Summary

This study tests whether adding ketamine to a standard abdominal pain block (TAP block) reduces pain after total abdominal hysterectomy better than the block alone. Thirty women aged 25–60 will be randomly assigned to receive either bupivacaine alone or bupivacaine plus ketamine. Pain levels and the need for extra pain medication will be tracked for 24 hours after surgery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
bupivacaine with ketamine
What this could lead to
If it works, this could offer better pain control after hysterectomy and reduce the need for extra painkillers.
What could go wrong
This is a small, early-phase trial with only 30 participants, so results may not apply widely. Adding ketamine could also cause side effects like dizziness or nausea.
