Feasibility and Acceptability of Biofeedback-Based Virtual Reality System Use in Children and Adolescents Undergoing Surgery: Phase 1 of a Pilot 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 (BF), VR-BF is delivered through a gamified virtual reality environment, increasing the accessibility of BF. 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 has been established. OBJECTIVE: The primary objective was to develop a clinical trial protocol for VR-BF use in the pediatric perioperative setting, including preoperative education/training and postoperative application of VR-BF in children undergoing surgery. A secondary objective was to evaluate the patient/parent experience with VR-BF. METHODS: A total of 23 patients (12-18 years of age) scheduled for surgery at Nationwide Children's Hospital were recruited using purposive sampling. Following training, participants independently completed a daily, 10-minute VR-BF session for seven days before surgery and during their inpatient stay. Participants could use VR-BF up to two weeks after hospital discharge. Patient and session-level data of VR-BF usage and achievement of target HRV parameters were measured to identify the optimal frequency and duration of sessions before and after surgery for this population. Standardized questionnaires and semi-structured interviews were conducted to obtain qualitative information about patients' experiences with VR-BF. RESULTS: Patient-level data indicated that the highest odds of achieving 1 session under target HRV parameters was after 4 sessions (OR 4 vs. 3 sessions=5.1, 95% CI 1.3-20.6; OR 3 vs. 2 sessions=16.6, 95% CI 1.2-217.0). Session-level data showed that a session duration of 9 to 10 minutes provided the greatest odds of achieving 1 session under target HRV parameters (OR 9 vs. 8 minutes=1.3, 95% CI 1.1-1.7; OR 8 vs. 7 minutes=1.4, 95% CI 1.1-1.8; OR 10 vs. 9 minutes=1.0, 95% CI 0.9-1.2). Qualitative data revealed patient satisfaction with the VR-BF technology, particularly in managing perioperative stress (n=17, 85%). Few patients reported VR-BF as beneficial for pain (n=8, 40%). CONCLUSIONS: Children and adolescents undergoing surgery successfully learned behavioral strategies with VR-BF with once-daily 10-minute sessions for 5 days. To integrate VR-BF as a therapeutic intervention in a subsequent clinical trial, patients will be instructed to complete three 10-minute sessions a day for 7 days after surgery.

Use of high-flow nasal cannula versus other noninvasive ventilation techniques or conventional oxygen therapy for respiratory support following pediatric cardiac surgery: A systematic review and meta-analysis.

INTRODUCTION: Noninvasive respiratory support may be provided to decrease the risk of postextubation failure following surgery. Despite these efforts, approximately 3%-27% of infants and children still experience respiratory failure after tracheal extubation following cardiac surgery. This systematic review evaluates studies comparing the efficacy of high-flow nasal cannula to conventional oxygen therapy such as nasal cannula and other noninvasive ventilation techniques in preventing postextubation failure in this patient population. METHODS: A systematic and comprehensive search was conducted in major databases including MEDLINE, EMBASE, Web of Science, and Central. The search encompassed articles focusing on the prophylactic use of high-flow nasal cannula following tracheal extubation in pediatric patients undergoing cardiac surgery for congenital heart disease. The inclusion criteria for this review consisted of randomized clinical trials as well as observational, cohort, and case-control studies. RESULTS: A total of 1295 studies were screened and 12 studies met the inclusion criteria. These 12 studies included a total of 1565 children, classified into three groups: seven studies compared high-flow nasal cannula to noninvasive ventilation techniques, four studies compared high-flow nasal cannula to conventional oxygen therapy, and one observational single-arm study explored the use of high-flow nasal cannula with no control group. There was no significant difference in the incidence of tracheal reintubation between high-flow nasal cannula and conventional oxygen therapy (risk ratio [RR] = 0.67, 95% confidence interval [CI]: 0.24-1.90, p = .46). However, there was a lower incidence of tracheal reintubation in patients who were extubated to high-flow nasal cannula versus those extubated to noninvasive ventilation techniques (RR = 0.45, 95% CI: 0.32-0.63, p < .01). The high-flow nasal cannula group also demonstrated a lower mortality rate compared to the noninvasive ventilation techniques group (RR = 0.31, 95% CI: 0.16-0.61, p < .01) as well as a shorter postoperative length of stay (mean difference = -8.76 days, 95% CI: -13.08 to -4.45, p < .01) and shorter intensive care length of stay (mean difference = -4.63 days, 95% CI: -9.16 to -0.11, p = .04). CONCLUSION: High-flow nasal cannula is more effective in reducing the rate of postextubation failure compared to other forms of noninvasive ventilation techniques following surgery for congenital heart disease in pediatric-aged patients. high-flow nasal cannula is also associated with lower mortality rates and shorter length of stay. However, when comparing high-flow nasal cannula to conventional oxygen therapy, the findings were inconclusive primarily due to a limited number of scientific studies available on this specific comparison. Future study is needed to further define the benefit of high-flow nasal cannula compared to conventional oxygen therapy and various types of noninvasive ventilation techniques.

