Background:
Bilateral erector spinae fascial plane blocks (ESPB) offers a novel, alternative method of regional post-operative pain control to thoracic epidural analgesia (TEA). The aim of this study was to compare rates of postoperative hypotension, and other standard enhanced recovery after surgery (ERAS) endpoints, in patients receiving ESPB versus TEA for open hepatopancreaticobiliary (HPB) surgery.
Materials And Methods:
This retrospective analysis compared historical controls of ERAS patients undergoing open HPB surgery with TEA versus ESPB. The incidence of postoperative hypotension and clinical outcomes, including opioid requirements, were compared.
Results:
Forty patients receiving TEA were compared to 27 ESPB patients. Return of bowel function and length of stay (mean 7.2 versus7.4 days; P = 0.83) were similar. ESPB patients received less intraoperative colloid (142cc versus 340cc; P = 0.01) and had less postoperative hypotension versus TEA (22% versus 55%; P = 0.03). No ESPB patient required patient-controlled analgesia (versus 32.5% TEA; P< 0.001). ESPB MME requirements decreased over time, while TEA MME requirements increased over 72 hours (P = 0.019).
Conclusions:
ESPB is a novel method that shows promising outcomes in improving enhanced recovery parameters and minimizing opioid administration in open HPB surgery.
