Severe acute respiratory syndrome (SARS) is a novel coronavirus infection causing respiratory failure. Non-invasive ventilation (NIV) can be effective for SARS-related acute respiratory failure (ARF) while controlling infection risks for healthcare workers.

Area of Science:

  • Infectious Diseases
  • Pulmonology
  • Critical Care Medicine

Background:

  • Severe acute respiratory syndrome (SARS) is an emerging infectious disease caused by a novel coronavirus.
  • SARS presents with fever, respiratory symptoms, and often bilateral lung infiltrates, potentially progressing to respiratory failure.
  • Approximately 20% of SARS patients require intensive care due to disease severity.

Purpose of the Study:

  • To evaluate the efficacy and safety of non-invasive ventilation (NIV) in treating SARS-related acute respiratory failure (ARF).
  • To assess the risks of NIV, including barotrauma and infection transmission to healthcare workers (HCW).
  • To outline management strategies for patients with SARS-related respiratory failure.

Main Methods:

  • Review of clinical data and outcomes for SARS patients treated with NIV.

  • Analysis of complications associated with NIV, such as pneumomediastinum and pneumothorax.
  • Evaluation of infection control measures implemented during the SARS outbreak.

    • Main Results:

    • Non-invasive ventilation (NIV) was found to be efficacious in treating SARS-related ARF, with no reported infection risks to HCW.
    • The incidence of NIV-associated barotrauma ranged from 6.6% to 15%.
    • High mortality rates (34-53% at 28 days) were observed in intensive care units for SARS patients.

    Conclusions:

    • NIV can be a safe and effective treatment option for SARS-related ARF.
    • Patients failing NIV or with progressive respiratory deterioration require intubation and mechanical ventilation.
    • Strict infection control measures are crucial for preventing cross-infection to healthcare workers.
