The severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has become a matter of concern all over the world. This virus caused acute respiratory distress syndrome(ARDS) in almost 67% of patients, with 71% of total patients requiring mechanical ventilation. Oxygen therapy is prudent for patients suffering fromSARS-CoV-2 at different stages of the disease. The choice of different oxygen delivery devices depends on the patient's status and its availability. In this review we will discuss the pros and cons of several oxygen delivery devices, as well as the safety precautions and personal protective equipments.

Introduction: Coronavirus disease 2019 (Covid-19) has become a pandemic all over the world. Despite our familiarity with various protection devices, the high incidence among medical personnel is still worrisome. In this review, we provide several perioperative strategies regarding the management of daily cases in the Covid-19 pandemic setting. Methods: We used keywords (((((coronavirus[Title/Abstract]) OR (covid-19[Title/Abstract])) OR (ncov-19[Title/Abstract])) OR (SARS-cov-2[Title/Abstract]))) AND (perioperative[Title/Abstract]) in the National Library of Medicine (NLM) database to find eligible reports. Results: We found 32 articles from the NLM database. After eligibility screening, we found 25 eligible articles describing perioperative management during the Covid-19 pandemic that relates to the staff's safety. All eligible articles stress the importance of the negative-pressurized environment to deal with perioperative care of Covid-19 patients. In general, the use of personal protective equipment (PPE) and video laryngoscopy is also essential. Conclusion: The best protective suit to avoid health-care personnel from getting Covid-19 infection is proper training and self-discipline. This combined with cooperative, honest patients and proper PPE supply is vital in efforts to reduce the spread of the disease. Negative-pressure chambers, both in operating rooms and intensive care units, are essential in this pandemic. Unfortunately, they are not easily available in underdeveloped and developing countries.

Background: Pregnant women and neonates are susceptible populations in many infections. Health-care workers are facing a new challenge as only few data are available on the effect of coronavirus disease 2019 (COVID-19) on pregnancy. The aim of this review was to see the current recommendations regarding the perioperative management of the cesarean section in COVID-19 patients. Methods: We used the keywords of (((((coronavirus [Title/Abstract]) OR (covid-19 [Title/Abstract])) OR (ncov-19 [Title/Abstract])) OR (SARS-cov-2 [Title/Abstract]))) AND (Cesarean [Title/Abstract] or Pregnancy [Title/Abstract]) in the PubMed database to find eligible reports. We studied all titles and abstracts from the search results and removed irrelevant studies that did not comply with our research question. Two authors were assigned to assess the validity and reliability of the studies using the Joanna Briggs Institute's critical appraisal tool. The cutoff point for inclusion was 50% of the total checkmarks in each critical appraisal checklist. Results: We found 16 articles from the PubMed database based on keywords described earlier. After eligibility screening, we found seven eligible articles describing perioperative management of the cesarean section during the COVID-19 pandemic. Conclusion: There is no solid evidence that the cesarean section is protective against the transmission of COVID-19. The use of an appropriate biosafety level-3 protective suits is imperative in managing patients presenting for cesarean section with COVID-19 in an operating room. A negative-pressure environment, both in the operating room and incubator, should be prepared for such cases. Regional anesthesia is the recommended technique, but general anesthesia is preferable in specific maternity conditions.
