Evaluation of contrast-enhanced ultrasonography with Sonazoid ® in visualization of local anesthetic distribution in rectus sheath block: a prospective, clinical study

ConclusionSonazoid diluted 100-fold® was clearly visualized real-time, and the enhancement was sustained and measurable after RSB. Sonazoid® could potentially be used for the contrast agent of US-guided nerve block.
