RESUMEN
AIM: To investigate the evolution of clinical symptoms of COVID-19 in children throughout the pandemic. METHODS: In this national prospective surveillance study, symptoms in children hospitalised with COVID-19 were collected from all paediatric hospitals in Switzerland between March 2020 and March 2023. Data was analysed across four time periods, according to the predominantly circulating SARS-CoV-2 variant: T1 (wild-type), T2 (Alpha), T3 (Delta) and T4 (Omicron), as well as by age group. RESULTS: The study included 1323 children. The proportion of children admitted to an intensive care unit remained stable throughout the pandemic. However, the pattern and frequency of clinical manifestations changed over time. Respiratory symptoms were less prevalent during T1 (wild-type), fever during T2 (Alpha) and rash during T4 (Omicron). In contrast, fever and neurological symptoms were more prevalent during T4 (Omicron). Newly described symptoms during T4 (Omicron) included conjunctivitis, laryngotracheitis and seizures. Fever was more prevalent among neonates and infants whereas respiratory symptoms were more common among infants. Gastrointestinal symptoms were more frequent among toddlers, while both toddlers and school-aged children presented with neurological symptoms more often than other age groups. CONCLUSION: Continuous surveillance is required to detect changes in manifestations and there by be prepared for the optimal management of complications in children with COVID-19.

AIM: We investigated the association between early amplitude-integrated electroencephalography (aEEG) and cognitive outcome in very preterm infants at early school-age. METHODS: This prospective cohort study, conducted in the Department of Neonatology, University Hospital Zurich, Switzerland, from 2009 to 2012, comprised of infants born at <32 weeks of gestation, who underwent continuous aEEG recording during the first 4 days of life. Cognitive outcome was assessed with the Kaufman-Assessment Battery for Children at 5 years. Univariate and multivariate logistic regressions were calculated between aEEG parameters and normal cognitive outcome, defined as an intelligence quotient (IQ) of at least 85. RESULTS: The 118 (52.5% male) infants were born at a mean gestational age of 29.9 weeks and a mean birth weight of 1235 ± 363 g. We followed up 89 children at the age of five, and they had a mean IQ of 97.8 ± 12.7 with 21.3% under 85-and 2.2% had cerebral palsy. Univariate analyses found associations between aEEG measures and normal cognitive outcome, but these were no longer significant after adjustment for confounders. Socioeconomic status and neonatal morbidity were independent predictors of cognitive outcome. CONCLUSION: Early short-term aEEG did not predict later cognitive outcome in our cohort of very preterm infants.

INTRODUCTION: The Management of Myelomeningocele Study, a.k.a. the MOMS trial, was published in 2011 in the New England Journal of Medicine. This prospective randomized controlled trial proved to be a milestone publication that provided definitive evidence that fetal surgery is a novel standard of care for select fetuses with spina bifida aperta (SB). The goal of our study is to assess whether our center can match these benchmark results. MATERIALS AND METHODS: Our study was conducted according to the MOMS protocol using the same inclusion and exclusion criteria and looked at the same outcome parameters that were used in the MOMS trial. Zurich and MOMS results were compared. RESULTS: We enrolled 20 patients between December 2010 and May 2015 all of whom underwent fetal surgery for SB. Among 51 different outcome variables, there were only 3 favorable (multiplicity-adjusted) significant differences (gestational age at birth, hindbrain herniation, and psychomotor development). There were no statistically significant differences regarding any other parameters. CONCLUSION: Our findings confirm that rigorous apprenticeship, training, and comprehensive prospective data collection enable centers like the Zurich Center for Fetal Diagnosis and Therapy to achieve benchmark results for open fetal surgery for myelomeningocele and myeloschisis. These results justify the existence and continuation of our program. Outcome documentation is an essential element of quality management. It is medically and ethically fundamental for fetal medicine and surgery centers offering high-end innovative medical care.

