Can a simple nerve block protect your heart during surgery?

NCT ID NCT07058194

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at whether giving a nerve block (erector spinae plane block) before or after gallbladder surgery affects heart electrical activity. 135 adults having laparoscopic gallbladder removal were randomly assigned to receive the block before surgery, after surgery, or no block. Researchers measured changes in a heart electrical marker (QRS-T angle) on EKGs taken before and one hour after surgery to see if the block timing made a difference.

Active substance
bupivacaine
What this could lead to
If successful, this could help anesthesiologists choose the best timing for nerve blocks to reduce heart-related risks during surgery.
What could go wrong
This is a small, early-stage study focused on a heart electrical marker, not on actual heart attacks or complications. The results may not change practice without larger trials.
