Compositions and methods of use related to formulations comprising anesthetics are generally described. Some embodiments are directed to compositions comprising a plurality of micelles and / or particles, and an anesthetic contained internally. These can be used to control and / or prolong the duration of IVRA while reducing the risk of systemic toxicity commonly due to administering anesthetics. The control and / or prolonged duration of IVRA may be due, at least in part, to the attachment of the sufficiently small micelles and / or particles to a biointerface (e.g., blood vessel surface) where the composition has been administered. Conventional IVRA methods commonly do not utilize potent and long-acting anesthetics (e.g., bupivacaine) due to the risks of cardiac toxicity. The compositions and methods described herein, however, provide a pathway for increased safety and efficiency of the use of such anesthetics, in certain embodiments. Resultantly, the performance (e.g., anesthetic distribution) of the micelles and / or particles internally containing an anesthetic may be comparatively better than the performance of free anesthetic, e.g., with respect to nerve blood and systematic drug distribution.

A wound dressing including a porous biosynthetic polymer film comprising a poly(lactide-co-caprolactone) (“PLC”) copolymer or other suitable polymer matrix, and a local analgesic loaded therein, to provide pain relief over an extended period of time (e.g., for 5-7 days), e.g., for healing of a partial thickness dermal injury. The PLC copolymer may have a particular lactide / caprolactone molar ratio (e.g., from 2:1 to 9:1) to ensure slow, sustained release of the bupivacaine or other analgesic. The dressing may provide a water vapor transmission rate from 1000 g / m2·day to 3000 g / m2·day to facilitate fast healing and regrowth of new epithelial tissue beneath the dressing. The dressing is configured to remain positioned over the dermal injury, providing wound protection for about 14 days, after which is simply debrides away, falls off, or is easily and painlessly removed, once new epithelial tissue regrows.