Impact of opioid law on prescriptions and satisfaction of pediatric burn and orthopedic patients: An epidemiologic study.

OBJECTIVES: The objective of this study was to determine the reduction in prescribed opioid pain dosage units to pediatric patients experiencing acute pain and to assess patient satisfaction with pain control 90-day post discharge following the 2017 Ohio opioid prescribing cap law. METHODS: The retrospective chart review included 960 pediatric (age 0-18 years) burn injury and knee arthroscopy patients treated between August 1, 2015-August 31, 2019. Prospectively, legal guardians completed a survey for a convenience sample of 50 patients. Opioid medications (days and morphine milligram equivalents (MMEs)/kg) prescribed at discharge before and after the Ohio law implementation were collected. Guardians reported experience and satisfaction with their child's opioid prescription at 90-days post discharge. RESULTS: From pre-law to post-law, there was a significant decrease (p<0.001) within the burn and knee cohorts in the median days (1.7 to 1.0 and 5.0 to 3.8, respectively) and median total MMEs prescribed (15.0 to 2.5 and 150.0 to 90.0, respectively). An interrupted time series analysis revealed a statistically significant decrease in MMEs/kg and days prescribed at discharge when the 2017 Ohio opioid prescription law went into effect, with an abrupt level change. Prospectively, more than half of participants were satisfied (72% burn and 68% knee) with their pain control and felt they received the right amount of medication (84% burn and 56% knee). Inpatient opioid use was not changed pre- and post-law. CONCLUSIONS: Discharge opioids prescribed for pediatric burn and knee arthroscopy procedures has decreased from 2015-2019. Caregivers varied greatly in their satisfaction with pain control and the amount of opioid prescribed.

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. This study assessed the impact of behavioral economic strategies versus a standard biological approach to recruit children into a randomized clinical trial assessing a biofeedback-based virtual reality intervention for postoperative pain management. We hypothesized the behavioral economics-informed approach would increase enrollment into the future trial, intention to adhere to therapy, acceptability of the intervention, and perceived efficacy while decreasing perception of treatment burden and risk. METHODS: This single-center, prospective, randomized trial recruited patients 12-18 years old undergoing surgery requiring postoperative admission and narcotic administration. Patient-parent dyads were randomized to watch a behavioral economics-informed (n = 64) or standard biological (n = 66) recruitment video about a study designed to assess impact of a virtual reality pain management intervention. RESULTS: There was no difference in rates of intention to enroll in the study between groups (behavioral economics: 75%, control: 79%, p = 0.744) or in median response scores to questions regarding intention to adhere to therapy (4.0 [3.0, 4.0] vs. 4.0 [3.0, 4.0], p=0.084), acceptability of therapy (4.0 [3.0, 4.0] vs. 4.0 [3.0, 4.0], p = 0.376), perceptions of treatment burden (3.0 [3.0, 4.0] vs. 4.0 [3.0, 4.0], p=0.251), and efficacy (3.0 [3.0, 4.0] vs. 3.0 [3.0, 4.0], p = 0.914). Patients in the behavioral economics group were less likely to perceive risk associated with virtual reality versus the control group (behavioral economics: 2.0 [1.0, 2.0], control: 2.0 [2.0, 3.0], p = 0.023). DISCUSSION: A behavioral economics-informed video did not increase patients' intentions to enroll into a clinical trial assessing the impact of virtual reality intervention for postoperative pain management. CONCLUSION: Either approach would be sufficient for patient recruitment for this type of clinical trial since the overall intention to enroll rate was 77%.

