Syringe pumps are a vital tool for administering medicine, especially in palliative care. However, nurses must have training before using them to ensure patient safety. Syringe pumps offer an alternative route for delivering medicine when the oral route cannot be used. This is particularly important for patients receiving palliative care, for whom a continuous infusion of medication can improve symptom control.

This article explains how to administer drugs safely using these devices. Nursing Times ; ; Syringe pumps are used as part of palliative care to administer medicines subcutaneously to patients who are unable to manage or tolerate oral medication. Ambulatory syringe pumps are portable battery-operated devices for delivering medication by continuous subcutaneous infusion CSCI over a given time period usually 24 hours. They are useful when small volumes of drugs need to be infused at a slow rate Dougherty and Lister,and their compact design enables patients to move around and maintain independence Costello et al, The pumps are simple to operate, but training is essential.

Patients, carers and health professionals often wrongly associated syringe pumps with imminent death Graham and Clarke,but the devices may be used at any time in the care pathway to control symptoms where drugs cannot be administered orally, such as in patients with intractable nausea and vomiting Costello, ; Dickman et al, - Box 1 lists indications for their use. It is therefore important when starting a pump to offer patients and their families reassurance and explain the need for the syringe pump Costello, Continuous subcutaneous infusion maintains a constant serum level of medicines Barnes et al,which achieves better symptom control than intermittent dosing.

It also reduces the need to use less popular routes of administration such as rectal or intravenous Morgan and Evans, Box 2 lists the advantages and disadvantages of CSCI. Box 1. Indications for using a syringe pump. Several models of syringe pump are available. Although the flow rate in both devices is determined by how far the syringe moves in millimetres mmthere are critical differences between the two. As a result, the National Patient Safety Agency published a rapid response report advising all healthcare organisations using ambulatory syringe pumps to change to devices with the following features:.

These also offer all the safety features expected from current infusion pumps. All staff must receive training before using a syringe pump, and be familiar with local policies and procedures. Manufacturers recommend the size of syringe that should be used with their devices. Pumps are calibrated in ml per hour, and it is important to establish what final volume is required in the syringe, then choose a syringe size.There are many different types of infusion pumps, which are used for a variety of purposes and in a variety of environments.

Infusion pumps may be capable of delivering fluids in large or small amounts, and may be used to deliver nutrients or medications — such as insulin or other hormones, antibiotics, chemotherapy drugs, and pain relievers. Others, called ambulatory infusion pumps, are designed to be portable or wearable. Infusion pumps may be powered electrically or mechanically. Different pumps operate in different ways. For example:. What Is an Infusion Pump? A number of commonly used infusion pumps are designed for specialized purposes.

Patient-controlled analgesia PCA pump - A pump used to deliver pain medication, which is equipped with a feature that allows patients to self-administer a controlled amount of medication, as needed.

Insulin pump - A pump typically used to deliver insulin to patients with diabetes.

In a multi-channel pump, fluids can be delivered from multiple reservoirs at multiple rates. A " smart pump " is equipped with safety features, such as user-alerts that activate when there is a risk of an adverse drug interaction, or when the user sets the pump's parameters outside of specified safety limits.A syringe driver is a small battery operated pump designed to deliver medication sub cutaneously just under the skin over a 24 hour period.

The pump holds a syringe containing medication and this is connected to the patient via a small needle and a line. The syringe driver pump is able to deliver a combination of medications and does so continuously without any inconvenience to the patient. Syringe drivers have many applications.

There is a common misconception that they are the last resort and that using one means that you are close to passing away. This is of course untrue and some patients use the drivers intermittently when their symptoms present. Remember: Not everyone who is dying needs a syringe driver and not everyone with a syringe driver is dying. Some disadvantages include:.

Syringe Driver Uses: Advantages and Disadvantages. What is a syringe driver? A continuous infusion avoids peaks and troughs by maintaining plasma drug concentrations. Simply put, this means that pain medication is not stronger when first taken and then wears off so that the patient experiences pain again The patient is unable to swallow oral medication either because they are too unwell or because they have swallowing problems dysphagia Nausea and vomiting means that the medication cannot be taken orally What are the advantages to using a syringe driver?

