Introduction
Of all people who die, only a few (< 10%) die suddenly and unexpectedly. Most people (> 90%) die after a long period of illness, with gradual deterioration until an active dying phase at the end. Care provided during those last hours and days can have profound effects, not just on the patient, but on all who participate. At the very end of life, there is no second chance to get it right.
Most clinicians have little or no formal training in managing the dying process or death. Families usually have even less experience or knowledge about death and dying. Based on media dramatization and vivid imaginations, most people have developed an exaggerated sense of what dying and death are like. However, with appropriate management, it is possible to provide smooth passage and comfort for the patient and all those who watch.
Preparing for the Last Hours of Life
Help families to understand that what they see may be very different from the patient’s experience. If family members and caregivers feel confident, the experience can be a time of final gift giving. If they are left unprepared and unsupported, family members may live with frustration, worry, fear, or guilt that they did something wrong or caused the patient’s death.
it is not possible to predict with precision when death will occur. Although it is possible to give families or professional caregivers a general idea of how long the patient might live, always advise them about the inherent unpredictability of the moment of death.

Loss of ability to swallow
- Dysphagia
- Coughing, choking

Loss of sphincter control
- Incontinence of urine or bowels
- Maceration of skin

Loss of ability to close eyes
- Eyelids not closed
- Whites of eyes showing (with or without pupils visible)
Rare, unexpected events:
- Bursts of energy just before death occurs, the “golden glow”
- Aspiration, asphyxiation
Fatigue and weakness
Cutaneous ischemia
Decreasing appetite and food intake
Whatever the degree of acceptance of these facts, it is important for professionals to help families and caregivers realize that food pushed upon the unwilling patient may cause problems such as aspiration and increased tension. Above all, help them to find alternative ways to nurture the patient so that they can continue to participate and feel valued during the dying process.
Decreasing fluid intake and dehydration
Mucosal and conjunctival care
Cardiac dysfunction and renal failure
Neurologic dysfunction
Communication with the unconscious patient
Encourage families to create an environment that is familiar and pleasant. Surround the patient with the people, children, pets, objects, music, and sounds that he or she would like. Include the patient in everyday conversations. Encourage family members to say the things they need to say. As touch can heighten communication, encourage family members to show affection in ways they are used to. Let them know that it is okay to lie beside the patient in privacy to maintain as much intimacy as they feel comfortable with.
Terminal delirium
Respiratory dysfunction
Although it is true that patients are more likely to receive higher doses of both opioids and sedatives as they get closer to death, there is no evidence that initiation of treatment or increases in dose of opioids or sedatives is associated with precipitation of death. In fact, the evidence suggests the opposite.
Loss of ability to swallow
If excessive fluid accumulates in the back of the throat and upper airways, it can be cleared by repositioning the patient or performing postural drainage. Oropharyngeal suctioning is not recommended. Suctioning is frequently ineffective, as fluids are beyond the reach of the catheter, and may only stimulate an otherwise peaceful patient and distress family members who are watching.
Loss of sphincter control
Pain
Loss of ability to close eyes
When Death Occurs
No matter how well families and professional caregivers are prepared, they may find the time of death to be challenging. Families, including children, and caregivers may have specific questions for health professionals.
Basic information about death may be appropriate (eg, the heart stops beating; breathing stops; pupils become fixed; body color becomes pale and waxen as blood settles; body temperature drops; muscles and sphincters relax, and urine and stool may be released; eyes may remain open; the jaw can fall open; and observers may hear the trickling of fluids internally).
Signs That Death Has Occurred
- The heart stops beating
- Breathing stops
- Pupils become fixed and dilated
- Body color becomes pale and waxen as blood settles
- Body temperature drops
- Muscles and sphincters relax (muscles stiffen 4-6 hours after death as rigor mortis sets in)
- Urine and stool may be released
- Eyes may remain open
- The jaw can fall open
- Observers may hear the trickling of fluids internally, even after death
When an expected death occurs, the focus of care should shift from the patient to the family and those who provided care. Even though the loss has been anticipated for some time, no one will know what it feels like until it actually occurs, and indeed it may take hours to days to weeks or even months for each person to experience the full effect.
Many experts assert that the time spent with the body immediately after death will help people deal with acute grief. Those present, including caregivers, may need the clinician’s permission to spend the time to come to terms with the event and say their good-byes. There is no need to rush, even in the hospital or other care facility. Encourage those who need to touch, hold, and even kiss the person’s body as they feel most comfortable (while maintaining universal body fluid precautions).
Because a visually peaceful and accessible environment may facilitate the acute grieving process, a health professional, usually the nurse, should spend a few moments alone in the room positioning the patient’s body, disconnecting any lines and machinery, removing catheters, and cleaning up any mess, to allow the family closer access to the patient’s body.
Notifying Others of the Death
Telephone Notification
There will be situations in which the people who need to know about the death are not present. In some cases, you may choose to tell someone by telephone that the patient’s condition has “changed,” and wait for them to come to the bedside in order to tell the news. Factors to consider in weighing whether to break the news over the telephone include: whether death was expected, what the anticipated emotional reaction of the person may be, whether the person is alone, whether the person is able to understand, how far away the person is, the availability of transportation for the person, and the time of day (or night). Inevitably, there are times when notification of death by telephone is unavoidable. Use the same plan as you would for breaking bad news. See Communication section.
Summary of Take-Home Lessons
- There is only one chance to get management of the last hours right.
- Patients in the last hours of life usually need skilled care around the clock. The environment must allow family and friends ready access to their loved one in a setting that is conducive to privacy and intimacy.
- Advance preparation and education of professional, family, and volunteer caregivers are essential. They should also be knowledgeable about the potential time course, signs and symptoms of the dying process, and their potential management. The physician or nurse needs to help family members understand that what they see may be very different from what the patient is experiencing.
- The physiologic changes of dying are complex. To control each symptom effectively, clinicians need to have an understanding of its cause, underlying pathophysiology, and the appropriate pharmacology to use.
- When death is imminent, fatigue is an expected part of the dying process and should not be treated medically in most cases.
- Most patients lose their appetite and reduce food intake long before they reach the last hours of their lives. Anorexia may be protective, and the resulting ketosis can lead to a greater sense of well-being and diminish pain.
- Most patients also reduce their fluid intake, or stop drinking entirely, long before they die. Dehydration in the last hours of living does not cause distress and may stimulate endorphin release that adds to the patient’s sense of well-being.
- Moisture should be maintained in mucosal membranes with meticulous oral, lip, nasal, and conjunctival hygiene and lubrication.
- Most patients experience increasing drowsiness and sleep much of the time, eventually becoming unarousable.
- It should be assumed that the unconscious patient hears everything.
- Moaning, groaning, and grimacing accompanying agitation and restlessness are frequently misinterpreted as pain. Terminal delirium may be occurring.
- Diminished hepatic function and renal perfusion may change the pharmacology of chronically administered medications.
- Scopolamine or glycopyrrolate will effectively reduce the production of saliva and other tracheobronchial tree.
- Planning discussions should cover personal, cultural, and religious traditions, rites, and rituals that may dictate how prayers are to be conducted, how a person’s body is to be handled after death, and when and how the body can be moved.
- When an expected death occurs, the focus of care shifts to the family and those who provided care.
