Document Summary

Monopolar vs bipolar: monopolar: active electrode at surgical site. Current flows through the body: bipolar: active and return electrodes within the instrument. Fardari effect: high frequency does not activate excitable tissue such as muscle & nerves. Cellular cytoplasm contains electrically charged particles or ions in the form of atoms and molecules. Cations are small, positively charged atoms like sodium, potassium, and calcium, while the anions include atoms such as chlorine as well as large, negatively charged protein molecules. Electrosurgery vs electrocautery: electrocautery: heat up an element and transfer the heat to a patient. (transfer of heat. Carbon serves an insulator and will impede a lot of the resistance flow. Dispersion pad placement (return electrode: we put this on the chickens back. In humans, you want to put it on a well vascularized muscular wall. If you lose contact with the dispersio(cid:374) pad, there is(cid:374)"t as (cid:373)uch curre(cid:374)t.
