A New Predisposing Factor for Postoperative Atrial Fibrillation: Tube Insertion Site.

Background:  The aim of this study is to compare the insertion sites of drainage tubes placed in the left thorax after elective coronary artery bypass grafting (CABG) surgeries.

Materials And Methods:  Patients were divided into two groups based on the site of tube insertion into the left hemithorax: those with a tube inserted from the subxiphoid region and those with a tube inserted from the left intercostal region. Comparative analyses between these two groups and factor analyses contributing to the outcome were performed.