OBJECTIVE: To determine growth and its relationship to IQ in children with congenital heart disease (CHD) undergoing cardiopulmonary bypass surgery within the first year of life. STUDY DESIGN: Prospective single-center cohort study on 143 children (91 males) with different types of CHD (29 univentricular). Children with recognized genetic disorders were excluded. Growth (weight, height, and head circumference [HC]) was assessed at birth, before surgery, and at 1, 4, and 6 years and compared with Swiss growth charts. IQ was assessed at 6 years using standardized tests. Univariate and multivariable linear regressions were performed to determine predictors of HC and IQ at 6 years. RESULTS: HC at birth was in the low average range (33rd percentile, P = .03), and weight (49th percentile, P = .23) and length (47th percentile, P = .06) were normal. All growth measures declined until the first surgery, with a catch-up growth until 6 years for height (44th percentile, P = .07) but not for weight (39th percentile, P = .003) or for HC (23rd percentile, P < .001). Children undergoing univentricular palliation showed poorer height growth than other types of CHD (P = .01). Median IQ at 6 years was 95 (range 50-135). Lower IQ at 6 years was independently predicted by lower HC at birth, lower socioeconomic status, older age at first bypass surgery, and longer length of intensive care unit stay. CONCLUSIONS: Smaller HC at birth and postnatal factors are predictive of impaired intellectual abilities at school age. Early identification should alert clinicians to provide early childhood interventions to optimize developmental potential.

BACKGROUND: Paediatric end-of-life care is challenging and requires a high level of professional expertise. It is important that healthcare teams have a thorough understanding of paediatric subspecialties and related knowledge of disease-specific aspects of paediatric end-of-life care. The aim of this study was to comprehensively describe, explore and compare current practices in paediatric end-of-life care in four distinct diagnostic groups across healthcare settings including all relevant levels of healthcare providers in Switzerland. METHODS: In this nationwide retrospective chart review study, data from paediatric patients who died in the years 2011 or 2012 due to a cardiac, neurological or oncological condition, or during the neonatal period were collected in 13 hospitals, two long-term institutions and 10 community-based healthcare service providers throughout Switzerland. RESULTS: Ninety-three (62%) of the 149 reviewed patients died in intensive care units, 78 (84%) of them following withdrawal of life-sustaining treatment. Reliance on invasive medical interventions was prevalent, and the use of medication was high, with a median count of 12 different drugs during the last week of life. Patients experienced an average number of 6.42 symptoms. The prevalence of various types of symptoms differed significantly among the four diagnostic groups. Overall, our study patients stayed in the hospital for a median of six days during their last four weeks of life. Seventy-two patients (48%) stayed at home for at least one day and only half of those received community-based healthcare. CONCLUSIONS: The study provides a wide-ranging overview of current end-of-life care practices in a real-life setting of different healthcare providers. The inclusion of patients with all major diagnoses leading to disease- and prematurity-related childhood deaths, as well as comparisons across the diagnostic groups, provides additional insight and understanding for healthcare professionals. The provision of specialised palliative and end-of-life care services in Switzerland, including the capacity of community healthcare services, need to be expanded to meet the specific needs of seriously ill children and their families.

OBJECTIVES: To assess 6-year neurodevelopmental outcomes in a current cohort of children with congenital heart disease (CHD) who underwent cardiopulmonary bypass surgery (CPB), and to determine risk factors for adverse outcomes. STUDY DESIGN: Outcomes were examined in 233 prospectively enrolled children with CHD (including 64 with a recognized genetic disorder) who underwent CPB between 2004 and 2009. Follow-up assessment included standardized neurologic, motor, and cognitive tests. Variables were collected prospectively, and multiple regression analysis was performed to determine independent risk factors for adverse outcome. RESULTS: The mean patient age at assessment was 6.3 years (range, 5.1-6.8 years). IQ was lower in children with a genetic disorder (median, 55; range, 17-115) compared with children without a genetic disorder (median, 95; range, 47-135; P < .001). Cognitive and motor performance also were lower in children without a genetic disorder compared with the norm (P < .01 for both). The prevalence of children without a genetic disorder performing below -2 SD (IQ 70) was higher than the norm (5.3% vs 2.3%; P = .008), and the prevalence of poor motor performance (<10th percentile) ranged from 21.2% to 41.1% (P < .01 for all). Significant independent risk factors for poor neurodevelopmental outcome included a genetic disorder, longer length of intensive care stay, lower birth weight, postoperative seizures, and lower socioeconomic status. CONCLUSIONS: Current cohorts of children with CHD undergoing CPB show favorable outcomes but remain at risk for long-term neurodevelopmental impairments, particularly those with a genetic disorder and a complicated postoperative course. Close neurodevelopmental surveillance is necessary to provide early therapeutic support.

