RESUMEN
PURPOSE: This study was conducted to determine the effect of providing preprocedural education to patients undergoing coronary angiography on their vital signs. DESIGN: The study was a randomized controlled experimental study with a pretest/post-test control group design. METHODS: The study was conducted in the Cardiology Service of a hospital in Eskisehir between November 2021 and April 2022. Power analysis identified that it was appropriate to include 79 individuals in the experimental group, 79 individuals in the control group, and a total of 158 individuals. The experimental group was trained using the "Structured Education Manual" prepared by the researchers. FINDINGS: The education had an influence on the stabilization of vital signs after the procedure compared to preprocedure. When the comparison of vital signs before and after the education was analyzed, systolic blood pressure and diastolic blood pressure differed significantly between 11 measurements in both groups (P < .05). The systolic and diastolic blood pressure of the experimental group measured before the procedure was higher than their other measurements after the procedure. Heart rate, respiratory rate, and saturation value in both groups displayed a statistically significant difference between 11 measurements (P < .05). In the experimental group, heart rate and respiratory rate before the procedure were higher than the postprocedure measurements. The saturation value of the experimental group at 150 minutes after the procedure was higher than the other measurements. CONCLUSIONS: Education given to patients before undergoing a coronary angiography procedure had a positive effect on the patients' vital signs. It is recommended that patients undergoing a coronary angiography procedure be provided with audio-visual training by nurses before the procedure.
