We propose to conduct a prospective randomized trial which looks at the effect that VR relaxation has when combined with PCA morphine in a group of patients having potentially painful dressing changes. In addition we want to isolate patients who have high susceptability to hypnosis and compare their ratings of pain, anxiety and opiate requirement with patients of lesser susceptibility. Our hypothesis is that patients with higher susceptibility to hypnosis stand to gain most from the addition of VR to their pharmacotherapy.
