ABSTRACT
In pediatric cardiac critical care, patients often require specific anesthesia and sedation considerations due to unique physiological vulnerabilities. This study assessed the incidence of propofol-related infusion syndrome (PRIS) in Pediatric Cardiac Intensive Care Unit (PCICU) patients receiving continuous propofol infusion for non-procedural sedation. We conducted a retrospective review of post-operative congenital heart disease patients < 18 years admitted to the PCICU from 1/1/2000-9/30/2024, who received continuous propofol infusions ≥ 12 hours and/or ≥ 2.4 mg/kg/hour. The primary outcome was the incidence of PRIS. Secondary outcomes included intensive care unit (ICU) length of stay and survival to hospital discharge. Statistical analyses included chi-square tests and the Kruskal-Wallis test, stratified by physiological complexity (single vs. double ventricle) and surgical mortality risk scores (The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery [STAT] score). A total of 641 patients were included. No statistically significant differences in propofol characteristics were found across physiologic or surgical risk groups. The median infusion rate was 1.2 mg/kg/hour, with a median duration of 22.7 hours. No cases of PRIS occurred. Survival to hospital discharge was 97%. The median ICU length of stay was 7.1 days. In this single center, retrospective study of post-operative congenital heart disease patients, continuous propofol infusion was not associated with any cases of PRIS. These findings support the cautious use of propofol in pediatric cardiac critical care. Further prospective studies are needed to evaluate safety across the heterogenous congenital heart disease population, including those with single ventricle physiology.
