“…Today, electrosurgical units are an indispensable part of most operations [1]. They have been in use for about 90 years and have a direct impact on clinical results [1][2][3][4]. By allowing for hemostasis during surgery, electrosurgical units give the surgical team better visual access to the area under surgery [2], reduce the need for blood transfusion, curtail the length of anesthesia and surgery, and prevent local hematomas after surgery [2][3][4][5][6].…”

Background: An electrosurgical unit is one of the most essential pieces of equipment in operating rooms. Over 80% of operations today make use of electrosurgical units. Training operating room nurses in correct application of electrosurgical units and evaluation of their application play a key role in making optimal use of the units and extending their lifetime, reducing occupational hazards for surgical teams, and enhancing the safety of patients. The present study aims to investigate the effects of an educational intervention on operating room nurses' application of electrosurgical units. Methods: The present study is a quasi-experimental work of research conducted in all the operating rooms of the hospitals located in Shiraz, Iran. Data were collected from 200 observations of 200 surgeries (100 before intervention and 100 after). The content of education was derived from a literature review and standard guidelines and was presented as a poster in the operating rooms. The data collection instruments consisted of a Demographic Information Questionnaire, a surgery checklist, and the checklist for operating room Nurses' application of electrosurgical units. Data were collected once before the intervention and then again one month after the intervention. The collected data were analyzed using the descriptive statistics of chi-square test and paired t-test at a significance level of 0.05 in SPSS v. 18.Results: The average age of the participating nurses was 31.540±6.772 years. The majority of the participants were female. The results showed a statistically significant difference between the means and standard deviations of the nurses' application of electrosurgical units scores before (18.330±2.666) and after (20.820±3.400) intervention. Conclusion: Introducing operating room nurses to the standard guidelines for application of electrosurgical units can improve the quality of services provided by the nurses, increase the safety of patients, and reduce occupational hazards. Thus, to improve operating room nurses' professional performance in application of electrosurgical units, medical managers and policy-makers should attach more importance to on-the-job training programs.

“…Electrosurgical units (ESUs) are among the most frequently-used devices in surgeries since they conduct electricity through a surgical tool to the patient's body (1)(2)(3)(4). By creating hemostasis during surgery, ESUs enable the surgical team to make a surgical incision without causing bleeding and, thus, have a better view of the area under operation (1).…”

Application of Electrosurgical Units by Operating Room Personnel: Development and Psychometric Testing of an Instrument

Background: Today, electrosurgical units are an indispensable part of surgeries. Yet, inappropriate application of this equipment can result in dire consequences for both the patient and the surgical team. Objectives: The present study aimed at developing the psychometric properties of a checklist to evaluate the application of electrosurgery units by operating room personnel. Methods: The present methodological study was performed in two stages: first, the items of the checklist were developed based on a literature review and search in relevant websites; and second, the psychometric properties of the checklist were measured using the methods to evaluate face, content, and construct validities. The reliability was measured through an assessment of the internal consistency of the checklist, based on the degree of inter-rater agreement. To assess construct validity, the researchers compared known groups; 40 surgeries were observed in two university hospitals in the intervention and control groups. Results: The content validity index (CVI) of all the items was over 0.79. The average CVI (S-CVI/Ave) of the checklist with 32 items was 0.97. The results of the Wilcoxon test showed that the posttest performance scores of the personnel in the intervention group were significantly higher than their pretest scores (P value = 0.005). The internal consistency (the Kuder-Richardson coefficient) of the checklist was 0.66. Conclusions: Due to the great importance of appropriate application of electrosurgery units, a reliable instrument is needed to assess personnel's performance in this area. The results of the current study showed that the present instrument is sufficiently valid and reliable to evaluate the application of electrosurgical units by the operating room personnel.

“…Some experimental studies have compared the impact of sealants with other coagulation techniques and have demonstrated that sealants reduce necrosis 9 , fluid collection, and abscess formation 10 , and increase regeneration of the resection plane after liver resection 11 . However, to our knowledge, the postoperative histopathological effects of different sealant materials on the liver surface after hepatectomy have not been compared in detail so far.…”

The present study aimed to determine the impact of different sealant materials on histopathological changes to the liver surface after liver resection. Thirty-six landrace pigs underwent left anatomical hemihepatectomy and were assigned to a histopathological control group (HPC, n = 9) with no bleeding control, a clinically simulated control group (CSC, n = 9) with no sealant but bipolar cauterization and oversewing of the liver surface, and two treatment groups (n = 9 each) with a collagen-based sealant (CBS) or a fibrinogen-based sealant (FBS) on resection surface. After postoperative day 6, tissue samples were histologically examined. There were no significant differences in preoperative parameters between the groups. Fibrin production was higher in sealant groups compared with the HPC and CSC groups (both p < 0.001). Hepatocellular regeneration in sealant groups was higher than in both control groups. A significantly higher regeneration was seen in the FBS group. Use of sealants increased the degree of fibrin exudation at the resection plane. Increased hepatocellular necrosis was seen in the CBS group compared with the FBS group. The posthepatectomy hepatocellular regeneration rate was higher in the FBS group compared with the CBS group. Randomized studies are needed to assess the impact of sealants on posthepatectomy liver regeneration in the clinical setting.

Comparison between electrocautery and fibrin selant after hepatectomy in rats

Abstract: hemostasis achieved by the groups was similar; however, the use of electrocautery was associated with infections, adhesions at higher grades and elevated liver enzymes.
