Comparison of adverse reactions
Hematoma, nausea, infection, vomiting
HEMATOMA, INFECTION
No nausea and vomiting occurred in the PENG group, but 3 cases occurred in the FICB group, and the difference was not statistically significant (P > 0.05). Hematoma, or infection at the puncture site, was observed between the two groups. Additionally, there were no instances of catheter displacement after surgery.
