  Background and Objective: After coronary artery bypass surgery, pulmonary complications and oxygenation disorders are common, which have an important role in disablement and mortality. Different methods are used for improvement of pulmonary function and oxygenation. In this study we aimed at evaluating the effect of deep breathing exercise on arterial blood gases after CABG.

  

  Material and methods: This clinical trial was conducted on fifty patients who had CABG in Chamran hospital and Sina heart center of Isfahan, 2012. The patients were randomly located in groups of intervention and control. The intervention was the use of deep breathing exercises initiated after extubation while just the routine breathing exercises were used for control group. Arterial blood gases of all patients were measured before surgery, after extubation, second and the third postoperative days, and analyzed by independent t test.

  

  Results: the arterial blood gases measured in before surgery, after extubation, first and second days were the same in intervention and control groups. In the third postoperative day, there was a significant difference in the mean of arterial blood oxygen (81.3±4.6 vs. 72.7±7.1 respectively, p=0.01), arterial blood carbon dioxide (37 ±1.9 vs. 43.7±3.2 respectively, p >0.001) and oxygen saturation (96.8±1/4 vs. 90.5±2.1 respectively, p >0.001).

  

  Conclusion : in terms of the results, the deep breathing exercise is significantly more effective in improvement of blood arterial gases parameters.

Background and objective: Coronary Bypass Graft Surgery (CBG) is one of the therapeutic approaches having the leading effects on the function of the patients. Because of paramount importance of self-efficacy and self-esteem, we aimed to evaluate the effectiveness of family-centered empowerment on the self- efficacy and self-esteem of the patients undergoing coronary bypass surgery.
 Material and Methods: This case control clinical trial was conducted on 102 patients with elective heart surgery and 102 of their active family members in 2011.‌ The patients were selected via convenience sampling and randomly assign ed to experimental and control group. After measuring the self-efficacy and self-esteem, family-centered empowerment care, including individual training, group discussion, film and active participation,‌ was performed in experimental and just routine care in control group. Using PASW statistics-18, we analyzed the data.
Results: The results showed that the two groups were the same considering population variables and the mean scores of self-efficacy and self-esteem. The level of self-efficacy and self-esteem in case group were significantly higher than those of controls (P<0.000). After intervention, the mean score of self-efficacy and self-esteem were increased (P<0.0000).
Conclusion:‌In regard with the results,‌ family-centered ‌empowerment care ‌in patients undergoing CBG is practically feasible , and it can be helpful in improving self-efficacy and self- esteem.
