RESUMO
OBJECTIVES: To present recommendations and consensus statements with supporting literature for the clinical management of neonates and children supported with extracorporeal membrane oxygenation (ECMO) from the Pediatric ECMO Anticoagulation CollaborativE (PEACE) consensus conference. DATA SOURCES: Systematic review was performed using PubMed, Embase, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021, followed by serial meetings of international, interprofessional experts in the management ECMO for critically ill children. STUDY SELECTION: The management of ECMO anticoagulation for critically ill children. DATA EXTRACTION: Within each of eight subgroup, two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts. DATA SYNTHESIS: A systematic review was conducted using MEDLINE, Embase, and Cochrane Library databases, from January 1988 to May 2021. Each panel developed evidence-based and, when evidence was insufficient, expert-based statements for the clinical management of anticoagulation for children supported with ECMO. These statements were reviewed and ratified by 48 PEACE experts. Consensus was obtained using the Research and Development/UCLA Appropriateness Method. Results were summarized using the Grading of Recommendations Assessment, Development, and Evaluation method. We developed 23 recommendations, 52 expert consensus statements, and 16 good practice statements covering the management of ECMO anticoagulation in three broad categories: general care and monitoring; perioperative care; and nonprocedural bleeding or thrombosis. Gaps in knowledge and research priorities were identified, along with three research focused good practice statements. CONCLUSIONS: The 91 statements focused on clinical care will form the basis for standardization and future clinical trials.

OBJECTIVES: To derive systematic-review informed, modified Delphi consensus regarding the medications used for anticoagulation for pediatric extracorporeal membrane oxygenation (ECMO) for the Pediatric ECMO Anticoagulation CollaborativE (PEACE). DATA SOURCES: A structured literature search was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021. STUDY SELECTION: Included studies assessed anticoagulation used in pediatric ECMO. DATA EXTRACTION: Two authors reviewed all citations independently, with a third reviewer adjudicating any conflicts. Eighteen references were used for data extraction as well as for creation of recommendations. Evidence tables were constructed using a standardized data extraction form. DATA SYNTHESIS: Risk of bias was assessed using the Quality in Prognosis Studies tool. The evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. Forty-eight experts met over 2 years to develop evidence-informed recommendations and, when evidence was lacking, expert-based consensus statements, or good practice statements for anticoagulation during pediatric ECMO. A web-based modified Delphi process was used to build consensus via the Research and Development/University of California Appropriateness Method. Consensus was based on a modified Delphi process with agreement defined as greater than 80%. Two recommendations, two consensus statements, and one good practice statement were developed, and, in all, agreement greater than 80% was reached. CONCLUSIONS: There is insufficient evidence to formulate optimal anticoagulation therapy during pediatric ECMO. Additional high-quality research is needed to inform evidence-based practice for anticoagulation during pediatric ECMO.

OBJECTIVES: To identify and prioritize research questions for anticoagulation and hemostasis management of neonates and children supported with extracorporeal membrane oxygenation (ECMO) from the Pediatric ECMO Anticoagulation CollaborativE (PEACE) consensus. DATA SOURCES: Systematic review was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2021, followed by serial consensus conferences of international, interprofessional experts in the management of ECMO for critically ill neonates and children. STUDY SELECTION: The management of ECMO anticoagulation for critically ill neonates and children. DATA EXTRACTION: Within each of the eight subgroups, two authors reviewed all citations independently, with a third independent reviewer resolving any conflicts. DATA SYNTHESIS: Following the systematic review of MEDLINE, EMBASE, and Cochrane Library databases from January 1988 to May 2021, and the consensus process for clinical recommendations and consensus statements, PEACE panel experts constructed research priorities using the Child Health and Nutrition Research Initiative methodology. Twenty research topics were prioritized, falling within five domains (definitions and outcomes, therapeutics, anticoagulant monitoring, protocolized management, and impact of the ECMO circuit and its components on hemostasis). CONCLUSIONS: We present the research priorities identified by the PEACE expert panel after a systematic review of existing evidence informing clinical care of neonates and children managed with ECMO. More research is required within the five identified domains to ultimately inform and improve the care of this vulnerable population.

