[Prolonged weaning after long-term ventilation due to SARS-CoV-2 infection: a multicenter retrospective analysis].

Unlabelled: Some of the patients with SARS-CoV-2 infection (COVID-19) received invasive ventilation during inpatient care. Weaning from ventilation was difficult for some patients (so-called prolonged weaning).

Patients: Patients (n=751) with prolonged weaning (reason for ventilation "pneumonia" and "acute respiratory failure") from four centers for the period 2011-23 from the "WeanNet" registry were used as a matched group.
