"Bridging the Gap" international ECLS training and simulation - evaluation of the 10th educational corner on EuroELSO congress 2022 in London, United Kingdom.

Introduction: Simulation training offers an authentic team-based learning opportunity without risk to real patients. The Educational Corner at the annual congress of the European Branch of Extracorporeal Life Support Organisation (EuroELSO) provided an opportunity for multiple simulation training sessions facilitated by experts from all over the world.Aim: We aimed to review the educational impact of EuroELSO Educational Corner and whether it provides a quality ECLS training to a wide spectrum of multidisciplinary international attendees utilising high and low fidelity simulation, workshops and hands on sessions.Methods: During the congress, 43 sessions were conducted dedicated to ECLS education with identified educational objectives. The sessions focused on management of adults and children on V-V or V-A ECMO. Adult sessions covered emergencies on mechanical circulatory support with management of LVAD and Impella, managing refractory hypoxemia on V-V ECMO, emergencies on ECMO, renal replacement therapy on ECMO, V-V ECMO, ECPR cannulation and performing perfect simulation. Paediatric sessions covered ECPR neck and central cannulation, renal replacement on ECMO, troubleshooting, cannulation workshop, V-V recirculation, ECMO for single ventricle, PIMS-TS and CDH, ECMO transport and neurological injury.Results: The Educational Corner was attended by more than 400 participants over the two congress days. Majority of responders (88%) reported that training sessions met the set educational goals and objectives and that this would change their current practice. Almost all (94%) reported that they received useful information and 95% would recommend the session to their colleagues.Conclusion: The Educational Corner, as an integral component of the annual EuroELSO congress, achieved the set educational goals and provided quality education based on the recipient survey. Structured multidisciplinary ECLS education with standardised curriculum and feedback is an important key step in delivering quality training to an international audience. Standardisation of European ECLS education remains an important focus of the EuroELSO.

Extracorporeal Life Support Organization Guidelines for the Provision and Assessment of Nutritional Support in the Neonatal and Pediatric ECMO Patient.

DISCLAIMER: This guideline is intended for educational use to build the knowledge of physicians and other health professionals in assessing the conditions and managing the treatment of patients undergoing extracorporeal life support (ECLS)/extracorporeal membrane oxygenation (ECMO) and describe what are believed to be useful and safe practice for extracorporeal life support (ECLS, ECMO) but these are not necessarily consensus recommendations. The aim of clinical guidelines are to help clinicians to make informed decisions about their patients. However, adherence to a guideline does not guarantee a successful outcome. Ultimately, healthcare professionals must make their own treatment decisions about care on a case-by-case basis, after consultation with their patients, using their clinical judgment, knowledge, and expertise. These guidelines do not take the place of physicians' and other health professionals' judgment in diagnosing and treatment of particular patients. These guidelines are not intended to and should not be interpreted as setting a standard of care or be deemed inclusive of all proper methods of care nor exclusive of other methods of care reasonably directed to obtaining the same results. The ultimate judgment must be made by the physician and other health professionals and the patient in light of all the circumstances presented by the individual patient, and the known variability and biologic behavior of the clinical condition. These guidelines reflect the data at the time the guidelines were prepared; the results of subsequent studies or other information may cause revisions to the recommendations in these guidelines to be prudent to reflect new data, but Extracorporeal Life Support Organization (ELSO) is under no obligation to provide updates. In no event will ELSO be liable for any decision made or action taken in reliance upon the information provided through these guidelines.

Childhood Extracorporeal Membrane Oxygenation Survivors: Parents Highlight Need for Structured Follow-Up and Support After Hospital Discharge.

