Abstract
Background: Various inotropes and inodilators have been utilized to treat low cardiac output syndrome after the arterial switch operation. The use of levosimendan, a calcium sensitizer has been limited in this setting. This study compares the effects of levosimendan with milrinone in managing low cardiac output after the arterial switch operation. Methods: A retrospective, comparative study was conducted in a tertiary care hospital on patients weighing up to 3 kg undergoing the arterial switch operation between January 2017 and January 2022. Patients received a loading dose followed by continuous infusion of either levosimendan or milrinone. Echocardiographic, hemodynamic and biochemical parameters were compared. Results: Forty-three patients received levosimendan and 42 patients received milrinone as the primary test drug. Cardiac index of less than 2.2 L/min/m2 on postoperative day 1 and 2 was found in 9.3% and 2.3% of patients receiving levosimendan versus 26.2% and 11.9% in those receiving milrinone, respectively (P = .04 and .08, respectively). Early lactate-clearance and better central venous oxygen saturations were noted in the levosimendan group. Prevalence of acute kidney injury was higher in the milrinone group (50% vs 28%; P = .03). Use of peritoneal dialysis in the milrinone group versus levosimendan was 31% and 16.3%, respectively (P = .11). There was no difference in hospital mortality between the groups (milrinone, 3; levosimendan, 2, P = .62). Conclusions: Levosimendan is safe and as effective as milrinone to treat low cardiac output syndrome occurring in neonates after the arterial switch operation. In addition we found that levosimendan was renal protective when compared with milrinone.

Abstract
OBJECTIVE Oral feeding difficulty is common in infants after congenital heart disease (CHD) surgical repair and is associated with prolonged hospital stay and increased risk for tube-feeding at discharge (TF). The current understanding of the enteropathogenesis of oral feeding difficulty in infants requiring CHD surgery is limited. To determine the prevalence and risk factors for TF following CHD surgery in early infancy. STUDY DESIGN This was a 6-year single-center retrospective cohort study (2016-2021) of infants under 6 months who had CHD surgery. Infants required TF were compared with infants who reached independent oral feeding (IOF). RESULTS Of the final sample of 128 infants, 24 (18.8%) infants required TF at discharge. The risk factors for TF in univariate analysis include low birth weight, low 5-minute Apgar score, admitted at birth, risk adjustment in congenital heart surgery categories IV to VI, presence of genetic diagnosis, use of Prostin, higher pre- and postsurgery respiratory support, lower weight at surgery, lower presurgery oral feeding, higher presurgery milk calory, delayed postsurgery enteral and oral feeding, higher pre- and postsurgery gastroesophageal reflux disease (GERD), need for swallow study, abnormal brain magnetic resonance imaging (p < 0.05). In the multivariate analysis, only admitted at birth, higher presurgery milk calories, and GERD were significant risk factors for TF. TF had significantly longer hospital stay (72 vs. 17 days) and lower weight gain at discharge (z-score: -3.59 vs. -1.94) compared with IOF (p < 0.05). CONCLUSION The prevalence of TF at discharge in our study is comparable to previous studies. Infants with CHD admitted at birth, received higher presurgery milk calories, and clinical GERD are significant risk factors for TF. Mitigating the effects of identified risk factors for TF will have significant impact on the quality of life for these infants and their families and may reduce health care cost. KEY POINTS · Oral feeding difficulty in infants after congenital heart disease surgical repair is common.. · Such infants require prolonged hospital stay and higher risk for tube-feeding at discharge.. · Identifying modifiable risk factors associated with tube-feeding can enhance clinical outcomes..

Abstract
OBJECTIVES Cardiac surgery on cardiopulmonary bypass (CPB) during the neonatal period can cause perioperative organ injuries. The primary aim of this study was to determine the incidence and risk factors associated with postoperative mechanical ventilation duration and acute lung injury after the arterial switch operation (ASO). The secondary aim was to examine the utility of the Brixia score for characterizing postoperative acute lung injury (ALI). DESIGN A retrospective study. SETTING A single-center university hospital. PARTICIPANTS A total of 93 neonates with transposition of great arteries with intact ventricular septum (dTGA IVS) underwent ASO. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS From January 2015 to December 2022, 93 neonates with dTGA IVS were included in the study. The cohort had a median age of 4.0 (3.0-5.0) days and a mean weight of 3.3 ± 0.5 kg. About 63% of patients had ≥48 hours of postoperative mechanical ventilation after ASO. Risk factors included prematurity, post-CPB transfusion of salvaged red cells, platelets and cryoprecipitate, and postoperative fluid balance by univariate analysis. The larger transfused platelet volume was associated with the risk of ALI by multivariate analysis. The median baseline Brixia scores were 11.0 (9.0-12.0) and increased significantly in the postoperative day 1 in patients who developed moderate ALI 24 hours after admission to the intensive care unit (15.0 [13.0-16.0] v 12.0 [10.0-14.0], p = 0.046). CONCLUSIONS Arterial switch operation results in a high incidence of ≥48-hour postoperative mechanical ventilation. Blood component transfusion is a potentially modifiable risk factor. The Brixia scores also may be used to characterize postoperative acute lung injury.

