Pain relief study for anal surgery with spinal anesthesia
Part of Pain clinical trials.
This study tests if adding certain medications to a low-dose spinal anesthetic can improve pain control during and after anal surgery. It may help patients with hemorrhoids, anal fissures, or anal fistulas feel less discomfort.

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 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 compares two ways to manage pain during and after lower back surgery: one uses an ultrasound-guided nerve block, the other uses a medication called dexmedetomidine. The goal is to see which provides better pain control with fewer side effects.
This study compares two medications (dexmedetomidine and fentanyl) mixed with a numbing agent to see which works better for blocking pain during above-knee amputation surgery in patients with serious heart or lung disease. Both drugs are already used in anesthesia, and this trial tests which combination is safest and most effective for you.
This study tests a new combination of pain blocks for people having laparoscopic (keyhole) colon or rectal surgery. The goal is to see if adding a back muscle block to the standard abdominal wall block provides better pain relief.
