Background: Ultrafast-track extubation after cardiac surgery my facilitate rapid recovery. However, the overall risk-benefit is still debatable. The objective of this study was to report the effect of ultrafast-track extubation in pediatric patients undergoing cardiac surgery. Methods: This is a retrospective study that included 260 patients who had surgery for congenital heart diseases between 2015 and 2019. Patients were divided into two groups. Group A included patients who had ultrafast-track extubation protocol (n = 140), and group B was the conventional anesthesia group (n = 120). Results: The mean age was 3.68 ± 2.1 and 3.8 ± 1.6 years for groups A and B, respectively (p= 0.08). The total operative time was higher in group A (326± 18.15 vs. 274.6±28.1 minutes; p
