초록
조영제 사용으로 유발된 중증 저나트륨혈증이 일어난 경우는 매우 드물다. 저자들은 조영제를 사용한 복부전산화단층촬영을 시행했던 환아에서 중증 저나트륨혈증과 경련이 발생하였으나, 신경학적 검사에서 특별한 이상이 발견되지 않았고, 조영제 이외의 저나트륨혈증의 다른 원인을 발견할 수 없었던 환자를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
Abstract
Hyponatremia which is a very common electrolyte abnormality in hospitalized patients is defined as a plasma sodium concentration less than 135 mEq/L. Hyponatremia is generally caused by intravascular volume depletion, excessive salt loss and hypotonic fluid overload. It also can be caused by intravascular osmotic agent. Although most cases are mild and asymptomatic, acute severe hyponatremia can cause severe neurologic symptoms, such as seizures and coma. We report a rare case of severe hyponatremia induced by radiographic contrast agent.
