Subjects were enrolled between April 1988 and February 1992. Eligibility criteria and trial methods for the earlier evaluations were previously described.7 (link)–10 (link) Admission criteria included a diagnosis of d-TGA with intact ventricular septum (IVS) or ventricular septal defect (VSD), scheduled repair by three months of age, and coronary-artery anatomy suitable for the ASO. Exclusion criteria were birth weight <2.5 kg, a recognizable syndrome of congenital anomalies, an associated extra-cardiac anomaly of greater than minor severity, previous cardiac surgery, or associated cardiovascular anomalies requiring aortic arch reconstruction or additional open surgical procedures.
Infants were randomly assigned to a predominant support strategy of DHCA or LFBP during hypothermic cardiopulmonary bypass using an alpha-stat pH strategy and crystalloid hemodilution to a hematocrit of approximately 20%. Ultrafiltration was not utilized. Postoperative management typically included the use of continuous infusions of neuromuscular blockade and high-dose Fentanyl for analgesia, with a median duration of mechanical ventilation of 4 days.12 (link) Randomization was stratified by septal status (IVS, VSD) and surgeon. This study was approved by the Institutional Review Board and conducted in accordance with institutional guidelines. Parents of adolescents provided informed consent, and adolescents provided assent.
We recruited a referent group of adolescents for the MRI studies because there is no nationally representative standardization sample for brain MRIs. This group was also used as referents for test scores for which national norms are unavailable. Criteria for the referent group were adapted from those used in the NIH MRI study of normal brain development.13 (link) Because the goal of that study is to provide reference ranges for brain development, children with known risk factors for brain disorders are excluded (e.g., intra-uterine exposures to toxicants, history of closed head injury with loss of consciousness, history of a language disorder or Axis 1 psychiatric disorder, first degree relative with a lifetime history of an Axis 1 psychiatric disorder, abnormality on neurological examination). We also excluded subjects with disorders that would prevent completion of the assessments (e.g., pacemaker, metal implants), other forms of congenital heart disease requiring surgical correction, or primary language other than English.

In group 1, the intraoperative data points were obtained from a computerized query of the Microsoft SQL2003 database providing storage for data from Vanderbilt University's electronic anesthesiology documentation system, the Vanderbilt Perioperative Informatics Medical System (VPIMS)©. Data queried from the database included intraoperative pulse oximetry (SpO2) values (Nellcor pulse oximeters via a Philips Intellivue MP 90 monitor) and time correlated intraoperative partial pressure of oxygen (PaO2) determinations made by arterial blood sampling (Laboratory Gem Premier 3000, Instrumentation Technology) in all mechanically ventilated (MV) adults, undergoing general anesthesia. We excluded patients who were scheduled for cardiovascular surgeries, due to the potential effect of cardiopulmonary bypass and hypothermia on blood gas data, and those having thoracotomies with resultant lung resection or hypo-inflation for surgical purposes. In group 2, PaO2 and corresponding SpO2 values were obtained form the ARMA study database of patients with acute respiratory distress syndrome (ARDS).(8 (link))
In our discussions with experts in the field - both clinicians and researchers - the unmet need in this area was to develop an easy to use and reliable imputation for PF ratios by using SF threshold values, without having the clinicians and research personnel perform difficult calculations, incorporating the covariates that may have played a role in this relationship. Hence a decision was made first to develop a model without any covariates, enabling the calculation of the SOFA score when only SpO2 was available in a broad range of patients. To study the possible contribution of PEEP to the predictive value of SF and PF, we evaluated a second model to determine the relationship between SF and PF ratios within 3 categories of PEEP support: <8 centimeters of water (cm H2O), 8–12 cm H2O and > 12 cm H2O.

Continuous variables were presented as means with SD, while categorical variables were presented as frequencies. LOS at CICU and postoperative LOS were dichotomised to designate two groups (normal LOS and prolonged LOS). We defined prolonged LOS as ≥75th centile. In the absence of a prescribed LOS in the literature and to confirm the appropriateness of our selection, we consulted the surgeons for their judgement who agreed on this cut-off value. In general, there is a variability in medical research for defining the period at which a stay is considered as prolonged.14 (link) Moreover, the use of the LOS at the 75th centile is consistent with other studies. Postoperative LOS was defined as the time between the day of surgery and discharge from the hospital, while CICU LOS was defined as the time in days between the admission and discharge from CICU. For identifying difference between groups, we used t-tests for continuous variables, Mann-Whitney for non-normally distributed variables and χ2 for categorical variables.
For identifying predictors of postoperative LOS, a univariate logistic regression was first performed to select variables that are significantly related to the postoperative LOS. Factors with p<0.10 were then included in the multivariate analysis. These included sex, age, body mass index (BMI), history of diabetes, history of renal failure, history of cerebrovascular disease, history of respiratory disease, pulmonary hypertension, congestive heart failure (CHF) at current admission, preoperative arrhythmia, preoperative inotropic support, left ventricular ejection fraction (≥40% vs <40%), preoperative haematocrit (Hct) level, non-elective surgery, type of surgery, use of cardiopulmonary bypass (CPB) machine, inotropic support after operation, use of packed red blood cells (PRBC) and number of complications. A backward stepwise logistic regression was used to identify factors that had an independent effect on the postoperative LOS. A p value of 0.1 to enter a factor and 0.2 to remove it were used.

