Regional Anesthesia for Cardiothoracic Enhanced Recovery (RACER) Study

Bilateral ESPBs will be placed after anesthesia induction in eligible and consented patients who are undergoing a sternotomy for congenital heart repair. Patients will receive a local anesthetic agent through each catheter prior to surgery start. If possible, levels of the local anesthetic will be measured during the case. After surgery, patients will be admitted to the CVICU and extubation will be managed by the CVICU team. The ESPB group will have an automatic, alternating side boluses of the local anesthetic started through their nerve block catheters. Levels of the local anesthetic will be measured at intervals.
