RESUMEN
OBJECTIVE: The objective of this study was to characterize clinical factors associated with successful extubation in infants with congenital diaphragmatic hernia. STUDY DESIGN: Using the Children's Hospitals Neonatal Database, we identified infants with congenital diaphragmatic hernia from 2017 to 2020 at 32 centers. The main outcome was age in days at the time of successful extubation, defined as the patient remaining extubated for 7 consecutive days. Unadjusted Kaplan-Meier and multivariable Cox proportional hazards ratio equations were used to estimate associations between clinical factors and the main outcome. Observations occurred through 180 days after birth. RESULTS: There were 840 eligible neonates with a median gestational age of 38 weeks and birth weight of 3.0 kg. Among survivors (n = 693), the median age at successful extubation was 15 days (interquartile range [IQR]: 8-29 days, 95th percentile: 71 days). For nonsurvivors (n = 147), the median age at death was 21 days (IQR: 11-39 days, 95th percentile: 110 days). Center (adjusted hazards ratio: 0.22-15, P < .01), low birth weight, intrathoracic liver position, congenital heart disease, lower 5-minute Apgar score, lower pH upon admission to Children's Hospitals Neonatal Database center, and use of extracorporeal support were independently associated with older age at successful extubation. Tracheostomy was associated with multiple failed extubations. CONCLUSION: Our findings suggest that infants who have not successfully extubated by about 3 months of age may be candidates for tracheostomy with chronic mechanical ventilation or palliation. The variability of timing of successful extubation among our centers supports the development of practice guidelines after validating clinical criteria.

OBJECTIVE: Infants with congenital diaphragmatic hernia (CDH) require multiple invasive interventions carrying inherent risks, including central venous and arterial line placement. We hypothesized that specific clinical or catheter characteristics are associated with higher risk of nonelective removal (NER) due to complications and may be amenable to efforts to reduce patient harm. STUDY DESIGN: Infants with CDH were identified in the Children's Hospital's Neonatal Database (CHND) from 2010 to 2016. Central line use, duration, and complications resulting in NER are described and analyzed by extracorporeal membrane oxygenation (ECMO) use. RESULTS: A total of 1,106 CDH infants were included; nearly all (98%) had a central line placed, (average of three central lines) with a total dwell time of 22 days (interquartile range [IQR]: 14-39). Umbilical arterial and venous lines were most common, followed by extremity peripherally inserted central catheters (PICCs); 12% (361/3,027 central lines) were removed secondary to complications. Malposition was the most frequent indication for NER and was twice as likely in infants with intrathoracic liver position. One quarter of central lines in those receiving ECMO was placed while receiving this therapy. CONCLUSION: Central lines are an important component of intensive care for infants with CDH. Careful selection of line type and location and understanding of common complications may attenuate the need for early removal and reduce risk of infection, obstruction, and malposition in this high-risk group of patients. KEY POINTS: · Central line placement near universal in congenital diaphragmatic hernia infants.. · Mean of three lines placed per patient; total duration 22 days.. · Clinical patient characteristics affect risk..

OBJECTIVES: To assess the feasibility of magnetic resonance imaging (MRI) for postnatal assessment of pulmonary vascularity in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: Infants with prenatally diagnosed CDH (n = 24) received postnatal pulmonary MRI. Infants with nonpulmonary birth defects served as controls (n = 5). Semiautomatic segmentation was performed to obtain total vascular volume using time of flight images to assess vascularity. RESULTS: Average vascular density (vascular volume/lung volume) in control infants was 0.23 ± 0.06 mm3/mm3 compared with 0.18 ± 0.06 mm3/mm3 in infants with CDH is (P = .09). When stratified further based on CDH severity, the difference between control infants and moderate CDH group was statistically significant. (0.23 mm3/mm3 vs 0.15 mm3/mm3, P = .01). Ipsilateral vascular density on MRI in infants with CDH significantly correlated with the prenatal pulmonary hypertensive index (P = .0004, Spearman R = +0.87) and with number of days on mechanical ventilation (P = .04, Spearman R = -0.44), total days on inhaled nitric oxide (P = .02, Spearman R = -0.47), use of epoprostenol for acute pulmonary hypertension (PH) (0.14 mm3/mm3 vs 0.20 mm3/mm3, P = .005), and use of sildenafil for chronic PH (0.15 mm3/mm3 vs 0.19 mm3/mm3, P = .03). CONCLUSIONS: Our results suggest that postnatal pulmonary vascularity assessed by MRI strongly correlates with prenatal and postnatal markers of PH severity and that pulmonary vascularity may serve as a direct measure of pulmonary vascular hypoplasia in infants with CDH.

