In veterinary medicine, the use of loco-regional anesthesia techniques is increasing. The block (QL) is an interfascial loco-regional technique that involves the release of local anesthetic (LA) between the and the (Pm) muscle. The study aims to evaluate the effect of the QL block on reducing the total amount of opioids in dogs undergoing pre-scrotal orchiectomy. A group of 36 dogs was enrolled in a randomized blinded study. The animals were divided into two groups: 18 in the experimental group (QL) and 18 in the control group (C). The QL group received 0.4 mL kg of ropivacaine 0.5% for each hemiabdomen (total amount of 3 mg kg of ropivacaine, 1.5 mg kg per side). The C group was brought into the operating room (OR) after receiving the same clipping as the QL group. In the intraoperative period, opioid consumption in the QL group was significantly lower than in the C group. No differences were found in the post-operative phase. No side effects were reported when performing the QL technique. The QL block performed at the level of L6 appears to be a valid approach to reducing opioid use in dogs undergoing orchidectomy with a pre-scrotal surgical approach.
在兽医学中，局部区域麻醉技术的应用正在增加。腰方肌阻滞（QL）是一种筋膜间局部区域技术，涉及在腰方肌和腰大肌（Pm）之间注射局部麻醉剂（LA）。本研究旨在评估QL阻滞对减少阴囊前睾丸切除术犬类阿片类药物总量的影响。一组36只犬参与了一项随机双盲研究。动物被分为两组：实验组（QL）18只和对照组（C）18只。QL组每侧半腹部接受0.4 mL/kg的0.5%罗哌卡因（罗哌卡因总量为3 mg/kg，每侧1.5 mg/kg）。C组在接受与QL组相同的剪毛处理后进入手术室（OR）。在术中，QL组的阿片类药物消耗量显著低于C组。术后阶段未发现差异。实施QL技术时未报告副作用。在L6水平进行的QL阻滞似乎是一种有效的方法，可以减少采用阴囊前手术方法进行睾丸切除术的犬类的阿片类药物使用量。
