Summary

To compare the effectiveness of unilateral pulmonary collapse (right lung) to bilateral pulmonary collapse for cardiac de-airing in open left-sided heart surgery.

Detailed description

Effective removal of air from the heart before termination of cardiopulmonary bypass (CPB) is vital in open left heart surgery. Bilateral collapse of the lungs during cardiopulmonary bypass decreases the duration of the de-airing procedure, decreases residual air emboli monitored on Trans-esophageal Echocardiography (TEE) and decreases gaseous cerebral microemboli (MES) monitored by Trans-cranial Echo-Doppler (TCD) when compared to expanded lungs during (CPB). Induced pulmonary collapse by opening of the pleura and disconnection of the patient from the ventilator during CPB decreases the amount of air that can enter the pulmonary veins. Not all surgeons wish to induce lung collapse from fraught that it might lead to pulmonary ischemia or infection. It is unknown whether collapse of only the right lung is as effective as collapse of both lungs.

Conditions

• Brain Ischemia
• Reduction of Cerebral Air Emboli

Interventions

Type	Name	Description
PROCEDURE	Bilateral Open Pleurae	Both pleurae are opened Right pulmonary vein drainage
PROCEDURE	Right Pleura Open	Right pleura open Left ventricular apical drainage
