Nystagmic responses to traditional 40-sec, 30 degrees C water calorics were recorded and compared to those obtained with the Brookler-Grams closed-loop irrigator using 30 degrees C, 40-, 50-, and 60-sec irrigations. Significant differences were noted between the responses to the water irrigator and the 40- and 50-sec closed-loop irrigations. The 60-sec closed-loop irrigation produced responses that were equivalent to the responses obtained with the water irrigation in slow component velocity, amplitude, frequency, latency, and duration. The 30 degrees C 60-sec closed-loop irrigation is an acceptable stimulus in electronystagmographic caloric testing.
记录了对传统40秒、30摄氏度水试验的眼球震颤反应，并将其与使用30摄氏度、40秒、50秒和60秒冲洗的布鲁克勒-格拉姆斯闭环冲洗器获得的反应进行比较。在对水冲洗器的反应与40秒和50秒闭环冲洗的反应之间发现了显著差异。60秒闭环冲洗产生的反应在慢相速度、幅度、频率、潜伏期和持续时间方面与水冲洗获得的反应相当。30摄氏度60秒闭环冲洗是眼震电图冷热试验中一种可接受的刺激。
