Which of the following describes Murphy tubes?

The correct choice emphasizes that Murphy tubes feature a beveled end, which facilitates easier insertion and reduces trauma to the airway. Additionally, many Murphy tubes come equipped with a cuff that helps secure the tube in place and ensures proper ventilation by minimizing airway leakage. This design makes them suitable for various patients and different situations during anesthesia procedures, enhancing their effectiveness in maintaining controlled ventilation.

The other options do not accurately reflect the characteristics of Murphy tubes. Describing them as rigid tubes with no side holes misrepresents their design, as Murphy tubes typically have side holes that allow for ventilation beyond the cuff area. Stating that they are used only for long-term ventilation is misleading; Murphy tubes are versatile and can be employed for both short-term and long-term use as needed in various clinical scenarios. Lastly, suggesting that they are designed exclusively for feline patients overlooks their application across a broad range of species, including canines and other veterinary patients, making them a staple in veterinary anesthesia.
