Direct laryngoscopy with a straight blade

Direct laryngoscopy using a straight blade.
(A) The head is positioned with the right hand, and the mouth is opened using the fifth finger of the left hand (if necessary).
(B) Alternately, the mouth may be opened with the thumb and index finger of the right hand using a "scissor" technique.
(C) The laryngoscope blade is inserted under direct vision over the tongue and into the vallecula. One attempt may be made at this point to elevate the epiglottis by lifting upward on the laryngoscope handle at a 45-degree angle.
(D) If unsuccessful, the tip of the blade is used to directly retract the epiglottis, revealing the vocal cords and glottic opening.
