A2 - Hadzic, Admir PY - 2017 T2 - Hadzic's Textbook of Regional Anesthesia and Acute Pain Management, 2e AB - Local anesthetics (LAs) are among the most useful drugs in anesthesiology practice and pain management. They are cornerstones in postoperative pain management within a multimodal analgesic pathway to reduce or eliminate opioids and their resulting adverse events. However, currently available LAs display a considerable range of onset and duration as well as tolerability across a wide range of uses, including infiltration, peripheral blocks, and epidural and spinal anesthesia. Their main limitation is duration of action, which in the treatment of postoperative pain may prevent adequate therapy of sufficient duration. For that reason, continuous catheter infusion systems are widely used but introduce challenges, such as catheter placement, catheter migration and maintenance, and the burden of the external pump. Therefore, long-acting LAs with predictable onset, delivery, and duration of action would be a near-ideal solution.
