RESUMO
OBJECTIVES: To determine whether gross motor scores of toddlers after complex cardiac surgery were different from fine motor scores and were adequately represented by motor composite scores and, whether acute care predictors and chronic childhood health markers of gross motor scores differed from those of fine motor. METHODS: This prospective inception-cohort outcomes study included 171 toddlers after complex cardiac surgery with cardiopulmonary bypass at age <6 months, born in Northern Alberta from 2009 to 2019, and without known chromosomal abnormalities. At a mean (standard deviation) age of 21.7 (3.7) months, the Bayley Scales of Infant and Toddler Development-III determined motor composite and scaled scores (normative values, 100 (15), 10 (3), respectively). The same variables from surgery and assessment were analysed using multivariate regression to predict gross and fine motor scores; results expressed as effect size (95% confidence interval) with % variance. RESULTS: Composite, fine, and gross motor scores were 89.7 (14.2), 9.4 (2.5), and 7.2 (2.7), respectively. Predictive variables accounted for 21.2% of the variance for fine motor, and 36.9% for gross motor. Multivariate analysis for gross motor scores included toddlers need for cardiac medication, effect size (95% confidence interval) -0.801 (-1.62, -0.02), gastrostomy, -1.35 (-2.39, -0.319), and single ventricle, -0.93 (-1.71, -0.15). These same variables did not predict fine motor scores. CONCLUSION: Gross motor skills commonly were lower than fine motor skills for toddlers after complex cardiac surgery. Predictors for gross motor scores differed from fine motor scores. Separate reporting of gross motor scores could lead to improved identification of predictors of delay and to optimised early intervention.
RESUMO
To address the research hypothesis that the Alberta Infant Motor Scale (AIMS) completed following complex cardiac surgery (CCS) is a useful outcomes measure this study determined: (1) AIMS scores at age 8 months after CCS; (2) predictive validity of AIMS at 8 months for Bayley Scales of Infant and Toddler Development-III Gross Motor-scaled scores (GMSS) and diagnosis of cerebral palsy (CP) at 21 months; and (3) predictive demographic and surgical variables of AIMS scores. A prospective cohort study of 250/271 (92.3%) surviving children from Northern Alberta (born 2009-2020) who had CCS at age < 6 months determined AIMS scores at age mean (SD) 8.6 (2.4) and the GMSS at 21.9 (3.8) months. Gross motor delay was defined as AIMS < 5th percentile and GMSS as < 4 (-2SD). Predictions using multiple logistic regressions were expressed as Odds Ratios (OR) and 95% Confidence Interval (CI). Of children, 100/250 (40%) had AIMS < 5th predicting GMSS < 4 (n = 43); sensitivity, specificity, positive, and negative predictive values were 88%, 71%, 40%, and 97%. Hospitalization days were independently associated with AIMS < 5th, OR 1.02 (95% CI 1.007, 1.032; p = 0.005). Excluding hospital days, ventilation days independently predicted AIMS < 5th, OR 1.08 (95% CI 1.038, 1.125, p < 0.001. Gross motor delay determine by AIMS scores of < 5th percentile occurred in 40% of survivors with good prediction of continued delay. Delay determined by AIMS was predicted by longer hospitalization and ventilation; further investigations about the causes are required. AIMS results provide opportunity for early motor intervention.

