[PMID: 38959788 DOI: 10.1016/j.ecoenv.2024.116671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 06/16/2024] [Accepted: 06/28/2024] [Indexed: 07/05/2024]
Abstract
BACKGROUND With the advancement of medical technology, tools such as electrosurgical equipment, laser knives, and ultrasonic scalpels have made modern medical procedures more convenient and effective. However, the generation of surgical smoke during these procedures poses significant health risks to medical personnel. Despite this, only a few studies have examined the literature systematically in this area. By analyzing bibliometric data on surgical smoke, we can gain insights into current research hotspots and forecast future trends. METHODS This study included literature related to surgical smoke from the Web of Science and China National Knowledge Infrastructure (CNKI) databases, covering the period from 2000 to 2024. We used VOSviewer, CiteSpace, and BioBERT to visualize research trends and hotspots. RESULTS In the early stages of research, the focus was mainly on the composition, generation mechanisms, and susceptible populations related to surgical smoke. In recent years, with the development of laparoscopic surgery and the global COVID-19 pandemic, research interests have shifted towards occupational protection of healthcare workers and public health. Currently, the research in this field primarily explores the promoting effects of surgical smoke on conditions such as inflammation and tumors, as well as occupational protection and health education for healthcare workers. Disease research focuses heavily on Smoke Inhalation Injury, Infections, Neoplasms, Postoperative Complications, and Inflammation. CONCLUSION We explored future research directions in the field of surgical smoke using VOSviewer, CiteSpace, and BioBERT. Our findings indicate that current research focuses on investigating the promoting effects of surgical smoke on conditions such as inflammation and tumors, as well as on occupational protection and health education for healthcare workers. We summarized existing preventive measures, aiming to facilitate further research advancements and the translation of research outcomes into clinical results. These efforts provide new insights for advancing research in occupational protection of healthcare workers.

Abstract
Energy-based surgical instruments produce surgical smoke, which contains harmful byproducts, such as polycyclic aromatic hydrocarbons, volatile organic compounds, particulate matter, and viable microorganisms. The research setting has shifted from the laboratory to the operating room. However, significant heterogeneity in the methods of detection and placement of samplers, diversity in the tissue operated on, and types of surgeries tested has resulted in variability in detected levels and composition of surgical smoke. State regulation limiting surgical smoke exposure through local evacuators is expanding but has yet to reach the national regulatory level. However, most studies have not shown levels above standard established limits but relatively short bursts of high concentrations of these harmful by-products. This review highlights the limitations of the current research and unsupported conclusions while also suggesting further areas of interest that need more focus to improve Occupational Safety and Health Administration guidelines.

Abstract
In electro-surgery, surgical smoke was hazard to surgeons and patient in theatre. In order to institute effective countermeasures, quantifying of the effect of tip temperature of electro-surgical unit to surgical smoke distribution in theatre was studied. The relation of tip temperature to power of electro-surgical unit through in vitro cutting experiment. Based on experiment data, the mathematical model was established to simulate the electro-surgery in laminar operation room. As the power of electro-surgical knife increased, the knife tip temperature increased. Total content of (CO, CO2, CH4, NH3) in waste gas and net flow rate of waste gas at outlet increased with the rising temperature of knife tip and formation rate of condensed tar droplets and non-viable particles also increased. Based on simulation, it was found that The maximum height of surgical smoke rising right above the incision of electro-surgical unit was increased with rising temperature of electro-surgical knife tip. There was a spread route of dispersed surgical smoke near the walls of theatre through natural convection. The polynomial fitting relationship was derived. As the tip temperature of knife increased from 200 to 500°C, maximum ascending height of surgical smoke right above the incision position of electro-surgical unit increased from 1.1 m to 1.45 m. When the tip temperature of electro-knife was more 400°C, the CO content in the surgeon's operating zone was more than 200 ppm, which would cause the surgeon's HbCO level increased. As the patient's tissue in the wound during operation was open, when the electro-knife of more than 400°C, the content of condensed tar droplets and in-viable particle was higher than 20 g/m3 and 12 g/m3 in the zone around patient's wound of open tissue, which should be hazard to health of patient.

