NMT Module AF-101P New

Ideal performance for muscle relaxation monitoring

Neuromuscular transmission (NMT) is the transfer of an impulse between a nerve and a muscle in the neuromuscular junction. NMT can be blocked by neuromuscular blocking agents (drugs for muscle relaxation or for causing transient muscle paralysis and prevent patient movement and spontaneous breathing).

The unique and easy to use hand-held controller allows you to operate from a distance while keeping a close eye on your patient. One touch to direct keys gives access to multiple modes, making it really convenient to use. Our fast NMT module provides quantitative, automatic measurement of muscle response to a stimulus with the help of stimulation electrodes, an acceleration transducer, and temperature sensor.

Ease of use

Hand-held controller: A handy controller with four hard keys provides one-touch access to the most frequent operations. The controller lets you operate the NMT module from a distance as well. Also, the module can be operated via the patient monitor.

Quick installation: To install the NMT module, just connect it to the multi-connector on a Life Scope monitor via a Smart Cable. Cable management is easy even when the patient is transported. You can mount the NMT module anywhere by using the clip holder. Durable cables and IPX4 waterproofing help prevent trouble during operation

Complete patient information: The measured values from the NMT module are displayed on the patient monitor, and trended and automatically documented via HL7 output together with all the other monitored parameters.

Measurement: Can be obtained from any nerve or muscle, such as the wrist (ulnar nerve - adductor pollicis muscle), ankle (tibial nerve – flexor halluces brevis muscle), or face (facial nerve – orbicularis oculi muscle), for example.

Clinical support

  • NMT monitoring: Provides complete information of patient’s dosage requirement and facilitates optimal and cost-effective administration of neuromuscular blocking.
  • Different stimulation types include:
    TOF (train-of-four): TOF trend provides complete information displayed on Nihon Kohden’s Life Scope G9, G7, G5, TR, and VS, which helps to prepare the next step, such as intubation, extubation, and dosage of antagonist, which may decrease the incidence of residual paralysis.
    - Single Twitch (one-time stimulation): This method can be well used in induction or in recovery to monitor real-time anesthesia changes. A single supramaximal stimulation is applied during 200 micro sec at: 1Hz (every 1 sec) and 0.1Hz (every 10 sec).
    - DBS (double burst stimulation): A new pattern of nerve stimulation to detect residual neuromuscular block manually. The response to this pattern of stimulation consists of two single separated muscle contractions, of which the second is less strong than the first during non-depolarizing neuromuscular blockade. The ability to identify fade manually at different train-of-four (TOF) ratios was compared in four DBS patterns in which different numbers of impulses in the individual bursts were combined.
    - PTC (post-tetanic count): This mode allows for more sufficient, continuous neuromuscular monitoring even in the state of deep muscle relaxation. Also, our Life Scope G9 automatically changes the mode from TOF to PTC (post-tetanic count) to monitor deeper muscle relaxation when patient TOF ratio goes to zero.
    - TET (tetanic stimulation): Tetanic stimulation is used in medicine to detect a non-depolarising block or a depolarising block on the neuromuscular junction.
