About
Nausea and vomiting
- Nausea is common due to uraemia and comorbidity or side effect of other drugs.
- Antiemetics for nausea and vomiting that occurs with opioid therapy are usually only needed for the first four or five days.
- Good mouth care (eg, keeping the mouth clean with foam sticks and saline) is needed for those who are unable to drink.
- Removal of stimuli (eg, sights, smells and certain fatty, spicy or salted foods), relaxation, distraction and massage.
- Acupuncture and ginger have been shown to be effective for chemotherapy-induced emesis and anticipatory nausea

Raised intracranial pressure
- Dexamethasone 8 mg od (bd if severe symptoms) for 5 days titrating down according to symptoms/response.
Discuss with Oncologist radiotherapy.
- Consider gastroprotection; steroids alone do not significantly increase risk of GI bleed but do by around a factor of 4 when given with NSAIDs
- Initiate anticonvulsants after first seizure; Levatiracetam 250mg od starting dose is recommended-consider specialist neurological advice
Breathlessness
- This at the stage where time is short and diagnosis such as PE or Pneumonia often not being pursued
- Discuss with patient and those important to patient
- Breathless consider it may be due to pulmonary oedema, acidosis, anxiety or lung disease
- In some cases removing fluid from a large pleural effusion may give some temporary relief but weigh up risks.
- In others fluid restriction will help pulmonary oedema.
- When all options unreasonable manage symptoms with opiates
- A fan blowing air may help. Oxygen may occasionally be useful if hypoxic
- Anxiety component so consider Diazepam and Midazolam
- Bronchodilators e.g. salbutamol may help wheeze
- Prednisolone 60 mg OD for SVC or tumour obstruction +/- stenting
- Anticoagulation where felt to be in best interest if suspected PE
- Suffering may be less if Opiates started rather than specific causes explored

Hepatic distension syndrome (liver capsule pain):
- First line: follow WHO analgesic ladder; usually responds well to opioids.
- If pain uncontrolled,consider Dexamethasone under specialist advice.
Palliation : Respiratory secretions
- This at the stage where time is short and diagnosis such as PE or Pneumonia often not being pursued
- Discuss with patient and those important to patient
