Ministry of Health MOH. It is presumed that the incompatibility between midazolam and dexamethasone is due to the alkaline nature of dexamethasone causing an increase in solution pH. Morphine was found to be physically and chemically incompatible with both ketorolac 1. This can be a concern for patients and families if the clinicians or nurses visit is delayed. Once mixed, syringes should be observed for any signs of precipitation or discolouration. The articles included from the abstract stage were read in full and their reference lists searched by JB and AD with any queries regarding a papers eligibility were resolved following a discussion between JB, AD and SM.

Similar documentation is recommended for patients who are receiving care at home. More stability data is required before the use of hour CSCIs can be evaluated for use within clinical practice. Compatibility of medicines for syringe driver infusions commonly prescribed in general practice Adapted from Palliative Care Handbook The ability to gain effective symptom control due to steady plasma drug concentrations without peaks and troughs Allows management of multiple symptoms through the use of combinations of medicines given via a single route The single route of administration minimises the need for repeated injections or multiple oral medicines Subcutaneous administration of medicines is more comfortable for the patient than intramuscular injections particularly if the patient is cachexic and is simpler and less invasive than medicines given intravenously The ability for patients who are still mobile to remain so, and once set up enables more independence.
However, the ability to deliver prescribed medication by a CSCI over 48 hours may have numerous benefits in both patient care and health service resource utilisation. This is usually a sufficient volume for a hour CSCI containing most multiple drug combinations.
Register to use all the features of this website, including selecting clinical areas of interest, taking part in quizzes and much more. The first formulation was comprised of morphine tartrate mg, dexamethasone 8mg, droperidol 2mg, hyoscine- N -butylbromide 20mg and midazolam 8mg. Plastic cannulae are recommended, although metal butterfly needles can be used. Sterile water is compatible with most medicines with some exceptions, e.
However, the final concentrations of drugs in the admixtures were equivalent to that expected in most CSCI combinations in the UK. 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. Physical compatibility and in vivo evaluation of drug mixtures for subcutaneous infusion to cancer patients in palliative care.
BPJ When and how to use a syringe driver in palliative care
The ability to administer CSCIs to patients over extended time periods may benefit patients through providing greater independence, autonomy and improved quality of life as a result of receiving a reduced number morlhine interventions such as syringe changes. This item is 6 years and 1 month old; some content may no longer be current.
Our Commitment to you for end of life care: Journal of Pharmacy and Pharmacology. Wilson et al[ 15 ] investigated the compatibility and stability of fentanyl micrograms, micrograms or micrograms in combination with midazolam 5mg, 7. This left 21 papers which reported chemical stability and compatibility data for multiple-drug containing syringes over a hour or greater time period Fig 1.
However, the administration device and syringe in situ may still need to be checked e.
The clinical performance of the admixture was retrospectively assessed in 21 terminal oncology patients. Most symptoms can syrlnge controlled with a continuous subcutaneous infusion 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.
Medication use during end-of-life care in a palliative care centre. The most commonly included opioid was morphine, with 7 combinations including the sulphate salt, 3 including the hydrochloride salt and 1 including morphine tartrate.
When and how to use a syringe driver in palliative care
Neither time nor temperature affected the stability of fentanyl at any concentration, but midazolam appeared to be subject to time-dependent degradation, especially at higher temperatures. HPLC-DAD methods for studying the stability of solutions containing hydromorphone, morphhine, haloperidol, midazolam, famotidine, metoclopramide, dimenhydrinate, and scopolamine. A total of 24 drugs were included in the 21 studies, involving 32 different combinations.
The Australian Journal of Hospital Pharmacy. Controlled drugs that are no longer required for a patient can be returned to the pharmacy or general practice for safe disposal. Negro et al; ; Spain [ 29 ]. It may be possible to revert back to the use of oral medicines once control of the nausea and vomiting is achieved. All studies, bar one Destro et al [ 33 ]as ajd minimum used a mean of replicate results morpphine standard deviation or better for analysing the chemical compatibility and stability of the drug combination investigated by HPLC.
For example, a patient with severe nausea and vomiting that temporarily prevents the use of oral medicines may need a syringe driver to gain control of symptoms. S1 File Full text assessment form.
Replicate syringes subjected to identical storage and temperature procedures produced no visible crystallisation, but HPLC analysis again indicated a clinically significant decrease in midazolam concentration. Summary table or articles included in this review. Care of the syringe driver once in use The safety aspects of the syringe driver What to halloperidol and where to get advice if the syringe driver is not working properly, or symptoms are not controlled, e.
