The goal of this clinical trial is to learn if using near-infrared imaging in pediatric vein cannulation is leading to higher success rate. The main question it aims to answer is:

is there higher success of first attempt in periferal vein cannulation? does it lower overall number of attempts to successful cannulation?

Providing venous access in pediatric anesthesia and intensive care is among the basic and necessary interventions for blood sampling and administration of drugs and possibly transfusion products and derivatives.

In anesthesia, effective provision of venous access is a prerequisite for safe anesthesia. In pediatric patients and newborns, provision of venous access is complicated by patient non-cooperation, but primarily by the smaller diameter of the vessels and often limited possibility of direct visualization, or limited possibility of palpation of the vessel under visual control. Ultrasound is currently used to facilitate provision of IV access, however, imaging under the USG probe and its subsequent puncture requires high skill of medical personnel and is preferentially applied by medical staff in the conditions of the Czech Republic. Near-infrared imaging (IR) allows direct visualization of superficial vascular bed and may potentially be associated with higher puncture success rates (higher first attempt success, reduction of total attempts).
