Ethical and end of life considerations for neonates requiring ECMO support

Formal Ethics Consultation in Extracorporeal Membrane Oxygenation Patients: A Single-Center Retrospective Cohort of a Quaternary Pediatric Hospital

OBJECTIVE

To examine characteristics associated with formal ethics consultation (EC) referral in pediatric extracorporeal membrane oxygenation (ECMO) cases, and document ethical issues presented.

DESIGN

Retrospective cohort study using mixed methods.

SETTING

Single-center quaternary pediatric hospital.

PATIENTS

Patients supported on ECMO (January 2012 to December 2021).

INTERVENTIONS

We compared clinical variables among ECMO patients according to the presence of EC. We defined optimal cutoffs for EC based on run duration, ICU length of stay (LOS), and sum of procedures or complications. To identify independent explanatory variables for EC, we used a forward stepwise selection multivariable logistic regression model. EC records were thematically characterized into ethical issues.

MEASUREMENTS AND MAIN RESULTS

Of 601 ECMO patients and 225 patients with EC in 10 years, 27 ECMO patients received EC (4.5% of ECMO patients, 12% of all ECs). On univariate analysis, use of EC vs. not was associated with multiple ECMO runs, more complications/procedures, longer ICU LOS and ECMO duration, cardiac admissions, decannulation outcome, and higher mortality. Cutoffs for EC were ICU LOS >52 days, run duration >160 hours, and >6 complications/procedures. Independent associations with EC included these three cutoffs and older age. The model showed good discrimination (area under the curve 0.88 [0.83, 0.93]) and fit. The most common primary ethical issues were related to end-of-life, ECMO discontinuation, and treatment decision-making. Moral distress was cited in 22 of 27 cases (82%).

CONCLUSION

EC was used in 4.5% of our pediatric ECMO cases, with most ethical issues related to end-of-life care or ECMO discontinuation. Older age, longer ICU LOS, prolonged runs, and multiple procedures/complications were associated with greater odds for EC requests. These data highlight our single-center experience of ECMO-associated ethical dilemmas. Historical referral patterns may guide a supported decision-making framework. Future work will need to include quality improvement projects for timely EC, with evaluation of impacts on relevant endpoints.

Between hope and disillusionment: ECMO seen through the lens of nurses working in a neonatal and paediatric intensive care unit

BACKGROUND

Using extracorporeal membrane oxygenation (ECMO) in paediatric and neonatal intensive care units (PICU/NICU) creates ethical challenges and carries a high risk for moral distress, burn out and team conflicts.

AIM

The study aimed to gain a more comprehensive understanding of the underlying factors affecting moral distress when using ECMO for infants and children by examining the attitudes of ECMO nurses.

METHODS

Four focus groups discussions were conducted with 21 critical care nurses working in a Swiss University Children's Hospital. Purposive sampling was adopted to identify research participants. The data were analysed using reflexive thematic analysis.

RESULTS

Unlike "miracle machine" stories in online media reports, specialized nurses working in PICU/NICU expressed both their hopes and fears towards this technology. Their accounts also contained references to events and factors that triggered experiences of moral distress: the unspeakable nature of the death of a child or infant; the seemingly lack of honest and transparent communication with parents; the apparent loss of situational awareness among doctors; the perceived lack of recognition for the role of nurses and the variability in end-of-life decision-making; the length of time it takes doctors to take important treatment decisions; and the resource intensity of an ECMO treatment.

CONCLUSION

The creation of a multidisciplinary moral community with transparent information among all involved health care professionals and the definition of clear treatment goals as well as the implementation of paediatric palliative care for all paediatric ECMO patients should become a priority if we want to alleviate situations of moral distress.

RELEVANCE FOR CLINICAL PRACTICE

The creation of a multidisciplinary moral community, clear treatment goals and the implementation of palliative care for all paediatric ECMO patients are crucial to alleviate situations of moral distress for nurses, and thus to improve provider well-being and the quality of patient care in PICU/NICU.

