Prostacyclin and prostaglandin E2 mediate reduction of increased mean arterial pressure during cardiopulmonary bypass by aspiration of shed pulmonary venous blood

Increased mean arterial pressure during the aortic crossclamp period while on cardiopulmonary bypass was usually treated by us with hypotensive drugs. We noticed, however, that aspirating shed excess pulmonary venous blood from the open pleural cavities causes an immediate reduction in mean arterial...
