Summary

This trial compares two types of nerve blocks for pain relief after open gastric cancer surgery. The blocks are injected near the abdominal wall to numb the area, potentially reducing the need for opioid painkillers, which can cause side effects like drowsiness and constipation. The study will measure pain scores and morphine use in 60 patients to see which block works better.

What this could mean

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

Active substance: Two regional nerve blocks: subcostal transversus abdominis plane (TAP) block and external oblique intercostal block, using local anesthetics.
What this could lead to: If one block proves better, it could become a standard way to manage pain after gastric cancer surgery, reducing opioid use and speeding recovery.
What could go wrong: This is a small study, and results may not apply to all patients. Nerve blocks carry risks like infection or bleeding, and pain relief may vary.
