J Am Heart Assoc 2024; 13:e032718. [PMID: 37930073 PMCID: PMC10863821 DOI: 10.1161/jaha.123.032718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2023] [Accepted: 10/25/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Pediatric out-of-hospital cardiac arrest (POHCA) is associated with significant mortality and poor neurological outcomes. We aimed to describe the association between sociodemographic factors and POHCA risk in Ontario, Canada. METHODS AND RESULTS We conducted a province-wide case-control study at ICES, where patient records are linked across administrative databases. The case group included children (aged 1 day to 17 years) who experienced an out-of-hospital cardiac arrest between 2004 and 2020. Controls were matched up to 1:4 on age, sex, index date, and key comorbidities. We used conditional logistic regression to measure the association between sociodemographic indicators and POHCA risk. The case and control groups included 1826 and 7254 children, respectively. Children living in areas with the highest levels of material deprivation (adjusted odds ratio [aOR], 2.35 [95% CI, 1.94-2.85]) and dependency (aOR, 1.22 [95% CI, 1.01-1.48]) had a higher odds of POHCA, relative to children living in regions with the lowest levels of material deprivation and dependency, respectively. Children living in neighborhoods with the lowest levels of ethnic diversity had a higher odds of POHCA (aOR, 1.62 [95% CI, 1.30-2.01]), relative to children living in neighborhoods with the highest levels of ethnic diversity. The odds of POHCA were lower in immigrants (aOR, 0.67 [95% CI, 0.47-0.95]), relative to the general population. Northern urban residence was associated with a higher odds of POHCA (aOR, 1.45 [95% CI, 1.13-1.87]), relative to southern urban residence. CONCLUSIONS Children living in neighborhoods with high levels of marginalization may have an elevated risk of experiencing POHCA. These findings highlight the importance of addressing disparities through targeted prevention and intervention efforts.

Abstract
BACKGROUND Paediatric out-of-hospital cardiac arrest (POHCA) is associated with poor survival and severe neurological sequelae. We conducted a systematic review on the impact of sociodemographic factors across different stages of POHCA. METHODS We searched MEDLINE, EMBASE, and Web of Science from database inception to October 2022. We included studies examining the association between sociodemographic factors (i.e., race, ethnicity, migrant status and socioeconomic status [SES]) and POHCA risk, bystander cardiopulmonary resuscitation (CPR) provision, bystander automated external defibrillator (AED) application, survival (at or 30-days post-discharge), and neurological outcome. We synthesized the data qualitatively. RESULTS We screened 11,097 citations and included 18 articles (arising from 15 studies). There were 4 articles reporting on POHCA risk, 5 on bystander CPR provision, 3 on bystander AED application, 13 on survival, and 6 on neurological outcome. In all studies on POHCA risk, significant differences were found across racial groups, with minority populations being disproportionately impacted. There were no articles reporting on the association between SES and POHCA risk. Bystander CPR provision was consistently associated with race and ethnicity, with disparities impacting Black and Hispanic children. The association between bystander CPR provision and SES was variable. There was little evidence of socioeconomic or racial disparities in studies on bystander AED application, survival, and neurological outcome, particularly across adjusted analyses. CONCLUSIONS Race and ethnicity are likely associated with POHCA risk and bystander CPR provision. These findings highlight the importance of prioritizing at-risk groups in POHCA prevention and intervention efforts. Further research is needed to understand underlying mechanisms.

Abstract
The total number of annual pacemaker implantations continues to grow globally, and help patients with heart rhythm disorders with an improved quality of life and reduced mortality. The first implantable pacemakers appeared in 1965, characterized by their bulkiness, short battery life, and a single pacing mode. Innovation led to the modern pacemaker: a smaller system with improved battery life and capacity, and innovation in lead technology. Certain arrhythmia conditions may also qualify for leadless pacemaker implantation, thus eliminating the spectrum of complications that could occur with leads. Adverse events can be divided into acute (perforation, lead dislodgement, infection) and long-term (lead fractures, device infection, insulation failure). Traditional long-term complications with leads occur in 10% of patients, compared with device-related adverse effects observed in 6.7% of leadless pacemakers. Furthermore, cardiac pacemaker implantation results in quality of life improvements across all age groups. Large cardiac rehabilitation studies have demonstrated the effectiveness of exercise in reducing the physical complications involved with pacemaker implantation. Of the three randomized controlled trials examined, all of them reported some benefit of exercise in the intervention group compared with the control. The following review aims to discuss the multitude of pacemaker options potentially available for the clinician, complications, their course of management, and the path forward with innovations arising out of previous research within the field.

Abstract
Abstract
Background Intensivists indeed discharge neonatal intensive care unit (NICU) graduates after a period of physiological stability. There is, however, a real risk of life-threatening events at home. Survival after such episodes depends on time from arrest to initiation of basic life support (BLS). It is rational to train parents who would be first responders. We sought to measure objectively and prospectively, effect of BLS training on parents of NICU graduates on the psychomotor, cognitive, and affective domains of human learning.
Methods After face-to-face training sessions, proportion of home caregivers who obtained 100% marks on a pretested performance checklist for psychomotor skills of BLS on a mannequin were measured. Two other domains of learning and number of attempts required to obtain desirable results were also analyzed.
Results Median (interquartile range [IQR]) birth weight of the high-risk neonates was 1,050 g (930, 1570) and median gestational age was 29 (IQR 28, 33) weeks. More than 75% of parents had no prior exposure to BLS training. Among 46 trained caregivers, 80.4% achieved the desired score of 5 in the psychomotor performance checklist on the first attempt. A maximum of two attempts was required to reeducate and achieve score of 5 in the remaining caregivers. Forty-two (91.3%) caregivers obtained full marks on cognitive domain test. All caregivers responded positively toward affective domain questionnaire.
Conclusion It is possible to train parents in BLS measures and demonstrate their psychomotor skills on a mannequin effectively. No parents who were approached refused training or indicated anxiety in learning the skills required.

