Luto nos familiares da pessoa em situação de cuidados paliativos

Enquadramento: O luto é algo complexo e abarca múltiplas dimensões que podem resultar em luto patológico. Objetivos: Determinar a prevalência de luto complicado em familiares de pessoas em situação paliativa; identificar que variáveis sociodemográficas e de contexto do luto interferem no processo de luto complicado; averiguar se há relação entre a funcionalidade familiar, satisfação quanto aos cuidados prestados ao ente querido, a sobrecarga do cuidador e o luto em familiares de pessoas em situação paliativa. Métodos: Estudo quantitativo, transversal, descritivo e correlacional, realizado numa amostra de 75 familiares de doentes em situação paliativa. Utilizou-se um Questionário Sociodemográfico; Escala de Apgar Familiar (Agostinho & Rebelo, 1988), Escala do Contexto do Luto (Cunha, 2014), Escala de Avaliação da Satisfação dos Familiares dos Doentes em Cuidados Paliativos - Escala FAMCARE (Almeida, 2012), Escala de Sobrecarga do Cuidador (Sequeira, 2010) e o Inventory of Complicated Grief (ICG) (Frade & Rocha, 2008). Resultados: Dos 75 participantes, apenas 24 (35.2%) que se encontravam pelo menos há 6 meses enlutados obtiveram uma pontuação superior a 30 no ICG, tradutora de vivência de luto complicado. Destes, 58.3% eram mulheres e 41.7% homens; na faixa etária =<49 anos (37.5%); com companheiro(a) (54.2%); 70.8% revelam funcionalidade familiar; 62.5% dos participantes perdeu um familiar direto, cujo falecimento ocorreu em 71.4% dos casos no domicílio; 83.3% dos familiares revelam sobrecarga com os cuidados; 29.2% revelam-se insatisfeitos com os cuidados prestados ao seu familiar. Conclusão: Os resultados revelam a necessidade de identificação dos fatores de risco no luto, de modo a mobilizarem-se os recursos para a promoção da vivência saudável do luto.

Factors influencing the experience of the terminal phase and the grieving process: the primary caregiver’s perspective

Theoretical framework: The experience of the terminal phase and death by patients and caregivers is influenced by multiple factors. This study aimed at understanding this experience from the primary caregiver’s perspective. Objectives: To describe the factors that, from the primary caregiver’s perspective, influenced the experience of disease in the terminal phase and mourning for the death of a close person; To understand the influence of nurses’ conduct on the experience of disease in the terminal phase and mourning for the death of a close person from the primary caregiver’s perspective. Methodology: Qualitative descriptive exploratory study. Results: The following factors were valued: To Assume the Caregiver’s Role, To allow for the end-of-life/terminal phase to take place at home/near the family and Process of Care. Regarding the nurses’ conduct, the knowledge, communication and relationship established by nurses were also valued. Conclusion: In addition to expanding the implementation of specific palliative care teams, the acquisition and development of basic skills in this area by most health care professionals is essential.

The Art of Enduring Contradictory Goals: Challenges in the Institutional Co‐construction of a ‘Good Death’

This paper focuses on the normative notion of ‘good death’, its practical relevance as a frame of reference for ‘death work’ procedures in institutional elder care in Switzerland and the ways in which it may be challenged within migrant ‘dying trajectories’. In contemporary palliative care, the concept of ‘good death’ focuses on the ideal of an autonomous dying person, cared for under a specialised biomedical authority. Transferred to the nursing home context, characterised by long-term basic care for the very old under conditions of scarce resources, the notion of ‘good death’ is broken down into ready-to-use, pragmatic elements of daily routines. At the same time, nursing homes are increasingly confronted with socially and culturally diversified populations. Based on ethnographic findings, we give insight into current practices of institutional ‘death work’ and tensions arising between contradicting notions of a ‘good death’, by referring to decision-making, life-prolonging measures, notions on food/feeding and the administration of sedative painkillers.

