Laparoscopic or robotic intraoperative management to minimize aerosol dispersion: Adaptations to the context of the COVID-19 pandemic. / Manejo intraoperatório em cirurgia laparoscópica ou robótica para minimizar a dispersão de aerossóis: Adaptações ao contexto da pandemia por COVID-19.

The coronavirus infection, also known as SARS-COV2, has proven to be potentially fatal, representing a major global health problem. Its spread after its origin in the city of Wuhan, China has resulted in a pandemic with the collapse of the health system in several countries, some with enormous social impact and expressive number of deaths as seen in Italy and Spain. Extreme intra and extra-hospital measures have been implemented to decrease the transmission and dissemination of the COVID-19. Regarding the surgical practice, a huge number of procedures considered non-essential or elective were cancelled and postponed until the pandemic is resolved. However, urgent and oncological procedures have been carried out. In this publication, we highlight and teach adaptations to be made with commonly used materials in laparoscopy to help prevent the spread and contamination of the healthcare team assisting surgical patients.

A infecção pelo coronavírus determinante da doença COVID-19, também conhecida como SARS-COV2 foi classificada nos últimos meses como pandemia. Essa é potencialmente fatal, representando enorme problema de saúde mundial. A disseminação, após provável origem zoonótica na cidade de Wuhan, China, resultou em colapso do sistema de saúde de diversos países, alguns com enorme impacto social e número grande de mortes descritas na Itália e Espanha. Medidas extremas intra e extra-hospitalares têm sido implementadas a fim de conter a transmissão e disseminação da COVID-19. No âmbito cirúrgico, enorme quantidade de procedimentos considerados não essenciais ou eletivos foram prorrogados ou suspensos até resolução da pandemia. No entanto, cirurgias de urgência e oncológicas não permitem que o paciente espere. Nesta publicação, sugerimos e ensinamos adaptação a ser feita com materiais de uso corriqueiro em laparoscopias para evitar a contaminação ou a disseminação entre as equipes assistenciais e os pacientes.

Guidance for otolaryngology health care workers performing aerosol generating medical procedures during the COVID-19 pandemic.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for Coronavirus disease 2019 (COVID-19) has a predilection for infecting the mucosa of the upper and lower airways. Otolaryngologists and supporting health care workers (HCWs) are particularly at high risk of becoming infected while treating patients as many in-office procedures and surgeries are Aerosol Generating Medical Procedures (AGMP). Based on a review of the literature and various guidelines, recommendations are made to mitigate the risk to health care workers of becoming infected with SARS-CoV-2 while providing clinical care. RECOMMENDATIONS: During the COVID-19 pandemic all elective and non-time sensitive Otolaryngology procedures should be deferred to mitigate the risk of transmission of infection to HCWs. For non-AGMPs in all patients, even COVID-19 positive patients Level 1 PPE (surgical mask, gown, gloves and face shield or goggles) is sufficient. If local prevalence is favourable and patients are asymptomatic and test negative for SARS-CoV-2, Level 1 PPE can be used during short duration AGMPs, with limited risk of infected aerosol spread. For AGMPs in patients who test positive for SARS-CoV-2 a minimum of Level 2 PPE, with adequate protection of mucosal surfaces, is recommended (N95/FFP2 respirator, gown, double gloves, goggles or face shield and head cover). For long duration AGMPs that are deemed high-risk in COVID-19 positive patients, Level 3 PPE can provide a higher level of protection and be more comfortable during long duration surgeries if surgical hoods or PAPRs are used. It is recommended that these procedures are performed in negative pressure rooms, if available. It is essential to follow strict donning and doffing protocols to minimize the risk of contamination. CONCLUSIONS: By following strict infection prevention recommendations, the risk of HCWs becoming infected with SARS-CoV-2 while treating patients can be minimized. As the COVID-19 pandemic evolves rapidly, these recommendations should serve as guidance and need to be interpreted based on local factors and availability of healthcare resources.