Abstract
OBJECTIVE To develop a physiological data-driven model for early identification of impending cardiac arrest in neonates and infants with cardiac disease hospitalised in the cardiovascular ICU. METHODS We performed a single-institution retrospective cohort study (11 January 2013-16 September 2015) of patients ≤1 year old with cardiac disease who were hospitalised in the cardiovascular ICU at a tertiary care children's hospital. Demographics and diagnostic codes of cardiac arrest were obtained via the electronic health record. Diagnosis of cardiac arrest was validated by expert clinician review. Minute-to-minute physiological monitoring data were recorded via bedside monitors. A generalized linear model was used to compute a minute by minute risk score. Training and test data sets both included data from patients who did and did not develop cardiac arrest. An optimal risk-score threshold was derived based on the model's discriminatory capacity for impending arrest versus non-arrest. Model performance measures included sensitivity, specificity, accuracy, likelihood ratios, and post-test probability of arrest. RESULTS The final model consisting of multiple clinical parameters was able to identify impending cardiac arrest at least 2 hours prior to the event with an overall accuracy of 75% (sensitivity = 61%, specificity = 80%) and observed an increase in probability of detection of cardiac arrest from a pre-test probability of 9.6% to a post-test probability of 21.2%. CONCLUSIONS Our findings demonstrate that a predictive model using physiologic monitoring data in neonates and infants with cardiac disease hospitalised in the paediatric cardiovascular ICU can identify impending cardiac arrest on average 17 hours prior to arrest.

Clinical Survey and Predictors of Outcomes of Pediatric Out-of-Hospital Cardiac Arrest Admitted to the Emergency Department. Sci Rep 2019; 9:7032.

Abstract
Pediatric out-of-hospital cardiac arrest (OHCA) is a rare event with severe sequelae. Although the survival to hospital-discharge (STHD) rate has improved from 2–6% to 17.6–40.2%, only 1–4% of OHCA survivors have a good neurological outcome. This study investigated the characteristics of case management before and after admittance to the emergency department (ED) associated with outcomes of pediatric OHCA in an ED. This was a retrospective study of data collected from our ED resuscitation room logbooks dating from 2005 to 2016. All records of children under 18 years old with OHCA were reviewed. Outcomes of interest included sustained return of spontaneous circulation (SROSC), STHD, and neurological outcomes. From the 12-year study period, 152 patients were included. Pediatric OHCA commonly affects males (55.3%, n = 84) and infants younger than 1 year of age (47.4%, n = 72) at home (76.3%, n = 116). Most triggers of pediatric OHCA were respiratory in nature (53.2%, n = 81). Sudden infant death syndrome (SIDS) (29.6%, n = 45), unknown medical causes (25%, n = 38), and trauma (10.5%, n = 16) were the main causes of pediatric OHCA. Sixty-two initial cardiac rhythms at the scene were obtained, most of which were asystole and pulseless electrical activity (PEA) (93.5%, n/all: 58/62). Upon ED arrival, cardiopulmonary resuscitation (CPR) was continued for 32.66 ± 20.71 min in the ED and 34.9% (n = 53) gained SROSC. Among them, 13.8% (n = 21) achieved STHD and 4.6% (n = 7) had a favorable neurological outcome. In multivariate analyses, fewer ED epinephrine doses (p < 0.05), witness of OHCA (p = 0.001), and shorter ED CPR duration (p = 0.007) were factors that increased the rate of SROSC at the ED. A longer emergency medical service (EMS) scene interval (p = 0.047) and shorter ED CPR interval (p = 0.047) improved STHD.

Abstract
Aim We recently demonstrated that asphyxiated piglets commonly had bradycardia displayed on electrocardiography (ECG) while no carotid blood flow (CBF) or audible heart sounds could be detected. Such pulseless electrical activity (PEA) in newborn infants has not previously been thoroughly described. The aim of this study was to further investigate the occurrence of non-perfusing cardiac rhythms in asphyxiated piglets and the potential implications for the success of cardiopulmonary resuscitation (CPR) and short-term survival. Methods Neonatal piglets (1–4 days, 1.7–2.4kg) had their right common carotid artery exposed and enclosed with a real-time ultrasonic flow probe. Heart rate (HR) was continuously measured and recorded using ECG. This allowed simultaneous monitoring of HR via ECG and CBF. The piglets were asphyxiated until cardiac arrest, defined as no CBF and no audible beat upon precordial auscultation. CPR was performed until return of spontaneous circulation (ROSC, defined as a HR ≥100 bpm). ECG traces were retrospectively assessed. Results Nine out of 21 piglets (43%) had QRS-complexes on their ECG while no CBF and no audible heart sounds could be detected. Five (56%) of the piglets with PEA and 12/12 (100%) piglets with asystole at cardiac arrest obtained ROSC (p = 0.02). Thirty-three per cent of the piglets with PEA versus 58% with asystole survived to 4 hours post-ROSC (p = 0.39). Conclusion Cardiac arrest in the presence of a non-perfusing cardiac rhythm on ECG is common in asphyxiated piglets. Clinical arrest in the presence of a non-perfusing cardiac rhythm on ECG may reduce the success of CPR.

Abstract
AIM To describe the epidemiology and outcomes of out-of-hospital cardiac arrest (OHCA) in a Hong Kong (HK) pediatric population and to identify factors associated with favorable outcomes. METHODS Retrospective case note review of patients younger than 18 years who presented to the emergency department of Prince of Wales Hospital, HK with cardiac arrest from 2003 to 2013. Patients were classified as infants (<1 year), children (1-11 years) and adolescents (12-18 years). Patient characteristics, OHCA details, interventions, and outcomes were reported following the Utstein format. RESULTS There were 53 patients in the study (77.4% men) and 34.6% of patients had chronic illnesses. In the infant group, 35.7% had complicated pregnancies. The incidence of OHCA in HK was 5.37 per 100,000 person-years. Out-of-hospital cardiac arrest was identified by bystanders in 62.3%, but bystander cardiopulmonary resuscitation was provided in only 28.3%. Shockable rhythms were uncommon (9.4%). Most OHCA in infants had unknown causes. In children, commonest causes were respiratory illness and environmental hazards, and in adolescents, trauma and cardiogenic events. Overall survival to hospital discharge rate was 20.8%; 13.2% had good neurological outcomes. Bystander cardiopulmonary resuscitation (odds ratio [OR], 7.44; 95% confidence interval [95% CI], 1.75-31.7; P = 0.007), prehospital return of spontaneous circulation (OR, 11.4; 95% CI, 1.75-74.7; P = 0.013), and return of spontaneous circulation within 30 minutes (OR, 90.0; 95% CI, 11.1-727; P < 0.0005) were associated with survival to discharge. CONCLUSIONS The incidence of OHCA in HK is comparable to global data. The outcome of OHCA in the pediatric population has improved over the decades. Better prehospital care could improve outcome.

