Patients undergoing surgery require anesthetics or painkillers, sedatives, etc. due to physical and psychological discomfort, but excessive amounts can cause toxic reactions and side effects.
On December 20th, Dr. Zhang Qiang Group successfully performed varicose vein surgery in the VR assisted bureau in Beijing. During surgery, the concentration of lidocaine (a local anesthetic commonly used in medical clinics) was reduced to 0.25%, which is 1/4 of the conventional concentration (1%), and the patient's heart rate and blood pressure were stable with no significant pain.
It is said that after the application of VR, patients with varicose veins wear VR heads during the operation, watching panoramic video, physical pain and psychological anxiety can be effectively alleviated, and they can go home about 1 hour after surgery.
“These virtual images are completely 360° stereoscopic. The falling leaves, the flying butterflies, and the natural sounds mixed in the light music are all specially made.†Dr. Zhang Qiang said that when the doctor completed the surgery for the patient, the patient saw the VR. The scene will also just end.
This is likely to be the first two cases in the world and the only two cases of VR-assisted local anesthesia varicose vein surgery, which is of great significance in the domestic clinical application of vr technology.
In the future, VR videos of different durations can be designed according to the severity of the patient's condition, and different scenarios such as underwater world and space travel can be developed according to user feedback and preferences. In addition to varicose veins, VR can also be used in other disease treatment areas, such as depression, rehabilitation therapy, and first aid.