"Death as the One Great Certainty": ethical implications of children with irreversible cardiorespiratory failure and dependence on extracorporeal membrane oxygenation

Introduction

Advances in medical technology have led to both clinical and philosophical challenges in defining death. Highly publicized cases have occurred when families or communities challenge a determination of death by the irreversible cessation of neurologic function (brain death). Parallels can be drawn in cases where an irreversible cessation of cardiopulmonary function exists, in which cases patients are supported by extracorporeal cardiopulmonary support, such as extracorporeal membrane oxygenation (ECMO).

Analysis

Two cases and an ethical analysis are presented which compare and contrast contested neurologic determinations of death and refusal to accept the irreversibility of an imminent death by cardiopulmonary standards. Ambiguities in the Uniform Determination of Death Act are highlighted, as it can be clear, when supported by ECMO, that a patient could have suffered the irreversible cessation of cardiopulmonary function yet still be alive (e.g., responsive and interactive). Parallel challenges with communication with families around the limits of medical technology are discussed.

Discussion

Cases that lead to conflict around the removal of technology considered not clinically beneficial are likely to increase. Reframing our goals when death is inevitable is important for both families and the medical team. Building relationships and trust between all parties will help families and teams navigate these situations. All parties may require support for moral distress. Suggested approaches are discussed.

Extracorporeal Membrane Oxygenation Then and Now; Broadening Indications and Availability

Extracorporeal membrane oxygenation (ECMO) is a life support technology provided to children to support respiratory failure, cardiac failure, or cardiopulmonary resuscitation after failure of conventional management. Over the decades, ECMO has expanded in use, advanced in technology, shifted from experimental to a standard of care, and evidence supporting its use has increased. The expanded ECMO indications and medical complexity of children have also necessitated focused studies in the ethical domain such as decisional authority, resource allocation, and equitable access.

Supporting and Contextualizing Pediatric ECMO Decision-Making Using a Person-Centered Framework

AbstractThere is a critical need to establish a space to engage in careful deliberation amid exciting, important, necessary, and groundbreaking technological and clinical advances in pediatric medicine. Extracorporeal membrane oxygenation (ECMO) is one such technology that began in pediatric settings nearly 50 years ago. And while not void of medical and ethical examination, both the symbolic progression of medicine that ECMO embodies and its multidimensional challenges to patient care require more than an intellectual exercise. What we illustrate, then, is a person-centered framework that incorporates the philosophy and practice of palliative care and care-based ethical approaches. This person-centered framework is valuable for identifying and understanding challenges central to ECMO, guides collaborative decision-making, and recognizes the value of relationships within and between patients, families, healthcare teams, and others who impact and are impacted by ECMO. Specifically, this person-centered approach enables caregivers to provide compassionate and effective support in critical, and often urgent, situations where conflicts may emerge among healthcare team members, families, and other decision makers. By reflecting on three cases based on actual situations, we apply our person-centered framework and identify those aspects that were utilized in and informed this project. We aim to fill a current gap in the pediatric ECMO literature by presenting a person-centered framework that promotes caregiving relationships among hospitalized critically ill children, families, and the healthcare team and is supported through the philosophy and practice of palliative care and clinical ethics.

Extracorporeal membrane oxygenation as a bridge to transplant in neonates with fatal pulmonary conditions: A review

Neonates with progressive respiratory failure should be referred early for subspecialty evaluation and lung transplantation consideration. ECMO should be considered for patients with severe cardiopulmonary dysfunction and a high likelihood of death while on maximal medical therapy, either in the setting of reversible medical conditions or while awaiting lung transplantation. While ECMO offers hope to neonates that experience clinical deterioration while awaiting transplant, the risks and benefits of this intervention should be considered on an individual basis. Owing to the small number of infant lung transplants performed yearly, large studies examining the outcomes of various bridging techniques in this age group do not exist. Multiple single-centre experiences of transplanted neonates have been described and currently serve as guidance for transplant teams. Future investigation of outcomes specific to neonatal transplant recipients bridged with advanced devices is needed.

