Effect of dimethyl fumarate on mitochondrial metabolism in a pediatric porcine model of asphyxia-induced in-hospital cardiac arrest. Sci Rep 2024; 14:13852.

Abstract
Neurological and cardiac injuries are significant contributors to morbidity and mortality following pediatric in-hospital cardiac arrest (IHCA). Preservation of mitochondrial function may be critical for reducing these injuries. Dimethyl fumarate (DMF) has shown potential to enhance mitochondrial content and reduce oxidative damage. To investigate the efficacy of DMF in mitigating mitochondrial injury in a pediatric porcine model of IHCA, toddler-aged piglets were subjected to asphyxia-induced CA, followed by ventricular fibrillation, high-quality cardiopulmonary resuscitation, and random assignment to receive either DMF (30 mg/kg) or placebo for four days. Sham animals underwent similar anesthesia protocols without CA. After four days, tissues were analyzed for mitochondrial markers. In the brain, untreated CA animals exhibited a reduced expression of proteins of the oxidative phosphorylation system (CI, CIV, CV) and decreased mitochondrial respiration (p < 0.001). Despite alterations in mitochondrial content and morphology in the myocardium, as assessed per transmission electron microscopy, mitochondrial function was unchanged. DMF treatment counteracted 25% of the proteomic changes induced by CA in the brain, and preserved mitochondrial structure in the myocardium. DMF demonstrates a potential therapeutic benefit in preserving mitochondrial integrity following asphyxia-induced IHCA. Further investigation is warranted to fully elucidate DMF's protective mechanisms and optimize its therapeutic application in post-arrest care.

Abstract
OBJECTIVES Rapid response system (RRS) activations resulting in emergency transfers (ETs) and codes outside the ICU are associated with increased mortality and length of stay. We aimed to evaluate the patient and care team characteristics of RRS activations resulting in ETs and codes outside the ICU (together classified as "deterioration events") versus those that did not result in a deterioration event. METHODS For each RRS activation at our institution from 2019 to 2021, data were gathered on patient demographics and medical diagnoses, care team and treatment factors, and ICU transfer. Descriptive statistics, bivariate analyses, and multivariable logistic regression using a backward elimination model selection method were performed to assess potential risk factors for deterioration events. RESULTS Over the 3-year period, 1765 RRS activations were identified. Fifty-three (3%) activations were deemed acute care codes, 64 (4%) were noncode ETs, 921 (52%) resulted in nonemergent transfers to an ICU, and 727 (41%) patients remained in an acute care unit. In a multivariable model, any complex chronic condition (adjusted odds ratio, 6.26; 95% confidence interval, 2.83-16.60) and hematology/oncology service (adjusted odds ratio, 2.19; 95% confidence interval, 1.28-3.74) were independent risk factors for a deterioration event. CONCLUSIONS Patients with medical complexity and patients on the hematology/oncology service had a higher risk of deterioration events than other patients with RRS activations. Further analyzing how our hospital evaluates and treats these specific patient populations is critical as we develop targeted interventions to reduce deterioration events.

INFECTIOUS DISEASES & CLINICAL MICROBIOLOGY 2023; 5:251-256.

Abstract
A retropharyngeal abscess (RPA) in early childhood is not uncommon due to at-risk lymph nodes in this deep neck space and is typified by fever, odynophagia, and a constellation of respiratory manifestations. However, RPA is exceedingly rare in the neonatal subpopulation and not part of the usual differential diagnosis algorithm in this age range. Herein, we present a unique case of a previously healthy 5-week-old male infant with protracted "congestion" and difficulty in oral feeding, whose clinical course is confounded by intermittent, positional bradycardia and subsequent apnea. He was eventually diagnosed with a methicillin-resistant Staphylococcus aureus (MRSA) RPA, leading to concurrent vascular and airways compromise in the form of baroreceptor-mediated bradycardia from mass-effect carotid body compression. This clinical case is an important reminder that any infant with positional vital sign changes should prompt urgent and thorough investigation for extraordinary and otherwise uncommon pathophysiologic states. The case also highlights the power of multidisciplinary collaboration across multiple specialties and parental advocacy in unifying a diagnosis for rare pediatric illnesses.

Abstract
OBJECTIVE Cardiopulmonary resuscitation (CPR) after cardiac arrest (CA) is one of the main causes of capillary leakage syndrome (CLS). This study aimed to establish a stable CLS model following the CA and cardiopulmonary resuscitation (CA-CPR) model in Sprague-Dawley (SD) rats. METHODS We conducted a prospective, randomized, animal model study. All adult male SD rats were randomly divided into a normal group (group N), a sham operation group (group S), and a cardiopulmonary resuscitation group (group T). The SD rats of the three groups were all inserted with 24-G needles through their left femoral arteries and right femoral veins. In group S and group T, the endotracheal tube was intubated. In group T, CA induced by asphyxia (AACA) was caused by vecuronium bromide with the endotracheal tube obstructed for 8 min, and the rats were resuscitated with manual chest compression and mechanical ventilation. Preresuscitation and postresuscitation measurements, including basic vital signs (BVS), blood gas analysis (BG), routine complete blood count (CBC), wet-to-dry ratio of tissues (W/D), and the HE staining results after 6 h were evaluated. RESULTS In group T, the success rate of the CA-CPR model was 60% (18/30), and CLS occurred in 26.6% (8/30) of the rats. There were no significant differences in the baseline characteristics, including BVS, BG, and CBC, among the three groups (P>0.05). Compared with pre-asphyxia, there were significant differences in BVS, CBC, and BG, including temperature, oxygen saturation (SpO2), mean arterial pressure (MAP), central venous pressure (CVP), white blood cell count (WBC), hemoglobin, hematocrit, pH, pCO2, pO2, SO2, lactate (Lac), base excess (BE), and Na+ (P<0.05) after the return of spontaneous circulation (ROSC) in group T. At 6 h after ROSC in group T and at 6 h after surgery in groups N and S, there were significant differences in temperature, heart rate (HR), respiratory rate (RR), SpO2, MAP, CVP, WBC, pH, pCO2, Na+, and K+ among the three groups (P<0.05). Compared with the other two groups, the rats in group T showed a significantly increased W/D weight ratio (P<0.05). The HE-stained sections showed consistent severe lesions in the lung, small intestine, and brain tissues of the rats at 6 h after ROSC following AACA. CONCLUSION The CA-CPR model in SD rats induced by asphyxia could reproduce CLS with good stability and reproducibility.

Abstract
BACKGROUND Patient-centered outcomes beyond mortality such as institution-free days (IFD) are becoming increasingly relevant in critical care trials. METHODS We calculated IFD using three definitions which differed in the way death and censoring of after-hospital deaths were handled analysing data from adult patient databases admitted to four ICUs of North Brisbane, Australia. Differences in distribution of IFD using different definitions were explored with descriptive statistics and histograms. Six pre-specified variables (age, illness severity, comorbidities index, elective status, surgical/medical admission and treatment limitations) were assessed and reported as determinants of IFDs for the proposed definitions. RESULTS Data from 25,371 ICU admissions was analysed. The density distribution of IFD was bimodal with a peak at 0 days and a variable right-sided peak depending on the definition used. The mean IFD varied from 253 (standard deviation(SD) 151.3) to 295 (SD 116.2) depending on definition used. Multivariable zero-inflated negative binomial regression modelling showed that the six pre-specified variables had significant associations with IFD and their magnitude of effect varied with the definition used. CONCLUSIONS IFD is a simple, easily measurable patient-centered outcome that varies depending on the definition used. Patient input should be sought to define the optimum definition and clinical use of IFD.

Abstract
BACKGROUND Cardiac arrest is a leading cause of mortality prior to discharge for children admitted to the pediatric intensive care unit. To address this problem, we used machine learning to predict cardiac arrest up to three hours in advance. METHODS Our data consists of 240 Hz ECG waveform data, 0.5 Hz physiological time series data, medications, and demographics from 1,145 patients in the pediatric intensive care unit at the Johns Hopkins Hospital, 15 of whom experienced a cardiac arrest. The data were divided into training, validating, and testing sets, and features were generated every five minutes. 23 heart rate variability (HRV) metrics were determined from ECG waveforms. 96 summary statistics were calculated for 12 vital signs, such as respiratory rate and blood pressure. Medications were classified into 42 therapeutic drug classes. Binary features were generated to indicate the administration of these different drugs. Next, six machine learning models were evaluated: logistic regression, support vector machine, random forest, XGBoost, LightGBM, and a soft voting ensemble. RESULTS XGBoost performed the best, with 0.971 auROC, 0.797 auPRC, 99.5% sensitivity, and 69.6% specificity on an independent test set. CONCLUSION We have created high-performing models that identify signatures of in-hospital cardiac arrest (IHCA) that may not be evident to clinicians. These signatures include a combination of heart rate variability metrics, vital signs data, and therapeutic drug classes. These machine learning models can predict IHCA up to three hours prior to onset with high performance, allowing clinicians to intervene earlier, improving patient outcomes.

