背景和目的-基底动脉（BA）的监测是困难的，很少进行。本研究的目的是提供健康志愿者在前庭刺激期间BA的功能性经颅多普勒超声（TCD）的生理数据。方法：对26名健康志愿者（14名女性，12名男性，年龄25.1 ± 3岁）在前庭刺激期间进行BA的TCD检查。使用眼震电图（ENG）和主观眩晕量表（0 - 10分）记录眩晕。同时进行二氧化碳描记术。结果：所有受试者在前庭冲洗过程中均出现眩晕、恶心和视骨不清。平均主观眩晕持续时间为106 s（+/-65.4）;平均主观估计眩晕程度为6.7分（+/-1.5）。在所有受试者中，ENG显示左侧非灌注侧的水平眼震。14名受试者的主观眩晕被个人评为极端（分数大于或等于7），12名受试者的主观眩晕被评为低（分数
Background and purpose - Monitoring of the basilar artery (BA) is difficult and has been sparsely performed. The aim of this study was to present physiological data of functional transcranial Doppler sonagraphy (TCD) of the BA during caloric vestibular stimulation in healthy volunteers. Methods - TCD of the BA was performed in 26 healthy volunteers (14 women, 12 men, age 25.1+/-3 years) during caloric vestibular stimulation. Vertigo was documented using electronystagmography (ENG) and a subjective vertigo scale ranging from 0 to 10 points. Simultaneously, capnogpraphy was performed. Results - All subjects experienced vertigo, nausea and oszillopsia during vestibular irrigation. The average subjective vertigo was for a period of 106 s (+/-65.4); the average subjective estimated degree of vertigo was 6.7 points (+/-1.5). In all subjects, ENG demonstrated horizontal nystagm to the left non-irrigated side. In 14 subjects the subjective vertigo was rated by the individuals as extreme (point score greater than or equal to 7) and in 12 subjects as low (point score
