Objectives: To compare the effects of the QLB with those of ScE in cats undergoing ovariectomies. Methods: Feral cats undergoing ovariectomy were premedicated with dexmedetomidine (20 \u03bcg kg\u22121) and methadone (0.2 mg kg\u22121) intramuscularly. Anaesthesia was induced with 2\u20134 mg kg\u22121 of propofol intravenously and maintained with isoflurane in oxygen. The cats were randomly allocated to the groups QLB (bilateral QLB with 0.4 mL kg\u22121 of 0.25% bupivacaine) and ScE (0.3 mL kg\u22121 of 0.25% bupivacaine). Hemodynamic data and analgesia rescue were collected at four intraoperative periods. The pain scale and motor block were assessed in both groups during the postoperative period. Results: The ScE results in increased hypotension, prolonged extubation time, and higher postoperative motor block than the QLB (p &lt; 0.05). The QLB and ScE groups required a similar number of intraoperative rescues and presented the same postoperative pain scale classification. Conclusions: The QLB with 0.25% bupivacaine is a potential alternative to ScE with 0.25% bupivacaine in perioperative pain management in elective cat ovariectomy. The QLB promoted less hypotension and postoperative motor block when compared with the ScE group.<\/jats:p>","DOI":"10.3390\/vetsci11010025","type":"journal-article","created":{"date-parts":[[2024,1,8]],"date-time":"2024-01-08T07:59:20Z","timestamp":1704700760000},"page":"25","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Comparison between Bilateral Ultrasound-Guided Quadratus Lumborum Block and Sacrococcygeal Epidural in Cats Undergoing Ovariectomy"],"prefix":"10.3390","volume":"11","author":[{"given":"Jos\u00e9 Diogo","family":"dos-Santos","sequence":"first","affiliation":[{"name":"VetOeiras\u2014Veterinary Hospital, 2780-114 Oeiras, Portugal"},{"name":"Department of Veterinary Science, University Lus\u00f3fona, 1749-024 Lisbon, Portugal"},{"name":"CECAV\u2014Animal and Veterinary Research Centre UTAD, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), Portugal Department of Veterinary Science, University Lus\u00f3fona, 1300-477 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0464-7771","authenticated-orcid":false,"given":"M\u00e1rio","family":"Ginja","sequence":"additional","affiliation":[{"name":"CECAV\u2014Animal and Veterinary Research Centre UTAD, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), Portugal Department of Veterinary Science, University Lus\u00f3fona, 1300-477 Lisbon, Portugal"},{"name":"CITAB\u2014Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Jo\u00e3o","family":"Martins","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, University Lus\u00f3fona, 1749-024 Lisbon, Portugal"},{"name":"CECAV\u2014Animal and Veterinary Research Centre UTAD, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), Portugal Department of Veterinary Science, University Lus\u00f3fona, 1300-477 Lisbon, Portugal"},{"name":"CITAB\u2014Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"Patr\u00edcia","family":"Cabral","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, University Lus\u00f3fona, 1749-024 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9842-1759","authenticated-orcid":false,"given":"Sofia","family":"Alves-Pimenta","sequence":"additional","affiliation":[{"name":"CECAV\u2014Animal and Veterinary Research Centre UTAD, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), Portugal Department of Veterinary Science, University Lus\u00f3fona, 1300-477 Lisbon, Portugal"},{"name":"CITAB\u2014Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]},{"given":"L\u00e9nio","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"Department of Veterinary Science, University Lus\u00f3fona, 1749-024 Lisbon, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0901-7269","authenticated-orcid":false,"given":"Pablo E.","family":"Otero","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology and Pain Management, Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, Buenos Aires C1427CWN CABA, Argentina"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4879-8624","authenticated-orcid":false,"given":"Bruno","family":"Cola\u00e7o","sequence":"additional","affiliation":[{"name":"CECAV\u2014Animal and Veterinary Research Centre UTAD, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Sciences (AL4AnimalS), Portugal Department of Veterinary Science, University Lus\u00f3fona, 1300-477 Lisbon, Portugal"},{"name":"CITAB\u2014Centre for the Research and Technology of Agro-Environmental and Biological Sciences, University of Tr\u00e1s-os-Montes and Alto Douro, 5000-801 Vila Real, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2024,1,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"214","DOI":"10.1016\/j.tvjl.2007.10.011","article-title":"The effect of local anaesthesia on anaesthetic requirements for feline ovariectomy","volume":"178","author":"Zilberstein","year":"2008","journal-title":"Vet.
