In patients with SARS-CoV-2 pneumonia, atelectasis might appear in up to 24% of patients, reports a recent study conducted at the Critical Care Department and Pain Unit, Puerta de Hierro Universitary Hospital - Majadahonda, Madrid, Spain.

Álvaro Mingote along with a team of researchers aimed to estimate the prevalence of atelectasis assessed with computer tomography (CT) in SARS-CoV-2 pneumonia and the relationship between the amount of atelectasis with oxygenation impairment, Intensive Care Unit admission rate and the length of in-hospital stay.

The research is published in the BMC Pulmonary Medicine Journal. The authors included a total of two-hundred thirty-seven patients, all of whom were admitted to the hospital with SARS-CoV-2 pneumonia and diagnosed by clinical, radiology and molecular tests in the nasopharyngeal swab who underwent a chest computed tomography because of a respiratory worsening.

Patients were divided into three groups depending on the presence and amount of atelectasis at the computed tomography: no atelectasis, small atelectasis or large atelectasis. In all patients, clinical severity, oxygen-therapy need, Intensive Care Unit admission rate, the length of in-hospital stay and in-hospital mortality data were collected.

The results from the study revealed that thirty patients (19%) showed small atelectasis while eight patients (5%) showed large atelectasis. One hundred and seventeen patients (76%) did not show atelectasis at all. Patients with large atelectasis compared to patients with small atelectasis had lower SatO2/FiO2, needed more days of oxygen therapy, more frequently Intensive Care Unit admission and a longer period of hospitalization.

Hence, this led the authors to conclude that in patients with SARS-CoV-2 pneumonia, atelectasis might appear in up to 24% of patients and the presence of larger amount of atelectasis is associated with worse oxygenation and clinical outcome.
