In the general election, facing Democratic nominee, Senator Barack Obama of Illinois, McCain was trailing during most of the season, only gaining a lead in national polls for a period after the Palin announcement and the 2008 Republican National Convention.
monopolar electrocautery (unipolar electrocautery) an electrocautery in which current is applied through a handheld active electrode and travels back to the generator through an inactive electrode attached to the patient (the grounding pad), so that the patient is part of the electrical circuit.Also called unipolar electrocautery.n electrocautery in which current is applied through a handheld active electrode and travels back to the generator through an inactive electrode attached to the patient (the grounding pad), so that the patient is part of the electrical circuit. Also called unipolar electrocautery.
It is important to use a generator that can alternately provide both bipolar power for cautery with minimal collateral injury with the use of a monopolar power for cutting, cutting/cautery, and cautery. This combined used of types of energy increases the efficiency of doing general surgery.adiofrequency. An energy source (Ellman International) using high-frequency electrical current that can be used as either bipolar or monopolar mode (4.0 mHz). The zone of injury is comparable or less than a carbon dioxide laser when both are used in appropriate fashion for traditional surgery.