Objectives: In infants with single-ventricle congenital heart disease, prematurity and low weight at the time of the Norwood operation are risk factors for mortality. Reports assessing outcomes (including neurodevelopment) post Norwood palliation in infants ≤2.5 kg are limited. Methods: All infants who underwent a Norwood-Sano procedure between 2004 and 2019 were identified. Infants ≤2.5 kg at the time of the operation (cases) were matched 3:1 with infants >3.0 kg (comparisons) for year of surgery and cardiac diagnosis. Demographic and perioperative characteristics, survival, and functional and neurodevelopmental outcomes were compared. Results: Twenty-seven cases (mean ± standard deviation: weight 2.2 ± 0.3 kg and age 15.6 ± 14.1 days at surgery) and 81 comparisons (3.5 ± 0.4 kg and age 10.9 ± 7.9 days at surgery) were identified. Post-Norwood, cases had a longer time to lactate ≤2 mmol/L (33.1 ± 27.5 vs 17.9 ± 12.2 hours, P < .001), longer duration of ventilation (30.5 ± 24.5 vs 18.6 ± 17.5 days, P = .005), greater need for dialysis (48.1% vs 19.8%, P = .007), and greater need for extracorporeal membrane oxygenation support (29.6% vs 12.3%, P = .004). Cases had significantly greater postoperative (in-hospital) (25.9% vs 1.2%, P < .001) and 2-year (59.2% vs 11.1%, P < .001) mortality. Neurodevelopmental assessment showed the following for cases versus comparisons, respectively: cognitive delay (18.2% vs 7.9%, P = .272), language delay (18.2% vs 11.1%, P = .505), and motor delay (27.3% vs 14.3%, P = .013). Conclusions: Infants ≤2.5 kg at Norwood-Sano palliation have significantly increased postoperative morbidity and mortality up to 2-year follow-up. Neurodevelopmental motor outcomes were worse in these infants. Additional studies are warranted to assess the outcome of alternative medical and interventional treatment plans in this patient population.
RESUMO
OBJECTIVE: To determine the 2-year neurodevelopmental outcomes for survivors of neonatal cardiac surgery for the most common right ventricular outflow tract obstructive lesions: tetralogy of Fallot and pulmonary atresia with a ventricular septal defect. STUDY DESIGN: A single-center consecutive cohort of 77 children underwent neonatal surgery for tetralogy of Fallot or pulmonary atresia with a ventricular septal defect at ≤6 weeks of age between 2006 and 2017. The patients underwent a multidisciplinary neurodevelopmental assessment at 18-24 months of age. Survivor outcomes were compared by univariable and multivariable analyses. RESULTS: The 2-year mortality was 7.8% (6/77) with a postoperative in-hospital mortality of 3.9% (3/77). Freedom from reintervention by cardiac catheterization or surgical intervention at 2 years was 36%. Functional and neurodevelopmental assessment for 69 of 71 survivors was completed at a mean age of 22.6 ± 4.0 months using the Bayley Scales of Infant and Toddler Development III. The mean neurodevelopmental outcome scores were 83.4 ± 16.5 for cognitive skills, 82.2 ± 18.7 for language skills, and 81.4 ± 18.1 for motor skills. Cognitive, language, and motor delay, defined as a score of <70, was identified in 25%, 25%, and 23% of patients, respectively. Multivariable analyses for factors associated with worse neurodevelopmental outcomes identified chromosomal anomalies (P < .001) and postoperative complications (P < .03). CONCLUSIONS: Cyanotic tetralogy of Fallot and pulmonary atresia with ventricular septal defect requiring neonatal repair showed similar 2-year neurodevelopmental outcomes below normative values and a high prevalence of cognitive, language and motor delays.

Major congenital heart disease (CHD) is associated with impaired neurodevelopment (ND), partly from prenatal insults. In this study we explore associations between 2nd and 3rd trimester umbilical (UA) and middle cerebral artery (MCA) pulsatility index (PI = systolic-diastolic velocities/mean velocity) in fetuses with major CHD and 2-year ND and growth outcomes. Eligible patients included those with a prenatal diagnosis of CHD from 2007 to 2017 without a genetic syndrome who underwent previously defined cardiac surgeries and 2-year biometric and ND assessments in our program. UA and MCA-PI Z-scores at fetal echocardiography were examined for relationships with 2-year Bayley Scales of Infant and Toddler Development and biometric Z-scores. Data from 147 children was analyzed. Second and 3rd trimester fetal echocardiograms were performed at 22.4 ± 3.7 and 34.7 ± 2.9 weeks (mean ± SD), respectively. Multivariable regression analysis showed an inverse relationship between 3rd trimester UA-PI for all CHD and cognitive - 1.98 (- 3.37, - 0.59), motor - 2.57 (- 4.15, - 0.99), and language - 1.67 (- 3.3, - 0.03) (effect size and 95th confidence interval) ND domains (p < 0.05), with the strongest relationships in the single ventricle and hypoplastic left heart syndrome subgroups. No association was found for 2nd trimester UA-PI or any trimester MCA-PI and ND or between UA or MCA-PI and 2-year growth parameters. Increased 3rd trimester UA-PI, reflecting an altered late gestation fetoplacental circulation, relates to worse 2-year ND in all domains.

