The nurse needs to be aware of possible causes of nausea and vomiting such as hypercalcaemia, disseminated carcinoma, renal failure and vestibular stimulation particularly in patients with primary brain tumours or secondary cancer deposits. Constipation and radiotherapy, urinary tract infection and chemotherapy- the causes are many and varied. Hogan (1990) suggests that an understanding of the various pharmacological and non-pharmacological interventions is the foundation of symptom control but that the nurse’s commitment to alleviate the symptoms is the most important variable. Simple techniques like minimising cooking smells, presenting small meals and ensuring offensive odours such as foul linen bags from the vicinity can all be employed in conjunction with pharmacological methods to minimise nausea and vomiting. Successful management requires an understanding of the cause of the symptoms.Other symptoms that may prove troublesome for the terminally ill patient include oral thrush and stomatitis, diarrhoea, lethargy and insomnia. Dyspnoea can be the cause of great distress and the expert nurse will be aware of the need to employ techniques to minimise discomfort. These may include reducing exertion by the patient, positioning them to allow maximum comfort when breathing and improving air circulation by use of fans or open windows. Humidification by methods such as nebulised saline may also be helpful. Pharmacological methods such as morphine either orally, subcutaneously or as a nebulised solution have also been found to decrease the perception of breathlessness (Chater, 1991) and anxiolitics such as Lorazepam s/l are quite helpful. Reassurance and providing a calm environment are also helpful techniques to employ. Distressed relatives around...