OBJECTIVES: To examine parental experiences of childhood extracorporeal membrane oxygenation survivors to understand: 1) the problems children faced and 2) the support received following hospital discharge. DESIGN: Single-center descriptive study. SETTING: Nationally commissioned center for neonatal and pediatric extracorporeal membrane oxygenation. PATIENTS: All traceable survivors less than 18 years old who received extracorporeal membrane oxygenation from January 1998 to April 2013. INTERVENTION: Anonymized postal questionnaire completed by parents of extracorporeal membrane oxygenation survivors. MEASUREMENTS AND MAIN RESULTS: Parent-reported developmental problems, follow-up, and the degree of satisfaction with any follow-up experience. Parents of 89 of 366 extracorporeal membrane oxygenation survivors (24%) responded. Sixty-six (74%) reported having developmental concerns about their child, including speech and language (n = 32; 36%), concentration (n = 28; 31%), movement/physical difficulties (n = 26; 29%), and educational difficulties (n = 22; 25%); 46 (52%) indicated that their child had difficulties across multiple domains. Twenty-one (34%) of those with one or more reported developmental concerns were not receiving any follow-up. However, 57 (64%) attended our 1-year follow-up extracorporeal membrane oxygenation clinic and 54 of 57 (95%) found it very useful. Three themes related to perceived need were identified from parents' free-text comments: the need for an expert point of contact and follow-up at the extracorporeal membrane oxygenation center; more information on extracorporeal membrane oxygenation and any long-term effects; and more support from, and easier access to, community specialist services. CONCLUSIONS: A proportion of children who have undergone extracorporeal membrane oxygenation treatment have needs that are not being met, with variable access to service provision. Structured follow-up after discharge would enable early identification of developmental concerns, permit early referral or intervention, and provide support to families. Education and sharing of information about extracorporeal membrane oxygenation with general practitioners/family physicians, community professionals, and schools are essential.

Medical missions for the provision of paediatric cardiac surgery in low- and middle-income countries.

This review will outline the role of visiting cardiac surgical teams in low- and middle-income countries drawing on the collective experience of the authors in a wide range of locations. Requests for assistance can emerge from local programmes at a beginner or advanced stage. However, in all circumstances, careful pre-trip planning is necessary in conjunction with clinical and non-clinical local partners. The clinical evaluation, surgical procedures, and postoperative care all serve as a template for collaboration and education between the visiting and local teams in every aspect of care. Education focusses on both common and patient-specific issues. Case selection must appropriately balance the clinical priorities, safety, and educational objectives within the time constraints of trip duration. Considerable communication and practical challenges will present, and clinicians may need to make significant adjustments to their usual practice in order to function effectively in a resource-limited, unfamiliar, and multilingual environment. The effectiveness of visiting trips should be measured and constantly evaluated. Local and visiting teams should use data-driven evaluations of measurable outcomes and critical qualitative evaluation to repeatedly re-assess their interim goals. Progress invariably takes several years to achieve the final goal: an autonomous self-governing, self-financed, cardiac programme capable of providing care for children with complex CHD. This outcome is consistent with redundancy for the visiting trips model at the site, although fraternal, professional, and academic links will invariably remain for many years.

The 1-Year Follow-Up Clinic for Neonates and Children After Respiratory Extracorporeal Membrane Oxygenation Support: A 10-Year Single Institution Experience.

