It is known that nitrous oxide anaesthesia results in an increase of the middle ear pressure. The aim of this project was to find out, if an increase of the middle ear pressure due to high concentration of nitrous oxide could lead to evacuation of the seromucoid secretion through the Eustachian tube. In 37 children (64 ears) scheduled for myringotomy, tympanograms were performed immediately before and during anaesthesia, the middle ear fluid was confirmed by myringotomy and, if any, sucked out. Both the comparison of the tympanograms prior and during the anaesthesia and the results of myringotomy led to a conclusion, that, in general, nitrous oxide anaesthesia induces no evacuation of middle ear fluid via the Eustachian tube.
已知氧化亚氮麻醉会导致中耳压力升高。本项目的目的是查明，高浓度氧化亚氮引起的中耳压力升高是否会导致浆液黏液性分泌物通过咽鼓管排出。在37例计划行鼓膜切开术的儿童（64耳）中，在麻醉前及麻醉期间立即进行鼓室图检查，通过鼓膜切开术确认中耳积液，如有积液则吸出。麻醉前和麻醉期间鼓室图的比较以及鼓膜切开术的结果均得出结论，一般来说，氧化亚氮麻醉不会通过咽鼓管促使中耳积液排出。
