A multicenter matched-cohort analysis of gastroschisis outcomes in infants born before 32 weeks gestation

OBJECTIVE

To examine neonatal outcomes of infants with gastroschisis born <32 weeks' gestation compared to matched infants without gastroschisis.

STUDY DESIGN

Retrospective matched-cohort analysis of infants with gastroschisis born <32 weeks' gestation at Children's Hospitals Neonatal Consortium (CHNC) NICUs from 2010 to 2022 compared to gestational age-matched controls.

RESULTS

The study included 119 infants with gastroschisis and 357 matched infants; 60% of infants born 29-32 weeks, 23% born 26-28 weeks, and 16% born < 25 weeks. Mortality was not significantly different between groups (11% vs. 9%, p = 0.59). Preterm co-morbidities such as IVH, BPD, ROP, and PVL were similar, as were rates of surgical NEC. Infants with gastroschisis had longer hospital stays (92 vs. 67 days), higher CLABSI and UTIs, and were more likely to need feeding support at discharge.

CONCLUSION

Compared to infants without gastroschisis, infants <32 weeks' gestation with gastroschisis had similar risks for inpatient mortality, NEC, and other preterm co-morbidities.

Current Practices for Genetic Testing in Neonatal Extracorporeal Membrane Oxygenation: Findings from a National survey

Introduction: Comprehensive genetic testing with whole-exome (WES) or whole-genome (WGS) sequencing facilitates diagnosis, can optimize treatment, and may improve outcomes in critically ill neonates, including those requiring extracorporeal membrane oxygenation (ECMO) for respiratory failure. Our objective was to describe practice variation and barriers to the utilization of comprehensive genetic testing for neonates on ECMO.Methods: We performed a cross-sectional survey of Level IV neonatal intensive care units in the United States across the Children's Hospitals Neonatal Consortium (CHNC).Results: Common indications for WES and WGS included concerning phenotype, severity of disease, unexpected postnatal clinical course, and inability to wean from ECMO support. Unexpected severity of disease on ECMO was the most common indication for rapid genetic testing. Cost of utilization was the primary barrier to testing. If rapid WES or WGS were readily available, 63% of centers would consider incorporating universal screening for neonates upon ECMO cannulation.Conclusion: Despite variation in the use of WES and WGS, universal testing may offer earlier diagnosis and influence the treatment course among neonates on ECMO. Cost is the primary barrier to utilization and most centers would consider incorporating universal screening on ECMO if readily available.

Development of an Approach to Assessing Pediatric Fellows' Transport Medical Control Skills

BACKGROUND AND OBJECTIVE

Pediatric interfacility transport teams facilitate access to subspecialty care, and physicians often guide management remotely as transport medical control (TMC). Pediatric subspecialty fellows frequently perform TMC duties, but tools assessing competency are lacking. Our objective was to develop content validity for the items required to assess pediatric subspecialty fellows' TMC skills.

METHODS

We conducted a modified Delphi process among transport and fellow education experts in pediatric critical care medicine, pediatric emergency medicine, neonatal-perinatal medicine, and pediatric hospital medicine. The study team generated an initial list of items on the basis of a literature review and personal experience. A modified Delphi panel of transport experts was recruited to participate in 3 rounds of anonymous, online voting on the importance of the items using a 3-point Likert scale (marginal, important, essential). We defined consensus for inclusion as ≥80% agreement that an item was important/essential and consensus for exclusion as ≥80% agreement that an item was marginal.

RESULTS

The study team of 20 faculty drafted an initial list of items. Ten additional experts in each subspecialty served on the modified Delphi panel. Thirty-six items met the criteria for inclusion, with widespread agreement across subspecialties. Only 1 item, "discussed bed availability," met the criteria for inclusion among some subspecialties but not others. The study team consolidated the final list into 26 items for ease of use.

CONCLUSIONS

Through a consensus-based process among transport experts, we generated content validity for the items required to assess pediatric subspecialty fellows' TMC skills.