Morphine-3-glucuronide's neuro-excitatory effects are mediated via indirect activation of N-methyl-D-aspartic acid receptors: Mechanistic studies in embryonic cultured hippocampal neurones

Indirect evidence indicates that morphine-3-glucuronide (M3G) may contribute significantly to the neuro-excitatory side effects (myoclonus and allodynia) of large-dose systemic morphine. To gain insight into the mechanism underlying M3G' s excitatory behaviors, We used fluo-3 fluorescence digital imaging techniques to assess the acute effects of M3G (5-500 muM) on the cytosolic calcium concentration ([Ca2+](CYT)) in cultured embryonic hippocampal neurones. Acute (3 min) exposure of neurones to M3G evoked [Ca2+](CYT) transients that were typically either (a) transient oscillatory responses characterized by a rapid increase in [Ca2+](CYT) oscillation amplitude that was sustained for at least similar to30 s or (b) a sustained increase in [Ca2+](CYT) that slowly recovered to baseline. Naloxone-pretreatment decreased the proportion of M3G-responsive neurones by 10%-25%, implicating a predominantly non-opioidergic mechanism. Although the naloxone-insensitive M3G-induced increases in [Ca2+](CYT) were completely blocked by N-methyl-D-aspartic acid (NMDA) antagonists and 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) (alphaamino-3-hydroxy-5-methyl-4-isoxazolepropiordc acid/ kainate antagonist), CNQX did not block the large increase in [Ca2+](CYT) evoked by NMDA (as expected), confirming that N13G indirectly activates the NMDA receptor. Additionally, tetrodotoxin (Na+ channel blocker), baclofen (gamma-aminobutyric acid, agonist), MVIIC (P/Q-type calcium channel blocker), and nifedipine (L-type calcium channel blocker) all abolished M3G-induced increases in [Ca2+](CYT), suggesting that M3G may produce its neuro-excitatory effects by modulating neurotransmitter release. However, additional characterization is required.

Use of complementary and alternative medicine and quality of life: changes at the end of life

The purpose of this study was to compare the physical, psychological and social dimensions associated with quality-of-life outcomes over the last year of life, between advanced cancer users and nonusers of complementary and alternative medicine. One hundred and eleven patients were identified through Queensland Cancer Registry records, and followed up every four to six weeks until close to death using standardized protocols. Outcome measures were symptom burden, psychological distress, subjective wellbeing, satisfaction with conventional medicine and need for control over treatment decisions. At the initial interview, 36 (32%) participants had used complementary/ alternative medicine the previous week; mainly vitamins, minerals and tonics and herbal remedies. Among all participants, 53 (48%) used at least one form of complementary/ alternative medicine over the study period. Only six (11%) visited alternative practitioners on a regular basis. Overall, complementary/ alternative medicine users reported higher levels of anxiety and pain, less satisfaction with conventional medicine and lower need for control over treatment decisions compared with nonusers. These differences tend to change as death approaches. A more rigorous assessment of complementary/ alternative medicine use, psychological distress, pain and subjective wellbeing among patients with advanced cancer is needed in the clinical setting.

Factors associated with the wish to hasten death: a study of patients with terminal illness

Background. There is considerable debate regarding the clinical issues surrounding the wish to hasten death (WTHD) in the terminally ill. The clinical factors contributing to the WTHD need further investigation among the terminally ill in order to enhance understanding of the clinical assessment and treatment needs that underlie this problem. A more detailed understanding may assist with the development of appropriate therapeutic interventions. Method. A sample of terminally ill cancer patients (N=256) recruited from an in-patient hospice unit, home palliative care service and a general hospital palliative care consulting service from Brisbane Australia between 1998-2001 completed a questionnaire assessing psychological (depression and anxiety), social (family relationship, social support, level of burden on others) and the impact of physical symptoms. The association between these factors and the WTHD was investigated. Results. A high WTHD was reported by 14% of patients. A discriminant function analysis revealed that the following variables were associated with a high WTHD (P

