Abstract:
Objective:To explore the comparative study of video laryngoscopy combined with bronchial blocker and video laryngoscopy combined with double-lumen tube in the teaching of endotracheal intubation in thoracic surgery in the standardized residency training of anesthesia.Methods:The trainees of the standardized residency training were randomly divided into control group and experimental group for clinical teaching, with 25 ones in each group. The experimental group was treated with visual laryngoscopy combined with bronchial blocker, while the control group was treated with visual laryngoscopy combined with double-lumen tube group. The intubation time, intubation success rate, positioning time, hemodynamic changes, and complication incidence during intubation, as well as student assessment results were recorded. GraphPad Prism 6.0 was used for t test and Chi-square test. Results:The time of endotracheal intubation [(95.3±10.1) vs. (137.5±13.5)] and positioning time [(100.8±11.7) vs. (155.4±15.3)] in the experimental group were both shorter than those of the control group ( P< 0.001), the hemodynamic changes in patients with immediate intubation were smaller ( P<0.001), the success rate of intubation was higher (92% vs. 68%) ( P<0.001), the complication incidence was lower ( P<0.001) and the students' performance was higher ( P<0.001). Conclusion:In the anesthesia teaching of thoracic surgery, bronchial blocker can reduce the time of endotracheal intubation, lower the hemodynamic changes during intubation, cut down the incidence of complications, improve the success rate of endotracheal intubation and enhance the confidence of students.