Abstract
This multiorganizational literature review was undertaken to provide an evidence base for determining whether or not recommendations for out-of-hospital termination of resuscitation could be made for children who are victims of traumatic cardiopulmonary arrest. Although there is increasing acceptance of out-of-hospital termination of resuscitation for adult traumatic cardiopulmonary arrest when there is no expectation of a good outcome, children are routinely excluded from state termination-of-resuscitation protocols. The decision to withhold resuscitative efforts in a child under specific circumstances (decapitation or dependent lividity, rigor mortis, etc) is reasonable. If there is any doubt as to the circumstances or timing of the traumatic cardiopulmonary arrest, under the current status of limiting termination of resuscitation in the field to persons older than 18 years in most states, resuscitation should be initiated and continued until arrival to the appropriate facility. If the patient has arrested, resuscitation has already exceeded 30 minutes, and the nearest facility is more than 30 minutes away, involvement of parents and family of these children in the decision-making process with assistance and guidance from medical professionals should be considered as part of an emphasis on family-centered care, because the evidence suggests that either death or a poor outcome is inevitable.

Abstract
BACKGROUND In 2005 the American Heart Association released guidelines calling for routine use of automated external defibrillators during pediatric out-of-hospital arrest. The goal of this study was to determine if these guidelines are used during resuscitations. METHODS We conducted a secondary analysis of prospectively collected data from 29 U.S. cities that participate in the Cardiac Arrest Registry to Enhance Survival (CARES). Patients were included if they were older than 1 year of age and had a documented resuscitation attempt from October 1, 2005 through December 31, 2009 from an arrest presumed to be cardiac in nature. Hierarchical multivariable logistic regression analysis was used to estimate the associations between age, demographic factors, and AED use. RESULTS 129 patients were 1-8 years of age (younger children), 88 patients were 9-17 years of age (older children), and 19,338 patients were ≥18 years of age (adults). When compared to adults, younger children were less likely to be found in a shockable rhythm (young children 11.6%, adults 23.7%) and were less likely to have an AED used (young children 16.3%, adults 28.3%). Older children had a similar prevalence of shockable rhythms as adults (31.8%) and AED use (20.5%). A multivariable analysis demonstrated that, when compared to adults, younger children had decreased odds of having an AED used (OR 0.42, 95% CI 0.26-0.69), but there was no difference in AED use among older children and adults. CONCLUSIONS Young children suffering from presumed out-of-hospital cardiac arrests are less likely to have a shockable rhythm when compared to adults, and are less likely to have an AED used during resuscitation.

The two-thumb technique using an elevated surface is preferable for teaching infant cardiopulmonary resuscitation. J Pediatr 2012; 161:658-61. [PMID: 22504100 DOI: 10.1016/j.jpeds.2012.03.019] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/02/2011] [Revised: 02/01/2012] [Accepted: 03/08/2012] [Indexed: 11/21/2022]
Abstract
OBJECTIVES To determine whether the two-thumb technique is superior to the two-finger technique for administering chest compressions using the floor surface and the preferred location for performing infant cardiopulmonary resuscitation (CPR) (ie, floor, table, or radiant warmer). STUDY DESIGN Twenty Neonatal Resuscitation Program trained medical personnel performed CPR on a neonatal manikin utilizing the two-thumb vs two-finger technique, a compression to ventilation ratio of 30:2 for 2 minutes in random order on the floor, table, and radiant warmer. RESULTS Compression depth favored the two-thumb over two-finger technique on the floor (27 ± 8 mm vs 23 ± 7), table (26 ± 7 mm vs 22 ± 7), and radiant warmer (29 ± 4 mm vs 23 ± 4) (all P < .05). Per individual subject, the compression depth varied widely using both techniques and at all surfaces. More variability between compressions was observed with the two-finger vs two-thumb technique on all surfaces (P < .05). Decay in compression over time occurred and was greater with the two-finger vs two-thumb technique on the floor (-5 ± 7 vs -1 ± 6 mm; P < .05) and radiant warmer (-3 ± 6 vs -0.3 ± 2 mm; P < .05), compared with the table (-3 ± 9 vs -4 ± 5 mm). Providers favored the table over radiant warmer, with the floor least preferred and most tiring. CONCLUSIONS The two-thumb technique is superior to the two-finger technique, achieving greater depth, less variability, and less decay over time. The table was considered most comfortable and less tiring. The two-thumb technique should be the preferred method for teaching lay persons infant CPR preferably using an elevated firm surface.

Abstract
STUDY OBJECTIVES Severe events of respiratory distress can be life threatening. Although rare in some outpatient settings, effective recognition and management are essential to improving outcomes. The value of high-fidelity simulation has not been assessed for sleep technologists (STs). We hypothesized that knowledge of and comfort level in managing emergent pediatric respiratory events would improve with this innovative method. METHODS We designed a course that utilized high-fidelity human patient simulators (HPS) and that focused on rapid pediatric assessment of young children in the first 5 minutes of an emergency. We assessed knowledge of and comfort with critical emergencies that STs may encounter in a pediatric sleep center utilizing a pre/post-test study design. RESULTS Ten STs enrolled in the study, and scores from the pre- and posttest were compared utilizing a paired samples t-test. Mean participant age was 42 ± 11 years, with average of 9.3 ± 3.3 years of ST experience but minimal experience in managing an actual emergency. Average pretest score was 54% ± 17% correct and improved to 69% ± 16% after the educational intervention (p < 0.05). Participant ratings indicated the course was a well-received, innovative educational methodology. CONCLUSIONS A simulation course focusing on respiratory emergencies requiring basic life support skills during the first 5 min of distress can significantly improve the knowledge of STs. Simulation may provide a highly useful methodology for training STs in the management of rare life-threatening events.

