Virtual Reality for Pediatric Perioperative Preparation

Официальное название

Preoperative Virtual Reality Intervention to Improve the Perioperative Experience in Children Undergoing Elective Surgery: A Pilot Randomized Controlled Trial

Обзор

This pilot randomized controlled trial will evaluate whether a virtual reality (VR) preparation program can improve the perioperative experience of children aged 3 to 12 years undergoing elective surgery. Children scheduled for surgery at HM Hospital in Madrid, Spain, will be randomly assigned to receive either a VR-based educational experience (NixiKit) or the standard preoperative preparation routinely provided by nursing staff. The VR intervention includes an immersive virtual tour of the preoperative area, operating room, and recovery room, designed to familiarize children with the surgical process in an age-appropriate manner. The control group will receive the usual verbal explanation and support provided by nurses before surgery. The study will assess children's fear, preoperative anxiety, cooperation during anesthesia induction, and postoperative pain. Parents' experience and satisfaction with care will also be evaluated. The results of this pilot study will help determine the feasibility and potential effectiveness of VR as a nursing-led preparation strategy for pediatric surgical patients.

Подробное описание

Preoperative anxiety and fear are common among children undergoing elective surgery and may negatively affect cooperation during anesthesia induction, perioperative experience, and postoperative recovery. Educational preparation programs have been developed to help children and their families better understand the surgical process; however, conventional preparation methods may not fully address the emotional needs of pediatric patients.

Virtual reality (VR) has emerged as a promising tool for perioperative preparation by providing immersive and interactive experiences that allow children to become familiar with the hospital environment before surgery. Previous randomized studies and recent systematic reviews have suggested that VR-based preparation may reduce preoperative anxiety and fear while improving cooperation during anesthesia induction and family satisfaction. Nevertheless, evidence remains limited regarding its effectiveness when compared with structured nurse-led preparation delivered as part of routine clinical practice, particularly in real-world hospital settings.

This pilot study aims to evaluate the feasibility and potential effectiveness of a VR-based preoperative preparation program for pediatric patients undergoing elective surgery. The intervention uses the NixiKit system, which provides an immersive virtual tour of the perioperative journey, including the preoperative area, operating room, and recovery room, through age-appropriate audiovisual content designed to familiarize children with the surgical environment.

Participants assigned to the intervention group will receive the VR experience during hospital admission before surgery. Participants assigned to the comparison group will receive the standard preoperative preparation routinely delivered by nursing staff. Data collected during the perioperative period will be used to explore the impact of the intervention on psychological and behavioral outcomes in children as well as on family experience.

As a pilot randomized controlled trial, this study is intended to provide preliminary estimates of intervention effects, assess study procedures and feasibility, and generate information to support the design of a future definitive multicenter trial evaluating virtual reality as a perioperative preparation strategy in pediatric surgical care.

Вмешательства

• Устройство NixiKit Virtual Reality Preparation
  Participants assigned to the intervention group will receive a virtual reality-based preoperative preparation program using the NixiKit system (Nixi for Children). The intervention consists of an immersive 360-degree virtual tour delivered through a pediatric virtual reality headset connected to a smartphone. The experience guides children through the perioperative journey, including the preoperative area, operating room, and recovery room, using age-appropriate narration and storytelling design
• Поведенческое Standard Nursing Preoperative Preparation
  Participants assigned to the control group will receive the standard preoperative preparation routinely provided by nursing staff. This preparation includes a verbal explanation of the perioperative process, including transfer to the preoperative area, operating room procedures, anesthesia induction, and postoperative recovery, as well as the opportunity for children and their parents to ask questions and receive clarification about the surgical process.
