Virtual Reality + Olfactory Intervention for Postoperative Pain and Anxiety

This trial explores a new method to manage pain and anxiety for individuals undergoing heart or lung surgery. Instead of relying on drugs like opioids, which can cause serious side effects, the study tests a combination of virtual reality and pleasant scents (Virtual Reality and Olfactory Stimuli Multimodal Intervention) to determine if they improve patient well-being before and after surgery. Participants will either receive this new therapy or continue with their usual care. This trial suits those scheduled for specific heart or lung surgeries, provided they do not have extreme blood pressure issues or allergies to scents. As an unphased trial, it offers patients the opportunity to explore innovative therapies that could enhance their surgical experience.

The trial information does not specify if you need to stop taking your current medications. It seems you may continue your usual medical care, but it's best to confirm with the trial coordinators.

Research shows that using virtual reality (VR) with pleasant smells can help reduce pain and anxiety. Although this method is new, early studies suggest it is safe for people. VR is often used for anxiety without serious issues. Pleasant smells are generally well-tolerated as well. Overall, reports of significant negative effects from combining VR and scents are lacking. This approach offers a promising option for managing pain and anxiety without the side effects of traditional medications like opioids and benzodiazepines.¹²³⁴⁵

Researchers are excited about the Virtual Reality and Olfactory Stimuli treatment because it combines immersive technology with scent therapy to tackle postoperative pain and anxiety in a new way. Unlike traditional pain management options, which often rely on medication, this approach uses virtual reality to distract and engage the mind, while olfactory stimuli can have a calming effect, potentially enhancing overall patient comfort. This multimodal intervention is non-invasive and could provide a complementary or alternative option to pharmaceuticals, offering a holistic way to manage recovery.

Research has shown that virtual reality (VR) can lower pain levels and increase pain tolerance in people with chronic pain. Studies suggest that combining VR with pleasant smells might reduce pain and anxiety more effectively than some medications, such as opioids and benzodiazepines, which can cause side effects. A review of several studies found that VR slightly reduced anxiety before surgery. Another study indicated that olfactory virtual reality (a combination of VR and scents) improved well-being and reduced stress, anxiety, and pain for hospital patients. In this trial, participants in the Virtual Reality and Olfactory Stimuli Arm will experience this combined approach, which could be a promising way to manage pain and anxiety around surgeries.²³⁴⁵⁶
