“…Existing techniques are based on measurements from fixed anatomical points, and are hence limited when applied to children of various ages (Hong et al, , Brasher et al, ). Only recently, clinical imaging studies have been conducted to provide new anatomical landmarks for different peripheral nerve blockades in children, with reference to their age‐related growth and anatomy (Dadure et al, , Suresh et al, , Mello et al, , Berniere et al, , Hong et al, ). Most landmarks, however, are yet to be standardized in infants and children, and furthermore, inconsistencies exist in the current descriptions of the surface landmarks used for nerve blockades in pediatric patients.…”
