TOF-tube, a new protection for acceleromyography, compared with the TOF-Guard/TOF-Watch arm board

Summary:Neuromuscular blockade monitoring at the adductor pollicis has become easier using acceleromyography. In order to guarantee a reliable analysis of its acceleration, the thumb movement has to be free and protected from external influences. To this end, we describe here-in two hand fixation- and protection-devices for use with acceleromyography. After a bolus of 0.3 mg/kg rocuronium, we compared acceleromyography data obtained simultaneously on both hands with, on one side, the cumbersome TOF-Guard/TOF-Watch arm board, and the smaller and handier TOF-tube on the other. Results showed little differences between the two devices. Yet, a short and clinically irrelevant delay was observed for TOF-tube data during recovery. This was probably caused by a difference in thumb position and repositioning technique. In conclusion, the more convenient TOF-tube can be used as well as the TOF-Guard/TOF-Watch arm board in daily clinical practice.
