Research progress of ultra-long-acting local anesthetics
Multimodal analgesia is the gold standard for postoperative pain management,and ultra-sound-guided nerve block as the cornerstone supplemented with fewer opioids and a sufficient amount of non-steroidal anti-inflammatory drugs(NSAIDs)throughout the entire course of the procedure is the most main-stream multimodal analgesic regimen at present.However,ultrasound-guided nerve blocks are limited by the duration of action of local anesthetics and often provide effective analgesia for surgical patients for no more than 8 hours,resulting in a low satisfaction rate of postoperative analgesia in surgical patients.With the con-tinuous research on the concept of rapid rehabilitation,how to extend the duration of action of local anesthet-ics is the focus and hotspot of research.Ultra-long-acting local anesthetics include liposomal bupivacaine and HTX-011,which have been applied in clinical practice,and quaternary ammonium derivatives,which are still in the research stage.In this paper,we will review the existing ultra-long-acting local anesthetics in terms of ultra-long-acting local anesthetics with extended-release systems,new pathways and targets of ultra-long-acting local anesthetics,and the development of ultra-long-acting local anesthetics in the form of brand-new compounds,so as to provide new ideas for the subsequent research and clinical application of ultra-long-acting local anesthetics.
