Ultrasound Guided Posterior Tibial Nerve Block to Facilitate Foreign Body Removal in a School-Aged Child

摘要

Soft tissue foreign bodies are common chief complaints in the emergency department (ED). Ultrasound has been utilized for detecting foreign bodies, both radiopaque and non-radiopaque, and facilitating their removal from soft tissue.1 Point-of-care ultrasound (POCUS) offers ED providers a safe and efficient way to determine if a foreign body is present, perform precise 3-dimensional localization, and maintain visualization during removal.1 POCUS further enables the practitioner to determine if a foreign body has been removed in its entirety, as wood, thorns, and other objects often fragment with initial puncture and removal.2 Additionally, POCUS can be quickly performed, potentially resulting in a shortened ED length of stay. We report the case of a 9-year-old male who presented to the ED with recurrent foot infections.
