Objective:
To determine whether adding bilateral erector spinae plane block (ESPB) to an opioid-free anesthesia (OFA) regimen reduces postoperative opioid requirements compared to intravenous (IV) lidocaine in patients undergoing laparoscopic sleeve gastrectomy.
Key Findings:
- Bilateral ESPB resulted in significantly lower postoperative opioid consumption compared to IV lidocaine within the first 24 hours.
- Patients receiving ESPB reported lower pain scores postoperatively.
- ESPB was associated with fewer side effects related to opioid use.
Interpretation:
The study supports the use of bilateral ESPB as an effective component of opioid-free anesthesia in laparoscopic sleeve gastrectomy, potentially enhancing postoperative recovery and reducing opioid-related side effects.
Limitations:
- Lack of blinding for participants and anesthesiologists may introduce bias.
- Single-center study limits generalizability of findings.
- Exclusion of patients requiring unplanned reoperation may affect outcome assessment.
Conclusion:
Bilateral erector spinae plane block is a beneficial addition to opioid-free anesthesia protocols in laparoscopic sleeve gastrectomy, leading to reduced opioid consumption and improved postoperative analgesia.
