Lesser occipital nerve block
occipital nerve block
Due to the limitation of resolution of the ultrasound probe, the superficial cervical plexus was blocked to block the lesser occipital nerve. The child lay in a supine position with the head tilted to the opposite side. The superficial cervical plexus was positioned ipsilateral to the superficial cervical plexus and then punctured in-plane from the lateral side. The superficial cervical plexus (including the lesser occipital nerve) was located at the deep surface of the lateral border of the sternocleidomastoid muscle. Then, 0.1 ml/kg local anesthetic was injected, and the local anesthetic was observed to be spread in the interstitial space below the sternocleidomastoid muscle (Fig. Lesser occipital nerve block
