Smell Abnormalities Caused by Sars-Cov2 Infection: A Literary Review
Context: COVID-19 is an infectious disease caused by SARS-CoV-2 that started at the end of 2019, in Wuhan, spreading to multiple countries. This virus can produce symptoms of superior and inferior respiratory infection, cardiac lesions, and death. Among many other symptoms, disturbances in the sense of smell and taste are reported by patients. Even though most viral infections of the upper respiratory tract present anosmia associated with the infection, in the case of the SARS-CoV2 infection, these symptoms can happen in its absence. Because of this, the recovery time for anosmia caused by CoV2 can occur within a few weeks, while typical viral anosmia generally lasts for months. Goals: Understand the specificities of the olfactory affections caused by SARS-CoV2 infection.
The Assessment of Prone Position in Severe Acute Respiratory Syndrome
Introduction: Acute respiratory distress syndrome (ARDS) is a frequent condition associated with high mortality, acute alveolar damage, loss of lung compliance and hypoxemia. The prone position has been used to improve oxygenation in patients with moderate to severe hypoxemia with PaO2/FiO2<150, with this maneuver the lung compliance increases, associated with more homogeneous lung expansion and better gas exchange. Aims: Primary: To evaluate the effectiveness of the prone position in patients with acute respiratory distress syndrome. Secondary: Understand the respiratory physiology involved in the use of prone position in patients with acute respiratory distress syndrome. Methods: This work is a narrative review of literature in the Google academic, Scientific Electronic Library Online (Scielo), Medline and Cochrane databases, 22 articles were selected between 2001 and 2020. The keywords used were “prone positionâ€, “respiratory distress syndrome†and “acute lung injuryâ€.
