Coagulation Function
Listed below are general precautions to be followed when using the Coagulation function:
• To ensure safe operation of the coagulation function, only approved cables
and accessories must be used (See your Alcon representative). Coagulation
performance can be guaranteed only when using Alcon components or Alcon-
endorsed components.
• To reduce the risk of accidental burns, caution should always be taken when
operating high-frequency surgical equipment.
• Interference produced by the operation of high-frequency surgical equipment may
adversely inuence the operation of other electronic equipment.
• Accessories should be checked regularly; electrode cables should particularly be
checked for possible damage to the insulation.
• Operation of the coagulation step is limited to extraocular uses only.
• The lowest power level in coagulation step should always be selected for the
intended purpose.
• Skin-to-skin contact (for example between the arms and body of the patient)
should be avoided, for example by insertion of dry gauze.
• When HF (high frequency) surgical equipment and physiological monitoring
equipment 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.
• The cables to the surgical electrodes should be positioned in such a way that
contact with the patient or other leads is avoided.
• Temporarily unused active electrodes should be stored so that they are isolated
from the patient.
• The use of ammable anaesthetics or oxidizing gases such as nitrous oxide (N
2
O)
and oxygen should be avoided if a surgical procedure is carried out in the region of
the thorax or the head, unless these agents are sucked away.
• Non-ammable agents should be used for cleaning and disinfection wherever possible.
• Flammable agents used for cleaning or disinfecting, or as solvents of adhesives,
should be allowed to evaporate before the application of HF surgery. Some
materials, for example cotton, wool and gauze, when saturated with oxygen may
be ignited by sparks produced in normal use of the HF surgical equipment.
• Accessories should have a rated voltage equal to or greater than the maximum
coagulation output voltage.
WARNINGS!
Do not use the coagulation function on patients with pacemakers or implanted
debrillatory devices. If electrosurgery is used on patients with implanted cardiac
pacemakers or debrillatory devices or pacemaker electrodes, be aware that
irreparable damage to the pacemaker or debrillatory device and its function
may occur and lead to ventricular brillation. Please check with the pacemaker
or debrillatory device manufacturers for their recommendations.
Failure of the HF surgical equipment (coagulation circuitry) could result in an
unintended increase of output power.
