One-hour premedication to prevent CT contrast allergies in emergencies
Part of Immune system & allergy clinical trials.
This study tests whether a one-hour premedication can prevent allergic reactions to CT contrast dye. If you have a known allergy to this dye and need an emergency CT, you might be eligible.
Summary written for real people, not researchers, by Clin2.

This study is testing a new way of taking CT scans that may give doctors more information. If you are already scheduled for a CT scan, you may be able to have an extra scan using this new method.
This study looks at whether an allergy to contrast media (the dye used in scans) lasts over time. If you've had a reaction before, participating may help doctors understand if the allergy goes away or stays.
This trial tests a personalized way to calculate contrast dye for CT scans, based on your sex and body measurements. It may improve safety and image quality.
This study looks at how to improve the preparation and imaging techniques for heart CT scans. It may help make the scan more comfortable and accurate for people who already have a heart CT scheduled.
This trial tests whether a simple inorganic nitrate pill can protect your kidneys from damage caused by contrast dye used in heart catheterization or CT scans. It is for people whose kidneys are already somewhat weak, making them at higher risk for this type of injury.
This study compares giving fluids through a vein versus drinking fluids to lower the risk of sudden kidney injury after a CT scan with contrast dye. It focuses on adults with very poor kidney function who are scheduled for an elective CT scan.
