Chang JE, et al. - GlideScope and lighted stylet were compared in terms of intubation time, success rate of first attempt at intubation, difficulty in double-lumen endobronchial tube (DLT) advancement toward the glottis, and postoperative sore throat and hoarseness in patients undergoing thoracic surgery using DLT intubation. Findings demonstrated that use of lighted stylet, compared with GlideScope, permitted easier advancement of the DLT toward the glottis in the oropharyngeal space and attenuated time for achieving DLT intubation.
