Thirty patients with a laryngeal polyp or other tumour, were operated on under the microscope. During the operation, which lasted from 10 to 30 minutes, ventilation was ensured by injection of oxygen at 3 to 4 atmospheric pressures through a naso-tracheal catheter. Anaesthesia was obtained by an association of propanidide, small doses of analgesic and succinycholine, constant rate syringes were used for maintenance of narcosis and curarisation. In 23 patients, blood gases were analysed at various stages of the operation permitting one to assess the quality of the ventilation carried out. In a few patients, it was also possible to record pressure curves in the trachea. The results were excellent, both concerning the quality of the ventilation and that of the anaesthesia together with the operative conditions. After recalling the main characteristics of this mode of ventilation which uses Venturi's principle, the authors expose the other methods which are variants compared with their technique of use of this procedure for laryngeal micro-surgery.
30例患有喉息肉或其他肿瘤的患者在显微镜下接受了手术。手术持续10至30分钟，在此期间，通过经鼻气管导管以3至4个大气压注入氧气来确保通气。通过丙泮尼地、小剂量镇痛药和琥珀酰胆碱联合使用来实现麻醉，使用恒速注射器维持麻醉和肌松。23例患者在手术的不同阶段进行了血气分析，从而能够评估通气质量。在少数患者中，还记录了气管内的压力曲线。通气质量、麻醉质量以及手术条件方面的结果都非常出色。在回顾了这种利用文丘里原理的通气方式的主要特点之后，作者介绍了与他们在喉显微手术中使用该方法的技术相比的其他变体方法。