Abstract
BACKGROUND Prolonged intensive care unit (ICU) stays consume medical resources and increase medical costs. This study identified risk factors associated with prolonged postoperative intensive care unit (ICU) stay in children with total anomalous pulmonary venous connection (TAPVC). METHODS The medical records of 85 patients who underwent surgical repair of TAPVC were retrospectively analyzed. The patients were divided into prolonged-stay and standard-stay groups. The prolonged stay group included all patients who exceeded the 75th percentile of the ICU stay duration, and the standard stay group included all remaining patients. The effects of patient variables on ICU stay duration were investigated using univariate and logistic regression analyses. RESULTS Patient median age was 41 (18-103) days, and median weight was 3.80 (3.30-5.35) kg.Postoperative duration of ICU stay was 11-68 days in the prolonged stay group (n = 23) and 2-10 days in the standard stay group (n = 62). Lower preoperative pulse oximetry saturation (SpO2), higher intraoperative plasma lactate levels, and prolonged postoperative mechanical ventilation were independent risk factors for prolonged ICU stay. Preoperative SpO2 < 88.5%, highest plasma lactate value > 4.15 mmol/L, and postoperative mechanical ventilation duration was longer than 53.5 h, were associated with increased risk of prolonged ICU stay. Young age, low body weight, subcardiac type, need for vasoactive drug support, emergency surgery, long anesthesia time, low SpO2 after anesthesia induction, long cardiopulmonary bypass (CPB) and aortic clamp times, high lactate level, low temperature, large volume of ultrafiltration during CPB, large amounts of chest drainage, large red blood cells (RBCs) and plasma transfusion, and postoperative cardiac dysfunction may be associated with prolonged ICU stay. CONCLUSIONS Lower preoperative SpO2, higher intraoperative plasma lactate levels, and prolonged postoperative mechanical ventilation were independent risk factors for prolonged ICU stay in children with TAPVC. When SpO2 was lower than 88.5%, the highest plasma lactate value was more than 4.15 mmol/L, and the postoperative mechanical ventilator duration was longer than 53.5 h, the risk of prolonged ICU stay increased. Improved clinical management, including early diagnosis and timely surgical intervention to reduce hypoxia time and protect intraoperative cardiac function, may reduce ICU stay time.

Abstract
Background Reports of long-term mortality and reintervention after transposition of the great arteries with intact ventricular septum treatment, although favorable, are mostly limited to single-center studies. Even less is known about hospital resource utilization (days at hospital) and the impact of treatment choices and timing on outcomes. Objectives The purpose of this study was to describe survival, reintervention and hospital resource utilization after arterial switch operation (ASO) in a national dataset. Methods Follow-up and life status data for all patients undergoing ASO between 2000 and 2017 in England and Wales were collected and explored using multivariable regressions and matching. Results A total of 1,772 patients were identified, with median ASO age of 9.5 days (IQR: 6.5-14.5 days). Mortality and cardiac reintervention at 10 years after ASO were 3.2% (95% CI: 2.5%-4.2%) and 10.7% (95% CI: 9.1%-12.2%), respectively. The median time spent in hospital during the ASO spell was 19 days (IQR: 14, 24). Over the first year after the ASO patients spent 7 days (IQR: 4-10 days) in hospital in total, decreasing to 1 outpatient day/year beyond the fifth year. In a subgroup with complete risk factor data (n = 652), ASO age, and balloon atrial septostomy (BAS) use were not associated with late mortality and reintervention, but cardiac or congenital comorbidities, low weight, and circulatory/renal support at ASO were. After matching for patient characteristics, BAS followed by ASO and ASO as first procedure, performed within the first 3 weeks of life, had comparable early and late outcomes, including hospital resource utilization. Conclusions Mortality and hospital resource utilization are low, while reintervention remains relatively frequent. Early ASO and individualized use of BAS allows for flexibility in treatment choices and a focus on at-risk patients.

