Unilateral Ventilation on Cardiopulmonary Bypass During Cardiac Surgery

Unilateral Ventilation on Cardiopulmonary Bypass During Cardiac Surgery in Patients at Increased Risk for Severe Postoperative Pulmonary Complications

This study investigates if single lung ventilation on cardiopulmonary bypass can mitigate postoperative lung water accumulation determined by lung ultrasound in the ventilated lung as compared to the non-ventilated lung in patients at high-risk for developing severe pulmonary complications after cardiac surgery.

Inclusion Criteria:

• Patients at increased risk for postoperative pulmonary complications
• Major elective cardiac surgery
• Prolonged duration of cardiopulmonary bypass
• Patients older than 65 years of age
• Informed consent

Exclusion Criteria:

• Emergency
• Urgent procedures
• Patients with implanted pacemakers
• Patients with internal cardioverter/defibrillators
• Decompensated cardiac disease
• Pulmonary disease
• Recent pneumonia
• Need for temporary perioperative mechanical support
• Patients not willing to participate
• Treatment with inhaled nitric oxide
