The impact of SD on patient mortality was also evaluated. In this large study the patients were divided into three groups of acquired hyponatremia always normal sodium and acquired hypernatremia according to their first episode of SD after arrival in the ICU. The categorization of the patients based on the first episode of SD although simple and informative we think oversimplifies a complex and common disorder in the ICU. Critically ill patients in the ICU may experience multiple episodes of SD hypernatremia or hyponatremia. A significant hypernatremic episode and its impact on final outcome could therefore easily be missed in a final analysis of patients who experienced a transient hyponatremia as the first episode of SD or vice versa. In other words .
