Background: Preoperative anxiety affects up to 65% of children who undergo anesthesia induction and often results in uncooperative behavior. Electronic devices have been used to distract children to reduce anxiety and create a more enjoyable preoperative experience. Few studies have compared the effects of different video delivery systems on preoperative anxiety., Aims: The primary aim was to determine if a large projection-based video screen mounted to a patient's bed decreased anxiety when compared to a tablet during mask induction of anesthesia in children from 4-10 years of age., Methods: We performed a prospective, randomized trial to determine differences in our primary outcome, preoperative anxiety, between the large Bedside Entertainment and Relaxation Theater (BERT) and a smaller tablet screen. Secondary outcomes included (a) induction compliance; (b) child fear; (c) frequency of emergence delirium; and (d) satisfaction., Results: In examining the primary outcome for 52 patients, there was a main effect for time on mYPAS scores, f(2, 51) = 13.18, P < 0.01. mYPAS scores significantly increased across time for both groups. The interaction for time (T0, T1 or T2) × group (BERT vs Tablet) was not significant, f(2, 51) = 1.96, P = 0.15; thus changes in mYPAS scores across time did not differ by group status. There was no significant difference in induction compliance, child fear, emergence delirium, or satisfaction between the two groups., Conclusion: In a low-risk population, preoperative anxiety was low and induction compliance was high when pairing screen-based distraction interventions, regardless of size, with parental presence at induction of anesthesia., (© 2019 John Wiley & Sons Ltd.)

Introduction: Pediatric perioperative anxiety is a significant problem during mask induction for general anesthesia. Immersive technologies, such as extended reality headsets, are a promising strategy for alleviating anxiety. Our primary aim was to investigate mask acceptance during inhalational induction utilizing augmented reality (AR). Methods: This was a prospective, matched case-control study at a quaternary academic hospital. Fifty pediatric patients using AR for mask induction were matched to 150 standard-of-care (SOC) controls. The primary outcome was measured with the Mask Acceptance Scale (MAS). Secondary outcomes of cooperation and emergent delirium (ED) were assessed. Results: MAS scores ≥2 occurred at 4% (95% CI [0, 9.4%]) with AR versus 19.3%, (95% CI [13%, 25.7%]) with SOC (RR 0.21, 95% CI [0.05, 0.84], P =.027). Ninety-eight percent of AR patients were cooperative versus 91.3% with SOC (P =.457). Zero percent had ED with AR versus 0.7% with SOC (P = 1.000). Conclusions: AR during mask induction improved mask acceptance compared to SOC. No relationship was observed between AR and cooperation or ED. Future research will investigate the integration of AR into clinical practice as a nonpharmacologic intervention. [ABSTRACT FROM AUTHOR]

Background: Uncooperative pediatric mask induction is linked to perioperative anxiety. Although some risk factors for uncooperative inductions have been reported, there are no large cohort studies that identify intrinsic patient characteristics associated with cooperation. Aim: The primary aim was to identify patient characteristics associated with cooperative mask inductions. The secondary aim was to determine whether preoperative interventions were associated with increased cooperation. Methods: This retrospective cohort study included patients 2‐11 years old and ASA class I‐IV who underwent mask induction. Our primary outcome of interest was cooperation with mask induction, which was correlated against the Induction Compliance Checklist. The variables analyzed for association with cooperation were age, sex, ASA class, class of surgery, preferred language, and race. Interventions examined for association with induction cooperation included premedication with midazolam, exposure to distraction technology, parental presence, and the presence of a Child Life Specialist. Multivariate mixed‐effects logistic regression was used to assess the relationship between patient characteristics and cooperation. A separate multivariate mixed‐effects logistic regression was used to examine the association between preoperative interventions and cooperation. Results: 9692 patients underwent 23 474 procedures during the study period. 3372 patients undergoing 5980 procedures met inclusion criteria. The only patient characteristic associated with increased cooperation was age (OR 1.20, p‐value 0.03). Involvement of Child Life Specialists was associated with increased cooperation (OR 4.44, p‐value = 0.048) while parental/guardian presence was associated with decreased cooperation (OR 0.38, p‐value = 0.002). Conclusion: In this cohort, increasing age was the only patient characteristic found to be associated with increased cooperation with mask induction. Preoperative intervention by a Child Life Specialists was the sole intervention associated with improved cooperation. [ABSTRACT FROM AUTHOR]

