Ultrasound (US)-guided peripheral nerve blocks (PNBs) are effective in reducing pain and opioid consumption postsurgery. Liposomal bupivacaine (LB), shown effective in shoulder surgery, was approved in November 2023 for use in US-guided lower extremity blocks. This study compares the efficacy of LB in US-guided PNBs, surgeon-administered LB field blocks, and a control group using PNB with local anesthetic only.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This prospective, randomized, single-anonymized controlled study enrolled patients undergoing elective foot and ankle surgery from March 2022 to January 2023. Patients were assigned to one of 3 groups: US-guided PNB with local anesthetic only, US-guided PNB with LB or local mix, or surgeon-administered LB or local mix field block. Postoperative opioid use, opioid requirements in oral morphine equivalents, block duration, and Patient-Reported Outcomes Measurement Information System (PROMIS) scores were tracked.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 248 patients were included: 70 in the US-guided PNB with local anesthetic\u2013only group, 98 in the US-guided PNB with LB group, and 80 in the surgeon-administered LB field block group. Patients in the US-guided LB group took fewer opioid pills between postoperative day (POD) 0 and POD 4 (median 4.0 pills vs. 6.5 and 5.5 pills in the other groups,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.025).

Compared with both local anesthetic\u2013only blocks and surgeon-administered field blocks with liposomal bupivacaine, US-guided delivery provided more sustained analgesia. These findings suggest a potential benefit of liposomal bupivacaine in regional anesthesia protocols, though further studies are warranted to assess its generalizability across surgical subtypes and to evaluate long-term safety.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10711007251359634","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T09:23:09Z","timestamp":1757323389000},"page":"1147-1155","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Efficacy of Liposomal Bupivacaine in Ultrasound-Guided Peripheral Nerve Blocks for Postoperative Pain Management in Foot and Ankle Surgery"],"prefix":"10.1177","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0513-4262","authenticated-orcid":false,"given":"Jonathan","family":"McKeeman","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brendan","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajith","family":"Malige","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rebecca","family":"Bates","sequence":"additional","affiliation":[{"name":"Temple Medical School, St. Luke\u2019s Campus, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna Ng","family":"Pellegrino","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6994-3432","authenticated-orcid":false,"given":"James","family":"Lachman","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Luke\u2019s University Health Network, Bethlehem, PA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,9,8]]},"reference":[{"issue":"2","key":"e_1_3_3_2_2","first-page":"471","article-title":"Efficacy of regional anesthesia using ankle block in ankle and foot surgeries: a systematic review","volume":"26","author":"Albaqami MS","year":"2022","unstructured":"Albaqami MS, Alqarni AA.
