儿童血管迷走性晕厥的诱因与先兆分析

目的探讨儿童血管迷走性晕厥（VVS）诱因与先兆的特点。方法分析55例经直立倾斜试验（HUTT）诊断为VVS儿童的晕厥诱因和先兆症状，对不同性别、不同年龄段（7—11岁及12～18岁）、不同试验方式（BHUT及SNHUT）儿童的晕厥诱固和先兆的有无进行比较。结果74．55％和96．36％的VVS儿童存在晕厥诱因和先兆症状，常见诱固有长久站立（43．64％）、体位改变（20．00％）等；常见先兆症状为头晕（78．18％）、乏力（29．09％）、面色苍白（27.27％）、大汗（27．27％）、心慌（25.45％）、黑朦（23．64％）、胸闷（21．82％）、头痛（21．82％）等。晕厥诱因和先兆的有无在不同性别、年龄段、倾斜试验方式之间比较差异没有显著性（P〉0．05）。结论熟悉儿童VVS诱固和先兆特点将有助于临床诊治。

Analysis of the inducement and prodrome of children with vasovagal syncope

Objective To study the characteristics of the inducement and prodrome of children with vasovagal syncope(VVS).Methods Inducement and prodrome of 55 children with VVS were analysed and compared with each other in different gender,age groups and mode of HUTT(BHUT and SNHUT).Results 74.55% and 96.36% of children with VVS had inducement and prodrome.Familiar inducement were prolonged standing(43.64%),change of position(20.00%),and so on.Common prodromes were dizziness(78.18%),impotence(29.09%),pallor(27.27%),sweating(27.27%),palpitation(25.45%),amaurosis(23.64%),dyspnea(21.82%),headache(21.82%)and so on.There were no significant differences in different gender,age groups and mode of HUTT.Conclusions To be familiar with the inducement and prodrome will be helpful to clinical diagnosis and the therapy of children's VVS.
