Patients immersed in virtual reality during surgery may need less anesthetic
A team of researchers at Beth Israel Deaconess Medical Center in Boston split 34 patients undergoing elective hand surgery into two equal-size groups. One group was given a VR headset and offered a range of relaxing immersive programs to view during surgery, while the other went without. The VR programs included 360-degree views of a peaceful meadow, mountaintop, or forest; guided meditation; or videos played against the backdrop of a starry sky.