BACKGROUND: Outcomes of infants with congenital diaphragmatic hernia (CDH) are primarily dependent on the severity of pulmonary hypoplasia. It is previously unknown whether postnatal lung growth in infants with CDH represents true parenchymal lung growth or merely an expansion in volume of the existing tissue. We hypothesized that lung volume growth in CDH infants will be accompanied by an increase in lung mass and that CDH infants will demonstrate accelerated catch-up growth of the more hypoplastic lung. METHODS: We used fetal and post-CDH repair MRI of 12 infants to measure lung volume and density, which was used to calculate lung mass. RESULTS: The average increase in right lung mass was 1.1 ± 1.1 g/week (p = 0.003) and the average increase in left lung mass was 1.8 ± 0.7 g/week (p < 0.001). When the ratio of left-to-right lung mass of the prenatal MRI was compared to post-repair MRI, the ratio significantly increased in all infants with average prenatal and post-repair ratios of 0.30 and 0.73, respectively (p = 0.002). CONCLUSION: Lung growth in infants with CDH is indeed growth in lung mass (i.e. parenchyma), and the lungs demonstrate catch-up growth (i.e., increased rate of growth in the more hypoplastic ipsilateral lung).

OBJECTIVES: We aim to determine factors that are associated with better outcomes of CDH patients. METHODS: A retrospective review was performed on all CDH patients admitted to our institution between 2003 and 2016. This study was performed at a single institution which has a fetal care center. Patients admitted with CDH with at least 1-year follow-up during the analysis were included in the study. RESULTS: Twenty-six (13.8%) patients had a hernia sac, 124 (59%) patients had liver herniation, and 56 (25.1%) patients had an accompanying syndrome. Overall survival to discharge was 73.1% while overall survival to date was 69.5%. The presence of a hernia sac, liver herniation, and accompanying syndromes showed as independent predictors influencing the survival, B 1.968, p = 0.04, OR 7.158, 95% CI 0.907-56.485, B - 1.178, p = 0.01, OR 3.932, 95% CI 1.798-8.602 and B - 1.032, p = 0.05, OR 2.795, 95% CI 0.976-7.764, respectively. CONCLUSION: In our CDH cohort, the presence of a hernia sac was proven to be associated with better outcomes, while thoracic herniation of the liver was associated with worse outcomes. The accompanying syndromes although being more difficult to manage had a little effect on the outcome of the disease itself.

OBJECTIVE: To predict incident bloodstream infection and urinary tract infection (UTI) in infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: We conducted a retrospective analysis using the Children's Hospital Neonatal Database during 2010-2016. Infants with CDH admitted at 22 participating regional neonatal intensive care units were included; patients repaired or discharged to home prior to admission/referral were excluded. The primary outcome was death or the occurrence of bloodstream infection or UTI prior to discharge. Factors associated with this outcome were used to develop a multivariable equation using 80% of the cohort. Validation was performed in the remaining 20% of infants. RESULTS: Median gestation and postnatal age at referral in this cohort (n = 1085) were 38 weeks and 3.1 hours, respectively. The primary outcome occurred in 395 patients (36%); and was associated with low birth weight, low Apgar, low admission pH, renal and associated anomalies, patch repair, and extracorporeal membrane oxygenation (P < .001 for all; area under receiver operating curve = 0.824; goodness of fit χ2 = 0.52). After omitting death from the outcome measure, admission pH, patch repair of CDH, and duration of central line placement were significantly associated with incident bloodstream infection or UTI. CONCLUSIONS: Infants with CDH are at high risk of infection which was predicted by clinical factors. Early identification and low threshold for sepsis evaluations in high-risk infants may attenuate acquisition and the consequences of these infections.

