目的探讨血液透析治疗中血压降低与超滤量(U FV)的关系。方法对70例慢性肾功衰竭患者血液透析治疗时进行血压监测,观察不同年龄组不同U FV与血压降低的关系。结果老年血透患者血压下降发生率明显高于青年患者(P<0.01)。结论血液透析中血压降低的发生率,随年龄增大而增高,将U FV控制在体重的3.3%以内,可减少血压降低的发生。
Objective To investigate the relationship between blood pressure reduction and ultrafiltration volume (U FV) in hemodialysis patients. Methods Blood pressure was monitored during hemodialysis in 70 patients with chronic renal failure. The relationship between different U FV and blood pressure was observed in different age groups. Results The incidence of blood pressure in elderly hemodialysis patients was significantly higher than that in young patients (P <0.01). Conclusions The incidence of hypotension during hemodialysis increases with age, and UFV is controlled within 3.3% of body weight to reduce the incidence of hypotension.
