The research progress of oral rehydration salts treating neurally mediated syncope in children

Neurally mediated syncope (NMS) is the most common children unexplained syncope. Oral rehydration salts is the basis for the treatment of NMS. Oral rehydration salts can increase the extracellular fluid and blood volume, change the redistribution of blood, avoid the emptying effect caused by inadequate left ventricular filling volume when position changes suddenly, prevent increased vagus nerve activity induced syncope, can obviously increase the NMS children′s ability of orthostatic intolerance. Increase water salt intake can be incorporated into the behavior training of the NMS children′s daily life, and it can reduce the occurrence rate of NMS children, and improve the quality of life.