There are several advantages to Continuous sub cutaneous infusions CSCI : Control of multiple symptoms Maintaining a constant level of medication, no peaks and troughs Avoids the need for hourly injections and invasive treatment Patients can remain mobile and independent with a driver in place Ideal for people who cannot take oral medications Are there any disadvantages to using a syringe driver?

Some disadvantages include: The device uses a 9V battery and currently these only last a few days in the driver, so users will need to maintain a good level of stock Inflammation and infection can occur at the needle site, although generally they are tolerated well.

There are two main types of products: infusion pumps and withdrawal pumps. Infusion pumps are used to administer relatively small amounts of fluids at high, but controlled pressures.

Withdrawal pumps are used to remove fluid samples automatically, typically in medical or pharmaceutical applications. Specifications for both types of syringe pumps include minimum and maximum discharge flow, syringe size, number of pumps per assembly, minimum and maximum step rate, accuracy, reproducibility, physical dimensions and weight.

Power sources, applications, features, media, and certifications are additional considerations. There are many different power sources for syringe pumps. Manual pumps are designed to be driven by hand or foot power. Pneumatic pumps use a compressed air source. Pump-only mechanisms and solar-powered products are also available. Electrically-powered syringe pumps use either direct current DC or alternating current AC waveforms.

DC pumps typically operate with 6, 12, 24, or 32 VDC.

AC pumps use single-phase or three-phase power, depending on the requirements of the application. Single-phase syringe pumps operate with,or VAC. Syringe pumps differ in terms of applications and features. General-purpose products are not designed for a specific industry. Specialized pumps are rated for agricultural, cryogenic, dairy, food and beverage processing, maritime, medical, pharmaceutical, or semiconductor manufacturing applications. In terms of features, some syringe pumps are explosion proof, corrosion resistant, hygienic, portable, or run-dry capable.

Others include a control panel, battery backup, power cord, pressure gauge, strainer or filter. Washdown duty pumps are designed to operate in wet environments such as food processing plants and dairies.

Sanitary pumps meet guidelines established by regulatory agencies such as the U. Suppliers of syringe pumps specify the media which pumps can handle and the certifications and approvals that products bear.

Syringe pump media include acids, chemicals, coolants, combustible fluids, corrosive agents, gasoline or diesel fuel, non-liquid gas or air, ground water, hazardous materials, high viscosity fluids, liquid metal, oils, potable water, salt water, adhesives, and high temperature media.

What should I do if the syringe pump stops working?

What should I do if the syringe pump is in place when the patient dies? Useful resources. Key points. This film is for people who want to learn more about syringe drivers and when they might be used. It's been developed for patients and their families, but may also be useful for health and social care professionals. A syringe pump is a small, battery-powered pump that delivers medication subcutaneously under the skin at a constant rate throughout the day and night.

A syringe pump can also be used over a shorter period of time while the patient needs a specific medicine. There are several reasons why a syringe pump might be a good way to give someone their medicines:. Syringe pumps are often used in the last few weeks and days of life but they can be useful for managing symptoms at any stage of illness.

For example, someone might have antiemetics anti-sickness medicines in a syringe pump to manage nausea and vomiting caused by chemotherapy. Medicines used in syringe pumps are most often those used to treat pain, nausea and vomiting, agitation, secretions and seizures.

Syringe pumps will be set up by a specialist nurse, district nurse or GP. Syringe pumps for palliative care are programmed to deliver the medicines over a hour period, so a new syringe of medicines is usually set up once per day. In these cases, patients will have more than one syringe pump so they can get all their medicines safely.

Syringe pumps are often placed in a clear plastic, locked box. This is a common worry that many patients, friends and family members have. Painkillers and other medicines are safe and effective when prescribed appropriately and administered correctly.

