Key Points: Establishing peripheral IV access is an invasive procedure critical to medical care. Despite this, clinicians and many researchers know little about the characteristics of having many or few veins aside from anecdotal reports and experiences.
As life expectancy increases and patients have more procedures throughout their lifetime, vein preservation is seen as a vital long-term task. A device or technique that helps reduce cannulation attempts would be one step towards vein preservation.
Whenever patients’ veins are invisible to regular eyesight, complications can arise. During these difficult cases, blind cannulation and multiple attempts can be frustrating for medical professionals and painful for patients. Unsuccessful peripheral IV cannulation increases the chance of further complications, such as bruising, bacterial infection, extravasation, phlebitis, thrombosis, embolism, or nerve damage. It can also lead to even more invasive procedures resulting in higher rates of infection and requiring more operator skill (e.g. central line placement and peripherally inserted central catheters (PICCs) are alternative, more complex techniques).
Our data analysis has demonstrated the significant enhancement of vein visualisation through the use of a new VueTek’s Veinsite NIR technology. VF consistently improved the average number of visible veins across all patient characteristic categories.
We feel that identifying veins is one step towards cannulating more veins and that successful and timely IV cannulation leads to reduced tissue trauma, reduced economic costs, and higher patient satisfaction.
African-American or Asian ethnicity, and obese weight were all patient characteristic groups associated with decreased vein visibility.
Early identification of patients with difficult IV access will lead to better clinical care, preventing complications and reducing delays in treatment.
