INTRODUCTION. Palliative sedation is a measure of last resort used at the end of life to relieve severe and refractory symptoms. It is performed by the administration of sedative medications in monitored settings and is aimed at inducing a state of decreased awareness or absent awareness (unconsciousness).
(PA-lee-uh-tiv seh-DAY-shun) The use of special drugs called sedatives to relieve extreme suffering by making a patient calm, unaware, or unconscious. This may be done for patients who have symptoms that cannot be controlled with other treatment.
Medications that are used to produce the sedation that relieves the distressing symptom(s) include sedating antipsychotics, intravenous benzodiazepines, and subcutaneous or intravenous barbiturates. A systematic review demonstrated no decrease in survival from the implementation of palliative sedation.
Survival. There are reports that after initiation of palliative sedation, 38% of people died within 24 hours and 96% of people died within one week. Other studies report a survival time of < 3 weeks in 94% of people after starting palliative sedation.
Palliative sedation is the continuous administration of medication to relieve severe, intractable symptoms. Palliative sedation induces a coma-like state when symptoms such as pain, nausea, breathlessness, or delirium cannot be controlled while a patient is conscious. This state is maintained until death occurs.
In most cases with CPST, sedation continues until death. In rare cases, however, patients may be woken up at some point, according to Downar.
The important findings, along with observations of long-time palliative care doctors and nurses, show: Brain activity supports that a dying patient most likely can hear. Even if awareness of sound cannot be communicated due to loss of motor responses, the value of verbal interactions is measurable and positive.
Palliative sedation can be associated with an increased risk of aspiration, respiratory depression, and worsening agitation due to delirium.
Palliative sedation is a measure of last resort used at the end of life to relieve severe and refractory symptoms. It is performed by the administration of sedative medications in monitored settings and is aimed at inducing a state of decreased awareness or absent awareness (unconsciousness).
Palliative sedation is used when traditional opioid-based therapies are either inadequate to control suffering or cause unacceptable adverse effects. Often, PS is used to treat delirium, pain, dyspnea, nausea, or other physical symptoms.
The sedation can also be reversed, so the person is not completely asleep during the dying process. Research has shown that palliative sedation does not shorten life. People die from their disease – not from sedatives.
Sometimes that means a light unconsciousness, in which the patient may still be somewhat aware of the presence of others. On other occasions it might mean a deep unconsciousness, not unlike a coma. In some cases, the palliative sedation is limited; in others it continues until death.
Medicine for pain in palliative care – an appropriate opioid, for example, morphine, diamorphine, oxycodone or alfentanil. Medicine for breathlessness – midazolam or an opioid. Medicine for anxiety – midazolam. Medicine for delirium or agitation – haloperidol, levomepromazine, midazolam or phenobarbital.
Stage 4: Terminal
Terminal care will comprise of extensive physical and medical care within the loved one's own home or hospital setting. During this stage of their palliative care journey, individuals may experience the following physical symptoms: Becoming bedridden. Experiencing severe mobility issues.
“The principle of double effect provides justification in which the process is based on the intended outcome of pain and symptom relief and the proportionality of benefit and harm. The intent of palliative sedation is to relieve suffering in dying patients but not to deliberately hasten death.
“Palliative sedation” was used most frequently, sometimes stated with a synonym, for example, “therapeutic sedation”.
Can patients hear us when they are very asleep? It is possible that patients can hear and feel what is going on around them, even when apparently unconscious, but they might be too sleepy to respond when we speak to them or hold their hand.
Palliative care is specialized medical care that focuses on providing relief from pain and other symptoms of a serious illness. It also can help you cope with side effects from medical treatments. The availability of palliative care does not depend on whether your condition can be cured.
Palliative sedation (PS), the medical act of decreasing a patient's awareness to relieve otherwise intractable suffering, is considered by some commentators to be controversial because of its consequences on residual survival and/or quality of life, and to be inappropriate for treating pure existential suffering.
'Palliation sedation' is a widely used term to describe the intentional administration of sedatives to reduce a dying person's consciousness to relieve intolerable suffering from refractory symptoms. Research studies generally focus on either 'continuous sedation until death' or 'continuous deep sedation'.
Further, nurses provide information and compassionate care to both the patient and the family during the process of palliative sedation. Most nurses view palliative sedation as a positive and sometimes necessary last resort therapy to relieve refractory suffering of dying patients.
Potential side effects of sedation, although there are fewer than with general anesthesia, include headache, nausea, and drowsiness. These side effects usually go away quickly. Because levels of sedation vary, it's important to be monitored during surgery to make sure you don't experience complications.
Patients who receive conscious sedation are usually able to speak and respond to verbal cues throughout the procedure, communicating any discomfort they may experience to the provider. A brief period of amnesia may erase any memory of the procedures. Conscious sedation does not last long, but it may make you drowsy.
“First hunger and then thirst are lost. Speech is lost next, followed by vision. The last senses to go are usually hearing and touch.”
These patients often have evolving processes that threaten the airway and adequate ventilation. Furthermore, intubation, ventilation, and sedative choices directly affect brain perfusion. Therefore, airway, ventilation, and sedation was chosen as an emergency neurological life support protocol.