Abstract
Background and aims Cardiac surgery and cardiopulmonary bypass result in an immunoparalyzed state in children making them susceptible to sepsis and other hospital-acquired infections. Therefore, identification of the risk factors of sepsis would lead to appropriate management. The current study seeks to evaluate the prevalence of sepsis and risk factors linked to sepsis in pediatric cardiac surgical patients and the subsequent prevalence of multidrug-resistant organisms. Methods A retrospective, single-center observational study was conducted including 100 pediatric patients admitted to the pediatric intensive care unit (ICU) after cardiac surgery between January 2017 and February 2018. All patient data were obtained from the medical record department of the hospital. Patient case report form comprised demography, surgery details, preoperative and postoperative hematological reports, and clinical details. After collecting the data, chi-square test and logistic regression analysis were used to determine the risk factors linked to sepsis. Results The prevalence of sepsis in our population was 27% and the mortality rate due to sepsis was 1%. The only statistically significant risk factor for sepsis we discovered in this analysis was prolonged ICU stay for more than 5 days. A total of eight patients had blood cultures positive for bacterial infection. The alarming finding was that all eight were infected with multidrug-resistant organisms, demanding the last line of antibacterials. Conclusion Our study indicates that special clinical care is required when ICU stay is prolonged to lower the risk of sepsis. These new and upcoming infections not only promote high mortality and morbidity rates but also contribute to increased cost of care due to the use of newer broad-spectrum antibiotics and longer hospital stay. The high prevalence of multidrug-resistant organisms is unacceptable in the current scenario and hospital infection and prevention control play a crucial role in minimizing such infections.

Abstract
OBJECTIVES Greater congenital heart disease (CHD) complexity is associated with lower health-related quality of life (HRQOL). There are no data on the association between surgical and ICU factors and HRQOL in CHD survivors. This study assess the association between surgical and ICU factors and HRQOL in child and adolescent CHD survivors. DESIGN This was a corollary study of the Pediatric Cardiac Quality of Life Inventory (PCQLI) Testing Study. SETTING Eight pediatric hospitals participating in the PCQLI Study. PATIENTS Patients in the study had the Fontan procedure, surgery for tetralogy of Fallot (TOF), and transposition of the great arteries (TGAs). MEASUREMENTS AND MAIN RESULTS Surgical/ICU explanatory variables were collected by reviewing the medical records. Primary outcome variables (PCQLI Total patient and parent scores) and covariates were obtained from the Data Registry. General linear modeling was used to create the multivariable models. There were 572 patients included: mean ± sd of age 11.7 ± 2.9 years; CHD Fontan 45%, TOF/TGA 55%; number of cardiac surgeries 2 (1-9); and number of ICU admissions 3 (1-9). In multivariable models, lowest body temperature on cardiopulmonary bypass (CPB) was negatively associated with patient total score (p < 0.05). The total number of CPB runs was negatively associated with parent-reported PCQLI Total score (p < 0.02). Cumulative days on an inotropic/vasoactive drug in the ICU was negatively associated with all patient-/parent-reported PCQLI scores (p < 0.04). Neurological deficit at discharge was negatively associated with parent-reported PCQLI total score (p < 0.02). The variance explained by these factors ranged from 24% to 29%. CONCLUSIONS Surgical/ICU factors, demographic, and medical care utilization variables explain a low-to-moderate amount of variation in HRQOL. Research is needed to determine whether modification of these surgical and ICU factors improves HRQOL, and to identify other factors that contribute to unexplained variability.

Abstract
Sepsis remains among the most common causes of mortality in children with congenital heart disease (CHD). Extensive literature is available regarding managing sepsis in pediatric patients without CHD. Because the cardiovascular pathophysiology of children with CHD differs entirely from their typical peers, the available diagnosis and management recommendations for sepsis cannot be implemented directly in children with CHD. This review discusses the risk factors, etiopathogenesis, available diagnostic tools, resuscitation protocols, and anesthetic management of pediatric patients suffering from various congenital cardiac lesions. Further research should focus on establishing a standard guideline for managing children with CHD with sepsis and septic shock admitted to the intensive care unit.

Abstract
Neurodevelopmental impairment is a common and important long-term morbidity among infants with congenital heart disease (CHD). More than half of those with complex CHD will demonstrate some form of neurodevelopmental, neurocognitive, and/or psychosocial dysfunction requiring specialized care and impacting long-term quality of life. Preventing brain injury and treating long-term neurologic sequelae in this high-risk clinical population is imperative for improving neurodevelopmental and psychosocial outcomes. Thus, cardiac neurodevelopmental care is now at the forefront of clinical and research efforts. Initial research primarily focused on neurocritical care and operative strategies to mitigate brain injury. As the field has evolved, investigations have shifted to understanding the prenatal, genetic, and environmental contributions to impaired neurodevelopment. This article summarizes the recent literature detailing the brain abnormalities affecting neurodevelopment in children with CHD, the impact of genetics on neurodevelopmental outcomes, and the best practices for neonatal neurocritical care, focusing on developmental care and parental support as new areas of importance. A framework is also provided for the infrastructure and resources needed to support CHD families across the continuum of care settings.

