Effectiveness of Early Mobilization in Prevention and Rehabilitation of Functional Impairment After Myocardial Revascularization Surgery: A Systematic Review

Introduction: Myocardial revascularization surgery is associated with high morbidity and mortality, due to factors like the general anesthesia and the surgical procedure itself. Physiotherapy, combined with early mobilization (EM), can provide the patient with better functional parameters. Objective: To review, identify and describe the effectiveness of EM in the prevention and rehabilitation of functional parameters of coronary artery bypass graft surgery. Methodology: This is a systematic review conducted between February 2020 and 2021 of randomized clinical trials (RCTs) published in the Cochrane databases Library, LILACS, Scielo and Medline / PubMed. The Physiotherapy Evidence Database (PEDro) scale was used for assessment of the methodological quality of studies included. Results: Four studies were reviewed. Two articles assessed functional capacity, one using the cycle ergometer and one with inspiratory muscle training (IMT) together with active exercises and early walking. One article reported a reduction in the incidence of atelectasis and pleural effusion with EM and one article reported improvements in the alveolus-artery gradient and inspiratory muscle power using an inspiratory muscle trainer combined with EM. Conclusion: EM is effective in the prevention and rehabilitation of functional parameters after CABG surgery, by improving functional capacity, respiratory muscle power, quality of life and gas exchange, and reducing the incidence of atelectasis and pleural effusion.
