Laparoscopic Procedures
Warning
For laparoscopic procedures, be alert to these potential hazards:
• Laparoscopic surgery may result in gas embolism due to insufflation of gas in
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 through direct contact with the
active electrode, or by the active instrument (electrode or cable) being in close
proximity to the conductive object.
• Do not use hybrid trocars that have a non-conductive locking anchor placed
over a conductive sleeve. 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 or
capacitive coupling of RF current. This is most likely to occur in instances
where the energy platform is activated for extended periods at high power
levels inducing 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 energy platform in an open circuit condition. To reduce the
chances of unintended burns, activate the energy platform only when the active
electrode is near or touching the target tissue.
• Use the lowest power setting that achieves the desired surgical effect and use
a low voltage waveform (Pure Cut, Blend, or Valleylab mode) to lessen the
potential for the creation of capacitive currents.
• Carefully insert and withdraw active electrodes from cannulas to avoid possible
injury to the patient or damage to the devices.
Valleylab recommends against the use of laparoscopic surgery on pregnant
patients.