Is arterial switch operation possible with neonatology-focused intensive care unit modality. TURK GOGUS KALP DAMAR CERRAHISI DERGISI-TURKISH JOURNAL OF THORACIC AND CARDIOVASCULAR SURGERY 2021; 29:136-142. [PMID: 34104506 PMCID: PMC8167476 DOI: 10.5606/tgkdc.dergisi.2021.20309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 01/06/2021] [Indexed: 11/29/2022]
Abstract
Background
In this study, we aimed to examine the feasibility of arterial switch operation and its perioperative management with neonatology-focused intensive care modality in a region of Turkey where the birth rate and the number of asylum seekers who had to leave their country due to regional conflicts are high.
Methods
Between December 2017 and June 2020, a total of 57 patients (48 males, 9 females; median age: 12.2 days; range, 2 to 50 days) who were diagnosed with transposition of the great arteries in our clinic and underwent arterial switch operation were retrospectively analyzed. All patients were followed by the neonatologist in the neonatal intensive care unit during the preoperative and postoperative period.
Results
Thirty-eight (66.7%) patients had intact ventricular septum, 16 (28.1%) had ventricular septal defect, two (3.5%) had coarctation of the aorta, and one (1.7%) had Taussig-Bing anomaly. Coronary artery anomaly was present in 14 (24.5%) patients. The most common complications in the intensive care unit were renal failure requiring peritoneal dialysis in seven (12.3%) patients, supraventricular tachyarrhythmia in six (10.5%) patients, and eight (14%) patients left their chests open. The median length of stay in intensive care unit was 13.8 (range, 9 to 25) days and the median length of hospital stay was 24.5 (range, 16 to 47) days. The overall mortality rate for all patients was 12.3% (n=7). The median follow-up was 8.2 months. A pulmonary valve peak Doppler gradient of ≥36 mmHg was detected in five patients (8.7%) who were followed, and these patients were monitored by providing medical treatment. None of the patients needed reoperation or reintervention.
Conclusion
We believe that arterial switch operation, one of the complex neonatal cardiac surgery, can be performed with an acceptable mortality and morbidity rate with the use of neonatology-focused intensive care modality, which is supported by pediatric cardiology and pediatric cardiac surgery.

Pediatr Cardiol 2021; 42:597-605.

Abstract
Once a mainstay in the treatment of neonates with d-transposition of the great arteries (d-TGA), the application of balloon atrial septostomy (BAS) in the d-TGA population has become more selective. Currently, there is no clear evidence for or against a selective BAS strategy. The aims of this single-center retrospective study were to determine the incidence of BAS in the neonatal d-TGA population in the current era, to measure the rate of procedural success, and to compare the outcomes and complication rates of patients who underwent BAS to those who underwent neonatal ASO alone. Between 2012 and 2018, 147 patients with d-TGA underwent initial medical management and ASO, 73 of which underwent BAS. The percentage of patients that underwent BAS decreased from 73 to 33% over the study time period. In patients with d-TGA with intact ventricular septum, 33% of patients remained off of PGE1 at the time of surgery regardless of BAS. In d-TGA with ventricular septal defect, 85.7% of those that underwent BAS and 54.1% of those who did not remained off of PGE1 at the time of surgery, however, this difference did not reach statistical significance. In this single institution retrospective cohort of patients with d-TGA, the performance of a technically successful balloon atrial septostomy did not eliminate the need for PGE1 therapy at the time of definitive ASO. This was true regardless of the presence or absence of a ventricular septal defect.

Abstract
OBJECTIVE To determine whether the presence of a standardized feeding protocol improves outcomes in a subset of neonates undergoing cardiac surgery. DESIGN Retrospective cohort study. SETTING Cardiovascular ICU at a freestanding academic children's hospital. PATIENTS Neonates with a diagnosis of d-transposition of the great arteries undergoing arterial switch operation from January 2007 to June 2017. INTERVENTIONS Initiation of perioperative feeding protocols. MEASUREMENTS AND MAIN RESULTS Patients were evaluated before and after implementation of standardized perioperative feeding protocols in neonates with d-transposition of the great arteries undergoing arterial switch operation. Low-risk patients born after initiation of nurse-driven protocols were compared with a similar historical group. Data obtained included time to achievement of feeding goals, with primary outcome being weight gain at hospital discharge. Other measures analyzed included duration of mechanical ventilation and postoperative hospital length of stay. Overall, 33 patients in the protocol group were compared with 44 patients in the historical group. No significant baseline differences existed between the two cohorts. The protocol group achieved improved feeding outcomes in nearly all measured categories, including introduction to enteral feeds preoperatively (91% vs 59%; p < 0.01) and earlier attainment of postoperative full enteral feeds of 120 mL/kg/d (2 vs 5 d; p < 0.01). Protocol patients had significantly improved weight gain at the time of discharge (60 vs 1 g; p < 0.01), while achieving shorter postoperative length of stay (10.1 vs 12.6 d; p = 0.04). CONCLUSIONS An aggressive, but safe, perioperative feeding protocol implemented in a homogenous low-risk neonatal cardiac surgical population improves feeding outcomes, including increased weight gain, as well as decreased postoperative length of stay. Consideration for perioperative feeding protocol implementation and further study should be given.

