This study is a prospective, randomized, non-blinded clinical trial examining the use of
paravertebral peripheral nerve block in the neonatal and infant populations. The primary aim
of this study is to determine the feasibility of studying whether a single-shot paravertebral
nerve block is effective in providing intraoperative and postoperative pain control in
infants undergoing a thoracotomy for coarctation of the aorta. This will be determined by
comparing consumption of narcotics, expressed as morphine equivalents, in the standard of
care and intervention groups.
