Background: Peripheral intravenous (IV) cannulation is a routine clinical procedure but can be challenging, particularly in patients with poorly visible or palpable veins. Aim: This study aimed to evaluate the effectiveness of an LED vein finder in facilitating IV cannulation in selected hospitals in Puducherry. Materials and Methods: A post-test only control group design was adopted. Sixty adult patients requiring IV cannulation were selected and randomly assigned to two groups: one underwent cannulation using an LED vein finder, while the other received the conventional approach. Outcomes assessed included the number of cannulation attempts, the level of pain experienced, and the perceived difficulty of the procedure. Data were analyzed using descriptive and inferential statistics. Results: Participants in the LED vein finder group required fewer attempts (mean = 1.70) compared to the conventional group (mean = 1.83), reported lower pain scores (mean = 3.57 vs. 4.27), and rated the procedure as less difficult (mean = 4.03 vs. 4.63). These differences were statistically significant. Additionally, correlations were observed between pain, procedural difficulty, and first-attempt success. Conclusion: The use of an LED vein finder significantly improved the ease of IV cannulation, reduced patient discomfort, and increased the likelihood of first-attempt success.
