early detection of technical faults which could endanger the

patient and place the success of the anaesthesia in jeopardy.

Performing PNS with the Stimuplex

HNS 11 and the Stimuplex

or Contiplex

needles

1. Check the Stimuplex

HNS 11.

2. Check the skin electrode (ECG adhesive electrode) (the conduc-

tive gel must not have dried) and apply it to a degreased area of

skin which is not in the distribution area of the nerve to be

blocked.

3. Carry out patient positioning, skin disinfection, and if neces-

sary, local infiltration of the needle puncture site.

4. Connect the electrode cables to the stimulation needle (nega-

tive) and skin electrode (positive), switch on the Stimuplex

HNS

11 and set the mA controller current (mA

) to zero.

After the automatic self-test of the stimulator, the

▲

symbol

appears in the display in time with the stimulation pulse to

indicate that it is ready to operate.

Caution! A change to the stored parameters can only be made

when the LEDs are lit. By pressing any button the LEDs will light up

and indicate the value stored. To change press the appropriate

button.

5. Select pulse width (0.1 ms, 0.3 ms or 1.0 ms).

6. Select pulse frequency (1 Hz or 2 Hz).

7. Select amplitude range (1 mA max or 5 mA max.).

8. Advance the Stimuplex

or Contiplex

needle through the skin

and the subcutaneous tissue towards the nerve to be blocked.

Set a current of approx. 0.30 mA (set value mA

) - the orange

LED above the display flashes in time with the stimulation, the

display shows a

next to the

▲

and a tick signals that current

is flowing in the tissue.

Then switch to actual current flowing value indicator (mA

)

and check that the actual value corresponds to the set value

(see p. 12 - Technical data, measuring tolerance).