OBJECTIVES: To establish the effectiveness of a "1-year extracorporeal membrane oxygenation follow-up clinic" and to characterize any neurodevelopmental concerns identified. DESIGN: Single-center retrospective cohort of respiratory extracorporeal membrane oxygenation survivors over 10 years. SETTING: Nationally commissioned center for neonatal and pediatric (> 28 d of life) respiratory extracorporeal membrane oxygenation. PATIENTS: Children attending the follow-up clinic 1 year after receiving respiratory extracorporeal membrane oxygenation between 2003 and 2013. INTERVENTIONS: Standardized follow-up 1 year after extracorporeal membrane oxygenation. MEASUREMENTS AND MAIN RESULTS: In 10 years, 290 children received extracorporeal membrane oxygenation, 194 (67%) survived; all were offered 1-year follow-up, and 98 (51%) attended the clinic. Among these, 51 of 98 (52%) had meconium aspiration syndrome, and 74 of 98 (75%) were on veno-arterial extracorporeal membrane oxygenation with a median (interquartile range) duration of 6 days (4-8 d). Neurodevelopmental problems were identified in 30 of 98 (30%). The specific abnormalities noted included neurologic (seizures, motor, or vision abnormalities) (n = 8), hearing with/without language delay (n = 8), and behavioral problems (as reported by parents) (n = 6), with eight of 30 (27%) having difficulties spanning these domains. An acute neurologic event on extracorporeal membrane oxygenation was found to be the only risk factor for neurodevelopmental concerns (p = 0.006 with odds ratio 5.4 [95% CI, 1.63-17.92]). Despite having neither a cardiac arrest nor an acute neurologic event documented, 18 of 74 (24.3%), 95% CI (15.1-35.7), had neurodevelopmental concerns at 1-year follow-up. Among the nonattenders, 30 (15%) had local follow-up, and 66 (34%) were lost to follow-up. CONCLUSIONS: All extracorporeal membrane oxygenation survivors need follow-up either at the extracorporeal membrane oxygenation center or in their community, as evidenced by the 1-year follow-up data. Our 1-year extracorporeal membrane oxygenation follow-up clinic provides an opportunity to engage with families, identify neurodevelopmental concerns, and signpost to appropriate services. Of concern, one third of survivors are lost to follow-up, some with an acute neurologic event on extracorporeal membrane oxygenation, a significant risk factor. A consensus-based standardized national follow-up program is vital.

Predictors and Outcome of Extracorporeal Life Support After Pediatric Heart Transplantation.

BACKGROUND: Extracorporeal life support (ECLS) has proven success after conventional cardiac surgery. Its use after pediatric heart transplantation is less well documented. We reviewed ECLS after pediatric heart transplantation, to understand better predisposing factors, morbidity, and mortality. METHODS: The notes of all patients at Great Ormond Street Hospital undergoing orthotopic heart transplantation from 1999 to 2009 were reviewed (202 transplants; patients aged 0.06 to 17.91 years). Patients were grouped by diagnosis: restrictive cardiomyopathy (n = 17), nonrestrictive cardiomyopathy (n = 134), and anatomic heart disease (n = 51). RESULTS: Twenty-eight patients (13.9%) required ECLS after transplantation. Those requiring ECLS had longer ischemic times (4.2 versus 3.7 hours, p = 0.02). More restrictive cardiomyopathy patients (35.3%) required ECLS-higher than dilated cardiomyopathy (10.4%) or anatomic heart disease (15.7%; χ(2) 7.99; p = 0.018). Factors associated with posttransplant ECLS were restrictive cardiomyopathy, longer ischemic time, and extracorporeal membrane oxygenation before transplant. Graft survival was higher in the non-ECLS group, with 1-year survival of 98.2% versus 57.7%; however, medium-term survival was comparable, with 5-year survival for those surviving to hospital discharge being 84.7% versus 100%. CONCLUSIONS: The requirement for ECLS was higher than expected for conventional cardiac surgery. Although just over one half of patients requiring ECLS survived to discharge, they had excellent medium-term survival, with all still alive. Although ECLS is an expensive, invasive therapy, with significant morbidity and mortality, without it, those patients would have perished. Its judicious use, therefore, can be recommended.

Parental symptoms of posttraumatic stress after pediatric extracorporeal membrane oxygenation*.

