小儿臂丛神经阻滞新进展

Advances in children brachial plexus block

目前神经刺激仪和超声影像引导等辅助定位周围神经的技术已经广泛应用于区域神经阻滞麻醉,日益受到麻醉医师的重视,但在小儿中的应用报道较少。本文就小儿臂丛神经的解剖特点和对麻醉的影响,臂丛神经阻滞的定位方法、穿刺入路及小儿常用局麻药的代谢特点等方面进行简要综述,以便更好地指导臂丛神经阻滞在小儿麻醉领域中的临床应用。

Nowadays the technology of nerve stimulator and ultrasound imaging guide that fixed position of peripheral nerve which widely used in regional nerve block anesthesia. It took attention increasingly by the anesthesiologist. But it was little reported in the children application. In this paper, the anatomical features of pediatric brachial plexus and influence on anesthesia, positioning method for brachial plexus, vascular approaches, and the metabolic characteristics of children commonly used anesthetics were reviewed in order to guide clinical application in the field of brachial plexus block in children anesthesia.