Abstract
OBJECTIVES To describe a large cohort of children with out-of-hospital cardiac arrest with return of circulation and to identify factors in the early postarrest period associated with survival. These objectives were for planning an interventional trial of therapeutic hypothermia after pediatric cardiac arrest. METHODS A retrospective cohort study was conducted at 15 Pediatric Emergency Care Applied Research Network clinical sites over an 18-month study period. All children from 1 day (24 hrs) to 18 yrs of age with out-of-hospital cardiac arrest and a history of at least 1 min of chest compressions with return of circulation for at least 20 mins were eligible. MEASUREMENTS AND MAIN RESULTS One hundred thirty-eight cases met study entry criteria; the overall mortality was 62% (85 of 138 cases). The event characteristics associated with increased survival were as follows: weekend arrests, cardiopulmonary resuscitation not ongoing at hospital arrival, arrest rhythm not asystole, no atropine or NaHCO3, fewer epinephrine doses, shorter duration of cardiopulmonary resuscitation, and drowning or asphyxial arrest event. For the 0- to 12-hr postarrest return-of-circulation period, absence of any vasopressor or inotropic agent (dopamine, epinephrine) use, higher lowest temperature recorded, greater lowest pH, lower lactate, lower maximum glucose, and normal pupillary responses were all associated with survival. A multivariate logistic model of variables available at the time of arrest, which controlled for gender, age, race, and asystole or ventricular fibrillation/ventricular tachycardia anytime during the arrest, found the administration of atropine and epinephrine to be associated with mortality. A second model using additional information available up to 12 hrs after return of circulation found 1) preexisting lung or airway disease; 2) an etiology of arrest drowning or asphyxia; 3) higher pH, and 4) bilateral reactive pupils to be associated with lower mortality. Receiving more than three doses of epinephrine was associated with poor outcome in 96% (44 of 46) of cases. CONCLUSIONS Multiple factors were identified as associated with survival after out-of-hospital pediatric cardiac arrest with the return of circulation. Additional information available within a few hours after the return of circulation may diminish outcome associations of factors available at earlier times in regression models. These factors should be considered in the design of future interventional trials aimed to improve outcome after pediatric cardiac arrest.

Abstract
STUDY OBJECTIVES Our objective was to describe the incidence and demographics of pediatric out-of-hospital cardiac arrest (OHCA) in Korea. METHODS We identified non-traumatic OHCA patients aged less than 20 years from a Korean nationwide OHCA registry (2006-2007). Data from emergency medical service (EMS) run-sheets and hospital records were reviewed. We excluded cases with unknown hospital outcomes. Patient characteristics, treatment by EMS, and outcomes were compared by age groups: infant (<1 year), children (1-11 years), and adolescents (12-19 years). RESULTS A total of 971 patients including infants (n=299, 30.8%), children (n=305, 31.4%), and adolescents (n=367, 37.8%) met inclusion criteria. The incidence of pediatric OHCA was 4.2 per 100,000 person-years (67.1 in infants, 2.5 in children, and 3.5 in adolescents). The rate of cardiopulmonary resuscitation administered was 82.1% (infants 80.6%, children 82.0%, and adolescent 83.4%). The rate of applying automated external defibrillators and advanced airway management (endotracheal intubation or laryngeal mask airway), was only 4.1% and 2.5%, respectively. 7.4% showed ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) in the initial ECG. Survival to hospital discharge for all pediatric OHCA was 4.9% (2.9% for infants, 4.7% for children, and 7.2% of adolescents). For EMS-treated pediatric OHCA or patients with VF or pulseless VT, the rate was 5.0% and 31.6%, respectively. CONCLUSION Incidence and hospital outcomes in pediatric OHCA in Korea were comparable to other population-based nationwide reports.

Abstract
OBJECTIVES : To describe a large multicenter cohort of pediatric cardiac arrest (CA) with return of circulation (ROC) from either the in-hospital (IH) or the out-of-hospital (OH) setting and to determine whether significant differences related to pre-event, arrest event, early postarrest event characteristics, and outcomes exist that would be critical in planning a clinical trial of therapeutic hypothermia (TH). DESIGN : Retrospective cohort study. SETTING : Fifteen Pediatric Emergency Care Applied Research Network sites. PATIENTS : Patients aged 24 hours to 18 years with either IH or OH CA who had a history of at least 1 minute of chest compressions and ROC for at least 20 minutes were eligible. INTERVENTIONS : None. MEASUREMENTS AND MAIN RESULTS : A total of 491 patients met study entry criteria with 353 IH cases and 138 OH cases. Major differences between the IH and OH cohorts were observed for patient prearrest characteristics, arrest event initial rhythm described, and arrest medication use. Several postarrest interventions were used differently, however, the use of TH was similar (<5%) in both cohorts. During the 0-12-hour interval following ROC, OH cases had lower minimum temperature and pH, and higher maximum serum glucose recorded. Mortality was greater in the OH cohort (62% vs. 51%, p = 0.04) with the cause attributed to a neurologic indication much more frequent in the OH than in the IH cohort (69% vs. 20%; p < 0.01). CONCLUSIONS : For pediatric CA with ROC, several major differences exist between IH and OH cohorts. The finding that the etiology of death was attributed to neurologic indications much more frequently in OH arrests has important implications for future research. Investigators planning to evaluate the efficacy of new interventions, such as TH, should be aware that the IH and OH populations differ greatly and require independent clinical trials.

Abstract
BACKGROUND Pediatric cardiopulmonary arrests are rare. Mock codes were instituted to bridge the gap between opportunity and reality. AIM The goal was to improve medical caregivers' skills in pediatric resuscitation. METHODS All pediatric and internal medicine/pediatric (med/peds) residents were anonymously surveyed pre- and post-intervention about confidence level about codes and code skills. Twenty mock codes were conducted during the 1 year intervention period. Statistical comparisons were made between each resident pre- and post-survey, graduating third-year residents (PGY3s) prior to intervention versus PGY3s with mock codes and pediatric versus med/peds residents. RESULTS All residents significantly improved in their perception of overall skill level during the study (p < 0.0001). PGY3s were significantly more confident in their skills than PGY2s or PGY1s and PGY2s were significantly more confident than PGY1s both pre- and post-mock codes (p < 0.0001). Med/peds residents were significantly more confident in their skills than pediatric residents both pre- (p = 0.041) and post-intervention (p = 0.016). The two skills with the lowest score post-intervention were the ability to place an interosseous line and the ability to manage cardiac dysrhythmias. CONCLUSIONS Pediatric mock codes can improve resident confidence and self-assessment of their resuscitation skills. Data from surveys such as this can be used to design future skill-based educational initiatives.