Data comparing surgical systemic-to-pulmonary artery shunt and patent ductus arteriosus (PDA) stent as the initial palliation procedure for patients with pulmonary atresia with intact ventricular septum (PA-IVS) are limited. We sought to compare characteristics and outcomes in a multicenter cohort of patients with PA-IVS undergoing surgical shunts versus PDA stents. We retrospectively reviewed neonates with PA-IVS from 2009 to 2019 in 19 United States centers. Bivariate comparisons and multivariable logistic regression analysis were performed to determine the relationship between initial palliation strategy and outcomes including major adverse cardiovascular events (MACE): stroke, mechanical circulatory support, cardiac arrest, or death. 187 patients were included: 38 PDA stents and 149 surgical shunts. Baseline characteristics did not differ statistically between groups. Post-procedural MACE occurred in 4 patients (11%) with PDA stents versus 38 (26%) with surgical shunts, p = 0.079. Overall, the initial palliation strategy was not significantly associated with MACE (aOR:0.37; 95% CI,0.13-1.02). In patients with moderate-to-severe right ventricle hypoplasia, PDA stents were significantly associated with decreased odds of MACE (aOR:0.36; 95% CI,0.13-0.99). PDA stents were associated with lower vasoactive inotrope scores (median 0 versus 5, p < 0.001), greater likelihood to be extubated at the end of their procedure (37% versus 4%, p < 0.001), and shorter duration of mechanical ventilation (median 24 versus 96 h, p < 0.001). PDA stents were associated with significantly more unplanned reinterventions for hypoxemia compared to surgical shunts (42% vs. 20%, p = 0.009). In this multicenter study, neonates with PA-IVS who underwent PDA stenting received less vasoactive and ventilatory support postoperatively compared to those who had surgical shunts. Furthermore, patients with the most severe morphology had decreased odds of MACE.
RESUMO
We sought to report characteristics and outcomes of children with complex anomalous left coronary artery from the pulmonary artery (ALCAPA) and to compare the outcomes to children with isolated ALCAPA. We performed a retrospective data analysis of children with ALCAPA who underwent cardiac surgery between 1/2009 and 3/2018 at 21 centers. Characteristics and outcomes of patients with complex ALCAPA are provided using descriptive statistics. Outcomes were compared between complex ALCAPA and isolated ALCAPA using Fisher's exact test. We reviewed 258 patients who underwent surgical repair of ALCAPA at 21 centers. We identified 10 patients (3.9%) with complex ALCAPA. Median age at initial cardiac surgery was 49 days (range: 4 days, 12.8 years). Cardiac lesions associated with ALCAPA were HLHS (n = 3); scimitar syndrome (n = 2); VSD with aortic coarctation (n = 2); VSD with right pulmonary artery discontinuity (1); DORV with mitral atresia (n = 1); and ToF (n = 1). ALCAPA was diagnosed prior to surgical intervention in 1 patient; during the initial cardiac surgery in 4 patients; in the early postoperative period via cardiac catheterization in 3 patients; and later in childhood after initial surgical repair in 2 patients. Following ALCAPA repair, patients with complex ALCAPA, as compared to patients with isolated ALCAPA, were more likely to be placed on ECMO (50% vs 12%, p = 0.002), receive CPR (30% vs 6%, p = 0.017), or suffer operative mortality (50% vs 3%, p < 0.001). Complex ALCAPA is uncommon. All but one with complex ALCAPA was not diagnosed preoperatively and postoperative morbidity and mortality were significantly greater in these complex patients compared to patients with isolated ALCAPA.
RESUMO
Pediatric pulmonary embolism occurs in 8.6-57 per 100,000 hospitalised children. We report a novel case of bilateral pulmonary emboli in a child presenting with dyspnoea who was found to have large right ventricular myxoma and subsequent diagnosis of Carney complex. After resection of the right ventricular myxoma and bilateral pulmonary embolectomy, she had a full recovery and an excellent outcome.
RESUMO
OBJECTIVE: Emergent resuscitation of postoperative paediatric cardiac surgical patients requires specialised skills and multidisciplinary teamwork. Bedside resternotomy is a rare but life-saving procedure and few studies focus on ways to prepare providers and improve performance. We created a multidisciplinary educational intervention that addressed teamwork and technical skills. We aimed to evaluate the efficiency of the intervention to decrease time to perform critical tasks and improve caregiver comfort. METHODS: A simulation-based, in situ resternotomy educational intervention was implemented. Pre-intervention data were collected. Educational aids were used weekly during day and night nursing huddles over a three-month period. All ICU charge nurses had separate educational sessions with study personnel and were required to demonstrate competency in all the critical tasks. Post-intervention simulations were performed after intervention and at 6 months and post-intervention surveys were performed. RESULTS: A total of 186 providers participated in the intervention. There was a decrease in time to obtain defibrillator, setup resternotomy equipment and internal defibrillator paddles and deliver sedation and fluid (all p < 0.05). Time to escort family from the room and obtain blood was significantly decreased after intervention (p < 0.05). There was no difference in time to first dose of epinephrine, defibrillator pads on the patient, or time to call the cardiovascular surgeon or blood bank. Providers reported increased comfort in identifying equipment needed for resternotomy (p < 0.01) and setting up the internal defibrillator paddles (p < 0.01). CONCLUSIONS: Implementation of a novel educational intervention increased provider comfort and decreased time to perform critical tasks in an emergent resternotomy scenario.
RESUMO
AIM: To evaluate associations between characteristics of simulated point-of-care cardiopulmonary resuscitation (CPR) training with simulated and actual intensive care unit (ICU) CPR performance, and with outcomes of children after in-hospital cardiac arrest. METHODS: This is a pre-specified secondary analysis of the ICU-RESUScitation Project; a prospective, multicentre cluster randomized interventional trial conducted in 18 ICUs from October 2016-March 2021. Point-of-care bedside simulations with real-time feedback to allow multidisciplinary ICU staff to practice CPR on a portable manikin were performed and quality metrics (rate, depth, release velocity, chest compression fraction) were recorded. Actual CPR performance was recorded for children 37 weeks post-conceptual age to 18 years who received chest compressions of any duration, and included intra-arrest haemodynamics and CPR mechanics. Outcomes included survival to hospital discharge with favourable neurologic status. RESULTS: Overall, 18,912 point-of-care simulations were included. Simulation characteristics associated with both simulation and actual performance included site, participant discipline, and timing of simulation training. Simulation characteristics were not associated with survival with favourable neurologic outcome. However, participants in the top 3 sites for improvement in survival with favourable neurologic outcome were more likely to have participated in a simulation in the past month, on a weekday day, to be nurses, and to achieve targeted depth of compression and chest compression fraction goals during simulations than the bottom 3 sites. CONCLUSIONS: Point-of-care simulation characteristics were associated with both simulated and actual CPR performance. More recent simulation, increased nursing participation, and simulation training during daytime hours may improve CPR performance.

