DIFFICULT AIRWAY

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 study looks at whether measuring the airway with ultrasound before surgery can help predict if placing a breathing tube using a video laryngoscope will be difficult. Researchers will compare ultrasound measurements to a standard difficulty score in 100 adults aged 18 to 80 u…

This study looks at whether ultrasound measurements of the airway can help predict which children will have a difficult time with breathing tube placement during surgery. Researchers will compare ultrasound images to a standard scoring system in 70 children aged 1-18. If ultrasou…

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 looks at whether rotating the head 45 degrees to the left improves the view of the vocal cords during video laryngoscopy in obese adults. Fifty patients with a BMI of 30 or higher will be observed. If the maneuver works, it could offer a simple way to reduce airway com…

This study looks at whether different flow rates of high-flow nasal oxygen change how well doctors can see the airway when placing a breathing tube. 150 adults having planned surgery will each be tested at three flow settings (0, 40, and 60 L/min). The goal is to find the best fl…

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 looks at whether using ultrasound can better predict if placing a breathing tube will be difficult in obese patients (BMI over 35). Researchers will compare ultrasound measurements of the neck with standard tests like the Mallampati score. 70 adults having planned surg…

This study tests a computer algorithm (EAP-LC) that uses CT scans to predict the best path for placing a breathing tube in laryngeal cancer patients. Researchers will compare the algorithm's predictions to actual tube placement videos from 70 patients. The goal is to see if the a…