OBJECTIVE: To investigate the prevalence of posttraumatic stress symptoms in parents of children who have been supported on extracorporeal membrane oxygenation and to explore associated factors. DESIGN: Descriptive cross-sectional study. SETTING: A specialist pediatric tertiary center in the United Kingdom. SUBJECTS: Parents (n = 52) of children who had been supported with extracorporeal membrane oxygenation at least 6 months previously. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Self-reported questionnaires were completed measuring posttraumatic stress symptom, family functioning, depression, anxiety, and demographic variables. Approximately 20% of parents experienced posttraumatic stress symptoms at levels suggestive of a diagnosis of posttraumatic stress disorder, irrespective of the time that had elapsed since extracorporeal membrane oxygenation. Although having a child who had ongoing illness before extracorporeal membrane oxygenation was associated with avoidance posttraumatic stress symptoms, results suggest that other previously identified risk factors, such as gender and family functioning, may not be risk factors for posttraumatic stress symptom in this population. CONCLUSIONS: A substantial number of parents in this population experience posttraumatic stress symptom. Psychological interventions may be targeted toward those whose child has had ongoing illness before extracorporeal membrane oxygenation.

Long-term survival outcomes and causes of late death in neonates, infants, and children treated with extracorporeal life support.

OBJECTIVES: Extracorporeal life support is a resource-intense treatment offered to the sickest patients. We aimed to investigate long-term survival rates and late deaths. DESIGN: Retrospective cohort study. SETTING: Tertiary referral center for extracorporeal life support. PATIENTS: All patients who required extracorporeal life support from 1992 to 2010 at our center. The U.K. National Health Service number was used to trace survival status of all patients who received extracorporeal life support at our center, grouped by diagnosis. Death more than 90 days after extracorporeal life support was defined as late, and these medical records were reviewed. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 741 children with 272 early deaths (36.7%) and 46 late deaths (6.2%) were included. Median follow-up time in survivors was 7.1 (interquartile range, 3.0-11.9) years. Five-year survival estimates were highest for meconium aspiration syndrome 88.0% (95% CI, 80.6-92.7%) and lowest for congenital heart disease 32.3% (95% CI, 25.1-39.8%). Five-year survival estimates conditional on being alive at 90 days were highest for meconium aspiration syndrome 97.9% (95% CI, 92.0-99.5%) and lowest for congenital diaphragmatic hernia 73.6% (52.3-86.5%). There was increased risk of late death in congenital diaphragmatic hernia, congenital heart disease, and acquired heart disease (p < 0.001, p < 0.01, p = 0.01) in comparison with the risk in meconium aspiration syndrome. For 46 late deaths, 17 had a cardiac cause, 16 had a respiratory cause, 10 had a comorbid cause, one died of sepsis, and in two, causation was unknown. CONCLUSIONS: Although the majority of deaths were early, late mortality was observed following extracorporeal life support. Late deaths were more prevalent in children with underlying complex long-term conditions, particularly heart disease and congenital diaphragmatic hernia. Evaluation of longer term survival is an important component of audit for extracorporeal life support outcomes.

Healthcare-associated infection in pediatric patients on extracorporeal life support: The role of multidisciplinary surveillance.

OBJECTIVE: To describe the use of a multidisciplinary approach to sepsis surveillance and evaluate impact on outcome. DESIGN: Prospective clinical study or clinical audit cycle. SETTING: Tertiary pediatric extracorporeal membrane oxygenation (ECMO) center. PATIENTS: Patients were 215 children supported with ECMO January 1999 to December 2004. INTERVENTIONS: A multidisciplinary team met monthly to evaluate cases of bloodstream infection and mediastinitis, review trends, and update unit policies. Changes in practice were made at the end of 2001 in order to address a perceived high rate of sepsis: a) reeducation; b) introduction of electively preprimed ECMO circuits; and c) preference for neck rather than chest cannulation in cardiac patients. Prophylactic antibiotics were used from preprocedure for 24 hrs only throughout the study. MEASUREMENTS AND MAIN RESULTS: Over the entire study period, 39 children had 47 septic episodes, with a rate of 24.9 per 1000 ECMO days. Multiple logistic regression analyses indicated that infection was associated with duration of ECMO support (odds ratio 1.24; 95% confidence interval 1.15, 1.35 per day) and case type: Closed vs. open chest was protective in cardiac patients (odds ratio 0.08; 95% confidence interval 0.01, 0.50). Infection increased the odds of death by 2.01 (95% confidence interval 1.00, 4.05), but this effect was less important than case type and ECMO days. After policy changes were implemented, there was a reduction in sepsis from 29.3 to 20.1 episodes per 1000 ECMO days. There was reduced sepsis in respiratory patients: neonates from 28.0 to 6.6 and pediatric patients from 42.4 to 16.9 episodes per 1000 ECMO days. Despite policy changes, sepsis remained a problem in cardiac patients with open sternum: 65.1 per 1000 ECMO days. CONCLUSIONS: ECMO support is a high-risk setup for nosocomial infection, in particular for cardiac patients with open sternum for whom antibiotic prophylaxis is justified. Multidisciplinary surveillance offers an excellent approach for quality improvement in this challenging field.

