Using anti-muscarinic drugs in the management of death rattle: evidence-based guidelines for palliative care

Association between hydration volume and symptoms in terminally ill cancer patients with abdominal malignancies

BACKGROUND

To explore the association between hydration volume and symptoms during the last 3 weeks of life in terminally ill cancer patients.

PATIENTS AND METHODS

This was a multicenter, prospective, observational study of 226 consecutive terminally ill patients with abdominal malignancies. Primary responsible physicians and nurses evaluated the severity of membranous dehydration (dehydration score calculated from three physical findings), peripheral edema (edema score calculated from seven physical findings), ascites and pleural effusion (rated as physically undetectable to symptomatic), bronchial secretion, hyperactive delirium (Memorial Delirium Assessment Scale), communication capacity (Communication Capacity Scale), agitation (Agitation Distress Scale), myoclonus and bedsores.

RESULTS

Patients were classified into two groups: the hydration group (n=59) who received 1 l or more of artificial hydration per day, 1 and 3 weeks before death, and the non-hydration group (n=167). The percentage of patients with deterioration in dehydration score in the final 3 weeks was significantly higher in the non-hydration group than the hydration group (35% versus 14%; P=0.002), while the percentages of patients whose symptom scores for edema, ascites and pleural effusion increased were significantly higher in the hydration group than the non-hydration group (44% versus 29%, P=0.039; 29% versus 8.4%, P <0.001; 15% versus 5.4%, P=0.016; respectively). After controlling for multiple covariates and treatment settings, the association between hydration group and dehydration/ascites score was statistically significant. Subgroup analysis of patients with peritoneal metastases identified statistically significant interaction between hydration group and dehydration/pleural effusion score. There were no significant differences in the degree of bronchial secretion, hyperactive delirium, communication capacity, agitation, myoclonus or bedsores.

CONCLUSIONS

Artificial hydration therapy could alleviate membranous dehydration signs, but could worsen peripheral edema, ascites and pleural effusions. It is suggested that the potential benefits of artificial hydration therapy should be balanced with the risk of worsening fluid retention symptoms. Further clinical studies are strongly needed to identify the effects of artificial hydration therapy on overall patient well-being, and an individualized treatment and close monitoring of dehydration and fluid retention symptoms is strongly recommended.

Control of common, non-pain cancer symptoms

Despite major advances in cancer biology and therapeutics, cancer and its treatment continue to cause devastating suffering. Patients with advanced cancer most often experience multiple physical and psychological symptom concurrently. We review here some of the common non-pain cancer symptoms, focusing on the assessment and treatment of fatigue, anorexia and cachexia, dyspnea, and symptoms common near the end of life.

Concerns of family members of patients receiving palliative sedation therapy

PURPOSE

Symptomatic sedation is often required in terminally ill cancer patients and could cause significant distress to their families. The aim of this study was to gather vivid family descriptions about their experiences in palliative sedation therapy.

METHODS

This report is an additional analysis of a multicenter questionnaire survey. We performed content analysis on 48 statements described by 185 bereaved family members of patients who received palliative sedation therapy.

RESULTS

Family members reported guilt, helplessness, and physical and emotional exhaustion when patients received palliative sedation therapy. They were concerned about whether sedated patients experienced distress, wished to know that the maximum efforts had been made, wished to prepare for patient death, wished to tell important things to patients before sedation, wished to understand patients' suffering, and wanted medical professionals to treat patients with dignity.

CONCLUSIONS

To alleviate family distress, clinicians should understand families' emotional distress, ensure that unconscious patients feel no distress, reassure family members that the symptoms are truly refractory despite maximum efforts for symptom relief, give information and coordinate the situation to enable families to prepare for patient death and to tell important things to patients before sedation, help families to share patients' suffering, and treat patients the same as when they remained conscious.

Incidence and underlying etiologies of bronchial secretion in terminally ill cancer patients: a multicenter, prospective, observational study

Although bronchial secretion is frequently observed in terminally ill cancer patients and can cause significant distress for both patients and family members, the pathophysiology is unclear. The primary aim of this study was to investigate the incidence and underlying etiologies of bronchial secretion. A multicenter, prospective, observational study was conducted on consecutive terminally ill patients with lung or abdominal malignancies. Primary physicians and nurses prospectively evaluated patients' symptoms. Of 310 patients enrolled, bronchial secretions were observed in 41% in the final 3 weeks, and oral/bronchial suctioning, with considerable distress, was required in 9%; bronchial secretions were severe in 4.5% of all patients. Multiple logistic regression analyses revealed that the determinants of the development of bronchial secretion were primary lung cancer, pneumonia, and dysphagia. There were no statistically significant effects of severity of peripheral edema and pleural effusion on development of bronchial secretions and requirement for oral/bronchial suctioning. Etiology-based classification of bronchial secretion is useful to identify the most suitable palliative treatments and to clarify treatment efficacy in each specific pathophysiology.

Novel consent process for research in dying patients unable to give consent

OBJECTIVES

To develop a process of advance consent to enable research to be undertaken in patients in the terminal phase.

DESIGN

Feasibility study of an advance consent process to support a randomised controlled trial of two antimuscarinic drugs (hyoscine hydrobromide and glycopyrronium bromide) in the management of noisy respirations associated with retained secretions ("death rattle").

SETTING

Palliative care wards in a major cancer centre.

PARTICIPANTS

Patients admitted to a palliative care ward who may develop "death rattle" and thus be eligible for randomisation.

MAIN OUTCOME MEASURES

Patient accrual; acceptability of the consent process.

RESULTS

Of the 107 patients approached, 58 patients gave advance consent to participate in the study. Of these, 15 patients developed death rattle and were randomised to receive either hyoscine or glycopyrronium; 16 patients died elsewhere; 15 patients died on the palliative care wards but were not randomised; 12 patients are still alive.

CONCLUSIONS

Initial assessment suggests that this is a workable consent process allowing research to be undertaken in patients who are unable to give consent at the time of randomisation. Patient accrual rates to date are lower than needed to recruit adequate numbers in the time allotted to answer the research question.