Gastroschisis and low incidence of early-onset infection: a case for antimicrobial stewardship

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.

Gastroschisis with intestinal atresia leads to longer hospitalization and poor feeding outcomes

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.

A Fetal Presentation of a Ruptured Right Ventricular Diverticulum

Ruptured diverticula and ventricular aneurysms are rare in the fetus, with a limited number of case reports published previously. Additional fetal complications secondary to these ventricular wall abnormalities can be seen. Interventional measures can be considered and attempted either in utero or postnatally to improve the chance of survival. We present a case of a ruptured diverticulum in a fetus and the clinical course.

Inhaled epoprostenol therapy for pulmonary hypertension: Improves oxygenation index more consistently in neonates than in older children

The purpose of this study was to determine the efficacy of inhaled epoprostenol for treatment of acute pulmonary hypertension (PH) in pediatric patients and to formulate a plan for a prospective, randomized study of pulmonary vasodilator therapy in this population. Inhaled epoprostenol is an effective treatment for pediatric PH. A retrospective chart review was conducted of all pediatric patients who received inhaled epoprostenol at a tertiary care hospital between October 2005 and August 2007. The study population was restricted to all patients under 18 years of age who received inhaled epoprostenol for greater than 1 hour and had available data for oxygenation index (OI) calculation. Arterial blood gas values and ventilator settings were collected immediately prior to epoprostenol initiation, and during epoprostenol therapy (as close to 12 hours after initiation as possible). Echocardiograms were reviewed during two time frames: Within 48 hours prior to therapy initiation and within 96 hours after initiation. Of the 20 patients in the study population, 13 were neonates, and the mean OI for these patients improved during epoprostenol administration (mean OI before and during therapy was 25.6±16.3 and 14.5±13.6, respectively, P=0.02). Mean OI for the seven patients greater than 30 days of age was not significantly different during treatment (mean OI before and during therapy was 29.6±15.0 and 25.6±17.8, P=0.56). Improvement in echocardiographic findings (evidence of decreased right-sided pressures or improved right ventricular function) was demonstrated in 20% of all patients. Inhaled epoprostenol is an effective therapy for the treatment of selected pediatric patients with acute PH. Neonates may benefit more consistently from this therapy than older infants and children. A randomized controlled trial is needed to discern the optimal role for inhaled prostanoids in the treatment of acute PH in childhood.

Prenatal consultation with a neonatologist for congenital anomalies: parental perceptions

OBJECTIVES

To investigate parental expectations of a prenatal consultation with a neonatologist for a prenatally diagnosed congenital anomaly, to identify parents' values and unmet needs, and to obtain recommendations for improving physician-parent communication in a prenatal consultation.

METHODS

Parents referred to neonatology for prenatal consultation after the diagnosis of a congenital anomaly. Completed 2 qualitative interviews: the first within 1 week of the consultation and the second 1 week after delivery. Interviews were analyzed for themes by using the constant comparative method associated with the grounded theory method.

RESULTS

Thematic saturation was achieved after 42 interviews (22 women); only mothers participated. Five main themes emerged: (1) preparation; (2) knowledgeable physician; (3) caring providers; (4) allowing hope; and (5) time. Mothers believed that a consultation with a neonatologist helped them prepare for the perinatal course. They wished to know the management plan and all possible outcomes. Mothers wanted information specific to their situation and tailored to their knowledge base. Receiving conflicting information from physicians increased anxiety and eroded confidence. Seeing the NICU during the consultation was emotionally difficult but valuable. Mothers wanted realistic information, regardless of how grim, yet wanted to retain hope. All mothers would recommend a prenatal consultation with a neonatologist.

CONCLUSIONS

Mothers perceived that a consultation with a neonatologist, which included a NICU tour, prepared them for the perinatal course. Parents want realistic medical information, specific to their situation, provided in an empathetic manner and want to be allowed to hope for the best possible outcome.