Abstract
INTRODUCTION Post-operative length of stay (LOS) after the arterial switch operation (ASO) is variable. The association between pre-operative non-invasive measures of ventricular function and post-operative course has not been well established. The aims of this study were to (1) evaluate the relationship between pre-operative non-invasive measures of ventricular function and post-operative LOS and (2) evaluate the change in ventricular function after ASO. METHODS Data were reviewed in consecutive ASO patients between 2010 and 2016. The primary outcome was post-operative LOS. Echocardiograms obtained during the pre-operative period and at the time of discharge were retrospectively analyzed using speckle-tracking echocardiography. Pearson's correlation between patient-specific, pre-operative, and echocardiographic data versus post-operative LOS was assessed. RESULTS Fifty-two patients were included in analyses, 39 neonates and 13 infants. Left ventricular (LV) longitudinal strain correlated with post-operative LOS for infants age > 28 days (r = 0.62, p = 0.03), but not for neonates (r = 0.14, p = 0.40). Operative age (r = - 0.42, p = 0.003), weight at surgery (r = - 0.48, p ≤ 0.001), and cardiopulmonary bypass time (r = 0.30, p = 0.045) also correlated with post-operative LOS. Standard 2D measures of ventricular function did not correlate with post-operative LOS. LV ejection fraction and longitudinal strain worsened post-operatively. CONCLUSION Higher pre-operative LV longitudinal strain (representing worse LV function) is associated with increased post-operative LOS after ASO in infants > 28 days, but not in neonates. LV ejection fraction and longitudinal strain worsened after ASO. Future studies should assess the utility of performing STE in risk stratifying patients prior to ASO.

Abstract
Acute kidney injury (AKI) is a common complication of pediatric cardiac surgery and is associated with increased morbidity and mortality. Literature of AKI after pediatric cardiac surgery is comprehensively reviewed in terms of incidence, risk factors, biomarkers, treatment and prognosis. The novel RIFLE (pediatric RIFLE for pediatrics), Acute Kidney Injury Network (AKIN) and Kidney Disease Improving Global Outcomes (KDIGO) criteria have brought about unified diagnostic standards and comparable results for AKI after cardiac surgery. Numerous risk factors, either renal or extrarenal, can be responsible for the development of AKI after cardiac surgery, with low cardiac output syndrome being the most pronounced predictor. Early fluid overload is also crucial for the occurrence of AKI and prognosis in pediatric patients. Three sensitive biomarkers, neutrophil gelatinase-associated lipocalin, cystatin C (CysC) and liver fatty acid-binding protein, are regarded as the earliest (increase at 2-4 h), and another two, kidney injury molecule-1 and interleukin-18 represent the intermediate respondents (increase at 6-12 h after surgery). To ameliorate the cardiopulmonary bypass techniques, improve renal perfusion and eradicate the causative risk factors are imperative for the prevention of AKI in pediatric patients. The early and intermediate biomarkers are helpful for an early judgment of occurrence of postoperative AKI. Improved survival has been achieved by prevention, renal support and modifications of hemofiltration techniques. Further development is anticipated in small children.

Abstract
Many infants with complex congenital heart disease (CHD) do not develop the skills to feed orally and are discharged home on gastrostomy tube or nasogastric feeds. We aimed to identify risk factors for failure to achieve full oral feeding and evaluate the efficacy of oral motor intervention for increasing the rate of discharge on full oral feeds by performing a prospective study in the neonatal and cardiac intensive care units of a tertiary children's hospital. 23 neonates born at ≥37weeks gestation and diagnosed with single-ventricle physiology requiring a surgical shunt were prospectively enrolled and received oral motor intervention therapy. 40 historical controls were identified. Mean length of stay was 53.7days for the control group and 40.9days for the study group (p=0.668). 13/23 patients who received oral motor intervention therapy (56.5%) and 18/40 (45.0%) controls were on full oral feeds at discharge, a difference of 11.5% (95% CI -13.9% to 37.0%, p=0.378). Diagnosis of hypoplastic left heart syndrome, longer intubation and duration of withholding enteral feeds, and presence of gastroesophageal reflux disease were predictors of poor oral feeding on univariate analysis. Although we did not detect a statistically significant impact of oral motor intervention, we found clinically meaningful differences in hospital length of stay and feeding tube requirement. Further research should be undertaken to evaluate methods for improving oral feeding in these at-risk infants.

