Hypernatraemia and tonicity balance

Hypernatraemia in hospital populations.

Hemodilution, Tonicity, and Blood Viscosity.

Since the introduction of intravenous therapy, fluids containing glucose or saline in relatively isotonic concentrations have far exceeded others in use. Within the last decade new techniques in many areas of diagnosis and treatment have required that fluids of various tonicity and viscosity be introduced into the blood stream with such rapidity or in such great volume as to preclude adequate d...

Glucose polymer regimens and hypernatraemia.

A 3 year old boy who had glutaric aciduria diagnosed at 22 months of age was admitted with a history of lethargy, vomiting, and fever. He had been receiving glucose polymers as part of his dietary management. He was severely hypernatraemic, but after resuscitation and rehydration made a good recovery. The possible aetiology of his hypernatraemia is discussed.

Hypernatraemia: balancing is challenging.

As internists we like to think of ourselves as physicians with knowledge of disturbances of the milieu intérieur. Indeed, other specialities often call us for help when they are confronted with fluid and electrolyte disorders. The unrivalled number one of your electrolyte consults will undoubtedly be hyponatraemia. For example, hyponatraemia may arise in the postoperative period due to the comb...
