A number of intra and postoperative accidents in close cavity surgery when using nitrous oxide have been reported. In order to check the influence of nitrous oxide anesthesia in tympanic surgery, 38 patients were operated on by the usual techniques in middle ear surgery. Half the patients received continuous nitrous oxide inhalation throughout the procedure while, in the remaining cases, the anesthetic gas was suspended 30 minutes before applying the tympanic graft. Audiological differences in both groups, as controlled at 6 and 12 months, were negligible.
已有报道称，在使用一氧化二氮进行体腔手术时会发生一些术中及术后意外。为了检查一氧化二氮麻醉对鼓膜手术的影响，38例患者接受了中耳手术的常规技术操作。一半患者在整个手术过程中持续吸入一氧化二氮，而在其余病例中，在应用鼓膜移植物前30分钟停止使用麻醉气体。两组在6个月和12个月时进行对照的听力学差异可忽略不计。
