入选标准
- •patients undergoing thoracic surgery under left lower decubitus position, using left sided double lumen tube
- •patient's left main bronchus size adequate for 35Fr, 37 Fr, 39 Fr double lumen tube
排除标准
- •dislocation or great movement of double lumen tube depth
研究组 & 干预措施
39 Fr double lumen group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
干预措施: 39 Fr double lumen tube group (Procedure)
37 Fr double lumen group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
干预措施: 37 Fr double lumen tube group (Procedure)
35 Fr double lumen tube group
patients are assigned to 35 Fr, 37 Fr, 39 Fr double lumen tube group according to their left main bronchus diameter measured by preoperative chest CT, to minimize difference between main bronchus diameter and bronchial tip diameter of double lumen tube
干预措施: 35 Fr double lumen tube group (Procedure)
