Effect of Education by Visual Compact Disc on Two time- period of Pre-operation Anxiety of Patients who were Candidates for Coronary Artery Bypass Graft [CABG]

Today, arthrosclerosis of coronary arteries is one of the most common life threatening diseases in patients. In fact, Coronary Artery Bypass [CABG] is high risk surgery in both developed and developing countries and heart is a vital organ that is susceptible for any disorders which could be life theatening, because of undergoing CABG patients with high anxiety and stress. Due to surgery anxiety, heart rate, cardiac output and oxygen demand will rise. Then any attempt to decrease patients' preoperational anxiety would be beneficial. One of the efforts to decrease the anxiety level is patient education. There are different viewpoints about educational methods in the literature. This study was a randomized clinical trial with the purpose of determination of the effect of education with visual compact disc [VCD] on the patients' anxiety at the first day and sixth day of admission. Sixty patients were included, 30 were assigned into experimental group and 30 subjects into control group. Sampling method was consecutive. The Spielbergers' questionnaire was used for data collection pre and post educational intervention. The result indicated that the late trait anxiety level significantly decreased in the experimental group compared to the control group at the 6th day before CABG [t=3.79, P=0.001] [t=4.53, P=0.00] respectively. According to the study results, use of visual information by VCD at sixth day before surgery was more effective in clinical setting that the first day. Therefore, nurses can use this educational cost-effective beneficial intervention, for reducing the patients' anxiety

effect of education by a booklet at two time Periods on pre-operation Anxiety in patients as candidates of Coronary Artery Bypass Graft [CABG]

Extensive surgical interventions as diagnostic and therapeutic methods can cause anxiety in patients. Therefore, health care professionals such as nurses should try to reduce the level of patients' anxiety by addressing beneficial effects of providing preoperative information. The main purpose of the study was to determine the effect of education using a booklet in different times [1 day and 6 day before surgery] on anxiety level of patients as candidates for Coronary Artery Bypass Graft [CABG], in Tehran Heart Center Hospital, 2006. The study design was a clinical trial. The total sample size was 60 patients. Thirty subjects were given a booklet 1 day before surgery and another group, received education, 6 days before surgery. Sampling method was consecutive. The Spiellberger's State-Trait Anxiety Inventory was used for data collection at pre and post education. The result indicated that the anxiety level decreased in both groups, but paired t-test showed that the difference of state anxiety and trait anxiety in the first group [received education at 1 day before operation] at pre and post intervention were statistically significant [t=3.27, P.value=0.030], [t=2.23, P.value=0.034] respectively, whereas there was not statistically significant difference of anxiety level in the group of patient who received education 6 days before the surgery, at pre and post intervention. According to the results, providing educational booklets to the patients in clinical setting one day before surgery, seems more applicable which could reduce patients' anxiety effectively
