Pen Torch Transillumination: Shedding Light on Difficult Venepuncture
In Brief
A clinical study evaluating Veinlite, Pen-torch Transillumination, and 1 other intervention for Disorder of Vein. Completed, enrolled 69 participants across 1 site.
Detailed Summary
Our novel technique of pen-torch transillumination (PTI) uses a cheap and easily available instrument (Penlite-LP212®, Energizer®, Missouri, USA) to visualize superficial veins invisible to the naked eye. The investigators evaluate the efficacy of PTI in improving venepuncture success rate (SR) for patients with poor venous access. This prospective randomized controlled trial looks at adult patients aged 21 to 90 with difficult venous access (history of ≥3 consecutive attempts required for successful cannulation during the current admission) requiring non-emergent venepuncture. Patients will undergo venepuncture over the upper-limb using one of the following: Conventional venepuncture (control); Veinlite® (TransLite®, Texas, USA), a commercial transillumination device; PTI. Outcome measures are: successful cannulation within 2 attempts; duration of each successful attempt. Fisher's exact and Kruskal-Wallis tests will be performed.

Timeline
Interventions
Veinlite is a device that emits red light. It provides a non-invasive technique of inserting intra-venous cannula. Placing it onto the skin will cause the outlines of the veins to show up.
Pen-torch Transillumination is a non-invasive technique that utilizes 2 pen-torches to provide illumination.The tips of the pen torches are pressed onto the skin, causing the silhouette of the vein to show up
This involves the conventional method of identifying veins suitable for venepuncture, which involves visualization and palpation.
