A combination stylet and laryngotracheal anesthetizing cannula integrated into a flexible and elongated body for insertion within an endotracheal tube during intubation, and which guides the endotracheal tube from its interior during insertion within the patient's trachea, in combination with more efficiently anesthetizing the insertion region both before and during such as the intubation procedure. An attachable vial is provided which contains a reservoir of a topical anesthetic or other pharmacological agent, and which attaches to an end of the flexible body in proximity to a stop lock shaped portion, in turn exhibiting an annular end abutment iip or shoulder which, upon insertion within the endotracheal tube, defines an inserting limit to the stylet and outer flexible body. The elongated flexible body defines further includes a narrowed distal extension associated with the topical anesthetizing cannula projecting beyond an end configuration of the main body and, to a limited degree, beyond the distal end of the endotracheal tube. |
