Retrospective Cohort Study of Perioperative Complications in Symptomatic and Asymptomatic Children Testing SARS-CoV-2-Positive Within 21 Days Before Surgery.

Introduction: COVID-19 increases anesthetic risk in children, but understanding of complication differences by symptom presence and severity is limited. We hypothesized that symptomatic COVID-19+ children, especially with lower respiratory symptoms, would have higher perioperative complications than asymptomatic patients and that complications would be higher in all patients diagnosed < 6 days before anesthesia.

Methods: This single-center, retrospective cohort study reviewed records of children < 18 years old undergoing surgery with general anesthesia from March 1, 2020, to March 1, 2022, who tested COVID-19+.

Use of Biofeedback-Based Virtual Reality in Pediatric Perioperative and Postoperative Settings: Observational Study.

Background: Biofeedback-based virtual reality (VR-BF) is a novel, nonpharmacologic method for teaching patients how to control their breathing, which in turn increases heart rate variability (HRV) and may reduce pain. Unlike traditional forms of biofeedback, VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of biofeedback. This is the first study to systematically integrate VR-BF use in the pediatric perioperative setting, with the ultimate goal of evaluating the efficacy of VR-BF to reduce pain, anxiety, and opioid consumption once feasibility and acceptability have been established.

Application of behavioral economic strategies to enhance recruitment into a pediatric randomized clinical trial for postoperative pain relief: A randomized clinical trial.

Introduction: A major challenge in conducting clinical trials is recruitment. Trial under-enrollment leads to underpowered studies. Behavioral economics offers strategies that may enhance trial recruitment.

Dataset used to refine a treatment protocol of a biofeedback-based virtual reality intervention for pain and anxiety in children and adolescents undergoing surgery.

There is a great need for nonpharmacologic pain management strategies, given the catastrophic effects of the opioid epidemic and the role of opioid prescription in precipitating addiction [1], particularly in children and adolescents at risk of chronic pain and opioid use after surgery [2], [3], [4]. Biofeedback-based virtual reality (VR-BF) is an innovative approach to managing pain that compliments and may even increase accessibility [5] and acceptability [6] of existing mind-body therapies for pain management, like biofeedback (BF). BF teaches patients behavioral modification techniques that impact involuntary processes [7,8].

Feasibility and acceptability of perioperative application of biofeedback-based virtual reality versus active control for pain and anxiety in children and adolescents undergoing surgery: protocol for a pilot randomised controlled trial.

Introduction: Current clinical applications of virtual reality (VR) provide patients with transient pain relief during acutely painful events by redirecting attention. Biofeedback (BF) is a mind-body therapy that effectively produces sustained pain reduction, but there are obstacles to its routine use. Combined, BF-based VR (VR-BF) may increase accessibility while enhancing the benefits of BF.