Doctors and their patients: A context for understanding the wish to hasten death

There is a paucity of research that has directly examined the role of the health professional in dealing with a terminally ill patient's wish to hasten death (WTHD) and the implications of this for the support and services needed in the care for a dying patient. Themes to emerge from a qualitative analysis of interviews conducted on doctors (n = 24) involved in the treatment and care of terminally ill patients were (i) the doctors' experiences in caring for their patients (including themes of emotional demands/expectations, the duration of illness, and the availability of palliative care services); (ii) the doctors' perception of the care provided to their respective patients (comprising themes concerning satisfaction with the care for physical symptoms, for emotional symptoms, or overall care); (iii) the doctors' attitudes to euthanasia and (iv) the doctors' perception of their patients' views/beliefs 'regarding euthanasia and hastened death. When responses were categorised according to the patients' level of a WTHD, the theme concerning the prolonged nature of the patients' illnesses was prominent in the doctor group who had patients with the highest WTHD, whereas there was only a minority of responses concerning support from palliative care services and satisfaction with the level of emotional care in this group. This exploratory study presents a set of descriptive findings identifying themes among a small group of doctors who have been involved in the care of terminally ill cancer patients, to investigate factors that may be associated with the WTHD among these patients. The pattern of findings suggest that research investigating the doctor-patient interaction in this setting may add to our understanding of the problems (for patients and their doctors) that underpins the wish to hasten death in the terminally ill.

Medicalizing meaning: demoralization syndrome and the desire to die

Objective: To critically analyse the proposed new psychiatric condition, demoralization syndrome, and the implications drawn by its proponents for the clinical-ethical status of requests by terminally ill patients for assistance to die. Method: The diagnostic features of demoralization syndrome, a proposed new psychiatric disorder, recognizable particularly in palliative care settings, are summarized. The consequences of proposed therapeutic interventions are described, one of which is relief of the desperation which motivates some demoralized patients to consider ending their lives and to seek assistance in dying. The connections between the proposed condition and the desire to die are analysed in the context of the continuing tensions surrounding the ontological status and sociopolitical implications of psychiatric categories and the pervasive medicalization of modern life. Results: The analysis suggests that by medicalizing existential cognitions at the end of life, the proposed diagnostic category also normalizes a particular moral view concerning assistance in dying. Conclusions: While further research into the issues described in this provisional syndrome may benefit some patients, the categorization of demoralization as a medical diagnosis is a questionable extension of psychiatry's influence, which could serve particular social, political and cultural views concerning the end of life.

Association between clinician factors and a patient's wish to hasten death: Terminally ill cancer patients and their doctors

This study investigated the clinical factors associated with a wish to hasten death among patients with advanced cancer receiving palliative care, with a focus on the role of clinician-related factors. Patients were grouped into high- and low-scoring groups on the basis of their wish to hasten death; doctor-patient pairs were formed. Questionnaire data collected from patients and their treating doctors were subjected to multivariate analysis. Significant predictors of a high wish to hasten death in terminally ill patients from among treating clinicians included the clinician's perception of the patient's lower optimism and greater emotional suffering, the patient indicating a wish to hasten death, the doctor willing to assist the patient in hastening death (if requested and legal), and the doctor reporting less training in psychotherapy. When these variables were combined with patient factors identified in a previous study, the model significantly predicted a wish to hasten death with the following variables patient factors: a higher perceived burden on others, higher depressive symptom scores, and lower family cohesion; physician factors: the doctor willing to assist the patient in hastening death (if requested and legal), the doctor's perception of lower levels of optimism and greater emotional distress in the patient, and the doctor having less training in psychotherapy; and the setting of care: recent admission to a hospice. The findings support the multifactorial influences on the wish to hasten death and suggest that the role of the clinician is a vital context within which the wish to hasten death should be considered.

Physicians' attitudes towards end-of-life decisions: a comparison between seven countries

In the context of an European collaborative research project (EURELD), a study on attitudes towards medical end-of-life decisions was conducted among physicians in Belgium, Denmark, Italy, the Netherlands, Sweden and Switzerland. Australia also joined the consortium. A written questionnaire with structured questions was sent to practising physicians from specialties frequently involved in the care of dying patients. 10,139 questionnaires were studied. Response rate was equal to or larger than 50% in all countries except Italy (39%). Apart from general agreement with respect to the alleviation of pain and symptoms with possible life-shortening effect, there was large variation in support-between and within countries-for medical decision that may result in the hastening of death. A principal component factor analysis found that 58% of the variance of the responses is explained by four factors. 'Country' explained the largest part of the variation of the standardized factor scores. (c) 2004 Elsevier Ltd. All rights reserved.
