title: [A complementary clinical method to minimize air embolism during open-heart surgery].
abstract: Air from the left heart is ejected even up to several hours after cardiopulmonary bypass (CPB) despite the use of CO2. The following method is complementary in addition to surgical de-airing in order to further reduce the chance of air embolism, especially from the pulmonary veins. After re-expanding the lungs with standard bag inflation, the ventilation is restarted in consultation with the surgeon. The ventilator is set to the respiratory minute volume used before the CPB but at a respiratory frequency of 10/minutes whereas the regularly beating heart is filled from the heart lung machine. Transoesophageal echocardiography (TEE) reliably controls the effect.
