ELECTROSURGICAL UNIT
3.0 SAFETY NOTES & ALARMS
Attention to the following points is necessary
in order to reduce the risk of accidental burns
during the use of this electrosurgical unit. Other
safety notes and warnings are also given within
the text of this manual and these should be
noted before using this electrosurgical unit.
DO:
♦
Use only Eschmann accessories, in particular active
and plate electrodes and cables which should
preferably be no more than 3 metres in length. All
Eschmann accessories are rated above the
corresponding maximum peak output voltage of this
electrosurgical unit (see graphs in section 5). For
reference Eschmann accessories can be used safely
at the following h.f. peak voltages:
Bipolar active - 400 V peak
Monopolar active - 4000 V peak
Monopolar plate electrode - 2250 V peak
♦
Use bipolar techniques in preference to monopolar,
whenever possible. For surgical procedures on parts
of the body having a relatively small cross-sectional
area, the use of bipolar techniques may be desirable
to avoid unwanted coagulation.
♦
Seek approved qualified advice (e.g. cardiology
department) before using this electrosurgical unit on
patients with implanted pacemakers or other active
implants to avoid interference or damage to the implant.
Monitor such patients carefully.
♦
Set power output controls to the minimum setting
before use and select the minimum power setting to
achieve the desired effect.
♦
Check all cables and accessories routinely before
use. In particular, electrode cables and endoscopically
used accessories for possible damage to the insulation.
♦
Ensure the entire area of the plate electrode is reliably
attached to the patient’s body and as close to the
operating field as possible.
♦
Store temporarily unused active electrodes such that
they are isolated from the patient [e.g. use a quiver
(REF 83-186-38) to hold active accessories when not
in use].
DO NOT:
♦
Do not use uninsulated forceps, monopolar or bipolar.
♦
Do not place monitoring electrodes close to the
operating site. When high frequency surgical
equipment (i.e. electrosurgical equip-ment) and
physiological monitoring equip-ment are used
simultaneously on the same patient, any monitoring
electrodes should be placed as far as possible from
the surgical electrodes. Needle monitoring electrodes
are not recommended. In all cases, monitoring
systems incorporating high frequency current limiting
devices are recommended.
♦
Do not allow active cables to drape across or contact
the patient's body or contact the cables or leads of
other equipment.
♦
Do not use flammable anaesthetics, flammable
solvents or oxidizing gases such as nitrous oxide
(N
2
O) or oxygen if the surgical procedure is carried
out in the region of the thorax or head, unless these
agents are sucked away.
♦
Do not allow the patient's body to touch conductive
objects. The patient should not come into contact with
metal parts which are earthed or which have an
appreciable capacitance to earth, e.g. operation table,
supports, etc. The use of antistatic sheeting is
recommended for this purpose.
♦
Do not use hook type active cables (with or without
adapters designed for use with hook type cables) use
4 mm or 8 mm plug type active cables.
♦
Do not reuse disposable plate electrodes.
♦
Do not rely solely on surgical gloves to provide
insulation.
♦
Do not allow ‘skin-to-skin’ contact (e.g. between the
arms and body of the patient), this can be avoided, for
example by the insertion of adequate dry gauze.
