Evaluation of Inspiratory Muscle Strength Early After Coronary Artery Bypass
31. marts 2009 opdateret af: Hospital de Clinicas de Porto Alegre
Inspiratory Muscle Strength as a Determinant of Functional Capacity Early After Coronary Artery Bypass Graft Surgery
The purpose of this study is to evaluate the effects of a 6-day postoperative in hospital cardiopulmonary rehabilitation program on inspiratory muscle strength and its potential association with improved functional capacity after coronary artery bypass grafting surgery.

Detaljeret beskrivelse
Eligible patients were randomized to a cardiopulmonary rehabilitation program (Rehab; n = 10) or to usual care (Control; n = 10).
The randomization was done by the Graphpad StatMate computerized program.
Those patients assigned to Control were followed by their own physicians, received routine nursing assistance, were visited daily by the one of the investigators (CPM), but were not exposed to any specific respiratory or motor physical intervention.
Those randomized to Rehab received the same medical and nursing care, but followed a structured physical therapy program twice a day.

The program consisted of bronchial hygiene characterized by detachment and removal of secretions and respiratory exercises which were applied in the respiratory muscles in order to strengthen and increase the resistance.
Patients were instructed to maintain diaphragmatic breathing, at a rate of 12 to 18 breaths per minute during EPAP mask use, and the expiratory pressure was increased progressively in the following fashion: 3-8 cm H2O during 3-12 minutes.
Also, they performed flexion/extension of hip and knee, active free exercises for upper limbs, ambulation exercise and ascent/descend of stairs