Abstract
AIM Vascular leakage following cardiopulmonary bypass contributes to morbidity. Angiopoietin-1 and -2 are biomarkers of endothelial dysfunction. Our aim was to characterize Ang-1 and -2 association with clinical characteristics and outcomes. METHODS Observational cohort study measuring Ang-1/-2 with a panel of cytokines in adults undergoing cardiopulmonary bypass. RESULTS Ang-2 levels increased immediately postop whereas Ang-1 levels decreased over time. No significant correlation was found with other inflammatory mediators. High correlation was found between the hospital length of stay and Ang-2 increase at 24 h (rho = 0.590; p < 0.0001). The predictors of Ang-2 increase were female gender, cross clamp time, transfusion of blood and absence of angiotensin-converting enzyme inhibitor as a pre-op medication. CONCLUSION Angiopoietins can detect vascular leakage early and could impact patient's management to decrease length of stay after cardiac surgery.

Abstract
As preoperative morbi-mortality remains significant, care of newborns with transposition of the great arteries is still challenging. In this review of the literature, we discuss the different treatments that could improve the patient's condition into the preoperative period. Instead of a standardized management, we advocate personalized care of these neonates. Considering the deleterious effects of hypoxia, special attention is given to the use of non-invasive technologies to assess oxygenation of the tissues. As a prolonged preoperative time with low cerebral oxygenation is associated with cerebral injuries, distinguishing neonates who should undergo early surgery from those who could wait longer is crucial and requires full expertise in the management of neonatal congenital heart disease. Finally, to treat these newborns as soon as possible, we support a planned delivery policy for foetuses with transposition of the great arteries.

Abstract
OBJECTIVES In this review, we will discuss risk factors for developing sepsis; the role of biomarkers in establishing an early diagnosis, in monitoring therapeutic efficacy, in stratification, and for the identification of sepsis endotypes; and the pathophysiology and management of severe sepsis and septic shock, with an emphasis on the impact of sepsis on cardiovascular function. DATA SOURCE MEDLINE and PubMed. CONCLUSIONS There is a lot of excitement in the field of sepsis research today. Scientific advances in the diagnosis and clinical staging of sepsis, as well as a personalized approach to the treatment of sepsis, offer tremendous promise for the future. However, at the same time, it is also evident that sepsis mortality has not improved enough, even with progress in our understanding of the molecular pathophysiology of sepsis.

Abstract
Mortality for the arterial switch operation (ASO) has diminished significantly over the past few decades. Some patients do, however, continue to have protracted and complicated courses after surgery. We attempted to determine which preoperative factors were best associated with prolonged hospital stay after ASO. We retrospectively reviewed all patients that underwent an ASO over a 10-year period. Outcomes of patients with postoperative stays (POS) >14 days (long stay group-LS) were compared with those patients with POS < 7 days (short stay group-SS). The following variables were evaluated: age at surgery, weight, septostomy performed (BAS) and management the day prior to surgery including use of prostaglandin E1 (PGE1), inotropes, intubation status and the establishment of enteral feeds. The SS group had 25 patients and the LS group had 32 patients. Both groups (SS vs. LS) were similar in PGE1 use (48 vs. 69 %), BAS (76 vs. 59 %), age at surgery (6 vs. 7 days) and preoperative inotropes (12 vs. 38 %). The SS group had significantly higher incidence of preoperative feeding (80 vs. 31 %, p < 0.001) and less frequent intubation (12 vs. 47 %, p < 0.001). Patients who are intubated and have not yet begun to receive enteral feeds at the time of their ASO are more likely to have prolonged POS. It is unclear if prolonged stays were a result of operating on patients with worse preoperative hemodynamics or a consequence of a preoperative management strategy that did not allow for extubation and establishment of feeds prior to surgery.

Abstract
The premature neonate with congenital heart disease (CHD) represents a challenging population for clinicians and researchers. The interaction between prematurity and CHD is poorly understood; epidemiologic study suggests that premature newborns are more likely to have CHD and that fetuses with CHD are more likely to be born premature. Understanding the key physiologic features of this special patient population is paramount. Clinicians have debated optimal timing for referral for cardiac surgery, and management in the postoperative period has rapidly advanced. This article summarizes the key concepts and literature in the care of the premature neonate with CHD.