OBJECTIVE: To evaluate postnatal lung volume in infants with congenital diaphragmatic hernia (CDH) and determine if a compensatory increase in lung volume occurs during the postnatal period. STUDY DESIGN: Using a novel pulmonary magnetic resonance imaging method for imaging neonatal lungs, the postnatal lung volumes in infants with CDH were determined and compared with prenatal lung volumes obtained via late gestation magnetic resonance imaging. RESULTS: Infants with left-sided CDH (2 mild, 9 moderate, and 1 severe) were evaluated. The total lung volume increased in all infants, with the contralateral lung increasing faster than the ipsilateral lung (mean ± SD: 4.9 ± 3.0 mL/week vs 3.4 ± 2.1 mL/week, P = .005). In contrast to prenatal studies, the volume of lungs of infants with more severe CDH grew faster than the lungs of infants with more mild CDH (Spearman's ρ=-0.086, P = .01). Although the contralateral lung volume grew faster in both mild and moderate groups, the majority of total lung volume growth in moderate CDH came from increased volume of the ipsilateral lung (42% of total lung volume increase in the moderate group vs 32% of total lung volume increase in the mild group, P = .09). Analysis of multiple clinical variables suggests that increased weight gain was associated with increased compensatory ipsilateral lung volume growth (ρ = 0.57, P = .05). CONCLUSIONS: These results suggest a potential for postnatal catch-up growth in infants with pulmonary hypoplasia and suggest that weight gain may increase the volume growth of the more severely affected lung.

OBJECTIVE: To determine whether premature infants' sleep organization, total sleep time, and arousals may be modulated while on a conformational positioner that provides boundaries, customized positioning, and containment compared with standard positioning (standard crib mattress). STUDY DESIGN: A proof of concept trial using a within subject crossover design was conducted among 25 premature infants with feeding difficulties. Infants of 31.5 weeks gestational age served as their own control during overnight polysomnography at postconceptual age 38.4 weeks. Each baby received both interventions (order randomized), 1 for each one-half of the 10.5-hour study. RESULTS: Use of the conformational positioner resulted in higher sleep efficiency of 61% vs 54% for the standard mattress (P < .05). The interventions did not differ for percent active sleep, percent quiet sleep, percent indeterminate sleep, or spontaneous arousals. Sleep efficiency was higher on the conformational positioner than standard positioning for surgical subjects and for subjects with necrotizing enterocolitis or gastroschisis (n = 10). The surgical subjects (n = 9) had lower sleep efficiency, lower percentage of active sleep, and more spontaneous arousals compared with the nonsurgical group. CONCLUSIONS: The use of the conformational positioner improved sleep efficiency vs the standard mattress in premature infants with feeding difficulties. Infants requiring surgery or with gastrointestinal diagnoses may be more susceptible to environmental stress.

OBJECTIVE: The aim of this study was to evaluate fetal lung growth rate for isolated left-sided congenital diaphragmatic hernia (CDH) using serial magnetic resonance imaging (MRI)-based volumetric measures. METHODS: Early and late gestational (22-30 and >30 weeks' gestation) lung volumetry was obtained by fetal MRI in 47 cases of isolated left-sided CDH. At both of these time points, lung volume indices, including total lung volume (TLV), observed to expected TLV (o/e TLV), and percentage of predicted lung volume (PPLV) as well as their change rates (Δ) and relative Δ during gestation were calculated and analyzed in regard to their capacity to predict neonatal survival. RESULTS: TLV, o/e TLV, and PPLV had various changes during gestation. Late TLV, early and late o/e TLV, and late PPLV were predictive of neonatal survival. Non-survivors had lower ΔTLV and more negative relative ΔPPLV than survivors (1.18 vs 1.85 mL/week, P = 0.004 and -4.15%/week vs -1.95%/week, P = 0.002, respectively). CONCLUSIONS: The severity of pulmonary hypoplasia is dynamic and can worsen in the third trimester. MRI lung volumetry repeated in late gestation can provide additional information on individual lung growth that may facilitate prenatal counseling and focus perinatal management.

