ABSTRACT

Objective To evaluate the efficacy of Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management in patients undergoing upper mediastinal tumor resection. Methods Twenty-two ASA Ⅱ or Ⅲ patients, aged 24-66 yr, weighing 48-78 kg, scheduled for elective resection of upper mediastinal tumor, were randomly divided into 2 groups (n=11 each)double-lumen tube group(groupⅠ) and Coopdech bronchial blocker combined with a strengthened single-lumen tube group(group Ⅱ).One-lung ventilation was achieved with a double-lumen tube in groupⅠ. The Coopdech bronchial blocker combined with a strengthened single-lumen tube was used for airway management and the Coopdech bronchial blocker was used for lung isolation when one-lung ventilation was required in group Ⅱ. The fiberoptic bronchoscope was used to assist endotracheal tube positioning in both groups. The intubation time, positioning time, the number of patients required for tube displacement, the number of fiberoptic bronchoscopy, increase in airway peak pressure, degree of lung collapse, postoperative sore throat and hoarseness, and the number of patients needing ventilator-assisted ventilation were recorded. Results The intubation time was significantly shorter, the number of patients required for tube displacement was significantly smaller,and the rate of increase in airway peak pressure and incidences ofpostoperative sore throat and hoarseness were significantly lower in group Ⅱ than in group Ⅰ (P＜0.05 or0.01). Conclusion The efficacy of the Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management is better in patients undergoing upper mediastinal tumor resection than the double-lumen tube.