Extracorporeal Membrane Oxygenation Candidacy Decisions: An Argument for a Process-Based Longitudinal Approach

Are all children extracorporeal membrane oxygenation (ECMO) candidates? Navigating ECMO decisions represents an enormous challenge in pediatric critical care. ECMO cannulation should not be a default option as it will not confer benefit for "all" critically ill children; however, "all" children deserve well-considered decisions surrounding their ECMO candidacy. The complexity of the decision demands a systematic, "well-reasoned" and "dynamic" approach. Due to clinical urgency, this standard cannot always be met prior to initiation of ECMO. We challenge the paradigm of "candidacy" as a singular decision that must be defined prior to ECMO initiation. Rather, the determination as to whether ECMO is in the patient's best interest is applicable regardless of cannulation status. The priority should be on collaborative, interdisciplinary decision-making processes aligned with principles of transparency, relevant reasoning, accountability, review, and appeal. To ensure a robust process, it should not be temporally constrained by cannulation status. We advocate that this approach will decrease both the risk of not initiating ECMO in a patient who will benefit and the risk of prolonged, nonbeneficial support. We conclude that to ensure fair decisions are made in a patient's best interest, organizations should develop procedurally fair processes for ECMO decision-making that are not tied to a particular time point and are revisited along the management trajectory.

Finishing Well: Compassionate Extracorporeal Membrane Oxygenation Discontinuation

Extracorporeal Membrane Oxygenation (ECMO) is associated with significant mortality. Provision of high-quality end-of-life (EOL) care for patients supported on ECMO entails specific physiological, pharmacological, and technical considerations. Limited guidance exists for clinicians on delivery of optimal EOL care on ECMO. In this article, we review the unique aspects of EOL care as they apply to ECMO support and propose a pragmatic, interdisciplinary framework for compassionate ECMO discontinuation in children and adults. The goal of compassionate ECMO discontinuation (CED) is to allow natural death from the underlying disease process while delivering high-quality EOL care to ensure a good death experience for patients and their families. The CED approach includes: 1) a family meeting to define goal-concordant EOL care and prepare families and patients for the dying process; 2) clinical preparation, including symptom management and discontinuation of other life-sustaining therapies; 3) technical aspects which necessarily vary according to patient factors and the circuit and cannulation strategy; and 4) bereavement support. The proposed CED considerations and checklist may serve as tools aiding provision of comprehensive, quality, individualized patient- and family-centered care for children and adults dying despite ECMO support. A structured CED may enhance EOL experiences for patients, family, and staff by providing a respectful and dignified death experience. Future research is required to determine feasibility and effectiveness of the framework, which must be adapted to the patient and institutional setting.

The Meaning Given to Bioethics as a Source of Support by Physicians Who Care for Children Who Require Long-Term Ventilation

The role and potential of bioethics input when a child requires the initiation of technology dependence to sustain life is relatively unknown. In particular, little is understood about the meaning physicians give to bioethics as a source of support during the care of children in pediatric intensive care who require long-term ventilation (LTV). We used a hermeneutic phenomenological approach to underpin the collection and analysis of data. Unstructured interviews of 40 physicians in four countries took place during 2020. We found that elements of trust, communication and acceptance informed the physicians' perceptions of the relationship with bioethics. These ranged from satisfaction to disappointment with their input into critical decisions. Bioethics services have potential to help physicians gain clarity over distressing and complex care decisions, yet physicians perceive the service inconsistently as a means of support. This research provides a sound basis to guide more beneficial interactions between clinicians and bioethics services.

When is enough, enough? Exploring ethical and team considerations in paediatric cardiac care dilemmas

PURPOSE OF REVIEW

Therapies for paediatric congenital and acquired heart disease continue to evolve and the appropriateness of pursuing life sustaining interventions at margins of standard therapy is ethically challenging.

RECENT FINDINGS

With ongoing emphasis on shared decision making, recent literature explored physician and parental perspectives on communication with families and offering interventions for complex congenital heart disease and advanced heart failure. The inclusion of parental values and views in this process is now widely accepted. Identified outstanding challenges include difficulty with prognostication from the outset, adjusting long-term goals of care to changes in clinical parameters, need for consistency in communication including regular review meetings with family or surrogate decision-makers. Bioethics consultation and multidisciplinary team reviews may be helpful supports. Palliative care involvement in this population improves quality of life and alleviates parental distress but this collaboration is not optimized.

