Two cases of middle-ear injury, due to sharp fluctuations of intratympanic pressure as a result of general anaesthesia with nitrous oxide are presented. A study is reported indicating that the degree of these fluctuations is a function of the concentration of nitrous oxide. In order to reduce the risk of middle-ear injury due to nitrous oxide anaesthesia, it is suggested that the lowest concentration feasible should be used where there is a history of previous ear surgery.
本文报告了两例因一氧化二氮全身麻醉导致鼓室内压力急剧波动而引起的中耳损伤病例。一项研究表明，这些波动的程度是一氧化二氮浓度的函数。为降低一氧化二氮麻醉引起中耳损伤的风险，建议在有既往耳部手术史的情况下，应使用可行的最低浓度。
