THE EFFECT OF EDUCATIONAL VIDEOS ON PREOPERATION ANXIETY AMONG PATIENTS BEFORE UNDERGOING OPEN HEART SURGERYWITHOUT PUMP

pre-operative anxiety is one of the prominent psychological problems among
people who are going to have open-heart surgeries. If it is not controlled properly, this problem can
cause negative effects on the operation results and the physical status of the patients. Various training
tools and methodologies have been proposed till now, but there is no single agreement among researches
about the best one. The present research wants to determine the effect of educational videos on preoperation anxiety among patients undergoing open-heart surgery without pump.
Materials & Method: This study was single bind and random clinical trial which conducted by the
participation of 60 patient’s candidate for open-heart surgery in the cardiovascular ward of Imam Reza
Hospital of Mashhad in 2015. The patients were divided into control and intervention groups randomly
and assigned to two groups of 30. 15-minute of educational movie in 2 sessions was shown for
patients in the intervention group, but pamphlets and face to face education was applied to those in the
control group one day prior to the operation. The anxiety levels in both groups were measured before
and after the intervention using Spiel Berger state-trait anxiety inventory. SPSS version 11.5,
independent t tests, Mann-Whitney test, paired t test, Wilcoxon test, chi-square test and exact chi-square
test were used to analyze the data.
Results: the average age of the patients was 56.8 ± 4.5 years and the highest school degeree among
53.3% of them was elementary school. In pre-intervention phase, no statistically significant difference
was observed between the average score of the concealed and obvious anxiety in both control and
intervention group members (p>0.05). After the invention, the average obvious anxiety score of those
patients in the control group (27.7 ± 4.2) was significantly less than what was observed in the control
group (33.0 ± 5.3) (p<0.001). After the intervention, the average concealed stress score of those in the
intervention group (29.3 ± 4.1) was significantly lower than the control group (32.2 ± 5.0) (p=0.025).
Conclusion: As a result, the educational movie was more effective than pamphlets and face to face
training in reducing the pre-operation anxiety of the patients. Therefore, it is recommended that the
educational movies were used based on factors such as: the educational status of the patient, the
conditions, and the equipments of the ward
