Compare a laryngoscope tool in obese vs nonobese men
This study compares how well a specific breathing tube placement tool (Airtraq) works in men who are obese versus men who are not, during planned surgeries. It may help improve the safety and ease of putting in a breathing tube.

Touch relaxation in ICU patients on a breathing machine
This study tests whether gentle touch therapy (like a hand or foot massage) helps reduce stress in patients who are on a breathing machine and sedated in the ICU. The goal is to make the recovery process more comfortable.
NiortAges 18 years+ - NCT06884592Recruiting
Predicting difficult breathing tube placement in septoplasty surgery
This study looks at factors that may predict difficult intubation (placing a breathing tube) in people having septoplasty surgery. It aims to find out how common this is and what signs might help doctors prepare better.
Başakşehir, IstanbulAges 18–65 - NCT07316179Recruiting
Predicting breathing tube placement in weight-loss surgery
This study compares two methods—a standard risk score (El Ganzouri index) and an ultrasound exam—to predict how easy it will be to place a breathing tube during weight-loss surgery. The goal is to find the best way to keep patients safe during anesthesia.
Antalya, AntalyaAges 18–65 - NCT06986187Recruiting
Predicting difficult airways in heart surgery patients
This study measures how often difficult airways occur during heart or blood vessel surgery and builds a way to predict them beforehand. It may help your care team prepare for safer airway management during your procedure.
AnkaraAges 18 years+ - NCT07470736Recruiting
Comparing intubation tools for difficult airways
This trial tests two different ways to help doctors put a breathing tube in a patient with a difficult airway. It compares using a video laryngoscope with a video stylet versus using a video laryngoscope with a fiberoptic scope in a simulated setting.
Kuala Lumpur, Bandar Tun RazakAges Any age - NCT06683599Recruiting
Oxygen via nasal tube for babies during breathing tube placement
This study tests whether giving extra oxygen through a small tube in the nose during placement of a breathing tube helps young children stay safer. It is for newborns and infants up to about 1 year old who need a breathing tube for surgery or other non-emergency procedures.
Perth, Western AustraliaAges 1 minute–12 months - NCT07278232Recruiting
Voice test to predict difficult breathing tube placement
This study uses a simple voice recording to see if your voice can help predict whether placing a breathing tube during surgery might be more difficult. It aims to make anesthesia safer for you.
ShanghaiAges 15–70 - NCT06601036Recruiting
Sevoflurane sedation for difficult airway patients
This study is testing a sedative medicine (sevoflurane) to help people with a difficult airway breathe more easily during a procedure. It may be an alternative to being awake while a tube is placed in your windpipe.
Tanta, El-GharbiaAges 18–50 - NCT01612949Recruiting
Photos to help predict difficult breathing tube placement
This trial looks at pictures of the face and neck to help classify which people are harder to place a breathing tube. It may help anesthesiology teams prepare and choose safer steps if a tube is difficult to insert.
Winston-Salem, North CarolinaAges 18–99 - NCT07384494Recruiting
High-flow oxygen vs regular oxygen for awake intubation with difficult airways
This trial compares two ways of giving oxygen during a procedure where you are awake but have a tube placed in your windpipe. It may help patients with airways that are hard to open safely.
Wuwei, GansuAges 18 years+ - NCT07245511Recruiting
Comparing intubation difficulty scales in children
This study compares three different scales used to measure how difficult it is to place a breathing tube using a video laryngoscope (a special camera tool) in children. It may help determine the best way to predict and manage airway challenges during surgery.
Ankara, TurkiyeAges 5–18 - NCT07309978Recruiting
Comparing ultrasound and physical measurements for predicting difficult airways
This study compares two methods—ultrasound of the upper airway and standard physical measurements—to predict which patients may have a difficult airway during surgery. The goal is to find a more reliable way to prepare for safe anesthesia.
AnkaraAges 18–99 - NCT07482436Recruiting
Airway ultrasound vs laryngoscopy in obesity
This study compares two ways of checking the airway before surgery in people with obesity: a breathing tube placed with the help of ultrasound (a handheld device that uses sound waves) versus a standard laryngoscope (a lighted tool). The goal is to see which method is safer and easier for larger patients.
TrabzonAges 18 years+ - NCT06881576Recruiting
Video study of intubation in children having surgery
This trial is studying how doctors place breathing tubes (intubation) in children during planned surgeries. Researchers will use video to review and improve the process, which may help make future procedures safer.

Common questions
- Are there clinical trials for intubation; difficult or failed?
- Yes. Clin2 currently lists 155 recruiting intubation; difficult or failed studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a intubation; difficult or failed trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a intubation; difficult or failed trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
