We measured EMG changes during both upward and downward tube dislocation (10\u201320 mm) and rotation (45\u201390\u00b0) with continuous neuromonitoring.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The EMG amplitude varied significantly with induced endotracheal tube rotation and depth changes. However, the EMG latency was relatively unaffected by such tube dislocation, just a transient artifactual latency change was observed in the situation of extreme amplitude variation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Amplitude changes without latency changes may be due to changes in tube position alone during surgery, but could still reflect a neurophysiologic event; amplitude changes during neuropraxic injury merit additional investigation. Thus, the combined event (concordant amplitude decrease and latency increase) serves as an appropriate adverse EMG event correlating with impending neural injury. \u00a9 2015 Wiley Periodicals, Inc.
