Elective Thoracic Surgery

The goal of this clinical trial is to know which type of laryngoscope is better for Double Lumen Tube (DLT) insertion, in participants undergoing elective thoracic surgeries. The main question aim to answer is Is C-MAC blade D video laryngoscope better than Macintosh laryngoscope for DLT insertion in term of time taking for intubation and hemodynamic changes to laryngoscopy? Researchers are comparing two groups of participants * Participants in Group A are receiving intubation from C-MAC blade D video laryngoscope. * Participants in Group B are receiving intubations from Macintosh laryngoscope.

The trial was designed as a single-centre, non-interventional prospective observational study to utilize deep learning technology combined with computed tomography (CT) images to precisely predict the pulmonary function indicators of thoracic surgery preoperative patients.
