自从纤维支气管镜在牺床应用以来,在诊断上已显示出比一般金属气管镜明显优越。近年来已开始研究纤维支气管镜在病人急性呼吸衰竭时的应用。作者们认为,无论已用机械呼吸或有自主呼吸的呼吸衰竭病人,皆可用纤维支气管镜来作治疗。患者若有人工呼吸道(气管插管或气管套管),又需持续进行机械人工呼吸者,插入纤维支气管镜时需用特殊接头。为了便于同时插入纤维支气管镜和机械呼吸器,用34号气管插管和Jackson 6号气管套管。呼吸机最好用定量呼吸机,因纤维支气管镜在气道内增加了呼吸道阻力,此种呼吸机可以调节并适应纤维支气管镜所增加之阻力,而且能维持满意的潮气量。若没有 Since fiberoptic bronchoscopy has been applied in a sacrificial bed, it has been shown to be superior in diagnoses to conventional bronchoscopes. In recent years has begun to study the use of bronchoscopy in patients with acute respiratory failure. The authors believe that bronchoscopy may be used to treat patients with respiratory failure, whether mechanically ventilated or spontaneously breathing. Patients with artificial respiratory tract (tracheal intubation or tracheal tube), but also the need for continuous mechanical respiration, the need for special bronchoscope insertion connector. To facilitate simultaneous insertion of a bronchoscope and a respirator, endotracheal tube No. 34 and Jackson No. 6 endotracheal tube were used. Ventilator is best to use a quantitative ventilator, due to increased bronchoscopy in the airway airway resistance, this ventilator can adjust and adapt to the increased resistance of the fiberoptic bronchoscopy, and can maintain a satisfactory tidal volume.
