in the level of a variety of vasoactive substances, but also affect the blood pressure of patients with uremia hemodialysis. We administered 24-hour ambulatory blood pressure (A13PM) to 30 patients with uremic hemodialysis and 28-n uremic non-hemodialysis for the purpose of observing the circadian blood pressure in patients with uremia hemodialysis