Abstract
AIM The objective of this study was to describe patients who experienced an out-of-hospital cardiac arrest (OHCA) by age group. METHODS All patients who suffered from an OHCA between 1990 and 2005 and are included in the Swedish Cardiac Arrest Registry (n = 40,503) were classified into the following age groups: neonates, younger than 1 year; young children, between 1 and 4 years; older children, between 5 and 12 years; adolescents, between 13 and 17 years; young adults, between 18 and 35 years; adults not retired, between 36 and 64 years; adults retired, between 65 and 79 years; and older adults, 80 years or older. RESULTS Ventricular fibrillation was lowest in young children (3%) and highest in adults (35%). Survival to 1 month was lowest in neonates (2.6%) and highest in older children (7.8%). Children (<18 years), young adults (18-35 years), and adults (>35 years) survived to 1 month 24.5%, 21.2%, and 13.6% of cases, respectively (P = .0003 for trend) when found in a shockable rhythm. The corresponding figures for nonshockable rhythms were 3.8%, 3.2%, and 1.6%, respectively (P < .0001 for trend). CONCLUSIONS There is a large variability in characteristics and outcome among patients in various age groups who experienced an OHCA. Among the large age groups, there was a successive decline in survival with increasing age in shockable and nonshockable rhythms.

Abstract
Care of the critically ill and injured child has evolved over the last 20 years, with growth of regional pediatric critical care services, attendant subspecialties, and the proliferation of pediatric critical care training programs nationally. Concurrent with this evolution has been recognition of the need for specialty care of the critically ill child during air or ground transport to a regional pediatric center. The American Academy of Pediatrics Section on Transport Medicine has provided standards that have been adopted by many neonatal and pediatric transport teams. Team composition varies, but all share the mission of specialized transport for critically ill and injured children in a safe and expeditious process while ultimately improving patient outcome. Specialized pediatric transport teams are costly to maintain. Declining reimbursement for specialized care and reduced profit margins have resulted in extended roles for transport team members within children's hospitals. More stringent budgetary constraints have created challenges for pediatric transport teams in our constantly changing medical environment.

Abstract
OBJECTIVES Making an accurate clinical diagnosis in the field can be a great challenge with pediatric out-of-hospital cardiac arrest (OHCA). We aimed to compare the etiology of pediatric OHCA by pre-hospital clinical diagnosis with etiology by coroner's diagnosis and autopsy. DESIGN As part of the Ontario Pre-hospital Advanced Life Support (OPALS) study, we conducted a prospective cohort study including children below age 19 with OHCA during an 11-year period. Prehospital clinical diagnosis was determined by blinded review and deaths were then matched with provincial coroner's office records. The agreement between prehospital clinical diagnosis and autopsy diagnosis was derived by consensus review. Inter-observer agreement was evaluated using kappa values. RESULTS For the period 1992-2002, there were 414 cardiac arrests in children <19 years of age that matched coroner's records. Mean age was 5.9 years (S.D. 6.4 years) with 39.4% of cases under 1 year of age. Etiology by clinical diagnosis was medical 49.5%, trauma 36.0% and undetermined 14.5%. The overall kappa for clinical diagnosis compared to coroner's diagnosis was 0.62. The kappa for medical cases was 0.53, trauma was 0.93 and 'undetermined' was -0.01. Medical clinical diagnosis had a lower agreement with the coroner's diagnosis (62.4%) compared with trauma (96.0%), RR 0.65, 95% CI [0.58, 0.73]. The poorest kappas by diagnosis were for neurological (0.39), respiratory (0.42), 'other' medical (0.56), SIDS (0.58) and cardiac (0.63). The commonest coroner's diagnoses in the 'undetermined' clinical diagnosis category were: pneumonia (17.6%), seizure or post-seizure (11.8%), arrhythmia (9.8%) and aspiration (5.9%). CONCLUSION Even in an ideal situation, a clinician in the field might be unable to determine the etiology of pediatric cardiac arrest in 14.5% of cases. There is poorer agreement for 'medical' compared to 'trauma' cases. This is the largest study to date comparing clinical diagnosis of the causes of OHCA in children to the 'gold-standard' of coroner's diagnosis.

Abstract
OBJECTIVES To determine etiology of pediatric OHCA in a population-based sample from autopsy and coroner's diagnosis. DESIGN As part of the Ontario Pre-hospital Advanced Life Support (OPALS) study, we conducted a prospective cohort study including children below age 19 years with OHCA in an 11-year period. Deaths were matched with provincial coroner's office records and autopsies and investigation notes were reviewed. RESULTS From 1992 to 2002, there were 474 cardiac arrests in children below 19 years of age giving an annual incidence of 59.7 per million children. Mean age was 5.8 (S.D. 6.3), 43.0% were <1 year of age, males were 59.1%. 25.1% were bystander witnessed and 20.3% received bystander CPR. 1.9% survived to discharge. Four hundred and thirty nine matched to coroner's office records. Annual incidence rates per million by age groups were: 175.0 (age 1-4 years), 33.0 (age 5-14 years) and 61.6 (age 15-18). Annual incidence rates per million according to coroner's cause of death were: natural (26.2), accidental (17.4), suicide (3.7) and homicide (1.9). Post-mortem rate was 84.3% and Mean Injury Severity Score was 31.4 (S.D. 16.5). The commonest causes of natural death were SIDS (30.3%), cardiovascular (19.2) and respiratory (18.3%). The commonest causes of accidental death were drowning (27.5%), residential accidents (18.8%), fire (13.0%) and motor vehicle collisions (12.3%). CONCLUSION The highest mortality rates were among children age <4 years. 52.6% of deaths were from 'unnatural' causes (accidental, suicide, homicide, undetermined). Our findings will be useful for planning prevention, treatment and future research of pediatric OHCA.