AIM: To evaluate associations between calcium administration and outcomes among children with in-hospital cardiac arrest and among specific subgroups in which calcium use is hypothesized to provide clinical benefit. METHODS: This is a secondary analysis of observational data collected prospectively as part of the ICU-RESUScitation project. Children 37 weeks post-conceptual age to 18 years who received chest compressions in one of 18 intensive care units from October 2016-March 2021 were eligible. Data included child and event characteristics, pre-arrest laboratory values, pre- and intra-arrest haemodynamics, and outcomes. Outcomes included sustained return of spontaneous circulation (ROSC), survival to hospital discharge, and survival to hospital discharge with favourable neurologic outcome. A propensity score weighted cohort was used to evaluate associations between calcium use and outcomes. Subgroups included neonates, and children with hyperkalaemia, sepsis, renal insufficiency, cardiac surgery with cardiopulmonary bypass, and calcium-avid cardiac diagnoses. RESULTS: Of 1,100 in-hospital cardiac arrests, median age was 0.63 years (IQR 0.19, 3.81); 450 (41%) received calcium. Among the weighted cohort, calcium use was not associated with sustained ROSC (aOR, 0.87; CI95 0.61-1.24; p = 0.445), but was associated with lower rates of both survival to hospital discharge (aOR, 0.68; CI95 0.52-0.89; p = 0.005) and survival with favourable neurologic outcome at hospital discharge (aOR, 0.75; CI95 0.57-0.98; p = 0.038). Among subgroups, calcium use was associated with lower rates of survival to hospital discharge in children with sepsis and renal insufficiency. CONCLUSIONS: Calcium use was common during paediatric in-hospital cardiac arrest and associated with worse outcomes at hospital discharge.

