【摘要】 观察了20例尿毒症维持性血液透析患者在其他成分浓度不变,而镁离子浓度改变的情况下的透析效果,发现用镁0.5 mmol/L透析液透析时病人血压升高,心率增快,手足抽搐伴低血镁、低血钾、低血钙。用镁为1.0 mmol/L时,血压、心率均有不同程度减低,但仍有手足抽搐伴高血镁、高血钾、低血钙。而用镁0.96 mmol/L心率血压变化不大,无手足抽搐。血镁、血钾、血钙均正常。更多还原

【Abstract】 The therapeutic effect of continuous hemodialysis in 20 cases of the patients with uremia was observed when concentration of magnesium in the dialysis fluid was changed without change of the concentrations of other constituents in the dialysate. It was found that when 0.5 mmol/ L of magnesium was used the hypomagnesemia, hypokaliemia and hypocalcemia occured followed by the elevated blood pressure, increased rate of heart and tetany in the patients. When dialysed with 1.0 mmol/L of magnesium the patients’blood pressure and heart rate were found to decrease to different extent, but the tetany with hypermagnesemia, hypeskaliemia and hypocalcemia still existed. In case of using 0.96 mmol/L of magnesium in the dialysate the blood pressuse and the heart rate were little changed, the concentrations of magnesium, potassium and calcium in the plasma remained normal, and the tetany did not appear any more.更多还原
