Comparison of Dwell Time of Open Versus Closed Type Peripheral Intravenous Cannula

Plain-language summary

Studies have shown that stabilisation devices are associated with fewer complications and lower failure rates in peripheral catheters.3,6,7 Although closed-system peripheral catheters offer potential advantages, such as reduced manipulation of components and minimised blood spillage, more research is needed to understand their impact on outcomes. The ability of peripheral catheters to remain functional and in place without complications is crucial. While various clinical factors influence peripheral catheter performance, the composition and structure of peripheral catheters also affect their dwell time, which is defined as the duration at which the catheter remains functional after insertion. A study by McNeill et al. found that during the preintervention phase, about 62% of open-system peripheral catheters lost IV access within 36 hours, with less than 10% remaining functional beyond 72 hours. The dwell time of closed-system peripheral catheters with a securement device increased to up to 96 hours during the intervention period.8
