An ultrasound (US)-guided ventral suprainguinal approach to block the femoral nerve (FN) within the iliopsoas muscle (IPM) has recently been described in dogs. The goal of the present study was to provide the operator with additional information to locate the FN within the IPM in dogs and cats using US.
The study was carried out in three phases: a dissection of the FN (phase 1); an in vivo US-assisted nerve study (phase 2), and an anatomical cross-sectional study (phase 3).
Nine healthy adult beagle dogs and nine healthy adult cats.
Dissections were performed to investigate the anatomical characteristics of the FN and its related structures in one dog and one cat. Ultrasound scans of the left and right FN were performed in eight dogs and eight cats. The FN diameter and the distance between the FN and the external iliac artery (EIA) in US images and in anatomical cryosections were measured.
The median FN diameter did not differ significantly between cats and dogs (1.1 mm versus 1.0 mm) or between the two techniques (US versus anatomical cross-sectional study) (1.1 mm versus 1.1 mm in dogs; 1.0 mm versus 1.1 mm in cats). The US and anatomical measurements of the median distances between the FN and EIA differed significantly between dogs and cats (8.2 mm versus 5.8 mm by US; 5.7 mm versus 4.8 mm in the anatomical study).
The distance between the EIA and FN is reproducible in beagle dogs and cats and can be used in locating the FN within the IPM.
最近有文献报道了一种在犬中采用超声引导下腹股沟上腹部入路阻滞髂腰肌内股神经（FN）的方法。本研究的目的是为操作人员提供更多信息，以便使用超声在犬和猫的髂腰肌内定位股神经。
本研究分三个阶段进行：股神经解剖（第一阶段）；体内超声辅助神经研究（第二阶段），以及解剖横断面研究（第三阶段）。
9只健康成年比格犬和9只健康成年猫。
对1只犬和1只猫进行解剖，以研究股神经及其相关结构的解剖特征。对8只犬和8只猫的左右股神经进行超声扫描。测量超声图像和解剖冷冻切片中股神经直径以及股神经与髂外动脉（EIA）之间的距离。
猫和犬之间的股神经直径中位数无显著差异（1.1毫米对1.0毫米），两种技术（超声与解剖横断面研究）之间也无显著差异（犬中分别为1.1毫米对1.1毫米；猫中为1.0毫米对1.1毫米）。犬和猫之间股神经与髂外动脉之间距离中位数的超声测量值和解剖测量值存在显著差异（超声测量分别为8.2毫米对5.8毫米；解剖研究中为5.7毫米对4.8毫米）。
在比格犬和猫中，髂外动脉与股神经之间的距离具有可重复性，可用于在髂腰肌内定位股神经。
