Regional nerve blocks have been shown to decrease general anesthetic drug requirements and improve pain management in patients undergoing surgery. Regional nerve blocks are used routinely in patients undergoing oral surgery, such as dental extractions. There is little published information regarding the efficacy of feline maxillary and infraorbital nerve blocks. The goal of the study was to compare injectate distributions of the infraorbital foramen and percutaneous maxillary nerve block techniques in feline cadavers using a combined dye and radiopaque contrast media solution to simulate an injection. There was no significant difference in length of stained nerve between the two different techniques. It was not necessary to advance the needle into the infraorbital canal to achieve effective staining of the maxillary nerve. There was no significant difference in injectate distribution between two different injectate volumes, 0.2 and 0.4 ml, indicating that the smaller volume injected at the infraorbital foramen resulted in adequate nerve staining.

局部神经阻滞已显示可降低全身麻醉药物的需求量，并改善手术患者的疼痛管理。局部神经阻滞通常用于接受口腔手术（例如拔牙）的患者。关于猫上颌和眶下神经阻滞疗效的公开信息很少。该研究的目的是比较使用染料和不透射线的造影剂溶液模拟注射的猫尸体中眶下孔和经皮上颌神经阻滞技术的注射分布。两种不同技术之间的神经染色长度没有显着差异。不必将针头推进到眶下管即可实现上颌神经的有效染色。
