Background and Aims: Liposomal bupivacaine (LB) is a formulation of local anesthetic that may exert analgesia over a prolonged period.Anecdotal use of LB suggests benefit and prolonged analgesia when used to supplement infiltration blocks.Our aim was to test the effect of a bolus of LB delivered through a nerve catheter in two types of interfascial plane blocks (transversus abdominis plane and anterior subcostal quadratus lumborum).The effect was evaluated through patient self-reporting of postsurgical pain up to 48 postoperative hours.

Material and Methods: Medical records of tata funko pop adult postoperative patients who received LB in fanimation triaire 52 a peripheral nerve catheter were followed retrospectively and analysed for pain scores and spread of dermatomal numbness over 48 h following the postoperative dose.A chart review of patients who qualified between June 2015 and March 2017 was performed, and clinical data were obtained from the institutional Perioperative Health Documentation System.Results: Pain scores decreased following LB bolus, and all patients reported efficient block analgesia after bolus injection.Dermatomal numbness decreased gradually and was minimal by 48 h following bolus.

Conclusion: LB can be injected through a peripheral nerve catheter to prolong analgesia after catheter removal.
