10.6 CHANNELLING EFFECT
In procedures where high-frequency current might flow through body parts with a small
transverse diameter or through other pedicles (e.g. ovary-Fallopian tube, testes,
gallbladder) there is a risk that the high-frequency current will cumulate in the narrowest
place. This may lead to unwanted heat generation (burns) and tissue necrosis in a spot
that is distant from the operating field. This phenomenon is known as the channelling
effect. The bipolar mode should be employed in such cases, since it minimizes the risk of
coagulation in unwanted locations.
Examples of locations where the channelling effect may occur:
Application site of monopolar
high-frequency current
Place where the high-frequency
current cumulates. Risk of burns
10.7 The output power setting should not be greater than necessary for performing a
given procedure.
10.8 An error of an electrosurgical device may result in undesirable increase in output
power and inadvertent damaging of patient's tissues. A yearly technical inspection of the
device in an authorized manufacturer's service centre shall minimize the risk of failure.
10.9. An evident drop in the output power, when 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 reduction in unit quality. This especially applies to
soft and bipolar coagulation. The active electrodes should be cleaned of residual tissues
during the procedures.
