改良型左双腔支气管导管的设计与临床应用

摘要

Objective To reduce the dififculties in intraoperative localization and displacement rate of DLT (Double-Lumen Endotracheal Tube). Methods Structural improvements were made on the L-DLT (L-DLT) so as to make it more suitable for clinical application. Results The improved L-DLT was superior to the original one in the intraoperative localization and displacement rate. Conclusion The improved L-DLT is securely-operated and simply-positioned in pulmonary isolation surgeries, which is more suitable for clinical application.%目的降低双腔支气管导管插管定位难度和降低术中导管移位率。方法通过对左Robertshaw双腔支气管导管结构的改良，使其更适合临床应用。结果使用改良型左双腔支气管导管，在插管定位及术中导管移位率明显优于左Robertshaw双腔支气管导管。结论改良型左双腔支气管导管在肺隔离术中应用安全、定位简单且术中导管移位率低，适用于临床。
