Introduction: There is great concern and risk of transmission of COVID-19 infection from the aerosolized smoke during laparoscopic surgery although there is a lack of enough literature to prove this. To minimize these risks and get the benefi t of laparoscopic surgery, we used a low-cost fi ltration system connected to an underwater seal bag fi lled with a 5% sodium hypochlorite solution.Materials and Methods: This is a retrospective study of prospectively maintained data of cases of laparoscopic surgeries using a low-cost fi ltration device system connected with an underwater seal bag fi lled with 5% sodium hypochlorite solution. Use of personal protective equipment, minimal staff in operative theatre, preoperatively testing of patients before admission for surgery was done. During surgery, minimal use of electrocautery in low power setting maintaining low pneumoperitoneum and cautious desuffl ation of smoke during and end of the procedure from one of the trocars fi tted to heat and moisture exchanger Filter, connected through a tube to 5 % sodium hypochlorite solution in underwater seal bag was performed.Results: During the lockdown from May 2020 to October 2020, 41 elective laparoscopic surgeries were done. All patients were tested negative before the procedure. No staff in operation theatre developed symptoms of COVID-19 or tested positive for COVID-19 infection for up to 2 weeks period.Conclusions: In this Pandemic situation, we have to co-habit with this SARS-Cov-2 virus. Minimally invasive surgeries can be continued with safety measures with modifications like the use of low-cost filtration devices for smoke filtration and evacuation.

Pathogen Reduction

Sodium hypochlorite (100 ppm), copper ion water (1 ppm), and sonication (22 to 44 kHz and 44 to 48 kHz) were assessed individually and in combination for their ability to reduce populations of Escherichia coli O157:H7 and Listeria monocytogenes on apples and in apple cider. Commercial unpasteurized cider was inoculated to contain approximately 106 CFU/ml of either pathogen and then sonicated at 44 to 48 kHz, with aliquots removed at intervals of 30 to 60 s for up to 5 min and plated to determine numbers of survivors. Subsequently, whole apples were inoculated by dipping to contain approximately 106 CFU/g E. coli O157:H7 or L. monocytogenes, held overnight, and then submerged in 1 ppm copper ion water with or without 100 ppm sodium hypochlorite for 3 min with or without sonication at 22 to 44 kHz and examined for survivors. Treated apples were also juiced, with the resulting cider sonicated for 3 min. Populations of both pathogens decreased 1 to 2 log CFU/ml in inoculated cider following 3 min of sonication. Copper ion water alone did not significantly reduce populations of either pathogen on inoculated apples. However, when used in combination with sodium hypochlorite, pathogen levels decreased approximately 2.3 log CFU/g on apples. Sonication of this copper ion–sodium hypochlorite solution at 22 to 44 kHz did not further improve pathogen reduction on apples. Numbers of either pathogen in the juice fraction were approximately 1.2 log CFU/ml lower after being juiced, with sonication (44 to 48 kHz) of the expressed juice decreasing L. monocytogenes and E. coli O157:H7 populations an additional 2 log. Hence, a 5-log reduction was achievable for both pathogens with the use of copper ion water in combination with sodium hypochlorite followed by juicing and sonication at 44 to 48 kHz.

Low Levels

Abstract Satisfactory microbiological values were obtained for animal feeds containing low levels of cblortetracycline (CTC), 5.0–40g CTC/ton. Results were comparable when calculated against both compensating CTC standard curves prepared from blank feed extracts and laboratory-inactivated CTC feed extracts. The inactivation of CTC in animal feed extracts by 5.25% sodium hypochlorite solution and heat was investigated, and it appeared to offer a convenient alternative for preparing compensating CTC standard curves.
