The Vascular Access Unit (UAV) of the Lyon Sud Hospital Center is the first unit within a French public establishment where the Regional Health Agency (ARS) has authorized that medical procedures for the installation of central venous access be performed by nurses.

The installation of CIP represents an anxiety-provoking step for the patient, because the gesture, which consists of inserting a box under the skin, connected to a catheter, placed in a deep vein, involves uncomfortable, even painful moments. In the UAV, the installation of this device is carried out in the operating room, without premedication and only under local anesthesia. Affected patients usually have a diagnosis of serious illness (oncology).

Virtual Reality (VR) simulates the physical presence of the patient in an environment artificially generated by software. Many applications have already been evaluated in different health sectors, the investigators would like to show its interest in reducing patient anxiety during CIP placement under local anesthesia, without premedication.

The medical device used is Lumeen. It is a Class I medical device software within the meaning of Regulation (EU) 2017/745, CE marked. In the context of research, the Relaxation module is used. This module is the one intended for the management of anxiety and pain induced by medical procedures in adults and children over 6 years of age. It allows to perform immersions in 360° videos in real shots or computer-generated images, accompanied by natural sounds, relaxing music and a relaxation script recorded by hypnotherapists. The duration of an immersion can be adjusted according to the needs of the medical procedure..
