Background. The COVID-19 pandemic leads to several debates regarding the possible risk for healthcare professionals during surgery. SAGES and EAES raised the issue of the transmission of infection through the surgical smoke during laparoscopy. They recommended the use of smoke evacuation devices (SEDs) with CO2 filtering systems. The aim of the present study is to compare the efficacy of different SEDs evaluating the CO2 environmental dispersion in the operating theater. Methods. We prospectively evaluated the data of 4 group of patients on which we used different SEDs or standard trocars: AIRSEAL system (S1 group), a homemade device (S2 group), an AIRSEAL system + homemade device (S3 group), and with standard trocars and without SED (S4 group). Quantitative analysis of CO2 environmental dispersion was carried out associated to the following data in order to evaluate the pneumoperitoneum variations: a preset insufflation pressure, real intraoperative pneumoperitoneum pressure, operative time, total volume of insufflated CO2, and flow rate index. Results. 16 patients were prospectively enrolled. The [CO2] mean value was 711 ppm, 641 ppm, 593 ppm, and 761 ppm in S1, S2, S3, and S4 groups, respectively. The comparison between data of all groups showed statistically significant differences in the measured ambient CO2 concentration. Conclusion. All tested SEDs seem to be useful to reduce the CO2 environmental dispersion respect to the use of standard trocars. The association of AIRSEAL system and a homemade device seems to be the best solution combining an adequate smoke evacuation and a stable pneumoperitoneum during laparoscopic surgery.

Smoke Evacuation

When a fire occurs in a tunnel, it is of great importance to assure the safety of the occupants of the tunnel. This is achieved by creating smoke-free spaces in the tunnel through control of the smoke gases. In this paper, results are presented of a study concerning the fire safety in a real scale railway tunnel test case. Numerical simulations are performed in order to examine the possibility of natural ventilation of smoke in inclined tunnels. Several aspects are taken into account: the length of the simulated tunnel section, the slope of the tunnel and the possible effects of external wind at one portal of the tunnel. The Fire Dynamics Simulator of the National Institute of Standards and Technology, USA, is applied to perform the simulations. The simulations show that for the local behavior of the smoke during the early stages of the fire, the slope of the tunnel is of little importance. Secondly, the results show that external wind and/or pressure conditions have a large effect on the smoke gases inside the tunnel. Finally, some idea for the value of the critical ventilation velocity is given. The study also shows that computational fluid dynamics calculations are a valuable tool for large scale, real life complex fire cases. .

In the OR, electrical shocks and fire represent two very important risks and they occur more commonly than most people recognize. Electrical and fire safety in the OR is every team member’s responsibility. Prevention is the first step, but when incidents occur, optimal outcomes depend on concerted efforts. Thisapproach, along with a comprehensive electrical and fire safety program, is a continued effort to create a safer healthcare environment for every worker and patient. Understanding the basic principles of electricity and fire safety is the first step towards this goal. Unfortunately, many institutions do not involve the key players (surgery and anesthesia department members) in the education and preparation process. By involving all team members, optimal outcomes for patients at this vulnerable time may be achieved. Our patients expect us to know the risks and management of these potentially life-threatening occurrences. This chapter endeavours to facilitate these goals.   This review contains 9 figures, 3 tables, and 51 references Keywords: electrosurgical unit, fire extinguisher, ground fault circuit interrupter, grounding, ignition source, line isolation monitor, macroshock, microshock, Ohm law

Power Electronics is widely used in bioscience and medical instruments such as Electrosurgical Units, MRI and X-ray. An advance development in switch mode power supply leads to a new design topology of DC to DC convertor for Electrosurgical Systems. The new designed system has a capacity to produce high efficient output power with high resonance, this improves the performance of the surgery operation. This paper reports a Buck-Boost topology DC to DC (Flyback) converter with high power switching. The simulation results show an improved performance when compared to the existing system.
