Enhancing Recovery in Congenital Cardiac Surgery.

Abstract Background The benefits of a comprehensive enhanced recovery after surgery (ERAS®) program for the congenital heart disease population are largely unknown. We evaluated adherence and outcomes following a recently implemented enhanced recovery program (ERP) in congenital cardiac surgery. Methods Patients undergoing elective surgery for simple and moderately complex congenital cardiac surgery followed institutional ERP guidelines since 10/2018. Adherence to guidelines over a 12-month period (P2) was compared to implementation data (P1:5 months). The association of outcomes with continuous time was estimated using linear regression. Results Among 559 patients (representing 40% of the cardiac surgical volume) following the ERP over a period of 17 months, no differences in patient characteristics were observed between periods, except higher incidence of prior operations in P2. Adherence to many aspects of guidelines improved from P1 to P2. Notably, operating room extubation: 27% in P2 vs.16% in P1, p=0.006; decrease in median ventilation time: 6.0-hrs (IQR 0-9.2) in P2 vs. 7.6-hrs (IQR 3.8-12.3) in P1, p=0.002. In addition, there was a reduction in opioids, reported as oral morphine equivalents (OME), most significant for intraoperative OME: 5.00 mg/kg (3.11–7.60) in P2 vs. 6.05 mg/kg (3.77–9.78) in P1, p=0.001. There was no difference in overall intensive care unit (ICU) and postoperative length of stay except in lower risk surgeries. Surgical outcomes were similar in the two periods. Conclusions An enhanced recovery program reduced the use of opioids, led to more OR extubation and reduced mechanical ventilation duration in patients undergoing congenital cardiac surgery.
