衰老对眩晕患者冷热试验最大慢相角速度结果的影响

摘要：目的分析不同年龄组眩晕患者冷热试验的最大慢相角速度（maxSPV）的平均值有无差异，探讨衰老对眩晕患者冷热试验结果的影响。方法前瞻性收集2015年3月—2018年11月就诊北京老年医院眩晕门诊的228例患者，年龄14~88岁。所有患者分成3组，60岁以下为A组，60~79岁为B组，80岁以上为C组，应用SPSS 17.0统计软件分析3组患者冷热试验的maxSPV的平均值有无差异。结果3组患者之间比较差异具有统计学意义（F=3.203，P=0.042），A组与B组之间差异无统计学意义（P=0.567），C组与A组、B组差异具有统计学意义（P=0.037，P=0.013）。结论只有在高龄患者中，冷热试验maxSPV的平均值才出现明显下降，提示衰老可能影响眩晕患者的冷热试验。

Effect of aging on the results of maximum slow phase velocity in the caloric test of patients with vertigo

ObjectiveTo explore the effect of aging on the parameters of the caloric test via analyzing the difference of the mean values of maximum slow phase velocity (maxSPV) in patients with vertigo in different age groups.MethodsTwo hundred and twenty eight patients, aged from 14 to 88 years old, who were admitted to the vertigo clinic of Beijing Geriatric Hospital from March 2015 to Nov 2018, were prospectively collected. All patients were divided into 3 groups: group A (below 60 years), group B (60 to 79 years), and group C (over 80 years). The mean values of maxSPV in the caloric test among the three groups were analyzed by SPSS 17.0 statistical software.ResultsThe differences of the mean values of maxSPV among the three groups were statistically significant (F=3.203, P=0.042). There was no significant difference between group A and group B (P=0.567), while the difference between group C and group A and that between group B and group C were both statistically significant (P=0.037, P=0.013).ConclusionThe mean value of maxSPV in the caloric test shows a significant decline only in elderly patients, which indicates that aging may affect the caloric test in patients with vertigo.
