Rectus Sheath Block in Cardiac Surgery

September 18, 2025 updated by: Ali Nima Shariat, Icahn School of Medicine at Mount Sinai

This is a prospective, randomized study. The purpose of this study is to evaluate the effect of post-surgical pain control of a type of peripheral nerve block, Rectus Sheath Block.

  1. Does the rectus sheath block decrease opioid consumption postoperatively after cardiac surgery?
  2. Does the rectus sheath block decrease VAS pain scores postoperatively after cardiac surgery? Study participants will be assigned to receive either rectus sheath block or no block.
