OBJECTIVE The use of ultrasound (US) for localization of neural structures allows real-time visualization of anatomy; however, variability in the arrangement of structures has been observed. The impact of these variations on the performance and outcome of regional anesthetic techniques remains unclear. We discuss possible anatomic explanations and correlation with clinical observations. CASE REPORT We report limited spread of local anesthetic observed during the performance of a US-guided… CONTINUE READING
