Randomized Controlled Trial
Distance from the glottis to the grille: the LMA Unique, Air-Q and CobraPLA as intubation conduits: A prospective, randomised trial.
Supraglottic airway devices are often used in airway management to facilitate tracheal intubation. Knowledge of the distance from the grille of the device to the patient's vocal cords is essential for the safe passage of the tracheal tube below the vocal cords. ⋯ Using the LMA Unique as a conduit for tracheal intubation may pose a safety risk, whereas the use of the Air-Q would position the tracheal tube at a safe depth in the trachea.