Berg MD, Samson RA, Meyer RJ, Clark LL, Valenzuela TD, Berg RA. Pediatric defibrillation doses often fail to terminate prolonged out-of-hospital ventricular fibrillation in children. Resuscitation 2005; 67:63-7. [PMID: 16199288 DOI: 10.1016/j.resuscitation.2005.04.018] [Citation(s) in RCA: 35] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2005] [Revised: 04/27/2005] [Accepted: 04/27/2005] [Indexed: 10/25/2022]
Abstract
BACKGROUND The recommended dose for pediatric defibrillation is 2 J/kg, based on animal studies of brief duration ventricular fibrillation (VF) and a single pediatric study of short duration in-hospital VF. In a piglet model of out-of-hospital (prolonged) cardiac arrest, this recommended dose was usually ineffective at terminating VF. We, therefore, hypothesized that pediatric dose defibrillation may be less effective for prolonged out-of-hospital pediatric VF. METHODS We evaluated retrospectively all cardiac arrests in children less than 13 years old in Tucson from November 1998 to April 2003, with special attention to all children in ventricular fibrillation. We determined the rate of ventricular fibrillation termination after pediatric dose shocks in this cohort, and compared this rate with a published historical pediatric in-hospital defibrillation control group. A pediatric dose shock was defined as 2 J/kg (+/-10 J). All shocks in both groups were provided as monophasic damped sinusoidal waveforms. RESULTS Thirteen of 151 (9%) children with out-of-hospital cardiac arrest had documented VF. Eleven children received a total of 14 pediatric dose shocks. The median minimum untreated dispatch-to-shock time in unwitnessed arrest or collapse-to-shock in witnessed arrest for those 11 children was 11 min (interquartile range 25-75%; 9-15.5 min). Seven of the 14 pediatric dose shocks terminated the VF (six to asystole, one to pulseless electrical activity). Nine children (68%) died in the emergency department and four (31%) in the pediatric intensive care unit; none survived to hospital discharge. Failure to terminate VF after a pediatric dose shock in this study group with prolonged out-of-hospital ventricular fibrillation was substantially more common than the previously reported in-hospital data (7/14 versus 5/57; OR 10.4; 95% CI 2.6-42; P=0.001). CONCLUSIONS Termination of VF after a pediatric defibrillation dose is substantially worse for prolonged pediatric out-of-hospital VF cardiac arrest compared with in-hospital (short duration) ventricular fibrillation. The optimal pediatric defibrillation dose for prolonged VF is not known.

Abstract
STUDY OBJECTIVE We systematically summarize pediatric out-of-hospital cardiac arrest epidemiology and assess knowledge of effects of specific out-of-hospital interventions. METHODS We conducted a comprehensive review of published articles from 1966 to 2004, available through MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EmBase, and the Cochrane Registry, describing outcomes of children younger than 18 years with an out-of-hospital cardiac arrest. Patient characteristics, process of care, and outcomes were compared using pediatric Utstein outcome report guidelines. Effects of out-of-hospital care processes on survival outcomes were summarized. RESULTS Forty-one studies met inclusion criteria; 8 complied with Utstein reporting guidelines. Included in the review were 5,363 patients: 12.1% survived to hospital discharge, and 4% survived neurologically intact. Trauma patients (n=2,299) had greater overall survival (21.9%, 6.8% intact); a separate examination of studies with more rigorous cardiac arrest definition showed poorer survival (1.1% overall, 0.3% neurologically intact). Submersion injury-associated arrests (n=442) had greater overall survival (22.7%, 6% intact). Pooled data analysis of bystander cardiopulmonary resuscitation and witnessed arrest status showed increased likelihood of survival (relative risk 1.99, 95% confidence interval 1.54 to 2.57) for witnessed arrests. The effect of bystander cardiopulmonary resuscitation is difficult to determine because of study heterogeneity. CONCLUSION Outcomes from out-of-hospital pediatric cardiac arrest are generally poor. Variability may exist in survival by patient subgroups, but differences are hard to accurately characterize. Conformity with Utstein guidelines for reporting and research design is incomplete. Witnessed arrest status remains associated with improved survival. The need for prospective controlled trials remains a high priority.

Abstract
OBJECTIVE To determine if high-dose epinephrine (HDE) used during out-of-hospital cardiopulmonary arrest refractory to prehospital interventions improves return of spontaneous circulation, 24-hour survival, discharge survival, and neurological outcomes. METHODS A multicenter randomized controlled trial was conducted between May 1991 and October 1996 to compare the effectiveness of HDE versus standard-dose epinephrine (SDE) in patients having out-of-hospital cardiopulmonary arrest refractory to prehospital resuscitation efforts. Cardiopulmonary arrest was classified as "medical" or "traumatic." Two hundred thirty patients were enrolled in 7 pediatric emergency departments. Ages ranged from newborn to 22 years. Seventeen patients met exclusion criteria. Patients were assigned to receive HDE (0.1 mg/kg for the initial dose and 0.2 mg/kg for subsequent doses) or SDE (0.01 mg/kg). The main end points evaluated were return of spontaneous circulation, 24-hour survival, discharge survival, and neurological outcome. RESULTS One hundred twenty-seven patients received HDE (32 trauma patients), and 86 patients received SDE (27 trauma patients). Among medical patients, 24 (25%) of 95 experienced return of spontaneous circulation in the HDE group as compared with 9 (15%) of 59 in the SDE group (P = 0.14, chi2 = 2.17, relative risk = 1.66 [0.83-3.31]). Sixteen (17%) of 95 HDE patients and 5 (8%) of 59 SDE patients survived at least 24 hours (P = 0.14, chi2 = 2.16, relative risk = 1.99 [0.77-5.14]). Nine survivors to discharge received HDE, and 2 received SDE (P = 0.21, Fisher exact test, relative risk = 2.75 [0.61-12.28]). There were no long-term survivors among the trauma patients. Eight of 11 long-term survivors had severe neurological outcomes defined by the Glasgow Outcome Scale (2/2 SDE, 6/9 HDE; P = 0.51, Fisher exact test). CONCLUSION HDE does not improve or diminish return of spontaneous circulation, 24-hour survival, long-term survival, or neurological outcome compared with SDE in out-of-hospital cardiopulmonary arrest.

