Clinical study on the effect of different position combined with tracheal catheter oblique plane in the blind insertion of bronchial blocker on one-lung ventilation

Abstract

Objective To investigate the effect of different position combined with guidance of tracheal catheter oblique plane opening on the blind insertion of bronchial blocker. Methods 30 children and 30 adults scheduled for thoracotomy were chosen from our hospital, both the children group and adult group were randomly subdivided into three groups. The patients in Group A were intubated in the supine position on the random catheter oblique plane, and then were inserted the bronchial blocker blindly; the patients in Group B were intubated in the supine position on the catheter oblique plane toward the sealing side, and then were inserted the bronchial blocker (both Group A and Group B were placed in the lateral position after the insertion of bronchial blocker); the patients in Group C were intubated in the supine position on the catheter oblique plane toward the sealing side, were placed in the lateral position, and then were inserted the bronchial blocker. The one-time success rate of bronchial blocker insertion, the total time of occlusion, the incidence of hypoxemia during the insertion, the incidence of postoperative airway edema in the three groups were recorded. Results In the children group, the one-time success rate of bronchial blocker insertion in Group C was significantly higher than those in Group A and Group B (P 0.05). Conclusion By adjusting the position and using guidance of tracheal catheter oblique plane opening, the success rate and the rate of insertion can be effectively improved, and the complications of intubation can be reduced, which is worthy of clinical popularization.
