Randomized controlled trial to measure pain experience, side effects and satisfaction of VR following varicose vein, hernia repair and gallbladder surgeries.
While there is substantial evidence supporting the use of Virtual Reality (VR) during dressing changes for burn victims, there are little information of the effect of VR to decrease pain after surgery. Although pharmacological analgesics are popular in clinical practice, this approach usually is associated with side effects, most commonly nausea, cognitive dysfunction, and constipation. Generally, VR effects are based on gate theory of cognitive load, due to the fact that conscious attention is needed to perceive pain and we can process a finite amount of information.High-Tech-VR devices shown to be more effective in reducing pain than are Low-Tech-VR systems (Prothero, J. D., & Hoffman, H. D, 1995). In addition, studies have shown that interactivity play an important role to decrease both, pain unpleasantness and time spent thinking about pain, while increasing fun (Wender, R., et al., 2010, Gromala, D., et al 2011). Thus, interactivity helps patients to have a better immersion into VR world. Considering this, in the proposed study, patients will be randomized to either receive a high immersive and interactive VR environment using Oculus Rift Headset in addition to standard care or to receive only standard care during their post-operative care following surgery to prospectively assess the utility of virtual reality (VR) for pain management following varicose vein, hernia repair and gallbladder surgeries.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Virtual Reality | Experimental | Patients randomized to the experimental group will benefit from the usual standard care following surgery and during the second day the opportunity to use virtual reality for 15 minute. Along VR, they will complete the psychological and physiological measures. |
|
| Non-VR condition (Standard of Care) | No Intervention | Patients randomized to the control group will benefit from the usual standard care following surgery and during the second day will complete the psychological and physiological measures. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Virtual Reality intervention - Oculus Rift HD | Device | During the VR experience patients will have the opportunity to choose from different VR environments (VR application - Nature Treks VR) and explore them using Oculus Rift Device. |
| Measure | Description | Time Frame |
|---|---|---|
| Pain intensity | Graphic Rating Scale measure pain intensity from 1 to 10, 1 - no pain; 10 - worst pain. | Pain intensity before intervention; Change from Baseline pain intensity (immediately following intervention) |
| Pain intensity | Skin conductance response | 5 minutes before intervention (baseline) |
| Pain intensity | Skin conductance response | 15 minutes - During the intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Satisfaction with the intervention | Patient Satisfaction Survey | Immediately following intervention |
| Presence in the VR environment | Presence Inventory assesses the degree of spatial presence, involvement, ecological validity, overall presence, and negative effects experienced during the VR intervention |
