En
Management of symptoms

GENERAL CONSIDERATIONS

Recommendations

  1. To guide decisions on symptom management, assess the main symptoms systematically, to reduce the risk of any being underestimated, and quantify their severity using scales that enable us to assess the results of any measures taken.
  2. Thoroughly review treatment given in the last stage of a patient´s life and adapt it to therapeutic objectives focused on well-being and symptom control.
  3. Stop all treatments that are futile, that is, that do not provide any benefit in the patient´s current condition, discuss the risks and benefits of any medication proposed, and explain that the withdrawal of a medication is due its futility given the patient’s current condition.
  4. Leave clear instructions regarding the treatment in writing, indicating the baseline dosages and alternatives for use at times of crisis.

 

Rationale

The GDG has issued recommendations on good clinical practice focused on the general principles of prescribing in palliative care. Further, a list of key clinical considerations has been drawn up, related to the implementation of the recommendations.

Question

Which medications are most effective for alleviating pain in the last days of life?

Recommendations

  1. Within an overall palliative care approach, encourage appropriate assessment and management of pain in order that patients reach the last days of life with their pain under control, with medication continued and adjusted appropriately. Anticipate patients’ potential needs for analgesia and prescribe medication to provide appropriate pain control in advance, enabling families/close friends and/or the healthcare team to manage the situation as and when necessary.
  2. Do not routinely prescribe analgesic drugs because, though pain is a very common symptom, it is not experienced by everyone in the last days of life.
  3. Consider non-pharmacological ways of managing pain in the last days of life together with pharmacological treatments.
  4. Once reversible causes have been ruled out, the pharmacological treatment of choice for moderate-to-severe pain is opioids. If patients experience mild pain, use “first step” drugs, except when a poor response is expected or there are problems with the route of administration, in which case, consider low-dose opioids.
  5. If opioids are given, fast-acting morphine (oral or parenteral) is the medication of choice in the last days of life.
  6. Do not reduce or stop opioids abruptly, as both such a reduction or withdrawal and poorly controlled pain are known risk factors for disorientation and delirium in patients with advanced chronic conditions.
  7. In patients with neuropathic pain, maintain baseline medication as far as possible, although some may need to be discontinued since the oral route is often not an option in the last days of life, and therefore, take this into account in opioid dosing.

 

Rationale

Given the paucity of scientific evidence on the effectiveness of various drugs for managing pain in patients in the last days of life, the GDG has made recommendations based on the general principles of pain control and management in stages before palliative care and its members’ clinical experience. These recommendations seek to encourage appropriate assessment and control of pain in the last days of life, bearing in mind the major impact of pain.

Question

Which medications are most effective for alleviating dyspnoea in the last days of life?

Recommendations

  1. Maintain or start specific treatment if the problem that causes dyspnoea (for example, pulmonary oedema, or pleural effusion) is known and the risk-benefit balance is positive.
  2. Use non-pharmacological strategies first, adding pharmacological treatment as and when necessary, to manage dyspnoea in the last days of life.
  3. In the event that the non-pharmacological measures do not alleviate dyspnoea, offer a trial of oxygen therapy regardless of the hypoxemia severity and maintain the therapy if the patient/family perceives a benefit.
 

  1. If dyspnoea is poorly controlled with the aforementioned measures, add symptomatic treatment with morphine, midazolam, or a combination thereof.

 

Rationale

Three good clinical practice recommendations have been made regarding the indications for pharmacological treatment and starting of non-pharmacological measures. Taking into account the quality of the evidence and the risk-benefit balance, we make a weak recommendation in favour of the use of drugs (opioids, benzodiazepines, or a combination of thereof).

Question

Which drugs are most effective for alleviating nausea and vomiting in the last days of life?

Recommendations

  1. In patients in the last days of life, perform a proportionate assessment of potential causes of nausea and vomiting, which could include:
    • Certain drugs
    • Chemotherapy and/or radiotherapy
    • Psychological factors
    • Biochemical factors, for example, hypercalcemia
    • High intracranial pressure
    • Poor gastrointestinal motility
    • Bowel obstruction.
  2. Consider non-pharmacological measures to treat nausea and vomiting in the last days of life.
  3. In other clinical scenarios, use standard antiemetic medication for palliative care: neuroleptics, antihistamines, prokinetic agents, 5-HT3 receptor antagonists, corticosteroids and benzodiazepines.
 

++++++++

  1. For the treatment of nausea and vomiting in people with bowel obstruction, as well as other pharmacological and non-pharmacological measures, use the following treatments:
    • Hyoscine butylbromide, also known as scopolamine butylbromide, as first-line antisecretory treatment
    • Octreotide if symptoms do not improve within 24 hours after starting treatment with hyoscine butylbromide.

 

Rationale

Two good clinical practice recommendations have been made focusing on assessing the causes of nausea and vomiting and starting of non-pharmacological measures. In the event of bowel obstruction, a weak recommendation has been made in favour of the use of certain medications, taking into account the quality of the evidence; for other clinical scenarios, one good clinical practice recommendation has been made, due to the scarcity of end-of-life research addressing this question.

Question

Which drugs are most effective for alleviating anxiety, delirium and agitation in the last days of life?

Recommendations

  1. Assess all patients in the last days of life for anxiety and delirium (with or without agitation).
  2. Explore and manage potential causes of anxiety and delirium, for example, pain, urinary retention and faecal impaction, in a proportionate manner, in the context of the last days of life and considering the preferences of patients and their families and close friends.
  3. Use non-pharmacological measures for the prevention and management of anxiety and delirium. Give support and training to the family.
  4. Consider using benzodiazepines for managing anxiety.
  5. Consider using traditional antipsychotic medication, and if there is a poor response, its combination with benzodiazepines, for managing delirium.

 

Rationale

Five good clinical practice recommendations have been made focused on improving assessment and the use of non-pharmacological measures. Given that no studies were found assessing the effectiveness and safety of medications for the treatment of anxiety or delirium in the last days of life, the GDG recommend using the medications most widely employed in clinical practice and for which there is considerable experience of their use at this stage.

Question

Which drugs are most effective for alleviating noisy breathing in the last days of life?

Recommendations

  1. As a person enters the last days of life, be alert to the onset of noisy breathing to consider early initiation of treatment.
  2. Provide information about the causes of noisy breathing and address any concerns, underlining that, although the noise can be distressing, it is unlikely to cause discomfort to the patient due to the low level of consciousness.
  3. Take non-pharmacological measures to alleviate noisy breathing to reduce any potential discomfort in people in the last days of life and their family and friends.
  4. Consider pharmacological treatment of noisy breathing when non-pharmacological measures and communication with the patient and their family prove to be insufficient.

 
  1. Use scopolamine (hyoscine) butylbromide as the first-line treatment, although atropine or scopolamine hydrobromide can be used as alternatives.

 

Rationale

One weak recommendation has been made in favour of the use of drugs for noisy breathing in the last days of life, taking into account the quality of the evidence, which is very low according to the GRADE system, and the risk-benefit balance of the treatments. This recommendation is accompanied by a series of clinical practice recommendations focused on the identification and early management of noisy breathing, improvement of the communication process, and use of non-pharmacological measures.