BACKGROUND: We sought to evaluate the prevalence and factors associated with "optimal" neurodevelopmental outcomes in 4- to 6-year-old children with Fontan circulation. METHODS: Patients followed through the Western Canadian Complex Pediatric Therapies Follow-Up Program, and born between September 1996 and December 2015, were included. Optimal neurodevelopmental outcome was defined as full-scale intelligence quotient; visual-motor integration; adaptive behaviour assessment system-general adaptive composite scores of ≥ 80 each; and the absence of chronic motor disability, permanent hearing loss, visual impairment, and seizure disorder. Multivariable regression models and decision algorithms evaluated variables associated with optimal outcomes. RESULTS: The Fontan procedure was completed on 225 children, with neurodevelopmental outcome data available for 205 (mean [standard deviation]) age at Fontan 3.4 (0.9) years, 37% female). Optimal neurodevelopmental outcome was identified in 55% (112 of 205). Factors independently associated with optimal neurodevelopmental outcome were female sex (odds ratio [OR], 2.1; 95% confidence interval [CI] 1.1-4.1), years of maternal schooling (OR, 1.2 [1.1-1.4]), age at Fontan (years) (OR, 0.97 [0.94-1.0]), need for concomitant atrioventricular valve (AVV) intervention (OR, 0.4 [0.2-1.0]), and time (hours) for lactate to be ≤ 2 mmol/L (OR, 0.9 [0.8-1.0]). Of those with Fontan completion < 3.25 years, without concomitant AVV intervention and lactate normalization within 8 hours post-Fontan, 87% (27 of 31) had optimal neurodevelopmental outcomes. CONCLUSIONS: Optimal neurodevelopmental outcome was present in more than one-half of 4- to 6-year-old children with Fontan circulation in this cohort study, with important associated factors identified, including potentially modifiable factors such as younger age at Fontan surgery and lack of concomitant AVV intervention.

OBJECTIVES: To determine potentially modifiable risk factors for a complicated Glenn procedure (cGP) and whether a cGP predicted adverse neurodevelopmental and functional outcomes. A cGP was defined as post-operative death, heart transplant, extracorporeal life support, Glenn takedown, or prolonged ventilation. METHODS: All 169 patients having a Glenn procedure from 2012 to 2017 were included. Neurodevelopmental assessments were performed at age 2 years in consenting survivors (n = 156/159 survivors). The Bayley Scales of Infant and Toddler Development-3rd Edition (Bayley-III) and the Adaptive Behavior Assessment System-2nd Edition (ABAS-II) were administered. Adaptive functional outcomes were determined by the General Adaptive Composite (GAC) score from the ABAS-II. Predictors of outcomes were determined using univariate and multiple variable linear or Cox regressions. RESULTS: Of patients who had a Glenn procedure, 10/169 (6%) died by 2 years of age and 27/169 (16%) had a cGP. Variables statistically significantly associated with a cGP were the inotrope score on post-operative day 1 (HR 1.04, 95%CI 1.01, 1.06; p = 0.010) and use of inhaled nitric oxide post-operatively (HR 7.31, 95%CI 3.19, 16.76; p < 0.001). A cGP was independently statistically significantly associated with adverse Bayley-III Cognitive (ES -10.60, 95%CI -17.09, -4.11; p = 0.002) and Language (ES -11.43, 95%CI -19.25, -3.60; p = 0.004) scores and adverse GAC score (ES -14.89, 95%CI -22.86, -6.92; p < 0.001). CONCLUSIONS: Higher inotrope score and inhaled nitric oxide used post-operatively were associated with a cGP. A cGP was independently associated with adverse 2-year neurodevelopmental and functional outcomes. Whether early recognition and intervention for risk of a cGP can prevent adverse outcomes warrants study.

