Background and Objectives: We investigated the efficacy of pleural drainage with the use of different chest tube methods in patients after coronary artery bypass graft (CABG) surgery. Design and Setting: Prospective randomized study of 60 patients undergoing elective on-pump single CABG surgery. Patients and Methods: The left internal mammary arterial grafts were harvested from all patients. The patients were separated into three groups: In one group (IC6, n=20), pleural tubes were inserted through the sixth intercostal space at the midaxillary line; in the second group (SX-r, n=20), rigid straight pleural tubes were inserted from the mediastinum through the subxiphoid area; and in the third group (SX-s, n=20), soft curved drainage tubes were inserted from the mediastinum through the subxiphoid area. The residual pleural effusion was examined by multislice CT scans within 8 hours of removal of the drainage tubes. Pain was evaluated according to standard methods. Results: The groups did not differ with respect to volume of residual pleural effusion (P >.05). The IC6 group had a higher mean pain score than the other two groups (P .05). IC6 group patients had a higher requirement for analgesics. The rate of atelectasis was higher in group IC6 (P
