Syringe Driver/Pump Usage

The following guidelines acknowledge that subtle changes in clinical practice may occur between hospital, hospice and community practice and endeavour to promote safe and consistent methods of practice, based on collaborative experience around the West Midlands Region.

INDICATIONS FOR STARTING A SYRINGE DRIVER/PUMP

The syringe driver/pump may be indicated in the following situations:

  • persistent nausea or vomiting
  • difficulty swallowing
  • poor alimentary absorption
  • intestinal obstruction
  • profound weakness / cachexia
  • comatose or moribund patient
  • administration of drugs that cannot be given by non-parenteral routes

CARE OF THE SYRINGE DRIVER/PUMP

If doses of drugs need to be changed then change the syringe and the infusion line. It is best not to alter the rate.

Check the syringe driver/pump and infusion regularly for:

  • irritation at the injection site (site reaction), change site or ask advice
  • crystallisation of drug (seek specialist advice)
  • discolouration (seek specialist advice)
  • light flashing (if not check the battery)
  • secure connections or kinked tubing
  • leakage
  • correct volume remaining

CHOICE OF INFUSION SITES

Sites of choice include:

  • anterior chest wall
  • lateral upper arms
  • anterior abdominal wall
  • anterior outer thigh
  • area over scapula (in confused or disorientated patient)

Avoid areas of inflammation, oedema, broken skin, bony prominences, recently irradiated areas, sites of tumour, sites of infection, skin folds or lymphoedema.

SELECTION OF DRUGS

The choice of drug is dictated by the symptom, and the compatibility with other drugs to be delivered. See Compatibility Chart below:

PRESCRIBING FOR THE SYRINGE DRIVER/PUMP

The dose of each drug to be given by infusion over a specified time period (usually 24 hours) should be clearly written.

  • Opioids via the syringe driver/pump will not give better analgesia than orally unless there is a problem with absorption or administration of the drug
  • Long term use is rarely indicated but if required a syringe driver/pump may be maintained as long as is necessary
