Frequent hypotensive episodes developed in a 56-year-old man, who was receiving long-term hemodialysis therapy, at the time he had a uremic pericardial effusion. During dialysis with an inadvertent calcium infusion, however, the mean blood pressure (BP) was sustained and even rose from 93 to 133 mm Hg. During continued dialysis to restore the serum calcium level from a peak of 17.4 to 12.0 mg/dL, mean arterial pressure decreased back to 93 mm Hg. In contrast, BP had fallen in three of six preceding dialysis treatments and five of nine subsequent dialysis treatments, all at the same ultrafiltration rate. This report suggests the importance of serum calcium to BP regulation during hemodialysis.
一名56岁接受长期血液透析治疗的男性，在出现尿毒症心包积液时频繁发生低血压发作。然而，在透析过程中意外输注钙时，平均血压（BP）得以维持，甚至从93毫米汞柱升至133毫米汞柱。在继续透析以将血清钙水平从峰值17.4毫克/分升降至12.0毫克/分升的过程中，平均动脉压又降至93毫米汞柱。相比之下，在之前六次透析治疗中有三次以及随后九次透析治疗中有五次，在相同超滤率情况下血压均下降。本报告提示了血清钙在血液透析期间对血压调节的重要性。