BACKGROUND: Multicenter contemporary data describing short-term outcomes after initial interventions of neonates with pulmonary atresia with intact ventricular septum (PA-IVS) are limited. This multicenter study describes characteristics and outcomes of PA-IVS neonates after their initial catheter or surgical intervention and identifies factors associated with major adverse cardiac events (MACE). METHODS: Neonates with PA-IVS who underwent surgical or catheter intervention between 2009 and 2019 in 19 centers were reviewed. Risk factors for MACE, defined as cardiopulmonary resuscitation, mechanical circulatory support, stroke, or in-hospital mortality, were analyzed using multivariable logistic regression models. RESULTS: We reviewed 279 neonates: 79 (28%) underwent right ventricular decompression, 151 (54%) underwent systemic-to-pulmonary shunt or ductal stent placement only, 36 (13%) underwent right ventricular decompression with shunt or ductal stent placement, and 11 (4%) underwent transplantation. MACE occurred in 57 patients (20%): 26 (9%) received mechanical circulatory support, 37 (13%) received cardiopulmonary resuscitation, stroke occurred in 16 (6%), and 23 (8%) died. The presence of 2 major coronary artery stenoses (adjusted odds ratio, 4.99; 95% CI, 1.16-21.39) and lower weight at first intervention (adjusted odds ratio, 1.52; 95% CI, 1.01-2.27) were significantly associated with MACE. Coronary ischemia was the most frequent presumed mechanism of death (n = 10). CONCLUSIONS: In a multicenter cohort, 1 in 5 neonates with PA-IVS experienced MACE after their initial intervention. Patients with 2 major coronary artery stenoses or lower weight at the time of the initial procedure were most likely to experience MACE and warrant vigilance during preintervention planning and postintervention management.

BACKGROUND: Truncus arteriosus with interrupted aortic arch (TA-IAA) is a rare congenital heart defect with historically poor outcomes. Contemporary multicenter data are limited. METHODS: A retrospective cohort study of children who underwent repair of TA-IAA between 2009 and 2016 at 12 tertiary care referral centers within the United States was performed. Major adverse cardiac events (MACE) were defined as postoperative extracorporeal membrane oxygenation, cardiopulmonary resuscitation, or operative mortality. TA-IAA patients were compared with TA patients who underwent repair during the study period from the same institutions. RESULTS: We reviewed 35 patients with TA-IAA. MACE occurred in 12 patients (34%). Improvement over time was observed during the study period with 11 events (92%) occurring in the first half of the study period (P = .03). Factors associated with MACE included moderate or severe truncal valve insufficiency (P < .01), concomitant truncal valve repair (P = .04), and longer cardiopulmonary bypass duration (P = .02). In comparison with 216 patients who underwent TA repair, patients with TA-IAA had a higher rate of MACE, but this finding was not statistically significant (34% vs 20%, respectively; P = .07). Additionally no differences between TA-IAA and TA groups were observed for unplanned reoperations (14% vs 22%, respectively; P = .3), hospital length of stay (24 vs 23 days, P = .65), or late deaths (7% vs 7%, P = 1.00). CONCLUSIONS: In this contemporary, multicenter cohort the rate of MACE after repair of TA-IAA was high but improved during the study period. Early childhood outcomes of patients with TA-IAA were similar to those with TA.

