Ketamine to reduce pain after hemorrhoid surgery
Treatments studied
Part of Digestive system, Heart & circulation, Pain clinical trials.
This trial tests whether ketamine can lessen pain after hemorrhoidectomy (surgery for severe hemorrhoids). It may help reduce how much pain medicine you need during recovery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult age 18 to 100
- You are scheduled for hemorrhoid removal surgery (hemorrhoidectomy) for severe (Grade III or IV) hemorrhoids
- You are able to receive general anesthesia (you can be safely put to sleep for surgery)
- You do not have conditions that would prevent hemorrhoid surgery
- You do not have a history of schizophrenia or other hallucination-related psychiatric illness, and no history of psychosis

This study tests whether a nerve block (an injection to numb the area) can reduce pain after outpatient hemorrhoid surgery. It may help you recover with less discomfort.
This trial tests whether injecting botulinum toxin (Botox) into the anal muscle before hemorrhoid removal surgery can lower pain after the operation. It is for people with advanced hemorrhoids that have not gotten better with other treatments and who are already planning to have surgery.
This study tests whether the oral medication nifedipine, compared to a placebo (a sugar pill), reduces pain and speeds up healing after hemorrhoid surgery. If you are having hemorrhoidectomy, this could help you recover more comfortably.
This trial tests whether giving a medication called ketamine during heart surgery can reduce long-term pain after the operation. If it works, patients may recover with less chronic pain.
This trial tests if ketamine can reduce pain, opioid use, and improve mental health in adults recovering from serious orthopedic injuries. It may help those with high injury severity scores.
This study tests whether giving ketamine before or during surgery can reduce pain afterward. It is designed for adults with higher body weight who also have certain health conditions like well-controlled diabetes or blood pressure.
