| 【 要旨 】 | 透析液ナトリウム(Na)濃度は，除水をいかに安定して行うかを目的として変更されてきた．それにはダイアライザ除去性能の向上，透析機器の進歩と関連しており，現在は正Na透析液(140mEq/l)に集約された．一方，透析液カルシウム(Ca)濃度は腎性骨症に対する治療方針の変遷とともに変更され，Ca濃度2.5,3.5,3.O,2.5mEq/lと変化した．現在なお低Ca透析液(2.5mEq/l)の優位性は確立していない．今後は，個々の症例に合った処方透析のあり方を考える必要がある． | |

| [ Summary ] | Concerning dialysate Na concentrations, which have changed when they became stabilized through ultrafiltration. This is related to improvements in dialyzer performance. This information was gathered by analyzing Na concentrations of 140 mEq/l. On the other hand, dialysate Ca concentrations were changed with treatment policies for renal osteodystrophy. Ca concentrations were 2.5 mEq/l at first, but it changed to 3.5, 3.0 mEq/l afterwards. Low Ca levels (2.5 mEq/l) were used again. However, this does not establish the prepotency of low Ca dialysate currently in use. We need to think about circumstances concerning the composition of dialysates, which relate to individual dialysis prescriptions in the future. |
