We administered PENG blocks and performed catheter insertion for continuous infusions in patients with femur fractures on hospital admission. In this case series, we describe our initial experience of pain management in 10 patients with continuous infusion and its associated adverse events.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case series<\/jats:title>\n                  <jats:p>The PENG block was administered with an introducer needle. The catheter was then inserted 3\u2009cm beyond the needle tip. In three patients, blood aspiration through the catheter occurred. In each patient, the catheter was repositioned 0.5\u20131.0\u2009cm more medially. No blood aspiration or visible hematoma occurred subsequently. The presence of any vascular structure deep to the iliopsoas muscle was excluded postoperatively based on a Doppler color flow scan.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>Overall, eight patients had femoral neck fractures, and two patients had intertrochanteric fractures. All 10 patients reported good pain relief. The median (IQR) Numerical Rating Scale (NRS) score decreased from 7 (6\u20137) before the block to 2 (2\u20132.75) 20\u2009min after PENG catheter placement. The median (IQR) NRS score after 12, 24 and 48\u2009hours were 2 (2\u20133), 2 (2\u20133), and 2 (0.25\u20132), respectively. Patients underwent surgery 24\u201348\u2009hours following catheter placement. Catheters were removed by an Acute Pain Service nurse 72\u2009hours postinsertion. We want to highlight the potential for intravascular catheter placement in this anatomical region. Further studies are required to confirm if this is a technical error or an associated complication of continuous PENG blocks.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/rapm-2020-101446","type":"journal-article","created":{"date-parts":[[2020,8,13]],"date-time":"2020-08-13T01:51:06Z","timestamp":1597283466000},"page":"835-838","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":45,"title":["Continuous PENG block for hip fracture: a case series"],"prefix":"10.1136","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5240-6131","authenticated-orcid":false,"given":"Romualdo","family":"Del Buono","sequence":"first","affiliation":[{"name":"Anesthesia, Humanitas Mater Domini, Castellanza, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eleonora","family":"Padua","sequence":"additional","affiliation":[{"name":"Anesthesia, Humanitas Mater Domini, Castellanza, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5076-3693","authenticated-orcid":false,"given":"Giuseppe","family":"Pascarella","sequence":"additional","affiliation":[{"name":"Anesthesia, Policlinico Universitario Campus Bio-Medico, Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corina Gabriela","family":"Soare","sequence":"additional","affiliation":[{"name":"Department of Anesthesia and Intensive Care, Galway University Hospitals, Galway, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrico","family":"Barbara","sequence":"additional","affiliation":[{"name":"Anesthesia, Humanitas Mater Domini, Castellanza, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2020,8,12]]},"reference":[{"key":"2025101110231760000_45.10.835.1","doi-asserted-by":"publisher","DOI":"10.1097\/AAP.0000000000000707"},{"key":"2025101110231760000_45.10.835.2","doi-asserted-by":"publisher","DOI":"10.1136\/rapm-2018-100354"},{"key":"2025101110231760000_45.10.835.3","doi-asserted-by":"crossref","DOI":"10.1016\/j.jclinane.2019.109650","article-title":"Can high volume pericapsular nerve group (PENG) block act as a lumbar plexus block?","volume":"61","author":"Ahiskalioglu","year":"2020","journal-title":"J Clin Anesth"},{"key":"2025101110231760000_45.10.835.4","first-page":"2","article-title":"Is continuous peng block the new 3-in-1","volume":"10","author":"Santos","year":"2019","journal-title":"J Anesth Clin Res"},{"key":"2025101110231760000_45.10.835.5","first-page":"A210","article-title":"Esra19-0060\u2005efficacy of continuous pericapsular nerve group (peng) block for pain relief after hemiarthroplasty of the hip: A case report","volume":"44","author":"Soares","year":"2019","journal-title":"Regional Anesthesia &amp; Pain Medicine"},{"key":"2025101110231760000_45.10.835.6","doi-asserted-by":"publisher","DOI":"10.1002\/ar.1090580304"},{"key":"2025101110231760000_45.10.835.7","doi-asserted-by":"crossref","DOI":"10.1097\/00000658-192508000-00015","article-title":"Cysts of the ilio-psoas bursa","volume":"82","author":"Gatch","year":"1925","journal-title":"Annals of surgery"},{"key":"2025101110231760000_45.10.835.8","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1007\/BF00349741","article-title":"Synovial cysts of the hip joint and iliopsoas bursitis: a spectrum of imaging abnormalities","volume":"14","author":"Sartoris","year":"1985","journal-title":"Skeletal radiology"},{"key":"2025101110231760000_45.10.835.9","doi-asserted-by":"publisher","DOI":"10.1007\/s003300101041"}],"container-title":["Regional Anesthesia &amp; Pain Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/rapm-2020-101446","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,11]],"date-time":"2025-10-11T17:23:25Z","timestamp":1760203405000},"score":1,"resource":{"primary":{"URL":"https:\/\/rapm.bmj.com\/lookup\/doi\/10.1136\/rapm-2020-101446"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,8,12]]},"references-count":9,"journal-issue":{"issue":"10","published-online":{"date-parts":[[2020,9,18]]},"published-print":{"date-parts":[[2020,10]]}},"alternative-id":["10.1136\/rapm-2020-101446"],"URL":"https:\/\/doi.org\/10.1136\/rapm-2020-101446","relation":{},"ISSN":["1098-7339","1532-8651"],"issn-type":[{"value":"1098-7339","type":"print"},{"value":"1532-8651","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,8,12]]}}}
