Air, saline and a mixture of nitrous oxide and oxygen were used to inflate the cuffs of tracheal tubes inserted into three groups of patients, during nitrous oxide anaesthesia. Large increases in intracuff pressure were seen in the air group, but no morbidity resulted. The intracuff pressure decreased in the gas mix group and leaks occurred in some patients. Initial adjustment of cuff pressure was more difficult in the saline group but the pressure remained stable thereafter.
在氧化亚氮麻醉期间，使用空气、盐水以及氧化亚氮和氧气的混合气体给三组患者插入的气管导管气囊充气。空气组患者气囊内压力大幅升高，但未导致任何不良后果。气体混合组气囊内压力降低，部分患者出现漏气情况。盐水组气囊压力的初始调整更为困难，但此后压力保持稳定。
