This trial compares two different medications (morphine and dexmedetomidine) given through a spinal injection to see which provides better pain relief after lumbar spine surgery. If you qualify, you will receive one of these treatments or a placebo to help manage your pain after the operation.
This trial tests whether adding one of two different medicines (dexmedetomidine or ketamine) to a numbing injection in the lower spine improves pain relief after back surgery. You would receive the injection while asleep during surgery to help manage pain afterward.
This study compares two medicines (dexmedetomidine and fentanyl) added to a spinal numbing shot for people having planned leg or knee surgery. The goal is to see which one works better to keep your blood pressure stable, and to make the numbing last while keeping you comfortable.
This study compares two ways to manage pain after lumbar spine surgery: a special injection near the back (erector spinae plane block) versus a sedative medication (dexmedetomidine). It aims to see which approach provides better pain relief with fewer side effects.
This study compares two different numbing techniques (nerve blocks) to help manage pain after open colorectal surgery. Both methods are injected near muscles in your abdomen to reduce the need for strong painkillers after surgery.
This study tests a pain management plan led by anesthesiologists for people having complex anorectal surgery. The goal is to see if this approach can better control pain and improve recovery.
