摘要

Ultrasound-Guided peripheral nerve blocks (PNBs) can offer many benefits, but their performance requires excellent knowledge of the related clinical anatomy and confidence with obtaining reproducible ultrasound images while simultaneously handling the probe and needle. Unfortunately, there has not yet been a set of standard training modalities developed to improve clinical performance with ultrasound-guided PNBs. Although underutilized, cadavers are useful tools for practical training in regional anesthesia. Utilizing cadavers could increase block-related anatomical knowledge and confidence in performing these blocks, both of which may ultimately enhance the learning of ultrasound-guided PNBs. Specific elements that could benefit from teaching with a cadaver model include probe handling on irregular surfaces (e.g., supraclavicular region), accurate probe-needle alignment to enable clear visibility of the entire needle, and needle tracking to the target nerve structure. While not every medical school will have the accessibility or desire to use cadavers for training with nerve block techniques, this medium may be very suitable for large group teaching sessions.
