Effects of Respiratory Muscle Training on Postoperative Pulmonary Complications of Cardiac Surgery

Effects of Preoperative Inspiratory Muscle Training on Functional Capacity and Pulmonary Complications in Coronary Artery Bypass Graft Surgery

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).

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.

Inclusion Criteria:

• High-risk patients underwent primary elective CABG (Coronary artery bypass graft), High-risk will be defined as 2 or more the following: age>70 years; cough and expectoration; diabetes; smoker; COPD (Chronic Obstructive Pulmonary Disease)

Exclusion Criteria:

• Uncontrolled arrhythmia,
• Decompensated heart failure,
• Unstable angina upon selection or during the inspiratory muscle training (IMT),
• Need for reoperation and association of another procedure during surgery (e.g. valve correction associated with CABG)
• Severe orthopedic or neurological conditions.
