Programmed Intermittent Bolus Regimen for Erector Spinae Plane Blocks in Children: A Retrospective Review of a Single-Institution Experience

With few published reports on erector spinae plane block use in children, limited guidance on perioperative local anesthetic dosing exists. We present a series of 22 patients who received erector spinae plane catheters with programmed intermittent bolus for various surgeries. Median loading dose of 0.4 mL/kg (interquartile range [IQR], 0.1 mL/kg) ropivacaine 0.5%, intraoperative bolus of 0.3 mL/kg/h (IQR, 0.1 mL/kg) ropivacaine 0.2%, and a postoperative programmed intermittent bolus regimen of maximum 0.6 mg/kg/h resulted in highest pain scores on postoperative day 1 with a median score of 1.7 of 10 (IQR, 1.8) and highest morphine equivalents consumed on postoperative day 2 with a median score of 0.16 mg/kg up to 120 hours after surgery.
