“…Heat generation and thermal tissue damage are the cause of the obtained electrosurgery effect. The only variable that determines the ultimate current effect on the tissue is the depth of affected tissue and the rate of heating (Taheri et al, 2014;Haneke, 2015).…”

“…Some electro-surgical biophysical mechanisms are more or less studied, but the full effect of these technologies on different tissues is unknown. It has been investigated that during their exposure to tissues, the temperature increases locally, causing coagulation and apoptosis of proteins (Tobias & Johnston, 2012;Haneke, 2015), but there is a lack of data on the extent and depth of these thermal damages. It is also not known whether these effects on the different tissues of the body are the same and how they affect the regeneration processes.…”

“…Tissue incision by electrocoagulator is achieved by heating the tissue to the boiling point, causes a rapid explosion of water in the cell and protein denaturation, which leads to cutting the tissue (Wall & Gertners, 2008;Taheri et al, 2014). Thermal effect of electrocoagulator on the tissue depends on the energy level, the duration of application and the biological properties of the tissues (Beriat et al, 2012;Tobias & Johnston, 2012;Haneke, 2015).…”

“…During exposure to radio frequency device, the tissue becomes an object which radio waves flow through. By using radio frequency current, the temperature of the internal structures of the cells increases, intracellular fluid is lost and protein denaturation occurs (Tobias & Johnston, 2012;Haneke, 2015) The narrow range of radio frequency waves ensures reduced heating of surrounding tissues (Vogt, 2008;Taheri et al, 2014). Radio waves during surgical manipulation can almost completely prevent thermal damage (Haneke, 2015).…”

The purpose of using electrosurgical devices in veterinary practice is to reduce bleeding during the cut increasing temperature locally, causing coagulation and apoptosis of proteins. There is a lack of data on the extent and depth of these thermal damages and whether these effects on the different tissues are the same. Because of that, the aim of this study was to investigate which of the different electrosurgical devices causes highest heating effect on the skin tissue of rabbits (Oryctolagus cuniculus). The research was carried out at the Latvia University of Life Sciences and Technologies, Faculty of Veterinary Medicine. It included 50 rabbits, on average 2 years old, clinically healthy, with similar weight and condition. We formed five experimental groups: skin tissue cut with CO 2 laser (n=10), an electrocoagulator (n=10), a tissue welding device (n=10), a radiofrequency apparatus (n=10) and a scalpel as control group (n=10). In order to evaluate the thermal effects of electrosurgical instruments on tissues, we performed contactless thermography. There were taken 3 images for each animal, totally 150 skin thermo-gramms. From the obtained results we conclude that the most pronounced thermal effect on rabbit's skin was caused with laser and an electrocoagulator. All electrosurgical devices caused a significantly higher (p<0.01) increase in skin temperature compared to a surgical scalpel at the moment of tissue incision. During the study, it was found that the gentlest electrosurgical devices used on rabbit skin tissue was a radiofrequency device.

During splenic surgery, it is important to control blood loss and the potential risk of cardiac arrhythmia. The best way to prevent complications from surgery is to use the appropriate surgical devices; however, there is no guideline for the use of specific surgical devices for spleen incision. Therefore, the aim of this research was to compare the interactions of various surgical devices with spleen tissue, their cardiorespiratory effects during incision, and subsequent spleen surgical wound healing. A total of 75 rabbits were included in the study. CO2 laser (n = 15), radiofrequency device (n = 15), electrocoagulator (n = 15), tissue-welding device (n = 15), and scalpel (n = 15) were used to make incisions in rabbits' spleens. Spleen biopsies of the incision area were taken from each animal at the day 0, 7, and 14 after surgery. Contactless thermography was performed during surgery. Suturing was not used after incision with the tissue-welding device, but incisions made by other surgical devices were sutured. The results showed that the width of spleen necrosis differed significantly between the various surgical devices used on spleen tissues. There was a positive, strong, and linear association between necrosis width and the tissue temperature of cutting edges. Significant increases in the heart rate were observed during spleen surgery performed with laser, scalpel, and radiofrequency devices. In conclusion, the tissue-welding device confers a significant advantage in spleen surgery, as there is neither a need for sutures nor a significant deviation in the heart rate.
