Summary
Brief summary (as posted)
It remains controversial whether paracervical block should be performed as a powerful strategy for pain relief in total laparoscopic hysterectomy (TLH), because convincing conclusions are difficult to draw because of the heterogeneous and contradictory nature of the literature. Therefore, the aim of this study was to evaluate the efficacy of paracervical blocks using with 0.5% bupivacaine prior to TLHs for benign gynecologic conditions on postoperative pain relief.
