Terminal withdrawal of mechanical ventilation in adult intensive care units: A systematic review and narrative synthesis of perceptions, experiences and practices

BACKGROUND

During the terminal withdrawal of life-sustaining measures for intensive care patients, the removal of respiratory support remains an ambiguous practice. Globally, perceptions and experiences of best practice vary due to the limited evidence in this area.

AIM

To identify, appraise and synthesise the latest evidence around terminal withdrawal of mechanical ventilation in adult intensive care units specific to perceptions, experiences and practices.

DESIGN

Mixed methods systematic review and narrative synthesis. A review protocol was registered on PROSPERO (CRD42018086495).

DATA SOURCES

Four electronic databases were systematically searched (Medline, Embase, CENTRAL and CINAHL). Obtained articles published between January 2008 and January 2020 were screened for eligibility. All included papers were appraised using relevant appraisal tools.

RESULTS

Twenty-five papers were included in the review. Findings from the included papers were synthesised into four themes: 'clinicians' perceptions and practices'; 'time to death and predictors'; 'analgesia and sedation practices'; 'physiological and psychological impact'.

CONCLUSIONS

Perceptions, experiences and practices of terminal withdrawal of mechanical ventilation vary significantly across the globe. Current knowledge highlights that the time to death after withdrawal of mechanical ventilation is very short. Predictors for shorter duration could be considered by clinicians and guide the choice of pharmacological interventions to address distressing symptoms that patients may experience. Clinicians ought to prepare patients, families and relatives for the withdrawal process and the expected progression and provide them with immediate and long-term support following withdrawal. Further research is needed to improve current evidence and better inform practice guidelines.

Medicine, Technology, and Religion Reconsidered: The Case of Brain Death Definition in Israel

The introduction of respiratory machines in the 1950s may have saved the lives of many, but it also challenged the notion of death itself. This development endowed “machines” with the power to form a unique ontological creature: a live body with a “dead” brain. While technology may be blamed for complicating things in the first place, it is also called on to solve the resulting quandaries. Indeed, it is not the birth of the “brain-dead” that concerns us most, but rather its association with a web of epistemological and ethical considerations, where technology plays a central role. The brain death debate in Israel introduces highly sophisticated religious thought and authoritative medical expertise. At focus are the religious acceptance and rejection of brain death by a technologically savvy group of rabbis whose religious doctrine––along with a particular form of religious reasoning––is used to support the truth claims made from the scientific community (brain death is death) but challenge the ways in which they are made credible (instrumental rather than clinical). In our case, brain death as “true” death is made religiously viable with the very use of technological apparatus and scientific rhetoric that stand at the heart of the scientific ethos.

Compassionate care during withdrawal of treatment: A secondary analysis of ICU nurses' experiences

BACKGROUND:

Withdrawal of treatment is a common practice in intensive care units when treatment is considered futile. Compassion is an important aspect of care; however, it has not been explored much within the context of treatment withdrawal in intensive care units.

OBJECTIVES:

The aim was to examine how concepts of compassion are framed, utilised and communicated by intensive care nurses in the context of treatment withdrawal.

DESIGN:

The study employed a qualitative approach conducting secondary analysis of an original data set. In the primary study, 13 nurses were recruited from three intensive care units within a large hospital in United Kingdom. Deductive framework analysis was used to analyse the data in relation to compassionate care.

ETHICAL CONSIDERATIONS:

The primary study was approved by the local Research Ethics Committee and the hospital's Research and Development services.

FINDINGS:

Compassionate care was mostly directed to the patient's family and was demonstrated through care and emotional support to the family. It was predominantly expressed through attempts to maintain the patient's dignity by controlling symptoms, maintaining patient cleanliness and removing technical apparatus.

CONCLUSION:

This study's findings provide insight about compassionate care during treatment withdrawal which could help to understand and develop further clinicians' roles. Prioritising the family over the patient raised concerns among nurses, who motivated by compassion, may feel justified in taking measures that are in the interests of the family rather than the patient. Further work is needed to explore the ethics of this.

Cremation in Norway: regulation, changes and challenges

In this article, I explore the development of modern cremation and cremation events in Norway. I focus on the multiple ontologies of cremation events and the relationships between the living mourners and the dead during the gradual transformation of the social person within Christian, secular as well as Hindu traditions in Norway. Within Christian tradition, this is a linear process that I intentionally contrast with the predominantly cyclical process within the Hindu tradition. I illustrate how various cosmological, eschatological, soteriological, economical, environmental, as well as socio-political factors regulate and shape the form and content of cremation events and disposal in Norway.

Organ donation as transition work: Policy discourse and clinical practice in The Netherlands

An increasing number of patients become eligible for organ transplants. In the Netherlands, at the level of policy discourse, growing waiting lists are often referred to as a persistent “shortage” of organs, producing a “public health crisis.” In this way, organ donation is presented as an ethical, social, and medical necessity. Likewise, policy discourse offers a range of seemingly unambiguous solutions: improving logistical infrastructure at the level of hospitals, developing organizational and legal protocols, as well as public information campaigns. Instead of taking these problem and solution definitions as given, we critically examine the relationship between policy discourse and clinical practice. Based on a historical review, first, we trace the key moments of transformation where organ donation became naturalized in Dutch policy discourse, particularly in its altruistic connotation. Second, based on in-depth interviews with medical professionals, we show how those involved in organ donation continue to struggle with the controversial nature of their clinical practice. More specifically, we highlight their use of different forms of knowledge that underlie clinicians’ “transition work”: from losing a patient to “gaining” a donor.

Music during after-death care: a focus group study

BACKGROUND

The intensive care unit (ICU) is not only a place to recover from injuries incurred during accidents and from serious illness. For many patients, it is also a place where they might die. Nursing care does not stop when a patient dies; rather, it continues with the care of the deceased and with family support. The aims of this study were (1) to explore the experiences and attitudes of nurses towards the use of ambient music in the ICU during after-death care and (2) to describe the feedback nurses received from relatives when music was used during the viewing.

METHOD

A qualitative design employing focus group interviews was used. Three focus group interviews with 15 nurses were conducted. All the interviews were audiotaped, transcribed verbatim and analysed using qualitative content analysis.

FINDINGS

Six main categories of attitudes emerged from the analysis: (1) different attitudes among nurses towards the use of music; (2) music affects the atmosphere; (3) music affects emotions; (4) use of music was situational; (5) special choice of music and (6) positive feedback from the bereaved.

CONCLUSION

This study demonstrates that music might be helpful for nurses during after-death care as well as for the care of the relatives.

RELEVANCE TO CLINICAL PRACTICE

Including ambient music in an after-death care programme can help nurses show respect for the deceased as the body is being prepared. Music played during the viewing may be a way of helping relatives in their time of grieving. It may ease the situation by making that event special and memorable. However, standardizing this intervention does not seem appropriate. Rather, the individual nurse and the family must decide whether music is to be used in a particular situation.
