From Bridge to Destination? Ethical Considerations Related to Withdrawal of ECMO Support over the Objections of Capacitated Patients

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.

Withdrawing extra corporeal membrane oxygenation (ECMO) against a family's wishes: Three permissible scenarios

The ethical permissibility of unilaterally withdrawing life-sustaining technologies has been a perennial topic in transplant and critical care medicine, often focusing on CPR and mechanical ventilation. The permissibility of unilateral withdrawal of extracorporeal membrane oxygenation (ECMO) has been discussed sparingly. When addressed, authors have appealed to professional authority rather than substantive ethical analysis. In this Perspective, we argue that there are at least three (3) scenarios wherein healthcare teams would be justified in unilaterally withdrawing ECMO, despite the objections of the patient's legal representative. The ethical considerations that provide the groundwork for these scenarios are, primarily: equity, integrity, and the moral equivalence between withholding and withdrawing medical technologies. First, we place equity in the context of crisis standards of medicine. After this, we discuss professional integrity as it relates to the innovative usage of medical technologies. Finally, we discuss the ethical consensus known at the "equivalence thesis." Each of these considerations include a scenario and justification for unilateral withdrawal. We also provide three (3) recommendations that aim at preventing these challenges at their outset. Our conclusions and recommendations are not meant to be blunt arguments that ECMO teams wield whenever disagreement about the propriety of continued ECMO support arises. Instead, the onus will be on individual ECMO programs to evaluate these arguments and decide if they represent sensible, correct, and implementable starting points for clinical practice guidelines or policies.