AIMS AND OBJECTIVES: To investigate parents' experiences, coping ability and quality of life while monitoring their sick child with hypoplastic left heart syndrome at home. BACKGROUND: Interstage home monitoring for children with hypoplastic left heart syndrome reduces interstage mortality between Norwood stages I and II. Little is known about the psychosocial impact of interstage home monitoring. DESIGN: Prospective mixed-method study. METHODS: This study assessed the psychosocial impact on parents during interstage home monitoring. This contains for quantitative assessment the Short Form Health Survey questionnaire and the Impact of Family Scale administered one and five weeks following discharge before and after stage II. For qualitative assessment, semi-structured interviews focussing on the postdischarge coping strategies were conducted twice, five weeks after hospital discharge before and after stage II. RESULTS: Ten infants (eight males) with hypoplastic left heart syndrome (n = 7) or other types of univentricular heart malformations (n = 3), and their parents (nine mother/father two-parent households, one single mother) were included. There were no interstage deaths. Mental Health Composite Summary scores were low in both parents (mothers: 40·45 ± 9·07; fathers: 40·58 ± 9·69) and lowest for the item 'vitality' (mothers: 37·0 ± 19·46; fathers: 43·12 ± 25·9) before and after stage II. Impact of Family Scale values showed higher daily and social burdens for mothers. 'Becoming a family' was the most important task as coping strategy to equilibrate the fragile emotional balance. The parents judged interstage home monitoring as a protective intervention. CONCLUSIONS: Although psychosocial burden before and after stage II remains high, becoming a family is an essential experience for parents and confirms their parenthood. RELEVANCE TO CLINICAL PRACTICE: Healthcare professionals must be aware of parents' needs during this vulnerable interstage period and to provide psychosocial and nursing support.

OBJECTIVES: To evaluate the predictive value of pre- and postoperative amplitude-integrated electroencephalography (aEEG) on neurodevelopmental outcomes in children operated for congenital heart disease (CHD). STUDY DESIGN: Prospectively enrolled cohort of 60 infants with CHD who underwent cardiac surgery with cardiopulmonary bypass in the first 3 months of life. Infants with a genetic comorbidity were excluded. aEEG was assessed for 12 hours pre- and 48 hours postoperatively. Background pattern was classified by the use of standard categories, and the presence of seizures and sleep-wake cycles (SWCs) was noted. Outcome at 1 and 4 years of age was assessed with standardized developmental tests. RESULTS: Preoperatively, infants either showed continuous normal voltage (n = 56) or discontinuous normal voltage (n = 4). Postoperatively, abnormal background pattern (flat trace, burst suppression, or continuous low voltage) was detected in 7 (12%), discontinuous normal voltage in 37 (61%), and continuous normal voltage in 16 (27%) infants. Nineteen infants (32%) did not return to normal SWCs within the recording period. Seizures were detected in 4 infants preoperatively and in another 4 postoperatively. After we controlled for surgical and postoperative risk factors, abnormal postoperative background pattern and lack of return to SWCs independently predicted poorer intelligence quotient at 4 years (P = .03 and P = .04 respectively) but was not related to motor outcome. CONCLUSION: aEEG is a useful bedside tool that helps to predict outcome in infants undergoing open-heart surgery for CHD. Abnormal postoperative background pattern and lack of return to SWCs are markers for subsequent impaired cognitive development.

