A case of Osmotic demyelination syndrome despite normal rate of Sodium correction with good recovery

The Osmotic demyelination syndrome (ODS) primarily occurs with rapid correction of severe hyponatraemia that has been present for more than two or three days. Some patients are, however at risk and can develop ODS at higher sodium concentration and lower rates of correction. A case of Osmotic demyelination Syndrome which developed despite an ‘optimal’ rate of correction of serum Sodium with good clinical outcome is described. The risk factors that contribute to development of ODS and strategies to prevent this complication are discussed, along with recommendations on how to manage this condition in hospital inpatients.
