Peripheral intravenous cannulation is one of the most common procedures performed in children admitted to hospital. It is a painful and anxiety-provoking gesture for children with possible memorization of the pain even more present for patients with chronic pathology. Nevertheless, this care is essential to administer the treatments. The cannulation is usually set up by the observation and touching of the veins by the nurse. However, this technique is often insufficient in young children and especially infants because they have a higher thickness adipose tissue. Their veins are of small caliber, hardly visible and palpable which increases the probability of a failure of the insertion of the catheter at the first attempt. In the literature, different techniques are mentioned to promote the visualization of veins and thus the insertion of cannulation. The AccuVein®400 (AV400) system uses an infrared laser beam to project the image of superficial veins to the skin. In adults, AV400 has been shown to improve the success rate of insertion cannulation when venous capital is precarious. The question now arises as to whether this tool could be of interest to children who are particularly difficult to assist cannulation, especially the youngest of them. Investigator hypothesize that AV400 could bring a benefit to the placement of cannulation, in the child with a venous capital difficult to catheterize and thus increase the success of the cannulation at the first attempt.
