Intra‐operative diagnosis of hypopituitarism in a patient undergoing radical nephrectomy

Abstract

A 43-year-old woman presented for elective radical nephrectomy. After induction of anaesthesia, she developed hypotension that failed to respond to standard treatment measures. Her core temperature decreased to 34 degrees C in spite of active warming. She required very low concentrations of anaesthetic agents to maintain an adequate depth of anaesthesia for abdominal surgery. After excluding the common causes of hypotension, the possibility of subclinical hypopituitarism was considered and subsequently confirmed.
