I'm using a otoscope with a wire guide (used for canulation of arteries) and a catheter (14G), but although the tip of the wire guide isn't too sharp sometimes injures the glottis. What is the best alternative to replace this guide, knowing that the guide diameter must to be less than 2,1 mm?
Thanks.

a metallic stellate is 2 mm diameter , can be used inside the tube , it is rigid enough , malleable and not sharp

Intubation of rats is possible without a guidewire. Supine position, hyperextended neck, pulled out tongue of the rat, diaphanoscopy of the trachea with a strong cold-light source and intubation with a blunt catheter. It works. You can see the entrance to the trachea shining in the throat.
