MIT News reported that researchers from Beth Israel Deaconess Medical Center in Boston published a study that showed that patients wearing VR head displays needed less anesthetic during hand surgery. Regular patients need 750.6 mg of sedative propofol per hour on average, while those who watch relaxing VR content (such as meditation, natural scenes and videos) only need 125.3 mg. In addition, patients wearing VR head displays also recovered earlier, leaving the post anesthesia ward after 63 minutes on average, compared with 75 minutes for conventional patients. IT Home learned that researchers claim that VR distracts patients from pain, but they also admit that head display wearers have expected VR to help when entering the operating room, which may distort the experimental results. ▼ A is the surgical experiment scene, and B is the VR image. However, the team of Beth Israel Deaconess Medical Center is planning to eliminate this comforting effect. A follow-up trial will also assess the impact of VR on patients undergoing hip and knee surgery. In past experiments, such as the experiment in St. Joseph's Hospital in France, this technology can really help relieve patients' emotions. (Liu Xinshe)