Abstract
Background Although the outcome of cardiopulmonary resuscitation (CPR) is still unsatisfactory, there are few studies about temporal trends of in-hospital CPR incidence and mortality. We aimed to evaluate nationwide trends of in-hospital CPR incidence and its associated risk factors and mortality in pediatric patients using a database of the Korean National Health Insurance between 2012 and 2018. Methods and Results We excluded neonates and neonatal intensive care unit admissions. Incidence of in-hospital pediatric CPR was 0.58 per 1000 admissions (3165 CPR/5 429 471 admissions), and the associated mortality was 50.4%. Change in CPR incidence according to year was not significant in an adjusted analysis (P=0.234). However, CPR mortality increased significantly by 6.6% every year in an adjusted analysis (P<0.001). Hospitals supporting pediatric critical care showed 37.7% lower odds of CPR incidence (P<0.001) and 27.5% lower odds of mortality compared with other hospitals in the adjusted analysis (P<0.001), and they did not show an increase in mortality (P for trend=0.882). Conclusions Temporal trends of in-hospital CPR mortality worsened in Korea, and the trends differed according to subgroups. Study results highlight the need for ongoing evaluation of CPR trends and for further CPR outcome improvement among hospitalized children.

Abstract
Cardiac arrest causes primary and secondary brain injuries. We evaluated the association between neuron-specific enolase (NSE), serum S-100B (S100B), electroencephalogram (EEG) patterns, and post-cardiac arrest outcomes in pediatric patients. A prospective observational study was conducted in the pediatric intensive care unit and included 41 post-cardiac arrest patients who underwent EEG and serum sampling for NSE and S100B. The participants were aged 1 month to 18 years who experienced cardiac arrest and underwent CPR after a sustained return of spontaneous circulation for ≥48 h. Approximately 19.5% (n = 8) of patients survived until ICU discharge. Convulsions and sepsis were significantly associated with higher mortality (relative risk: 1.33 [95% CI = 1.09-1.6] and 1.99 [95% CI = 0.8-4.7], respectively). Serum NSE and S100B levels were not statistically associated with the outcome (p = 0.278 and 0.693, respectively). NSE levels were positively correlated with the duration of CPR. EEG patterns were significantly associated with the outcome (p = 0.01). Non-epileptogenic EEG activity was associated with the highest survival rate. Post-cardiac arrest syndrome is a serious condition with a high mortality rate. Management of sepsis and convulsions affects prognosis. We believe that NSE and S100B may have no benefit in survival evaluation. EEG can be considered for post-cardiac arrest patients.

Shimoda-Sakano TM, Paiva EF, Schvartsman C, Reis AG. Factors associated with survival and neurologic outcome after in-hospital cardiac arrest in children: A cohort study. Resusc Plus 2023; 13:100354. [PMID: 36686327 PMCID: PMC9852640 DOI: 10.1016/j.resplu.2022.100354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2022] [Revised: 12/26/2022] [Accepted: 12/28/2022] [Indexed: 01/13/2023] Open
Abstract
Aim In-hospital paediatric cardiopulmonary resuscitation (CPR) survival has been improving in high-income countries. This study aimed to analyse factors associated with survival and neurological outcome after paediatric CPR in a middle-income country. Methods This observational study of in-hospital cardiac arrest using Utstein-style registry included patients <18 years old submitted to CPR between 2015 and 2020, at a high-complexity hospital. Outcomes were survival and neurological status assessed using Paediatric Cerebral Performance Categories score at prearrest, discharge, and after 180 days. Results Of 323 patients who underwent CPR, 108 (33.4%) survived to discharge and 93 (28.8%) after 180 days. In multivariable analysis, lower survival at discharge was associated with liver disease (OR 0.060, CI 0.007-0.510, p = 0.010); vasoactive drug infusion before cardiac arrest (OR 0.145, CI 0.065-0.325, p < 0.001); shock as the immediate cause (OR 0.183, CI 0.069-0.486, p = 0.001); resuscitation > 30 min (OR 0.070, CI 0.014-0.344, p = 0.001); and bicarbonate administration during CPR (OR 0.318, CI 0.130-0.780, p = 0.01). The same factors remained associated with lower survival after 180 days. Neurological outcome was analysed in the 93 survivors after 180 days following CPR. Prearrest neurological dysfunction was observed in 31.4%, and neurological prognosis was favourable in 79.7% at discharge and similar after 180 days. Conclusion In-hospital paediatric cardiac arrest patients with complex chronic conditions had lower survival associated with liver disease, shock as cause of cardiac arrest, vasoactive drug infusion before cardiac arrest, bicarbonate administration during CPR, and prolonged resuscitation. Most survivors had favourable neurological outcome.

Abstract
Child health is defined by a complex, dynamic network of genetic, cultural, nutritional, infectious, and environmental determinants at distinct, developmentally determined epochs from preconception to adolescence. This network shapes the future of children, susceptibilities to adult diseases, and individual child health outcomes. Evolution selects characteristics during fetal life, infancy, childhood, and adolescence that adapt to predictable and unpredictable exposures/stresses by creating alternative developmental phenotype trajectories. While child health has improved in the United States and globally over the past 30 years, continued improvement requires access to data that fully represent the complexity of these interactions and to new analytic methods. Big Data and innovative data science methods provide tools to integrate multiple data dimensions for description of best clinical, predictive, and preventive practices, for reducing racial disparities in child health outcomes, for inclusion of patient and family input in medical assessments, and for defining individual disease risk, mechanisms, and therapies. However, leveraging these resources will require new strategies that intentionally address institutional, ethical, regulatory, cultural, technical, and systemic barriers as well as developing partnerships with children and families from diverse backgrounds that acknowledge historical sources of mistrust. We highlight existing pediatric Big Data initiatives and identify areas of future research. IMPACT: Big Data and data science can improve child health. This review highlights the importance for child health of child-specific and life course-based Big Data and data science strategies. This review provides recommendations for future pediatric-specific Big Data and data science research.

Abstract
In-hospital pediatric cardiopulmonary arrest is rare. With more than 50% of patients not surviving to discharge following cardiopulmonary arrest, it is important that health-care providers (HCPs) respond appropriately to deteriorating patients. Our study evaluated the performance of basic life support skills using non-acute HCPs during pediatric inpatient resuscitation events. We conducted a retrospective chart review of all code blue team (CBT) activations in non-acute care areas of a tertiary care children's hospital from 2008 to 2017. The main outcomes were frequency of life support algorithmic assessments and interventions (critical actions) performed by non-acute HCPs prior to the arrival of CBT. CBT activation and outcome data were summarized descriptively. Logistic regression was used to assess for an association of outcomes with the presence of established leadership. A total of 60 CBT activations were retrieved, 48 of which had data available on isolated non-acute HCP performance. Most children (93%) survived to discharge. Critical action performance review revealed that an airway, breathing and pulse assessment was documented to have occurred in 33%, 69% and 29% of cases, respectively. A full primary assessment was documented in 6% of cases. The presence of established leadership was associated with the performance of a partial ABC assessment. Our results suggest that resuscitation performance of pediatric inpatient non-acute HCPs often does not adhere to standard life support guidelines. These results highlight the need to reconsider the current approaches used for non-acute HCP resuscitation training.

Abstract
OBJECTIVE Describe the epidemiology of deaths in children not submitted to CPR, compare to a CPR group and evaluate patients' medical records of those not submitted to CPR. METHODS Observational cross-sectional study assessing deaths between 2015 and 2018 in a pediatric tertiary hospital, divided into two groups: CPR and no- CPR. The source of data included the cardiorespiratory arrest register, based on Utstein style. Children's medical records in no-CPR group were researched by hand. RESULTS 241 deaths were included, 162 in CPR group and 79 in the no-CPR group. Preexisting diseases were observed in 98.3% of patients and prior advanced intervention in 78%. Of the 241 deaths, 212 (88%) occurred in the PICU, being 138/162 (85.2%) in CPR group and 74/79 (93.7%) in no-CPR group (p = 0.018). Bradycardia as the initial rhythm was five times more frequent in the CPR group (OR 5.06, 95% CI 1.94-13,19). There was no statistically significant difference regarding age, gender, preexisting diseases, and period of the day of the occurrence of death. Medical records revealed factors related to the family decision-making process or the suitability of therapeutic effort. Discrepancies between the practice of CPR and medical records were identified in 9/79 (11,4%) records allocated to the no-CPR group. CONCLUSION Most deaths with CPR and with the no-CPR occurred in the PICU. Bradycardia as the initial rhythm was five times more frequent in the CPR group. Medical records reflected the complexity of the decision not to perform CPR. Discrepancies were identified between practice and medical records in the no-CPR group.

Abstract
OBJECTIVE To explore the value of pediatric early warning scoring system (PEWS) in an emergency observation room in China. METHODS The children who had been admitted consecutively to the emergency observation room from Jan, 2019 to Aug, 2020 were selected. Three most important time-points including the first value (admission value), the highest value during the observation (highest value), and final value (discharge value) of Brighton Pediatric Early Warning Score (PEWS) was evaluated in all patients. RESULTS 4717 patients were included. They were categorized into 3 groups, namely, discharged group (G1, n = 2320), specialized ward group (G2, n = 2128), and ICU group (G3, n = 269). The different PEWS values of admission value, highest value, and discharge value were significantly different among the 3 groups (P<0.001). Highest value of G1 and G2 were significantly lower than that of G3 (P<0.001). AUROC curves of different PEWS values were used to predict the possibility of PICU admission and PICU mortality within 24 h of admission, and the values were 0.698, 0.878, 0.974 and 0.709, 0.883, 0.951, respectively. The cutoff values for PICU admission of 3 different PEWS values were 2.5 (sensitivity 0.635, specificity 0.699), 3.5 (sensitivity 0.817, specificity 0.9), 3.5 (sensitivity 0.837, specificity 0.985). The cutoff values for PICU mortality of 3 different PEWS values were 4 (sensitivity 0.625, specificity 0.799), 4.5 (sensitivity 0.722, specificity 0.79), 4.5 (sensitivity 0.883, specificity 0.987). The discharge value had the strongest prediction ability. CONCLUSIONS PEWS can be used for early identification and warning of critically ill children.

