OBJECTIVE
To develop and describe an acoustic window to access and inject the retrobulbar region in donkey cadavers.
STUDY DESIGN
Prospective cadaveric experimental study.
ANIMALS
A total of 14 donkey cadaver heads.
METHODS
Ultrasound landmarks for retrobulbar injection were identified by dissection of two cadavers. Ultrasound-guided retrobulbar injection of 3, 6 and 9 mL of contrast-lidocaine mixture (1:1) were evaluated using computed tomography (CT) in 12 cadavers for needle position and spread of injectate into the extraocular muscle cone.
RESULTS
Real-time visualization of needle, extraocular muscle cone and optic nerve enabled successful intraconal instillation of injectate, as documented on CT images.
CONCLUSIONS AND CLINICAL RELEVANCE
Ultrasound-guided retrobulbar injections in cadaver donkeys provided adequate infiltration of the intraconal space.
目的
开发并描述一种用于进入和注射家驴尸体球后区域的声窗。
研究设计
前瞻性尸体实验研究。
动物
共 14 个头骨。
方法
通过对两具尸体进行解剖，确定了超声引导下球后注射的超声标志点。使用 CT 评估了 12 具尸体中 3、6 和 9 mL 对比-利多卡因混合物（1:1）的超声引导下球后注射，以评估针的位置和注射物在眼外肌锥内的扩散情况。
结果
实时可视化的针、眼外肌锥和视神经使注射物能够成功地注入眶内，这在 CT 图像上得到了证实。
结论和临床相关性
在尸体家驴中进行的超声引导下球后注射为眶内间隙提供了充分的浸润。
