To determine the incidence of intradialytic hypertension (IDH) during hemodialysis (HD) in end-stage renal disease (ESRD) patients using acetate dialysate compared to those using bicarbonate dialysate. This study was a double-blind cross-over randomized clinical trial. The effect of acetate and bicarbonate dialysate on blood pressure was analyzed in two consecutive HD sessions. The selected subjects were 41 stable ESRD patients scheduled for dialysis 2 times/week/from the HD unit of Dr.Soetom Hospital Surabaya, aged between 21-65 years old, with a hemoglobin level > or = 7 g/dL, serum albumin > or = 3 mg/dL and interdialytic weight gain < 4 Kg, and an average Qb 150-250 ml/minute. The dialysate sodium level was 138 mEq/L/ The study subjects were divided into tow groups: 21 patients in the group who received Acetate on the first session and Bicarbonate on the next (AB) and 20 patients in the group receiving Bicarbonate first (BA). Comparison of IDH during use of each dialysate was analyzed by Chi-Square and Mc Nemar Chi-Square test. No characteristic differences were found in both groups: HD duration (for AB) was 28.83 +/- 13.89 vs. 34.95 +/- 24.80 months (for BA) (p = 0.333); Age (for AB) was 47.61 +/- 9.49 vs. 47.75 +/- 11.80 years (for BA) (p = 0.969); Hemoglobin (Hb) level (for AB) 8.19 +/- 0.84 vs. 7.94 +/- 0.41 mg/dL (for BA) (p = 0.238); serum Albumin (for AB) was 3.79 +/- 0.26 vs. 3.82 +/- 0.30 g/dl (for BA) (p = 0.652). The number of patients with IDH during acetate dialysate with IDH during bicarbonate dialysate was 1 (2.4%). Overall, there were 11 patients with Diabetic Kidney Disease (26.8%). Six out of them (54.5%) had IDH during acetate dialysate and only and 1 patient (9.1%) had IDH during acetate and bicarbonate. The incidence of IDH in hemodialysis using acetate is significantly greater than that when bicarbonate is used (p = 0.000).
