Function pre and post cardiopulmonary bypass surgery

Fuzioki Yamamura

Pulmonary dysfunction is a known complication after cardiac surgery using cardiopulmonary bypass, ranging from sub-clinical functional changes to prolonged postoperative ventilation, acute lung injury and acute respiratory distress syndrome. Whether human pulmonary arterial function is compromised is unknown. The aim of the present study was to compare the structure and function of isolated and cannulated human pulmonary arteries obtained from lung biopsies after the chest was opened (precardiopulmonary bypass) to those obtained at the end of cardiopulmonary bypass (post-cardiopulmonary bypass) from patients undergoing coronary artery bypass graft surgery.
