ABSTRACT
The syndrome of inappropriate antidiuretic hormone secretion is a disorder in which water secretion is partially affected because of the body’s inability to adequately suppress the secretion of antidiuretic hormone; this retention leads to hyponatremia. The resemblance between oxytocin and the antidiuretic hormone can make the former have similar effects to the latter when using it at high doses (more than 15 mU/minute) during labor conduction , causing acute retention of urine and, therefore, dilutional hyponatremia. We present an atypical case of the syndrome of inappropriate antidiuretic hormone secretion associated with the administration of low dosages of oxytocin during labor conduction through a short period of time (6 mU/min during 3 hours). The conduction of labor with oxytocin is a common practice in obstetric services. High dosages of this hormone may produce acute water intoxication and dilutional hyponatremia, because of the similarity of its structure with that of the antidiuretic hormone, presenting itself with unspecific neurological alterations.
