Monitoring of neuromuscular transmission by electromyography (II)

Abstract: The feasibility of the compound electromyogram (EMG) was evaluated during onset and recovery from pancuronium block in the tibialis anterior muscle of ten cats. The evoked EMG area, amplitude and duration of the total response and of the major negative deflection were evaluated and compared to the mechanomyogram during 0.1 Hz and train-of-four (TOF) stimulation. EMG areas and amplitudes were found to be linearly and similarly related to the mechanomyogram during onset and recovery. Slopes of the regression lin… Show more

“…Third, tetanic stimulation was not included in the calibration protocol to prevent the staircase phenomenon typical of acceleromyography (amplification induced by repetitive stimulation). 46 As EMG is less subject to baseline drift, 47 we attempted to test the TetraGraph monitor in everyday clinical settings, and we omitted this step, which is not part of routine clinical practice.…”

“…35,44 Although the temperature affects the twitch height (T1), the TOF ratio is not affected. 43 This lack of effect of temperature on the EMG TOF ratio is unlike the marked TOF ratio depression of 20% per C temperature decrease seen with MMG. 45 Manufacturers' recommendations for monitor setup should be followed.…”

“…EMG area under the curve and amplitude appear to reflect neuromuscular transmission equally. 43 The principal disadvantage of EMG monitoring is the signal drift which may partly be a function of hand temperature. 44 However, the drift (approximately 2%-8% decrease in T1 height per C increase) can be compensated for by normalization of the twitch height value after the temperature is stabilized.…”
