There has been a growing interest in the changes of pressure which occur in the middle ears of patients undergoing general anaesthesia. In this study the time course of middle ear pressure change was investigated in 38 adult E.N.T. patients scheduled for surgery under general anaesthesia with nitrous oxide. There was found to be a strong correlation between the magnitude of the post-operative middle ear pressure and the theoretical partial pressure of nitrous oxide within the middle ear cleft at the cessation of anaesthesia. The use of the mathematical model developed together with measurements of middle ear pressure taken for several minutes after intubation in any one patient allows prediction of the likely magnitude of the post-operative middle ear pressure change.
人们越来越关注全身麻醉患者中耳压力的变化。在本研究中，对38例计划在一氧化二氮全身麻醉下进行手术的成年耳鼻喉科患者的中耳压力变化时间进程进行了研究。结果发现，术后中耳压力的大小与麻醉停止时中耳裂内一氧化二氮的理论分压之间存在很强的相关性。利用所建立的数学模型，结合对任何一名患者插管后几分钟内所测的中耳压力，可以预测术后中耳压力变化的可能幅度。
