AbstractChest tubes are one cause of pain after cardiac surgery. In a prospective, randomized study, we investigated the effects of the position of chest tubes on acute postoperative pain and pulmonary morbidities in patients who underwent coronary artery bypass grafting. From June through December 2010, 40 patients who underwent elective coronary artery bypass grafting were enrolled in the study. We investigated 2 randomized groups of patients: Group 1 (n-20) had a left chest tube inserted through the midline inferior to the xiphoid process (subxiphoid approach), and Group 2 (n-20) had a left chest tube inserted through the 6th intercostal space along the anterior axillary line (intercostal approach). We compared the results with respect to postoperative pain, the need for analgesic agents, chest-tube drainage, pulmonary morbidities, and duration of hospitalization. The intensity of postoperative pain was similar between the groups. The cumulative doses of analgesic agents, incidence of pulmonary morbidities, and duration of hospitalization were also similar. Pleural effusion and atelectasis were each diagnosed in 3 patients in Group 1 (15%) and 1 patient in Group 2 (5%) (both P=0.68). Two of the patients in Group 1 required drainage of the pleural effusion. In our study, we found that the subxiphoid and intercostal approaches for chest-tube placement yielded similar clinical outcomes.
