The use of the peripheral nerve stimulator is essential for adequate assessment of the degree of neuromuscular block. To ensure that the data derived are accurate one must understand the effects of stimulus frequency, electrode type, position and polarity, stimulus intensity, duration, waveform and the various ways used to observe the data, electromechanical, EMG, tactile or visual. Once these features are understood, a better interpretation of the various tests is possible. While a lot of information regarding the proper use of the PNS is derived from meticulous scientific experimentation, it is possible to apply this information for clinical use. Most information is available based on ulnar nerve stimulation. Information on stimulation of other nerves (e.g., current to achieve SMS on the peroneal nerve) is lacking. With this in mind, the authors present in Table III the minimum requirements for a PNS and an algorithm to illustrate use of the PNS, in Figure 6.
使用外周神经刺激器对于充分评估神经肌肉阻滞程度至关重要。为确保所获得的数据准确，必须了解刺激频率、电极类型、位置和极性、刺激强度、持续时间、波形以及用于观察数据的各种方式（机电、肌电图、触觉或视觉）的影响。一旦理解了这些特征，就能够更好地解释各种测试结果。虽然关于外周神经刺激器正确使用的许多信息来自细致的科学实验，但将这些信息应用于临床是可行的。大多数信息是基于尺神经刺激获得的。缺乏关于刺激其他神经（例如，在腓神经上实现超强刺激的电流）的信息。考虑到这一点，作者在表III中列出了外周神经刺激器的最低要求，并在图6中给出了一个说明外周神经刺激器使用方法的算法。