Abstract
The use of devices for tissue dissection and hemostasis during surgery is almost unavoidable. Electrically powered devices such as electrocautery, ultrasonic and laser units produce surgical smoke containing more than a thousand different products of combustion. These include large amounts of carcinogenic, mutagenic and potentially teratogenic noxae. The smoke contains particles that range widely in size, even as small as 0.007 µm. Most of the particles (90%) in electrocautery smoke are ≤6.27 µm in size, but surgical masks cannot filter particles smaller than 5 µm. In this situation, 95% of the smoke particles which pass through the mask reach deep into the respiratory tract and frequently cause various symptoms, such as headache, dizziness, nausea, eye and respiratory tract irritation, weakness, and abdominal pain in the acute period. The smoke can transport bacteria and viruses that are mostly between 0.02 µm and 3 µm in size and there is a risk of contamination. Among these viruses, SARS-CoV-2, influenza virus, HIV, HPV, HBV must be considered. The smoke may also carry malignant cells. The long-term effects of the surgical smoke are always ignored, because causality can hardly be clarified in individual cases. The quantity of the smoke changes with the technique of the surgeon, the room ventilation system, the characteristics of the power device used, the energy level at which it is set, and the characteristics of the tissue processed. The surgical team is highly exposed to the smoke, with the surgeon experiencing the highest exposure. However, the severity of exposure differs according to certain factors, e.g., ventilation by laminar or turbulent mixed airflow or smoke evacuation system. In any case, the surgical smoke must be removed from the operation area. The most effective method is to collect the smoke from the source through an aspiration system and to evacuate it outside. Awareness and legal regulations in terms of hygiene, toxicology, as well as occupational health and safety should increase.

Viral load of SARS-CoV-2 in surgical smoke in minimally invasive and open surgery: a single-center prospective clinical trial. Sci Rep 2023; 13:20299. [PMID: 37985848 PMCID: PMC10662446 DOI: 10.1038/s41598-023-47058-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 11/08/2023] [Indexed: 11/22/2023] Open
Abstract
At the beginning of the COVID-19 pandemic, it was assumed that SARS-CoV-2 could be transmitted through surgical smoke generated by electrocauterization. Minimally invasive surgery (MIS) was targeted due to potentially higher concentrations of the SARS-CoV-2 particles in the pneumoperitoneum. Some surgical societies even recommended open surgery instead of MIS to prevent the potential spread of SARS-CoV-2 from the pneumoperitoneum. This study aimed to detect SARS-CoV-2 in surgical smoke during open and MIS. Patients with SARS-CoV-2 infection who underwent open surgery or MIS at Heidelberg University Hospital were included in the study. A control group of patients without SARS-CoV-2 infection undergoing MIS or open surgery was included for comparison. The trial was approved by the Ethics Committee of Heidelberg University Medical School (S-098/2021). The following samples were collected: nasopharyngeal and intraabdominal swabs, blood, urine, surgical smoke, and air samples from the operating room. An SKC BioSampler was used to sample the surgical smoke from the pneumoperitoneum during MIS and the approximate surgical field during open surgery in 15 ml of sterilized phosphate-buffered saline. An RT-PCR test was performed on all collected samples to detect SARS-CoV-2 viral particles. Twelve patients with proven SARS-CoV-2 infection underwent open abdominal surgery. Two SARS-CoV-2-positive patients underwent an MIS procedure. The control group included 24 patients: 12 underwent open surgery and 12 MIS. One intraabdominal swab in a patient with SARS-CoV-2 infection was positive for SARS-CoV-2. However, during both open surgery and MIS, none of the surgical smoke samples showed any detectable viral particles of SARS-CoV-2. The air samples collected at the end of the surgical procedure showed no viral particles of SARS-CoV-2. Major complications (CD ≥ IIIa) were more often observed in SARS-CoV-2 positive patients (10 vs. 4, p = 0.001). This study showed no detectable viral particles of SARS-CoV-2 in surgical smoke sampled during MIS and open surgery. Thus, the discussed risk of transmission of SARS-CoV-2 via surgical smoke could not be confirmed in the present study.

Abstract
Surgical smoke is a byproduct of aerosols containing several components produced by energy equipment. The characteristics of surgical smoke components produced by different types of tissues or using different kinds of energy devices vary. For example, the average diameter of smoke particles produced by electrocautery is smaller, and the possibility of viable cells and pathogens in surgical smoke produced by an ultrasonic knife is higher. According to the characteristics of its composition, surgical smoke may be an important risk factor affecting the health and safety of operating room staff and patients. The use of surgical masks, suction devices and portable smoke evacuation systems can reduce this risk to some extent. However, most operating room staff members do not implement corresponding measures to protect themselves. In this paper, the characteristics of surgical smoke and the research progress in protective measures are briefly reviewed.

Abstract
BACKGROUND This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. METHOD Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. RESULTS Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year 'Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P < 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P < 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P < 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P < 0.001). CONCLUSIONS Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes.

