Effects of dialysate calcium concentration on calcium balance and blood pressure of maintenance hemodialysis pa-tients / 中国基层医药

ABSTRACT

Objective To investigate the acute effect of dialysate calcium concentration on calcium balance and blood pressure(BP) of maintenance hemodialysis(MHD) patients with normal serum tCa,and to provide scien- tific basis for individualized calcium concentration dialysate formula.Methods For 4 weeks,dialysate with different calcium concentrations as DCa 1.25,DCa 1.5 and DCa 1.75 was used in 15 stable MHD patients.Arterial blood pressure was measured before and after each dialysis session,and every 30 minutes during hemodialysis session.Serum total calcium and ionized calcium were assessed before and after each dialysis session with different calcium concen- trations dialysate.Results With the DCa 1.2.5,BP,serum tCa and iCa decreased as compared with pre-dialysis val- ues(P
