INTRODUCTION: 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. We evaluate the efficacy of PTI in improving venepuncture success rate (SR) for patients with poor venous access. METHODS: This prospective randomized controlled trial looked at adult patients (n = 69) aged 21-90 with difficult venous access (history of ≥3 consecutive attempts required for successful cannulation during the current admission) requiring non-emergent venepuncture. Patients underwent venepuncture over the upper-limb using one of the following: conventional venepuncture (control); Veinlite® EMS (TransLite®, Texas, USA), a commercial transillumination device; PTI. Outcome measures were: successful cannulation within 2 attempts and total duration of venepuncture. Fisher's exact and Kruskal-Wallis tests were performed. RESULTS: A significantly larger number of patients had successful venepuncture within 2 attempts using PTI (22/23, 95.7%) and Veinlite (23/23, 100%), compared to the controls (7/23, 30.4%) (p < 0.05). The total duration required for successful venepuncture was significantly shorter for Veinlite (mean 3.7 min, 1.0-5.3 min) and PTI (mean 8.5 min, range 1.08-27 min) compared to the controls (mean 23.2 min, range 1.88-46.5 min) (p < 0.05). CONCLUSIONS: PTI allows users to visualize veins invisible to the naked eye. Thrombosed/tortuous veins, branch points and valves, are easily identified and avoided. It has comparable efficacy to Veinlite® and is cheaper (Veinlite®-USD 227 vs. Penlite-LP212®-USD 7.00) and more easily available. PTI improves patient care, especially in developing regions where costs are a concern.
