Fast-tracking with continuous thoracic epidural analgesia in paediatric congenital heart surgeries: an institutional experience

Objective: To assess the success of fast-tracking in infants and small children undergoing paediatric cardiac surgery under general anaesthesia with continuous thoracic epidural analgesia (TEA).

Methodology: It is a retrospective study at a tertiary care hospital. A total of 461 children, aged 12 years or younger, were operated for congenital heart disease over a 2-year period from January 2018 to December 2019. After the exclusion of 71 patients, data from the remaining 390 patients were analysed.

Measurements and main results: The median time for extubation after intensive care unit admission was 2 h and 25 min (0-20 h). Extubation within 6 h was achieved in 215 patients (~ 55%). Patients in the early extubation group had significantly shorter hospital stay (4.1 ± 2.3 vs 6.9 ± 3.9 days, p = 0.004) than patients in the ventilated group. Reintubation was required in 27 (6.9%) patients. Thirteen patients died postoperatively on ventilator. Patients with low nadir temperature intraoperatively and cardiopulmonary bypass time > 90 min significantly predicted failure in fast-tracking with an odds ratio (OR) = 1.27; CI: 1.18-1.38 and OR = 2.3; CI: 1.8-2.96 respectively. The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery Congenital Heart Surgery mortality score, younger age, Down syndrome and high vasopressor inotropic score did not adversely affect early extubation, contrary to contemporary concerns.

Conclusions: A multimodal approach for perioperative pain relief and sedation consisting of propofol and dexmedetomidine infusion along with TEA ensures early extubation in 59% of the cases undergoing paediatric cardiac surgery. Our data suggests that fast-tracking is feasible with safe and superior outcomes in a subset of appropriate patients undergoing paediatric cardiac surgery.
