In Response to Comment on “Computed-Tomography-guided Percutaneous Bilateral Neurolytic Celiac Plexus Block with Alcohol for Upper Abdominal Visceral Cancer Pain”

First, I want to thank Dr. Ling Ye and his colleagues for reading my article and providing valuable feedback.In terms of the dexmedetomidine administration, the doses of dexmedetomidine added to long-acting local anesthetics ranged between a predetermined dose and a weight-based dose.As proven in previous studies, we use a predetermined dose (50 g) administered intravenously or perineurally as an adjuvant to local anesthetics (1,2).The study only included patients with ASA I or , excluding those with significant liver or renal dysfunction, heart failure, or severe arrhythmia.Then, while I agree that ropivacaine is safer than bupivacaine in terms of cardiac toxicity and adverse neurological manifestations, it is not available in my institute.Furthermore, a recent meta-analysis comparing the impact of adjuvants in ophthalmic regional anesthesia shows that our combination of lidocaine 2% and bupivacaine 0.5% was used in many trials (3).Lastly, the requirement for postoperative analgesia was the satisfaction-scoring criteria in our study.
