AIRWAY MANAGEMENT

This trial tests whether a high-flow nasal cannula (HFNC) can maintain oxygen levels better than a tight face mask during rapid sequence induction, a procedure used for emergency intubation. Adult patients needing intubation will be randomly assigned to receive preoxygenation wit…

This study tests a new device that combines a mouthpiece, airway support, oxygen delivery, and breathing monitoring into one tool for sedated endoscopy. About 1,500 adults will be randomly assigned to receive either this device or standard care. The goal is to see if it reduces e…

This study will observe nearly 5000 adult surgical patients to develop a better way to predict when placing a breathing tube with a video laryngoscope might be difficult. Researchers will create a new scoring system for the view of the voice box and compare it to existing methods…

This trial tests a new integrated tube-bougie prototype that combines the guidance of a bougie with an endotracheal tube into one device. Emergency medicine residents will use it, along with standard stylet and bougie techniques, on simulated normal and difficult airways. The goa…

This trial tests whether a video-assisted supraglottic airway device helps doctors insert a breathing tube more successfully on the first try compared to a conventional device. The study involves 204 adults undergoing planned surgery with general anesthesia. Neither device uses a…

This trial compares three devices—SPHJ-II, a video lighted stylet, and a visual fiberscope—for placing a breathing tube in adults under general anesthesia. About 549 participants will be randomly assigned to one device to see which gives the highest first-attempt success rate. Th…

This study looks at whether using ultrasound to measure neck tissue thickness can better predict difficult airway in obese patients undergoing surgery. Researchers will compare ultrasound measurements with standard tests in 52 adults. The goal is to improve safety during anesthes…

This study looks at whether adding mental rehearsal (practicing steps in your mind) to standard training helps medical staff learn emergency cricothyroidotomy, a procedure to open a blocked airway. About 60 doctors, residents, and nurses will take part. Researchers will measure h…

This study tests different doses of alfentanil (a painkiller) combined with propofol (a sleep medicine) to find the best amount for placing a laryngeal mask airway in children aged 7 to 12. The goal is to make the procedure smoother and safer. Forty children having day surgery wi…

This study will collect information on 1,200 emergency intubations across multiple hospitals in Taiwan. Researchers will track how often the tube is placed correctly on the first try and how often serious problems like low oxygen, low blood pressure, or cardiac arrest occur. The …

This study will test whether measuring the height from chin to neck (thyromental height) or using ultrasound to see neck tissues can better predict when placing a breathing tube will be hard. Researchers will watch 240 adults having planned surgery under general anesthesia. The g…

This study tests whether using a bedside ultrasound to guide throat suctioning can reduce lung infections and injuries in ICU patients on breathing machines. About 321 adults expected to need a breathing tube for at least 72 hours will take part. The goal is to see if this imagin…

This study will compare two methods of applying pressure to the neck during a breathing tube insertion procedure in 50 adults having elective surgery. Researchers want to see if pressing on the left side of the windpipe gives a better view of the vocal cords than pressing on the …

This study will compare two common airway devices used during elective surgery: the video laryngeal mask airway and the video laryngoscope. Researchers will measure how long it takes to place a breathing tube and how often it works on the first try. About 176 adults having planne…
