Secondary pneumonia in critically ill ventilated patients with COVID-19

We studied the microbial composition and diagnostic microbiology results of bronchoalveolar lavage (BAL) samples taken from adult COVID-19 patients and non-COVID-19 patients receiving artificial ventilation in a teaching hospital ICU. We observed that although COVID-19 patients had a greater incidence of VAP, the causative pathogens were similar in both groups.

本研究针对某教学医院重症监护室（Intensive Care Unit, ICU）内，取自接受人工通气的成年新型冠状病毒肺炎（COVID-19）患者与非COVID-19患者的支气管肺泡灌洗（bronchoalveolar lavage, BAL）样本，分析其微生物组成与诊断微生物学检测结果。我们观察到，尽管COVID-19患者的呼吸机相关性肺炎（Ventilator-Associated Pneumonia, VAP）发生率更高，但两组患者的致病病原体相似。
