Therapeutic Virtual Reality : Impact on the Management of Pain and Anxiety Related to Hematology Care (REVEH)
Therapeutic Virtual Reality : Impact on the Management of Pain and Anxiety Related to Hematology Care (REVEH)
The management of hematological malignancies justifies the completion of a complete
 assessment before the start of treatment. This assessment includes imaging tests (computed
 tomography, position emission tomography, cavitary scintigraphy), biology and very often an
 exploration of the bone marrow by anterior or posterior iliac biopsy. Pains related to the
 disease (node compression, invasion of solid organs) are taken care of at the diagnosis and
 often relieved by the start of the specific treatment.

 However, pain related to medical procedure is often overlooked and can lead to psychological
 trauma in some patients who may refuse to repeat these essential actions to assess the
 response to treatment.

 Anxiety contributes to pain and various relaxation techniques have already proven their
 effectiveness. The goal of the protocol is to reduce the pain and anxiety associated with
 medical procedure by using virtual reality with a helmet proposed at the time of the gesture.
Today, one third of the population suffers from anxiety and 20% of French people suffer from
 chronic pain. Many health situations or pathologies lead to difficult or painful care. The
 impact of drug solutions to relieve patients is often limited and more and more scientific
 studies are demonstrating the benefits of virtual reality to reduce pain, anxiety and
 addictions.

 In 2011, following an experience of close to patient, a person created "l'Effet Papillon", a
 social enterprise that aims to create a concrete social impact in the lives of people with
 cancer, in situations of fragility or isolation and those who accompany them. Since 2011 the
 social enterprise has supported nearly 3,000 patients and today, the Butterfly Effect is a
 real partner of health actors by adopting a holistic approach to wellness in the face of
 disease and fragility.

 Taking full advantage of the benefits of virtual reality that, used in medical settings, can
 reduce pain and anxiety, Bliss is a 3D Interactive application designed to meet the needs of
 escape and relaxation of people in isolation and / or or stress.

 Bliss has been developed for and with patients in partnership with physicians, researchers
 and experts in virtual reality for therapeutic purposes.

 Bliss offer a new tool for relaxation and well-being that relaxes and distracts users from
 moments of stress or anxiety.

 During the osteo-medullary biopsy the patient will lie on his stomach with his hands
 positioned under the head. This position is the one recommended by the French Society of
 Hematology for an osteo-medullary biopsy.

 The osteo-medullary biopsy remains independent of the object of the study and will be carried
 out according to the national recommendations.

 For patients randomized to the "Standard" arm, the treatment will be the same as that
 proposed outside the study (a gas mixture composed of 50% Nitrous Oxide, 50% Oxygen + 1
 bottle of xylocaine® 20 mL at the concentration of 10 mg / mL).

 For randomized patients in the "Virtual Reality" arm, the VR session should begin 5 minutes
 before the start of the procedure (+ 1 bottle of Xylocaine® 20 mL at a concentration of 10 mg
 / mL). The VR session will last between 15 and 30 minutes depending on the speed programmed.
 The patient can continue the session if the gesture ends before the end of the virtual
 reality program.

 The goal of the protocol is to reduce the pain and anxiety associated with medical procedure
 by using virtual reality with a helmet proposed at the time of the gesture.
