The Surgical Diathermy: Principles of Operation and Safe Use

Abstract

An understanding of the principles of operation and hazards of the surgical diathermy is necessary for the safety of the anaesthetized patient. The surgical diathermy performs its function by the application of high density radio frequency current which can be used to cut or coagulate tissue. Its improper lIse can result in electrical burns and even electrocution. The principles underlying its safe llse are outlined, and detailed recommendations are made to enSllre the patient's safety.

A comparative study of scalpel and surgical diathermy incision in elective operations of head and neck cancer

“…[19] Inadvertent burns may occur at the surgical site or at the site of placement of the dispersive electrode (grounding pad). [20][21][22] Electrosurgery related fire hazards have also been reported in the literature before the advent of non-explosive anesthetic agents. Following the introduction of halothane, electrosurgery has been widely used as has been described in thyroidectomy by head and neck surgeons [23] and blepharoplasty by plastic surgeons.…”

The Effect of Electrocoagulation on the Sinusoids in the Human Penis

“…It is rational to apply a Bovie whenever a bleeder is encountered according to our surgical training background (Watson and Loughman, 1978; Polk et al, 2001). However, in our analysis, this principle may require alteration if the organ is related to erectile tissues of the penis.…”

“…The aim of the pad application is to provide a low resistance and low current density. 38 Foil sheets of silver, copper, aluminum, and stainless steel are used as conductors in grounding pads. Because good conductors, like these metals, permit electrons to move easily through them, the current will preferentially be attracted to the grounding pad.…”
