To develop and assess the feasibility, as a diagnostic block, of an ultrasound-guided lateral pericapsular hip desensitization (L-PHD) technique in dogs.
Prospective, randomized, anatomical and feasibility study.
A total of 11 canine cadavers and eight adult dogs scheduled for acetabular surgical denervation.
After studying the ultrasound anatomy of the lateral aspect of the gluteal region and determining an acoustic window to perform an ultrasound-guided L-PHD in three canine cadavers, the right and left hemipelves of eight canine cadavers were injected in the interfascial plane located lateral (L-PHD group) or medial (L-PHD group) to the deep gluteal muscle, with 0.05 mL kg of dye per hip on each cadaver. The staining of the pericapsular nerves was assessed by anatomical dissection. Then, the L-PHD was performed using 2% lidocaine as a diagnostic block in dogs scheduled for acetabular surgical denervation. Positive predictive value (PPV) was calculated for those animals who had favorable outcomes after acetabular surgical denervation.
The ultrasound-guided L-PHD and L-PHD could be performed by inserting the needle lateral and medial to the deep gluteal muscle. Ultrasound-guided L-PHD stained the cranial gluteal nerve and its muscular branches in all injections and partially stained the lumbosacral trunk in two out of eight cadavers. The L-PHD selectively stained the articular branches of the cranial gluteal nerve in all but one cadaver. The PPV for L-PHD successful test prediction was 85.7% (95% confidence interval: 48.6% to 98.6%).
and clinical significance Ultrasound-guided L-PHD using 0.05 mL kg of dye selectively stained the articular branches of the cranial gluteal nerve in canine cadavers. The L-PHD technique is feasible and could be used as a diagnostic block before acetabular surgical denervation in dogs.
开发并评估超声引导髋关节外侧囊周去敏化（L-PHD）技术作为诊断性阻滞的可行性，该技术在犬中应用。
前瞻性、随机、解剖学和可行性研究。
共 11 具犬尸体和 8 只成年犬，计划进行髋臼手术神经切断术。
在研究了臀部外侧的超声解剖结构，并在 3 具犬尸体上确定了一个声窗，以进行超声引导的 L-PHD 后，对 8 具犬尸体的左右半骨盆在深臀肌的外侧（L-PHD 组）或内侧（L-PHD 组）平面进行注射，每侧每只犬注射 0.05 mL·kg 的染料。通过解剖学解剖评估关节囊神经的染色情况。然后，在计划进行髋臼手术神经切断术的犬中，使用 2%利多卡因进行 L-PHD 作为诊断性阻滞。对髋臼手术神经切断术效果良好的动物计算阳性预测值（PPV）。
超声引导的 L-PHD 和 L-PHD 可以通过将针插入深臀肌的外侧和内侧来进行。超声引导的 L-PHD 在所有注射中均能染色颅臀神经及其肌支，并在 8 具尸体中的 2 具中部分染色腰荐干。L-PHD 选择性地在除 1 具尸体外的所有尸体中染色颅臀神经的关节支。L-PHD 成功测试预测的 PPV 为 85.7%（95%置信区间：48.6%~98.6%）。
超声引导的 L-PHD 使用 0.05 mL·kg 的染料选择性地在犬尸体中染色颅臀神经的关节支。L-PHD 技术是可行的，可作为犬髋臼手术神经切断术的诊断性阻滞。
