防晕帽各组成部分对前庭自主神经反应作用的分析

目的分析防晕帽各组成部分对前庭自主神经反应的作用。方法将90名年轻健康飞行人员随机分为三组：A组为对照组，戴空白帽，将防晕帽中磁片、风扇及负离子发生器去掉者；B组为戴去掉风扇及负离子发生器帽子组；C组为戴防晕帽组。三组均在戴帽15min后进行科里奥利加速度试验，受试者出现I。前庭自主神经反应时停止转椅并观察20min，依照前庭自主神经反应程度进行分度，对受试时间和前庭自主神经反应程度进行比较。结果三组科里奥利加速度试验持续时间分别为（349．43±31．60）s、（366．23±32．62）s、（385．17±35．54）s，差异均有统计学意义（P〈0．05），前庭自主神经反应程度发生率差异亦有统计学意义（P〈0．05）。结论防晕帽中穴位磁片、风扇和负离子发生器的综合作用可有效降低前庭自主神经的反应程度，为运动病的防控提供了新的思路和措施。

Effect of anti-sick hat ingredients on vestibular autonomic nerve reaction

Objective To analyze the effect of anti-sick hat ingredients on vestibular autonomic nerve reaction. Methods Ninety male young and healthy pilots were randomly divided into group A （control group）, group B and group C, 30 in each group. Pilots in group A wore a hat without magnetic disk, ventilator and negative ion generator, pilots in group B wore a hat with magnetic disk but without ventilator and negative ion generator, and those in group C wore an anti-sick hat. Each pilot was asked to wear a corresponding hat 10 minutes before Coriolis acceleration test and seated in a rotary chair until he requested termination because of near-vomiting. The pilots were observed for 20 minutes when they presented with l~vestibular autonomic nerve reaction. Vestibular autonomic nerve reaction was graded. Degree of vestibular autonomic reaction and exposure time to Coriolis acceleration test were compared. Results The exposure time to Coriolis acceleration test was （349.43 ± 31.60）s, （366.23 ± 32.62）s, and （385.17 ± 35.54）s respectively in 3 groups（P〈0.05）. The incidence of vestibular autonomic reaction was significantly different in 3 groups（P〈0.05）. Conclusion Anti-sick hat with magnetic disk, ventilator and negative ion generator can effectively decrease vestibular autonomic nerve reaction in pilots, thus providing some new ideas and measures for the prevention and control of motion sickness.
