Volumetric evaluation of lost of pulmonary aeration and edema after coronary artery bypass surgery using computed tomography


Lost of pulmonary aeration, which is caracterazed by development of atelectasia and parcially colapsed areas and pulmonary edema, represent high incidence complications in cardiac surgery post-operative period, being responsable for a longer time in mecanic ventilation, a greater incidence of respiratory infection, mortality and an increase in custs. As described by Puybasset and col. is possible to quantify the lost of aeration and pulmonary edema caused by the anestetic-surgical procedure using helicoidal computed tomography. The purpose of this study is to quantify the lost of aeration and pulmonary edema after cardiac surgery comparing with the pre-operative values,as well as the alterations in respiratory exchanges.
