The Microstim DB3 is the latest addition to the Microstim range, which has been popular with human medical anaesthetists worldwide since 1985 and has served extremely well, being low cost, easy to operate and reliable in use. It is now available with clips to extend these benefits to veterinary anaesthetists. This allows easy attachment via needles to stimulate facial, median, ulna or tibia nerves.
This Nerve Stimulator has four settings:
A) Train of Four
B) Double Burst Stimulation
C) Post Tetanic Count
D) Continuous 1 Hz
We are often asked why the Microstim does not have a display to show the delivered current - this is why:
1. The current required for supramaximal stimulation varies considerably between patients. The best way to establish supramaximal stimulation is to gradually increase the stimulus current until the response is elicited.
2. Because the Microstim is a constant current stimulator, it is not subject to current-reduction as a result of high skin impedance. A non-constant current stimulator needs a display to indicate the delivered current.
3. A numerical display can give the erroneous impression to the inexperienced user that the display somehow indicates the magnitude of the muscle response.
