[ENG in young children--a contribution on examination problems. IInd part: rotation test (author's transl)]

This study reports the electronystagmographic results of 60 young children (3-6 years old) without any history of ear disease. Distribution into the groups "without sedation" and "with sedation" was done following a statistical key. The revolving chair was stopped after rotation at an angular velocity of 108 degrees/sec. Sedation was achieved by intramuscular injection of Valium. The statistical analysis of the various parameters is restricted to the postrotatory nystagmus I. Neither during the whole duration of the postrotatory nystagmus I nor during the cumulatory phase any significant difference in the total amplitude or number of beats could be observed. The only statistically significant difference was found in the maximal angular velocity; the reduction was 15+/-9% compared to the non sedated group. These results indicate that Valium can be used for sedation in nystagmographic examination.
