Summary
DescriptionAcceleromyography monitoring with preload hand adapter.jpg |
English: Acceleromyography is a form of quantitative neuromuscular monitoring and may be used to assess the effects of muscle relaxants when used as part of general anaesthesia. The black negative stimulating electrode is placed over the distal part of the ulnar nerve and the white positive electrode 3 cm proximally over the same nerve. A piezoelectric crystal is placed on the thumb and acceleration of the crystal caused by contraction of the muscle when the nerve is stimulated generates a voltage that is proportional to the force of the muscle contraction. Force = mass X acceleration.Quantitative neuromuscular monitors can assess the depth of neuromuscular blockade and exclude the residual effects of muscle relaxants when used in combination with general anaesthesia.
Français : L'accéléromyographie est une forme de surveillance neuromusculaire quantitative et peut être utilisée pour évaluer les effets des relaxants musculaires dans le cadre d'une anesthésie générale. L'électrode de stimulation négative noire est placée sur la partie distale du nerf cubital et l'électrode positive rouge à 3 cm proximalement sur le même nerf. Un cristal piézoélectrique est placé sur le pouce et l'accélération du cristal provoquée par la contraction du muscle lorsque le nerf est stimulé génère une tension proportionnelle à la force de la contraction musculaire. Force = accélération de masse X. Des moniteurs neuromusculaires quantitatifs peuvent évaluer la profondeur du blocage neuromusculaire et exclure les effets résiduels des relaxants musculaires utilisés en association avec une anesthésie générale.

L'elettrodo di stimolazione negativo nero è posto sopra la parte distale del nervo ulnare e l'elettrodo rosso positivo 3 cm prossimalmente sullo stesso nervo. Un cristallo piezoelettrico è posto sul pollice e l'accelerazione del cristallo causata dalla contrazione del muscolo quando il nervo viene stimolato genera una tensione proporzionale alla forza della contrazione muscolare. Forza = accelerazione di massa X. I monitor neuromuscolari quantitativi possono valutare la profondità del blocco neuromuscolare ed escludere gli effetti residui dei rilassanti muscolari se usati in combinazione con l'anestesia generale.

Deutsch: Die Acceleromyographie ist eine Form der quantitativen neuromuskulären Überwachung und kann verwendet werden, um die Auswirkungen von Muskelrelaxanzien zu beurteilen, wenn sie als Teil einer Allgemeinanästhesie verwendet werden. Die schwarze negative Stimulationselektrode wird über dem distalen Teil des N. ulnaris und die rote positive Elektrode 3 cm proximal über demselben Nerv angeordnet. Ein piezoelektrischer Kristall wird auf dem Daumen platziert und die Beschleunigung des Kristalls, die durch die Kontraktion des Muskels verursacht wird, wenn der Nerv stimuliert wird, erzeugt eine Spannung, die proportional zur Kraft der Muskelkontraktion ist. Kraft = Beschleunigung der Masse X. Quantitative neuromuskuläre Monitore können die Tiefe der neuromuskulären Blockade beurteilen und die Resteffekte von Muskelrelaxanzien ausschließen, wenn sie in Kombination mit einer Vollnarkose verwendet werden. |
