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.
The return electrode pad is attached to the patient, so the electrical current flows from the generator to the electrode through the target tissue, to the patient return pad and back to the generator. Monopolar electrosurgery is the most commonly used because of its versatility and effectiveness.onopolar electrosurgery can be used for several modalities including cut, blend, desiccation, and fulguration. Using a pencil instrument, the active electrode is placed in the entry site and can be used to cut tissue and coagulate bleeding.