OBJECTIVES: To present our experience in an interdisciplinary and interprofessional morbidity and mortality conference, with special emphasis on its usefulness in improving patient safety. DESIGN: Retrospective analysis. SETTING: Tertiary interdisciplinary neonatal PICU. PATIENTS: Morbidity and mortality conference minutes on 48 patients (newborns to 17 yr), January 2009 to June 2014. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The authors' PICU implemented a morbidity and mortality conference guideline in 2009 using a system-based approach to identify medical errors, their contributing factors, and possible solutions. In the subsequent 5.5 years, there were 44 mortality conferences (of 181 deaths [27%] over the same period) and four morbidity conferences. The median death/morbidity event-morbidity and mortality conference interval was 90 days (range, 7 d to 1.5 yr). The median age of patients was 4 months (range, newborn to 17 years). In six cases, the primary reason for PICU admission was a treatment complication. Unsafe processes/medical errors were identified and discussed in 37 morbidity and mortality conferences (77%). In seven cases, new autopsy findings prompted the discussion of a possible error. The 48 morbidity and mortality conferences identified 50 errors, including 30 in which an interface problem was a contributing factor. Fifty-four improvements were identified in 34 morbidity and mortality conferences. Four morbidity and mortality conferences discussed specific ethical issues. CONCLUSIONS: From our experience, we have found that the interdisciplinary and interprofessional morbidity and mortality conference has the potential to reveal unsafe processes/medical errors, in particular, diagnostic and communication errors and interface problems. When formatted as a nonhierarchical tool inviting contributions from all staff levels, the morbidity and mortality conference plays a key role in the system approach to medical errors.

OBJECTIVES: To study the long-term neurodevelopmental effects of hyperglycemia in infant bypass surgery for congenital heart disease (CHD). STUDY DESIGN: Prospective cohort study on neurodevelopmental outcome after infant cardiac bypass surgery. EXCLUSION CRITERIA: age older than 1 year at first surgery, genetic comorbidity, and birth weight <2000 g. Of 167 eligible infants, follow-up examination at 4 years was completed in 150 children (90%). Intraoperative and postoperative highest and lowest glucose levels within 24 hours after bypass surgery were prospectively collected. Neurodevelopmental outcome at 4 years of age was assessed using standardized IQ tests and the Movement Assessment Battery for Children-second version for motor outcome assessment. RESULTS: Mean age at surgery was 2.8 months (0.1-10.7 months), 33% of children had an acyanotic CHD and 67% a cyanotic CHD. Glucose levels were elevated (>8 mmol/L) in 21 (14%) children in the first 24 postoperative hours. Glucose levels normalized in all children within 48 hours, 7 children (4%) received insulin infusions. Mean total IQ was within the normal range, but significantly lower than the normal population (92.5 [SD 15.0], P < .001). Higher postoperative glucose levels were related to better cognitive performance in the univariate analysis (P < .03), but not when other risk factors were taken into account. Independent risk factors for adverse outcome were lower socioeconomic status, higher risk adjustment for congenital heart surgery score, and longer duration of intensive care stay. CONCLUSION: Hyperglycemia is common in the early postoperative course after infant bypass surgery for CHD and normalizes within 48 hours. Hyperglycemia has no adverse effect on long-term neurodevelopmental outcome.

OBJECTIVES: To determine neonatal global and regional brain volumes in infants with congenital heart disease (CHD) in comparison with healthy controls and to determine brain growth. STUDY DESIGN: Prospective cohort study in infants undergoing open-heart surgery for complex CHD. Global and regional volumetric measurements on preoperative cerebral magnetic resonance imaging were manually segmented in children without overt brain lesions. RESULTS: Preoperative brain volumetry of 19 patients demonstrates reduction in total and regional brain volumes, without any specific regional predilection compared with 19 healthy control infants (total brain volume reduction: 21%, regional brain volume reduction 8%-28%, all P < .001). CONCLUSIONS: Infants with CHD undergoing bypass surgery have smaller brain volumes prior to surgery without a specific regional predilection. This suggests a fetal origin of reduced brain growth.

