Airway measurement study for laryngeal mask use in adults
This study looks at how differences in the throat and face affect the placement of a breathing tube used during surgery. It may help doctors choose the right size or position for better breathing support during procedures.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 40 years old or older than 65.
- You are having surgery that can use a laryngeal mask airway (a breathing tube placed in the throat).
- You have not had surgery on your upper airway (nose, throat, or voice box).
- You do not have a history of acid reflux, stomach ulcers, or bleeding in the stomach.
- You have no recent lung or airway infections, and no lung conditions like COPD or cystic fibrosis.
- You can open your mouth wide enough, do not have loose teeth, and have no allergy to ultrasound gel.

Other trials that look related to this one.
This trial tests a new way to place a breathing tube (laryngeal mask) using pressure monitoring to reduce side effects in older patients during surgery. It may help if you are 60 or older and having planned surgery that lasts 30 minutes to 2 hours.
This trial tests two different types of laryngeal masks (breathing tubes that sit in the throat) to see which works better during minor urologic procedures. It is for adults having surgery in a lying-down position (on the back or with legs in stirrups) under general anesthesia.
This trial compares two different devices (a video laryngeal mask and a video laryngoscope) used to help you breathe during surgery. It aims to see which tool works better for placing a breathing tube in patients having planned surgery under general anesthesia.
This study looks at how neck size relates to airway management during surgery. It may help doctors prepare better for placing a breathing tube.
This study tests a way of managing the air pressure in a breathing tube mask used during surgery. The goal is to reduce throat and voice box problems after surgery in older patients.
This trial compares a newer laryngeal mask airway (a device that helps you breathe during surgery) with the traditional inflatable one. It aims to see which one works better and may be more comfortable for patients having routine surgery.
