Endotracheal tube
If possible, the airway should be secured with an endotracheal tube. The most common technique is by direct laryngoscopy, and visualization of the tube passing through the cords.
The Macintosh (curved blade) is the most widely used blade, although most experts agree that the type of blade is less important than the provider"s comfort with the one they have.
The other common blade is the Miller (straight blade). It is most often used as a second-line blade, but some use it first. The choice of blade is a matter of preference but the technique is different depending on the blade you select. You should be skilled in both to accommodate the patient"s anatomic differences.
The one exception is with infants, where a straight blade works better to stabilize the more floppy epiglottis and displace the relatively larger tongue. [16]
