Question

Murphy's eye is seen in

• A. Macintosh laryngoscope
• B. Endotracheal tube
• C. LMA
• D. Flexible laryngoscope

Answer 1

The Correct Option is B

Murphy's eye is a feature found in certain types of surgical equipment. To understand where it is found, let's analyze the provided options.

1. Macintosh laryngoscope: A tool primarily used for intubation by visualizing the vocal cords. It does not have a Murphy's eye.
2. Endotracheal tube: A device used for airway management during anesthesia or respiratory distress. The Murphy's eye is a secondary opening on the side of the endotracheal tube near the tip, designed to prevent complete obstruction of the airway if the main lumen is blocked. This option is correct.
3. LMA (Laryngeal Mask Airway): A supraglottic airway device that sits above the vocal cords, lacking the specific feature of a Murphy's eye.
4. Flexible laryngoscope: Used for examination of the throat and vocal cords, it does not feature a Murphy's eye.

Therefore, the correct answer is Endotracheal tube, where Murphy's eye is a crucial design element for ensuring patient safety during intubation.