This comparison study of two groups within an inception cohort aimed to compare the frequency of motor impairment between preschool children with univentricular and biventricular critical congenital heart disease (CHD) not diagnosed with cerebral palsy/acquired brain injury, describe and compare their motor profiles and explore predictors of motor impairment in each group.Children with an intellectual quotient <70 or cerebral palsy/acquired brain injury were excluded. Motor skills were assessed with the Movement Assessment Battery for Children-2. Total scores <5th percentile indicated motor impairment. Statistical analysis included χ2 test and multiple logistic regression analysis.At a mean age of 55.4 (standard deviation 3.77) months, motor impairment was present in 11.8% of those with biventricular critical CHD, and 32.4% (p < 0.001) of those with univentricular critical CHD. The greatest difference between children with biventricular and univentricular CHD was seen in total test scores 8.73(2.9) versus 6.44(2.8) (p < 0.01) and in balance skills, 8.84 (2.8) versus 6.97 (2.5) (p = 0.001). Manual dexterity mean scores of children with univentricular CHD were significantly below the general population mean (>than one standard deviation). Independent odds ratio for motor impairment in children with biventricular critical CHD was presence of chromosomal abnormality, odds ratio 10.9 (CI 2.13-55.8) (p = 0.004); and in children with univentricular critical CHD odds ratio were: postoperative day 1-5 highest lactate (mmol/L), OR: 1.65 (C1.04-2.62) (p = 0.034), and dialysis requirement any time before the 4.5-year-old assessment, OR: 7.8 (CI 1.08-56.5) (p = 0.042).Early assessment of motor skills, particularly balance and manual dexterity, allows for intervention and supports that can address challenges during the school years.

BACKGROUND: Pediatric patients undergoing heart transplant have a number of factors predisposing them to become fluid-overloaded, including capillary leak syndrome. Capillary leak and FO are associated with organ injury and may influence both short- and long-term outcomes. This study aimed to 1) determine the extent, timing, and predictors of post-operative FO and 2) investigate the association of FO with clinically important outcomes. METHODS: Between 2000 and 2012, 70 children less than 6 years old had a heart transplant at our institution. This was a secondary analysis of data from an ongoing prospective cohort study. RESULTS: FO, defined as cumulative fluid balance greater than 10% of body weight in the first 5 post-operative days, occurred in 16/70 patients (23%); 7 of these had more than 20% FO. Shorter donor ischemic time and longer cardiopulmonary bypass time were independently associated with increased risk of FO. FO >20% was a statistically significant independent predictor of mortality (P = .005), ventilation time, and PICU length of stay. There was no statistically significant association between identified neurodevelopment domains and FO. CONCLUSIONS: Our single-center experience demonstrates that FO was common after pediatric heart transplant and was associated with worse clinical outcomes. FO is a potentially modifiable factor, and research is needed to better determine risk factors and whether intervention to reduce FO can improve outcomes in pediatric heart transplant patients.

BACKGROUND: Children with congenital heart disease (CHD) are at risk of adverse long-term neurodevelopmental outcomes, believed to be, in part, secondary to prenatal insults. Placental pathology and altered fetal middle cerebral arterial (MCA) flow suggestive of brain sparing have been documented in fetal CHD. In the present study we investigated the relationship between MCA and umbilical arterial (UA) flow patterns in fetal transposition of the great arteries (d-TGA) and hypoplastic left heart syndrome (HLHS) and growth and 2-year neurodevelopmental outcomes. METHODS: We included children with d-TGA and HLHS who had third-trimester fetal echocardiograms between 2004 and 2014, at which time umbilical artery (UA) and MCA pulsatility indices (PIs) were measured, and who underwent 2-year growth and neurodevelopmental assessments. RESULTS: We identified 24 children with d-TGA and 36 with HLHS. Mean age at fetal echocardiography was 33.8 ± 3.5 weeks. At 2-year follow-up, head circumference z score (standard deviation [SD]) was -0.09 (1.07) and 0.17 (1.7) for the d-TGA and HLHS groups, respectively. Bayley III mean (SD) cognitive, language, and motor scores were 97.7 (10.8), 94.7 (13.4), and 98.6 (8.6) for the d-TGA group and 90.3 (13.9), 87.2 (17.5), and 85.3 (16.2) for the HLHS group. On multivariate linear regression analysis, UA-PI was associated (effect sizes [95% CI]) with length (-1.45 [-2.7, -0.17], P = 0.027), weight (-1.46 [-2.6 to -0.30], P = 0.015) and cognitive scores (-14.86 [-29.95 to 0.23], P = 0.05) at 2 years of age. MCA PI showed no statistically significant correlation. CONCLUSIONS: In fetal d-TGA and HLHS, a higher UA-PI in the third trimester, suggestive of placental insufficiency-but not MCA-PI-is associated with worse 2-year growth and neurodevelopment.

