postoperative pain, nerve block, pain
Here, we describe an ESP block for postoperative pain control after abdominal oncologic procedures. We found ESP blocks to be safe, technically simple, and effective for postoperative pain management after elective oncologic abdominal procedures. However, in light of relatively high VAS score rates and opioid requirements observed at 24 hours after surgery, likely as a result of a rebound pain mechanism after nerve block, we advise an appropriate postoperative pain protocol and patient education to improve clinical outcome. This study contributes to the ongoing research into the implementation of ESP blocks as a viable pain treatment protocol, suggesting its efficacy but advising it as part of a comprehensive postoperative pain protocol.
