Hypnosis through virtual reality has been explored by the anesthesiologists at UT Southwestern Medical Center as a means to reduce post-operative pain and anxiety in children. Virtual reality hypnosis (VRH) reduced anxiety, total post-operative opioid consumption, and vomiting in children after scoliosis surgery, found a European-based pilot study involving 21 young patients.
Ten children received VRH support after surgery in addition to usual postoperative pain management, which included patient-controlled analgesics with opioids, while 11 children did not receive VRH.
VRH participation involved one session per day for 20 minutes during the first 72 hours after surgery. The group wore helmets and goggles linked to software developed in France that uses virtual reality hypnosis technology to decrease stress and anxiety. The children got to choose a scenario like a beach, an underwater swim, or walking in the mountains and heard soothing words and music to induce hypnosis.
The study's VRH group demonstrated several significant advantages, including:
Only 20 percent required pain medication (IV morphine), compared with 62.5 percent in the control group.
5 percent of the VRH group required anti-anxiety medication, compared with 100 percent in the control group.
VRH group members were able to sit up and/or walk more quickly after surgery (23 hours compared with 33 hours in the control group).
The VRH group experienced less vomiting (40 percent vs. 83.3 percent in the control group).
The average hospital length of stay was 125.5 hours for VRH group members compared with 137.7 hours in the control group.
"We are very encouraged by the initial findings," Dr. Joshi says. "Our hope is that virtual reality hypnosis will one day be used for most patients undergoing all types of surgeries to reduce postoperative pain and speed recovery.