SUMMARY

Decision to offer, forgo, or discontinue life-sustaining therapies for children with heart disease has nuanced and context-specific considerations, and must integrate burdens of interventions with patient and family values. Thus, decision making remains complex and demands thoughtful review of not only risks and benefits, but views and values, clearly communicated to team and family.

Ethical Considerations in Ever-Expanding Utilization of ECLS: A Research Agenda

Technological advancements and rapid expansion in the clinical use of extracorporeal life support (ECLS) across all age ranges in the last decade, including during the COVID-19 pandemic, has led to important ethical considerations. As a costly and resource intensive therapy, ECLS is used emergently under high stakes circumstances where there is often prognostic uncertainty and risk for serious complications. To develop a research agenda to further characterize and address these ethical dilemmas, a working group of specialists in ECLS, critical care, cardiothoracic surgery, palliative care, and bioethics convened at a single pediatric academic institution over the course of 18 months. Using an iterative consensus process, research questions were selected based on: (1) frequency, (2) uniqueness to ECLS, (3) urgency, (4) feasibility to study, and (5) potential to improve patient care. Questions were categorized into broad domains of societal decision-making, bedside decision-making, patient and family communication, medical team dynamics, and research design and implementation. A deeper exploration of these ethical dilemmas through formalized research and deliberation may improve equitable access and quality of ECLS-related medical care.

Postcardiotomy Extracorporeal Membrane Oxygenation: Narrative Review Navigating the Ethical Issues

Postcardiotomy shock (PCS) is an uncommon and life-threatening surgical complication. Extracorporeal membrane oxygenation (ECMO) is the first line of mechanical circulatory support for treating PCS when medical therapies are insufficient. Reaching a "therapeutic ceiling" or a "bridge to nowhere" is a common clinical scenario in which medical avenues for recovery have been exhausted. These situations pose emotional and ethical challenges for patients, their surrogates, and clinicians. To shed light on these ethically challenging situations in PCS and potential approaches, the authors conducted a narrative review of the literature. Publications were utilized to describe current trends in the diagnosis and management of the patient with PCS, with particular emphasis on the therapeutic ceiling for life support. Most of the recommendations came from practice parameters or expert opinions to support specific interventions. The authors proposed a stepwise multidisciplinary approach to reduce PCS-associated ethical and emotional challenges. Their proposed algorithm was based on the likelihood of the need for ECMO support based on the mortality risk stratification of cardiac surgery. They suggested focused discussions around the commencement of ECMO or other life-sustaining therapies-ideally preoperatively at the time of consent-through shared decision-making and, subsequently, proactive multidisciplinary education and updates to the surrogate decision-makers relying on realistic prognosis and consideration of the patient wishes during the ECMO run.

Ethical challenges with decisions to withhold or withdraw resuscitation in pediatric surgery

Providers often dispute the ethical equivalence of withholding and withdrawing care, despite theoretical frameworks that support equivalency. We highlight two cases, one where providers express concern with initiation of aggressive resuscitation and another where providers experience emotional distress from the decision to cease resuscitation. Both cases illustrate how the ethical challenges encountered can result in high levels of provider distress. Mitigation of this moral distress by team members will require an improved understanding of available evidence in the literature and active discussion by debriefing after a child dies. Medical staff and national organizations can help recognize that these patient events contribute to provider burnout and facilitate the design and support of programs to increase provider resiliency.

Decision-Making, Ethics, and End-of-Life Care in Pediatric Extracorporeal Membrane Oxygenation: A Comprehensive Narrative Review

OBJECTIVES

Pediatric extracorporeal membrane oxygenation is associated with significant morbidity and mortality. We sought to summarize literature on communication and decision-making, end-of-life care, and ethical issues to identify recommended approaches and highlight knowledge gaps.

DATA SOURCES

PubMed, Embase, Web of Science, and Cochrane Library.

STUDY SELECTION

We reviewed published articles (1972-2020) which examined three pediatric extracorporeal membrane oxygenation domains: 1) decision-making or communication between clinicians and patients/families, 2) ethical issues, or 3) end-of-life care.

DATA EXTRACTION

Two reviewers independently assessed eligibility using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology.

