Real-Time 3-D Ultrasound Speeds Patient Recovery

Mayo Clinic physicians have adapted real-time 3-D ultrasound imaging devices -- including one designed to look at an infant's heart -- so that they can watch as they use a needle filled with anesthetic to numb individual nerves located inches under the skin. In this way, they can quickly block nerve function in selected areas of the body prior to surgery, an advance that may spare patients from use of general anesthesia and sends them home faster and with less need for pain medication.

Mayo anesthesiologists have demonstrated the benefits of real-time 3-D ultrasound in nerve blockade in more than 150 surgeries of varied types. Their presentations at scientific meetings and publications in peer-reviewed journals have informed other physicians worldwide into how this next-era ultrasound imaging technology may assist in peripheral nerve block placement -- the technique of disabling targeted nerves so that a patient doesn't feel pain from surgery.
