    Medical and surgical interventions and outcomes for infants with trisomy 18 (T18) or trisomy 13 (T13) at children's hospitals neonatal intensive care units (NICUs)
    (Springer Nature, 2021) Acharya, Krishna; Leuthner, Steven R.; Zaniletti, Isabella; Niehaus, Jason Z.; Bishop, Christine E.; Coghill, Carl H.; Datta, Ankur; Dereddy, Narendra; DiGeronimo, Robert; Jackson, Laura; Ling, Con Yee; Matoba, Nana; Natarajan, Girija; Pritha Nayak, Sujir; Brown Schlegel, Amy; Seale, Jamie; Shah, Anita; Weiner, Julie; Williams, Helen O.; Wojcik, Monica H.; Fry, Jessica T.; Sullivan, Kevin; Palliative Care and Ethics Focus Group of the Children’s Hospital Neonatal Consortium (CHNC); Pediatrics, School of Medicine
    Objectives: To examine characteristics and outcomes of T18 and T13 infants receiving intensive surgical and medical treatment compared to those receiving non-intensive treatment in NICUs. Study design: Retrospective cohort of infants in the Children's Hospitals National Consortium (CHNC) from 2010 to 2016 categorized into three groups by treatment received: surgical, intensive medical, or non-intensive. Results: Among 467 infants admitted, 62% received intensive medical treatment; 27% received surgical treatment. The most common surgery was a gastrostomy tube. Survival in infants who received surgeries was 51%; intensive medical treatment was 30%, and non-intensive treatment was 72%. Infants receiving surgeries spent more time in the NICU and were more likely to receive oxygen and feeding support at discharge. Conclusions: Infants with T13 or T18 at CHNC NICUs represent a select group for whom parents may have desired more intensive treatment. Survival to NICU discharge was possible, and surviving infants had a longer hospital stay and needed more discharge supports.

    Ventilation Strategies during Extracorporeal Membrane Oxygenation for Neonatal Respiratory Failure: Current Approaches among Level IV Neonatal ICUs
    (Wolters Kluwer, 2022-11) Ibrahim, John; Mahmood, Burhan; DiGeronimo, Robert; Rintoul, Natalie E.; Hamrick, Shannon E.; Chapman, Rachel; Keene, Sarah; Seabrook, Ruth B.; Billimoria, Zeenia; Rao, Rakesh; Daniel, John; Cleary, John; Sullivan, Kevin; Gray, Brian; Weems, Mark; Dirnberger, Daniel R.; Surgery, School of Medicine
    OBJECTIVES: To describe ventilation strategies used during extracorporeal membrane oxygenation (ECMO) for neonatal respiratory failure among level IV neonatal ICUs (NICUs). DESIGN: Cross-sectional electronic survey. SETTING: Email-based Research Electronic Data Capture survey. PATIENTS: Neonates undergoing ECMO for respiratory failure at level IV NICUs. INTERVENTIONS: A 40-question survey was sent to site sponsors of regional referral neonatal ECMO centers participating in the Children’s Hospitals Neonatal Consortium. Reminder emails were sent at 2- and 4-week intervals. MEASUREMENTS AND MAIN RESULTS: Twenty ECMO centers responded to the survey. Most primarily use venoarterial ECMO (65%); this percentage is higher (90%) for congenital diaphragmatic hernia. Sixty-five percent reported following protocol-based guidelines, with neonatologists primarily responsible for ventilator management (80%). The primary mode of ventilation was pressure control (90%), with synchronized intermittent mechanical ventilation (SIMV) comprising 80%. Common settings included peak inspiratory pressure (PIP) of 16–20 cm H2O (55%), positive end-expiratory pressure (PEEP) of 9–10 cm H2O (40%), I-time 0.5 seconds (55%), rate of 10–15 (60%), and Fio2 22–30% (65%). A minority of sites use high-frequency ventilation (HFV) as the primary mode (5%). During ECMO, 55% of sites target some degree of lung aeration to avoid complete atelectasis. Fifty-five percent discontinue inhaled nitric oxide (iNO) during ECMO, while 60% use iNO when trialing off ECMO. Nonventilator practices to facilitate decannulation include bronchoscopy (50%), exogenous surfactant (25%), and noninhaled pulmonary vasodilators (50%). Common ventilator thresholds for decannulation include PEEP of 6–7 (45%), PIP of 21–25 (55%), and tidal volume 5–5.9 mL/kg (50%). CONCLUSIONS: The majority of level IV NICUs follow internal protocols for ventilator management during neonatal respiratory ECMO, and neonatologists primarily direct management in the NICU. While most centers use pressure-controlled SIMV, there is considerable variability in the range of settings used, with few centers using HFV primarily. Future studies should focus on identifying respiratory management practices that improve outcomes for neonatal ECMO patients.
