Carotid ultrasound test to guide fluid during major abdominal surgery
This study uses a non-invasive ultrasound scan of the neck (carotid Doppler) to help predict whether you’ll benefit from extra IV fluids during major abdominal surgery. It aims to improve fluid management without placing extra invasive monitoring unless already planned.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old
- You are scheduled for major abdominal surgery
- You can give written consent (agree to join the study)
- You are not pregnant
- You do NOT have severe lung disease (for example advanced COPD or lung scarring)

This trial is testing a special way to monitor blood flow during carotid artery surgery to help keep patients safe. It may be a good fit if you are having planned carotid surgery and meet a few basic health criteria.
This study uses a simple ultrasound on the upper chest to check if children under general anesthesia need extra fluids. It aims to find a better way to manage fluid balance during surgery.
This trial is testing a special ultrasound (called transcranial Doppler) to monitor blood flow during a procedure to open a narrowed carotid artery in your neck. The ultrasound helps doctors see if the procedure is safe and working well.
This study tests whether a neck ultrasound (carotid Doppler) or a heart ultrasound (echocardiography) is better at determining how much fluid a septic patient on a ventilator needs. If you or your loved one is in the ICU with sepsis on a breathing machine, this trial helps doctors choose the best way to give fluids that can improve blood pressure and organ function.
This trial tests whether using a heart ultrasound before surgery can help doctors better manage your blood volume. If you are having surgery under general anesthesia and have a higher risk of heart problems, this study may help improve your safety.
This study tests a new 3D ultrasound technique that may give doctors a detailed picture of your neck and brain arteries before your carotid surgery. It does not involve any new medication—only an ultrasound exam with a contrast agent to improve the images.
