摘 要:目的探讨口服补液盐(ORS)对儿童急性直立不耐受(AOI)和慢性直立不耐受(COI)的近期疗效比较。方法2008年1月至2012年8月在中南大学湘雅二医院儿童晕厥专科门诊就诊或住院的AOI与COI儿童146例。男64例,女82例;年龄4~18(11.18±2.52)岁;分AOI组(67例,主诉为晕厥)和COI组[79例,主诉为头晕(38例)、胸闷胸痛(21例)、头痛(10例)、心悸(8例)、叹气(1例)、抖动(1例)]。全部研究对象直立倾斜试验(HUTT)阳性明确诊断。在健康教育基础上予口服ORS干预,治疗14~180(39.77±31.92)d后来院复诊,询问临床症状改善情况及复查HUTT。结果1.临床主观疗效:总有效率78.8%(115/146例),有效率在AOI组与COI组比较差异无统计学意义[76.1%(51/67例)比81.0%(64/79例),x2=3.083,P〉0.05]。2.HuTT血流动力学类型:初诊AOI组与COI组类型比较差异有统计学意义(Z=-3.418,P〈0.05),2组皆以血管迷走性晕厥(VVS)中的血管抑制型为主[64.2%(43/67例)比88.6%(70/79例),x2=12.367,P〈0.05],但混合型在AOI组较COI组多见[29.9%(20/67例)比6.3%(5/79例),x2=14.134,P〈0.05],体位性心动过速综合征(POTS)2例在COI组。干预前后血流动力学类型可发生改变。3.HUTT监测客观疗效:HuTT总转阴率为39.0%(57/146例),AOI组和COI组的HUTT转阴率比较差异无统计学意义[31.3%(21/67例)比45.6%(36/79例),x2=3.083,P〉0.05]。4.HUTT阳性发作时间:HurIT阳性组分为基础直立倾斜试验(BHUT)阳性组和舌下含化硝酸甘油倾斜试验(SNHUT)阳性组。AOI及COI的阳性反应时间在治疗前BHUT组(t=-0.184)和SNHUT组(t=0.420)及治疗后BHUT组(t=0.690)和SNHUT组(t=0.145)比较差异无统计学意义(P均〉0.05);治疗前后HUTT阳性患儿(VVSObjective To explore the recent intervention effect comparison of oresol (ORS) on children with acute orthostatic intolerance(AOI) and chronic orthostatic intolerance(COI). Methods The study involved 146 children [ 64 cases were male and 82 cases were female, aged 4 - 18 years, mean ( 11.18 ± 2.52) years ] with AOI and COl in the Second Xiangya Hospital of Central South University between Jan. 2008 and Aug. 2012. The children were assigned into 2 groups. They were AOI group( n = 67, complains of syncope) and COI group [ n = 79, complains of dizziness ( 38 cases), chest tightness (21 cases), headache ( 10 cases), heart palpitations and chest pain ( 8 cases), sigh ( 1 case) ,and jitter ( 1 case) ]. All of the subjects were diagnosed as AOI or COI by head-up tilt test(HUTT) and given oresol on the basis of health education. Repeat HUTT and follow-up of 14 - 180 days [ mean (39.77 ±31.92) days] were conducted to evaluate the therapeutic effectiveness. Results 1. Subjective clinical curative effect:the total effective rate was 78. 8% (115/146 cases), and there was no significant difference in the effective rate between AOI group and COI group [ 76.1% (51/67 cases) vs 81.0% (64/79 cases) ,X2 = 3. 083, P 〉 0.05 ]. 2. The HUTT hemodynamic types : there was significant difference in the HUTT hemodynamic types between AOI group and COI group when first diagnosed ( Z = - 3. 418, P 〈 0.05 ). Vasodepressor response patients in AOI group were more than in COI group [ 64. 2% (43/67 cases) vs 88.6% (70/79 cases) ,X2 = 12. 367, P 〈 0.05 ] , and mixed response was more in AOI group than COI group [ 29.9 (20/67 cases) vs 6.3% (5/79 cases) ,X2 = 14. 134, P 〈 0.05 ]. Two patients with postural orthostatic tachycardia syndrome (POTS) belonged to COI group. The HUTT hemodynamic type could be changed after treatment. 3. The HUTT-based objective effect : total HUTT negative conversion rate was 39.0% ( 57/146 cases) ; respectively
