Warmed lidocaine for less pain during eye injections

This trial tests whether giving lidocaine (a numbing medicine) through an IV before and after surgery can help manage pain from burn injuries. It is designed for adults with small to moderate burns who need a wound cleaning procedure.

This trial tests if warming the numbing medicine before injecting it into the jaw makes the numbing work better for people with a painful tooth infection. If you have a bad toothache in a lower molar and need a dental procedure, this study might help make the numbing more effective.

This study tests whether a numbing injection (lidocaine) in the cervix can reduce pain during IUD placement. It's for women who have never had a vaginal birth and are getting their first IUD.

This trial tests whether injecting a numbing medicine (lidocaine) into the painful area helps people with chronic, unexplained pain in the anal or perineal region. It is for patients who have not gotten relief from standard treatments and whose MRI shows no other cause.

This study compares two pain-relief methods—nitrous oxide gas (laughing gas) and lidocaine numbing cream—to see which works better when doctors need to place a needle in your vein. If you've never used nitrous oxide before and are generally healthy, you may be a good fit.

This trial tests using a special catheter (thin tube) to deliver lidocaine—a numbing medication—to treat chronic pain on an outpatient basis. Researchers want to see if this approach helps manage long-term pain effectively.