AIM: To determine the role of preoperative cranial ultrasound (cUS) in predicting neurodevelopmental outcome in infants undergoing bypass surgery for congenital heart disease (CHD). METHOD: Prospective cohort study on 77 infants (44 males, 33 females) operated before 3 months of age (median age at surgery 10d [range 3-88d]) who received at least one preoperative cUS. Outcome at 1 year was assessed with a standardized neurological examination and the Bayley Scales of Infant Development II (mental developmental index [MDI]; psychomotor developmental index [PDI]). RESULTS: Abnormalities on cUS were detected in 22 (29%) infants and consisted of diffuse brain oedema (n=12, 16%), periventricular white matter injury (n=5, 6%), ventricular dilatation (n=3, 4%), and intraventricular haemorrhage (IVH) (n=2, 3%). Infants undergoing balloon-atrial septostomy (BAS) had a higher rate of subsequent brain oedema than those without BAS (p=0.006). cUS abnormalities were not related to neurodevelopmental outcome. INTERPRETATION: Preoperative cUS findings in infants undergoing bypass surgery for CHD occur rather frequently, consisting of mild lesions such as brain oedema or white matter changes. These findings, however, do not correlate with early neurodevelopmental outcome.
RESUMEN
AIMS: To determine the correlation between amplitude-integrated electroencephalogram (aEEG) background pattern and cerebral magnetic resonance imaging (MRI) in infants with hypoxic-ischaemic encephalopathy (HIE) and to examine whether the correlation changes with therapeutic hypothermia. METHODS: We included 38 term-born infants with HIE of whom 17 were cooled. All were continuously monitored with aEEG. Background pattern was scored at the beginning and the end of the recording. Cerebral MRI was obtained on median day 5 (2-11 days). Abnormalities were classified using a predefined scoring system for basal ganglia, watershed and overall injury, and then grouped into mild-moderate and severe. RESULTS: Abnormal aEEG background pattern correlated with more severe cerebral injury on MRI in the non-cooled infants (P < 0.01). In addition, cooled infants had less severe cerebral injury than non-cooled infants, in particular on T2-weighted images (watershed P = 0.04 and total injury score = 0.07). CONCLUSIONS: Abnormal aEEG background pattern is predictive of abnormal MRI, but therapeutic hypothermia seems to reduce this association. Thus, when cooling is applied in a clinical setting, the predictive value of aEEG may be limited.

BACKGROUND: Amplitude-integrated electroencephalogram (aEEG) is increasingly used for neuromonitoring in preterms. We aimed to quantify the effects of gestational age (GA), postnatal age (PNA), and other perinatal factors on the development of aEEG early after birth in very preterm newborns with normal cerebral ultrasounds. METHODS: Continuous aEEG was prospectively performed in 96 newborns (mean GA: 29.5 (range: 24.4-31.9) wk, birth weight 1,260 (580-2,120) g) during the first 96 h of life. aEEG tracings were qualitatively (maturity scores) and quantitatively (amplitudes) evaluated using preestablished criteria. RESULTS: A significant increase in all aEEG measures was observed between day 1 and day 4 and for increasing GA (P < 0.001). The effect of PNA on aEEG development was 6.4- to 11.3-fold higher than that of GA. In multivariate regression, GA and PNA were associated with increased qualitative and quantitative aEEG measures, whereas small-for-GA status was independently associated with increased maximum aEEG amplitude (P = 0.003). Morphine administration negatively affected all aEEG measures (P < .05), and caffeine administration negatively affected qualitative aEEG measures (P = 0.02). CONCLUSION: During the first few days after birth, aEEG activity in very preterm infants significantly develops and is strongly subjected to the effect of PNA. Perinatal factors may alter the early aEEG tracing and interfere with its interpretation.