Abstract
OBJECTIVES Children with traumatic arrests represent almost one third of annual pediatric out-of-hospital cardiac arrests (OHCAs). However, traumatic arrests are often excluded from study populations because survival posttraumatic arrest is thought to be negligible. We hypothesized that children treated and transported by emergency medical services (EMS) personnel after traumatic OHCA would have lower survival compared with children treated after medical OHCA. METHODS We performed a secondary, observational study of children younger than 18 years treated and transported by 78 EMS agencies in southwestern Pennsylvania after OHCA from 2010 to 2014. Etiology was determined as trauma or medical by EMS services. We analyzed patient, cardiac arrest, and resuscitation characteristics and ascertained vital status using the National Death Index. We used multivariable logistic regression to test the association of etiology with mortality after covariate adjustment. RESULTS Forty eight of 209 children (23%) had traumatic OHCA. Children with trauma were older than those with medical OHCA (13.2 [3.8-15.9] vs 0.5 [0.2-2.4] years, P < 0.001). Prehospital return of spontaneous circulation frequency for trauma versus medical etiology was similar (90% vs 87%, P = 0.84). Patients with trauma had higher mortality (69% vs 45% P = 0.004). CONCLUSIONS More than 8 of 10 children with EMS treated and transported OHCA achieved return of spontaneous circulation. Despite lower survival rates than medical OHCA patients, almost one third of children with a traumatic etiology survived throughout the study period. Future research programs warrant inclusion of children with traumatic OHCA to improve outcomes.

Standard CPR versus interposed abdominal compression CPR in shunted single ventricle patients: comparison using a lumped parameter mathematical model. Cardiol Young 2022; 32:1122-1128.

Abstract
INTRODUCTION Cardiopulmonary resuscitation (CPR) in the shunted single-ventricle population is associated with poor outcomes. Interposed abdominal compression-cardiopulmonary resuscitation, or IAC-CPR, is an adjunct to standard CPR in which pressure is applied to the abdomen during the recoil phase of chest compressions. METHODS A lumped parameter model that represents heart chambers and blood vessels as resistors and capacitors was used to simulate blood flow in both Blalock-Taussig-Thomas and Sano circulations. For standard CPR, a prescribed external pressure waveform was applied to the heart chambers and great vessels to simulate chest compressions. IAC-CPR was modelled by adding phasic compression pressure to the abdominal aorta. Differential equations for the model were solved by a Runge-Kutta method. RESULTS In the Blalock-Taussig-Thomas model, mean pulmonary blood flow during IAC-CPR was 30% higher than during standard CPR; cardiac output increased 21%, diastolic blood pressure 16%, systolic blood pressure 8%, coronary perfusion pressure 17%, and coronary blood flow 17%. In the Sano model, pulmonary blood flow during IAC-CPR increased 150%, whereas cardiac output was improved by 13%, diastolic blood pressure 18%, systolic blood pressure 8%, coronary perfusion pressure 15%, and coronary blood flow 14%. CONCLUSIONS In this model, IAC-CPR confers significant advantage over standard CPR with respect to pulmonary blood flow, cardiac output, blood pressure, coronary perfusion pressure, and coronary blood flow. These results support the notion that single-ventricle paediatric patients may benefit from adjunctive resuscitation techniques, and underscores the need for an in-vivo trial of IAC-CPR in children.

Abstract
Background Mean circulatory filling pressure (Pmcf) provides information on stressed volume and is crucial for maintaining venous return. This study investigated the Pmcf and other determinants of venous return in dysrhythmic and asphyxial circulatory shock and arrest. Methods Twenty Landrace/Large-White piglets were allocated into two groups of 10 animals each. In the dysrhythmic group, ventricular fibrillation was induced with a 9 V cadmium battery, while in the asphyxia group, cardiac arrest was induced by stopping and disconnecting the ventilator and clamping the tracheal tube at the end of exhalation. Mean circulatory filling pressure was calculated using the equilibrium mean right atrial pressure at 5–7.5 s after the onset of cardiac arrest and then every 10 s until 1 min post-arrest. Successful resuscitation was defined as return of spontaneous circulation (ROSC) with a MAP of at least 60 mmHg for a minimum of 5 min. Results After the onset of asphyxia, a ΔPmca increase of 0.004 mmHg, 0.01 mmHg, and 1.26 mmHg was observed for each mmHg decrease in PaO2, each mmHg increase in PaCO2, and each unit decrease in pH, respectively. Mean Pmcf value in the ventricular fibrillation and asphyxia group was 14.81 ± 0.5 mmHg and 16.04 ± 0.6 mmHg (p < 0.001) and decreased by 0.031 mmHg and 0.013 mmHg (p < 0.001), respectively, for every additional second passing after the onset of cardiac arrest. With the exception of the 5–7.5 s time interval, post-cardiac arrest right atrial pressure was significantly higher in the asphyxia group. Mean circulatory filling pressure at 5 to 7.5 s after cardiac arrest predicted ROSC in both groups, with a cut-off value of 16 mmHg (AUC = 0.905, p < 0.001). Conclusion Mean circulatory filling pressure was higher in hypoxic hypercapnic conditions and decreased at a lower rate after cardiac arrest compared to normoxemic and normocapnic state. A Pmcf cut-off point of 16 mmHg at 5–7.5 s after cardiac arrest can highly predict ROSC.

Abstract
AIM To investigate how combined electrographic and radiologic data inform outcomes in children after cardiac arrest. METHODS Retrospective observational study of children admitted to the pediatric intensive care unit (PICU) of a tertiary children's hospital with diagnosis of cardiac arrest from 2009 to 2016. The first 20 min of electroencephalogram (EEG) background was blindly scored. Presence and location of magnetic resonance imaging (MRI) diffusion-weighted image (DWI) abnormalities were correlated with T2-weighted signal. Outcomes were categorized using Pediatric Cerebral Performance Category (PCPC) scores at hospital discharge, with "poor outcome" reflecting a PCPC score of 4-6. Logistic regression models examined the association of EEG and MRI variables with outcome. RESULTS 41 children met inclusion criteria and had both post-arrest EEG monitoring within 72 hours after ROSC and brain MRI performed within 8 days. Among the 19 children with poor outcome, 10 children did not survive to discharge. Severely abnormal EEG background (p < 0.0001) and any diffusion restriction (p < 0.0001) were associated with poor outcome. The area under the ROC curve (AUC) for identifying outcome based on EEG background alone was 0.86, which improved to 0.94 with combined EEG and MRI data (p = 0.02). CONCLUSION Diffusion abnormalities on MRI within 8 days after ROSC add to the prognostic value of EEG background in children surviving cardiac arrest.

Abstract
OBJECTIVES The pediatric resuscitation guidelines recommend the use of 0. 01 mg kg-1 epinephrine during a cardiac arrest; an epinephrine dose higher than that is not recommended. The first aim of this study was to determine the administration rate of high epinephrine dose during pediatric out-of-hospital cardiac arrest. The second aim was to compare the survival status in patients who received high or standard doses of epinephrine. METHODS This was a multicenter comparative post-hoc study conducted between January 2011 and July 2021 based on the French National Cardiac Arrest Registry data. All prepubescent (boys < 12 years old, girls < 10 years old) victims of an out-of-hospital cardiac arrest were included. To compare survival status and control bias, patients who received a high epinephrine dose were matched with those who received a standard epinephrine dose using propensity score matching. RESULTS The analysis included 755 patients; 400 (53%) received a high dose and 355 (47%) received a standard dose of epinephrine. The median dose (mg kg-1) per bolus was higher in the high-dose group than that in the standard dose group (0.04 vs. 0.01 mg kg-1, P < 0.001). Before matching, there was no between-group difference in the 30-day survival rate or survival status at hospital discharge. Matching yielded 288 pairs; there was no between-group difference in the 30-day survival rate or survival at hospital discharge (High dose, n = 5; standard dose, n = 12; Odds ratios: 2.40, 95% confidence interval: 0.85-6.81). Only 2 patients in the standard dose group had a good neurological outcome. CONCLUSION More than 50% of the patients did not receive the recommended epinephrine dose during resuscitation. There was no association between patients receiving a high dose or standard dose of epinephrine with the 30-day survival or survival status at hospital discharge. Collaboration across multiple cardiac arrest registries is needed to study the application of pediatric guidelines.

