Anticholinergic medications can eliminate the so-called "death rattle" brought on by the build-up of secretions when the gag reflex is lost or swallowing is difficult. However, it is important to note that results of clinical trials examining various pharmacologic agents for the treatment of death rattle have so far been inconclusive [6]. Despite the lack of clear evidence, pharmacologic therapies continue to be used frequently in clinical practice [3]. Specific drugs used include scopolamine, glycopyrrolate, hyoscyamine, and atropine (Table 2) [2,3,7]. Glycopyrrolate may be preferred because it is less likely to penetrate the central nervous system and with fewer adverse effects than with other antimuscarinic agents, which can worsen delirium [3]. For patients with advanced kidney disease, the dose of glycopyrrolate should be reduced 50% (because evidence indicates that the drug accumulates in renal impairment) and hyoscine butylbromide should not be used (because of a risk of excessive drowsiness or paradoxical agitation) [4]. Some evidence suggests that treatment is more effective when given earlier; however, if the patient is alert, the dryness of the mouth and throat caused by these medications can be distressful. Repositioning the patient to one side or the other or in the semiprone position may reduce the sound. Oropharyngeal suctioning is not only often ineffective but also may disturb the patient or cause further distress for the family. Therefore, it is not recommended.

Terminal delirium occurs before death in 50% to 90% of patients. It is associated with shorter survival and complicates symptom assessment, communication, and decision making. It can be extremely distressing to caregivers and healthcare professionals alike [3]. Safety measures include protecting patients from accidents or self-injury. Reorientation strategies are of little use during the final hours of life. Education and support for families witnessing a loved one's delirium are warranted [3]. There are few randomized controlled trials on the management of terminal delirium. Agents that can be used to manage delirium include haloperidol, which is frequently the first choice for its relatively quick action [3,8]. Other drugs may include olanzapine, chlorpromazine, levomepromazine, and benzodiazepines [3,8]. For terminal delirium associated with agitation, benzodiazepines, including clonazepam, midazolam, diazepam, and lorazepam may be helpful [3,8,9]. Depending on which drug is used, administration may be intravenous, subcutaneous, or rectal, and the dose can be titrated until effective.

Palliative sedation may be considered when an imminently dying patient is experiencing suffering (physical, psychologic, and/or spiritual) that is refractory to the best palliative care efforts. Terminal restlessness and dyspnea have been the most common indications for palliative sedation, and thiopental and midazolam are the typical sedatives used [1,10,11]. For patients who have advanced kidney disease, midazolam is recommended, but the dose should be reduced because more unbound drug becomes available [1,4]. Before beginning palliative sedation, the clinician should consult with a psychiatrist and pastoral services (if appropriate) and talk to the patient, family members, and other members of the healthcare team about the medical, emotional, and ethical issues surrounding the decision [1,2,9,12,13]. Formal informed consent should be obtained from the patient or from the healthcare proxy.

Physician-assisted death, or hastened death, is defined as active euthanasia (direct administration of a lethal agent with a merciful intent) or assisted death (aiding a patient in ending his or her life at the request of the patient) [2]. The following are not considered to be physician-assisted death: carrying out a patient's wishes to refuse treatment, withdrawal of treatment, and the use of high-dose opioids with the intent to relieve pain. The American Medical Association Code of Ethics explicitly states, "Physician-assisted suicide is fundamentally incompatible with the physician's role as healer, would be difficult or impossible to control, and would pose serious societal risks" [14]. Position statements against the use of physician-assisted death have been issued by many other professional organizations, including the National Hospice and Palliative Care Organization and the American Academy of Hospice and Palliative Medicine (AAHPM) [15,16]. The AAHPM states that their position is one of "studied neutrality" [15]. The basis for these declarations is that appropriate hospice care is an effective choice for providing comfort to dying patients.

Families often misinterpret the early signs of terminal delirium as signs of uncontrollable pain. However, if pain has been adequately managed throughout the delivery of palliative care, such pain will not begin during the last hours. As the patient slips in and out of consciousness, family members may become increasingly distressed about not being able to communicate anymore with their loved one. Although it is unknown what a dying patient can hear, other experiences in medicine suggest that awareness may be greater than the ability to respond. Family members should be encouraged to continue talking with their loved one to help them attain a sense of closure.

Despite the best efforts to prepare the family, reactions are unpredictable when death occurs. The clinician should take time to answer questions from family members, including children, and perhaps provide information on the physiologic events associated with death [2]. For family members who were not present during the death, the clinician should describe the event, while reassuring them that the patient died peacefully.
Many experts believe that people can handle grief better if they spend time with a loved one immediately after death. Family members should be allowed to touch, hold, and kiss their loved one as they feel comfortable. The healthcare team should respect the needs of the family to conduct personal, cultural, or religious traditions, rites, and rituals.

Grief counseling for the family and patient should begin when the patient is alive, with a focus on life meaning and the contributions from the patient's family. An understanding of the mediators of the grief response can help physicians and other members of the healthcare team recognize the family members who may be at increased risk for adapting poorly to the loss [20]. These mediators are:
Nature of attachment (how close and/or dependent the individual was with regard to the patient)
Mode of death (the suddenness of the death)
Historical antecedents (how the individual has handled loss in the past)
Personality variables (factors related to age, gender, ability to express feelings)
Social factors (availability of social support, involvement in ethnic and religious groups)
Changes and concurrent stressors (number of other stressors in the individual's life, coping styles)

Satisfactory adaptation to loss depends on "tasks" of mourning [20]. Previous research referred to "stages" of mourning, but the term "task" is now used because the stages were not clear-cut and were not always followed in the same order. The tasks include:
Accepting the reality of the loss
Experiencing the pain of the loss
Adjusting to the environment in which the deceased is missing (external, internal, and spiritual adjustments)
Finding a way to remember the deceased while moving forward with life

Cultural sensitivity consists of promoting trust and mutual respect for cultural differences between providers and patients [23]. In end-of-life care, an understanding of cultural differences in beliefs about grieving is necessary. In Western culture, grieving is expected to be time-limited, and extended grieving can be considered pathologic [24]. However, in other cultures, extended periods of grieving are socially sanctioned.
