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.