PURPOSE: Sleep and ongoing cycling of sleep states are required for neurosensory processing, learning, and brain plasticity. Many aspects of neonatal intensive care environments such as handling for routine and invasive procedures, bright lighting, and noise can create stress, disrupt behavior, and interfere with sleep in prematurely born infants. The study empirically investigated whether a 30-minute observation of infant sleep states and behavior could differentiate an intervention to promote sleep in premature infants with feeding difficulties relative to conventional care (standard positioning, standard crib mattress [SP]). We included an intervention to determine the ability of the method to discriminate treatments and generate a benchmark for future improvements. The intervention, a conformational positioner (CP), is contoured around the infant to provide customized containment and boundaries. To more fully verify the 30-minute observational sleep results, standard polysomnography was conducted simultaneously and sleep outcomes for the 2 modalities were compared. SUBJECTS: In a randomized crossover clinical trial, 25 infants, 31.5 ± 0.6 weeks' gestational age and 38.4 ± 0.6 weeks at the study, with gastrointestinal conditions or general feeding difficulties used each intervention during an overnight neonatal intensive care unit sleep study. METHODS: Infant sleep states and behaviors were observed during two 30-minute periods--that is, on the positioner and mattress--using the naturalistic observation of newborn behavior. Two certified developmental care nurses assessed sleep state, self-regulatory, and stress behaviors during 2-minute intervals and summed over 30 minutes. Sleep characteristics from standard polysomnography were measured at the time of behavior observations. RESULTS: Infants on CP spent significantly less time in alert, active awake, or crying states by observation compared with SP. Surgical subjects spent more time awake, active awake, or crying and displayed a higher number of behavior state changes than the nonsurgical infants. The percentage of time in observed deep sleep and quiet sleep was correlated with both percentage sleep efficiency (r = 0.78) and fewer state shifts per hour (r = -0.65) from electroencephalogram (EEG). Sleep efficiency by EEG was greater on CP versus SP. CONCLUSIONS: The CP enabled sleep compared with the standard mattress (SP) over 30-minute observation periods. Sleep status from behavioral observation was verified by standard EEG-based sleep techniques. Behavioral observation of sleep states may be a useful strategy for measuring the effectiveness of strategies to facilitate sleep in premature infants. Surgical subjects may benefit from additional interventions to promote sleep.

OBJECTIVE: To develop a consensus guideline to meet nutritional challenges faced by infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: The CDH Focus Group utilized a modified Delphi method to develop these clinical consensus guidelines (CCG). Topic leaders drafted recommendations after literature review and group discussion. Each recommendation was sent to focus group members via a REDCap survey tool, and members scored on a Likert scale of 0-100. A score of > 85 with no more than 25% outliers was designated a priori as demonstrating consensus among the group. RESULTS: In the first survey 24/25 recommendations received a median score > 90 and after discussion and second round of surveys all 25 recommendations received a median score of 100. CONCLUSIONS: We present a consensus evidence-based framework for managing parenteral and enteral nutrition, somatic growth, gastroesophageal reflux disease, chylothorax, and long-term follow-up of infants with CDH.

BACKGROUND: Nosocomial [hospital-associated or neonatal intensive care unit (NICU)-associated] infections occur in as many as 10 to 36% of very low-birth-weight infants cared for in NICUs. OBJECTIVE: To determine the potentially avoidable, incremental costs of care associated with NICU-associated bloodstream infections. STUDY DESIGN: This retrospective study included all NICU admissions of infants weighing 401 to 1500 g at birth in the greater Cincinnati region from January 1, 2005, through December 31, 2007. Nonphysician costs of care were compared between infants who developed at least one bacterial bloodstream infection prior to NICU discharge or death and infants who did not. Costs were adjusted for clinical and demographic characteristics that are present in the first 3 days of life and are known associates of infection. RESULTS: Among 900 study infants with no congenital anomaly and no major surgery, 82 (9.1%) developed at least one bacterial bloodstream infection. On average, the cost of NICU care was $16,800 greater per infant who experienced NICU-associated bloodstream infection. CONCLUSION: Potentially avoidable costs of care associated with bloodstream infection can be used to justify investments in the reliable implementation of evidence-based interventions designed to prevent these infections.

