Before applying the neutral electrode
X Shave the area where the neutral electrode will be applied.
X Clean the application site, but do not use any alcohol, as it dries
out the skin and increases the transition resistance.
X
If the patient has poor circulation, massage or brush the application
site.
X Apply the neutral electrode using the entire contact surface. Secure
reusable neutral electrodes with rubber bands or elastic ties so that
they do not loosen or fall off when the patient moves. Ensure that
the patient's circulation is not impaired (risk of necrosis).
X Never use wet towels or electropastes.
X Ensure that no liquids (e.g. cleaning fluids, disinfectants, blood,
urine) get between the patient and the neutral electrode.
X
Do not place the neutral electrode under the patient's buttocks or
back.
X Ensure that there are no EKG electrodes in the current path of the
HF device.
Use of a solid neutral electrode
X When applying the solid neutral electrode, ensure that the HF
current flows back to the longest edge so that no excessive current
density develops on the short edge.
X
Check the solid neutral electrode during the surgery.
Use of a split neutral electrode
X Apply the split neutral electrode correctly and without any additional
objects, as the HF device does not recognize the bridging of the
section surfaces by other objects.
X
Ensure that when you apply the split neutral electrode, the HF
current flows evenly back to both surfaces, so that no excessive
increase in the current density develops beneath a surface or an
edge.
