Virtual Reality Reduces Medical Anxiety and Pain in Children

Virtual Reality Can Ease Medical Anxiety and Pain in Children

Two studies recently presented at the annual meeting in San Francisco of the American Society of Anesthesiologists show that virtual reality can reduce children’s anxiety and pain before and after medical procedures and surgery.

Researchers also believe use of virtual reality may be beneficial in a variety of care settings including child birth, physical therapy and a variety of health care scenarios that involve pain management.

In the new report, one study found virtual reality that induces a hypnotic state helped manage postoperative anxiety and pain in children. A second study suggests that a novel virtual reality program that has the ability to adjust the amount of information that is being processed when a child changes position during medical procedures may reduce their anxiety and perception of pain.

In the studies, researchers discovered virtual reality hypnosis reduced the need for anxiety, and pain medications after surgery.

Specifically, the first study found virtual reality hypnosis (VRH) reduced anxiety, total postoperative opioid consumption and vomiting in children after scoliosis surgery. Twenty-one children were included in the study. Ten children received VRH support after surgery in addition to usual postoperative pain management, which included patient-controlled analgesia with opioids, while 11 children did not receive VRH.

“It’s been well documented that reducing preoperative anxiety correlates with reducing postoperative pain,” said study co-author Girish P. Joshi, M.D., professor of anesthesiology and pain management at the University of Texas Southwestern Medical School, Dallas.

“To our knowledge, this is the first study to assess the postoperative use of virtual reality hypnosis in children. Our goal is not only to decrease pain, but also to decrease opioid use.”

The children receiving VRH participated in one session per day for 20 minutes during the first 72 hours after surgery. They wore a helmet and goggles linked to software, which uses virtual reality hypnosis technology to decrease stress and anxiety after painful medical procedures.

The children chose a scenario — beach, submarine or walking in the mountains — and heard soothing speech and music to induce hypnosis.

The VRH group had a significantly lower need for pain and anxiety medications. Only 20 percent in the VRH group required pain medication (IV morphine), compared to 62.5 percent in the control group, while 37.5 percent of the VRH group required anti-anxiety medication, compared to 100 percent in the control group.

Total postoperative IV morphine consumption over 72 hours after surgery was significantly less in the VRH group.

“Morphine is associated with a sedating effect that may prevent patients from eating and walking sooner,” Joshi said. “The significant reduction in morphine use seen in patients given VRH means they can have a quicker recovery.”

Children in the VRH group were able to sit up and/or walk more quickly after surgery (23 hours compared to 33 hours in the control group), another important sign of recovery, noted  Joshi.

Additionally, children in the VRH group experienced less vomiting (40 percent vs. 83.3 percent in the control group) and their urinary catheters were removed sooner (20 hours vs. 41 hours in the control group). Total hospital length of stay was 125.5 hours in the VRH group compared to 137.7 hours in the control group.

“We are very encouraged by the initial findings in this pilot study,” Joshi said. “Next we need to conduct a randomized controlled study. 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.”

The second study examined over 600 patients, ages 6 to 18 years old, who were given a novel virtual reality (VR) game, which allows the user or clinician to reorient the game play in real time and adjust cognitive load to increase its ability to distract patients, so their perception of pain is decreased.

“We have known for years that pain and anxiety are highly correlated,” said study co-author Thomas J. Caruso, M.D., clinical associate professor, anesthesiology, perioperative and pain medicine at Stanford University, California.

“If someone is extremely anxious about something that is about to occur, they are more likely to report pain. Our goal is to distract our pediatric patients to reduce their anxiety and perception of pain.”

The program was launched in 2017 as part of CHARIOT (childhood anxiety reduction through innovation and technology), a Stanford University program that uses VR in a variety of settings, both in the hospital and clinic, to distract patients during periods of high anxiety such as IV placement, blood draws, IV-port access or dressing changes.

The researchers developed the new VR platform in response to a problem they had encountered when using other VR programs — when a patient changed position, such as going from lying down to sitting, existing VR technology did not change position along with them.

“During a typical VR experience, when you look up, you are looking at the sky,” explained study lead author Samuel Rodriguez, M.D., clinical assistant professor, anesthesiology, perioperative and pain medicine at Stanford. “The reorientation feature that we developed allows the horizon line to be reoriented every time the patient’s head position changes.”

The program also adjusts the patient’s cognitive load, which means using faster music, more colors or increased game play to increase the game’s ability to distract in order to reduce anxiety. It is used primarily before and during minor medical procedures such as IV placement, wound care, cast or surgical pin removal and nasal endoscopy, typically for 2 to 20 minutes.

“Preliminary results have suggested our new VR game decreases anxiety and patients’ perception of pain,” Caruso said.
