Over the past three years the inflation-catheter technique (ICT) of controlled ventilation during general anaesthesia has proved a safe and useful method for use with laryngoscopy and other trans-oral endoscopies (most notably flexible fiberoptic bronchoscopy). The ICT allows full control of the patient's airway for the anaesthetist and exceptionally good exposure for the surgeon. In this technique ventilation of the patient is accomplished by intermittent high flow (10 ml/kg/sec) inflation of the lungs through a small (2 to 6 mm diameter) plastic orotracheal catheter. The inflation-catheter is stiffened by fixation of an intralumenal wire. Exhalation is passive around the catheter through the open airway. The Inflation Catheter Technique is readily adaptable for patients ranging from large adults to small babies by variation of catheter sizes. It can be used safely with nitrous oxide-oxygen as the ventilating gas(i.e., Bird N2O/O2 Blender) since air entrainment is not a feature. It is also readily adaptable for use with mechanical ventilation (i.e., Wolf Injectomat).
在过去三年中，全身麻醉期间用于控制通气的充气导管技术（ICT）已被证明是一种安全且有用的方法，可用于喉镜检查及其他经口内镜检查（最显著的是纤维支气管镜检查）。充气导管技术使麻醉师能够完全控制患者气道，并为外科医生提供极佳的视野。在此技术中，通过一根小口径（直径2至6毫米）的塑料口气管导管以间歇性高流量（10毫升/千克/秒）对肺部进行充气来实现患者的通气。充气导管通过管腔内金属丝固定而变硬。呼气通过开放气道在导管周围被动进行。通过改变导管尺寸，充气导管技术很容易适用于从成年大个体到小婴儿等各类患者。它可以安全地与一氧化二氮 - 氧气作为通气气体（即Bird N2O/O2混合器）配合使用，因为不存在空气夹带现象。它也很容易适用于机械通气（即Wolf Injectomat）。
