Systemic Absorption of Lidocaine from Continuous Erector Spinae Plane Catheters After Congenital Cardiac Surgery: A Retrospective Study.
To examine postoperative serum lidocaine levels in patients with intermittent lidocaine bolus erector spinae plane block (ESPB) catheters after cardiac surgery with or without cardiopulmonary bypass (CPB). ⋯ Postoperative serum lidocaine concentrations did not appreciably differ due to CPB. Serum lidocaine concentrations did not reach near- toxic doses despite the presence of additional lidocaine in the cardioplegia. The results suggested that lidocaine for ESPBs after cardiac surgery is below systemic toxic range at the doses described.
