Laryngeal Mask Airways clinical trials

Second-Generation Laryngeal Mask Airway vs Endotracheal Intubation in Adult Liver Transplantation

The Effect of Ultrasonographic Airway Measurements and Anatomical Differences on Laryngeal Mask Placement in Young and Older Adults: A Prospective Observational Study

AI ultrasound check for breathing tube placement

This trial tests if an artificial intelligence system can help doctors use ultrasound to confirm that a breathing tube (called an LMA) is placed correctly during surgery. If the AI works well, it might make anesthesia safer for patients.

Comparing three laryngeal masks for side-lying surgeries under general anesthesia

This trial tests three different breathing tube devices (laryngeal masks) used during general anesthesia when patients are lying on their side. The goal is to see which one works best for surgeries lasting less than three hours.

Test of a throat breathing device for people with neck radiation

This study tests how well a specific airway device works during general anesthesia for people who had radiation therapy to the neck. It may help improve safety and comfort during planned surgeries.

Supraglottic airway for newborn breathing support

This study tests whether a special breathing tube placed above the voice box (called a supraglottic airway) works better than the usual mask or tube to help newborns who need breathing support right after birth. It is for babies born at or after 34 weeks of pregnancy.

Comparing two airway tubes for young children under anesthesia

This study compares two types of soft breathing tubes (laryngeal mask airways) used during surgery in children ages 3–6. Researchers want to see which one works better and is safer for keeping the airway open during anesthesia.

Comparing two types of laryngeal mask airways for surgery

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.

Comparing two breathing devices for shoulder surgery

This trial tests two types of breathing tubes (SafeLM and I-gel) to see which works better for people having shoulder surgery while sitting up. It aims to find a safer way to keep your airway open during the procedure.

Comparing two airway devices for septoplasty

This trial compares a video laryngeal mask with a breathing tube during septoplasty (nose surgery) to see which works better. If you are having this surgery, you may be able to join.

Managing breathing tube pressure to reduce throat problems in older adults

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.

Breathing tube vs throat airway during gallbladder surgery

This trial compares two ways of managing your breathing while you are under anesthesia for elective laparoscopic gallbladder removal. It aims to see which option needs less anesthesia and is safer and easier to use for patients like you.

Airway device study for preterm babies needing breathing help

This study tests a supraglottic airway device (a tube that sits above the voice box) versus a face mask for helping premature babies breathe right after birth. It may help doctors choose the best way to support your baby's first breaths.

Finding the best dose of ciprofol for children's breathing mask

This study tests a new sedative medicine (ciprofol) to find the best dose for placing a breathing tube mask in children during surgery. It may help your child get a safer, more comfortable experience.

Comparing two airway devices in elderly patients

This trial tests whether placing the I-gel or classic laryngeal mask airway in different head positions works better for elderly patients during surgery. It aims to find the safest way to help you breathe while you are asleep.

Video laryngeal mask study for military medics

This trial tests a video laryngeal mask (a breathing tube with a camera) used by military medics for airway management during planned surgeries. It aims to see if it works well for patients needing help breathing during anesthesia.

Comparing Two Airway Devices for Children During Surgery

This study compares two soft plastic airway devices (I-Gel and Air-Q) used to help children breathe safely during surgery. The trial will determine which device works better and is safer for children aged 1–10 years.

Airway rod for intubation in adults with obesity

This trial tests if a special rod helps place a breathing tube more easily in adults with obesity who are having planned surgery. It could make the procedure safer and more comfortable.

Swapping breathing tubes before waking for safer recovery

This study looks at whether replacing a breathing tube (endotracheal tube) with a mask-like device (laryngeal mask airway) before the child wakes up from anesthesia can make recovery smoother and safer.

Comparing two airway devices for children's hernia surgery

This trial compares a laryngeal mask airway with a breathing tube in children having laparoscopic hernia repair. It aims to see which method works better.

Opioid-free anesthesia with spontaneous breathing for VATS lung nodule surgery

This trial tests a way to do VATS lung nodule surgery without using strong painkillers (opioids) and while you keep breathing on your own. It may help you recover faster with fewer side effects.

Laryngeal mask placement in elderly patients

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.

Tests safer airway method to reduce anesthesia “waking up” issues

This study looks at whether a combined airway method during general anesthesia can reduce unpleasant or risky “emergence” problems as you wake up. It is for people having planned laparoscopic (camera) surgery and who can follow fasting and consent rules.

Comparing three breathing tube devices for head-down laparoscopic surgery

This study is comparing three different breathing tube devices (GMA-TULIP, I-gel, and BlockBuster Laryngeal Mask) for people having laparoscopic surgery while tilted head-down. The goal is to see which device works best and most safely.