Abstract
OBJECTIVE To investigate the epidemiology and the effectiveness of resuscitation from cardiopulmonary arrest (CPA) among critically ill children and adolescents during pediatric intensive care unit (PICU) stay across China. METHODS A prospective multicenter study was conducted in 11 PICUs in tertiary hospitals. Consecutively hospitalized critically ill children, from 29-day old to 18-year old, who had suffered from CPA and required cardiopulmonary resuscitation (CPR) in the PICU were enrolled (December 2017-October 2018). Data were collected and analyzed using the "in-hospital Utstein style." Neurological outcome was assessed with the Pediatric Cerebral Performance Category (PCPC) scale among children who had survived. Factors associated with the return of spontaneous circulation (ROSC) and survival at discharge were evaluated using multivariate logistic regression. RESULTS Among 11,599 admissions to PICU, 372 children (3.2%) had CPA during their stay; 281 (75.5%) received CPR, and 91 (24.5%) did not (due to an order of "Do Not Resuscitate" requested by their guardians). Cardiopulmonary disease was the most common reason for CPA (28.1% respiratory and 19.6% circulatory). The most frequent initial dysrhythmia was bradycardia (79%). In total, 170 (60.3%) of the total children had an ROSC, 91 had (37.4%) survived till hospital discharge, 28 (11.5%) had survived 6 months, and 19 (7.8%) had survived for 1 year after discharge. Among the 91 children who were viable at discharge, 47.2% (43/91) received a good PCPC score (1-3). The regression analysis results revealed that the duration of CPR and the dose of epinephrine were significantly associated with ROSC, while the duration of CPR, number of CPR attempts, ventricular tachycardia/ventricular fibrillation (VT/VF), and the dose of epinephrine were significantly associated with survival at discharge. CONCLUSION The prevalence of CPA in critically ill children and adolescents is relatively high in China. The duration of CPR and the dose of epinephrine are associated with ROSC. The long-term prognosis of children who had survived after CPR needs further improvement.

Abstract
In the pediatric intensive care unit (PICU), cardiac arrest (CA) is rare but results in high rates of morbidity and mortality. A retrospective chart review of 223 patients who suffered from in-PICU CA was analyzed from January 2017 to December 2020. Outcomes at discharge were evaluated using pediatric cerebral performance category (PCPC). Return of spontaneous circulation was attained by 167 (74.8%) patients. In total, only 58 (25%) patients survived to hospital discharge, and 49 (21.9%) of the cohort had good neurologic outcomes. Based on multivariate logistic regression analysis, vasoactive-inotropic drug usage before CA, previous PCPC scale >2, underlying hemato-oncologic disease, and total time of CPR were risk factors associated with poor outcomes. Furthermore, we determined the cutoff value of duration of CPR in predicting poor neurologic outcomes and in-hospital mortality in patients caused by in-PICU CA as 17 and 23.5 min respectively.

Abstract
BACKGROUND Our objective was to assess the association between intensive care unit (ICU)-free days and patient outcomes in pediatric prehospital care and to evaluate whether ICU-free days is a more sensitive outcome measure for emergency medical services research in this population. METHODS This study used data from a previous pediatric prehospital trial. The original study enrolled patients ≤12 years of age and compared bag-valve-mask-ventilation (BVM) versus endotracheal intubation (ETI) during prehospital resuscitation. For the current study, we defined ICU-free days as 30 minus the number of days in the ICU (range, 0-30 days) and assigned 0 ICU-free days for death within 30 days. We compared ICU-free days between the original study treatment groups (BVM vs ETI) and with the original trial outcomes of survival to hospital discharge and Pediatric Cerebral Performance Category (PCPC). RESULTS Median ICU-free days for the BVM group (n = 404) versus ETI group (n = 416) was not statistically different: 0 ICU-free days (interquartile range, 0-10) versus 0 (0-0), P = 0.219. Median ICU-free days were greater for BVM group in 3 subgroups: foreign body aspiration 30 (0-30) versus 0 (0-21), P = 0.028; child maltreatment 0 (0-14.2) versus 0 (0-0), P = 0.004; and respiratory arrest 25 (1-29) versus 7.5 (0-27.7), P = 0.015. In the original trial, neither survival nor PCPC demonstrated differences in all 3 subgroups-survival was greater with BVM for child maltreatment and respiratory arrest and favorable PCPC was greater with BVM for foreign body aspiration. Overall, in the current study, patients with more ICU-free days also had greater survival to hospital discharge and more favorable PCPC scores. CONCLUSIONS This initial study of the association between ICU-free days and patient outcomes during prehospital pediatric resuscitation appears to support the use of ICU-free days as a clinical endpoint in this population. ICU-free days may be more sensitive than either mortality or PCPC alone while capturing aspects of both measures.

PediAppRREST: effectiveness of an interactive cognitive support tablet app in reducing deviations from guidelines in the management of paediatric cardiac arrest: protocol for a simulation-based randomised controlled trial. BMJ Open 2021; 11:e047208.

Abstract
INTRODUCTION Paediatric cardiac arrest (PCA), despite its low incidence, has a high mortality. Its management is complex and deviations from guideline recommendations occur frequently. We developed a new interactive tablet app, named PediAppRREST, to support the management of PCA. The app received a good usability evaluation in a previous pilot trial. The aim of the study is to evaluate the effectiveness of the PediAppRREST app in reducing deviations from guideline recommendations in PCA management. METHODS AND ANALYSIS This is a multicentre, simulation-based, randomised controlled, three-parallel-arm study. Participants are residents in Paediatric, Emergency Medicine, and Anaesthesiology programmes in Italy. All 105 teams (315 participants) manage the same scenario of in-hospital PCA. Teams are randomised by the study statistician into one of three study arms for the management of the PCA scenario: (1) an intervention group using the PediAppRREST app or (2) a control group Paediatric Advanced Life Support (CtrlPALS+) using the PALS pocket reference card; or (3) a control group (CtrlPALS-) not allowed to use any PALS-related cognitive aid. The primary outcome of the study is the number of deviations (delays and errors) in PCA management from PALS guideline recommendations, according to a novel checklist, named c-DEV15plus. The c-DEV15plus scores will be compared between groups with a one-way analysis of variance model, followed by the Tukey-Kramer multiple comparisons adjustment procedure in case of statistical significance. ETHICS AND DISSEMINATION The Ethics Committee of the University Hospital of Padova, coordinating centre of the trial, deemed the project to be a negligible risk study and approved it through an expedited review process. The results of the study will be disseminated in peer-reviewed journals, and at national and international scientific conferences. Based on the study results, the PediAppRREST app will be further refined and will be available for download by institutions/healthcare professionals. TRIAL REGISTRATION NUMBER NCT04619498; Pre-results.

Abstract
Background Amplitude spectral area (AMSA) predicts termination of fibrillation (TOF) with return of spontaneous circulation (ROSC) and survival in adults but has not been studied in pediatric cardiac arrest. We characterized AMSA during pediatric cardiac arrest from a Pediatric Resuscitation Quality Collaborative and hypothesized that AMSA would be associated with TOF and ROSC. Methods and Results Children aged <18 years with cardiac arrest and ventricular fibrillation were studied. AMSA was calculated for 2 seconds before shock and averaged for each subject (AMSA‐avg). TOF was defined as termination of ventricular fibrillation 10 seconds after defibrillation to any non‐ventricular fibrillation rhythm. ROSC was defined as >20 minutes without chest compressions. Univariate and multivariable logistic regression analyses controlling for weight, current, and illness category were performed. Primary end points were TOF and ROSC. Secondary end points were 24‐hour survival and survival to discharge. Between 2015 and 2019, 50 children from 14 hospitals with 111 shocks were identified. In univariate analyses AMSA was not associated with TOF and AMS‐Aavg was not associated with ROSC. Multivariable logistic regression showed no association between AMSA and TOF but controlling for defibrillation average current and illness category, there was a trend to significant association between AMSA‐avg and ROSC (odds ratio, 1.10 [1.00‒1.22] P=0.058). There was no significant association between AMSA‐avg and 24‐hour survival or survival to hospital discharge. Conclusions In pediatric patients, AMSA was not associated with TOF, whereas AMSA‐avg had a trend to significance for association in ROSC, but not 24‐hour survival or survival to hospital discharge.

Abstract
OBJECTIVES The Pediatric Early Warning Score (PEWS) is an evidence-based tool that allows early collaborative assessment and intervention for a rapid response team (RRT) activation. The goal of our quality improvement initiative was to reduce the percentage of unnecessary RRT activations by 50% over 2 years without increasing PICU transfers or compromising patient safety and timely evaluation. METHODS A PEWS system replaced preexisting vital signs-based pediatric RRT criteria and was modified through plan-do-study-act cycles. Unnecessary RRT activations, total RRT activation rate, transfers to the PICU, total clinical interventions performed per RRT, and missed RRT activation rate were compared between intervention periods. Likert scale surveys were administered to measure satisfaction with each modification. RESULTS There was a significant decrease in the percentage of unnecessary RRT activations from 33% to 3.5% after the implementation of the PEWS and modified-PEWS systems (P < .05). The RRT activation rate decreased from 22.6 to 13.3 RRT activations per 1000 patient care days after implementation of the PEWS and modified-PEWS systems (P < .05), without changes in PICU transfer rates. Physicians reported that the PEWS system improved nursing communication and accuracy of RRT criteria (P < .05). Nursing reported that the PEWS system improved patient management and clinical autonomy (P < .05). CONCLUSIONS The PEWS systems have been an effective means of identifying deteriorating pediatric patients and reducing unnecessary RRT activations. The new system fosters collaboration and communication at the bedside to prevent acute deterioration, perform timely interventions, and ultimately improve patient safety and outcomes.

