OBJECTIVE
To design and fabricate a device to simulate evoked thumb adduction in response to ulnar nerve stimulation.
METHODS
We implemented a computer-controlled, motorized thumb (TWITCHER) that responds to ulnar nerve stimulation by an unmodified peripheral nerve stimulator. Clinically realistic response patterns are generated for both depolarizing and non-depolarizing muscle relaxants and three modes of stimulation (single twitch, train-of-four, tetanus).
RESULTS
The device has been used in a full-scale patient simulator for the last six years.
DISCUSSION
TWITCHER has been well received by participants in simulation exercises including the use of neuromuscular blocking drugs.
目的
设计并制造一种装置，以模拟尺神经刺激引发的拇指内收反应。
方法
我们制作了一种计算机控制的电动拇指装置（TWITCHER），它能对未经改装的外周神经刺激器发出的尺神经刺激做出反应。对于去极化和非去极化肌肉松弛剂以及三种刺激模式（单次颤搐、四个成串刺激、强直刺激），均可产生符合临床实际的反应模式。
结果
在过去六年中，该装置已在全尺寸患者模拟器中使用。
讨论
TWITCHER在包括使用神经肌肉阻滞药物的模拟训练中受到了参与者的好评。
