Abstract
Objetivo: sistematizar a produção bibliográfica sobre as recomendações para o manejo e a mitigação do aerossol produzidos por instrumentos rotatórios de alta velocidade em tempos de epidemia pela COVID-19. Método: foi realizada uma busca bibliográfica no em bases bibliográficas eletrônicas brasileiras e internacionais (Lilacs, SciELO, MEDLINE e PubMed). Após aplicados critérios de inclusão e exclusão dos documentos, 21 estudos foram selecionados para a realização da revisão. Resultado: foi construída uma proposta com recomendações para reduzir a contaminação durante procedimentos geradores de aerossol provenientes de instrumentos rotatórios de alta velocidade. Conclusão: recomenda-se a utilização de equipamentos de proteção individual completo, incluindo respiradores N95, PFF2, PFF3 ou similar, o emprego de barreiras mecânicas, a aspiração através de bomba de alta eficiência, a constante renovação do ar ambiente através de sistemas de exaustão ou pressurização da sala de trabalho e a limpeza e desinfecção criteriosa do ambiente de trabalho após cada atendimento
Highlights
On March 11, 2020, the World Health Organization (WHO) officially declared the SARS-CoV-2 pandemic. This new coronavirus is responsible for the infectious disease called COVID-19.1 Its transmission can occur directly, through close contact with people infected by the inhalation of respiratory bioaerosols produced when a person speaks, coughs or sneezes, or by indirect transmission through contact with surfaces contaminated with SARSCoV-2 that is taken to the eye, nose or mouth mucosa.[2,3,4,5,6]
Our research question in this integrative review was: what are the recommendations for management and mitigation of aerosol generated in procedures that use high-speed rotary instruments in times of COVID-19 epidemic?13 The methodology for the integrative review had the following phases: (1) definition of the research question; (2) search for relevant studies; (3) selection of studies based on pre-established inclusion criteria; (4) data analysis and preparation, and (5) summary and communication of information
There was consensus on the recommendation to perform only urgent and emergency procedures, as well as, whenever possible, the replacement of techniques that require the use of rotary instruments during the COVID-19 epidemic period
Summary
On March 11, 2020, the World Health Organization (WHO) officially declared the SARS-CoV-2 pandemic This new coronavirus is responsible for the infectious disease called COVID-19.1 Its transmission can occur directly, through close contact with people infected by the inhalation of respiratory bioaerosols produced when a person speaks, coughs or sneezes, or by indirect transmission through contact with surfaces contaminated with SARSCoV-2 that is taken to the eye, nose or mouth mucosa.[2,3,4,5,6]. These aerosols, if contaminated by SARS-CoV-2, pose a risk to professionals and patients treated.[6,11] In this occupational risk group, dental surgeons are at the top of the list, but other surgical specialties in medicine such as otolaryngology, head and neck surgery, neurosurgery and plastic surgery, use techniques that demand the use of high-speed rotary equipment in regions with high viral load, in addition to remaining very close to the patient’s face during surgery
