We compared changes in biopotentials arising from upper facial (FEMG) and abdominal (AEMG) muscles associated with alterations in alveolar enflurane concentration and neuromuscular block. Induction of anaesthesia significantly reduced both FEMG and AEMG mean amplitudes (-60% and -43%, respectively). Neuromuscular blocker-induced abolition of the electrically evoked thenar EMG response did not prevent FEMG and/or AEMG activation during endotracheal intubation. Decreasing the alveolar enflurane… CONTINUE READING
