Objective: To evaluate the predictive value of 3 different risk stratification models including the risk adjustment in congenital heart surgery-1 (RACHS-1), Aristotle basic complexity (ABC), and Society of Thoracic Surgeons-European Association for cardiothoracic surgery congenital heart surgery mortality score (STAT) risk scoring system for death and major complications in patients after congenital heart surgeries. Methods: A total of 3 578 patients (age<18 years old) received surgery for congenital heart diseases from January to December 2015 in Fuwai hospital were enrolled, and the clinical data were retrospectively analyzed. The congenital heart disease patients were 1.7 (0.8, 4.5) years old, and the male accounted for 54.3% (1 943 cases).Death after surgery and major complications including use of extracorporeal membrane oxygenation, bedside thoracotomy, peritoneal dialysis for renal failure, bedside hemofiltration for renal failure, tracheotomy, reoperation for mediastinum infection, reoperation for heart in hospital were observed. The area under the receiver operating characteristic (ROC) curve was calculated to evaluate the predictive value for mortality after surgery and major complications with RACHS-1, ABC, and STAT risk scoring systems. Results: The mortality after surgery was 0.4% (14/3 578) , and the rate of major complications was 3.2% (113/3 578) . For mortality after surgery, areas under the ROC curve were 0.682 (95%CI 0.570-0.795, P=0.002), 0.722 (95%CI 0.612-0.832, P<0.001), and 0.753 (95%CI 0.659-0.847, P<0.001) with RACHS-1, ABC and STAT risk scoring systems, respectively. For major complications, areas under the ROC curve were 0.709 (95%CI 0.667-0.751, P<0.001), 0.743 (95%CI 0.702-0.784, P<0.001), and 0.731 (95%CI 0.693-0.770, P<0.001) with RACHS-1, ABC and STAT risk scoring systems, respectively. Conclusion: STAT risk scoring system is superior to RACHS-1 and ABC risk scoring systems on predicting death after surgery, and ABC risk scoring system is superior to RACHS-1 and STAT risk scoring systems on predicting major complications in Chinese patients with congenital heart disease in the single center.

OBJECTIVES:Postoperative fluid overload is common in children after cardiac surgery, especially for those with right ventricular outflow tract obstruction, which is associated with poor outcomes. This study was conducted to investigate whether early peritoneal dialysis (PD) was associated with improved outcomes in these children at high risk of fluid overload.METHODS:Between January 2010 and January 2015, a total of 2555 consecutive patients with right ventricular outflow tract obstruction underwent anatomical repair. Using empirical risk evaluation, 219 patients at high risk of fluid overload were identified. A propensity score matching was performed to correct the selection bias and identify the comparable patient groups: the early PD group, in whom PD was initiated within 6 h of admission in paediatric ICU, and the control group, without early PD. The mechanical ventilation time, vasoactive-inotropic score and time to negative fluid balance were compared in 45 matched patient pairs (totally 90).RESULTS:After propensity matching, there were no statistically significant differences between the 2 groups in terms of demographics and preoperative characteristics. The early PD group had shorter mechanical ventilation time [median 49 h, interquartile range (IQR) 31-97 h vs median 76 h, IQR 55-166 h; P < 0.01]; lower vasoactive-inotropic score (median 17, IQR 16-21 vs median 22, IQR 18-26; P < 0.01); shorter duration of inotrope requirement (median 7 days, IQR 6-9 days vs median 8 days, IQR 7-13 days; P < 0.01); shorter time to negative fluid balance (median 20 h, IQR 13-34 h, vs median 48 h, IQR 40-74 h; P < 0.01) and a higher rate of negative fluid balance at 24 h (69% vs 29%, P < 0.01).CONCLUSIONS:When compared with the control group, the early PD group showed shorter mechanical ventilation time, less inotropic requirement and lower time to attain negative fluid balance. On the basis of our empirical risk-evaluation practice, early PD could improve immediate postoperative recovery in children with right ventricular outflow tract obstruction.
