摘要
目的 分析直立倾斜试验阳性与不明原因晕厥患儿临床特征的关系。方法 对 47例不明原因晕厥患儿 ,根据其直立倾斜试验的结果分为二组 :直立倾斜试验阳性组和阴性组 ,将其临床特征进行对比分析研究 ,并对其各个临床特征与直立倾斜试验的结果进行Logistic回归分析。 结果 不明原因晕厥患儿的性别、年龄、有无晕厥诱因及有无晕厥先兆对直立倾斜试验的结果有影响 ,根据Logistic回归分析 ,对直立倾斜试验结果有显著影响的因素依次为晕厥诱因、晕厥先兆和年龄。结论 对于发生于青春期女孩不明原因的晕厥 ,而患儿又有较明确的晕厥诱因和晕厥先兆者 ,其直立倾斜试验阳性的可能性较大 ,临床可诊断为血管迷走性晕厥。
Objective To analyze the relationship between the clinical characteristics of unexplained syncope of children and positive response to head-up tilt test (HUT). Methods The clinical data of 47 patients with unexplained syncope were divided into two groups according to their outcomes of HUT: positive response group and negative response group. The authors compared their clinical data, and analyzed them with the logistic regression.Results The incidence of positive responses with HUT was higher in girls than in boys (8/22 vs 10/7,P<0 05), and compared with fainted children under 12 years, 12 to 16 years old adolescent with unexplained syncope had higher positive outcomes with HUT (30% vs 72 9%,P<0 05). Compared with fainted children with negative response in HUT, children with positive response in HUT often occurred in some special circumstances, for example, prolonged standing, anxiety and fright, morning exercise, etc, and they often had prodrome such as pallor, lightheadedness, nausea, etc (28/30 vs 8/17,P<0 5). But the number of syncopal spells or duration syncopal spells did not relate to the positive responses in head-up tilt tests. In logistic regression analysis, there were 3 factors which influenced outcomes of HUT significantly: cause of syncope, prodrome of syncope and age (P<005; RR=329434, 177281, 27842, respectively). Conclusion\ If a pubertal girl with unexplained syncope has clear cause of syncope and prodromes, she is likely to have positive response to HUT. Therefore, it is likely for her to be clinically considered as having vasovagal syncope.
