Safe laparoscopy during COVID-19 pandemic by SARS-CoV-2: bio innovation of the closed-circuit system

Background: Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) transmission during laparoscopy while using energy devices through the carbon dioxide pneumoperitoneum is a big concern in operation theatre. So, we had to alter the way we vent carbon dioxide through a closed-circuit system (CCS) to avoid contamination.Methods: We did a prospective study in the safety of the CCS during elective laparoscopic surgeries. We had recruited 184 patients from a single unit in three quarters. The first quarter had 52 patients where the SARS-CoV-2 status was unknown as rapid antigen test (RAT) and reverse transcription polymerase chain reaction (RT- PCR) was not done as per government guidelines. So, we presumed all patients to be potential carriers. Later in the 2nd and 3rd quarter we had recruited 132 patients; all were tested by RAT/RT-PCR and positive patients were excluded from our study. Postoperatively we observed for COVID-19 symptoms in our health care workers (HCW) and confirmed by RT-PCR.Results: Of the total 184 laparoscopic surgeries performed during this period, only 2 (1.09%) patients developed COVID-19 symptoms and this was in the 1st quarter when routine testing by RT-PCR was not done. None (100%) of our HCW developed symptoms of COVID-19.Conclusions: Closed circuit system is an innovative and safe technique during laparoscopy. We strongly recommend RT-PCR for COVID-19 before elective surgery.

Background: There is a big concern regarding transmission of Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) during laparoscopy and using energy devices through the carbon dioxide (CO2) pneumoperitoneum. So, we decided to use a novel indigenous innovative closed-circuit system (CCS) to avoid this contamination in operation theatre.Methods: We set out to do a prospective study in the safety of this innovative closed-circuit system in elective surgeries over 3 consecutive months of May to July 2020, during the peak of SARS-CoV-2 pandemic in a tertiary teaching hospital. We recruited 52 patients undergoing elective laparoscopic surgery in a single laparoscopy unit. The Coronavirus disease 2019 (COVID-19) status was unknown, so we presumed all patients to be potential carriers of SARS-CoV-2. However, we followed the Indian council for medical research (ICMR) and Government of Karnataka (GOK) guidelines of clinical screening before surgery. We observed the postoperative outcome regarding COVID-19 symptoms in Health care workers (HCW) involved in the operation theatre. If required, we do a real time reverse transcription polymerase chain reaction (RT-PCR) to find the true positives.Results: Of the total 52 (basic and advanced) laparoscopic surgeries performed during this period, only 2 (3.84%) patients turned positive in the postoperative period. They developed COVID-19 symptoms and were tested positive by RT-PCR. None (100%) of the HCW developed any symptoms of COVID-19.Conclusion: Closed circuit system is a safe and promising technique during laparoscopy.

Objective : To find out the role of additional dose of BCG vaccination in health care workers in prevention of COVID-19 infection Study design : A prospective study to find out the incidence of COVID 19 infection in healthcare worker exposed to COVID-19 indoor patients by doing RT- PCR testing at the end of 15 days of COVID duty. Setting : The study was conducted at Noida COVID Hospital, Noida District Hospital and Superspecialilty PG Teaching institute (SSPGTI) hospital, Noida Result : No Health care worker who received additional dose dose of BCG vaccination contracted COVID infection as confirmed by RT-PCR at the end of 15 days of indoor COVID duty (Nil out of 80 healthcare workers) whereas in controls i.e. those who were not vaccinated 28 out of 130 controls contracted COVID-19 infection. Conclusion : Additional dose of BCG vaccination after the age of 20 year in healthcare workers engaged in care of admitted COVID-19 patients has a protective role since the COVID status of the patients attending hospitals for any other ailments is not known routine BCG immunization of the medical staff is recommended

Carbon Dioxide Absorbent

Absorbents used in closed and semi-closed circuit environments play a key role in preventing carbon dioxide poisoning. Here we present an analysis of one of the most common carbon dioxide absorbents—soda lime. In the first step, we analyzed the composition of fresh and used samples. For this purpose, volumetric and photometric analyses were introduced. Thermal properties and decomposition patterns were also studied using thermogravimetric and X-ray powder diffraction (PXRD) analyses. We also investigated the kinetics of carbon dioxide absorption under conditions imitating a closed-circuit environment.
