Application of Bronchial Blocker in Minimally Invasive Cardiac Surgery

Bronchial Blocker in Blocking the Right Middle Lower Lobe Versus Double-Lumen Endotracheal Tube for One-Lung Ventilation in Minimally Invasive Cardiac Surgery

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.

Inclusion Criteria:

• ASA II-III
• BMI 18-31
• elective minimally invasive cardiac surgery by right thoracotomy

Exclusion Criteria:

• asthma
