Item Incidence, management, and outcomes of cardiovascular insufficiency in critically ill term and late preterm newborn infants(Thieme, 2014-11) Fernandez, Erika; Watterberg, Kristi L.; Faix, Roger G.; Yoder, Bradley A.; Walsh, Michele C.; Backstrom Lacy, Conra; Osborne, Karen A.; Das, Abhik; Kendrick, Douglas E.; Stoll, Barbara J.; Poindexter, Brenda B.; Laptook, Abbot R.; Kennedy, Kathleen A.; Schibler, Kurt; Bell, Edward F.; Van Meurs, Krisa P.; Frantz III, Ivan D.; Goldberg, Ronald N.; Shankaran, Seetha; Carlo, Waldemar A.; Ehrenkranz, Richard A.; Sánchez, Pablo J.; Higgins, Rosemary D.; Department of Pediatrics, IU School of MedicineOBJECTIVE: The objective of this study was to characterize the incidence, management, and short-term outcomes of cardiovascular insufficiency (CVI) in mechanically ventilated newborns, evaluating four separate prespecified definitions. STUDY DESIGN: Multicenter, prospective cohort study of infants ≥34 weeks gestational age (GA) and on mechanical ventilation during the first 72 hours. CVI was prospectively defined as either (1) mean arterial pressure (MAP) < GA; (2) MAP < GA + signs of inadequate perfusion; (3) any therapy for CVI; or (4) inotropic therapy. Short-term outcomes included death, days on ventilation, oxygen, and to full feedings and discharge. RESULTS: Of 647 who met inclusion criteria, 419 (65%) met ≥1 definition of CVI. Of these, 98% received fluid boluses, 36% inotropes, and 17% corticosteroids. Of treated infants, 46% did not have CVI as defined by a MAP < GA ± signs of inadequate perfusion. Inotropic therapy was associated with increased mortality (11.1 vs. 1.3%; p < 0.05). CONCLUSION: More than half of the infants met at least one definition of CVI. However, almost half of the treated infants met none of the definitions. Inotropic therapy was associated with increased mortality. These findings can help guide the design of future studies of CVI in newbornsItem Neurodevelopmental outcome of preterm infants enrolled in myo-inositol randomized controlled trial(Springer Nature, 2021) Adams-Chapman, Ira; Watterberg, Kristi L.; Nolen, Tracy L.; Hirsch, Shawn; Cole, Carol A.; Cotten, C. Michael; Oh, William; Poindexter, Brenda B.; Zaterka-Baxter, Kristin M.; Das, Abhik; Backstrom Lacy, Conra; Scorsone, Ann Marie; Duncan, Andrea F.; DeMauro, Sara B.; Goldstein, Ricki F.; Colaizy, Tarah T.; Wilson-Costello, Deanne E.; Purdy, Isabell B.; Hintz, Susan R.; Heyne, Roy J.; Myers, Gary J.; Fuller, Janell; Merhar, Stephanie; Harmon, Heidi M.; Peralta-Carcelen, Myriam; Kilbride, Howard W.; Maitre, Nathalie L.; Vohr, Betty R.; Natarajan, Girija; Mintz-Hittner, Helen; Quinn, Graham E.; Wallace, David K.; Olson, Richard J.; Orge, Faruk H.; Tsui, Irena; Gaynon, Michael; Hutchinson, Amy K.; He, Yu-Guang; Winter, Timothy W.; Yang, Michael B.; Haider, Kathryn M.; Cogen, Martin S.; Hug, Denise; Bremer, Don L.; Donahue, John P.; Lucas, William R.; Phelps, Dale L.; Higgins, Rosemary D.; Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network; Pediatrics, School of MedicineObjective: This study evaluates the 24-month follow-up for the NICHD Neonatal Research Network (NRN) Inositol for Retinopathy Trial. Study design: Bayley Scales of Infants Development-III and a standardized neurosensory examination were performed in infants enrolled in the main trial. Moderate/severe NDI was defined as BSID-III Cognitive or Motor composite score <85, moderate or severe cerebral palsy, blindness, or hearing loss that prevents communication despite amplification were assessed. Results: Primary outcome was determined for 605/638 (95%). The mean gestational age was 25.8 ± 1.3 weeks and mean birthweight was 805 ± 192 g. Treatment group did not affect the risk for the composite outcome of death or survival with moderate/severe NDI (60% vs 56%, p = 0.40). Conclusions: Treatment group did not affect the risk of death or survival with moderate/severe NDI. Despite early termination, this study represents the largest RCT of extremely preterm infants treated with myo-inositol with neurodevelopmental outcome data.