DATA SYNTHESIS

Of 2,581 publications screened, we identified one systematic review and 35 descriptive studies. No practical guides exist for communication and decision-making in pediatric extracorporeal membrane oxygenation. Conversation principles and parent/clinician perspectives are described. Ethical issues related to consent, initiation, discontinuation, resource allocation, and research. No patient-level synthesis of ethical issues or end-of-life care in pediatric extracorporeal membrane oxygenation was identified.

CONCLUSIONS

Despite numerous ethical issues reported surrounding pediatric extracorporeal membrane oxygenation, we found limited patient-level research and no practical guides for communicating with families or managing extracorporeal membrane oxygenation discontinuation.

A Communication Guide for Pediatric Extracorporeal Membrane Oxygenation

Decision-making surrounding extracorporeal membrane oxygenation initiation and decannulation has become a key challenge in critical care. Nuanced communication skills and transparent discussions about prognosis are imperative during this lifesaving, yet high-risk and burdensome intervention. Serious illness conversation guides are proving beneficial for patients, families and staff to communicate uncertainty and facilitate shared decision-making toward goal-concordant care. While the literature emphasizes the imperative to provide guidance for clinicians, no practical guide exists for communicating serious illness and prognostic uncertainty when managing children supported with extracorporeal membrane oxygenation and their families. To address this gap, we propose a structured conversation guide for critical early timepoints during pediatric extracorporeal membrane oxygenation support relevant for all cannulations and subsequent iterative discussions toward decannulation. The overarching approach defines extracorporeal membrane oxygenation as a bridge or temporary support device, part of a larger therapeutic effort toward a specific goal or goals. The Day 0 talk at extracorporeal membrane oxygenation initiation is brief, disclosing the serious nature of needing this level of support, and sets clear expectations toward a goal. The Day 1 talk provides further details about benefits and burdens of extracorporeal membrane oxygenation, cultivates prognostic awareness about potential outcomes and elicits families' goals of care with iterative discussions about how extracorporeal membrane oxygenation may promote these goals. If extracorporeal membrane oxygenation is no longer effective to achieve the intended goal, recommendations are provided for discontinuation of support. When death is anticipated or possible, end-of-life planning, contingencies, and escalation limits should be discussed. The communication framework presented can be adapted to unique institutional and clinical settings. Future research is required to investigate utility and potential barriers to implementation. We anticipate that structured conversations during extracorporeal membrane oxygenation support will facilitate clear expectations toward a common treatment goal, foster therapeutic relationships, ensure clinician alignment and consistent language, mitigate communication gaps, support bereavement, and minimize conflict.

Nurses' experience of patient care using extracorporeal membrane oxygenation

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is an advanced form of temporary life support, to aid respiratory and/or cardiac function, which diverts venous blood through an extracorporeal circuit and returns it to the body after gas exchange through a semipermeable membrane. It may be used for oxygenation, carbon dioxide removal, and hemodynamic support. ECMO has been available to patients in Iran for only about 4 years. Because nurses do not widely use ECMO in Intensive Care Units (ICUs), for many it is still a unique experience and more needs to be understood about that experience in order to support nurses in that role.

AIM

This study aimed to explore Iranian nurses' experience of caring for patients receiving ECMO.

METHODS

This interpretive phenomenological study was conducted in Iran in 2019. Semi-structured interviews were conducted in Farsi to collect data from 18 nurses who had cared for patients receiving ECMO. The interviews continued until data saturation, and thematic analysis of the interview transcripts was undertaken.

RESULTS

Following thematic analysis, three main themes of "running on a suspension bridge," "sense of duality," and "bewilderment in the mirage of hope," and with seven sub-themes, emerged.

CONCLUSION

Based on the results of this study, it is proposed that caring for patients receiving ECMO is a source of emotional turmoil for nurses. Nurses are constantly thinking about whether their patients receiving ECMO are recovering or dying, and the nature of this care may lead to stress and burnout. Therefore, it is recommended that these nurses receive counselling and psychological support.

