Real- time guidance is provided. Proper and purposeful needle movement, proper adjustments in direction and depth is possible. It improves the quality of sensory block. The onset time is set. The success rate is better improved while compared to nerve stimulator technique. The pulsed echo is in brief bursts. The signals returning to the transducer is compressed and amplified. The memory is stored with video images. In all modern surgical techniques the use of Ultrasound guided regional anesthesia is becoming more popular. It is envisaged that the use of medical ultrasound is the next big growth area in medical training hopefully giving real benefits to patient care.