OBJECTIVES: To describe nonhospitalized adult rapid response events (adult RREs) in a freestanding children's hospital and examine the relationship between various demographic and clinical factors with the final patient disposition. METHODS: We retrospectively reviewed records for nonhospitalized patients ≥18 years of age from events that occurred in a freestanding pediatric hospital between January 2011 through December 2020. We examined the relationship between adult RREs and patient demographic information, medical history, interventions, and patient disposition following an adult RRE. RESULTS: Four hundred twenty-nine events met inclusion criteria for analysis. Most events (69%) occurred in females, 49% of events occurred in family members of patients, and 47% occurred on inpatient floor and ICU areas. The most common presenting complaint was syncope or dizziness (36%). Delivery of bad news or grief response was associated with 14% of adult RREs. Overall, 46% (n = 196) of patients were transferred to the pediatric emergency department (ED). Patients requiring acute intervention or with cardiac or neurologic past medical histories were more likely to be transferred to the pediatric ED. Acute advanced cardiac life support interventions were infrequent but, of the patients taken to the pediatric ED, 1 died, and 3 were admitted to the ICU. CONCLUSIONS: Adult RREs are common in freestanding children's hospitals and, although rare, some patients required critical care. Expertise in adult critical care management should be available to the rapid response team and additional training for the pediatric rapid response team in caring for adult nonpatients may be warranted.

OBJECTIVES: To evaluate associations between sodium bicarbonate use and outcomes during pediatric in-hospital cardiac arrest (p-IHCA). DESIGN: Prespecified secondary analysis of a prospective, multicenter cluster randomized interventional trial. SETTING: Eighteen participating ICUs of the ICU-RESUScitation Project (NCT02837497). PATIENTS: Children less than or equal to 18 years old and greater than or equal to 37 weeks post conceptual age who received chest compressions of any duration from October 2016 to March 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Child and event characteristics, prearrest laboratory values (2-6 hr prior to p-IHCA), pre- and intraarrest hemodynamics, and outcomes were collected. In a propensity score weighted cohort, the relationships between sodium bicarbonate use and outcomes were assessed. The primary outcome was survival to hospital discharge. Secondary outcomes included return of spontaneous circulation (ROSC) and survival to hospital discharge with favorable neurologic outcome. Of 1,100 index cardiopulmonary resuscitation events, median age was 0.63 years (interquartile range, 0.19-3.81 yr); 528 (48.0%) received sodium bicarbonate; 773 (70.3%) achieved ROSC; 642 (58.4%) survived to hospital discharge; and 596 (54.2%) survived to hospital discharge with favorable neurologic outcome. Among the weighted cohort, sodium bicarbonate use was associated with lower survival to hospital discharge rate (adjusted odds ratio [aOR], 0.7; 95% CI, 0.54-0.92; p = 0.01) and lower survival to hospital discharge with favorable neurologic outcome rate (aOR, 0.69; 95% CI, 0.53-0.91; p = 0.007). Sodium bicarbonate use was not associated with ROSC (aOR, 0.91; 95% CI, 0.62-1.34; p = 0.621). CONCLUSIONS: In this propensity weighted multicenter cohort study of p-IHCA, sodium bicarbonate use was common and associated with lower rates of survival to hospital discharge.

Pediatric cardiac critical care has evolved with advances in congenital heart surgery, interventional cardiac catheterization, and diagnostic advances. Debate remains over the optimal location of care and training background despite data showing that systems established in collaboration with multidisciplinary experts in the care of children with congenital heart disease are associated with the best outcomes. Operative mortality is low, and preventing morbidity is the new focus of the future. Advances in screening and fetal diagnosis, mechanical circulatory support, and collaborative research and quality improvement initiatives are reviewed in this article.

Neonatal and pediatric extracorporeal membrane oxygenation (ECMO) has evolved over the past 50 years. Advances in technology, expertise, and application have increased the number of centers providing ECMO with expanded indications for use. However, increasing the use of ECMO in recent years to more medically complex critically ill children has not changed overall survival despite increased experience and improvements in technology. This review focuses on ECMO history, circuits, indications and contraindications, management, complications, and outcome data. The authors highlight important areas of progress, including unintubated and awake patients on ECMO, application during the COVID-19 pandemic, and future directions.

