Park JW, Jo JH, Park JH, et al. - Researchers performed this randomised controlled study to assess the impacts of fibreoptic-guided advance of double-lumen tube (DLT) on postoperative sore throat as well as airway injuries related to intubation. This inquiry was performed at tertiary hospital, Seongnam, Korea, from January 2018 to January 2019, and involved 123 patients undergoing one-lung ventilation with a left-side DLT. The participants were randomly allocated to two groups: a conventional group and a fibreoptic-guided group including 62 and 61 participants, respectively. In the conventional group, the DLT was rotated left 90° and advanced blindly into the left main bronchus, following entering the glottis. Experts advanced DLT into the main bronchus under the guide of fibreoptic bronchoscope, which had been passed through the bronchial lumen and inserted into the left main bronchus, in the fibreoptic-guided group. Findings revealed that fibreoptic-guided advancement appeared to decrease irritation to the airway, resulting in less postoperative complications (including sore throat, tracheal injury, and vocal cord injuries).