Abstract
OBJECTIVES We examined a large single-institution experience in extracorporeal cardiopulmonary resuscitation (ECPR) in children having cardiac arrest refractory to conventional resuscitation measures with focus on factors affecting survival. METHODS Between 2002 and 2017, 184 children underwent ECPR at our institution. We entered demographic, anatomic, clinical, surgical, and ECPR support details into a multivariable logistic regression models to determine factors associated with mortality. RESULTS Median age was 54 days (interquartile range [IQR]: 11-272). In all, 157 (85%) patients had primary cardiac disease, including 136 (74%) with congenital heart disease (71 with single ventricle). Extracorporeal cardiopulmonary resuscitation occurred following cardiac surgery in 124 (67%) patients. Median cardiopulmonary resuscitation (CPR) duration was 27 minutes (IQR: 18-40) and median support duration was 3.0 days (IQR: 1.6-5.3). Overall, ECPR was weaned in 115 (63%), with 79 (43%) surviving to hospital discharge. Survival for patients with congenital heart disease, noncongenital cardiac, and noncardiac pathologies was 44%, 71%, and 15%, respectively. On multivariable regression analysis, risk factors associated with mortality were presupport pH <7.1 (odds ratio [OR] = 3.7, 95% confidence interval [CI]: 1.11-12.41, P = .033), mechanical complications (OR = 8.33, 95% CI: 1.91-36.25, P = .005), neurologic complications (OR = 6.27, 95% CI: 1.40-28.10, P = .017), and renal replacement therapy (OR = 3.31, 95% CI: 1.03-10.66, P = .045). CONCLUSIONS Extracorporeal cardiopulmonary resuscitation plays a valuable role salvaging children with refractory cardiac arrest. Survival varies with underlying pathology and can be expected even with relatively longer CPR durations. Efforts to improve systemic output before and after institution of ECPR might mitigate some of the significant risk factors for mortality.

Abstract
BACKGROUND Airway management procedures are critical for emergency medicine (EM) physicians, but rarely performed skills in pediatric patients. Worldwide experience with respect to frequency and confidence in performing airway management skills has not been previously described. OBJECTIVES Our aims were 1) to determine the frequency with which emergency medicine physicians perform airway procedures including: bag-mask ventilation (BMV), endotracheal intubation (ETI), laryngeal mask airway (LMA) insertion, tracheostomy tube change (TTC), and surgical airways, and 2) to investigate predictors of procedural confidence regarding advanced airway management in children. METHODS A web-based survey of senior emergency physicians was distributed through the six research networks associated with Pediatric Emergency Research Network (PERN). Senior physician was defined as anyone working without direct supervision at any point in a 24-h cycle. Physicians were queried regarding their most recent clinical experience performing or supervising airway procedures, as well as with hands on practice time or procedural teaching. Reponses were dichotomized to within the last year, or ≥ 1 year. Confidence was assessed using a Likert scale for each procedure, with results for ETI and LMA stratified by age. Response levels were dichotomized to "not confident" or "confident." Multivariate regression models were used to assess relevant associations. RESULTS 1602 of 2446 (65%) eligible clinicians at 96 PERN sites responded. In the previous year, 1297 (85%) physicians reported having performed bag-mask ventilation, 900 (59%) had performed intubation, 248 (17%) had placed a laryngeal mask airway, 348 (23%) had changed a tracheostomy tube, and 18 (1%) had performed a surgical airway. Of respondents, 13% of physicians reported the opportunity to supervise but not provide ETI, 5% for LMA and 5% for BMV. The percentage of physicians reporting "confidence" in performing each procedure was: BMV (95%) TTC (43%), and surgical airway (16%). Clinician confidence in ETT and LMA varied by patient age. Supervision of an airway procedure was the strongest predictor of procedural confidence across airway procedures. CONCLUSION BMV and ETI were the most commonly performed pediatric airway procedures by emergency medicine physicians, and surgical airways are very infrequent. Supervising airway procedures may serve to maintain procedural confidence for physicians despite infrequent opportunities as the primary proceduralist.

Development and Usability of a Novel Interactive Tablet App (PediAppRREST) to Support the Management of Pediatric Cardiac Arrest: Pilot High-Fidelity Simulation-Based Study. JMIR Mhealth Uhealth 2020; 8:e19070. [PMID: 32788142 PMCID: PMC7563631 DOI: 10.2196/19070] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 06/26/2020] [Accepted: 07/26/2020] [Indexed: 01/22/2023] Open
Abstract
Background Pediatric cardiac arrest (PCA), although rare, is associated with high mortality. Deviations from international management guidelines are frequent and associated with poorer outcomes. Different strategies/devices have been developed to improve the management of cardiac arrest, including cognitive aids. However, there is very limited experience on the usefulness of interactive cognitive aids in the format of an app in PCA. No app has so far been tested for its usability and effectiveness in guiding the management of PCA. Objective To develop a new audiovisual interactive app for tablets, named PediAppRREST, to support the management of PCA and to test its usability in a high-fidelity simulation-based setting. Methods A research team at the University of Padova (Italy) and human–machine interface designers, as well as app developers, from an Italian company (RE:Lab S.r.l.) developed the app between March and October 2019, by applying an iterative design approach (ie, design–prototyping–evaluation iterative loops). In October–November 2019, a single-center nonrandomized controlled simulation–based pilot study was conducted including 48 pediatric residents divided into teams of 3. The same nonshockable PCA scenario was managed by 11 teams with and 5 without the app. The app user’s experience and interaction patterns were documented through video recording of scenarios, debriefing sessions, and questionnaires. App usability was evaluated with the User Experience Questionnaire (UEQ) (scores range from –3 to +3 for each scale) and open-ended questions, whereas participants’ workload was measured using the NASA Raw-Task Load Index (NASA RTLX). Results Users’ difficulties in interacting with the app during the simulations were identified using a structured framework. The app usability, in terms of mean UEQ scores, was as follows: attractiveness 1.71 (SD 1.43), perspicuity 1.75 (SD 0.88), efficiency 1.93 (SD 0.93), dependability 1.57 (SD 1.10), stimulation 1.60 (SD 1.33), and novelty 2.21 (SD 0.74). Team leaders’ perceived workload was comparable (P=.57) between the 2 groups; median NASA RTLX score was 67.5 (interquartile range [IQR] 65.0-81.7) for the control group and 66.7 (IQR 54.2-76.7) for the intervention group. A preliminary evaluation of the effectiveness of the app in reducing deviations from guidelines showed that median time to epinephrine administration was significantly longer in the group that used the app compared with the control group (254 seconds versus 165 seconds; P=.015). Conclusions The PediAppRREST app received a good usability evaluation and did not appear to increase team leaders’ workload. Based on the feedback collected from the participants and the preliminary results of the evaluation of its effects on the management of the simulated scenario, the app has been further refined. The effectiveness of the new version of the app in reducing deviations from guidelines recommendations in the management of PCA and its impact on time to critical actions will be evaluated in an upcoming multicenter simulation-based randomized controlled trial.

The current practice regarding neuro-prognostication for comatose children after cardiac arrest differs between and within European PICUs: A survey. Eur J Paediatr Neurol 2020; 28:44-51. [PMID: 32669214 DOI: 10.1016/j.ejpn.2020.06.021] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 06/19/2020] [Accepted: 06/30/2020] [Indexed: 12/14/2022]
Abstract
PURPOSE To describe current practices in European Paediatric Intensive Care Units (PICUs) regarding neuro-prognostication in comatose children after cardiac arrest (CA). METHODS An anonymous online survey was conducted among members of the European Society of Paediatric and Neonatal Intensive Care (ESPNIC) and the European Paediatric Neurology Society (EPNS) throughout January and February 2019. The survey consisted of 49 questions divided into 4 sections: general information, cardiac arrest, neuro-prognostication and follow-up. RESULTS The survey was sent to 1310 EPNS and 611 ESPNIC members. Of the 108 respondents, 71 (66%) (23 countries, 45 PICUs) completed the "neuro-prognostication" section. Eight PICUs (20%) had a local neuro-prognostication guideline. The 3 methods considered as most useful were neurological examination (92%), magnetic resonance imaging (MRI) (82%) and continuous electroencephalography (cEEG) (45%). In 50% a Pediatric Cerebral Performance Category (PCPC) score ≥ 4 was considered as poor neurological outcome. In 63% timing of determining neurological prognosis was based on the individual patient. Once decided that neurological prognosis was futile, 55% indicated that withdrawing life-sustaining therapy (WLST) was (one of) the options, whereas 44% continued PICU treatment (with or without restrictions). In 28 PICUs (68%) CA-survivors were scheduled for follow-up visits. CONCLUSION Local guidelines for neuro-prognostication in comatose children after CA are uncommon. Methods to assess neurological outcome were mainly neurological examination, MRI and cEEG. Consequences of poor outcome differed between respondents. Inaccuracies in neuro-prognostication can result in premature WLST, thereby biasing outcome research and creating a self-fulfilling cycle. Further research is needed to develop scientifically based international guidelines for neuro-prognostication in comatose children after CA.

