Pain relief showdown: ketamine vs fentanyl for gallbladder surgery
NCT ID NCT07670052
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two drugs, ketamine and fentanyl, added to a standard numbing medicine (bupivacaine) to control pain after laparoscopic gallbladder removal. 84 adults aged 20-50 will receive one of the two combinations during surgery. The goal is to see which provides longer-lasting pain relief and reduces the need for additional painkillers.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ketamine and fentanyl (as adjuvants to bupivacaine)
- What this could lead to
- If it works, this could point toward a better way to manage pain after gallbladder surgery, reducing the need for strong painkillers.
- What could go wrong
- This is a small, early-phase trial (84 people) comparing two common drugs, so any benefit may be modest or not apply to everyone. Risks include side effects from the drugs themselves.
