神经刺激作为神经定位方法的发展在30年前引发了区域麻醉的复兴，就像最近使用超声一样。然而，尽管广泛使用超声波和神经刺激器，神经损伤继续发生。1，2这两种技术都只能不完全地说明针相对于目标神经的位置，因此，都不能可靠地识别针的神经内位置。尽管如此，最近的研究已经能够更好地定义神经刺激的局限性，并产生了新的概念，随着进一步的发展，可能使我们能够避免神经损伤。本文将从阻抗、阈值电流、极性、组织-针界面等方面综述神经刺激的新认识和进展。
The development of nerve stimulation as a method of nerve localization sparked a renaissance in regional anesthesia 30 years ago, as the use of ultrasound has in more recent times. However, despite widespread use of ultrasound and nerve stimulators, nerve injury continues to occur. 1, 2 Both of these technologies allow for only imperfect elucidation of needle position relative to the target nerve, and therefore, neither is reliably able to identify intraneural position of the needle. Despite this, recent research has been able to define better the limitations of nerve stimulation and has produced new concepts, which with further development may enable us to avoid nerve injury. This article will review the new understandings and advances in using nerve stimulation in respect to impedance, threshold current, polarity, and tissue-needle interface.
