Abstract
Background and Objective
Hemodynamic changes are among the common complications after coronary artery bypass graft (CABG) surgery. Incentive spirometry (IS) and deep breathing exercises (DBEs) are widely used in patients undergoing CABG surgery. The aim of the present study was to compare the effect of IS and DBEs on hemodynamic and oxygenation parameters of patients undergoing CABG surgery.
Methods
This is a clinical trial that was performed on 40 patients with heart disease who were candidates for coronary artery bypass graft surgery. Participants were selected using convenience sampling and then randomly divided into two groups. One day before surgery, one group was taught how to perform DBE and the other group was taught how to use IS in practice. Hemodynamic and oxygenation indices were measured and recorded before the intervention, the first, second, and the third day after the intervention. Data analysis was carried out using SPSS ver.16 and descriptive and inferential statistical tests.
Results
The mean systolic blood pressure (SBP) and diastolic blood pressure (DBP) on the first day after the intervention in patients undergoing the IS group was significantly higher than the DBE group (p<0.05). On the third day after the intervention, the mean arterial oxygen saturation (SaO2) in patients of the IS group was significantly higher than the DBE group and the mean respiratory rate (RR) in patients in the IS group was significantly lower than the DBE group (p <0.05). However, there was no significant difference between the two groups in terms of other indices (p> 0.05).
Conclusion
The results showed that IS has a greater effect on hemodynamic and oxygenation indices of patients undergoing CABG compared to DBE, so, it is recommended to use IS to improve hemodynamic and oxygenation indices in these patients.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
