Lung Abscess and Pyothorax in Critically Ill COVID-19 Patients: A Single-Center Retrospective Study.

Abstract

The mortality rate of patients with COVID-19 pneumonia requiring mechanical ventilation remains high. This study determined the percentage and characteristics of patients who developed lung abscesses or pyothorax and their mortality rates among adult patients with COVID-19 admitted to the ICU who required mechanical ventilation. Of the 64 patients with COVID-19 assessed, 30 (47%) developed ventilator-associated pneumonia (VAP), of whom 6 (20%) developed pyothorax or lung abscess. There were no statistically significant differences in patient characteristics, treatment after ICU admission, or outcomes between those with and without these complications, except for age. VAP complicated by Lung abscess or pyothorax was caused by a single organism, with Staphylococcus aureus (n = 4) and Klebsiella species (n = 2) being the primary causative agents. Occur infrequently in patients with COVID-19 requiring mechanical ventilation. Large-scale studies are required to elucidate their effects on clinical outcomes.