Both virtual reality (VR) and exercise are recognized for their analgesic and anxiolytic properties. The purpose of this study is to evaluate the ability of VR-facilitated exercise to modulate pain. Within-subject cross-over clinical trial. The Stanford Chariot Program conducted this study at Lucile Packard Children's Hospital Stanford (LCPHS). Healthy participants meeting inclusion criteria were recruited by volunteer solicitation from LCPHS. Participants were randomized by hand dominance and subjected to a standardized cold pressor test with no VR or exercise. After a 5-min wash-out period, participants repeated the test on their other hand while experiencing a VR-facilitated exercise condition. Pain sensitivity, pain tolerance, and sympathetic activation data were collected during both conditions. Pain sensitivity was scored 0–10 and collected every 30 s. Pain tolerance was recorded as the duration a participant could endure the painful stimuli. Sympathetic activation was measured by skin conductance response density (SCRD) and recorded in 30 s epochs by a biosensor. In all analyses, data were nested by participant. Forty-one participants completed both interventions. Pain sensitivity was reduced in the VR-facilitated exercise condition (p < 0.0001). There was no difference in pain tolerance between conditions. While both conditions resulted in an increase in sympathetic activity, SCRD was higher at all time points in the VR-facilitated exercise condition. The reduction in pain sensitivity indicates VR-facilitated exercise results in improved pain perception. VR-facilitated exercise may be especially useful for patients with chronic pain or other conditions requiring physical therapy, where pain may be exacerbated by exercise. • Using an ice bath and bike, we assessed how VR-facilitated exercise modulates pain. • VR-facilitated exercise reduced pain perception. • VR-facilitated exercise did not change pain tolerance. • Both pain and VR-facilitated exercise induced sympathetic activation. • Sympathetic tone was higher with VR-facilitated exercise at all timepoints.

Study Objective: Virtual reality (VR) is an emerging tool to reduce pain and anxiety during procedures. Although VR's clinical benefits are reported, biometric data quantifying VR's effect on pain tolerance is lacking. We used time-lapse, subjective, and biometric data to evaluate VR's effect on modulating pain.Design: Randomized, controlled crossover within-subject clinical trial.Setting: This study was conducted in the Chariot Lab at Lucile Packard Children's Hospital and outdoors at Stanford University School of Medicine.Patients: 156 healthy volunteers were included.Interventions: Participants underwent pain-inducing ice immersions while connected to biometric sensors. Participants were randomized to immerse their dominant or non-dominant hand with VR or control (no VR) for one immersion, and then crossed-over to the other hand for the second immersion. We instructed participants to submerge their hand until they reached their pain tolerance or until four minutes elapsed.Measurements: Outcomes included ice immersion duration, perceived pain scores, and skin conductance response density (SCRD), a marker of sympathetic arousal. We used survival analysis and mixed effects models to compare measurements with and without VR.Main Results: 153 participants were included in the analysis. Participants with VR were 64% less likely to remove their hands from the ice bath throughout the immersion's duration compared to control (P < 0.001). Participants with VR reported significantly lower pain scores after controlling for dominant hand treatment assignment, VR vs. no VR treatment order, and gender (P < 0.001). SCRD increased as time progressed for both VR and control groups (P = 0.047 combined), with no significant mean group differences.Conclusions: Participants with VR were more likely to survive the 4-min ice bath challenge longer and with lower levels of pain perception, supporting VR's effectiveness as a distraction tool during painful procedures. We observed no differences in sympathetic response when comparing VR to no VR. [ABSTRACT FROM AUTHOR]

Study Objective: HRAD± was developed to quickly evaluate pediatric preprocedural affect and cooperativity during mask induction of anesthesia and peripheral intravenous (PIV) placement. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to compare HRAD± to previously published scales.Design: We conducted an observational study.Setting: Videos of pediatric patients were collected in the perioperative environment.Patients: Twenty-four children, twenty-one pediatric anesthesiologists and twenty pediatric perioperative providers were included.Interventions: To assess the reliability of HRAD±, standard patient videos were created. Children underwent mask induction or PIV placement, and these interventions were video recorded. Mask induction and PIV placement videos were rated by pediatric anesthesiologists and perioperative non-physician providers respectively using HRAD±.Measurements: Two trained researchers provided the modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC) scores, and we calculated correlations to HRAD±, inter-rater reliability, and intra-rater reliability.Main Results: HRAD± scores strongly correlated with mYPAS (r = 0.846, p < 0.0001) and OSBD scores (r = 0.723, p < 0.0001). Cooperativity scores correlated strongly with ICC scores in the mask induction group (r = -0.715, p < 0.0001) and in the PIV group (r = -0.869, p < 0.0001). HRAD± inter-rater reliability for mask induction was 0.414 (p < 0.0001) and for PIV assessment was 0.378 (p < 0.0001). Inter-rater reliability for cooperativity on mask induction was 0.797 (p < 0.0001) and PIV assessment was 0.683 (p < 0.0001). Intra-rater reliability for mask induction was 0.675 and PIV assessments was 0.678. Intra-rater reliability for cooperativity for mask induction was 0.894 and for PIV assessments was 0.765.Conclusions: HRAD± is an efficient and reliable scale that serves as a practical alternative for measuring pediatric affect during mask induction and PIV placement. The results demonstrate strong correlation with commonly utilized yet more complex affect scales. [ABSTRACT FROM AUTHOR]
