Phase 1: eight canine cadavers received one catheter per hemiabdomen, followed by injection of contrast media solution [low volume (LV) 0.3 mL kg\u22121 or high volume (HV) 0.6 mL kg\u22121]. Phase 2: postoperative pain of five dogs was managed by injecting 0.3 mL kg\u22121 of ropivacaine 0.5% through QL catheters every eight hours, up to 72 h after abdominal surgery. Pain was assessed using the Short Form of the Glasgow Composite Measure Pain Scale, and methadone 0.2 mg kg\u22121 was administered intravenously when the pain score was \u22656. The number of VBs stained by the contrast solution between the QL and psoas minor muscles was significantly higher in group HV than group LV. The catheter tip was visualized in the retroperitoneal space in 1\/16 and 2\/10 hemiabdomens in phases 1 and 2, respectively. Rescue analgesia was required in 3\/5 dogs during the postoperative period. The QL catheter placement technique appears feasible and may be included in a multimodal analgesic approach for dogs undergoing abdominal surgeries.<\/jats:p>","DOI":"10.3390\/vetsci11100472","type":"journal-article","created":{"date-parts":[[2024,10,2]],"date-time":"2024-10-02T03:57:08Z","timestamp":1727841428000},"page":"472","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Description and Outcomes of an Ultrasound-Guided Technique for Catheter Placement in the Canine Quadratus Lumborum Plane: A Cadaveric Tomographic Study and Clinical Case Series"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4375-8407","authenticated-orcid":false,"given":"Massimiliano","family":"Degani","sequence":"first","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2314-9794","authenticated-orcid":false,"given":"G\u00e9raldine","family":"Bolen","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Talarico","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9212-817X","authenticated-orcid":false,"given":"St\u00e9phanie","family":"No\u00ebl","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-7706-2502","authenticated-orcid":false,"given":"Kris","family":"Gommeren","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-7260-3022","authenticated-orcid":false,"given":"Chiara","family":"Di Franco","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, University of Pisa, 56122 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3404-2757","authenticated-orcid":false,"given":"Charlotte","family":"Sandersen","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences, Faculty of Veterinary Medicine, Fundamental and Applied Research for Animals & Health (FARAH), University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Reid, M., Campoy, L., and Fischer, B.
