BACKGROUND AND OBJECTIVE: The Datex-Ohmeda neuromuscular transmission module (M- @entity32597 ) is a new monitor that is part of the @entity5427 /3 anaesthesia monitor. It incorporates a mechanosensor, which is a piezoelectric polymer attached to the hand. The module was compared with a force transducer in 30 @entity1 requiring @entity4094 . METHODS: Anaesthesia was induced with @entity3575 and @entity1875 , and tracheal intubation was performed without muscle relaxants. @entity4094 was assessed by the test module on one arm and the force transducer on the other arm. When the response to train-of-four stimulation had been stable in both arms for 3 min, @entity2898 0.2 mg kg(-1) was injected intravenously. During recovery from blockade, the train-of-four ratio was measured in 15 @entity1 , and the ratio of response to double-burst stimulation in the other 15 @entity1 . Data analysis was by difference plots. RESULTS: Both devices had acceptable coefficients of repeatability. The M- @entity32597 module was biased by + 1.3% (upper limit of agreement 14.2%, lower limit -12.9%) for the recovery of the train-of-four ratio, and by + 1.09% (17%, -16%) for the recovery of double-burst stimulation ratio. CONCLUSIONS: The Datex-Ohmeda M- @entity32597 gives measurements that are repeatable and gives good enough correspondence with a force transducer that it can be used clinically to assess recovery of @entity4094 , but the limits of agreement rule out research applications.
