Tracheal intubation

This trial tests an experimental drug called tegileridine to find the dose that best prevents sudden rises in blood pressure and heart rate when a breathing tube is placed during general anesthesia. The study includes adults aged 18 to 90 having elective surgery, with separate gr…

Researchers are observing whether the time of day affects how safely and quickly anesthesiologists place breathing tubes in surgical patients. They will compare intubations done during regular daytime hours with those done in the evening, at night, or on weekends. The study track…

This study tests whether a structured training program for ICU staff improves how often breathing tubes are placed successfully on the first try and reduces major complications, such as severe drops in blood pressure or oxygen levels, cardiac arrest, or death. Researchers will tr…

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 looks at whether adding a quick, painless ultrasound scan of the neck to a standard mouth exam can better predict if placing a breathing tube will be difficult. About 160 adults having planned surgery will be randomly assigned to either the standard exam alone or the s…

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…
