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
A randomized controlled trial compares the risk of respiratory depression between esketamine-based and fentanyl-based analgesia during liver ablation guided by high-frequency harmonic scalpel. If esketamine shows superior respiratory safety, it could become a viable treatment option.