Often they are set up at a time when the patient is rapidly deteriorating and the syringe pump is the best option to manage their symptoms. Listen to their concerns and reassure them that the syringe pump is a safe and effective way to manage their symptoms. You may find it helpful to share our information about syringe pumps with patients and their family or friends. They will also change the cannula regularly.

In the meantime, there are certain things you can do:. They can give you advice on what to do before they arrive. It might be that the battery needs replacing.A syringe driver or syringe pump is a small infusion pump some include infuse and withdraw capabilityused to gradually administer small amounts of fluid with or without medication to a patient or for use in chemical and biomedical research.

Good coding practices

Another use of syringe drivers is in palliative careto continuously administer analgesics painkillersantiemetics medication to suppress nausea and vomiting and other drugs. This prevents periods during which medication levels in the blood are too high or too low, and avoids the use of multiple tablets especially in people who have difficulty swallowing.

As the medication is administered subcutaneouslythe area for administration is practically limitless, although edema may interfere with the action of some drugs. Syringe drivers are also useful for delivering IV medications over several minutes.

U.S. Food and Drug Administration

In the case of a medication which should be slowly pushed in over the course of several minutes, this device saves staff time and reduces errors. Syringe pumps are also useful in microfluidic applications, such as microreactor design and testing, and also in chemistry for slow incorporation of a fixed volume of fluid into a solution. In enzyme kinetics syringe drivers can be used to observe rapid kinetics as part of a stopped flow apparatus.

Syringe Pump (Running a Syringe Pump)

Wikimedia Commons. Wikimedia Commons has media related to Syringe drivers.Most of the positive displacement pumps or volumetric pump, move the fluid handled in an enclosed volume. However, syringe pumps are also positive displacement pump with the difference of handle a fixed volume. Here the differences between the classical volumetric pumps and syringe pumps are discussed to help readers to distinguish and select a pump for your application.

Most of the volumetric pumps work by two general mechanisms: a reciprocating or rotary mechanism. Engineers use positive displacement pumps for systems requiring pressurized fluids, especially in the chemical industry. However, you can find these type of pumps in small plants and factories. The injection systems for engines is another classic positive displacement pumps.

Positive pumps under this modality are a conventional piston or plunger pumps. In the Reciprocating pumps, the displacement bodies as a piston container gradually and periodically increase and decrease the working volume as the pumping takes places, in this way, a volume is transported from the inlet to the outlet.

It is essential for this process that working volumes remain isolated through separated elements as check valves; the intrinsic pressure differences control these elements during pumping the case of rotatory mechanics the rotational speed controls the valves. The main advantage of the isolated devices called valves is that the prevention of fluid flowing back to the suction or discharge line; this feature keeps the positive displacement. Their displacement body, e.

Regarding the variable volume displacement, these pumps are the rotating principle; the conventional rotatory pumps are the gear pump, screw pump or peristaltic pumps.

In general terms this pumps moved finite elements, gear pumps do the process driving the liquid between gear teeth, peristaltic pumps does the same process between the rotatory element there is a hose. The mode of displacement varies slightly as the rotatory element moves through different positions, displacement per shaft revolution may not be accurate after hundreds of operational hours. However, for the case of peristaltic pumps; microfluidic characterization with these pumps is not recommended 1.

Syringe pumps are positive displacement pumps with a fixed volume and usually are not part of the previous classification please check What a syringe pump is?

Chemyx syringe pumps allow the most accurate and reliable operation in a wide range of rates. In general terms, all these pumps allow fluid motion. However, the most important features to distinguish is the precision and the rates they can provide. In-plane terms, syringe pumps are more useful pumps for microfluidic applicationshigh-tech development, and research applications. From the previous description, the pumps that allow a similar control is a peristaltic pump which also provides free contamination because the elements never touch the fluid.

Nevertheless, the hose should be clean or sterilize depending on the application. Chemyx syringe pumps offer the higher standard with the Fusion and ; these pumps used micro-step motors, and they can be customized for high pressure and high viscosity application.

Therefore, Chemyx syringe pumps allow the development of microfluidics for the most exciting fields as biochemistry, biotechnology, material synthesis and chemical synthesis among others.
