A total of twenty-three female dogs were included. Dogs were randomly assigned to receive a bilateral QLBLQL-T, performed either with 0.3 mL kg\u22121 ropivacaine 0.5% [group QLB0.5% (n = 8)] or with ropivacaine 0.33% [group QLB0.33% (n = 8)] or a fentanyl-based protocol [group No-QLB (n = 7)]. Dogs were premedicated intravenously (IV) with fentanyl 5 mcg kg\u22121, general anesthesia was induced IV with propofol and maintained with sevoflurane. Invasive mean arterial pressure (MAP) values were recorded five minutes before and five minutes after performing the QLBLQL-T. The short-form of the Glasgow composite measure pain scale was used every hour after extubation, and methadone 0.2 mg kg\u22121 was administered IV when pain score was \u22655\/24. Kolmogorov\u2013Smirnov test, ANOVA test combined with Tukey post hoc test, Student\u2019s T-test and Chi-square test were used to analyze data; p &lt; 0.05. Time from QLBLQL-T to the first rescue analgesia was significantly longer in QLB0.5% than in group QLB0.33% and No-QLB. MAP pre- and post-block decreased significantly only in group QLB0.33%.<\/jats:p>","DOI":"10.3390\/ani13233604","type":"journal-article","created":{"date-parts":[[2023,11,22]],"date-time":"2023-11-22T03:54:37Z","timestamp":1700625277000},"page":"3604","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Postoperative Analgesic Effect of Bilateral Quadratus Lumborum Block (QLB) for Canine Laparoscopic Ovariectomy: Comparison of Two Concentrations of Ropivacaine"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4375-8407","authenticated-orcid":false,"given":"Massimiliano","family":"Degani","sequence":"first","affiliation":[{"name":"Department of Veterinary Sciences, Veterinary Teaching Hospital \u201cMario Modenato\u201d, University of Pisa, 56122 Pisa, Italy"},{"name":"Clinical Department for Companion Animal Sciences, Faculty of Veterinary Medicine, 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, Veterinary Teaching Hospital \u201cMario Modenato\u201d, University of Pisa, 56122 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3736-0950","authenticated-orcid":false,"given":"Hamaseh","family":"Tayari","sequence":"additional","affiliation":[{"name":"Southern Counties Veterinary Specialists (SCVS), Forest Corner Farm, Hangersley, Ringwood, Hampshire BH24 3JW, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5378-1451","authenticated-orcid":false,"given":"Aida","family":"Fages Carc\u00e9les","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, Veterinary Teaching Hospital \u201cMario Modenato\u201d, University of Pisa, 56122 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giacomo","family":"Fig\u00e0 Talamanca","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, Veterinary Teaching Hospital \u201cMario Modenato\u201d, 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":"Clinical Department for Companion Animal Sciences, Faculty of Veterinary Medicine, University of Li\u00e8ge, 4000 Li\u00e8ge, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6949-4414","authenticated-orcid":false,"given":"Angela","family":"Briganti","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, Veterinary Teaching Hospital \u201cMario Modenato\u201d, University of Pisa, 56122 Pisa, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Fern\u00e1ndez-Mart\u00edn, S., Vali\u00f1o-Cultelli, V., and Gonz\u00e1lez-Cantalapiedra, A.
