Comparison of the Effectiveness of Ultrasound-guided Techniques and Infrared Illumination, Compared With the Standard Approach to Peripheral Venous Line Placement in People With Difficult Venous Access

This is a prospective, controlled, randomized, three-arm, single-center, superiority trial involving patients with difficult venous access.

Control group: Classical method based on clinical examination (visualization and palpation).

Experimental1 group: Ultrasound-guided method. Experimental2 group: Infrared illumination method. A total of 249 patients will be enrolled, with 82 patients in each group. The inclusion period will last 12 months, and each participant will be involved for a maximum of 4 hours. The total duration of the clinical investigation will be 1 year and 4 hours.
