Fonte: aqui.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.
