HRAD± was developed to quickly assess pediatric perioperative affect and cooperation. HRAD± represents: Happy, Relaxed, Anxious, Distressed, with a yes/no answer to cooperativity. The primary aim of this study was to investigate the clinical utility of HRAD± as an affect and cooperation assessment tool for inhalational mask induction. Secondary aims examined inter-rater reliability (IRR) of HRAD± and predictive validity of induction HRAD± with emergence delirium. This was a prospective observational investigation. We conducted this investigation at Lucile Packard Children's Hospital Stanford, an academic, quaternary care children's hospital in Northern California. A total of 197 patients were included in this investigation. Children 1–14 years of age, who underwent daytime procedures with inhalational induction of anesthesia and American Society of Anesthesiologists physical status I-III were eligible. During mask induction, two trained research assistants (RAs) independently scored the patient's affect and cooperation. After extubation, the same investigators observed the patient's emergence. RAs scored each mask induction using the following scales: HRAD±, modified Yale Preoperative Anxiety Scale (mYPAS), Observation Scale of Behavioral Distress (OSBD), and Induction Compliance Checklist (ICC). Correlations were calculated to HRAD±. IRR of HRAD± between the RAs as well as predictive validity of HRAD± to Pediatric Anesthesia Emergence Delirium (PAED), Watcha and Cravero scales were calculated. HRAD± scores strongly correlated with mYPAS (r = 0.840, p < 0.0001) with moderate correlation to OSBD (r = 0.685, p < 0.0001) and ICC (−0.663, p < 0.0001). IRR was moderate for the affect and cooperation portion of the HRAD± scale, respectively (κ = 0.595 [p < 0.0001], κ = 0.478 [p < 0.0001]). A weak correlation was observed with PAED (r = 0.134 [ p = 0.0597]) vs HRAD±. No correlations were observed between Watcha (r = 0.013 [ p = 0.8559]) and Cravero and HRAD± scales (r = 0.002 [ p = 0.9767]). HRAD± is a clinically useful and simple scale for evaluating pediatric affect and cooperation during inhalational mask induction. Results demonstrate correlation with commonly utilized research assessment scales. • Pediatric perioperative anxiety is common with short- and long-term consequences. • Research scales that measure anxiety are complex to use in clinical settings. • HRAD± is a practical scale for evaluating affect & cooperation for mask induction.

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: The erector spinae plane block (ESPB) was first described in 2016 as a regional block for thoracic neuropathic pain. Given its short history, there are a paucity of controlled clinical trials, yet an abundance of case reports. The primary aim of this review is to examine pooled clinical data from published literature to gain an understanding of ESPB characteristics.Design: A PubMed search was conducted to identify all ESPB related publications. Inclusion criteria included reports of ESP single shot, continuous infusion, intermittent bolus, human and cadaveric studies. Only publications obtained in English were included. Measures included type of publication, year and country of publication, journal of publication, block technique, anatomic location, age, opioid and adjunct pain medication use, sensory and motor changes, side effects and adverse events. Qualitative statistics were used.Main Results: The initial search yielded 201 publications. After application of inclusion and exclusion criteria, 85 publications from 21 journals were included in the pooled review which yielded 242 reported cases between 2016 and 2018. The majority of publications reported single shot techniques (80.2%), followed by intermittent boluses (12.0%) and continuous infusions (7.9%). 90.9% reported use of multimodal analgesia in addition to the ESPB and 34.7% reported sensory changes from ESPB. A reduction in opioid use was reported in 34.7% of cases. One adverse event involving a pneumothorax was reported.Conclusions: To our knowledge, this is the first review providing a pooled review of ESPB characteristics. The ESPB appears to be a safe and effective option for multiple types thoracic, abdominal, and extremity surgeries. [ABSTRACT FROM AUTHOR]

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]