Comparison of surgical smoke between two approaches for endoscopic thyroidectomy and open thyroidectomy. BMC Surg 2022; 22:420. [PMID: 36482383 PMCID: PMC9733340 DOI: 10.1186/s12893-022-01870-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Accepted: 11/28/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Surgical smoke has been recognized as a potential health risk by an increasing number of researchers. Moreover, the counts of surgical smoke produced during different surgical approaches are different. This study aimed to measure and compare the particulate matter (PM) of surgical smoke generated during open thyroidectomy and two endoscopic approaches for thyroidectomy to provide guidance for safe clinical practices. METHODS Forty-eight patients with thyroid cancer admitted to our hospital from June 2020 to December 2021 and treated with different surgical approaches were enrolled in this study. The total and peak counts of PM, dynamic changes, and other characteristics of surgical smoke produced during surgery were recorded. PM was classified as PM2.5 (size ≤ 2.5 μm) and PM10 (size ≤ 10 μm). RESULTS In a single cut, both the peak and total counts of PM2.5 and PM10 of surgical smoke in the open thyroidectomy group (n = 15) were significantly higher than those in the breast approach endoscopic thyroidectomy with CO2 insufflation group (n = 15) and the gasless transaxillary endoscopic thyroidectomy group (n = 18) (p < 0.001). Moreover, the latter two groups showed no significant differences in the peak and total counts of PM2.5 and PM10 (p > 0.05). CONCLUSION In thyroid surgery, more surgical smoke is produced during open thyroidectomy than during endoscopic thyroidectomy, while different endoscopic approaches showed no significant difference in surgical smoke production. Thus, endoscopic approaches outperform the open thyroidectomy approach with regard to surgical smoke production.

Abstract
The novel coronavirus disease 2019 (COVID-19) caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread at a very fast rate, overwhelming and disrupting healthcare systems around the world since its outbreak in December 2019 in China. As of October 2021, the total number of COVID-19 cases exceeds 240,000,000, and the total number of deaths is close to 5,000,000. In the situation of widespread SARS-CoV-2 infection, restrictions on the medical system due to shifts in medical care to accommodate the pandemic will occur, and its impact on surgical and endoscopic treatment for colorectal cancer is inevitable. Therefore, it is necessary to satisfy all of the following requirements: patient safety, prevention of exposure of healthcare workers including surgeons, prevention of nosocomial infection, and a decision on how to treat the primary disease. Surgical triage is also required, based on comprehensive consideration of the patient's condition, the severity of the disease, the SARS-CoV-2 infection situation in the region, and the medical supply system at each facility, including medical resources, human resources, and the availability of medical equipment. Understanding the diagnostic and treatment environment that the COVID-19 pandemic has dramatically changed is important in providing appropriate surgical care to patients who require surgery while taking utmost care to prevent the spread of COVID-19.

Patient with gastric cancer who underwent distal gastrectomy after treatment of COVID-19 infection diagnosed by preoperative PCR screening. Surg Case Rep 2022; 8:12. [PMID: 35038069 PMCID: PMC8761870 DOI: 10.1186/s40792-022-01367-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 01/11/2022] [Indexed: 11/16/2022] Open
Abstract
Background Because of the coronavirus disease 2019 (COVID-19) pandemic, preoperative screenings for COVID-19 infection are often performed in many institutions. Some patients are diagnosed with COVID-19 infection by antigen tests or polymerase chain reaction (PCR) testing for COVID-19, even if they have no symptoms, such as fever or respiratory symptoms. We herein describe a patient with gastric cancer who underwent distal gastrectomy 6 weeks after recovering from COVID-19 infection diagnosed by preoperative PCR. Case presentation An 86-year-old man was transferred to our hospital because of hematemesis and melena. A hemorrhagic gastric ulcer was found in the lesser curvature of the antrum by emergency endoscopy. Endoscopic hemostasis was performed, and he was discharged after recovery. A tumor-like lesion in the lesser curvature of the antrum was found on repeat endoscopy and was diagnosed as well-differentiated adenocarcinoma by biopsy. There was no evidence of lymph node metastasis or distant metastasis; therefore, we planned radical surgery. However, he was diagnosed with COVID-19 infection by preoperative PCR screening. Although he had no symptoms, such as fever or respiratory symptoms, he was hospitalized because of his advanced age. He was discharged 10 days after admission, and repeat COVID-19 PCR was negative. We planned radical surgery for the stomach tumor 6 weeks after recovery from the COVID-19 infection. A PCR-negative COVID-19 status was confirmed again before hospitalization. Open distal gastrectomy with Billroth I reconstruction was performed. We avoided ultrasonic scalpels and used a Crystal Vision 450D surgical smoke evacuator (I.C. Medical, Inc., Phoenix, AZ, USA) to reduce intraoperative surgical smoke. The postoperative course was uneventful. Conclusion Because of the COVID-19 pandemic, some patients are diagnosed with COVID-19 infection by preoperative antigen tests or PCR, even if they have no symptoms. If possible, elective surgery should be performed 4 to 6 weeks after recovery from COVID-19 infection to maximize safety. Moreover, surgeons must consider intraoperative surgical smoke.

