Risk factors for hemodynamics change after cabg surgery in southwest of Iran.

Abstract

Coronary artery diseases are the first and most common cause of death in all ages. Heart surgery, as a common therapeutic intervention for patients with coronary artery disease, is considered a necessary treatment. However, patients demonstrate several pre- and post-operative complications. Among the common postoperative complications of coronary artery bypass grafting (CABG) are hemodynamic changes that are still considered a major problem. This study was to determine the extent of hemodynamic changes after coronary artery grafting along with relevant factors in patients under open heart surgery hospitalized in the heart surgery intensive care units. This was a descriptive study, and the sample population consisted of patients who had undergone coronary artery bypass surgery in Ahvaz Golestan Hospital. Files of 100 patients qualified to take part in the study were selected by employing the simple sampling method, and the required information was extracted from them using a checklist. The chi-square test and regression analysis were used to analyze the data. Research findings indicated that 35% of patients experienced postoperative systolic blood pressure changes out of the normal range, 45% experienced diastolic blood pressure changes, Moreover, the relationship of hemodynamic variables with interfering factors such as body mass index (BMI), ejection fraction, history of myocardial infraction, duration of cardiopulmonary machine use, hypothermia, and levels of hemoglobin and hematocrit was found to be significant. Findings of this research can be used for planning on the early prevention, diagnosis and treatment of the possible complications that can be experienced by patients undergoing coronary artery bypass grafting. This will result in the improvement of the quality of care provided to these patients.
