The technique of insufflating anesthetic gases via oro-tracheal Rusch type Foley catheter with spontaneous ventilation for microsurgery of the larynx is described. Fifteen unselected patients were used to assess the adequacy of gas exchange with this technique. Arterial blood gas analysis was carried out 5 minutes and 25 minutes after induction of anesthesia. The results at 25 minutes indicate adequate gas exchange. There was a significant increase in the PaO2 at 25 minutes but the decrease in PaCO2 at 25 minutes was insignificant. The technique also provided very satisfactory conditions for surgery with only minimal risk of gross tracheal soiling. No dysrhythmias were encountered and there was hemodynamic stability in all cases.
本文描述了一种在喉显微手术中，经口气管插入Rusch型Foley导管并进行自主通气来吹入麻醉气体的技术。选取了15例未经筛选的患者，以评估该技术下气体交换的充分性。在麻醉诱导后5分钟和25分钟进行动脉血气分析。25分钟时的结果表明气体交换充分。25分钟时动脉血氧分压（PaO2）显著升高，但动脉血二氧化碳分压（PaCO2）在25分钟时的降低不显著。该技术还为手术提供了非常令人满意的条件，气管严重污染的风险极小。未出现心律失常，所有病例均血流动力学稳定。
