Practice and Use of Digital Sedation

In the waiting room of a surgical service or a vascular access unit, patients can benefit from a new device to help them relax before the surgical procedure. The medical team can give them the option of wearing a virtual reality headset and to go on a trip. They can go scuba diving in the bottom of the oceans with a whale or enjoy a pleasant walk in the woods, far from bad weather. The Digital Sedation™ is based on stylized images, yet realistic. They are in 3D and in 360°. The relaxing music, the breathing exercises and the narration help them distress. The very immersive nature of this high-tech material allows an adhesion of the patient that is almost constant. It is intuitive and easy to use. It is more than a simple relaxation or distraction since it has the effects of self-hypnosis with a period of induction, maintenance, anchoring and awakening. The time and duration of the application can change depending on the needs.

For the past few years, the use of virtual reality has been increasing in the world of health, neurology, re-education, psychiatry, treatment of neurosis, phobias and now, in the interventional radiology suites and operating rooms. Virtual reality is quite different from augmented reality: In virtual reality, the patient is inside a virtual environment whereas in augmented reality, the objects become visible on beside real elements.


Digital Sedation Bibliography

However, there is still a lack in bibliography about it. 3 major journals are available1,2,3 and confirm the efficiency of the techniques of virtual reality. They confirm the importance of the quality of the devices: the headphones, the mask, and the software. The experimental studies are mainly based on healthy volunteers but its effectiveness is represented in imaging during functional MRI4 . On the clinical aspect, the efficiency of virtual reality is now recognized. Its use is recommended when it comes to burn dressings5. Its use is also expanding to surgery units: in urology6, orthopedy7, breast surgery8, and vascular access9,10,11.

In our own experience, we have been testing since 2014 this device in the preoperative period, and almost all the subjects have stated that their anxiety diminished by more than 50%, based on the evaluation scale that was proposed to them.


Digital Sedation Use

These devices are now alternatives to premedication or sedative and anti-anxiety drugs. Moreover, they can replace clinical hypnosis that is time consuming and that can’t always be proposed to patients, considering the time it takes or the lack of availability, despite the rising number of trained healthcare professionals.

The Digital Sedation™ is an alternative therapeutic solution that can be adapted to various clinical situations by adapting to the patient’s age (from 6 years), duration and type of intervention.

This technology is also of interest and valuable during chemotherapy to manage patient anxiety and provides a better patient experience of his care pathway.


Healthcare workers’ role

In practice, healthcare workers have an essential role in the reception of patients during this experience, that is sometimes the first one that they would go through. The commitment of the healthcare workers and the affirmation of their availability during the act are success guarantees. The headset is placed on the patient’s head a few minutes before the act to let some time for the hypnotic induction. Contact is kept during the act. The operator or the assistant caregiver can for instance let the patient know in a calm tone when it is time for local anaesthesia, venepuncture, or the creation of the subcutaneous pocket of a port. A time distortion is often noticed: patients assess an intervention time shorter than reality.

Calmness that can easily be acquired by patients can also spread to the care teams.

Self-hypnosis or Digital Sedation™ through virtual reality in health care facilities is no longer virtual and not yet well established, but real and effective. It must be integrated in the care units and in the patients’ care process.
