Pregnancy in panhypopituitarism

The case of a 30-year-old pregnant patient suffering from panhypopituitarism is presented. Pregnancy induced by HMG/HCG had been uneventful. Induction of labor by PGE2 vaginal tablets and by intravenous oxytocin at 42 gestational weeks failed and the patient was operated. Following the operation severe exacerbation of her diabetes insipidus occurred. Fluid balance mechanism failed and electrolyte status deteriorated rapidly. The importance of pitressin in maintenance of fluid and electrolyte balance in panhypopituitaric patients in labor and surgical trauma is stressed.