Clinical experience with the use of inhaled isopropyl alcohol to treat nausea and vomiting: A narrative review.

Isopropyl alcohol (IA) is a colorless, flammable organic compound that has been used in the manufacturing process of a wide variety of industrial and household chemicals. Inhalation of its vapor has been noted to potentially have antiemetic effects, which may be useful in the treatment of postoperative nausea and vomiting (PONV). However, given the varied study protocols and endpoints assessing its efficacy as antiemetic, clinical trials have yielded mixed results. If effective, inhalation of IA may be a cost-effective, readily available, and inexpensive therapy that can be used for the treatment of PONV with a low risk of adverse effects. The following narrative review explores the available information regarding the mechanism of action of IA in treating PONV, presents clinical information including possible mechanism of action and clinical applications, and reviews the published literature on its efficacy to treat nausea and vomiting with a focus on its use postoperatively. While early studies suggested that inhaled IA may be successful for the short-term treatment of PONV compared with placebo, subsequent studies both in and out of the operating room (OR) have reported conflicting results. In general, studies in the perioperative setting have provided some evidence to support the use of inhaled IA in alleviating or reducing the severity of PONV in adults. In particular, inhaled IA may have a more rapid onset compared with traditional antiemetic agents, but the clinical effect has generally been found to be short-lived. The results outside of the OR and perioperative setting have been somewhat more favorable, generally showing that inhaled IA reduces nausea and vomiting of various etiologies in adults in the emergency department setting. Similarly, it has been shown to reduce the need for rescue antiemetic agents in this area and thus may be considered a cost-cutting strategy with no reported adverse effects. The available literature suggests that inhaled IA may be considered a potential therapy to achieve rapid relief of PONV and assist in the management of nausea and vomiting in adult patients outside of the perioperative setting. There remain insufficient data to determine how inhaled IA may impact PONV in children. Given the mixed results and the limitations of the current studies, additional data are needed to draw firm conclusions regarding the utility of inhaled IA.

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]. For example, slow breathing increases heart rate variability (HRV) [9] to reduce pain through the downregulation of the sympathetic nervous system [10,11]. However, barriers to widespread use, such as the need for trained personnel and high costs of direct intervention, have hindered its widespread clinical use and access to this therapy [5,12]. VR-BF has not yet been integrated into perioperative care, and as such, no defined treatment protocols for preoperative training and postoperative application of VR-BF exist, particularly in children. The dataset presented in this article may help fill the unmet, critical need for accessible, effective, alternative therapeutic options for reducing postoperative pain and opioid exposure in children. This investigation aimed to establish measurable outcomes impacting a perioperative treatment protocol of VR-BF, a novel VR-based therapy that teaches patients relaxation techniques and monitors the sensitivity of heart rate variability (HRV) to different frequencies and durations of VR-BF sessions. Achievement of target physiological parameters, including HRV, was measured in children and adolescents undergoing surgery anticipated to cause moderate to severe pain (e.g., orthopedic, chest) requiring postoperative pain management by the Acute Pain Services at Nationwide Children's Hospital (NCH). This dataset included 23 surgical patients evaluated quantitatively and qualitatively to refine a treatment protocol for the feasibility and acceptability of (a) preoperative education and training in relaxation, and (b) postoperative application of a VR-BF intervention for pain management [13]. Qualitative data was collected using an investigator-derived questionnaire to obtain feedback and understand the patient and family experience using VR-BF. Descriptive statistics (mean±SD or median with interquartile range [IQR] for continuous variables; frequencies and percentages for categorical variables) and exploratory spline regression analyses were generated to define measurable outcomes for a future pilot, randomized clinical trial protocol.