Abstract
Increased extravascular lung water (EVLW) may contribute to respiratory failure in neonates. Accurate measurement of EVLW in these patients is limited due to the lack of bedside methods. The aim of this pilot study was to investigate the reliability of the transpulmonary ultrasound dilution (TPUD) technique as a possible method for estimating EVLW in a neonatal animal model. Pulmonary edema was induced in 11 lambs by repeated surfactant lavages. In between the lavages, EVLW indexed by bodyweight was estimated by TPUD (EVLWItpud) and transpulmonary dye dilution (EVLWItpdd) (n = 22). Final EVLWItpud measurements were also compared with EVLWI estimations by gold standard post mortem gravimetry (EVLWIgrav) (n = 6). EVLWI was also measured in two additional lambs without pulmonary edema. Bland–Altman plots showed a mean bias between EVLWItpud and EVLWItpdd of −3.4 mL/kg (LOA ± 25.8 mL/kg) and between EVLWItpud and EVLWIgrav of 1.7 mL/kg (LOA ± 8.3 mL/kg). The percentage errors were 109 and 43 % respectively. The correlation between changes in EVLW measured by TPUD and TPDD was r2 = 0.22. Agreement between EVLWI measurements by TPUD and TPDD was low. Trending ability to detect changes between these two methods in EVLWI was questionable. The accuracy of EVLWItpud was good compared to the gold standard gravimetric method but the TPUD lacked precision in its current prototype. Based on these limited data, we believe that TPUD has potential for future use to estimate EVLW after adaptation of the algorithm. Larger studies are needed to support our findings.

Abstract
This paper proposes a new statistical approach for predicting postoperative morbidity such as intensive care unit length of stay and number of complications after cardiac surgery in children. In a recent multi-center study sponsored by the National Institutes of Health, 311 children undergoing cardiac surgery were enrolled. Morbidity data are count data in which the observations take only nonnegative integer values. Often, the number of zeros in the sample cannot be accommodated properly by a simple model, thus requiring a more complex model such as the zero-inflated Poisson regression model. We are interested in identifying important risk factors for postoperative morbidity among many candidate predictors. There is only limited methodological work on variable selection for the zero-inflated regression models. In this paper, we consider regularized zero-inflated Poisson models through penalized likelihood function and develop a new expectation-maximization algorithm for numerical optimization. Simulation studies show that the proposed method has better performance than some competing methods. Using the proposed methods, we analyzed the postoperative morbidity, which improved the model fitting and identified important clinical and biomarker risk factors.

Abstract
BACKGROUND AND OBJECTIVES Evaluate risk factors for and impact of acute kidney injury on children following the arterial switch operation. DESIGN Single-center retrospective chart review. SETTING A tertiary children's hospital. PATIENTS A total of 92 patients receiving the arterial switch operation from 1997 to 2008 at severe acute kidney injury was defined as a 100% serum creatinine rise over baseline. RESULTS Of 92 patients, 18 (20%) developed severe acute kidney injury. Neither patient age or weight nor cardiopulmonary bypass time correlated with the development of acute kidney injury. Acute kidney injury was associated with the following: higher postoperative day 1 (POD1) fluid balance, higher inotrope scores (POD1 and POD2), and longer: postoperative ICU length of stay (p = 0.005), overall ICU length of stay (p = 0.05), and postoperative hospital length of stay (p = 0.006). The time to peak creatinine for acute kidney injury patients was between POD1 and POD2. Correction of serum creatinine for fluid balance increased the population defined as severe acute kidney injury and strengthened the association of acute kidney injury with postoperative morbidity. CONCLUSIONS Acute kidney injury following the arterial switch operation is associated with increased morbidity. In this single center, single population, and homogenous cohort of patients, the development of acute kidney injury was not correlated with age, size, or cardiopulmonary bypass time, but was still associated with prolonged duration of ventilation and hospitalization. Notably, the failure to correct serum creatinine for fluid balance underestimates the prevalence and impact of acute kidney injury.

Pediatr Cardiol 2012; 33:1383-90.

Abstract
This study aimed specifically to identify the predictors of prolonged recovery after the arterial switch operation for transposition of the great arteries in infants. The clinical records of all infants admitted to the surgical intensive care unit (SICU) between January 2000 and March 2011 after an arterial switch operation were retrospectively reviewed. The cohort was divided into a prolonged recovery group that included all patients who exceeded the 75th percentile for duration of SICU stay and a standard recovery group that included all the remaining patients. Of the 102 patients in the final analysis, 31 experienced prolonged recovery. The median SICU stay was 18 days (range, 14-58 days) for the patients in the prolonged recovery group and only 8 days (range, 5-13 days) for the patients in the standard recovery group. After univariate analysis, a stepwise logistic regression model analysis was used to compare the demographic data as well as the pre-, intra-, and postoperative variables between the two groups. Of all the variables analyzed, high postbypass serum lactate level [odds ratio (OR), 2.610; 95 % confidence interval (CI), 1.464-4.653; p = 0.039], need for larger volume of resuscitation fluid (OR, 3.154; 95 % CI, 1.751-5.682; p = 0.018), and noninfectious pulmonary complication (OR, 2.844; 95 % CI, 1.508-5.363; p = 0.025) were identified as independent risk factors for prolonged recovery among infants undergoing an arterial switch operation for transposition of the great arteries.

