Abstract
Background: Organs and tissue perfusion are generally affected because of intraoperative, respiratory and cardiovascular frameworks after heart surgeries. Nursing activities has crucial benefits on hemodynamic and perfusion boundary. Aim: To determine the effects of planned exercise ontissue perfusion improvement  post coronary artery bypass graft.A quasi-experimental design was used within the present study. Setting: The study was carried out at the cardiothoracic intensive care unit at Assiut University Hospital. Sample: A convenience sample of 60 patients with open heart surgery from both sex assigned into two equal groups (control and study groups) from age 18 years and above. Tools: Patients assessment sheet that include, part one is concerned with the patient's basic health data and part two involved the hemodynamic indices and tissue perfusion parameters in preoperative and 1^st,  ,3^rd and 5^th days post-operative.Results:It was revealed that there was a statistically significant difference between the two groups after the surgery as regards to capillary refill  on 3^rd and 5^th day(p=0.002) and also as regards to mean blood pressure on the 3^rd  day (p=0.017). Conclusion: exercise as a part of nursing intervention had a significant impact on tissue perfusion parameter of postoperative cardiac patients. Recommendation: planned exercises for postoperative cardiac patients should be offered on a regular basis.
