Abstract

The development of blood ionic changes could be precipitated in acid-base disorder and subsequent treatment. As technology for detecting circulating ionized $Mg^{2+}$ (the most interesting form with respect to physiological and biological properties) is now available in veterinary clinical medicine. This present study investigated the changes of whole blood ionized $Mg^{2+}$ correlated with acute metabolic and respiratory alkalosis in rodent model. Metabolic alkalosis was induced by intravenous infusion with $NaHCO_3$ and mechanical hyperventilation was applied for respiratory alkalosis. We founded that the blood ionized $Mg^{2+}$ could be reversibly decreased by the $NaHCO_3$-induced acute metabolic alkalosis but irreversibly increased by the mechanical hyperventilation-induced respiratory acidosis and respiratory acidosis. We suggested that the potential change in blood suggested that the potential change in blood ionized $Mg^{2+}$ should be counted in treatment of acid-base disorders.

산염기 불균형과 수반되는 치료과정에서 혈액 이온들은 변동되어 질 수 있다. 생리적 그리고 생물학적 활성을 가진 순환 이온화 $Mg^{2+}$ 측정이 수의 임상분야에도 적용되고 있다. 실험동물모델에서 급성 대사성 알칼리증 및 호흡성 알칼리증에 수반하는 혈액 이온화 $Mg^{2+}$ 변동을 관찰하였다. 대사성 알칼리증은 $NaHCO_3$ 정맥투여로 그리고 호흡성 알칼리증은 과호흡에 의해 유도하였다. 혈액 이온화 $Mg^{2+}$$NaHCO_3$에 의해 유도된 대사성 알칼리증에서는 가역적인 감소를 보인 반면, 과호흡에 의해 유도된 호흡성 알칼리증에서는 비가역적인 증가를 보였다. 따라서 산염기 불균형 치료에 있어 혈액 이온화 $Mg^{2+}$의 잠재적 변동 가능성을 고려하여야 한다고 판단된다.
