Purpose of the research; The aim of this study is to determine the effect of informing patients with video before heart surgery on their intensive care experience."Patient Descriptive Information Form" and "Intensive Care Experience Scale (ICES)" will be used to collect data.In Kavuncu's study, the average score they got from ICES was found to be 57.07±5.6. It was calculated that 45 patients from each group should be included in the study in order to test the 0.6-unit effect size value, which was calculated by accepting a 5% difference from this score in the experimental group, with a 5% margin of error, 95% confidence level and 80% power value.In the study, after the patients admitted to the cardiovascular surgery service for cardiac surgery were informed about the purpose and importance of the study and the research, informed consent will be obtained verbally and in writing from the volunteer patients. In order to ensure randomization of the patients in the study, a randomization plan was prepared for 45 experiments and 45 controls using a probabilistic scheme-based computer program.

In order to ensure randomization of the patients in the study, a randomization plan was prepared for 45 experiments and 45 controls using a probabilistic scheme-based computer program. 24-48 hours before the surgery, the patients will be shown an informative video about the intensive care environment in a separate room through a one-on-one interview. In the study, no attempt will be made to the control group patients other than the routine practice of the institution before the surgery. In the study, the day of discharge from the intensive care unit will be counted as the first day, and on the second day, the 'Intensive Care Experience Scale' will be applied to the patients in both the experimental and control groups by face-to-face interview method.
