Preprocedural Video Education for Bronchoscopy Anxiety

The goal of this clinical trial is to learn whether preprocedural video education can reduce anxiety in adult patients who are scheduled to undergo bronchoscopy under general anesthesia. It will compare video-based education with standard verbal education. The main questions it aims to answer are: Does video education reduce preprocedural anxiety, as measured by the Amsterdam Preoperative Anxiety and Information Scale (APAIS), in patients undergoing bronchoscopy under general anesthesia? Researchers will compare patients who receive audiovisual education with those who receive standard verbal education to see whether video education provides greater anxiety reduction before bronchoscopy under general anesthesia. Participants will: 1. Complete an APAIS questionnaire before receiving preprocedural education 2. Receive either video-based education using a tablet or standard verbal education with a question-and-answer session 3. Complete another APAIS questionnaire immediately after the education session

Inclusion Criteria: 1. Adult patients aged ≥18 years who are scheduled to undergo bronchoscopy under general anesthesia. 2. Patients with no previous history of medical procedures performed under general anesthesia. 3. Patients with an American Society of Anesthesiologists (ASA) physical status classification of I-III. 4. Patients who are willing to participate in the study and have provided written informed consent. Exclusion Criteria: 1. Patients who are unable to read and write. 2. Patients with significant hearing and/or visual impairment. 3. Patients with cognitive or mental disorders identified from the patient's medical record. 4. Patients with a history of antipsychotic or benzodiazepine use.