INTRODUCTION: Studies have shown a high prevalence of sleep-disordered breathing (SDB) in children with spina bifida. International standards for regular testing for SDB in this population are lacking. While there are studies investigating the prevalence of SDB in children with spina bifida, there are close to no studies in neonates. AIM AND OBJECTIVE: To evaluate if routine respiratory polygraphy (RPG) testing is indicated for neonates with spina bifida and if yes, with what therapeutic consequence. METHODS: We conducted a retrospective cohort study of all neonates with spina bifida at the University (Children's) Hospital Zurich after fetal spina bifida repair born between 2017 and 2022, who had undergone at least 1 RPG evaluation during hospitalization on the neonatal ward. RPG were evaluated by a blinded group of experienced pediatric pulmonologists. Based on the neonatal RPG results and pediatric pulmonologist's recommendation for caffeine therapy the spina bifida cohort was divided into two groups. Neonatal baseline RPG and follow-up RPG at the age of the 3 months were evaluated. RESULTS: 48 neonates with RPG were included. Compared to the standard values in healthy neonates, the RPG results of this spina bifida cohort showed findings of SDB with central apnea and hypopnea. 22 (45.8%) neonatal RPG evaluations detected central SDB, prompting caffeine therapy. Follow-up RPG conducted after 3 months showed significant improvement of SDB with (almost) no need for continuation of caffeine. CONCLUSION: We recommend the implementation of routine RPG testing in neonates with spina bifida to detect SDB and facilitate early targeted treatment.
RESUMEN
AIMS: To determine the motor and cognitive outcome in a regional cohort of survivors of surgically corrected congenital diaphragmatic hernia. METHODS: Thirty-three children (85% of survivors) were examined at a mean age of 8.6 years (3.3-15.7 years), seven had a genetic comorbidity. Outcome was assessed with the Wechsler Preschool and Primary Scale of Intelligence 3rd version and the Wechsler Intelligence Scale 4th version. Motor performance was tested with the Movement Assessment Battery for Children 2nd edition in children younger than 5 years and thereafter with the Zurich Neuromotor Assessment. RESULTS: Children without a genetic comorbidity had a normal cognitive outcome (median IQ 103, 70-121), but fine motor (p = 0.008) and gross motor outcome (p = 0.001) were poorer than the norm. Medical variables were not predictive of adverse outcome, whereas genetic comorbidity was the strongest predictor of low IQ (p < 0.001) and of poor motor performance (p = 0.04). CONCLUSIONS: In the absence of a genetic comorbidity, children with congenital diaphragmatic hernia have a favourable cognitive outcome, but motor outcome may be affected. This needs to be taken into account for parental counselling. Further, long-term neurodevelopmental assessment in children with congenital diaphragmatic hernia is important to provide early therapeutic interventions.

AIMS: Peripheral cannulas in newborns are commonly used for intravenous treatment. However sustained maintenance of cannula patency is often difficult to achieve in this age group. This study compares the duration for which cannula patency can be maintained in newborns under continuous infusion, or an intermittent flushing regimen, with normal saline. METHODS: A prospective observational study was conducted during a 12-month period. All newborns admitted to the 16-bed intermediate care unit, who required intravenous treatment, received either continuous peripheral infusion with 0.9% saline at an infusion rate of 2 mL/h or an intravenous cannula, which was flushed with 1 mL of 0.9% saline at least once every 24 h. RESULTS: A total of 53 patients with 86 cannulas were included. Twenty-five (47%) patients received 41 continuous infusions. The intermittent flushing group consisted of 28 (53%) patients with 45 cannulas administered. The cannula patency was significantly longer in the intermittent flushing group (mean 62.1 vs. 92.8 h, P=0.01). The patient's underlying disease and the cannula insertion site were not related with the duration of the cannula patency. CONCLUSIONS: Our study shows that intermittent cannula flushing is associated with improved cannula patency for peripherally inserted venous catheters in newborns.

