Hemodiafiltration's clinical treatment on refractotory hypertension of uremia patients

Objective To compare the HDF with standard blood dialysis treatment of chronic renal failure (CRF) in patients with refractory hypertension and its mechanism.ethod sixty cases of CRF in patients with refractory hypertension were randomly divided nto 2 groups.A group(HD),3 times a week application standard hemodialysis treatment:B roup (HDF),1st week trip conventional HD treatment and 2 times per week HDF treatment.omparing the two groups of patients before treatment and after treatment for 8 weeks arathyroid hormone(iPTH),plasma renin(RA),angiotensin II(Ang II),mean arterial pressure.Result B patients iPTH,plasma renin(RA),angiotensin II(Ang II)than the A group weresignificantlY decreased mean arterial blood pressure also dropped significantly more.Conclusion Hemodiafiltration can effectively remove plasma PA,Ang II,parathyroid hormone (iPTH),and other elements of toxins,the treatment of refractory high blood pressure is more effective than hemodialysis,worthy to be popularized.