BACKGROUND: There is limited information about HRQL after pediatric heart transplantation at a young age. METHODS: Prospective follow-up study of children who received a heart transplant at age ≤4 years. HRQL was assessed using the PedsQLTM 4.0 at age 4.5 years. This cohort was compared with healthy children, children with CHD, and with chronic conditions. Peri-operative factors associated with HRQL were also explored. RESULTS: Of 66 eligible patients, 15 (23%) died prior to the HRQL assessment and 2 (3%) were lost to follow-up, leaving 49 patients. Indication for transplantation was CHD in 27 (55%) and CMP in 22 (45%). Median age (IQR) at transplant was 9 (5-31) months. HRQL was significantly lower in transplanted children compared to population norms (65.3 vs 87.3, P < .0001), children with chronic conditions (65.3 vs 76.1, P = .001), and children with CHD (65.3 vs 81.1, P < .0001). Transplanted children with CHD had lower HRQL than those with a prior diagnosis of CMP (59.5 vs 72.5, P-value = .020). Higher creatinine pretransplant and higher lactate post-operatively were associated with lower HRQL. CONCLUSION: Children after heart transplant had significantly lower HRQL, as reported by their parents, than the normative population, children with chronic conditions, and children with CHD.

BACKGROUND: Urea cycle disorders (UCD) and organic acid disorders classically present in the neonatal period. In those who survive, developmental delay is common with continued risk of regression. Liver transplantation improves the biochemical abnormality and patient survival is good. We report the neurocognitive and functional outcomes post-transplant for nine UCD, three maple syrup urine disease, and one propionic acidemia patient. METHODS: Thirteen inborn errors of metabolism (IEM) patients were individually one-to-two matched to 26 non-IEM patients. All patients received liver transplant. Wilcoxon rank sum test was used to compare full-scale intelligence-quotient (FSIQ) and Adaptive Behavior Assessment System-II General Adaptive Composite (GAC) at age 4.5 years. Dichotomous outcomes were reported as percentages. RESULTS: FSIQ and GAC median [IQR] was 75 [54, 82.5] and 62.0 [47.5, 83] in IEM compared with 94.5 [79.8, 103.5] and 88.0 [74.3, 97.5] in matched patients (P-value <.001), respectively. Of IEM patients, 6 (46%) had intellectual disability (FSIQ and GAC <70), 5 (39%) had autism spectrum disorder, and 1/13 (8%) had cerebral palsy, compared to 1/26 (4%), 0, 0, and 0% of matched patients, respectively. In the subgroup of nine with UCDs, FSIQ (64[54, 79]), and GAC (56[45, 75]) were lower than matched patients (100.5 [98.5, 101] and 95 [86.5, 99.5]), P = .005 and .003, respectively. CONCLUSION: This study evaluated FSIQ and GAC at age 4.5 years through a case-comparison between IEM and matched non-IEM patients post-liver transplantation. The neurocognitive and functional outcomes remained poor in IEM patients, particularly in UCD. This information should be included when counselling parents regarding post-transplant outcome.
