Which is an alternative supraglottic airway device besides King LT and LMA?

• A. i-gel
• B. Endotracheal tube
• C. NPA
• D. OPA

Answer: (A)

The key idea is recognizing another supraglottic airway device that sits above the glottis to ventilate without entering the trachea. The i-gel fits this role as an alternative to the King LT and the LMA. It is a single-use supraglottic airway with a soft, noninflatable cuff made of a gel-like material that conforms to the airway anatomy, providing a quick seal around the laryngeal inlet without needing cuff inflation. This design often allows faster placement and reduces cuff-related trauma; many versions include an integrated gastric channel to vent the stomach and help reduce aspiration risk.

Endotracheal tube is a definitive airway placed into the trachea through the vocal cords, not a supraglottic device. Nasal and oropharyngeal airways are simple airway adjuncts that keep the passage open but do not seal around the glottis or provide a true ventilatory seal.
