Objective To explore the changes in serum and urine electrolytes of children with neurally mediated syncope (NMS) after oral rehydration salts (ORS) [Ⅰ] treatment.

Methods The study group included 135 patients [60 male 75 female, aged 4-16 years, average (10.20±2.68) years old] unexplained prodromal symptoms our hospital between May 2014 April 2015.The underwent head-up tilt test (HUTT), completed 24-hour electrolytes, different hemodynamic type HUTT were compared.Positive treated health education ORS[Ⅰ], while negative received education.Then 21-154(42.63±27.71) days later, returned to hospital, for inquiry symptom improvement, review HUTT, electrolytes.

Results (1)The total effective rate ORS[Ⅰ] treatment was 62.96% (17/27 cases), conversion 48.15% (13/27 cases). (2)There no significant difference or volume positive during first visit (all P>0.05). (3)In return visit, calcium [(2.30±0.10) mmol/L vs (2.20±0.09) mmol/L, t=2.72, P 0.05). (4)24-hour sodium [(159.06±72.76) mmol/24 h (118.97±52.75) h, t=2.712, (5)There vasovagal postural orthostatic tachycardia syndrome visit(all P>0.05).

Conclusions ORS[Ⅰ] can obviously increase sodium, chloride NMS.ORS[Ⅰ] is an therapy NMS.
