Abstract
Abstract
Cardiac surgery involves increased anxiety associated with lack of knowledge about the procedure. Thus, health education can be beneficial as a technological tool in the preoperative period for self-care and control of patient anxiety. The objective was to evaluate the effect of the audiovisual resource in the acquisition of knowledge about the level of anxiety in the preoperative period of myocardial revascularization. Randomized clinical trial with 44 patients in the preoperative period of coronary artery bypass grafting, equally divided into two groups. The control group (CG N = 22) received only verbal instructions and the experimental group (EG N = 22) received intervention from an audiovisual resource. Data were collected through a knowledge questionnaire and the State-Trait Anxiety Inventory. The analysis was performed using Student's t, chi-square and Fisher's exact tests. There was a statistically significant difference in favor of the group that received the intervention with the audiovisual resource, in addition to an increase in positive feelings after preoperative guidance. The effectiveness of the video in nursing guidance in the preoperative period of cardiac surgery was verified, facilitating the surgical process for the patient and offering a tool for the nurses' work process for an evidence-based practice. Trial registration: the Brazilian Clinical Trials Registry (REBEC) platform under number RBR-24c5qwm (27/05/2021).
