An interventional study of Animation-Assisted Preoperative Information in Preoperative Anxiety, sponsored by Ankara City Hospital Bilkent. Not yet recruiting. Open to participants aged 12 Years to 17 Years. Per ClinicalTrials.gov, last updated 2026-10-30.
Sponsored by Ankara City Hospital Bilkent · Not applicable, Interventional, and Supportive care
This study aims to find out whether adding a short educational animation to standard preoperative information can help reduce anxiety in adolescents aged 12-17 years who are scheduled for elective surgery.
A total of 148 adolescents will participate in this randomized controlled study. Participants will be randomly assigned to one of two groups. The first group will receive standard verbal and written information about anesthesia. The second group will receive the same information along with an age-appropriate educational animation explaining what to expect before, during, and after anesthesia.
Participants will be asked to rate their anxiety before receiving information in the preoperative waiting area and again in the operating room before receiving any sedative medication or anesthesia. The researchers will compare how anxiety levels change between the two groups.
The study will also assess heart rate, blood pressure, parental anxiety, satisfaction with the information provided, and adolescents' feelings about their upcoming surgery.
The findings may help healthcare professionals improve the way adolescents and their families are prepared for anesthesia and surgery.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants in this group will receive standard verbal and written preoperative anesthesia information supplemented with a standardized, age-appropriate educational animation. The animation will be presented in the preoperative waiting area before administration of sedative or anxiolytic medication. Preoperative anxiety will be assessed before and after the educational intervention.
Behavioral: Animation-Assisted Preoperative Information
Participants allocated to the intervention group will receive standard verbal and written preoperative anesthesia information supplemented by a standardized, age-appropriate educational animation. The animation will explain the perioperative process, including preparation before surgery, transfer to the operating room, anesthesia administration, and recovery after anesthesia, using clear and reassuring language suitable for adolescents aged 12-17 years. The animation will be presented in the preoperative waiting area before administration of any sedative or anxiolytic medication. Participants in the control group will receive standard verbal and written preoperative information without the animation.
Change in Preoperative Anxiety Score (VAS-A) From Baseline to Pre-Induction
Adolescent preoperative anxiety will be assessed using a self-reported Visual Analog Scale for Anxiety (VAS-A), ranging from 0 (no anxiety) to 10 (maximum anxiety). Anxiety will be measured at two time points: T0, in the preoperative waiting area before the educational intervention, and T1, on the operating room table before administration of sedative medication or anesthesia induction. The primary outcome will be the between-group difference in the change in VAS-A scores (T1 minus T0). Lower scores indicate less anxiety, and a negative change indicates a reduction in anxiety.
Time frame: From baseline in the preoperative waiting area (T0) to immediately before anesthesia induction in the operating room (T1), on the day of surgery.