Vial-splitting and Repackaging into Aliquot-specific Syringes: A Cost-effective and Waste-decreasing Strategy for Sugammadex.

Sugammadex is a medication that may have cost considerations with the potential for waste of unused product in pediatric patients due to the vial size and its single-use limitation. Therefore, exploring the potential of vial-splitting for perioperative use may be beneficial. Methods: The study was a retrospective, quality improvement study using the electronic medical record to identify every sugammadex administration over the last five years in a tertiary care pediatric institution. We divided patients into groups depending on the dose of sugammadex administered. The cost of sugammadex was calculated under three scenarios: (1) only 200-mg vials available; (2) 100-mg aliquots available; and (3) 50-mg aliquots. We then calculated the total money spent per patient in the 3 scenarios. Results: 31,063 patients received sugammadex over the study period, of whom 23.6% received 151-200 mg. The greatest percentage of patients received ≤50 mg (32.9%). The average cost per patient was $113.58, $81.61, and $68.83 if 200 mg, 100 mg, and 50 mg doses were available, respectively. Over the last 5 years, $1,390,110.13 could have been saved by having 50 and 100 mg aliquots available. Conclusions: Pediatric patients generally receive lower doses of sugammadex due to weight-based dosing, leading to increased waste and cost when using only 200-mg vials. Vial-splitting into smaller aliquots can significantly cut costs for healthcare centers and patients while decreasing waste.

Beyond mortality: definitions and benchmarks of outcome standards in paediatric anaesthesiology.

PURPOSE OF REVIEW: The aim of this study was to review the evolution of safety and outcomes in paediatric anaesthesia, identify gaps in quality and how these gaps may influence outcomes, and to propose a plan to address these challenges through the creation of universal outcome standards and a paediatric anaesthesia designation programme. RECENT FINDINGS: Tremendous advancements in the quality and safety of paediatric anaesthesia care have occurred since the 1950 s, resulting in a near absence of documented mortality in children undergoing general anaesthesia. However, the majority of data we have on paediatric anaesthesia outcomes come from specialized academic institutions, whereas most children are being anaesthetized outside of free-standing children's hospitals. SUMMARY: Although the literature supports dramatic improvements in patient safety during anaesthesia, there are still gaps, particularly in where a child receives anaesthesia care and in quality outcomes beyond mortality. Our goal is to increase equity in care, create standardized outcome measures in paediatric anaesthesia and build a verification system to ensure that these targets are accomplished. The time has come to benchmark paediatric anaesthesia care and increase quality received by all children with universal measures that go beyond simply mortality.

Paediatric pain management: from regional to virtual.

PURPOSE OF REVIEW: Due to increased interest in opioid-sparing multimodal analgesic strategies both inside and outside of the operating room, anaesthesiologists have started to look towards regional anaesthesia as well as nonpharmacological pain-reducing techniques. The purpose of this article is to discuss current trends and recent developments in regional anaesthesia and virtual reality for paediatric pain management. RECENT FINDINGS: The development of novel fascial plane blocks has expanded regional options for anaesthesiologists, especially when neuraxial anaesthesia is not a viable or straightforward option. Other regional techniques, such as spinal anaesthesia and continuous epidural analgesia for infants and neonates, are becoming more popular, as more paediatric anaesthesiologists become familiar with these techniques. Virtual reality for paediatric pain management is a relatively new area of study that has shown promise, but more research needs to be done before widespread adoption of this practice becomes a reality. Various preexisting pain-reducing strategies such as distraction and biofeedback are being integrated with virtual reality to help optimize its effect on pain and anxiety for paediatric patients. SUMMARY: Regional anaesthesia and virtual reality are valuable tools that serve to alleviate pain in paediatric patients. Advances are being made within both fields in various healthcare settings for different types of pain. Over the next few years, they will likely both play an increasing role in paediatric pain management.

The role of local inflammation in complications associated with intubation in pediatric patients: A narrative review.

