Popis: One lung ventilation (OLV) with collapse of the ipsilateral lung is a prerequisite for most thoracic surgical procedures. Double-lumen tube (DLT) is still the preferred method to isolate the lungs and fiberoptic bronchoscopy (FOB) is the gold standard for the confirmation of correct placement of the DLT. However, both these procedures are considered as a high-aerosol-generating procedures and are hazardous to the health workers, particularly at this time of the COVID-19 pandemic. We did nine thoracic surgery cases categorized as essential, requiring OLV during the ongoing period of the COVID-19 between April 2020 and May 2020 where we used Full view DLT for lung isolation. We present our case series which shows that the Full view VDLT can minimize or circumvent the use of FOB during OLV, and reduce the time taken to isolate the lungs thus reducing aerosol in the theater. None of the nine patients required FOB for confirmation of initial positioning nor for diagnosis of intraoperative malposition. The time taken to isolate the lungs was significantly less and the surgical positioning was done under real-time monitoring by visualizing the blue cuff distal to carina at all times. The real-time monitoring by the Full view VDLT offers the additional advantage of detecting any malposition even before it results in loss of isolation or desaturation. We conclude that the Full view VDLT is an efficient and safe alternative for lung isolation at this time of the COVID-19 pandemic.
