Suspicion was now heightened implicating diabetes inspidus as the cause of her profound hypernatraemia.
The main drawback of all these procedures is high additional sodium delivery due to combined infusion of trisodium citrate and sodium bicarbonate, which may lead to hypernatraemia and metabolic alkalosis.
Hypernatraemia may be a consequence if trisodium citrate is administered and the sodium load is not taken into account (18).
Hypo- and hypernatraemia management should follow recommended guidelines; however, where ORT is possible, the process of rehydration usually allows metabolic homeostasis to be re-established.
On the fourth day the patient developed significant polyuria (150-450 ml/h) with a persistent hypernatraemia (maximum serum sodium 160 mmol/l).
Impaired level of consciousness was defined as a Glasgow Coma Scale <15, hypernatraemia as uncorrected serum sodium >150 mmol/l, hypokalaemia as serum potassium <3.
The authors propose that Peters' collapse was probably due to a combination of hyperthermia-induced fatigue which caused him to stop running; exercise-induced postural hypotension as a result of low peripheral vascular resistance; and combined cerebral effects of hyperthermia, hypertonic hypernatraemia associated with dehydration, and perhaps undiagnosed hypoglycaemia.
We propose that Peters' collapse was more likely due to a combination of hyperthermia-induced fatigue which caused him to stop running; exercise-associated postural hypotension as a result of a low peripheral vascular resistance immediately he stopped running; and combined cerebral effects of hyperthermia, hypertonic hypernatraemia associated with dehydration, and perhaps undiagnosed hypoglycaemia.
