Rectus sheath block added to parasternal block may improve postoperative pain control and respiratory performance after cardiac surgery: a superiority single-blinded randomized controlled clinical trial
Authors' conclusion
The addition of a rectus sheath block with a parasternal block improves analgesia for cardiac surgery requiring chest drains emerging in the epigastric area.
