Effects of Rehabilitation on Pulmonary Function in Patients Undergoing Coronary Artery Bypass Graft: A Clinical Trial Study

Prevention of pulmonary complications after coronary artery bypass graft is an important fact. The aim of this study was to evaluate the role of pulmonary rehabilitation prior to the surgery for reducing the risk of pulmonary complications after surgery. In a randomized clinical trial, 60 patients undergoing heart surgery randomly were divided into two groups (Group A and B). In group A Patients was performed physiotherapy before and after chest physiotherapy surgery, but on patients in group B were done only chest physiotherapy after surgery. Effects of preoperative pulmonary rehabilitation were compared between two groups, using Spirometry, arterial blood gas (ABG), Visual Analog Scale (VAS) and 6 Minutes Walking Test (6MWT). Thirty Nine males (65%) and 21 females (35%) patients with a mean age of 56.9 ± 10.8 was been analyzed. Pneumonia after surgery was observed lower in the group A in compared with group B (0% VS. 40%). The mean difference in PCO2 and HCO3 indices (of ABG parameters), mean oxygen saturation (Spo2) (of 6MWT parameters) and VAS index were significantly different in the A and B groups (respectively; P =.008 and P =.001, P <.0001 and P <.0001). The pulmonary rehabilitation program before surgery is recommended to reduce complications of heart surgery.
