This pilot study will be testing the feasibility of medical hypnosis through virtual reality during invasive médical procédures in children and young adults with cancer. Patients age from 7 to under 25 years whose treatement protocols required a lumbure puncture and a chemotherapy by implantable venous access will be randomly assigned to virtual reality or treatement as usual (nitrous oxide, anxiolytics, opioid analgesics, psychotropic and benzodiazepine). We expect the same benefit by using VR as usual intervention.
Patients aged 7 to strictly under 25