Contemporary multicenter data regarding midterm outcomes for neonates with pulmonary atresia with intact ventricular septum are lacking. We sought to describe outcomes in a contemporary multicenter cohort, determine factors associated with end-states, and evaluate the effect of right ventricular coronary dependency and coronary atresia on transplant-free survival. Neonates treated during 2009-2019 in 19 United States centers were reviewed. Competing risks analysis was performed to determine cumulative risk of each end-state, and multivariable regression analyses were performed to identify factors associated with each end-state and transplant-free survival. We reviewed 295 patients. Median tricuspid valve Z-score was - 3.06 (25%, 75%: - 4.00, - 1.52). Final end-state was biventricular repair for 45 patients (15.2%), one-and-a half ventricle for 16 (5.4%), Fontan for 75 (25.4%), cardiac transplantation for 29 (9.8%), and death for 54 (18.3%). Seventy-six patients (25.7%) remained in mixed circulation. Cumulative risk estimate of death was 10.9%, 16.1%, 16.9%, and 18.8% at 1, 6 months, 1 year, and 5 years, respectively. Tricuspid valve Z-score was inversely, and coronary atresia positively associated with death or transplantation [odds ratio (OR) = 0.46, (95% confidence interval (CI) = 0.29-0.75, p < 0.001) and OR = 3.75 (95% CI 1.46-9.61, p = 0.011), respectively]. Right ventricular coronary dependency and left coronary atresia had a significant effect on transplant-free survival (log-rank p < 0.001). In a contemporary multicenter cohort of patients with PAIVS, consisting predominantly of patients with moderate-to-severe right ventricular hypoplasia, we observed favorable survival outcomes. Right ventricular coronary dependency and left, but not right, coronary atresia significantly worsens transplant-free survival.
RESUMO
Pediatric mechanical circulatory support can be lifesaving. However, managing anticoagulation is one of the most challenging aspects of care in patients requiring mechanical circulatory support. Effective anticoagulation is even more difficult in pediatric patients due to the smaller size of their blood vessels, increased turbulent flow, and developmental hemostasis. Recently, viscoelastic testing (VET) has been used as a qualitative measure of anticoagulation efficacy in patients receiving extracorporeal membrane oxygenation (ECMO) and ventricular assist devices (VAD). Thromboelastography (TEG®) and thromboelastometry (ROTEM®) provide a global qualitative assessment of hemostatic function from initiation of clot formation with the platelet-fibrin interaction, platelet aggregation, clot strength, and clot lysis. This review focuses on the TEG®/ROTEM® and important laboratory and patient considerations for interpretation in the ECMO and VAD population. We summarize the adult and pediatric ECMO/VAD literature regarding VET values, VET-platelet mapping, utility over standard laboratory monitoring, and association with outcome measures such as blood product utilization, bleeding, and thrombosis.
RESUMO
BACKGROUND: We aimed to assess the current nutritional practices in postoperative patients with Congenital Heart Disease. METHODS: Cross-sectional electronic survey was sent to members of The Pediatric Cardiac Intensive Care Society. MEASUREMENTS AND MAIN RESULTS: In Total, 52 members of the Pediatric Cardiac Intensive Care Society responded to the survey consisting of 14% paediatric intensivist, 53% paediatric cardiac intensivist, and 33% nurse/nurse practitioner with a median of 10 years of experience. There was an even distribution between intensivist (55%) and dietitian or nutritionist (45%) in nutrition management. Ninety-eight percent of respondents report that they would feed patients on inotropic or vasoactive support. Only 27% of respondents reported using indirect calorimetry in calculating resting energy expenditure which is the current gold standard. Academic hospitals compared to non-academic hospital were most likely to report feeding patients within 24 hours postoperative (p = 0.014). Having a feeding protocol was associated with feeding within 24 hours postoperative (p = 0.014) and associated with >50% goal intake by 48 hours postoperative (p = 0.025). CONCLUSIONS: Substantial variation in feeding practice still exists despite the American Society for Parenteral and Enteral Nutrition guidelines from 2017. Report of institutional established feeding protocol was associated with increased early feeding and reaching goal feeds by 48 hours postoperative. Very few centres reported use of indirect calorimetry in postoperative paediatric cardiac intensive care patients and many respondents lacked knowledge about applications in this population. Additional work to determine optimal feeding pathways and assessment of caloric needs in this population is needed.
