High-frequency surgical device GN300
Note
The monitoring of the contact quality between the neutral electrode and
the patient via the contact quality monitor is only possible if a divided neu-
tral electrode is used.
To avoid a temperature rise at the exit point of the current, the following
conditions must be ensured:
■
Contact surfaces of adequate size between neutral electrodes and the
body.
■
High electrical conductivity between the neutral electrodes and the
body.
To rule out the possibility of burns from neutral electrodes, be sure to
undertake the following:
►
Select areas of application for neutral electrodes that result in the
shortest possible electrical pathways between active and neutral elec-
trodes; and that are longitudinal or diagonal to the body (since muscles
with the same orientation as the fibrilla are more conductive).
►
In operations in the thorax area, make certain the path of the current
does not run across the chest and does not run through the heart.
►
Depending on the operation field, apply the neutral electrode at the
nearest upper arm or thigh, if possible.
►
When applying disposable self-adhesive neutral electrodes, follow the
instructions of the supplier with regard to the area of application.
►
Ensure that the application area is free of both scar tissue and bony
outgrowth.
►
Make sure that the electronic pathway does not intersect any implants
(e.g. bone nails, bone plates, endoprostheses).
►
Prior to applying the neutral electrode:
– Shave the site for the neutral electrode, if hair is present.
– Clean the area to be operated on (do not use alcohol, as it dries out
the skin and increases contact resistance).
– In patients with poor circulation, massage or brush the application
area.
►
Apply neutral electrodes systematically over the entire surface of the
designated application area. Secure reusable neutral electrodes with
bandage, or other suitable material, thereby ensuring that the elec-
trodes do not come loose if the patient moves. At the same time,
ensure that such measures do not constrict blood flow (risk of necro-
ses).
►
Apply type 3 reusable neutral electrodes in such a way that their black,
conductive surfaces lie on the patient and their blue surfaces face
away from the patient's body.
►
To forestall raised contact resistance caused by epidermal dehydration
arising from the use of damp cloths or electrode paste: do not under
any circumstances use damp cloths or electrode paste.
►
To prevent burns arising from short bursts of high electric current:
Ensure that no fluids (e.g. irrigation fluids, disinfectants, blood, urine)
get between the patient and the neutral electrode.

►
To prevent fluid buildup, reduced blood flow or perfusion, pressure
necroses, displacement of the neutral electrodes and contact resis-
tance: Do not lay neutral electrodes under patient's buttocks or back.
►
Check to make sure that the electrical pathway of the HF device does
not intersect any EEG electrodes.
