作者对41例2周至12个月婴儿的67只正常耳作了同侧声反射测试,并与20个成人正常耳测试结果进行了对照。使用仪器为GS I 1723Ⅱ型中耳分析仪,但声刺激作了修改,使呈三个刺激1秒、间隔1秒的间歇刺激。所用探测音为660Hz和220Hz,刺激声为500,1000、2000和4000 Hz纯音。上述装置不产生赝象反射。测试耳均经耳镜仔细检查,排除了中耳积液。作者发现几乎所有的婴儿都必须在睡眠时才能测出满意的声导纳值,婴儿就诊后通常很疲劳,哺乳后很快入睡,对各种刺激的行为反应很少、放置探头没问题。结果:婴儿耳的85~95%在500、1000、2000 The authors performed the ipsilateral acoustic reflex test on 67 normal ears in 41 infants from 2 weeks to 12 months of age and compared them with the results of 20 normal adult ears. The instrument used was a GS I 1723 II middle ear analyzer, but the sonic stimulus was modified so that there were three stimuli intermittent stimuli at 1 second intervals of 1 second. The probing tones used were 660 Hz and 220 Hz and stimuli were pure tones of 500, 1000, 2000 and 4000 Hz. The above device does not produce artifact reflections. The test ear were carefully examined by the otoscope, ruled out the middle ear fluid. The authors found that almost all infants must be satisfied with their sound admittance at sleep. The infants are usually very tired after being treated, fall asleep soon after breastfeeding, respond very little to various stimuli, and have no problem with the probe. Results: 85-95% of infants’ ears were at 500,1000,2000
