Examples of locations where the channelling effect may occur:
10.7
The output power setting should not be greater than necessary for performing a given procedure.
10.8
An error of an electrosurgical unit may result in an undesirable increase of output power and inadvertent
damage to the patient's tissues. An annual technical inspection of the unit in an authorised manufacturer's
service centre will minimise the risk of failure.
10.9
An evident drop in the output power, when the settings are normal, can mean:
- incorrect application of the neutral (silicone) electrode,
- damaged cables,
- residues of coagulated tissue on the instrument.
Check for the above situations before increasing the power.
10.10
Unclean electrodes can cause a deterioration of the quality of the unit. This especially applies to soft
and bipolar coagulation. The active electrodes should be cleaned of residual tissues during the procedures.
10.11
During the operations performed in the region of the thorax or the head it is recommended that the use
of flammable anesthetics or oxidizing gases, such as nitrous oxide (N
2
O) and oxygen, should be avoided,
unless those agents are sucked away.
10.12
Use non-flammable disinfectants. Otherwise, they should be left to evaporate before the procedure.
There is also a risk of pouring those agents under the body or into a body cavity. Should this happen, such
flooded areas should be dried. A flammable agent can be set on fire by a spark occurring during normal unit
operation.
10.13
Sparks at the active electrode pose the risk of setting bandages and metabolic gases on fire.
10.14
During a procedure, there is also a risk that a heart pacemaker can be damaged or its function can be
interfered with during a procedure. In these cases, the bipolar technique should be used. If monopolar modes
are necessary, the neutral electrode should be placed as far as possible from the pacemaker. The active
electrode should not be used near the pacemaker. It is recommended that the current should be applied for a
short time at short time intervals. Before using electrosurgery, consult an authorised representative of the
heart pacemaker and a cardiac surgeon. Check the pacemaker thoroughly after the procedure. It is not
permitted to use electrosurgery systems on patients with heart pacemakers under outpatient clinic conditions.