RELEVANCE TO CLINICAL PRACTICE

Nurses are able to provide comprehensive and holistic patient care when they enjoy good physical and mental health themselves. To prevent distress in nurses and to provide safe care for the patient receiving ECMO, provision of psychological support for these nurses is recommended.

Ethics in extracorporeal life support: a narrative review

During 50 years of extracorporeal life support (ECLS), this highly invasive technology has left a considerable imprint on modern medicine, and it still confronts researchers, clinicians and policymakers with multifarious ethical challenges. After half a century of academic discussion about the ethics of ECLS, it seems appropriate to review the state of the argument and the trends in it. Through a comprehensive literature search on PubMed, we identified three ethical discourses: (1) trials and evidence accompanying the use of ECLS, (2) ECLS allocation, decision-making and limiting care, and (3) death on ECLS and ECLS in organ donation. All included articles were carefully reviewed, arguments extracted and grouped into the three discourses. This article provides a narrative synthesis of these arguments, evaluates the opportunities for mediation and substantiates the necessity of a shared decision-making approach at the limits of medical care.

Variation in Pediatric Palliative Care Allocation Among Critically Ill Children in the United States

OBJECTIVES

The objectives are as follows: 1) estimate palliative care consult rates and trends among critically ill children and 2) characterize which children receive palliative care consults, including those meeting previously proposed ICU-specific palliative care screening criteria.

DESIGN

Retrospective cohort.

SETTING

Fifty-two United States children's hospitals participating in the Pediatric Health Information Systems database.

PATIENTS

Hospitalized children with nonneonatal ICU admissions from 2007 to 2018.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was palliative care consultation, as identified by the palliative care International Classification of Disease code. Patient characteristics and outcomes were compared between those with and without palliative care. We used a mixed-effects multivariable model to estimate the independent association between the palliative care and patient characteristics accounting for institution and subject clustering. Hospitalizations were categorized into three mutually exclusive groups for comparative analyses: 1) meeting ICU-specific palliative care criteria, 2) presence of a complex chronic condition not in ICU-specific palliative care criteria, or 3) not meeting ICU-specific palliative care or complex chronic condition criteria. Rates and trends of palliative care consultation were estimated including variation among institutions and variation among subcategories of ICU-specific palliative care criteria. The study cohort included 740,890 subjects with 1,024,666 hospitalizations. About 1.36% of hospitalizations had a palliative care consultation. Palliative care consult was independently associated with older age, female sex, government insurance, inhospital mortality, and ICU-specific palliative care or complex chronic condition criteria. Among the hospitalizations, 30% met ICU-specific palliative care criteria, 40% complex chronic condition criteria, and 30% neither. ICU-specific palliative care patients received more mechanical ventilation and cardiopulmonary resuscitation, had longer hospital and ICU lengths of stay, and had higher inhospital mortality (p < 0.001). Palliative care utilization increased over the study period with considerable variation between the institutions especially in the ICU-specific palliative care cohort and its subgroups.

CONCLUSIONS

Palliative care consultation for critically ill children in the United States is low. Palliative care utilization is increasing but considerable variation exists across institutions, suggesting inequity in palliative care allocation among this vulnerable population. Future studies should evaluate factors influencing allocation of palliative care among critically ill children in the United States and the drivers of differences between the institutional practices.

Use of Extracorporeal Membrane Oxygenation After Congenital Heart Disease Repair: A Systematic Review and Meta-Analysis

Introduction: Extracorporeal membrane oxygenation (ECMO) has been widely used to treat cardiopulmonary failure in patients with congenital heart defects (CHD) postoperatively. A meta-analysis is performed for outcomes of postoperative CHD patients on ECMO.

Methods: Electronic databases, including PubMed, EMbase, and Cochrane Library CENTRAL were searched systematically from January 1990 to June 2020 for literature which reported the outcomes of postoperative CHD cases on ECMO. The scope of this search was restricted to articles published in English.

Results: Forty-three studies were included in this study, involving 3,585 subjects. Postoperative ventricular failure with low cardiac output was the most common indication of ECMO initiation. The pooled estimated incidence of in-hospital mortality was 56.8% (95% CI, 52.5–61.0%). Bleeding was the most common complication with ECMO with an incidence of 47.1% (95% CI, 38.5–55.8%). Multivariate meta-regression analysis revealed that single ventricular physiology (coefficient 0.213, 95% CI 0.099–0.327, P = 0.001) and renal failure (coefficient 0.315, 95% CI 0.091–0.540, P = 0.008) were two independent risk factors for in-hospital mortality.

