Summary

This study will evaluate the profilatic effects of inspiratory muscle training (IMT) on functional capacity, respiratory muscle strength, postoperative pulmonary complications and days of hospitalization (PPC) in patients submitted to coronary artery bypass graft surgery (CABG).

Detailed description

Patients undergoing coronary artery bypass graft surgery are at risk of postoperative pulmonary complications, which lead to increased postoperative morbidity and mortality. A few studies have demonstrated that preoperative physical therapy has advantages over postoperative care in patients undergoing cardiac . In this way, this study aim to investigate the effects of preoperativeinspiratory muscle training in patients at high risk of postoperative pulmonary complications who were scheduled for coronary artery bypass graft surgery.

Conditions

• Heart Diseases
• Coronary Disease
• Cardiovascular Diseases
• Coronary Artery Occlusion

Interventions

Type	Name	Description
OTHER	Inspiratory Muscle Training	The inspiratory muscle training (IMT) will be carried out in the IG with Threshold® IMT (Respironics New Jersey, Inc) consisting of a unidirectional flow control valve which assures the constant resistance (linear load) between 7 and 41cmH20. The IMT will be carried out in the sitting position with a load of 30% of the MIP during the two weeks preceding the surgery, seven days a week, twice daily in three series of ten repetitions with a 30 second interval between series, under the supervision of a physiotherapist. A load of 15% of the MIP was used only on the first day of training in order for the individual to adapt to the equipment. Subsequently, the 30% MIP load will be applied and readjusted according to the new MIP values determined every four days.
