Bilateral single shot erector spinae plane block for pectus excavatum and pectus carinatum surgery in 2 pediatric patients.

Numerous publications have emerged on the application of erector spinae plane block in adult population. There are few reports of the use of this block in pediatric patients. The objective is to report 2 cases of adolescents, one diagnosed with pectus excavatum and the other one with pectus carinatum undergoing reconstructive surgery in which a bilateral single-shot erector spinae plane block was performed as an analgesic technique. The block was performed before surgery under general anesthesia in lateral decubitus position, guided by ultrasound using 20ml of 0.25% bupivacaine per side. After the surgery they were extubated and transferred to the Intensive Care Unit. During their postoperative period they had visual analogic scale values less than 4 and no long term narcotics were used during the intraoperative and postoperative period. Bilateral single shot erector spinae plane block was effective as an analgesic technique for the intraoperative and postoperative period in pectus excavatum and pectus carinatum surgery in adolescents.
