Abstract:

Objective　To evaluate the safety and feasibility of the application of bronchial occluder in the right lobe one-lung ventilation in thoracic surgery.　Methods　From July 2012 to August 2013, 36 consecutive patients who need the right lobe one-lung ventilation in thoracic surgery were enrolled and were randomly divided into two groups: group A and group B, 18 cases in each group. The traditional double lumen bronchial method was used in group A and the bronchial occluder was used in group B intubation time. Changes of vital signsbefore and after intubation,the qualityof lung collapse during operation, pH, arterial partial pressure of CO2, partial pressure of oxygen and airway pressure Paw were recorded 20 min, 40 min,and 60 min after intubation or one-lung ventilation. The number of patients with hypoxia in the operation and postoperative complications in each group were also recorded.　Results　The airway pressure in group B was significantly lower than that in group A, and the number of patients with postoperative complications such as hypoxia and postoperative hoarseness was significantly lower (P<0.05).　Conclusion　Bronchialoccluder method could solve intraoperative blood oxygen desaturation caused by the double lumen endobronchial malalignment, and airway irritation was mild. Consequently，it is a safe and effective method for single lung ventilation in the right lobe one-lung ventilation in thoracic surgery.
