We reviewed medical record of patients who underwent CBP. We enumerate patients who developed pleural effusion and the indication of cardiac surgery. We analyzed the duration of every cardiopulmonary bypass, the characteristic and time to onset of pleural effusions.Results:Among 50 patients included in the study, only 28 (56%) developed a pleural effusion. The most of these effusions occurred 15 days post surgery. Pleural fluid was hemorrhagic and fluid analysis showed an exudate in all cases. The volume of effusion was under 120 ml in 80% of patient and about 600 ml in 20% of cases. Coronary artery bypass grafting (CAPG) (71%) and valvular replacement (VR) (22%) were the most common indications for cardiac surgery. The pleural effusion occurs in 40% of patients how underwent CAPG and in 14% of patient how benefit of VR. The mean duration of CBP in patients who developed pleural effusion was 99,11min [50 min, 163 min]. The mean duration fo CBP in patients who doesn't develop effusion was 73 min [32 min, 110 min]. The comparison between two groups was statically significant (p=0.05).Conclusion:Our study shows that patients who underwent CAPG develop more pleural effusion than other cardiac surgery. Longer duration of CBP is associated with higher risk of pleural effusions. ER -
