OUTCOME OF NON-INVASIVE VENTILATION IN COVID-19 PATIENTS

Abstract

Introduction: In covid-19, signicant number of patients developed severe respiratory symptoms and Acute Hypoxemic Respiratory Failure(AHRF) that required oxygen support. Initially treatment included early intubation and invasive ventilation, but Non-invasive ventilation(NIV) has been proven to be an effective bridging adjunct in early part of disease process and may prevent the need for invasive mechanical ventilation, which also decreases the risks to health care workers. Aims & Objectives: To study the outcome of non-invasive ventilation in covid-19 patients ;Primary outcome is number of patients recovered and death, Secondary outcome is the need for invasive mechanical ventilation Materials & Methods: This prospective study was conducted in the Department of Pulmonary Medicine, Dr.PSIMS & RF, which included 84 patients of covid-19 admitted in intensive care unit (ICU) during the period of May 2020 to November 2020. All patients were treated with NIV as per the requirement and followed up with laboratory parameters , CXR and outcome was studied during the course of hospital stay. Observation And Conclusion: out of 84 patients studied,67% recovered , 33% died . 19 patients required invasive mechanical ventilation. Age of < 65yrs ;SPO2 of 88-92% at the time of presentation, absence of obesity ;Normal C-Reactive protein(CRP) and Ferritin with Mild involvement on chest x-ray and longer duration of NIVhas better recovery rate. So, by our study we conclude that NIVhas a denite role in management of COVID-19 and also decrease the need for invasive ventilation .
