Ultrasound study of airway measurements in pregnancy
Part of Women’s health & pregnancy clinical trials.
This study uses ultrasound to measure the airway in pregnant women (with and without preeclampsia) and non-pregnant women. It helps doctors predict how easy or difficult it might be to place a breathing tube during delivery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a pregnant woman at 32 weeks or more of pregnancy, or a non-pregnant woman of childbearing age.
- If pregnant, you may have normal blood pressure (normotensive) or preeclampsia (high blood pressure with protein in urine).
- You are at least 150 cm (about 4 feet 11 inches) tall.
- Your body mass index (BMI) is 30 or lower.
- You do not have seizures from preeclampsia (eclampsia).
- You do not have other causes of airway difficulty, such as neck swelling, facial deformity, or prominent teeth.

This study uses ultrasound to look at children's airways before planned surgery under general anesthesia. It aims to help doctors better predict the right size of breathing tube, which could reduce complications.
This study uses ultrasound to look at your child's airway before surgery to see if placing the breathing tube might be difficult. The goal is to help doctors plan better and keep your child safe during anesthesia.
This study compares two ways of using ultrasound to look at the airway in women with severe preeclampsia who need a C-section under general anesthesia. It aims to find which technique is better, so doctors can prepare more safely for your breathing tube placement.
This trial uses ultrasound to measure children's airways before surgery, aiming to predict if placing a breathing tube will be difficult. It could help doctors prepare better and keep kids safer during anesthesia.
This study tests whether ultrasound scans and simple body measurements can help doctors predict when placing a breathing tube during surgery might be difficult. If successful, it could help doctors plan safer anesthesia care.
This study uses an ultrasound to look at the upper airway in adults having planned surgery with general anesthesia and a breathing tube. It may help doctors understand airway anatomy better.
