RESUMO
PURPOSE: Intravenous (IV) magnesium sulfate (MgSO4) is clinically useful as adjunct therapy in treating acute asthma exacerbations. Despite its clinical utility, the disposition of magnesium in children is poorly described. The purpose of this study is to describe the pharmacokinetics (PK) of ionized and total serum magnesium following IV MgSO4 administration in children with severe acute asthma. METHODS: Thirty-two children receiving 50 mg/kg IV MgSO4 for acute asthma exacerbations at Primary Children's Hospital in Salt Lake City, UT, were prospectively enrolled in the study. Blood samples were collected before, as well as 30 min and 2 h after each child's IV MgSO4 dose, and used to determine total serum and ionized magnesium concentrations. The collected data were analyzed using population PK techniques using NONMEM® software. RESULTS: Total serum magnesium concentrations were used to externally validate our previously published model constructed with retrospective data (median prediction error 10.3%, median absolute prediction error 18.1%). The mean (%CV) observed endogenous ionized magnesium concentration was calculated to be 6.0 mg/L (12%), approximately one third of the same value for endogenous total serum magnesium (17.6 mg/L (22%)) in this dataset. Weight was a significant predictor of both clearance and volume in a population PK model describing ionized magnesium concentrations. No adverse events were observed in this pediatric cohort. CONCLUSIONS: This prospective study supports and extends our previous PK analysis of total serum magnesium concentrations. Ionized and total serum magnesium followed similar PK profiles following IV MgSO4 administration in children. A single bolus infusion of IV MgSO4 was safe in this small sample of children receiving it for acute asthma.

STUDY OBJECTIVE: 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. DESIGN: This was a prospective observational investigation. SETTING: We conducted this investigation at Lucile Packard Children's Hospital Stanford, an academic, quaternary care children's hospital in Northern California. PATIENTS: 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. INTERVENTIONS: 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. MEASUREMENTS: 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. MAIN RESULTS: 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]). CONCLUSIONS: 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 patients and their caregivers often experience perioperative anxiety. Interventions reduce caregiver anxiety improve cooperation and contribute to an improved patient experience. This study seeks to evaluate the efficacy of virtual reality (VR)-assisted mindfulness on perioperative caregiver anxiety. Participants were randomized into a standard of care (SOC) group, which included snacks but no technology-based distractions, or a VR group, which included snacks and a VR-guided meditation. Caregiver anxiety was measured before and after the intervention using the Visual Analogue Scale for Anxiety (VAS-A). Secondary aims explored participants' baseline anxiety with the State-Trait Anxiety Inventory (STAI). VR group participants completed a satisfaction survey. Linear regression models of VAS-A and STAI were used to compare group differences. Satisfaction survey results were reported with descriptive statistics. 26 participants were included, with 12 randomized to the SOC group and 14 to the VR group. VAS-A scores in the VR group were lower than those in the SOC group (p = .002). The STAI found no change in participants' state of anxiety in the SOC group (p = .7108), compared to a significant reduction (p = .014) in the VR group when controlling for anxiety traits. 12 of 14 caregivers in the VR group expressed satisfaction or strong satisfaction. This study supports the implementation of VR mindfulness as a method to reduce caregiver anxiety. VR use in the pediatric healthcare setting is safe and inexpensive, and the intervention had a high degree of participant satisfaction.
RESUMO
BACKGROUND AND OBJECTIVES: A lack of price transparency may contribute to high healthcare costs. US hospitals were mandated to post their charge masters online in 2019. To compare changes in charge master prices of 3 common tests (complete blood count, complete metabolic panel, and chest radiograph) at US children's hospitals between 2019 and 2021. METHODS: Online search for charge master was conducted from July to December 2019 and October to December 2021. Descriptive statistics were reported for each test. Prices between years were adjusted for inflation and compared with paired t test. City-level variation was evaluated by comparing the coefficient of variation in 6 metropolitan areas: Baltimore, California Bay Area, Chicago, Dallas-Fort Worth, Los Angeles, and New York City. RESULTS: Of 847 hospitals, charge masters were found in 747 (88%) in 2021 and 728 (86%) in 2019. Complete blood count prices ranged from $5 to $1037 in 2019 and $5 to $1085 in 2021, with no difference between the 2 years (P = .17). Complete metabolic panel prices ranged from $10 to $2440 in 2019 and $6 to $2746 in 2021, with no difference in prices (P = .75). Chest radiograph prices ranged from $20 to $1900 in 2019 compared with $30 to $5800 in 2021. Prices were higher compared with 2019 ($392 vs. $365, P < .0006). City-level changes in the coefficient of variation showed only 2 cities with reduced coefficients of variation in all 3 tests. CONCLUSIONS: Two years after mandating hospitals post charge masters online, there continues to be tremendous variability in prices of common tests across US children's hospitals.

Introduction: Rapid response teams (RRTs) improve morbidity by reducing the incidence of cardiac arrests. Although providers commonly activate RRTs on acute care wards, they are infrequently used perioperatively. At our institution, two intraoperative calls for help exist: staff assists (SAs) and code blues (CBs). The SA functions analogously to an RRT, and the CB indicates cardiopulmonary arrest. Given the success of RRTs, this project aimed to increase the use of the SA system. Our primary goal was to increase the ratio of SA to CB alerts by 50% within 6 months. Methods: A quality improvement team led this project at an academic pediatric hospital in Northern California. The team analyzed the current state and identified an achievable goal. After developing key drivers, they implemented monthly simulations to teach providers the signs of clinical deterioration and to practice activating the SA system. In addition to measuring the ratio of SA to CB alerts, the team surveyed the etiologies of SA and measured process satisfaction. Results: Before the introduction of this initiative, the ratio of SA to CB alerts were 1:13.3. These improvements efforts led to an increase of SA to CB alerts to 1.5:1 (P = 0.0003). Twenty-three anesthesiologists provided etiologies for SA, reporting laryngospasm as the most common reason (30.4%). Nineteen nurses completed the SA survey and reported high satisfaction. Conclusion: This project successfully increased the utilization of a rapid response protocol in a pediatric perioperative setting using improvement methodologies and a simulation-based educational program.
RESUMO
Objective: The primary aim of this study was to apply a novel technology acceptance model (TAM) for virtual reality (VR) in healthcare. The secondary aim was to assess reliability of this model to evaluate factors that predict the intentions of pediatric health providers' use of VR as an anxiolytic for hospitalized pediatric patients. Materials and Methods: Healthcare providers that interacted with pediatric patients participated in a VR experience available as anxiolysis for minor procedures and then completed a survey evaluating attitudes, behaviors, and technology factors that influence adoption of new technologies. Results: Reliability for all domain measurements were good, and all confirmatory factor analysis models demonstrated good fit. Usefulness, ease of use, curiosity, and enjoyment of the VR experience all strongly predict intention to use and purchase VR technologies. Age of providers, past use, and cost of technology did not influence future purchase or use, suggesting that VR technologies may be broadly adopted in the pediatric healthcare setting. Discussion: Previous VR-TAM models in non-healthcare consumers formulated that age, past use, price willing to pay, and curiosity impacted perceived ease of use. This study established that age, past use, and cost may not influence use in healthcare. Future studies should be directed at evaluating the social influences and facilitating conditions within healthcare that play a larger influence on technology adoption. Conclusion: The VR-TAM model demonstrated validity and reliability for predicting intent to use VR in a pediatric hospital.
