Application of Bronchial Blocker in Minimally Invasive Cardiac Surgery

Not Applicable

• Conditions: Minimally Invasive Cardiac Surgery
• Interventions: Device: bronchial blocker for BB group; Device: double lumen tube for DLT group

• Registration Number: NCT03505242
• Lead Sponsor: Shanghai Zhongshan Hospital

Brief Summary

Both left single lung ventilation by left double lumen tube and bilateral ventilation with selective blockage of right middle lower lobe by bronchial blocker can provide suitable surgical field for minimally invasive cardiac surgery. The current study was designed to compare the impact of these two different methods on oxygenation, degree of pulmonary collapse and postoperative complications.
