Local anesthetic toxicity following erector spinae plane block in a neonate: A case report.

A 6-day-old, 4.0 kg neonate presented with intestinal malrotation, necessitating laparotomy. Intra-operatively, an ultrasound-guided erector spinae plane block was performed under general anesthesia with administration of 1 mg/kg levobupivacaine.

Successful use of ultrasound-guided caudal catheter in a child with a very low termination of dural sac and Opitz-GBBB syndrome: a case report.

We report a 2-year-old patient with Opitz-GBBB syndrome scheduled for a posterior sagittal anorectoplasty (PSARP). The ultrasound scan revealed the inferior end of dural sac just below sacrococcygeal membrane, although the patient had previously two successful caudal epidural blocks. Consequently, the epidural catheter was inserted under a real-time ultrasound guidance without dural puncture.

Infraclavicular brachial plexus block for the management of inadvertent intraarterial drug administration after arterial insertion of a venous cannula during ultrasound-guided venous cannulation.

This case report documents the inadvertent placement of an arterial cannula despite using realtime ultrasound to insert a peripheral venous cannula in a child with difficult venous access. The resultant limb ischemia was treated with an infraclavicular ultrasound-guided brachial plexus block as sympatholytic treatment.

Dorsal penile nerve block for male pediatric circumcision--randomized comparison of ultrasound-guided vs anatomical landmark technique.

Background: Dorsal penile nerve block (DPNB) is a commonly performed regional anesthetic technique for male circumcision. Traditionally, DPNB is based on an anatomical landmark technique. Recently, an ultrasound-guided technique for DPNB has been described.
