Postoperative analgesic effectiveness of ultrasound‐guided bilateral erector spinae plane block vs. rectus sheath block for midline abdominal surgery in a low‐ and middle‐income country: a randomised controlled trial

The use of erector spinae plane block and rectus sheath block for postoperative analgesia in midline abdominal procedures is becoming more common. However, the most effective and appropriate method remains unclear. We aimed to compare the postoperative analgesic effecacy of ultrasound-guided bilateral erector spinae plane blocks with rectus sheath blocks for midline abdominal surgery in a low- and middle-income country.
