Hyponatremia in Postoperative Patients

Sodium as a major extra cellular ion is of primary importance is reflecting changes of water and electrolytes status in the body [1]. Postoperative hyponatremia and its relative complications can occur after any surgical procedure [2], particularly in elderly patients. The early symptoms can be mild which if not recognized on time, can progress to severe neurological manifestations and can even prove fatal to patients. The early warning is most of the time taken as normal post-operative sequelae resulting in increasing morbidity and mortality in patients with hyponatremia. The treatment is simple and in most cases, the early complications can be reversed by infusing sodium containing solutions [3].
