The study was designed as a prospective, observational study. Pediatric patients under 18 years of age scheduled for peripheral vascular access placement during day-case surgery or non-operating room anesthesia (NORA) will be included. The primary outcomes include time to successful vascular access, number of attempts, and number of interventions (defined as each new skin entry of the needle). These outcomes will be compared between two groups: those who receive vascular access with the aid of a vascular imaging device and those in whom such a device is not used.