Abstract
Current literature demonstrates a paucity of information on post-resuscitation care of pediatric clients. This lack of information is somewhat understandable in light of the relatively low incidence of occurrence and the statistically poor outcome. Nurses must be aware, however, of many issues when dealing with pediatric clients and their families after an arrest episode. This article explores key concepts involved with post-resuscitation care, including the outcome of cardiopulmonary resuscitation, immediate post-resuscitation needs, emotional outcomes for the child, and family stress and grief.

Abstract
AIM To evaluate the characteristics, outcome and prognostic factors among children suffering from out of hospital cardiac arrest in Sweden. METHODS Patients aged below 18 years suffering from out of hospital cardiac arrest which were not crew witnessed and included in the Swedish cardiac arrest registry were included in the survey. This survey included the period 1990-2001 and 60 ambulance organisations covering 85% of the Swedish population (8 million inhabitants). RESULTS In all 457 children participated in the survey of which 32% were bystander witnessed and 68% received bystander CPR. Ventricular fibrillation was found in 6% of the cases. The overall survival to 1 month was 4%. The aetiology was sudden infant death syndrome in 34% and cardiac in 11%. When in a multivariate analysis considering age, sex, witnessed status, bystander CPR, initial rhythm, aetiology and the interval between call for, and arrival of, the ambulance and place of arrest only one appeared as an independent predictor of an increased chance of surviving cardiac arrest occurring outside home (adjusted odds ratio 8.7; 95% CL 2.2-58.1). CONCLUSION Among children suffering from out of hospital cardiac arrest in Sweden that were not crew witnessed, the overall survival is low (4%). The chance of survival appears to be markedly increased if the arrest occurs outside the patients home compared with at home. No other strong predictors for an increased chance of survival could be demonstrated.

Abstract
Available literature suggests a need for both initial cardiopulmonary resuscitation training and refresher courses. The establishment of a pediatric chain of survival for victims of cardiopulmonary arrest is the focus of this technical report and is advocated in the accompanying policy statement. Immediate bystander cardiopulmonary resuscitation for victims of cardiac arrest improves survival for out-of-hospital cardiac arrest. Pediatricians will improve the chance of survival of children and adults who experience cardiac arrest by advocating for basic life support training and participating in basic life support courses as participants and teachers.

Abstract
Although children do not suffer from ventricular fibrillation (VF) as frequently as adults, it does occur in 10% to 20% of pediatric cardiac arrests. The technology is available to recognize and treat ventricular fibrillation in children as quickly as we can for adults. This article discusses the evidence to support automated external defibrillator use in young children. As this technology gains increased acceptance, resuscitation rates and outcomes for VF in children should approach those that are seen in adults.

Abstract
AIM To describe the epidemiology of children and young adults suffering from out-of-hospital cardiac arrest. PATIENTS All patients suffering from out-of-hospital cardiac arrest in whom, resuscitation efforts were attempted in the community of Göteborg between 1980 and 2000. METHODS Between 31 October 1980 and 31 October 2000, all consecutive cases of cardiac arrest in which the emergency medical service (EMS) system responded and attempted resuscitation were reported and followed-up to discharge from hospital. RESULTS Among 5505 cardiac arrests information on age was available in 5290 cases (96%). Of these 5290 cases 98 (2%) were children (age 0-17 years), 197 (4%) were young adults (age 18-35 years) and the remaining 4995 (94%) were adults (age >35 years). Children and young adults differed from adults by suffering from a witnessed arrest less frequently, being found by the ambulance crew in ventricular fibrillation/tachycardia less frequently and being judged as having an underlying cardiac aetiology less frequently. Of the children only 5% were discharged from hospital alive compared with 8% for young adults and 9% for adults. Among survivors the cerebral performance categories (CPC) score at discharge tended to differ with 38% of young adults registering a CPC score of 1 (no neurological deficit) compared with 52% among adults. CONCLUSION Children and young adults suffering from out-of-hospital cardiac arrest differed from adults in terms of aetiology and observed initial arrhythmia. Children had a particularly bad outcome whereas young adults had a similar outcome as adults.

Abstract
OBJECTIVE For adults, 150-J fixed-energy, impedance-compensating biphasic truncated exponential (ICBTE) shocks are now effectively used in automated defibrillators. However, the high energy levels delivered by adult automated defibrillators preclude their use for pediatric patients. Accordingly, we investigated a method by which adult automated defibrillators may be adapted to deliver a 50-J ICBTE shock for pediatric defibrillation. DESIGN Prospective, randomized study. SETTING A university-affiliated research institution. SUBJECT Domestic piglets. INTERVENTIONS We initially investigated four groups of anesthetized mechanically ventilated piglets weighing 3.8, 7.5, 15, and 25 kg. Ventricular fibrillation was induced with an AC current delivered to the right ventricular endocardium. After 7 mins of untreated ventricular fibrillation, a conventional manual defibrillator was used to deliver up to three 50-J ICBTE shocks. If ventricular fibrillation was not reversed, a 1-min interval of precordial compression preceded a second sequence of up to three shocks. The protocol was repeated until spontaneous circulation was restored, or for a total of 15 mins. In a second set of experiments, we evaluated a 150-J biphasic adult automated defibrillator that was operated in conjunction with energy-reducing electrodes such as to deliver 50-J shocks. The same resuscitation protocol was then exercised on piglets weighing 3.7, 13.5, and 24.2 kg. MEASUREMENTS AND MAIN RESULTS All animals were successfully resuscitated. Postresuscitation hemodynamic and myocardial function quickly returned to baseline values in both experimental groups, and all animals survived. CONCLUSION An adaptation of a 150-J biphasic adult automated defibrillator in which energy-reducing electrodes delivered 50-J shocks successfully resuscitated animals ranging from 3.7 to 25 kg without compromise of postresuscitation myocardial function or survival.

