Understanding the Relationship between
Surgical Gloves and Electrosurgery
Current: Refers to the flow of electric charge. The most familiar artificial
form of electric current is the flow of conduction electrons in metal wires; i.e.,
wires within electrical equipment. Electrical current can be alternating current
(AC), which means that the direction of electrons alternate or switch, or direct
current (DC), in which the flow of electrical current (electrons) is in one direction
only.
Capacitive Coupling: The condition that occurs when alternating (AC) electrical
current is transferred from one conductor (an electrode), across intact insulation,
into adjacent conductive materials (tissue or skin) or another metal surgical instrument.
Capacitance is stored electrical charge.
Dielectric Breakdown: Breakdown of a nonconductive material (e.g., a rubber
glove), which may be caused by highvoltage output from the electrical generator.
Electrosurgery: The passage of Radio Frequency (RF) or high-frequency electrical
current through tissue to create a desired clinical effect on the tissue. RF current
is measured in cycles per second.
Resistance/Impedance: The lack of conductivity or the opposition to the flow
of electrical current. The terms are used interchangeably. Resistance/impedance
is measured in ohms.
