BACKGROUND AND OBJECTIVES
The presence of neurovascular abnormalities may increase the risk of complications following regional anesthesia techniques. Use of conventional nerve localization methods may fail to detect such abnormalities and potentially result in block failure and/or unintentional neurovascular injury.
METHODS
We use 2 examples to illustrate this, and the concept that systematic use of a preprocedure ultrasound (US) scan may serve as an aid both for diagnosis of abnormal anatomy, and in planning the appropriate anesthetic technique.
RESULTS
Use of a preprocedure US scan helped to diagnose abnormal anatomy and assisted in planning a more appropriate anesthetic technique.
CONCLUSIONS
We believe that a systematic sonographic survey prior to regional anesthesia can be a valuable bedside screening tool to assess the suitability and challenges involved in performing US-guided peripheral nerve block.
背景与目的
神经血管异常的存在可能会增加区域麻醉技术后并发症的风险。使用传统的神经定位方法可能无法检测到此类异常，从而可能导致阻滞失败和/或意外的神经血管损伤。
方法
我们用2个例子来说明这一点，以及术前系统性使用超声（US）扫描可有助于诊断解剖结构异常和规划合适的麻醉技术这一概念。
结果
术前使用超声扫描有助于诊断解剖结构异常，并协助规划更合适的麻醉技术。
结论
我们认为，区域麻醉前进行系统性超声检查可成为一种有价值的床边筛查工具，以评估实施超声引导下外周神经阻滞的适用性和面临的挑战。