Abstract
OBJECTIVE We recently demonstrated that vasopressin alone resulted in a poorer outcome in a pediatric porcine model of asphyxial cardiac arrest when compared with epinephrine alone or with epinephrine plus vasopressin in combination. Accordingly, this study was designed to differentiate whether the inferior effects of vasopressin in pediatrics were caused by the type of cardiac arrest. DESIGN Prospective, randomized laboratory investigation that used an established porcine model for measurement of hemodynamic variables and organ blood flow. SETTING University hospital laboratory. SUBJECTS Eighteen piglets weighing 8-11 kg. INTERVENTIONS After 8 mins of ventricular fibrillation and 8 mins of cardiopulmonary resuscitation, either 0.4 units/kg vasopressin (n = 6), 45 microg/kg epinephrine (n = 6), or a combination of 45 microg/kg epinephrine with 0.8 units/kg vasopressin (n = 6) was administered. Six minutes after drug administration, a second respective bolus dose of 0.8 units/kg vasopressin, 200 microg/kg epinephrine, or a combination of 200 microg/kg epinephrine with 0.8 units/kg vasopressin was given. Defibrillation was attempted 20 mins after initiating cardiopulmonary resuscitation. MEASUREMENTS AND MAIN RESULTS Mean +/- sem left ventricular myocardial blood flow 2 mins after each respective drug administration was 65 +/- 4 and 70 +/- 13 mL x min(-1) x 100 g(-1) in the vasopressin group; 83 +/- 42 and 85 +/- 41 mL x min(-1) x 100 g(-1) in the epinephrine group; and 176 +/- 32 and 187 +/- 29 mL x min(-1) x 100 g(-1) in the epinephrine-vasopressin group (p <.006 after both doses of epinephrine-vasopressin vs. vasopressin and after the first dose of epinephrine-vasopressin vs. epinephrine, respectively). At the same times, mean +/- sem total cerebral blood flow was 73 +/- 3 and 47 +/- 5 mL x min(-1) x 100 g(-1) after vasopressin; 18 +/- 2 and 12 +/- 2 mL x min(-1) x 100 g(-1) after epinephrine; and 79 +/- 21 and 41 +/- 8 mL x min(-1) x 100 g(-1) after epinephrine-vasopressin (p <.025 after both doses of vasopressin and epinephrine-vasopressin vs. epinephrine). Five of six vasopressin-treated, two of six epinephrine-treated, and six of six epinephrine-vasopressin treated animals had return of spontaneous circulation (nonsignificant). CONCLUSIONS In this pediatric porcine model of ventricular fibrillation, the combination of epinephrine with vasopressin during cardiopulmonary resuscitation resulted in significantly higher levels of left ventricular myocardial blood flow than either vasopressin alone or epinephrine alone. Both vasopressin alone and the combination of epinephrine with vasopressin, but not epinephrine alone, improved total cerebral blood flow during cardiopulmonary resuscitation. In stark contrast to asphyxial cardiac arrest, vasopressin alone or in combination with epinephrine appears to be of benefit after ventricular fibrillation in the pediatric porcine model.

Abstract
STUDY OBJECTIVE Controversy surrounds the use of buffers during cardiac arrest to correct acidosis. The objective of this study was to determine whether attenuation or neutralization of cerebral acidosis by Carbicarb alters hippocampal glutamate levels, neuronal cell death, and neurologic deficits after reperfusion from asphyxial cardiac arrest in rats. METHODS Rats were prospectively randomized to either a control (n=45), low-dose Carbicarb (LDC; 3 mL/kg, n=45), or high-dose Carbicarb (HDC; 6 mL/kg, n=45) group in a blinded fashion during resuscitation after 8 minutes of asphyxial cardiac arrest. Microdialysis was used to assess brain pH and glutamate. A neurologic deficit score and neuronal cell death in the hippocampus were determined at day 7. RESULTS Resuscitation was greatest in LDC rats (42/45) and least in HDC rats (28/45) versus that in control rats (34/45). Brain pH was higher in the LDC and HDC rats 10 minutes after resuscitation and remained higher than that of control rats for 120 minutes after resuscitation. Glutamate levels at 10 to 120 minutes after reperfusion were lowest in the LDC rats. LDC rats had the lowest neurologic deficit score (1+/-2) versus that of control rats (13+/-8) and HDC rats (19+/-6). Hippocampal neuronal cell death was lowest in LDC rats (30+/-20) versus that in control rats (86+/-47) and HDC rats (233+/-85). CONCLUSION LDC administered during resuscitation from asphyxial cardiac arrest attenuated acidosis, improved resuscitation, and reduced neurologic deficits and the number of dead hippocampal neurons. Neutralization of cerebral acidosis with HDC increased the number of dead hippocampal neurons and neurologic deficits after resuscitation from cardiac arrest in rats.

Abstract
PURPOSE Injury is the leading cause of cardiac arrest in children older than 1 year. Previous findings suggest that children who require cardiopulmonary resuscitation (CPR) administered by paramedics for any reason rarely survive to hospital discharge. The authors evaluated the outcome of children sustaining cardiac arrest after blunt trauma in a Regional Pediatric Trauma Center. METHODS Children (age < 16) who underwent CPR in the field or in the emergency department (ED) after blunt trauma were identified from the trauma registry of a regional pediatric trauma center over a 3-year period (1997 to 2000). Patient demographics, rate of survival to discharge, factors influencing survival, and organ donation data were obtained from the trauma registry and medical record. Probability of survival (Ps) was calculated by TRISS analysis. RESULTS Twenty-five children were identified with a history of cardiac arrest after blunt injury (mean age; 3.3 years; range, 0.1 to 10; mean ISS, 30.7; range, 13-75; mean RTS, 1.58). Mean calculated Ps was 22.7%. However, only 2 (8%) survived. Death in the majority (91%) of the 23 patients who died occurred secondary to brain or spinal cord injury, and only 2 (9%) occurred as the result of exsanguinating hemorrhage. CPR was first performed in the field in 10 patients (40%), en route in 6 (24%), and in the ED in 9 (36%). Of the children who survived, both had vitals in the field, and CPR was administered initially in the ED. Mean length of ED resuscitation before death was 80 minutes. Of the children who died, organ donation occurred in only 3 (13%). The 2 survivors had no head injury and were discharged within 3 weeks of injury. CONCLUSIONS Cardiopulmonary resuscitation after blunt injury in children rarely results in survival. The majority of deaths occur as a result of isolated intracranial injury and not exsanguinating hemorrhage. Although all children should receive aggressive resuscitation after injury, the need for CPR in the field portends a poor outcome. Furthermore, these data would suggest that prolonged or heroic efforts for children sustaining cardiac arrest in the field are not indicated.
