不明原因晕厥相关性躯体意外伤害

Unexplained syncope-related body traumatic injury

目的探讨不明原因晕厥相关性躯体意外伤害情况。方法对不明原因晕厥患者（n=351）详细询问病史，包括晕厥发作时躯体意外伤害事件的发生情况，并行倾斜试验（HUTT）检查明确诊断。结果①31例（8．8％）患者有晕厥相关性躯体意外伤害，HUTT阳性患者中19例（11．5％）存在晕厥相关性躯体意外伤害；②晕厥致躯体意外伤害大多较轻，少数患者会发生严重伤害；③发生晕厥相关性躯体意外伤害者男性较多，年龄段以9～13岁居多；④躯体意外伤害患者HUTT反应类型以血管抑制型为主。混合型次之，心脏抑制型最少。结论晕厥相关性躯体意外伤害事件的发生是随机的，大部分患者伤害较轻，个别患者会发生严重意外伤害。强调对不明原因晕厥患者重视HUTT检查。对确诊的血管迷走性晕厥（VVS）患者实施早期干预，将躯体意外伤害事件的发生降至最低限度。

Objective To explore the unexplained syncope - related body traumatic injuries. Methods Unexplained syncope patients＇ histories were carefully inquired including body traumatic injuries during syncope, and head - up tilt table test （ HUTT） was performed in these patients. Results 31 out of 351 patients （ 8.8% ） had syncope -related body traumatic injuries, and 19 cases with positive HUTT had syncope - related body traumatic injuries and accounted for 11.5% of all positive patients. Most of the injuries caused by faint were minor, and serious body injuries happened on a few patients. Patients with syncope- related injuries showed a higher trend of male and age was more between 9 and 13 years old. Vasodepressive response to the HUTT was the commonest, then mixed response, and cardioinhibitory response was the rarest. Conclusions Syncope-related body traumatic injuries happens at random. Most of the injuries are minor, but sometimes serious body injuries may happen. The examination of HUTT in the patients with vasovagal syncope and early medical intervention to them may help reduce syncope -related body traumatic injuries to the least degree.
