Bilateral sequential lung transplantation is now an accepted therapy for patients with end-stage cystic fibrosis. In our experience, the use of a standard double-lumen endotracheal tube to establish one-lung ventilation during bilateral lung transplantation has been associated with difficulty in clearing the airway of the thick, tenacious secretions characteristically seen in these patients. Intraoperatively, retained secretions have resulted in inadequate ventilation with subsequent hypercarbia, hypoxia, and the need for cardiopulmonary bypass support. We therefore changed our airway management to a single-lumen endotracheal tube combined with a bronchial blocker to establish one-lung ventilation during bilateral lung transplantation. The lumen of a single-lumen tube accommodates larger suction catheters and an adult bronchoscope, which has a larger suction port. We have used this technique in our last five transplantations, finding easier clearing of airway secretions along with markedly improved ventilation compared with management with a double-lumen tube. We recommend this technique of airway management when performing a bilateral single-lung transplantation for end-stage cystic fibrosis.
双侧序贯肺移植现已成为终末期囊性纤维化患者公认的治疗方法。根据我们的经验,在双侧肺移植过程中使用标准双腔气管导管建立单肺通气时,对于清除这些患者特有的浓稠、黏稠分泌物存在困难。术中,残留的分泌物导致通气不足,继而出现高碳酸血症、低氧血症,并需要体外循环支持。因此,我们在双侧肺移植过程中将气道管理改为使用单腔气管导管联合支气管封堵器建立单肺通气。单腔导管的管腔可容纳更大的吸引导管和具有更大吸引端口的成人支气管镜。我们在最近的五次移植中采用了这种技术,发现与使用双腔导管管理相比,气道分泌物清除更容易,通气也明显改善。对于终末期囊性纤维化患者进行双侧单肺移植时,我们推荐这种气道管理技术。
