Minimally Invasive Cardiac Surgery
Conditions
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.
Interventions
Using bronchial blocker to block right middle lower lobe during surgery.
Using double lumen tube to achieve single lung ventilation during surgery.
