Letter to the Editor Regarding "Effect of Ropivacaine Intercostal Nerve Block Combined with Patient Controlled Intravenous Analgesia on Postoperative Analgesia After Breast Augmentation".

ABSTRACT

We read the recently published article "Effect of Ropivacaine Intercostal Nerve Block Combined with Patient Controlled Intravenous Analgesia on Postoperative Analgesia after Breast Augmentation" by You et al. We have noticed several issues in the methods and results of this study and would appreciate the responses from the authors. We question several aspects, opioid-sparing effect, sufentanil consumption, sample size evaluation, exclusion reasons, and side effects.