Current literature for congenital diaphragmatic hernia (CDH) focuses on the comparison of the overall mortality in CDH patients. Only a few studies concentrate on analyzing the unstable patients who could not achieve surgical repair, as well as those who could but did not survive after. Hence, this study aimed to analyze the effects of various parameters on the timing of death. A retrospective analysis was performed by using the data of all CDH patients from 2003 to 2016 at a single tertiary center. Patients who were diagnosed with left-sided CDH and expired were included in the study regardless of the cause. Of the 66 expired patients, 5 were excluded due to right-sided CDH. The study population constituted a total of 61 patients, of which 31 patients expired prior to CDH repair, and 30 patients expired at different times after CDH repair. Multinomial regression analysis identified that the ECMO need (B = 20.257, p = 0.000, OR: 62.756, 95% CI 10.600-371.384) and O/E LHR (B = 20.376, p = 0.000, OR: 70.663, 95% CI 48.716-102.415) values were the independent predictors that influenced mortality in this cohort. Prenatal pulmonary measurements are the major predictors determining the severity of the disease in patients with CDH.
RESUMEN
OBJECTIVE: Compare in-hospital outcomes in gastroschisis with intestinal atresia versus simple gastroschisis (GS) using a national database. STUDY DESIGN: The Children's Hospitals Neonatal Database identified infants with gastroschisis from 2010 to 2016. RESULTS: 2078 patients with gastroschisis were included: 183 (8.8%) with co-existing intestinal atresia, 1713 (82.4%) with simple gastroschisis, the remainder with complex gastroschisis without atresia. Length of hospitalization was longer for those with atresia, and yielded higher rates of mortality, medical NEC, and intestinal perforation. They began enteral feedings later, were less likely to initiate feeds orally, and reached full feedings later. They were less likely to be receiving any maternal breast milk or breastfeeding at discharge and more likely than simple gastroschisis to be discharged with a feeding tube. CONCLUSION: A large multicenter cohort showed gastroschisis with atresia results in worse outcomes and complications, including necrotizing enterocolitis, feeding delays, and enteral feeding tube dependence.

OBJECTIVE: Early onset infection (EOI) in gastroschisis is rare. Excess antibiotic exposure in neonates increases necrotizing enterocolitis and mortality. We evaluated antibiotic exposure and EOI in gastroschisis. STUDY DESIGN: Retrospective cohort analysis between 2010-2016 in the Children's Hospital Neonatal Database. Included: Infants ≥32 weeks with gastroschisis admitted <48 h. Excluded: major anomalies or surgical intervention prior to admission. PRIMARY OUTCOME: EOI diagnosis (<72 h). RESULTS: In 2021 patients with gastroschisis, median gestational age was 36 weeks (IQR 35, 37). 93.9% patients received empiric antibiotics after delivery, with median 7 days duration (IQR 3, 9). Only 13 patients (0.64%) had early positive blood culture. The rate of late onset blood stream infection (7.08%) was higher, and higher in complex (18%) than simple gastroschisis (4.8%, p < 0.001). CONCLUSION: Despite low incidence of EOI and risks of excess antibiotic exposure, neonates with gastroschisis are exposed to long courses of empiric antibiotics. These data should stimulate interinstitution work to improve antibiotic prescribing.

