[The History and the Future of Peripheral Nerve Block].

Abstract

Peripheral nerve block became popular with the advance of the ultrasonic diagnostic equipment, and became one of the essential procedures in anesthesia. For the further development of this method, we have to learn the past and identify problems in this course. We have outlined the history of the peripheral nerve block and described the development of the method. Furthermore, we verified the recent change in periph- eral nerve block by searching the literature and exa- min the background. Lastly, we pointed out problems of the current peripheral nerve block and described its new application and its ideal future course.
