To assess the feasibility of ultrasound (US) in visualizing the lateral femoral cutaneous nerve (LFCN) in a cadaver and 8 volunteers.
Ultrasound and US-guided dye injection was performed in 1 cadaver to show the feasibility of detecting the LFCN. We then performed US in 8 volunteers to assess position of the nerve in respect to the anterior iliac spine. We subsequently performed US-guided anesthetic block of the LFCN on both sides with 0.3 mL local anesthetic. Success rate, time to maximum peak blockade, and duration of blockade were noted.
Ultrasound allowed visualization of the LFCN in the cadaveric specimen on both sides and in all but 1 volunteer. Ultrasound-guided block of the LFCN was successful in all but 1 volunteer. The mean distance of LFCN from the anterior iliac spine was 2.9 cm on the right side and 2.8 cm on the left side. The mean duration of the block was 4.4 hours.
Ultrasound enables visualization of the LFCN in a cadaver and in volunteers. Ultrasound-guided injection successfully blocked the LFCN.
评估超声(US)在尸体及8名志愿者中显示股外侧皮神经(LFCN)的可行性。
对1具尸体进行超声及超声引导下染料注射,以显示检测LFCN的可行性。然后对8名志愿者进行超声检查,以评估神经相对于髂前上棘的位置。随后在双侧对LFCN进行超声引导下麻醉阻滞,注射0.3 mL局部麻醉剂。记录成功率、达到最大阻滞峰值的时间和阻滞持续时间。
超声能够在尸体标本双侧及除1名志愿者外的所有志愿者中显示LFCN。超声引导下LFCN阻滞除1名志愿者外均成功。LFCN距髂前上棘的平均距离右侧为2.9 cm,左侧为2.8 cm。阻滞的平均持续时间为4.4小时。
超声能够在尸体及志愿者中显示LFCN。超声引导下注射成功阻滞了LFCN。
