EVALUATION OF PREOPERATIVE BREATHING TECHNIQUES ON FUNCTIONAL MOBILITY IN ON-PUMP VERSUS OFF-PUMP CORONARY ARTERY BYPASS GRAFT PATIENTS: A COMPREHENSIVE REVIEW

This review investigates and contrasts the effects of various preoperative chest rehabilitation techniques in patients undergoing coronary artery bypass graft (CABG) surgery, both on-pump and off-pump. Utilizing databases such as Pedro, Cochrane, and PubMed, a comprehensive literature review was conducted, focusing on studies published between 2017 and 2023. We identified 14 relevant articles that met specific inclusion and exclusion criteria, examining the effects of preoperative physiotherapy in adult patients undergoing CABG surgery. Preoperative physiotherapy encompasses a variety of approaches, including counselling, cardiovascular exercise, instruction on breathing techniques, and inspiratory muscle training (IMT). Numerous studies have highlighted the benefits of integrating these methods, such as reducing the risk of postoperative pulmonary complications, shortening hospital stays, achieving earlier extubation, and decreasing anxiety. Despite these findings, further research is needed to evaluate the effectiveness of combination therapies, particularly those involving IMT, in preoperative physical therapy. The goal is to develop a comprehensive understanding of the mechanisms through which these treatments reduce pulmonary complications post-surgery.
