Ultrasound-guided lower thoracic erector spinae block for postoperative analgesia in complex colorectal surgery in a pediatric patient.

The erector spinae plane (ESP) block is a relatively novel regional anesthetic technique first described in 2016. There are limited data regarding its use in pediatric surgeries although ESP blocks can likely be safely used to provide effective postoperative analgesia for major thoracic and abdominal surgeries, especially in cases where neuraxial anesthesia is contraindicated. In this report, we describe a case in which bilateral lower thoracic erector spinae plane blocks were performed in a pediatric patient with vertebral anomalies undergoing posterior sagittal anorectoplasty and reconstruction of cloacal malformation.
