Anesthesia Delivery Aides
Below are three tools used to deliver anesthetic gases to you during anesthesia. What primarily determines which device you will need during surgery is the type of surgery you’re having. The position your surgeon requires you to be placed for surgery is also a factor. As always, any questions you might have regarding the use of any of the devices below can be directed to the anesthesiologist or nurse anesthetist working with you.
Laryngeal Mask Airway (LMA)
The Laryngeal Mask Airway (LMA) is a soft pliable breathing tube that fits behind your tongue. It is not placed in your trachea (windpipe). It's placed after you are asleep. After it is placed, you will breathe through it on your own, and take in the anesthetic gases.
Endotracheal Tube (ETT)
This device is an endotracheal tube (ETT). It is stiffer and narrower than the LMA. It is placed after you are asleep. It is placed in your trachea (windpipe). Since it requires muscle relaxation, once it's placed the anesthesia machine will breath for you through the ETT.
Nasal Cannula
The third device is a nasal cannula. It is designed to deliver oxygen through 2 soft prongs placed in your nostrils. It is used for cases where a breathing tube is not needed.