Abstract
Background The Medical Emergency Team (MET) model was first introduced in the early 1990s and aimed to intervene at an earlier stage of patient clinical deterioration. This study aimed to describe the changes in patient demographics, patterns of activation and clinical outcomes of MET activations at our specialist paediatric hospital across a 20-year period providing the longest duration Medical Emergency Team data set published to date. Methods This single-centre observational study prospectively collected data about MET events at a single specialist paediatric hospital in Australia from 1995 to 2014. Patient demographics, activation patterns and clinical outcomes from MET activations were analysed for the 20-year period. Results 771 MET events were included in analysis. Most MET events involved children aged <5 years (median age 36 months) with decreased incidence on weekends and night shift. The most frequent reasons stated for MET activation were seizure and respiratory compromise and the most commonly recorded MET interventions were bag-valve-mask ventilation and intravascular access. There was an increase in MET event frequency (MET events per 1000 hospital separations) in the second decade of the service compared to the first (3.25 vs 1.42, p < 0.001) with fewer events for cardiopulmonary arrest but more for respiratory, cardiovascular or neurological compromise. Conclusions This study describes the longest duration MET data set published to date. The 20-year span of data demonstrates increased utilisation of the MET system and activation for patients earlier in their deterioration. The data should inform both health service planning and educational requirements for MET providers.

Abstract
AIM To report the patient characteristics and clinical outcome of paediatric in-hospital cardiac arrest in the United Kingdom (UK) National Cardiac Arrest Audit (NCAA) database. METHODS Analysis of all recorded paediatric cardiac arrests in the NCAA dataset over a seven-year period ending on 31 December 2018, within acute children's hospitals (including standalone paediatric hospitals and hospitals with tertiary paediatric services) and acute general hospitals participating in NCAA. In this period 1456 patients (with 1580 events), 1 month to 16 years of age, received chest compressions and/or defibrillation and were attended by a hospital-based resuscitation team in response to an emergency call. The main outcome measure was survival to discharge. RESULTS For this cohort of paediatric in-hospital cardiac arrest patients the overall rates of sustained return of spontaneous circulation (ROSC) were 69.1% with unadjusted survival to hospital discharge of 54.2%. The presenting rhythm was shockable in 4.3% of events and non-shockable in 82.1% (remainder undetermined); rates of survival to hospital discharge associated with these rhythms were 63.9% and 51.7%. A difference in outcomes was observed between Children's hospitals and acute general hospitals with ROSC rates of 79.1% and 55.5% respectively and survival to hospital discharge rates of 57.7% and 49.3% respectively. CONCLUSIONS These first results from the NCAA database describing the outcome of paediatric in-hospital cardiac arrest in UK hospitals will serve as a benchmark from which to assess the future impact of changes in service delivery, organisation and treatment for in-hospital cardiac arrest in young people. Outcomes for specialist paediatric centres should be studied further as higher rates of ROSC and survival to hospital discharge were observed.

Abstract
Early after pediatric cardiac arrest, families and care providers struggle with the uncertainty of long-term neurological prognosis. Cardiac arrest characteristics such as location, intra-arrest factors, and postarrest events have been associated with outcome. We paid particular attention to postarrest modalities that have been shown to predict neurological outcome. These modalities include neurological examination, somatosensory evoked potentials, electroencephalography, and neuroimaging. There is no one modality that accurately predicts neurological prognosis. Thus, a multimodal approach should be undertaken by both neurologists and intensivists to present a clear and consistent message to families. Methods used for the prediction of long-term neurological prognosis need to be specific enough to identify indivuals with a poor outcome. We review the evidence evaluating children with coma, each with various etiologies of cardiac arrest, outcome measures, and timing of follow-up.

Abstract
OBJECTIVE To analyze the main epidemiological aspects of prehospital and hospital pediatric cardiopulmonary resuscitation and the impact of scientific evidence on survival. SOURCE OF DATA This was a narrative review of the literature published at PubMed/MEDLINE until January 2019 including original and review articles, systematic reviews, meta-analyses, annals of congresses, and manual search of selected articles. SYNTHESIS OF DATA The prehospital and hospital settings have different characteristics and prognoses. Pediatric prehospital cardiopulmonary arrest has a three-fold lower survival rate than cardiopulmonary arrest in the hospital setting, occurring mostly at home and in children under 1year. Higher survival appears to be associated with age progression, shockable rhythm, emergency medical care, use of automatic external defibrillator, high-quality early life support, telephone dispatcher-assisted cardiopulmonary resuscitation, and is strongly associated with witnessed cardiopulmonary arrest. In the hospital setting, a higher incidence was observed in children under 1year of age, and mortality increased with age. Higher survival was observed with shorter cardiopulmonary resuscitation duration, occurrence on weekdays and during daytime, initial shockable rhythm, and previous monitoring. Despite the poor prognosis of pediatric cardiopulmonary resuscitation, an increase in survival has been observed in recent years, with good neurological prognosis in the hospital setting. CONCLUSIONS A great progress in the science of pediatric cardiopulmonary resuscitation has been observed, especially in developed countries. The recognition of the epidemiological aspects that influence cardiopulmonary resuscitation survival may direct efforts towards more effective actions; thus, studies in emerging and less favored countries remains a priority regarding the knowledge of local factors.

Abstract
Supplemental Digital Content is available in the text. Introduction: Pediatric in-hospital cardiac arrests and emergent transfers to the pediatric intensive care unit (ICU) represent a serious patient safety concern with associated increased morbidity and mortality. Some institutions have turned to the electronic health record and predictive analytics in search of earlier and more accurate detection of patients at risk for decompensation. Methods: Objective electronic health record data from 2011 to 2017 was utilized to develop an automated early warning system score aimed at identifying hospitalized children at risk of clinical deterioration. Five vital sign measurements and supplemental oxygen requirement data were used to build the Vitals Risk Index (VRI) model, using multivariate logistic regression. We compared the VRI to the hospital’s existing early warning system, an adaptation of Monaghan’s Pediatric Early Warning Score system (PEWS). The patient population included hospitalized children 18 years of age and younger while being cared for outside of the ICU. This dataset included 158 case hospitalizations (102 emergent transfers to the ICU and 56 “code blue” events) and 135,597 control hospitalizations. Results: When identifying deteriorating patients 2 hours before an event, there was no significant difference between Pediatric Early Warning Score and VRI’s areas under the receiver operating characteristic curve at false-positive rates ≤ 10% (pAUC10 of 0.065 and 0.064, respectively; P = 0.74), a threshold chosen to compare the 2 approaches under clinically tolerable false-positive rates. Conclusions: The VRI represents an objective, simple, and automated predictive analytics tool for identifying hospitalized pediatric patients at risk of deteriorating outside of the ICU setting.

Abstract
Background Hyperoxia during cardiopulmonary resuscitation (CPR) may lead to oxidative injury from mitochondrial‐derived reactive oxygen species, despite guidelines recommending 1.0 inspired oxygen during CPR. We hypothesized exposure to 1.0 inspired oxygen during CPR would result in cerebral hyperoxia, higher mitochondrial‐derived reactive oxygen species, increased oxidative injury, and similar survival compared with those exposed to 21% oxygen. Methods and Results Four‐week‐old piglets (n=25) underwent asphyxial cardiac arrest followed by randomization and blinding to CPR with 0.21 (n=10) or 1.0 inspired oxygen (n=10) through 10 minutes post return of spontaneous circulation. Sham was n=5. Survivors received 4 hours of protocolized postarrest care, whereupon brain was obtained for mitochondrial analysis and neuropathology. Groups were compared using Kruskal‐Wallis test, Wilcoxon rank‐sum test, and generalized estimating equations regression models. Both 1.0 and 0.21 groups were similar in systemic hemodynamics and cerebral blood flow, as well as survival (8/10). The 1.0 animals had relative cerebral hyperoxia during CPR and immediately following return of spontaneous circulation (brain tissue oxygen tension, 85% [interquartile range, 72%–120%] baseline in 0.21 animals versus 697% [interquartile range, 515%–721%] baseline in 1.0 animals; P=0.001 at 10 minutes postarrest). Cerebral mitochondrial reactive oxygen species production was higher in animals treated with 1.0 compared with 0.21 (P<0.03). Exposure to 1.0 oxygen led to increased cerebral oxidative injury to proteins and lipids, as evidenced by significantly higher protein carbonyls and 4‐hydroxynoneals compared with 0.21 (P<0.05) and sham (P<0.001). Conclusions Exposure to 1.0 inspired oxygen during CPR caused cerebral hyperoxia during resuscitation, and resultant increased mitochondrial‐derived reactive oxygen species and oxidative injury following cardiac arrest.

Abstract
Background The American Heart Association recommends use of physiologic feedback when available to optimize chest compression delivery. We compared hemodynamic parameters during cardiopulmonary resuscitation in which either end‐tidal carbon dioxide (ETCO2) or diastolic blood pressure (DBP) levels were used to guide chest compression delivery after asphyxial cardiac arrest. Methods and Results One‐ to 2‐week‐old swine underwent a 17‐minute asphyxial‐fibrillatory cardiac arrest followed by alternating 2‐minute periods of ETCO2‐guided and DBP‐guided chest compressions during 10 minutes of basic life support and 10 minutes of advanced life support. Ten animals underwent resuscitation. We found significant changes to ETCO2 and DBP levels within 30 s of switching chest compression delivery methods. The overall mean ETCO2 level was greater during ETCO2‐guided cardiopulmonary resuscitation (26.4±5.6 versus 22.5±5.2 mm Hg; P=0.003), whereas the overall mean DBP was greater during DBP‐guided cardiopulmonary resuscitation (13.9±2.3 versus 9.4±2.6 mm Hg; P=0.003). ETCO2‐guided chest compressions resulted in a faster compression rate (149±3 versus 120±5 compressions/min; P=0.0001) and a higher intracranial pressure (21.7±2.3 versus 16.0±1.1 mm Hg; P=0.002). DBP‐guided chest compressions were associated with a higher myocardial perfusion pressure (6.0±2.8 versus 2.4±3.2; P=0.02) and cerebral perfusion pressure (9.0±3.0 versus 5.5±4.3; P=0.047). Conclusions Using the ETCO2 or DBP level to optimize chest compression delivery results in physiologic changes that are method‐specific and occur within 30 s. Additional studies are needed to develop protocols for the use of these potentially conflicting physiologic targets to improve outcomes of prolonged cardiopulmonary resuscitation.

