摘要： 目的探讨左侧双腔支气管导管(DLT)型号与左主支气管内径的相关性。方法随机抽取胸外科手术需行左侧DLT插管的成年病人100例,所有病人术前均行胸部螺旋CT扫描,利用三维图像重建技术测定病人隆突水平与左主支气管纵轴垂直平面的左主支气管内径值,根据左主支气管内径值插入左DLT,以纤维支气管镜定位或引导插管、采用“气泡溢出法”和“主支气管套囊压力测定法”判断DLT型号的合适性和插管的准确性。结果合适的左DLT型号与左主支气管内径有相关性,相关系数为0.7346。结论临床上,可根据左主支气管内径测量值指导选择左DLT。

Abstract: Objective To investigate the association of the left double-lumen endobronchial tube (DLT) and the inner diameter of the left main bronchus. Methods Totally 100 adult patients who required intubation of a left-sided DLT during anesthesia for elective thoracic surgery were randomly enrolled in this study.All the participants underwent a preoperative chest CT scan by a spiral CT scanner.The diameters of the trachea and left main bronchus were measured with three-dimensional image reconstruction technique.All the measurements were performed using the electronic calipers of the spiral CT scanner and the left-sided DLT (Portex SIMS,USA) of the sizes 41Fr,39Fr,37Fr,and 35Fr were selected,being predicted according to the inner diameter of the left main bronchus.The placement of DLT was performed after anesthesia induction,and a DLT of a smaller size was selected if the bronchial end of the DLT failed to enter the left main bronchus after two attempts.The trachea and left main bronchus were examined for injury and other complications with postoperative fibreoptic bronchoscopy (FOB). Results All the 100 patients were intubated with DLT of appropriate sizes and satisfactory lung isolation was achieved.Postoperative complications of the trachea and bronchus were observed in none of the patients with FOB examination.The appropriate size of DLT is correlated with the left main bronchial diameter (correlation coefficient r=0.7346). Conclusion Clinically,the size of DLT can be determined in accordance with the inner diameter of the left main bronchea.
