Patient Return Electrodes
Laparoscopic Procedures
Warning
To avoid patient burns, ensure that the patient return electrode firmly contacts the
skin. Always check the patient return electrode periodically after the patient is
repositioned and during procedures involving long periods of activation.
Warning
For laparoscopic procedures be alert to these potential hazards:
• Laparoscopic surgery may result in gas embolism due to insufflation of gas into
the abdomen.
• The electrode tip may remain hot enough to cause burns after the
electrosurgical current is deactivated.
• Inadvertent activation or movement of the activated electrode outside of the
field of vision may result in injury to the patient.
• Localized burns to the patient or physician may result from electrical currents
carried through conductive objects (such as cannulas or scopes). Electrical
current may be generated in conductive objects by direct contact with the active
electrode, or by the active accessory (electrode or cable) being in close
proximity to the conductive object.
• Do not use hybrid trocars that are comprised of both metal and plastic
components. For the operative channel, use all metal or all plastic systems. At
no time should electrical energy pass through hybrid systems. Capacitive
coupling of RF current may cause unintended burns.
• When using laparoscopic instrumentation with metal cannulas, the potential
exists for abdominal wall burns to occur due to direct electrode contact with or
capacitive coupling of RF current. This is most likely to occur in instances
where the electrosurgical generator is activated for extended periods at high
power levels and induced high current levels in the cannula.
• Ensure that the insulation of single use and reusable laparoscopic
instrumentation is intact and uncompromised. Compromised insulation may
lead to inadvertent metal to metal sparking and neuromuscular stimulation
and/or inadvertent sparking to adjacent tissue.
• Do not activate electrodes while in contact with other instruments as
unintended tissue injury may occur.
• Do not activate the generator in an open circuit condition. Activate the
generator only when the active electrode is near or in direct contact with the
target tissue to lessen the possibility of creating unintended burns.
• Use the lowest power setting that achieves the desired surgical effect and use a
low voltage waveform (cut mode) to lessen the potential for the creation of
capacitive currents.
• Carefully insert and withdraw active electrodes from cannulas to avoid possible
damage to the devices and/or injury to the patient.
