Ultrasound-Guided Regional Anesthesia Using a Head-Mounted Video Display: A Randomized Clinical Study
Pain Physician. 2021 Jan;24(1):83-87.Twelve patients were randomized to receive a regional anesthetic performed by anesthesiologists using a head-mounted display (HMD) in addition to the conventional ultrasound-guided approach (n=12) or conventional ultrasound-guided approach alone (n=12). The outcomes of interest included the time to acquire a satisfactory nerve stimulation, number of attempts, number of head rotations to the ultrasound machine screen, and the incidence of adverse events. Results revealed statistically significantly faster time to acquire a satisfactory nerve stimulation, fewer movements, and fewer number of attempts in the HMD group compared to the control group (p<0.05 for all). No complications in either group were noted.