RESUMO
Background Management of patients with hypoplastic left heart syndrome has benefited from advancements in medical and surgical care. Outcomes have improved, although survival and long-term functional and cognitive deficits remain a concern. Methods and Results This is a cohort study of all consecutive patients with hypoplastic left heart syndrome undergoing surgical palliation at a single center. We aimed to examine demographic and perioperative factors from each surgical stage for their association with survival and neurocognitive outcomes. A total of 117 consecutive patients from 1996 to 2010 underwent surgical palliation. Seventy patients (60%) survived to the Fontan stage and 68 patients (58%) survived to undergo neurocognitive assessment at a mean (SD) age of 56.6 months (6.4 months). Full-scale, performance, and verbal intelligence quotient, as well as visual-motor integration mean (SD) scores were 86.7 (16.1), 86.3 (15.8), 88.8 (17.2), and 83.2 (14.8), respectively. On multivariable analysis, older age at Fontan, sepsis peri-Norwood, lowest arterial partial pressure of oxygen postbidirectional cavopulmonary anastomosis, and presence of neuromotor disability pre-Fontan were strongly associated with lower scores for all intelligence quotient domains. Older age at Fontan and sepsis peri-Norwood remained associated with lower scores for all intelligence quotient domains in a subgroup analysis excluding patients with disability pre-Fontan or with chromosomal abnormalities. Conclusions Older age at Fontan and sepsis are among independent predictors of poor neurocognitive outcomes for patients with hypoplastic left heart syndrome. Further studies are required to identify the appropriate age range for Fontan completion, balancing a lower risk of acute and long-term hemodynamic complications while optimizing long-term neurocognitive outcomes.

Background: Compared with those born at term gestation, infants with complex congenital heart defects (CCHD) who were delivered before 37 weeks gestational age and received neonatal open-heart surgery (OHS) have poorer neurodevelopmental outcomes in early childhood. We aimed to describe the growth, disability, functional, and neurodevelopmental outcomes in early childhood of preterm infants with CCHD after neonatal OHS. Prediction models were evaluated at various timepoints during hospitalization which could be useful in the management of these infants. Study Design: We studied all preterm infants with CCHD who received OHS within 6 weeks of corrected age between 1996 and 2016. The Western Canadian Complex Pediatric Therapies Follow-up Program completed multidisciplinary comprehensive neurodevelopmental assessments at 2-year corrected age at the referral-site follow-up clinics. We collected demographic and acute-care clinical data, standardized age-appropriate outcome measures including physical growth with calculated z-scores; disabilities including cerebral palsy, visual impairment, permanent hearing loss; adaptive function (Adaptive Behavior Assessment System-II); and cognitive, language, and motor skills (Bayley Scales of Infant and Toddler Development-III). Multiple variable logistic or linear regressions determined predictors displayed as Odds Ratio (OR) or Effect Size (ES) with 95% confidence intervals. Results: Of 115 preterm infants (34 ± 2 weeks gestation, 2,339 ± 637 g, 64% males) with CCHD and OHS, there were 11(10%) deaths before first discharge and 21(18%) deaths by 2-years. Seven (6%) neonates had cerebral injuries, 7 had necrotizing enterocolitis; none had retinopathy of prematurity. Among 94 survivors, 9% had cerebral palsy and 6% had permanent hearing loss, with worse outcomes in those with syndromic diagnoses. Significant predictors of mortality included birth weight z-score [OR 0.28(0.11,0.72), P = 0.008], single-ventricle anatomy [OR 5.92(1.31,26.80), P = 0.021], post-operative ventilation days [OR 1.06(1.02,1.09), P = 0.007], and cardiopulmonary resuscitation [OR 11.58 (1.97,68.24), P = 0.007]; for adverse functional outcome in those without syndromic diagnoses, birth weight 2,000-2,499 g [ES -11.60(-18.67, -4.53), P = 0.002], post-conceptual age [ES -0.11(-0.22,0.00), P = 0.044], post-operative lowest pH [ES 6.75(1.25,12.25), P = 0.017], and sepsis [ES -9.70(-17.74, -1.66), P = 0.050]. Conclusions: Our findings suggest preterm neonates with CCHD and early OHS had significant mortality and morbidity at 2-years and were at risk for cerebral palsy and adverse neurodevelopment. This information may be important for management, parental counseling and the decision-making process.
