Design outcomes

Primary

MeasureTime frame
Outcome expected: 1)-Reduction of the inflammatory response in postoperative coronary artery bypass grafting, assessed by serum levels of Interleukin (IL1, IL6, IL8) and TNFa, C3a, ICAM, CRP, through the samples in the intra-surgery, after induction of anesthesia and postoperative immediately after extubation and after NIV protocol.

Secondary

MeasureTime frame
Expected Outcomes: 1)-Accelerated recovery of volumes and capacities in postoperative coronary artery bypass grafting, assessed by increased forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) compared preoperatively, 1st. 3rd. and 5th. day postoperatively. 2)-Accelerated recovery of respiratory muscle strength in postoperative coronary artery bypass grafting, assessed by increased maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) compared preoperatively, 1st. 3rd. and 5th. day postoperatively. 3)-Improved functional capacity in postoperative coronary artery bypass grafting, assessed by the distance walked during the 6-minute walk test (6MWT) compared preoperatively and 5th. postoperative day. 4)-Improved tissue perfusion and reduced tissue hypoxia in postoperative coronary artery bypass grafting, assessed by reduced dosages of blood lactate and increased central venous oxygen saturation (ScVO2) collected directly from the central venous catheter in intra-surgery after induction of anesthesia and postoperative immediately after extubation and after NIV protocol.;Outcomes found: 1)-Improvement of volumes and capacities in postoperative coronary artery bypass grafting assessed by increased forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) compared preoperatively, 1st. 3rd. and 5th. day postoperatively 2)-recovery of respiratory muscle strength in postoperative coronary artery bypass grafting assessed by increased maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) compared preoperatively, 1st. 3rd. and 5th. day postoperatively 3)-Was not found improvement in functional capacity in postoperative coronary artery bypass grafting, assessed by the distance walked during the 6-minute walk test (6MWT) compared preoperatively and 5th. postoperative day. 4)-Improved tissue perfusion and reduced tissue hypoxia in postoperative coronary artery bypass grafting, assessed
