[A comparative study of 2 methods of neuromuscular function monitoring, electromyography and acceleromyography, during anesthesia in children].

The responses of m. adductor pollici to TOF stimulation of the ulnar nerve were recorded by electromyography (EMG) and acceleromyography (AMG) in 36 children aged 2-12 years with ASA classes I-II during 36 planned surgeries. In 14 children myoplegia was attained by intravenous bolus and infusion atracurium (Tracrium) and in 22 by cisatracurium (nimbex). The data on the function of this muscle after the initial bolus injection of myoplegics do not provide reliable information on the function of the larynx and respiratory muscles during intubation and do not allow a conclusion on the possibility of endotracheal intubation. The threshold sensitivities of EMG and AMG recording of the neuromuscular function starting from the fifth minute after the myorelaxant injection till the end of anesthesia are different. EMG permits evaluating the recovery of neuromuscular conduction early after the infusion of myoplegics; complete recovery of the block is shown virtually simultaneously by AMG and EMG. EMG as a more accurate method is preferable for research, while AMG is a simpler and stable method, preferable for routine practice.
