Full description
Peripheral catheters are the most frequently used medical devices in acute care settings, primarily for intravenous medication, fluid, and blood administration.1 However, their use is linked to various complications and risks, such as phlebitis, pain, infiltration, hematoma, occlusion, and more severe issues like bacteremia and sepsis.2 Studies indicate that the failure rate of peripheral catheters ranges between 35% and 50%, often due to dislodgment, infiltration, and other factors.2 These failures can lead to repeated venipunctures, increasing the risk of infection, pain, and potential damage to veins, all of which can impact patient comfort.
Advancements in the design and materials of peripheral catheters have improved their safety and comfort over time. These improvements include developing materials better suited for extended venous dwell time, mechanisms to prevent needle-related injuries, and securement devices, extension sets, stopcocks, and hubs. 3 The equipment needed for catheter insertion and maintenance varies, often consisting of multiple components that must be connected either before or after insertion. However, the manipulation of these components can introduce several issues. For instance, breaches in aseptic technique during this process can lead to the introduction of microbes into the patient's bloodstream, potentially causing insertion-related bacteremia. Previous studies have shown that Staphylococcus aureus is present in 7.6% to 23.5% of such cases.4,5 Catheter movement during manipulation can also result in dislodgment and loss of venous access. 3 One type of peripheral catheter, known as an open system, features a hub with an open end. These systems require additional components to complete the IV circuit, some of which are packaged separately. In open-system catheters, blood can flow out of the cannula and the open hub during venous access, leading to blood spillage and potential contamination. To address this, newer open-system catheters include features to prevent blood flow out of the hub after insertion, reducing the risk of blood spillage.
Another type of peripheral catheter is the closed system, which integrates an extension tube that contains blood flow within the circuit during cannulation. This design helps prevent blood spillage and needle-stick injuries. Closed-system peripheral catheters are self-contained units that do not require additional components for the IV circuit, reducing common points of contamination. Some closed-system peripheral catheters also include an integrated stabilisation platform to secure the catheter's position, which may help prevent dislodgment or injury to the vein.