RESUMO
BACKGROUND: We aimed to describe school-entry age neurocognitive, functional, and HRQL outcomes and their predictors after liver transplant done at age <6 years. METHODS: A prospective cohort of all (n = 69) children surviving liver transplant from 1999 to 2014 were assessed at age 55.4 (SD 7.2) months and 38.6 (12.4) months after transplant. Assessment included: the Wechsler Preschool and Primary Scales of Intelligence, Beery-Buktenica Developmental Test of VMI, Adaptive Behavior Assessment System caregiver-completed questionnaire, and PedsQL 4.0 Generic Core Scales. Univariate and multiple linear regression determined predictors of outcomes at P < .05. RESULTS: Neurocognitive and functional outcomes were on average within 1 SD of population norms, although shifted to the left (P ≤ .03), with more patients than expected having scores >2 (3.7-5.9 times more, P ≤ .007) SD below population norms. Total and Summary HRQL scores were statistically significantly lower than the healthy normative population (P ≤ .02) and a congenital heart disease group (P ≤ .02), but similar to children with other chronic health conditions; differences often exceeded the MCID and were lowest in the School functioning domain. There were few predictors on multiple linear regressions, and we could not confirm previous studies that suggested various inconsistent predictors of outcomes. Neurocognitive and functional outcomes scores were highly correlated with HRQL scores except for the School functioning domain, but did not fully explain them. CONCLUSIONS: Long-term follow-up of this vulnerable population is important in order to facilitate support for the patient and family, and early intervention for any difficulties identified.

BACKGROUND: Clinicians often use information about developmental outcomes in decision-making around offering complex, life-saving interventions in children such as dialysis and renal transplant. This information in children with end-stage renal disease (ESRD) is limited, particularly when ESRD onset is in infancy or early childhood. METHODS: Using data from an ongoing prospective, longitudinal, inception cohort study of children with renal transplant before 5 years of age, we evaluated (1) the risk of adverse neurocognitive and functional outcomes at 5 years of age and (2) predictors of developmental outcomes. RESULTS: We found evidence of neurocognitive sequelae of ESRD in very young children; however, developmental outcomes appear remarkably better when compared with findings of two or three decades ago. Less time on dialysis predicted higher developmental scores, and hemodialysis was associated with poorer developmental outcomes. CONCLUSIONS: Our data suggest that renal replacement therapies in young children are associated with acceptable developmental outcome. Programs to identify those with developmental delays and provide early intervention may allow achievement of the child's full potential.

OBJECTIVE: To reduce bilateral delayed-onset progressive sensory permanent hearing loss using a systems-wide quality improvement project with adherence to best practice for the administration of furosemide. DESIGN: Prospective cohort study with regular audiologic follow-up assessment of survivors both before and after a 2007-2008 quality improvement practice change. SETTING: The referral center in Western Canada for complex cardiac surgery, with comprehensive multidisciplinary follow-up by the Complex Pediatric Therapies Follow-up Program. PATIENTS: All consecutive patients having single-ventricle palliative cardiac surgery at age 6 weeks old or younger. INTERVENTIONS: A 2007-2008 quality improvement practice change consisted of a Parenteral Drug Monograph revision indicating slow IV administration of furosemide, an educational program, and an evaluation. MEASUREMENTS AND MAIN RESULTS: The outcome measure was the prevalence of permanent hearing loss by 4 years old. Firth multiple logistic regression compared pre (1996-2008) to post (2008-2012) practice change occurrence of permanent hearing loss, adjusting for confounding variables, including all hospital days, extracorporeal membrane oxygenation, cardiopulmonary bypass time, age at first surgery, dialysis, and sepsis. From 1996 to 2012, 259 infants had single-ventricle palliative surgery at age 6 weeks old or younger, with 173 (64%) surviving to age 4 years. Of survivors, 106 (61%) were male, age at surgery was 11.6 days (9.0 d), and total hospitalization days by age 4 years were 64 (42); 18 (10%) had cardiopulmonary resuscitation and 38 (22%) had sepsis at any time. All 173 (100%) had 4-year follow-up. Pre- to postpractice change permanent hearing loss dropped from 17/100 (17%) to 0/73 (0%) of survivors. On Firth multiple logistic regression, the only variable statistically associated with permanent hearing loss was the pre- to postpractice change time period (odds ratio, 0.03; 95% CI, 0-0.35; p = 0.001). CONCLUSIONS: A practice change to ensure slow IV administration of furosemide eliminated permanent hearing loss. Centers caring for critically ill infants, particularly those with single-ventricle anatomy or hypoxia, should review their drug administration guidelines and adhere to best practice for administration of IV furosemide.

