Esketamine versus fentanyl as adjuncts to hepatic hilar nerve block for ambulatory percutaneous liver tumor ablation focusing on respiratory safety: protocol for a randomized controlled trial
Frontiers in Pharmacology September 17, 2025 Xiao Wang, Lijuan Yan, Jiaying Cai et al. 1 citation
This trial aims to provide Level I evidence comparing the respiratory depression risk between esketamine-based and fentanyl-based analgesia during HHNB-guided liver ablation. Should esketamine prove to be demonstrably superior in terms of respiratory safety, HHNB-esketamine has the potential to be a viable treatment option.
