Conclusion
This feasibility study confirmed that ESP block is a safe and effective
technique under MAC sedation in a multimodal analgesic regimen for SICD
implantation and demonstrated a small but significant decrease in
intraoperative and postoperative opioid consumption that may be of
clinical importance in high-risk patients. Larger studies are needed to
further investigate and validate the utility and more importantly the
characteristics (ie. volume and concentration) of ESP blocks as a
standard for SICD implantation.
