Gastro-intestinal pain The pain of bowel colic may be reduced by loperamide hydrochloride. Dyspnoea Breathlessness at rest may be relieved by regular oral morphine in carefully titrated doses. In palliative care, medicines may be prescribed for unapproved indications, be administered by an unapproved route or given in doses not seen in routine day-to-day practice. Although drugs can usually be administered by mouth to control the symptoms of advanced cancer, the parenteral route may sometimes be necessary. When an infusion is due to be changed, a delay of an hour or two should not cause problems if the patient’s symptoms are well controlled.

Choice of diluent The choice of diluent for the infusion solution varies according to local guidelines as there is evidence for and against the two most commonly used diluents – sterile water water for injection and normal saline NaCl 0.

If possible, doses should be given through a side port in the syringe driver cannula line to minimise patient distress. Not all types of medication can be used in a subcutaneous infusion. This is because the Niki T34 syringe driver simplifies administration by detecting the syringe size and volume of medicine, and sets the rate to deliver the infusion over the required time period, e. A corticosteroid, such as dexamethasonemay also be helpful if there is bronchospasm or partial obstruction.

Drug treatment The number of drugs should be as few as possible, for even the taking of medicine may be an effort. Nausea and vomiting Haloperidol and levomepromazine can both be given as a subcutaneous infusion but sedation can limit the dose of levomepromazine.

Pain management in palliative care is focused on achieving control of pain by administering the right drug in the right dose at the right time. The first syringe of a new prescription will lose some of the solution when the line is primed, therefore the infusion will not run for a full 24 hours.

Lung cancer in New Zealand News and updates: With guidance and support from the local hospice or district nursing services, General Practitioners can arrange a syringe driver infusion for a patient in their home or in a residential care facility, prescribe and monitor the appropriate mix of medicines and manage breakthrough symptoms.

A regular maintenance dose should also be considered, given twice daily either by mouth or by subcutaneous injection; alternatively use a continuous infusion device. If non-opioid analgesics alone are not sufficient, then an opioid analgesic alone or in combination with a non-opioid analgesic at an adequate dosage, may be helpful in the control of moderate pain.

Dexamethasonemorhine care is needed to avoid precipitation of dexamethasone when preparing it. Increasing the number of medicines in the solution increases the risk of problems with the combinations.

Syringe drivers are often required to provide medicines for symptom management in patients who are terminally ill.

When more than one medicine is used in an infusion solution there is a risk that they may not be compatible, either chemically or physically. Insomnia Patients with advanced cancer may not sleep because of discomfort, cramps, night sweats, joint stiffness, or fear.

As a general guide, plastic cannulae can stay in place for up to a week or more, whereas metal cannulae remain viable for approximately 72 hours.

In palliative care, medicines may be prescribed mmorphine unapproved indications, be administered by an unapproved route or given in doses not seen in routine day-to-day practice. Diazepam may be helpful for dyspnoea associated with anxiety. The equivalent parenteral dose of morphine subcutaneous, intramuscular, or intravenous is about half of the oral dose.

Also consider other methods to relieve a patient’s distress – sometimes taking the time to sit and listen can be as effective as administering a medicine. Breakthrough pain can be treated with additional subcutaneous doses of the opioid being used usually morphine.

If the patient is already receiving an opioid, oxycodone hydrochloride should be started at a dose equivalent to the current analgesic see below.

Thereafter, the dose should be adjusted with careful assessment of the pain, and the use of adjuvant analgesics should also be considered.

This should occur at least every four hours when patients are in a hospice or residential aged care facility. In a palliative care setting, subcutaneous administration of medicines given via a syringe driver is useful for managing symptoms such as pain, nausea, anxiety and restlessness.

Morphine equivalences for transdermal opioid preparations have been approximated to allow comparison with available preparations of oral morphine.