A wet-primed extracorporeal membrane oxygenation circuit with hollow-fiber membrane oxygenator maintains adequate function for use during cardiopulmonary resuscitation after 2 weeks on standby.

OBJECTIVE: To assess the durability of wet-preprimed extracorporeal membrane oxygenation (ECMO) circuits for potential use in resuscitation after a 2-wk period of storage. DESIGN: Experimental laboratory study. SETTING: Tertiary care pediatric cardiac intensive care unit. SUBJECTS: None. INTERVENTIONS AND MEASUREMENTS: 14 ECMO circuits (polyvinyl chloride and super-Tygon tubing with hollow-fiber oxygenator, Medos Hilite 800LT) were primed with crystalloid under sterile conditions and stored for 0 (control, n = 4), 7 (n = 5) and 14 (n = 5) days and maintained at 8 degrees C on pump at 10 rpm and gas flow at 0.2 L/min. Daily samples were inspected for plasticizers by means of high-performance liquid chromatography and for microorganisms by culture and polymerase chain reaction techniques. After storage, the oxygenators were primed with red blood cells (hemoglobin, 12 g/dL) and tested in vitro with a deoxygenator according to Association for Advancement of Medical Instrumentation standards. Oxygen and CO(2) transfer rates were calculated by standard formulae at maximum blood flow (800 mL/min) and maximum sweep gas flow (1.6 L/min). MAIN RESULTS: Oxygen transfer was linearly related to venous oxygen saturation, increasing by 11 mL/min for each 10% decrease in venous oxygen saturation. Estimated oxygen transfer at venous oxygen saturation of 60% was 45.8 mL/min (95% confidence interval [CI], 43.5-48.1) for controls, 51.0 mL/min (95% CI, 48.9-53.2) for 7-day oxygenators, and 49.0 mL/min (95% CI, 47.8-50.1) for 14-day oxygenators. CO(2) transfer declined to 29.2 mL/min at 14 days of storage, a mean fall of 11.5 mL/min (95% CI, 4.2-18.7) in comparison with 7-day storage. All circuits were free from microbes/microbial DNA. Plasticizer levels fell below the lower limit of detection (0.003 microg/mL) at 7 and 14 days. CONCLUSIONS: A wet-preprimed ECMO circuit with hollow-fiber membrane oxygenator can be stored for up to 2 wks with adequately preserved function if prepared appropriately. These data may improve safe access to rapid-response ECMO support.

Plasticizer di(2-ethylhexyl)phthalate (DEHP) release in wet-primed extracorporeal membrane oxygenation (ECMO) circuits.

A wet-primed ready-to-use extracorporeal membrane oxygenation (ECMO) circuit is used in some centres for rapid deployment of ECMO during cardiopulmonary resuscitation. Yet, the potential release of plasticizer di(2-ethylhexyl)phthalate (DEHP) from the polyvinyl chloride tubing in the circuit during storage is a concern. In this study, a high performance liquid chromatography method was used to determine the concentration of DEHP in the priming solution (Plasmalyte) from an ECMO circuit stored for up to 14 days at 8 degrees C. No accumulation of DEHP in the circulating fluid was detected. The results provide important information for centres where ECMO circuits are kept wet-primed prior to clinical use.
