Electrosurgery Flashcards
T/F patients should avoid contact with grounded metal objects to minimise the risk of electric burns
T
Flammable topical preparations should not be used prior to electrosurgery due to propensity for ignition and char formation
T
Aluminium chloride should be used prior to electrosurgery
False , this is flammable
Which types of electrosurgery are high voltage
Electrodessication and Electrofulguration
(DF)
These are also mono terminal
Which electrosurgery are biterminal
Electrocoagulation
Electrosection with coagulation
Electrosection
Electrodessication and electrofulguration are best suited for destroying relatively superficial avascular lesions. Eg. Verruca and seb K
True
Electrocoagulation is the preferred method for superficial lesion destruction
False, NOT the preferred method
With electrosection, the majority of energy dissipates during tissue vaporisation and minimal collateral damage occurs
T
Electrocautery uses low-voltage, high amp direct OR alternating current to cause tissue dessication, coagulation or necrosis by direct heat transference to tissue
True
Regarding electrolysis, hair follicles in TELOGEN are not destroyed as effectively
F, anagen
Is subcutaneous fat is reached during curette and cautery, need to abandon procedure
T, for excision p143
Risks of electrosurgery
Electrical burns Electrical shocks Infection transmission Eye injury Implanted device malfunction P.145
Surgical smoke contains 5% particulate matter - including some known carcinogens
T
No risk of corneal injury with electrosurgery in the periorbital region
F. - sparks can arc towards the globe and cause corneal damage and scarring
Risk of arrhythmia increases with myocardial anoxia, electrolyte imbalance and drug toxicity
T