Cardiopulmonary Resuscitation in the Pediatric Cardiac Catheterization Laboratory: A Report From the American Heart Association's Get With the Guidelines-Resuscitation Registry. Pediatr Crit Care Med 2019; 20:1040-1047. [PMID: 31232852 DOI: 10.1097/pcc.0000000000002038] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
OBJECTIVES Hospitalized children with underlying heart disease are at high risk for cardiac arrest, particularly when they undergo invasive catheterization procedures for diagnostic and therapeutic interventions. Outcomes for children experiencing cardiac arrest in the cardiac catheterization laboratory remain under-reported with few studies reporting survival beyond the catheterization laboratory. We aim to describe survival outcomes after cardiac arrest in the cardiac catheterization laboratory while identifying risk factors associated with hospital mortality after these events. DESIGN Retrospective observational study of data from a multicenter cardiac arrest registry from November 2005 to November 2016. Cardiac arrest in the cardiac catheterization laboratory was defined as the need for chest compressions greater than or equal to 1 minute in the cardiac catheterization laboratory. Primary outcome was survival to discharge. Variables analyzed using generalized estimating equations for association with survival included age, illness category (surgical cardiac, medical cardiac), preexisting conditions, pharmacologic interventions, and event duration. SETTING American Heart Association's Get With the Guidelines-Resuscitation registry of in-hospital cardiac arrest. PATIENTS Consecutive patients less than 18 years old experiencing an index (i.e., first) cardiac arrest event reported to the Get With the Guidelines-Resuscitation. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 203 patients met definition of index cardiac arrest in the cardiac catheterization laboratory composed primarily of surgical and medical cardiac patients (54% and 41%, respectively). Children less than 1 year old comprised the majority of patients, 58% (117/203). Overall survival to hospital discharge was 69% (141/203). No differences in survival were observed between surgical and medical cardiac patients (p = 0.15). The majority of deaths (69%, 43/62) occurred in patients less than 1 year old. Bradycardia (with pulse) followed by pulseless electrical activity/asystole were the most common first documented rhythms observed (50% and 27%, respectively). Preexisting metabolic/electrolyte abnormalities (p = 0.02), need for vasoactive infusions (p = 0.03) prior to arrest, and use of calcium products (p = 0.005) were found to be significantly associated with lower rates of survival to discharge on multivariable regression. CONCLUSIONS The majority of children experiencing cardiac arrest in the cardiac catheterization laboratory in this large multicenter registry analysis survived to hospital discharge, with no observable difference in outcomes between surgical and medical cardiac patients. Future investigations that focus on stratifying medical complexity in addition to procedural characteristics at the time of catheterization are needed to better identify risks for mortality after cardiac arrest in the cardiac catheterization laboratory.

Abstract
AIM To examine the relationship between survival and diastolic blood pressure (DBP) throughout resuscitation from paediatric asphyxial cardiac arrest. METHODS Retrospective, secondary analysis of 200 swine resuscitations. Swine underwent asphyxial cardiac arrest and were resuscitated with predefined periods of basic and advanced life support (BLS and ALS, respectively). DBP was recorded every 30 s. Survival was defined as 20-min sustained return of spontaneous circulation (ROSC). RESULTS During BLS, DBP peaked between 1-3 min and was greater in survivors (20.0 [11.3, 33.3] mmHg) than in non-survivors (5.0 [1.0, 10.0] mmHg; p < 0.001). After this transient increase, the DBP in survivors progressively decreased but remained greater than that of non-survivors after 10 min of resuscitation (9.0 [6.0, 13.8] versus 3.0 [1.0, 6.8] mmHg; p < 0.001). During ALS, the magnitude of DBP change after the first adrenaline (epinephrine) administration was greater in survivors (22.0 [16.5, 36.5] mmHg) than in non-survivors (6.0 [2.0, 11.0] mmHg; p < 0.001). Survival rate was greater when DBP improved by ≥26 mmHg after the first dose of adrenaline (20/21; 95%) than when DBP improved by ≤10 mmHg (1/99; 1%). The magnitude of DBP change after the first adrenaline administration correlated with the timetoROSC (r = -0.54; p < 0.001). CONCLUSIONS Survival after asphyxial cardiac arrest is associated with a higher DBP throughout resuscitation, but the difference between survivors and non-survivors was reduced after prolonged BLS. During ALS, response to adrenaline administration correlates with survival and time to ROSC. If confirmed clinically, these findings may be useful for titrating adrenaline during resuscitation and prognosticating likelihood of ROSC. Institutional Protocol Numbers: SW14M223 and SW17M101.

J Paediatr Child Health 2019; 55:213-215. [PMID: 30144187 DOI: 10.1111/jpc.14185] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Revised: 07/17/2018] [Accepted: 07/24/2018] [Indexed: 11/26/2022]
Abstract
AIM To demonstrate that unrecognised situation awareness failures events (UNSAFE) transfers are associated with poorer outcomes in the intensive care unit (ICU) at a Japanese children's hospital lacking a rapid response system. METHODS This retrospective cohort study was conducted between January 2013 and February 2016. UNSAFE transfers were defined as unplanned in-hospital ward-to-ICU transfers requiring tracheal intubation, vasoactive medications or ≥3 fluid boluses before arrival or in the first 60 min of ICU care. We compared ICU stay duration and mortality between UNSAFE and non-UNSAFE transfers. RESULTS There were 2126 admissions to the paediatric ICU during the study period, and 244 cases met the definition of an unscheduled in-hospital transfer (11.5%). Of these, the number of patients transferred following cardiopulmonary resuscitation, in the UNSAFE group and in the non-UNSAFE group were 9 (3.7%), 68 (28%) and 167 (68%), respectively. In the UNSAFE group, the number of patients who required tracheal intubation, initiation of vasoactive medications or ≥ 3 fluid boluses in the first 60 min of ICU care or before arrival in the ICU was 61 (90%), 38 (56%) and 9 (13%), respectively. ICU stay duration and mortality were significantly poorer in the UNSAFE group than in the non-UNSAFE group (9 vs. 4 days, P < 0.0001; 13 vs. 4.2%, odds ratio = 3.5, 95% confidence interval = 1.2-9.8, P = 0.020, respectively). CONCLUSIONS Patients who experienced UNSAFE transfers had longer ICU stays and higher mortality, and it may be used as a metric of evaluation of effects of rapid response system implementation.

