the effect of virtual reality on post-surgical pain and recovery.

Conditions: Pain; Post-surgical Pain; Pain Management

Summary: this study evaluates the effect of virtual reality (vr) on pain and recovery in 100 post-operative patients. 60 patients will be included in the intervention group; they will use vr minimal 3 times a day on day 2-4 after surgery, on the surgical ward, as an add-on intervention next to standard care. 40 patients in the control group will only receive standard postoperative care.

adequate management of post-surgical pain (psp) may contribute to improved clinical and socioeconomic outcomes. facilitating an adequate level of psp relief is a challenging problem: the analgesics that are most frequently used, for example, opioids and non-steroidal anti-inflammatory drugs (nsaids), often come with side effects and do not always provide sufficient pain relief. therefore, pain management is increasingly focusing on (additional) non-pharmacological analgesics, including virtual reality (vr). vr immerses the user in a virtual world through a head mounted device (hmd). vr is, among other things, taught to be effective through distraction: it diverts attention away from the nociceptive input, resulting in less available attention for pain perception. in both clinical and experimental studies, vr has shown to be effective in reducing pain, anxiety and stress. although this distraction method is increasingly studied in the past years, vr pain relief has mostly been investigated as an intervention during painful procedures in specific research populations. for example, vr has been studied during wound dressing changes in burn wound patients in children and adolescents, during venipuncture in children or during dental treatments. furthermore, most vr studies used vr as a single intervention, measuring pre-post differences in pain scores or used a cross over design with one vr session and one control session. it is interesting to know whether vr is effective in reducing postoperative pain during more than one vr session. more research is needed in larger trials evaluating a broad sample of the general population including elderly, as the common hospitalized patient is of an older age nowadays. finally, it is important to evaluate the feasibility and acceptability of vr in postoperative patients and to know whether there are predictive factors to select patients who can mostly benefit from vr interventions.

Eligibility criteria:
inclusion criteria: * patient underwent surgery * patient reports a postoperative pain score ≥4 on the first postoperative day at the surgical ward and pain score should also be marked with 'pain is not acceptable'. * at the day of recruitment, the estimated length of stay is at least 4 days after inclusion. * patient is willing and able to comply with the trial protocol. * patient is at least 16 years old on the day the informed consent form will be signed. exclusion criteria: * patient suffers from delirium or acute confusional state. * patient has (a history of) dementia, seizure or epilepsy. * patient with severe hearing/visual impairment not corrected. * patient is placed in isolation. * the skin of the patient's head or face is not intact (for example head wounds, psoriasis, eczema). * unplanned (re)admission to the intensive care unit (icu). * inclusion in another trial to evaluate new ways of treating pain
