Effects of Preoperative Education on Anxiety and Emergence Agitation

This randomized controlled trial aims to evaluate the effect of structured preoperative education focused on the anesthesia emergence process on preoperative anxiety and postoperative emergence agitation in adult surgical patients undergoing general anesthesia. Emergence agitation is a frequent postoperative complication associated with patient discomfort, safety risks, and increased clinical workload. Preoperative anxiety is considered a modifiable risk factor for emergence agitation; however, evidence-based educational interventions targeting the emergence phase are limited. The intervention consists of a standardized, nurse-led preoperative education program providing information on general anesthesia, endotracheal intubation and extubation, the post-anesthesia care unit environment, and expected physical and emotional responses during emergence. Education is delivered through a face-to-face individual session supported by written materials. Patients in the control group receive routine perioperative verbal information in accordance with standard care. Eligible adult patients scheduled for elective general surgery under general anesthesia will be randomly assigned to either the intervention or control group. Preoperative anxiety will be assessed using the Amsterdam Preoperative Anxiety and Information Scale (APAIS). Emergence agitation will be evaluated in the post-anesthesia care unit using the Riker Sedation-Agitation Scale (SAS) and the Richmond Agitation-Sedation Scale (RASS) during the first 30 minutes after surgery. The primary outcomes are preoperative anxiety levels and the incidence of postoperative emergence agitation. Secondary outcomes include postoperative pain, extubation time and quality, and length of stay in the post-anesthesia care unit. This study seeks to determine whether emergence-focused preoperative education can improve perioperative psychological outcomes and enhance patient safety in surgical care.
