4.1. Limitations
NRS, anxiety, pain
Performing the ESP block near the surgical site and informing patients about the block in such a way that it did not cause fear and anxiety before surgery were two challenges of this study. Despite our efforts in teaching the patients, the possibility of incorrect use of the PCA pump and underestimated or exaggerated reporting of pain on the NRS by patients should also be considered as limitations of this study. Finally, the lack of sufficient research to compare our study's findings regarding the ESP block's side effects against the literature should also be noted.
