Pleural subxyphoid drain confers better pulmonary function and clinical outcomes in XXXX after off-pump coronary artery bypass grafting: a randomized controlled trial.

@entity1 @entity1143 @entity891 @entity158 @entity1030
UNASSIGNED: Objective: To evaluate the lung function and clinical outcome in severe @entity1030 in @entity1 undergoing off-pump coronary artery bypass grafting with left internal thoracic artery graft, comparing the pleural drain insertion in the intercostal versus subxyphoid region. Methods: A randomized controlled trial. @entity1030 @entity1 were randomized into two groups according pleural drain site: II group (n=27) - pleural drain in intercostal space; SI group (n=29) - pleural drain in the subxyphoid region. Spirometry values (Forced Vital Capacity - and Forced expiratory volume in 1 second) were obtained on preoperative and 1, 3 and 5 postoperative days. Chest x-ray from preoperative until postoperative day 5 (POD5) was performed for monitoring respiratory events, such as @entity891 and @entity1143 . Pulmonary shunt fraction and @entity158 score was evaluate preoperatively and on postoperative day 1. Results: In both groups there was a significant decrease of the spirometry values (Forced Vital Capacity and Forced expiratory volume in 1 second) until POD5 (P<0.05). However, when compared, SI group presented less decrease in these parameters (P<0.05). Pulmonary shunt fraction was significantly lower in SI group (P<0.05). Respiratory events, @entity158 score, orotracheal intubation time and postoperative length of hospital stay were lower in the SI group (P<0.05). Conclusion: Subxyphoid pleural drainage in severe @entity1030 @entity1 determined better preservation and recovery of pulmonary capacity and volumes with lower pulmonary shunt fraction and better clinical outcomes on early postoperative off-pump coronary artery bypass grafting.