The cohort of children was prospectively enrolled from 3 pediatric sites: Cincinnati Children’s Hospital Medical Center, Montreal Children’s Hospital, and Yale New-Haven Children's Hospital as part of the consortium investigating new biomarkers in AKI known as the Translational Research Investigating Biomarker Endpoints in Acute Kidney Injury (TRIBE-AKI). Enrollment started in July 2007, November 2007, and November 2008, respectively, and completed in December 2009. Cincinnati has a dedicated pediatric cardiac care unit (CCU) with approximately 225 cardiopulmonary bypass cases annually and both Montreal and Yale have mixed medical surgical units including cardiac patients with approximately 60 cardiopulmonary bypass cases annually. This study was approved by the Institutional Review Board or Research Ethics Board of each institution. Written informed consent from legal guardians and assent from patients were obtained before enrollment.
All patients less than 18 years of age undergoing cardiac surgery with cardiopulmonary bypass were eligible for the study. Exclusion criteria included history of prior renal transplantation, dialysis requirement, or participation in a conflicting research study. We utilized the Risk Adjustment for Congenital Heart Surgery 1 (RACHS-1) consensus-based scoring system to categorize the complexity of surgery (24 (link)). This method of risk stratification is a widely accepted tool for the evaluation of differences in outcomes of surgery for congenital heart disease. We only retained children older than 1 month for this study, since defining AKI in neonates is unclear and likely different than the AKI definition in older children (25 (link)).

Example 3

Systemic Inflammatory Response Syndrome (SIRS) can occur in association with cardiopulmonary bypass (CPB) surgery, resulting in multiple organ dysfunction (MOD). Activated neutrophils have been implicated as major inciting factors in this process. This example describes in vitro and in vivo experiments that evaluate the effect of SCD cartridges for use during CPB surgery. The results demonstrate that the usage of SCD cartridges may disrupt the systemic leukocyte response during CPB surgery, leading to improved outcomes for CPB-mediated MOD.

PEA was performed from median sternotomy, the patient was cooled to 18°C to 20°C using cardiopulmonary bypass (CBP), and bilateral PEA was performed under deep hypothermic circulatory arrest. Unfractionated heparin (Leo Pharmaceutical Products, Denmark) was used for intraoperative anticoagulation monitored by activated clotting time (ACT) (target > 480 s Kaolin-ACT, Medtronic.Inc. ACTII, Minneapolis, MN, USA). Before the initiation of CBP, 500 to 1000 ml of blood was harvested, and returned to the patient after weaning off CPB, heparin reversal by protamine sulfate, and decannulation. During CPB to maintain patients’ volume status and to minimize the use of crystalloids (plasmalyte 50 mg/ml, Baxter) and possible volume overload autologous blood transfusion (cell saver), allogenic red blood cell (RBC) transfusions (Hb < 60 g/l), 2 to 6 units of solvent-detergent treated standardized plasma (Octaplas®, Octapharma AG, Lachen, Switzerland) or albumin 20% were used. Tranexamic acid was used 30 mg/kg intravenously before the surgical incision and again 15 mg/kg every 2 h for the duration of CPB. ACT was controlled every 20 min on CPB and 3 min after each heparin bolus. After CPB, administration of protamine and harvested blood infusion, coagulation status was controlled (heparinase-ACT, complete blood count, APTT, PT, fibrinogen, AT and D-dimer). Postoperatively in the operation room allogenic RBC were transfused if Hb < 90 g/l or Hct < 30%. The threshold for platelet transfusion was the platelet count <100 ×109/l and for standardized plasma, Octaplas®, PT < 30%.

Our study cohort included eight children aged 6–10 years who were hospitalised in the Affiliated Hospital of Southwest Medical University, China on June 2022. Four of the children were diagnosed by echocardiography as VSD without PAH (control group, n = 4) and the other four were diagnosed by echocardiography and right cardiac catheterisation as moderate or severe PAH secondary to VSD (PAH group, n = 4). A diagnosis of PAH by right-heart catheterisation was defined as a mean pulmonary arterial pressure >25 mmHg at rest, a pulmonary capillary wedge pressure <15 mmHg and a pulmonary vascular resistance of >3 Wood units. We excluded patients receiving targeted therapy for PAH and those diagnosed with other intracardiac malformations, such as patent ductus arteriosus, large atrial septal defect, or other related conditions, like congenital lung disease, bronchial asthma and congenital pulmonary vascular malformation.
During the cardiac operation, atrial appendage specimens were collected from all patients before cardiopulmonary bypass and blood samples were collected via the jugular vein before performing the midline sternotomy. The plasma and right atrial appendage specimens were then aliquoted and stored at −80°C until RNA extraction.
