For 40 years, I have been interested in the treatment of severe hyponatremia. In 1986, I introduced the term, “Osmotic Demyelination Syndrome” to describe neurological complications of excessively rapid correction of chronic hyponatremia. In the years that followed, my co-workers and I tried to define correction rates that are fast enough to be beneficial without causing harm.
More recently, we pioneered strategies to maintain an appropriate rate of correction with the combined use of desmopressin and hypertonic saline. On this website you will find a calculator that I designed collaboratively with my son, Adam Sterns; we hope clinicians will find it helpful when managing patients with abnormal serum sodium concentrations.
