Comparison of Two Methods With a Left-Sided Double-Lumen Tube for Endobronchial Intubation
Objective To compare the success rates of two methods for endobronchial intubation:the left-sided double-lumen tube(DLT)rotated 90° counter-clockwise with the patient head at the mid positon and the tube rotated 180°counter-clockwise with the patient head turned to the right.Methods Six hundred and forty-eight patients were enrolled in this study,who were to undergo elective thoracic surgery by left-sided DLT intuba-tion in the Peking Union Medical College Hospital from December 2021 to June 2022.They were randomized into a 90° group and a 180° group,with 324 patients in each group.In the 90° group,with the patient head kept at the mid position,the left-sided DLT was advanced until the bronchial cuff passed the vocal cords and then rotated 90° counter-clockwise.In the 180°group,with the left mandible angle of each patient in the straight line with the ster-num,the tube was advanced until the bronchial cuff passed the vocal cords and then rotated 180° counter-clock-wise.The intubation success rate and the intubation-related complications such as carina mucosal injuries were com-pared between the two groups.Results The 648 patients included 336 males and 312 females,with the age ran-ging from 39.0 to 75.0 years old and the average age of(54.6±9.0)years old.The success rate of first intubation was 80.3% in the 90°group and 75.0% in the 180°group,which showed no significant difference(P =0.109).The success rate of second intubation was higher in the 180°group than in the 90°group(P<0.001).The rate of carina mucosal injuries was 23.8% in the 90° group and 25.6% in the 180° group,which showed no significant difference(P =0.585).Conclusions Compared with the conventional method(90°),the intubation of the left-sided DLT rotated 180° counter-clockwise with the patient head turned to the right cannot improve the success rate of the first intubation.However,it could improve the success rate of reintubation as a remedy.
