Summary

This trial tests if ketamine can help reduce pain in patients having surgery for severe hemorrhoids. Ketamine is given during the operation to block pain signals in the brain. The study compares patients who receive ketamine with those who do not. Ketamine has been studied for its potential to reduce postoperative pain and opioid consumption, but results have been mixed.

Who is the study for?
This trial is for adults aged 18-100 who are having surgery (hemorrhoidectomy) for severe hemorrhoids (Grade III or IV). They must be able to have general anesthesia and not use strong painkillers regularly. People with a history of schizophrenia, other hallucinatory psychiatric illnesses, or psychosis cannot participate.
What is being tested?
The study is testing if ketamine can help with pain after hemorrhoid surgery. About 100 patients will either receive ketamine or no ketamine while under anesthesia, without knowing which group they're in; however, the researchers will know.
What are the potential side effects?
Ketamine may cause side effects such as feelings of disconnection from reality, changes in perception like sights and sounds, confusion, agitation, elevated blood pressure and heart rate.

Awards & Highlights

Pivotal Trial
The final step before approval, pivotal trials feature drugs that have already shown basic safety & efficacy.
Drug Has Already Been Approved

No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.

Trial Design

2Treatment groups
Active Control
Group I: Intraoperative ketamine infusionActive Control1 Intervention
Subjects in this group will receive standard anesthesia during surgery and a dose of ketamine at 0.3 mg/kg IV bolus prior to surgical incision. If the procedure lasts more than 1 hour, an additional bolus dose will be given.
Group II: Control groupActive Control1 Intervention
This group will only receive the standard anesthesia during surgery with no ketamine.

Other Research
Hemorrhoid treatments often focus on reducing pain, inflammation, and swelling. Anesthetics like ketamine work by blocking NMDA receptors in the brain, which helps in reducing pain perception and providing analgesia. This is particularly useful for hemorrhoid patients undergoing surgical procedures, as it can help manage postoperative pain effectively. Other common treatments include NSAIDs, which reduce inflammation by inhibiting cyclooxygenase enzymes, and corticosteroids, which decrease inflammation and immune response. Understanding these mechanisms is crucial for hemorrhoid patients as it helps in selecting the most appropriate treatment to manage symptoms effectively and improve recovery outcomes.
