Clinical Case: Casual Finding of Part of an Intubation Guide after its Use for Exchange and Placement of Double Light Tube

A difficult airway is defined as a clinical situation in which a trained anesthesiologist has difficulties to ventilate a patient with a face mask, difficulties for endotracheal intubation, or both. Intubation with a double lumen tube (DLT) may be more difficult than an equivalent intubation with a single-lumen tracheal tube because of its greater external diameter, stiffness and concavity, so its use is not recommended as a technique of initiation in patients with VAD.
