Can a simple mist calm your heart during surgery?
NCT ID NCT07596004
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if a drug given as a mist before surgery can lessen the sudden rise in heart rate and blood pressure when a breathing tube is placed. About 66 adults having planned surgery will receive either the drug or a saltwater mist. The goal is to see if the drug makes the procedure safer and more comfortable.