Although the most important primary local inflammatory response factor to intubation is not yet clear, it is known that it may be directly attributed to the presence of trauma during intubation or the response of oral bacterial flora present in the trachea. It is known that prolonged intubation is associated with worse outcomes, but other underlying systemic issues, such as sepsis and trauma, are also associated with this result. Likewise, patients who require advanced airway management and excessive manipulation are more likely to experience complications. There are various inflammatory mediators that are generated during orotracheal intubation, many of which can be considered targets for therapies to help reduce inflammation caused by intubation. However, there is little evidence on the management of the inflammatory response induced by orotracheal intubation in pediatric patients. Therefore, the aim of this narrative review is to highlight the intubation associated complications that can arise from poorly controlled inflammation in intubated pediatric patients, review the proposed pathophysiology behind this, and discuss the current treatments that exist. Finally, taking into account the discussion on pathophysiology, we describe the current therapies being developed and future directions that can be taken in order to create more treatment options within this patient population.

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. VR-BF has yet to be employed in perioperative care, and as such, no defined treatment protocol for VR-BF exists. The primary aim of this study is to assess the feasibility of the perioperative use of VR-BF in children and adolescents. The secondary aims are to assess the acceptability of VR-BF and to collect pilot efficacy data. METHODS AND ANALYSIS: This is a single-centre, randomised controlled pilot clinical trial. A total of 70 patients (12-18 years) scheduled for surgery anticipated to cause moderate to severe pain with ≥1 night of hospital admission will be randomised to one of two study arms (VR-BF or control). Participants randomised to VR-BF (n=35) will use the ForeVR VR platform to engage their breathing in gamified VR applications. Participants randomised to control (n=35) will interact with a pain reflection app, Manage My Pain. The primary outcome is feasibility of VR-BF use in adolescents undergoing surgery as assessed through recruitment, enrolment, retention and adherence to the protocol. Secondary outcomes are acceptability of VR-BF and pilot efficacy measures, including pain, anxiety and opioid consumption. ETHICS AND DISSEMINATION: The protocol was approved by the Nationwide Children's Hospital Institutional Review Board (IRB #STUDY00002080). Patient recruitment begins in March 2023. Written informed consent is obtained for all participants. All information acquired will be disseminated via scientific meetings and published in peer-reviewed journals. Data will be available per request and results will be posted on ClinicalTrials.gov. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT04943874).

Retrospective study comparing outcomes of multimodal epidural and erector spinae catheter pain protocols after pectus surgery.

INTRODUCTION: There are no optimal postoperative analgesia regimens for Nuss procedures. We compared the effectiveness of thoracic epidurals (EPI) and novel ambulatory erector spinae plane (ESP) catheters as part of multimodal pain protocols after Nuss surgery. METHODS: Data on demographics, comorbidities, perioperative details, length of stay (LOS), in hospital and post discharge pain/opioid use, side effects, and emergency department (ED) visits were collected retrospectively in children who underwent Nuss repair with EPI (N = 114) and ESP protocols (N = 97). Association of the group with length of stay (LOS), in hospital opioid use (intravenous morphine equivalents (MEq)/kg over postoperative day (POD) 0-2), and oral opioid use beyond POD7 was analyzed using inverse probability of treatment weighting (IPTW) with propensity scores, followed by multivariable regression. RESULTS: Groups had similar demographics. Compared to EPI, ESP had longer block time and higher rate of ketamine and dexmedetomidine use. LOS for ESP was 2 days IQR (2, 2) compared to 3 days IQR (3, 4) for EPI (p < 0.01). Compared to EPI, ESP group had higher opioid use (in MEq/kg) intraoperatively (0.32 (IQR 0.27, 0.36) vs. 0.28 (0.24, 0.32); p < 0.01) but lower opioid use on POD 0 (0.09 (IQR 0.04, 0.17) vs. 0.11 (0.08, 0.17); p = 0.03) and POD2 (0.00 (IQR 0.00, 0.00) vs. 0.04 (0.00, 0.06) ; p < 0.01). ESP group also had lower total in hospital opioid use (0.57 (IQR 0.42, 0.73) vs.0.82 (0.71, 0.91); p < 0.01), and shorter duration of post discharge opioid use (6 days (IQR 5,8) vs. 9 days (IQR 7,12) (p < 0.01). After IPTW adjustment, ESP continued to be associated with shorter LOS (difference -1.20, 95% CI: -1.38, -1.01, p < 0.01) and decreased odds for opioid use beyond POD7 (OR 0.11, 95% CI: 0.05, 0.24); p < 0.01). However, total in hospital opioid use in MEq/kg (POD0-2) was now similar between groups (difference -0.02 (95% CI: -0.09, -0.04); p = 0.50). The EPI group had higher incidence of emesis (29% v 4%, p < 0.01), while ESP had higher catheter malfunction rates (23% v 0%; p < 0.01) but both groups had comparable ED visits/readmissions. DISCUSSION/CONCLUSION: Compared to EPI, multimodal ambulatory ESP protocol decreased LOS and postoperative opioid use, with comparable ED visits/readmissions. Disadvantages included higher postoperative pain scores, longer block times and higher catheter leakage/malfunction. LEVELS OF EVIDENCE: Level III.

