Case Report: Double lumen tube insertion in a morbidly obese patient through the non-channelled blade of the King Vision ™ videolaryngoscope

Abstract

We describe the insertion of the double lumen endobronchial tube (DLT) using a non-channeled standard blade of the King Vision TM videolaryngoscope for one lung ventilation (OLV) in a morbidly obese patient with a predicted difficult airway, severe restrictive pulmonary function, asthma, and hypertension. The patient was scheduled for a video-assisted thoracoscopic lung biopsy. The stylet of the DLT was bent to fit the natural curve of the #3 non-channeled blade of the King Vision ™ videolaryngoscope. We conclude that the use of King Vision ™ videolaryngoscope could offer an effective method of DLT placement for OLV.
