Profile of severe covid-19 ARDS patients in ICU

ABSTRACT

Background: COVID-19, an infectious disease caused by SARS-CoV-2 virus has reported to be a global pandemic. About 5% of the total develop severe ARDS. Aim: To study the clinical profile, comorbidities and outcome including mortality rate in severe Covid- 19 ARDS patients. Methodology: 40 cases of severe COVID 19 infection (P/F ratio<300) admitted in tertiary care ICU treated with standard covid protocol were included in the study. Their demography, severity of hypoxia, mode of ventilation and outcome analysed. Results: Out of the 40 patients admitted, 29 (72%) were discharged with 11 patients (38%) requiring home oxygen therapy. The most common comorbidities were diabetes mellitus (30%) and hypertension (22.5%). Mean hospital stay was 17 days, and 35 patients (87.5%) required ventilation of which 80% on NIV and 20% on Mechanical ventilation. The mortality rate was 27.5%. The P/F ratio and CRP values was statistically significant with mortality rate (p-value<0.05). Three patients (7.5%) on positive pressure ventilation developed pneumothorax. One patient (2.5%) developed pulmonary thromboembolism.14 patients (35%) were in MODS out of which 8 patients died. Conclusion: Mortality rate was less in patients with a high P/F ratio and low CRP levels at the time of admission. Severe COVID 19 patients admitted in the ICU had developed additional complications requiring interventions. Patients in MODS had high mortality rate. Most common comorbidity associated was diabetes mellitus.