Association of Pre-procedural Anxiety With Procedure-Related Pain During Outpatient Pediatric Burn Care: A Pilot Study.

The relationship between preprocedural anxiety and pain is not clear but has the potential to change the way pediatric patients need to be cared for prior to burn procedures. Using results from our recent randomized clinical trial among outpatient burn patients (n = 90) aged 6-17 years, the objective of this subsequent analysis was to assess whether preprocedural anxiety was associated with self-reported and researcher-observed pain scores. Anxiety before the dressing change was assessed using an abbreviated State-Trait Anxiety Inventory for Children (range 6-21) and reported with 95% confidence intervals (CI). Self-reported pain was reported using a Visual Analog Scale (range 0-100) and observed pain was assessed using the Face, Legs, Activity, Cry, and Consolability-revised scale. Over half of patients (58.9%) reported mild anxiety (score < 12) and about 5% of patients reported severe anxiety (score > 16). Younger children (6-8 years) reported higher anxiety scores than older children (15-17 years), but the difference did not achieve statistical significance (mean = 12.7, 95% CI: 11.5 to 13.9, P = .09). Nonparametric spearman correlation indicated that anxiety score was significantly correlated with observed pain (P = .01) and self-reported overall pain neared statistical significance (P = .06). In the final logistic regression of reporting moderate-to-severe pain (pain score > 30), the association between anxiety scores and self-reported overall moderate-to-severe pain was statistically significant (P = .03) when adjusting for race, healing degree, and pain medication use within 6 hr prior to burn dressing care. This pilot study provides preliminary data showing that anxiety before outpatient pediatric burn dressing changes is significantly associated with self-reported overall moderate-to-severe pain.

Isoelectric Electroencephalography in Infants and Toddlers during Anesthesia for Surgery: An International Observational Study.

