[Prophylactic inspiratory muscle training before coronary artery bypass graft].
Pulmonary complications after cardiac surgery are a leading cause of postoperative morbidity and mortality . Respiratory muscle weakness may contribute to the postoperative pulmonary abnormalities . We hypothesized that : inspiratory muscle strength ( PImax at RV ) and endurance ( PmPeak/PImax ) decrease following  coronary artery bypass grafting ( CABG ) ; that this weakness is associated with impaired pulmonary function tests ( PFT ) , impaired gas exchange and a higher rate of pulmonary complications ; and that prophylactic inspiratory muscle training ( PIMT ) will prevent these changes . 30 c and i date s for CABG , ranging in age from 33 to 79 , were evaluated and r and omized into 2 groups : 15 received PIMT using a threshold trainer for 30 min/day for 1 month before operation , while 15 served as controls and received sham training . There was a significant decrease in respiratory muscle function , PFT , and gas exchange in the control group following CABG , while in the trained group these parameters where similar to those before entering the study . The differences between the groups were statistically significant . In addition , 4 ( 27 % ) in the control group , but only 1 ( 7 % ) in the trained group had postoperative pulmonary complications . We conclude that CABG is followed by significant deterioration in inspiratory muscle function , PFT and arterial blood gases . Decrease in these parameters can be prevented by PIMT , which may also prevent postoperative pulmonary complications
