Clinial Research on Patients with Hemodialysis-associated Hypotension

Objective To explore the mechanisms,prevention and treatment of hypotension during hemodialysis.Methods The clinical data of 40 patients with maintaining hemodialysis were collected,they were divided into hypotension group(n=17) and control group(n=23) according to hemodialytic hypotension existing whether or not.The etiopathogenesis,age,weight growth rate in hemodialysis period,ultrafiltration(UFV),ultrafiltration rate(UFR),serum natrium(Na+),albumin(Alb),hemoglobin(Hb),blood urea nitrogren(BUN),serum creatinnine(Scr) in hemodialysis period were compared between the two group.Results Compared with the control group,the aged complicated with diabetes,left ventriculiar hypertroply,arteriosclerosic were apt to produce hemodialytic hypotension(P0.01);the weight growth rate(%),UFV,UFR existed statistic difference(P0.01);there is also statistic difference between two group on Na+,Alb,Hb(P0.05);but no difference existed on BUN,Scr(P0.05).Conclusions To prevent hypotension during dialysis,some measures should be taken:controlling weight growth rate between hemodialysis period,stepping down the speed of ultrafiltration,changing the method of blood purification,then adoptting the sequential natrium dialysate,cool dialysate,proper medicated and improving heart function,correcting anaemia,hypoproteinemia,cacotrophia,and so on.
