Lidocaine in throat or vein to check eye pressure after intubation
Part of Ear, nose & throat, Eyes & vision clinical trials.
This study compares two ways of giving a numbing medicine (lidocaine) before a breathing tube is placed during anesthesia. The goal is to see if giving it in the throat or through the vein affects pressure behind the eyes.

This study looks at how the carbon dioxide gas used during keyhole kidney cancer surgery affects the pressure behind your eye. The goal is to see if changes in gas pressure influence the nerve sheath that surrounds the optic nerve.
This study looks at how different blood pressure targets during nose surgery affect blood flow to the eye and the optic nerve. It aims to find the safest way to protect eye health during anesthesia.
This study tests two ways to numb the airway before placing a breathing tube while you are awake. It compares a nerve block injection versus a lidocaine mist to see which better controls heart rate and blood pressure during the procedure.
This trial compares two medications given during brain surgery to help control pressure around the optic nerve. The goal is to see which medication is better at protecting the eyes during the procedure.
This trial tests whether putting lidocaine gel on the breathing tube before surgery can reduce post-operative sore throat and coughing. It aims to make recovery more comfortable for patients having general anesthesia.
This study compares different numbing medicines (additives) mixed with lidocaine to see which works best for pain relief during eye surgery. All patients will receive a numbing injection around the eye (peribulbar block) to keep you comfortable during the procedure.
