Tissue effect

The type of tissue effect (eg, cutting, coagulation) is dependent on many factors, such as voltage, power, tissue resistance, current density, and electrosurgical waveform properties. The primary user-adjustable variable of essentially all ESUs until recent years was power output. The endoscopist would select a desired power setting and the ESU would deliver that power output, regardless of the surrounding tissue properties. During electrosurgery (eg, during polypectomy), tissue resistance is initially low and current flows easily into the tissue. However, progressive tissue desiccation increases the resistance (impedance)
to current flow. The generator attempts to maintain constant power output, but as tissue changes occur, there can be significant fluctuations in voltage. In recent years, advances have led to ESU circuitry capable of monitoring for changes in voltage that occur during the delivery of electrosurgical energy. These ESUs are capable of keeping voltage constant while power fluctuates to the lowest effective output, based on impedance within the circuit. This facilitates reproducible and consistent target tissue effects during electrosurgery.
