The Department of Anesthesiology has now purchased a new second-generation video laryngoscope, which has successfully solved the problem of difficult airway intubation during the performance of many anesthetics. By using the video laryngoscope to insert the tracheal tube, the anesthesiologist’s eyes are undoubtedly placed at the voice box, thus turning many difficult airways into simple airways. The video laryngoscope is the anesthesiologist’s right-hand man.