Abstract
The impacts of coronavirus disease 2019 (COVID-19) have been globally paradigm shifting in all aspects. Surgeons have experienced unprecedented changes regarding operation schedules, preparations before surgery, and the precautions needed both during and after surgery. Many medical centers simultaneously reported a decrease in their numbers of surgeries, whether they were elective or emergent, or for cancerous or benign resections. However, accumulated surgical outcomes from the last 2 years of experience presented postoperative morbidity and mortality data that were comparable to the pre-pandemic era, whether in elective or urgent settings. Although COVID-19 showed a significant association with postoperative morbidity and mortality, the majority of noninfected patients could be treated successfully with stringent mitigation protocols. Initially recommended to be avoided at the start of the pandemic, minimally invasive surgery seems to be safe and feasible according to reported surgical outcomes. Numerous sets of guidelines have now been produced from medical societies and adhering to the basic precautions has been found to be practicable. It is crucial that health care systems and surgical staff remain vigilant and attentive to the ever-changing situation in this pandemic in order to provide optimal medical support to their patients.

Abstract
BACKGROUND In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak. METHODS From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study. RESULTS A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM. CONCLUSION Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide.

Laparoscopic surgery produced less surgical smoke and contamination comparing with open surgery: the pilot study in fresh cadaveric experiment in COVID-19 pandemic. BMC Surg 2021; 21:422. [PMID: 34915893 PMCID: PMC8675110 DOI: 10.1186/s12893-021-01432-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2021] [Accepted: 12/06/2021] [Indexed: 12/20/2022] Open
Abstract
Background The SARS-CoV2 virus has been identified in abdominal cavity of the COVID-19 patients. Therefore, the potential viral transmission from any surgical created smoke in these patients is of concern especially in laparoscopic surgery. This study aimed to compare the amount of surgical smoke and surgical field contamination between laparoscopic and open surgery in fresh cadavers. Methods Cholecystectomy in 12 cadavers was performed and they were divided into 4 groups: laparoscopic approach with or without smoke evacuator, and open approach with or without smoke evacuator. The increased particle counts in surgical smoke of each group were analyzed. In the model of appendectomy, surgical field contamination under ultraviolet light and visual contamination scale between laparoscopic and open approach were compared. Results Open cholecystectomy significantly produced a greater amount of overall particle sizes, particle sizes < 5 μm and particle sizes ≥ 5 μm than laparoscopic cholecystectomy (10,307 × 103 vs 3738 × 103, 10,226 × 103 vs 3685 × 103 and 81 × 103 vs 53 × 103 count/m3, respectively at p < 0.05). The use of smoke evacuator led to decrease in the amount of overall particle sizes of 58% and 32.4% in the open and laparoscopic chelecystectomy respectively. Median (interquatile range) visual contamination scale of surgical field in open appendectomy [3.50 (2.33, 4.67)] was significantly greater than laparoscopic appendectomy [1.50 (0.67, 2.33)] at p < 0.001. Conclusions Laparoscopic cholecystectomy yielded less smoke-related particles than open cholecystectomy. The use of smoke evacuator, abeit non-significantly, reduced the particles in both open and laparoscopic cholecystectomy. Laparoscopic appendectomy had a lower degree of surgical field contamination than the open approach.

Knowledge about the effects of electrosurgery smoke among operating room nurses during COVID-19 Pandemic: A Cross-Sectional Study. ACTA ACUST UNITED AC 2021; 24:100189. [PMID: 34179520 PMCID: PMC8214320 DOI: 10.1016/j.pcorm.2021.100189] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 06/02/2021] [Accepted: 06/14/2021] [Indexed: 12/28/2022]
Abstract
Background Electrosurgery smoke is the smoke emitted from tissue cauterization when using the electrosurgery device. Accordingly, in this smoke, more than 80 harmful toxins have been discovered. In the current study, we aimed to investigate the level of knowledge reported by the operating room nurses on the effects of electrosurgery smoke during the current COVID-19 pandemic. Methods This descriptive, survey-based cross-sectional study was performed on 533 OR nurses in all the referring hospitals of COVID-19 infection. The required information were collected using a questionnaire regarding the knowledge on the side effects of electrosurgery smoke. The obtained data were then analyzed using t-test and ANOVA by SPSS software. Results Most of the included participants (93.6%) had a low level of awareness and only a small number of them (0.4%) had a good level of knowledge on the effects of electrosurgery smoke. As well, a significant relationship (P˂0.05) was found between the level of knowledge reported by the OR nurses and the type of hospital (educational or private). Most of the studied hospitals used no electrosurgery smoke reduction equipment during electrosurgery. Conclusion The level of knowledge reported by the OR nurses was generally poor. It is recommended that managers and health officials try to increase the level of awareness of OR nurses during the COVID-19 pandemic by providing standard and protective equipment as well as holding some well-organized and related training courses.
