Most anesthesiologists prefer using the double-lumen endobronchial tube (DLT) over the single-lumen endobronchial tube (SLT) with bronchial blockers because the former can enable faster localization and lung deflation and can ventilate each lung individually [Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) infection causes local mucosal epithelial damage in the pharynx and trachea, resulting in nonspecific inflammation; moreover, in some patients with poor immunity, SARS-CoV-2 infection can persist and lead to chronic inflammation [Various nonpharmacological and pharmacological approaches have been used to decrease the incidence of POST [We hypothesized that thermal softening of DLTs before intubation may reduce the incidence of intubation-related airway complications in patients with prior SARS-CoV-2 infection undergoing one-lung anesthesia.