OBJECTIVE: To predict pulmonary hypertension (PH) therapy at discharge in a large multicenter cohort of infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: Six-year linked records from Children's Hospitals Neonatal Database and Pediatric Health Information System were used; patients whose diaphragmatic hernia was repaired before admission or referral, who were previously home before admission or referral, and non-survivors were excluded. The primary outcome was the use of PH medications at discharge and the secondary outcome was an inter-center variation of therapies during inpatient utilization. Clinical factors were used to develop a multivariable equation randomly applied to 80% cohort; validated in the remaining 20% infants. RESULTS: A total of 831 infants with CDH from 23 centers were analyzed. Overall, 11.6% of survivors were discharged on PH medication. Center, duration of mechanical ventilation, and duration of inhaled nitric oxide were associated with the use of PH medication at discharge. This model performed well in the validation cohort area under the receiver operating characteristic curve of 0.9, goodness-of-fit χ2, p = 0.17. CONCLUSIONS: Clinical variables can predict the need for long-term PH medication after NICU hospitalization in surviving infants with CDH. This information may be useful to educate families and guide the development of clinical guidelines.

OBJECTIVE: To compare three bronchopulmonary dysplasia (BPD) definitions against hospital outcomes in a referral-based population. STUDY DESIGN: Data from the Children's Hospitals Neonatal Consortium were classified by 2018 NICHD, 2019 NRN, and Canadian Neonatal Network (CNN) BPD definitions. Multivariable models evaluated the associations between BPD severity and death, tracheostomy, or length of stay, relative to No BPD references. RESULTS: Mortality was highest in 2019 NRN Grade 3 infants (aOR 225), followed by 2018 NICHD Grade 3 (aOR 145). Infants with lower BPD grades rarely died (<1%), but Grade 2 infants had aOR 7-21-fold higher for death and 23-56-fold higher for tracheostomy. CONCLUSIONS: Definitions with 3 BPD grades had better discrimination and Grade 3 2019 NRN had the strongest association with outcomes. No/Grade 1 infants rarely had severe outcomes, but Grade 2 infants were at risk. These data may be useful for counseling families and determining therapies for infants with BPD.

It is estimated that about two thirds of newborns will appear clinically jaundiced during their first weeks of life. As newborns and their mothers spend fewer days in the hospital after birth, the number of infants readmitted yearly in the United States for neonatal jaundice over the last 10 years has increased by 160%. A portion of these infants present to the emergency department, requiring a careful history and physical examination assessing them for the risk factors associated with pathologic bilirubin levels. Although the spectrum of illness may be great, the overwhelming etiology of neonatal jaundice presenting to an emergency department is physiologic and not due to infection or isoimmunization. Therefore, a little more than a good history, physical examination, and indirect/direct bilirubin levels are needed to evaluate an otherwise well-appearing jaundiced newborn. The American Academy of Pediatrics' 2004 clinical practice guidelines for "Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation" are a helpful and easily accessible resource when evaluating jaundiced newborns (available at http://aappolicy.aappublications.org/cgi/content/full/pediatrics;114/1/297). There are several exciting developments on the horizon for the diagnosis and management of hyperbilirubinemia including increasing use of transcutaneous bilirubin measuring devices and medications such as tin mesoporphyrin and intravenous immunoglobulin that may decrease the need for exchange transfusions.

BACKGROUND: The decision to pursue chronic mechanical ventilation involves a complex mix of clinical and social considerations. Understanding the medical indications to pursue tracheostomy would reduce the ambiguity for both providers and families and facilitate focus on appropriate clinical goals. OBJECTIVE: To describe potential indications to pursue tracheostomy and chronic mechanical ventilation in infants with severe BPD (sBPD). STUDY DESIGN: We surveyed centers participating in the Children's Hospitals Neonatal Consortium to describe their approach to proceed with tracheostomy in infants with sBPD. We requested a single representative response per institution. Question types were fixed form and free text responses. RESULTS: The response rate was high (31/34, 91%). Tracheostomy was strongly considered when: airway malacia was present, PCO2 ≥ 76-85 mmHg, FiO2 ≥ 0.60, PEEP ≥ 9-11 cm H2O, respiratory rate ≥ 61-70 breaths/min, PMA ≥ 44 weeks, and weight <10th %ile at 44 weeks PMA. CONCLUSIONS: Understanding the range of indications utilized by high level NICUs around the country to pursue a tracheostomy in an infant with sBPD is one step toward standardizing consensus indications for tracheostomy in the future.
