Nerve blocks may offer better pain relief for appendicitis patients in the ER
NCT ID NCT06808087
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of nerve blocks (TAP and ESPB) to standard pain medication (tramadol) for people with acute appendicitis in the emergency department. The goal was to see if these blocks could reduce pain before surgery and lower the need for opioids. The trial included 96 adults and was completed at a single hospital in Turkey.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nerve block (TAP block or ESPB block)
- What this could lead to
- If successful, this could show that nerve blocks are a better way to manage appendicitis pain in the ER, possibly reducing the need for strong painkillers like opioids.
- What could go wrong
- This is a small, completed study with only 96 participants. The results may not apply to all patients, and nerve blocks carry risks like infection or allergic reaction.