We conducted this study to compare the strong ion gap (SIG) with base excess (BE) and lactate for predicting neurologic outcome measured by magnetic resonance imaging (MRI) in newborns with hypoxic-ischemic encephalopathy (HIE). In a retrospective cohort of 39 newborns with HIE treated with whole-body surface cooling (n = 17) and no cooling (n = 22), we measured blood SIG, BE, and lactate at 4, 24, and 48 hours after birth, and determined cerebral injury severity by T1-, T2-, and diffusion-weighted MRI scores at age 5 days. Lower SIG levels correlated with better neurologic outcome. The highest correlation coefficient (0.63) was in the "no cooling" subcohort between diffusion-weighted scores and SIG levels at 24 hours; the latter also had the highest area under the receiver operating characteristic curve (AUC), 0.90, with positive and negative predictive values of 84 and 90%. SIG outperformed lactate in the "no cooling" subcohort, and vice-versa in the "cooling" subcohort. All BE AUCs were <0.6. Overall, the SIG is similar to lactate as a prognostic parameter. BE levels at 4, 24, and 48 hours after birth do not predict neurologic outcome. While not displacing lactate the SIG is an additional prognostic parameter for newborns in the first 2 days after hypoxia-ischemia.

BACKGROUND AND OBJECTIVES: Transcutaneous PCO2 and PO2 measurement systems offer non-invasive blood gas trend monitoring. The aim of this prospective study was to assess bias and precision of a transcutaneous PCO2 and PO2 measurement system incorporating a novel pO2 sensor (Sentec OxiVenT™) in neonates ≥34 weeks of gestational age (GA) admitted to intensive care. METHODS: Transcutaneous PCO2 and PO2 were compared to arterial and capillary blood gas measurements. Bias and precision were calculated by fitting linear mixed models to account for repeated measurements, and influence of clinical covariates on bias and precision was assessed. RESULTS: We obtained 611 paired transcutaneous and blood gas measurements in 110 patients (median GA 38.3 [interquartile range 36.1-39.7] weeks; age 9 [4-15] days; weight 3,000 [2,500-3,500] g). Transcutaneous PCO2 showed significant bias to arterial PCO2 (+0.61; 95% confidence interval 0.46, 0.76 kPa), but not to capillary PCO2 (-0.23; -0.46, 0.002 kPa). Bias of transcutaneous PO2 was significant to arterial PO2 (-2.50; -2.94, -2.06 kPa), while no significant bias compared to capillary PO2 was observed (+0.17; -0.30, 0.64 kPa). Precision intervals were ±1.8/2.0 kPa for arterial versus capillary PCO2 and ±4.9/3.3 kPa for arterial versus capillary PO2 comparisons, respectively. Further, sensor operating temperature (43°C vs. 42°C), soft tissue oedema, vasoactive drugs, weight, and GA significantly altered bias (p < 0.05). CONCLUSIONS: The tested transcutaneous blood gas measurement system showed no significant bias compared to capillary PCO2 and PO2, acceptable bias to arterial PCO2, and limited agreement with arterial PO2. Precision intervals were wide for all comparisons.

OBJECTIVES: Children with congenital heart disease and genetic disorders may be at increased risk for postoperative mortality and morbidity compared with children with congenital heart disease alone. The aim of the present study was to determine differences in postcardiopulmonary bypass outcome between these two groups. DESIGN: Prospective cohort study. SETTING: Tertiary university children's hospital. PATIENTS: We enrolled 211 infants (<1 yr) who underwent bypass surgery for congenital heart disease. Data on perioperative course were compared between infants with and without genetic disorders. Univariate analysis was followed by regression analysis to control for confounders. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We enrolled 148 infants without and 63 infants with a genetic disorder. The majority of infants with genetic disorders had trisomy 21 (n = 32), six had microdeletion 22q11, and 25 had other genetic disorders. There was no significant difference in mortality between infants with and without genetic disorders. An underlying genetic disorder was an independent risk factor for renal insufficiency (p = .003) and reintubation (p = .02). Trisomy 21 was an independent risk factor for chylothorax (p = .01) and sepsis (p = .05). The length of hospital stay was longer in infants with genetic disorders other than trisomy 21 compared with infants with trisomy 21 (p = .009). CONCLUSIONS: Infants with congenital heart disease and genetic disorders are not at increased risk for postoperative mortality. However, a genetic disorder is a risk factor for reintubation and renal insufficiency, whereas infants with trisomy 21 have a higher risk of chylothorax and sepsis. Intensive care providers need to be aware of these differences in morbidity to improve management decisions and parental counseling.
