Interactive video game built for mask induction in pediatric patients

To the Editor,
Induction of anesthesia is a stressful event for many pediatric patients. Preoperative distress has been correlated with postoperative agitation, negative behaviors, and increased postoperative pain.1 We recently introduced the “Sevo the Dragon” video game as a non-pharmacologic audiovisual intervention technique to reduce anxiety during induction. Consent to describe the case utilizing this technique was obtained from the patient’s mother.
A six-year-old girl with a history of renal failure secondary to renal osteodystrophy and kidney transplant presented for a transplanted kidney biopsy. The patient had required physical restraint during a prior inhalational induction. On presentation for the biopsy, she appeared anxious, clutching her mother and communicating only through her. We discussed various anxiolytic options with the patient and her mother, including oral medications, video tablets, video projection through the Bedside Entertainment and Relaxation Theatre (BERT),2 and an interactive video game built on the BERT platform. The patient elected to try the interactive video game titled “Sevo the Dragon”.
This case illustrates successful application of an interactive video game on the BERT platform. Although audiovisual distraction for inhalational induction in pediatric cases has been described,3 most interactive video game systems are television- or tablet-based, with which children are generally familiar. In contrast, the use of BERT’s large theatrical screen is supported by studies that detailed an association between the large size of the images and patients’ emotional engagement with them.2 Other studies have shown the importance of novel vs familiar stimuli in capturing a patient’s attention.4 In our case, both mother and patient were completely engrossed throughout the process. The mother later thanked the team, saying that the induction was “so cool.”
The other unique feature of the game is that it not only distracts the child, it promotes cooperation with mask induction by encouraging deep breathing. By normalizing the breathing experience at induction via incorporating it into the game play, the patient displays a greater willingness to participate in the inhalational induction. A similar concept, the “ blow up the balloon” method, has been employed for many years.5 The major drawbacks of the “balloon” technique are that it is difficult to keep the child focused on blowing and watching the reservoir bag, which is attached to the intimidating anesthesia machine that is often poorly positioned ergonomically behind the patient. In contrast, our system combines the large screen and the interactive game projected in front of the child, which may be important factors for the efficacy of the “Sevo the Dragon” experience. The release date of this free android game is planned for August 1, 2017 on our website (chariot.stanford.edu).