Abstract
BACKGROUND Adrenaline and vasopressin are widely used to treat people with cardiac arrest, but there is uncertainty about the safety, effectiveness and the optimal dose. OBJECTIVES To determine whether adrenaline or vasopressin, or both, administered during cardiac arrest, afford any survival benefit. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Embase and DARE from their inception to 8 May 2018, and the International Liaison Committee on Resuscitation 2015 Advanced Life Support Consensus on Science and Treatment Recommendations. We also searched four trial registers on 5 September 2018 and checked the reference lists of the included studies and review papers to identify potential papers for review. SELECTION CRITERIA Any randomised controlled trial comparing: standard-dose adrenaline versus placebo; standard-dose adrenaline versus high-dose adrenaline; and adrenaline versus vasopressin, in any setting, due to any cause of cardiac arrest, in adults and children. There were no language restrictions. DATA COLLECTION AND ANALYSIS Two review authors independently identified trials for review, assessed risks of bias and extracted data, resolving disagreements through re-examination of the trial reports and by discussion. We used risk ratios (RRs) with 95% confidence intervals (CIs) to compare dichotomous outcomes for clinical events. There were no continuous outcomes reported. We examined groups of trials for heterogeneity. We report the quality of evidence for each outcome, using the GRADE approach. MAIN RESULTS We included 26 studies (21,704 participants).Moderate-quality evidence found that adrenaline increased survival to hospital discharge compared to placebo (RR 1.44, 95% CI 1.11 to 1.86; 2 studies, 8538 participants; an increase from 23 to 32 per 1000, 95% CI 25 to 42). We are uncertain about survival to hospital discharge for high-dose compared to standard-dose adrenaline (RR 1.10, 95% CI 0.75 to 1.62; participants = 6274; studies = 10); an increase from 33 to 36 per 1000, 95% CI 24 to 53); standard-dose adrenaline versus vasopressin (RR 1.25, 95% CI 0.84 to 1.85; 6 studies; 2511 participants; an increase from 72 to 90 per 1000, 95% CI 60 to 133); and standard-dose adrenaline versus vasopressin plus adrenaline (RR 0.76, 95% CI 0.47 to 1.22; 3 studies; 3242 participants; a possible decrease from 24 to 18 per 1000, 95% CI 11 to 29), due to very low-quality evidence.Moderate-quality evidence found that adrenaline compared with placebo increased survival to hospital admission (RR 2.51, 95% CI 1.67 to 3.76; 2 studies, 8489 participants; an increase from 83 to 209 per 1000, 95% CI 139 to 313). We are uncertain about survival to hospital admission when comparing standard-dose with high-dose adrenaline, due to very low-quality evidence. Vasopressin may improve survival to hospital admission when compared with standard-dose adrenaline (RR 1.27, 95% CI 1.04 to 1.54; 3 studies, 1953 participants; low-quality evidence; an increase from 260 to 330 per 1000, 95% CI 270 to 400), and may make little or no difference when compared to standard-dose adrenaline plus vasopressin (RR 0.95, 95% CI 0.83 to 1.08; 3 studies; 3249 participants; low-quality evidence; a decrease from 218 to 207 per 1000 (95% CI 181 to 236).There was no evidence that adrenaline (any dose) or vasopressin improved neurological outcomes.The rate of return of spontaneous circulation (ROSC) was higher for standard-dose adrenaline versus placebo (RR 2.86, 95% CI 2.21 to 3.71; participants = 8663; studies = 3); moderate-quality evidence; an increase from 115 to 329 per 1000, 95% CI 254 to 427). We are uncertain about the effect on ROSC for the comparison of standard-dose versus high-dose adrenaline and standard-does adrenaline compared to vasopressin, due to very low-quality evidence. Standard-dose adrenaline may make little or no difference to ROSC when compared to standard-dose adrenaline plus vasopressin (RR 0.97, 95% CI 0.87 to 1.08; 3 studies, 3249 participants; low-quality evidence; a possible decrease from 299 to 290 per 1000, 95% CI 260 to 323).The source of funding was not stated in 11 of the 26 studies. The study drugs were provided by the manufacturer in four of the 26 studies, but neither drug represents a profitable commercial option. The other 11 studies were funded by organisations such as research foundations and government funding bodies. AUTHORS' CONCLUSIONS This review provides moderate-quality evidence that standard-dose adrenaline compared to placebo improves return of spontaneous circulation, survival to hospital admission and survival to hospital discharge, but low-quality evidence that it did not affect survival with a favourable neurological outcome. Very low -quality evidence found that high-dose adrenaline compared to standard-dose adrenaline improved return of spontaneous circulation and survival to admission. Vasopressin compared to standard dose adrenaline improved survival to admission but not return of spontaneous circulation, whilst the combination of adrenaline and vasopressin compared with adrenaline alone had no effect on these outcomes. Neither standard dose adrenaline, high-dose adrenaline,vasopressin nor a combination of adrenaline and vasopressin improved survival with a favourable neurological outcome. Many of these studies were conducted more than 20 years ago. Treatment has changed in recent years, so the findings from older studies may not reflect current practice.

Abstract
Simulation training fosters collaborative learning and improves communication among interdisciplinary teams. In this prospective observational cohort study, we evaluated the impact of interdisciplinary simulation-based team training (SBTT) on immediate learning of team performance behaviors. In a 3-month period, 30 simulation sessions were conducted and 165 staff members, including physicians, nurses, and respiratory therapists, were trained. Regression analysis showed a statistically significant improvement in team performance ( p < 0.0001). Study results demonstrate that SBTT is effective in immediate acquisition of optimal team performance behaviors by multidisciplinary pediatric intensive care unit staff, including physicians with higher level subspecialty training in the simulation environment.

Abstract
PURPOSE To assess the effects of a real-time feedback device and refresher sessions in acquiring and retaining chest compression skills. METHODS Healthcare providers participated in refresher sessions at 3-time points (blocks) over 1-year. At each block, chest compression (CC) skills were assessed on an infant and adult task trainer, in one 2-min trial without feedback (blinded), and up to three 2-min trials with feedback (unblinded). Skills retention over time was explored at three time lags: 1-3, 3-6, >6 months. Data collected included chest compression rate (100-120/min), depth (4 cm for infants and 5 cm for adults), and recoil between compressions. RESULTS Among 194 participants, achievement of excellent CC (≥90% of adequate compressions for all parameters) increased with feedback. Linear mixed models found significant (p < 0.05) improvement in rate, depth, and recoil. Performance between last unblinded trial in block 1 with the following blinded trial in block 2 significantly decayed in rate on both task trainers irrespective of time passed, while depth and recoil performance were maintained only for infants. CONCLUSIONS A real-time visual feedback device improved CC skills with better results in infants. Skills decayed over time despite two refresher sessions with feedback.

Abstract
Reducing or eliminating code blues that occur on the inpatient, noncritical care units of children's hospitals is a challenging yet achievable goal. The mechanism to accomplish this involves several levels of effort. The implementation of effective pediatric rapid response teams is a well identified part of the process. Rapid response teams can allow for appropriate clinical interventions for deteriorating patients and may ultimately result in a reduction in hospital-wide mortality as well as efficient transfer to the pediatric intensive care unit (PICU) when necessary. The timely deployment of rapid response teams is dependent upon the appropriate recognition of patients at risk for deterioration. This recognition can be optimized by relying on assessments as simple as utilization of parental intuition to those as complex as big data models which utilize multiple predictor variables extracted from the electronic medical record. Ultimately, the goal to proactively identify patients at risk of deterioration may allow for prevention of clinical decline via appropriate and timely interventions, and if unsuccessful at that level, may allow for improved outcomes via optimized resuscitation care in the PICU.

Does the Number of Fingers on the Bag Influence Volume Delivery? A Randomized Model Study of Bag-Valve-Mask Ventilation in Infants. CHILDREN-BASEL 2018; 5:children5100132. [PMID: 30248921 PMCID: PMC6209896 DOI: 10.3390/children5100132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 09/14/2018] [Accepted: 09/17/2018] [Indexed: 11/17/2022]
Abstract
We sought to compare the effectiveness of two versus five fingers used for bag-valve-mask (BVM) ventilation on effective tidal volume (VTeff) delivery in an infant resuscitation model. In a randomised cross-over study, 40 healthcare professionals ventilated a modified leak-free infant resuscitation manikin with both two and five fingers, using a self-inflating bag. The delivered and effective tidal volumes, ventilation rate, and mask leak were measured and recorded using a respiratory function monitor. We found no significant differences in the VTeff (five-finger 61.7 ± 23.9 vs. two-finger 58.8 ± 16.6 mL; p = 0.35) or ventilatory minute volume (2.71 ± 1.59 vs. 2.76 ± 1.24 L/min; p = 0.40) of both BVM ventilation techniques. However, there was an increase in the delivered tidal volume (VTdel) and mask leak when using the five-finger technique compared with the two-finger technique (VTdel 96.1 ± 19.4 vs. 87.7 ± 15.5 mL; p < 0.01; and mask leak 34.6 ± 23.0 vs. 30.0 ± 21.0%; p = 0.02). Although the five-finger technique was associated with an increased mask leak, the number of fingers used during the BVM ventilation had no effect on VTeff in an infant resuscitation model.

Factors that influence the self-reported confidence of pediatric residents as team leaders during cardiopulmonary resuscitation: A national survey. Int J Pediatr Adolesc Med 2018; 5:116-121. [PMID: 30805545 PMCID: PMC6363252 DOI: 10.1016/j.ijpam.2018.07.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 07/09/2018] [Accepted: 07/15/2018] [Indexed: 11/26/2022]
Abstract
Objective The leadership skills of pediatric residents during cardiopulmonary resuscitation (CPR) may have major impacts on their performance. These skills should be addressed during the pediatric residency training program. Therefore, we aimed to identify the perceptions of residents regarding their level of confidence in providing or leading a real pediatric CPR code, and to identify different factors that might influence their self-confidence when assuming the role of a team leader during a real CPR. Design & setting Cross-sectional paper-based and online electronic surveys were conducted in February 2017, which included all Saudi pediatric residency program trainees. Interventions A survey questionnaire was distributed to Saudi pediatric residency trainees throughout the Kingdom. The main aim was to assess their perceived level of confidence when running a real pediatric CPR code either as a team leader or as a team member. Results The survey was distributed and sent by email to 1052 residents, where it was received by 640 and 231 responded (response rate = 36%). Almost one-fifth of the respondents (19.5%) did not have a valid pediatric advanced life support (PALS) certificate. The most frequently reported obstacles to life support training were lack of time (45.8%) and its financial cost (22.7%). The mean self-reported confidence as a CPR team member was reported significantly more frequently than being a CPR team leader (mean standard deviation, SD) = 7.8 (2.1) and 6.7 (2.4) respectively, P < .001). The self-reported confidence as a CPR team leader was reported significantly more frequently in males compared with female respondents (mean ± SD = 6.7 ± 2.4 and 5.9 ± 2.4, respectively; P < .013). There was a significant positive effect of recent attendance at a real CPR event on the perceived self-rated confidence of residents as a CPR team leader (P < .001). Residents who reported that they had often assumed a real CPR leadership role had significantly greater perceived self-confidence compared with those who assumed a member role (P < .05). Furthermore, residents without a valid PALS certificate had significantly less confidence in leading CPR teams than their peers who were recently certified (P < .05). Conclusions The self-reported confidence as team leader during CPR was higher among residents who were certified in life support courses, exposed to CPR during their training, and those who assumed the role of a team leader during CPR. Our findings suggests the need to incorporate life support training courses and simulation-based mock code programs with an emphasis on the leadership in the curriculum of the pediatric residency training program.
