sonoprepUltrasonically opening up cavities in the skin doesn't really sound good, but the FDA just approved the SonoPrep, which creates "channels" in the skin to help speed up delivery of anesthetics like lidocaine. It normally takes about an hour for painkillers to work, but the Sonoprep cuts that to just five minutes, making pin pricks from medical procedures a lot more tolerable.