Morbidity of the arterial switch operation. Ann Thorac Surg 2012; 93:1977-83. [PMID: 22365263 DOI: 10.1016/j.athoracsur.2011.11.061] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2011] [Revised: 11/23/2011] [Accepted: 11/29/2011] [Indexed: 11/24/2022]
Abstract
BACKGROUND The arterial switch operation (ASO) has become a safe, reproducible surgical procedure with low mortality in experienced centers. We examined morbidity, which remains significant, particularly for complex ASO. METHODS From 2003 to 2011, 101 consecutive patients underwent ASO, arbitrarily classified as "simple" (n=52) or "complex" (n=49). Morbidity was measured in selected complications and postoperative hospitalization. Three outcomes were analyzed: ventilation time, postextubation hospital length of stay, and a composite morbidity index, defined as ventilation time+postextubation hospital length of stay+occurrence of selected major complications. Complexity was measured with the comprehensive Aristotle score. RESULTS The operative mortality was zero. Twenty-five major complications occurred in 23 patients: 6 of 25 (12%) in simple ASO and 19 of 49 (39%) in complex ASO (p=0.002). The most frequent complication was unplanned reoperation (15 vs 6, p=0.03). No patients required permanent pacing. The complex group had a significantly higher morbidity index and longer ventilation time and postextubation hospital length of stay. In multivariate analysis, factors independently predicting higher morbidity were the comprehensive Aristotle score, arch repair, bypass time, and malaligned commissures. Myocardial infarction caused one sudden late death at 3 months. Late coronary failure was 2%. Overall survival was 99% at a mean follow-up of 49±27 months. CONCLUSIONS In this consecutive series without operative mortality, morbidity was significantly higher in complex ASO. The only anatomic incremental risk factors for morbidity were aortic arch repair and malaligned commissures, but not primary diagnosis, weight less than 2.5 kg, or coronary patterns.

Abstract
The survival rate for children with congenital heart disease (CHD) has increased significantly coincident with improved techniques in cardiothoracic surgery, cardiopulmonary bypass and myocardial protection, and perioperative care. Cardiopulmonary bypass, likely in combination with ischemia-reperfusion injury, hypothermia, and surgical trauma, elicits a complex, systemic inflammatory response that is characterized by activation of the complement cascade, release of endotoxin, activation of leukocytes and the vascular endothelium, and release of proinflammatory cytokines. This complex inflammatory state causes a transient immunosuppressed state, which may increase the risk of hospital-acquired infection in these children. Postoperative sepsis occurs in nearly 3% of children undergoing cardiac surgery and has been associated with longer length of stay and mortality risks in the pediatric cardiac intensive care unit. Herein, we review the epidemiology, pathobiology, and management of sepsis in the pediatric cardiac intensive care unit.

Plasma angiopoietin-2 levels increase in children following cardiopulmonary bypass. Intensive Care Med 2008; 34:1851-7. [PMID: 18516587 DOI: 10.1007/s00134-008-1174-9] [Citation(s) in RCA: 32] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2008] [Accepted: 05/13/2008] [Indexed: 01/01/2023]
Abstract
OBJECTIVE The aim was to investigate the effects of cardiopulmonary bypass (CPB) on plasma levels of the vascular growth factors, angiopoietin (angpt)-1, angpt-2, and vascular endothelial growth factor (VEGF). DESIGN The design was a prospective, clinical investigation. SETTING The setting was a 12-bed pediatric cardiac intensive care unit of a tertiary children's medical center. PATIENTS The patients were 48 children (median age, 5 months) undergoing surgical correction or palliation of congenital heart disease who were prospectively enrolled following informed consent. INTERVENTIONS There were no interventions in this study. MEASUREMENTS AND RESULTS Plasma samples were obtained at baseline and at 0, 6, and 24 h following CPB. Angpt-1, angpt-2, and VEGF levels were measured via commercial ELISA. Angpt-2 levels increased by 6 h (0.95, IQR 0.43-2.08 ng mL(-1) vs. 4.62, IQR 1.16-6.93 ng mL(-1), P < 0.05) and remained significantly elevated at 24 h after CPB (1.85, IQR 0.70-2.76 ng mL(-1); P < 0.05). Angpt-1 levels remained unchanged immediately after CPB, but were significantly decreased at 24 h after CPB (0.64, IQR 0.40-1.62 ng mL(-1) vs. 1.99, IQR 1.23-2.63 ng mL(-1), P < 0.05). Angpt-2 levels correlated significantly with cardiac intensive care unit (CICU) length of stay (LOS) and were an independent predictor for CICU LOS on subsequent multivariate analysis. CONCLUSIONS Angpt-2 appears to be an important biomarker of adverse outcome following CPB in children.
