Drainage tubes themselves may induce some complications which can negatively affect the result of the surgery. In this study we assessed a new technique for chest drainage following OPCAB."n"nMethods: In this clinical trial, 171 patients were allocated to two groups. In the control group, the drainage technique included one drain in the left pleural cavity and another in the mediastinum, while in the case group; the drainage technique included one drain in the left plural and one in the right pleural cavity."n"nResults: The amount of drainage in the case group was more than the control group (p=0.001). We found significant reductions in the incidence of arrhythmias in the case group (p=0.005). While one patient (1.2%) needed reoperation for bleeding control in the control group, no patients needed reexploration in the case group (p=0.497). The duration of hospital (p=0.022) and ICU (p=0.002) stays was shorter in the case group."n"nConclusions: Based on the results of this study, changing the position of mediastinal drains in patients undergoing OPCAB surgery and shifting it to the right pleural cavity, reduces complications, such as arrhythmia and pericardial effusion, aside from establishing a better drainage.
