Efficacy of oral saline plus health education and autonomic nerve exercise on the treatment of postural orthostatic tachycardia syndrome in children / 中华实用儿科临床杂志

ABSTRACT

Objective To compare the efficacy of oral rehydration salts(ORS),health education and autonomic nervous activity training with health education and autonomic nervous activity training on children with postural orthostatic tachycardia syndrome (POTS).Methods Fifty-two children with POTS based on head-up test or head-up tilt test were divided into ORS treatment group and conventional treatment group.ORS treatment group included 33 children,and they received ORS and health education and autonomic nervous activity training therapy.Conventional treatment group included 19 children who received health education and autonomic nervous activity training therapy only.Telephone follow-ups were made after the therapy for 1-3 months.The contents of follow-up were the compliance of ORS treatment,the implementation of health education and POTS related symptom frequency.Results 1.The compliance of doctor's advice in ORS treatment group was better than that in the conventional treatment group.2.There was no significant difference in the symptom scores before therapy between ORS treatment group and conventional treatment group [(6 ± 3) scores in ORS treatment group vs (5 ± 3) scores in conventional treatment group,t =0.799,P ＞ 0.05].After 1 to 3 months therapy,the symptom scores were significantly lowered in both groups.The symptom scores in ORS treatment group was lower than those of the conventional treatment group[(2 ± 1) scores in ORS treatment group vs(3 ± 1)scores in conventional treatment,t =-2.189,P ＜ 0.05].3.If the therapy was determined to be effective when the symptom scores decreased by at least 2 scores,the effective rate in ORS treatment group was significantly higher than that of the conventional treatment group(78.8％ in ORS treatment group vs 42.1％ in conventional treatment group,x2 =7.169,P ＜ 0.01).Conclusions The efficacy of ORS,health education and autonomic nervous activity training therapy is better than that of the health education and autonomic nervous activity training therapy only in POTS children.