BACKGROUND: Intraoperative isoelectric electroencephalography (EEG) has been associated with hypotension and postoperative delirium in adults. This international prospective observational study sought to determine the prevalence of isoelectric EEG in young children during anesthesia. The authors hypothesized that the prevalence of isoelectric events would be common worldwide and associated with certain anesthetic practices and intraoperative hypotension. METHODS: Fifteen hospitals enrolled patients age 36 months or younger for surgery using sevoflurane or propofol anesthetic. Frontal four-channel EEG was recorded for isoelectric events. Demographics, anesthetic, emergence behavior, and Pediatric Quality of Life variables were analyzed for association with isoelectric events. RESULTS: Isoelectric events occurred in 32% (206 of 648) of patients, varied significantly among sites (9 to 88%), and were most prevalent during pre-incision (117 of 628; 19%) and surgical maintenance (117 of 643; 18%). Isoelectric events were more likely with infants younger than 3 months (odds ratio, 4.4; 95% CI, 2.57 to 7.4; P < 0.001), endotracheal tube use (odds ratio, 1.78; 95% CI, 1.16 to 2.73; P = 0.008), and propofol bolus for airway placement after sevoflurane induction (odds ratio, 2.92; 95% CI, 1.78 to 4.8; P < 0.001), and less likely with use of muscle relaxant for intubation (odds ratio, 0.67; 95% CI, 0.46 to 0.99; P = 0.046]. Expired sevoflurane was higher in patients with isoelectric events during preincision (mean difference, 0.2%; 95% CI, 0.1 to 0.4; P = 0.005) and surgical maintenance (mean difference, 0.2%; 95% CI, 0.1 to 0.3; P = 0.002). Isoelectric events were associated with moderate (8 of 12, 67%) and severe hypotension (11 of 18, 61%) during preincision (odds ratio, 4.6; 95% CI, 1.30 to 16.1; P = 0.018) (odds ratio, 3.54; 95% CI, 1.27 to 9.9; P = 0.015) and surgical maintenance (odds ratio, 3.64; 95% CI, 1.71 to 7.8; P = 0.001) (odds ratio, 7.1; 95% CI, 1.78 to 28.1; P = 0.005), and lower Pediatric Quality of Life scores at baseline in patients 0 to 12 months (median of differences, -3.5; 95% CI, -6.2 to -0.7; P = 0.008) and 25 to 36 months (median of differences, -6.3; 95% CI, -10.4 to -2.1; P = 0.003) and 30-day follow-up in 0 to 12 months (median of differences, -2.8; 95% CI, -4.9 to 0; P = 0.036). Isoelectric events were not associated with emergence behavior or anesthetic (sevoflurane vs. propofol). CONCLUSIONS: Isoelectric events were common worldwide in young children during anesthesia and associated with age, specific anesthetic practices, and intraoperative hypotension.

Setting a universal standard: Should we benchmark quality outcomes for pediatric anesthesia care?

Anesthesiology is a medical specialty well known for its work in patient safety, allowing the field to show a dramatic decrease in perioperative morbidity and mortality in both adults and children since the 1950s. Currently, anesthesia-related mortality is close to zero in healthy children, with deaths occurring primarily in children ASA physical status ≥4. Survival during anesthesia today represents the expectation and standard of care, rather than a marker of quality. Several programs and organizations have created measures to assess safety in pediatric anesthesia-yet none are universally accepted as safety metrics or bundled to evaluate specific aspects of care. In addition, collection of this nonstandardized data in individual centers requires a significant investment of resources and personnel limiting access to only large, "resource-rich" institutions. In this perspective paper, we provide an overview of the efforts made to enhance quality of care across medical specialties with a specific emphasis on pediatric anesthesiology. We discuss the need for standardization of metrics to establish targets and benchmarks for the delivery of high-quality care to children and adolescents mainly in North America. The time has come to move beyond mortality and establish universally accepted minimum outcome standards in pediatric anesthesia. We believe this will ultimately improve confidence in the quality of pediatric anesthesia care offered to children, no matter where they are receiving that care.

Role of sugammadex in the treatment of anaphylaxis due to rocuronium in children: Extrapolation from adult and animal reports.

Allergic reactions are generalized hypersensitivity processes triggered by different antigenic stimuli, resulting in the end effect of mast cell degranulation and adverse physiologic effects. During the perioperative period, the most commonly identified agents include antibiotics, neuromuscular blocking agents (rocuronium and succinylcholine), chlorhexidine, and iodinated dyes for radiologic imaging. Sugammadex is a novel agent for the reversal of neuromuscular blockade achieved with rocuronium or vecuronium. Its unique mechanism of action, whereby it encapsulates and forms a one-to-one complex with rocuronium, has led to its anecdotal use as an adjunct in the treatment of anaphylactic and anaphylactoid reactions following rocuronium. The current manuscript discusses the potential use of sugammadex in the treatment of allergic reactions following the administration of rocuronium, reviews previous anecdotal reports of its use in these scenarios, and provides recommendations for future care.