BACKGROUND: We aimed to determine predictors of, and outcomes after, veno-arterial extracorporeal membrane oxygenation instituted within 48 h after cardiac surgery (early ECMO) in young infants. METHODS: Patients ≤ 6 weeks old having cardiac surgery from 2003 to 2012 were enrolled prospectively. Patients cannulated pre-operatively, intra-operatively, or ≥ 48 h post-operatively were excluded. Variables at p ≤ 0.1 on univariate regression were entered into multiple logistic regression to predict early ECMO. Early-ECMO cases were matched 1:2 for six demographic variables, and death by age 2 years old (determined using conditional logistic regression; presented as odds ratio (OR), 95% confidence interval (CI)) and General Adaptive Composite scores at age 2 years (determined using Wilcoxon rank sum) were compared; p ≤ 0.05 was considered statistically significant. RESULTS: Of 565 eligible patients over the 10-year period, 20 had early ECMO instituted at a mean (standard deviation) of 12.4 (11.4) h post-operatively, 10 of whom had extracorporeal cardiopulmonary resuscitation. Of early-ECMO patients, 8 (40%) were found to have residual anatomic defects requiring intervention with catheterization (n = 1) and/or surgery (n = 7). On multiple regression, the post-operative day 1 highest vasoactive-inotrope score (OR 1.02; 95%CI 1.06,1.08; p < 0.001), highest lactate (OR 1.2; 95%CI 1.06,1.35; p = 0.003), and lowest base deficit (OR 0.82; 95%CI 0.71,0.94; p = 0.004), CPB time (OR 1.01; 95%CI 1.00,1.02; p = 0.002), and single-ventricle anatomy (OR 5.35; 95%CI 1.66,17.31; p = 0.005) were associated with early ECMO. Outcomes at 2 years old compared between early-ECMO and matched patients were mortality 11/20 (55%) vs 11/40 (28%) (OR 3.22, 95%CI 0.98,10.63; p = 0.054) and General Adaptive Composite median 65 [interquartile range (IQR) 58, 81.5] in 9 survivors vs 93 [IQR 86.5, 102.5] in 29 survivors (p = 0.02). CONCLUSIONS: The identified risk factors for, and outcomes after, having early ECMO may aid decision making in the acute period and confirm that neurodevelopmental follow-up for these children is necessary. The hypothesis that earlier institution of ECMO may improve long-term outcomes requires further study.
RESUMO
Functional abilities are needed for activities of daily living. In general, these skills expand with age. We hypothesised that, in contrast to what is normally expected, children surviving the Fontan may have deterioration of functional abilities, and that peri-Fontan stroke is associated with this deterioration. All children registered in the Western Canadian Complex Pediatric Therapies Follow-up Program who survived a Fontan operation in the period 1999-2016 were eligible for inclusion. At the age of 2 years (pre-Fontan) and 4.5 years (post-Fontan), the Adaptive Behavior Assessment System-II general adaptive composite score was determined (population mean: 100, standard deviation: 15). Deterioration of functional abilities was defined as ⩾1 standard deviation decrease in pre- to post-Fontan scores. Perioperative strokes were identified through chart review. Multivariable logistic regression analysis determined predictors of deterioration of functional abilities. Of 133 children, with a mean age at Fontan of 3.3 years (standard deviation 0.8) and 65% male, the mean (standard deviation) general adaptive composite score was 90.6 (17.5) at 2 years and 88.3 (19.1) at 4.5 years. After Fontan, deterioration of functional abilities occurred in 34 (26%) children, with a mean decline of 21.8 (7.1) points. Evidence of peri-Fontan stroke was found in 10 (29%) children who had deterioration of functional abilities. Peri-Fontan stroke (odds ratio 5.00 (95% CI 1.74, 14.36)) and older age at Fontan (odds ratio 1.67 (95% CI 1.02, 2.73)) predicted functional deterioration. The trajectory of functional abilities should be assessed in this population, as more than 25% experience deterioration. Efforts to prevent peri-Fontan stroke, and to complete the Fontan operation at an earlier age, may lead to reduction of this deterioration.