Conclusions: There is an overall high in-hospital mortality of 56.8% in postoperative CHD patients on ECMO. Bleeding is the most common complication during ECMO running with an incidence of 47.1%. Single ventricular physiology and renal failure, as two independent risk factors, may potentially increase in-hospital mortality. Further studies exploring the differences in outcomes between ECMO and other extracorporeal life support strategies are warranted.

Emerging issues in the ethical utilization of pediatric extracorporeal membrane oxygenation

PURPOSE OF REVIEW

As we have refined our extracorporeal membrane oxygenation (ECMO) capabilities and enhanced our ability to care for children with illnesses previously deemed lethal, the patient populations for whom ECMO is a medically appropriate intervention have expanded. Such expansion has prompted consideration of evolving ethical issues. In this review, we highlight several of the emerging ethical issues in pediatric ECMO.

RECENT FINDINGS

Expansion of ECMO into increasingly diverse pediatric populations has prompted several ethical questions. First, some have found that there are specific clinical settings in which ECMO ought to be obligatory. Second, expanded use of ECMO may prompt disagreements among healthcare providers or between providers and family members regarding decisions about decannulation. Finally, analysis of the ethical challenges associated with integration of other disruptive healthcare modalities into patient care, will allow us insight into how to assure ethical expansion of pediatric ECMO.

SUMMARY

Expansion of pediatric ECMO highlights several ethical issues including whether ECMO is ever ethically obligatory, how to ethically decannulate a patient when survival is deemed unlikely, and how to guide expansion of pediatric ECMO based upon lessons learned from the implementation of other disruptive healthcare interventions into practice.

Principlism and Personalism. Comparing Two Ethical Models Applied Clinically in Neonates Undergoing Extracorporeal Membrane Oxygenation Support

Extracorporeal membrane oxygenation (ECMO) is a technology used to temporarily assist critically ill patients with acute and reversible life-threatening cardiac and/or respiratory failure. This technology can often be lifesaving but is also associated with several complications that may contribute to reduced survival. Currently, neonates supported with ECMO are complex and bear an increased risk of mortality. This means that clinicians must be particularly prepared not only to deal with complex clinical scenarios, but also ethical issues associated with ECMO. In particular, clinicians should be trained to handle unsuccessful ECMO runs with attention to high quality end of life care. Within this manuscript we will compare and contrast the application of two ethical frameworks, used in the authors' institutions (Toronto and Rome). This is intended to enhance a broader understanding of cultural differences in applied ethics which is useful to the clinician in an increasingly multicultural and diverse patient mix.

Palliative Care for Patients With Advanced Heart Disease

Over the past 2 decades, the discipline of palliative care has evolved and expanded such that it is now the standard of care for a variety of acute and chronic processes. Although there are recommendations encouraging incorporation of palliative care into the routine management of patients with chronic cardiac processes, such as congestive heart failure, implementation has been challenging, and nowhere more so than in the cardiac surgical population. However, as the boundaries of surgical care have expanded to include progressively more complex cases, increasing attention has been given to the integration of palliative care into their management. In this review article, the authors describe the existing evidence for palliative care team involvement in patients with non-operative and surgical cardiac diseases and examine future directions for growth in this field.

Establishing and Sustaining an ECPR Program

The use of extracorporeal support after failed return of a spontaneous ciruculation during cardiopulmonary resuscitation (ECPR) is well described. There are 4 distinct phases for resuscitation with ECPR and the time spent in each phase is critical for successful outcome. Recommendations for ECPR previously published by the American Heart Association provide the context for implementing a consistent and well-rehearsed system for ECPR, by people with the knowledge, experience and resources to deploy ECPR in the most optimal time frame possible in selected patient populations. In this manuscript we review the current status of ECPR for acute cardiac failure and the components we believe are necessary to develop and sustain a reliable and resilient program.
