Background Acute kidney injury (AKI) is a common complication after pediatric cardiac surgery and is associated with worse outcomes. Ibuprofen is widely used in the perioperative period and can affect kidney function in children. However, the association between ibuprofen exposure and AKI after pediatric cardiac surgery has not been determined yet.Methods In this retrospective cohort study, children undergoing cardiac surgery with cardiopulmonary bypass were studied. Exposure was defined as given ibuprofen in the first 7 days after surgery. Postoperative AKI was diagnosed using the KDIGO criteria. A multivariable Cox regression model was used to assess the association between ibuprofen exposure and postoperative AKI by taking ibuprofen as a time-varying covariate.Results Among 1,112 included children, 198 of them (17.8%) experienced AKI. In total, 396 children (35.6%) were exposed to ibuprofen. AKI occurred less frequently among children who were administered ibuprofen than among those who were not (46 of 396 [11.6%] vs. 152 of 716 [21.2%], p

Abstract Background The remarkable advancements in surgical techniques over recent years have shifted the clinical focus from merely reducing mortality to enhancing the quality of postoperative recovery. The duration of a patient’s hospital stay serves as a crucial indicator in evaluating postoperative recovery and surgical outcomes. This study aims to identify predictors of the length of hospital stay for children who have undergone corrective surgery for Ebstein Anomaly (EA). Methods We conducted a retrospective cohort study on children (under 18 years of age) diagnosed with EA who were admitted for corrective surgery between January 2009 and November 2021 at Fuwai Hospital. The primary outcome was the Time to Hospital Discharge (THD). Cox proportional hazard models were utilized to identify predictors of THD. In the context of time-to-event analysis, discharge was considered an event. In cases where death occurred before discharge, it was defined as an extended THD, input as 100 days (exceeding the longest observed THD), and considered as a non-event. Results A total of 270 children were included in this study, out of which three died in the hospital. Following the Cox proportional hazard analysis, six predictors of THD were identified. The hazard ratios and corresponding 95% confidence intervals were as follows: age, 1.030(1.005,1.055); C/R > 0.65, 0.507(0.364,0.707); Carpentier type C or D, 0.578(0.429,0.779); CPB time, 0.995(0.991,0.998); dexamethasone, 1.373(1.051,1.795); and transfusion, 0.680(0.529,0.875). The children were categorized into three groups based on the quartile of THD. Compared to children in the ≤ 6 days group, those in the ≥ 11 days group were associated with a higher incidence of adverse outcomes. Additionally, the duration of mechanical ventilation and ICU stay, as well as hospital costs, were significantly higher in this group. Conclusion We identified six predictors of THD for children undergoing corrective surgery for EA. Clinicians can utilize these variables to optimize perioperative management strategies, reduce adverse complications, improve postoperative recovery, and reduce unnecessary medical expenses.

Abstract Background The Enhanced Recovery After Cardiac Surgery (ERACS) programs are comprehensive multidisciplinary interventions to improve patients’ recovery. The application of the ERAS principle in pediatric patients has not been identified completely. Methods This study is a multicenter, stepwise design, cluster randomized controlled trial. 3030 patients presenting during control and intervention periods are eligible if they are aged from 28 days to 6 years old and awaiting elective correction surgery of congenital heart disease with cardiopulmonary bypass. 5 centers are randomly assigned to staggered start dates for one-way crossover from the control phase to the intervention phase. In the intervention periods, patients will receive a bundle strategy including preoperative, intraoperative, and postoperative approaches. During the control phase, patients receive the usual care. The primary outcome consists of major adverse cardiac and cerebrovascular events (MACCEs), postoperative pulmonary complications (PPCs), and acute kidney injury (AKI). Discussion This study aims to explore whether the bundle of ERAS measurements could improve patients’ recovery in congenital heart surgery. Trial registration http://www.clinicaltrials.gov .

Abstract Background Tetralogy of Fallot (TOF) is a common cyanotic congenital heart malformation that carries a high risk of right-to-left shunting. Anemia is characterized by decreased hemoglobin (Hb) levels that can affect tissue oxygen delivery and impact postoperative recovery in patients. Chronic hypoxia caused by right-to-left shunting of TOF could lead to compensatory increases in Hb to maintain systemic oxygen balance. This study aims to investigate whether preoperative Hb and blood oxygen saturation (SpO2) can predict adverse outcomes in children undergoing corrective surgery for TOF. Methods This retrospective study included patients under 18 years of age who underwent corrective surgery for TOF at Fuwai Hospital between January 2016 and December 2018. Adverse outcomes, including in-hospital death, extracorporeal membrane oxygenation implantation, ICU stay > 30 days, and severe complications, were considered as the primary outcome. Univariable and multivariable logistic analyses were performed to identify independent risk factors for adverse outcomes. Propensity score-matched (PSM) analysis was also conducted to minimize the confounding factors. Results A total of 596 children were included in the study, of which 64 (10.7%) experienced adverse outcomes. Hb*SpO2

Purpose: This study sought to explore the effect of intraoperative mean blood glucose levels and variability on postoperative acute kidney injury (AKI) in children undergoing congenital cardiac surgery. Methods: We conducted a prospective nested case-control study in children (age< 18 years) undergoing congenital heart surgery with cardiopulmonary bypass (CPB) at the Fuwai Hospital between April 01, 2022 and July 30, 2022. Cases were individuals who developed AKI within the first postoperative 7 days (AKI group) and controls were those without AKI (Non-AKI group) according to KDIGO criteria. AKI and Non-AKI groups unmatched and 1:1 matched by age, sex, and baseline serum creatinine were separately analyzed. Multivariate logistic and conditional logistic regressions were used to assess the associations between blood glucose variables and AKI. Results: 688 consecutively approached patients were included in the final analysis. On multivariate analysis, intra-CPB (adjusted odds ratio [OR] 0.802; 95% confidence interval [CI], 0.706 to 0.912; p = 0.001) and post-CPB (adjusted OR 0.830; 95% CI, 0.744 to 0.925; p = 0.001) blood glucose levels were associated with postoperative AKI. There were no significant differences in pre-CPB blood glucose (adjusted OR 0.926; 95% CI, 0.759 to 1.129; p = 0.446) or intraoperative glycemic fluctuations (adjusted OR 0.905; 95% CI, 0.723 to 1.132; p = 0.382) between AKI and Non-AKI groups. Results based on matched cases and controls were consistent with those from the unmatched analyses. Conclusion: Higher intraoperative blood glucose levels during and after CPB were protective factors against post- operative AKI in pediatric patients after congenital heart surgery.
