Pain during medical procedures is often excessive. Despite aggressive use of opioid analgesics, the majority of burn patients report severe to excruciating pain during wound care. Opioid side effects often preclude adequate pharmacologic analgesia during burn wound care and during a number of other medical procedures (e.g., treatments for cancer patients, dental fear/pain, etc). I will present results from a few clinical studies I have published with Dave Patterson and others, exploring the use of immersive virtual reality as a non-pharmacologic adjunct, used in addition to traditional opioids. We propose that VR distracts patients from their pain during wound care and physical therapy by luring their spotlight of attention into a virtual world named “SnowWorld”. In SnowWorld, patients throw snowballs at Snowmen, igloos, robots and penguins, by aiming with their gaze. .The essence of immersive virtual reality is the user’s illusion of going into the virtual world. In a different project involving spider phobics,, the place patients go in VR is SpiderWorld. I will briefly describe the use of virtual reality exposure therapy for treating people with clinical spider phobia, and a third project where we used VR exposure therapy for treating Manhattan survivors of Sept 11th who have developed severe (clinical) Post-Traumatic Stress Disorder (treated with an immersive computer-simulation of Sept 11th).
