Impact of Virtual Reality in Hematology and Oncology During Invasive Procedures in Children, Adolescents and Young Adults, from 7 to Less Than 25 Years Old

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.

Nationally, around 2,150 new cases of cancer are diagnosed per year in children aged 0 to 18. The main locations are leukemia, central system tumors and lymphomas. The onco-pediatrics unit of the Poitiers University Hospital is recruiting around 70 patients per year from 0 to under 18 years old. 1482 invasive procedures have been done in 2019. The diagnostic and therapeutic methods for these children remain aggressive and involve patients in chronic care. They repeatedly undergo painful and anxiety-inducing care. In pediatrics, nitrous oxide is chosen as the first-line choice in these various procedures, but its effectiveness is not always conclusive, due to habituation, and can induce side effects. For some children, it becomes difficult to obtain their consent to care, despite the range of different analgesics offered, and forces prescribers to increase the drugs. Virtual reality (VR) has already been shown to be effective on pain and anxiety in children and adolescents. This devices uses distraction and hypnosis techniques by establishing a state of hypnosedation and mediation through the work of breathing and sophrology. With this study, we expect the same benefit by using VR as usual pratices.

After explaining the treatment protocol, the potentially eligible patient will be informed by the investigator of the possibility of participating in this clinical trial. After checking the eligibility criteria and including the patient, the investigator can randomize the patient in the control group or the experimental group. As part of this study, patients will be followed for 1 month and for each act of lumbar puncture and connection to an implantable chamber.

* Child informed and having given his assent

Exclusion Criteria:
