Video Abstract: media-1vid110.1542/5839992674001PEDS-VA_2018-1485 BACKGROUND AND OBJECTIVES: Recently, the Neonatal Resuscitation Program (NRP) recommended against routine endotracheal suctioning of meconium-stained nonvigorous newborns but suggested resuscitation with positive pressure ventilation. Our purpose is to study the effects of this change in management. METHODS: In this multicenter cohort study, we compare 130 nonvigorous newborns born during the retrospective 1-year period before the implementation of new NRP guidelines (October 1, 2015, to September 30, 2016) to 101 infants born during the 1-year prospective period after implementation (October 1, 2016, to September 30, 2017). RESULTS: Endotracheal suctioning was performed predominantly in the retrospective group compared with the prospective group (70% vs 2%), indicating the change in practice. A significantly higher proportion of newborns were admitted to the NICU for respiratory issues in the prospective group compared with the retrospective group (40% vs 22%) with an odds ratio (OR) of 2.2 (95% confidence interval [CI]: 1.2-3.9). Similarly, a significantly higher proportion of infants needed oxygen therapy (37% vs 19%) with an OR of 2.5 (95% CI: 1.2-4.5), mechanical ventilation (19% vs 9%) with an OR of 2.6 (95% CI: 1.1-5.8), and surfactant therapy (10% vs 2%) with an OR of 5.8 (95% CI: 1.5-21.8). There were no differences in the incidence of other outcomes, including meconium aspiration syndrome. CONCLUSIONS: The recent NRP guideline change was not associated with an increased incidence of meconium aspiration syndrome but was associated with an increased incidence of NICU admissions for respiratory issues. Also, the need for mechanical ventilation, oxygen, and surfactant therapy increased.

We previously published rates of pediatric stroke using our population-based Greater Cincinnati Northern Kentucky Stroke Study (GCNK) for periods July 1993-June 1994 and 1999. We report population-based rates from 2 additional study periods: 2005 and 2010. We identified all pediatric strokes for residents of the GCNK region that occurred in July 1, 1993-June 30, 1994, and calendar years 1999, 2005, and 2010. Stroke cases were ascertained by screening discharge ICD-9 codes, and verified by a physician. Pediatric stroke was defined as stroke in those <20 years of age. Stroke rates by study period, overall, by age and by race, were calculated. Eleven children died within 30 days, yielding an all-cause case fatality rate of 15.7% (95% confidence interval 1.1%, 26.4%) with 3 (27.3%) ischemic, 6 (54.5%) hemorrhagic, and 2 (18.2%) unknown stroke type. The pediatric stroke rate of 4.4 per 100 000 in the GCNK study region has not changed over 17 years.

OBJECTIVES: Infants with short bowel syndrome (SBS) require diligent nutritional support for adequate growth. Enteral independence is a primary goal, but must be balanced with ensuring sufficient nutrition. We aimed to describe growth trajectory in infants with SBS as function of nutritional intake during first 2 years of life. METHODS: Infants with SBS were reviewed (2008-2016). z Scores for weight, height, and head circumference (HC) were recorded at birth, 3, 6, 12, 18, and 24 months. Nutritional intake, serum liver enzyme, and bilirubin levels were assessed at all time points. Pearson correlation coefficients were used to measure association with P < 0.05 considered significant. RESULTS: Forty-one infants were included, with median gestational age of 34 weeks (interquartile range [IQR] 29-36 weeks). Median small bowel length was 36 cm (IQR 26-52 cm) and median % expected small bowel length was 28% (IQR 20%-42%). Mean z scores for weight and length were >0 at birth, but <0 from 3 months to 2 years. HC remained <0 throughout the study. Mean z scores at 2 years for weight, length, HC, and weight-for-length were -0.90 (SD 1.1), -1.33 (SD 1.4), -0.67 (SD 1.2), and -0.12 (SD 1.2), respectively. Percentage calories from PN was positively correlated with weight in the first 3 months of life (P = 0.01). CONCLUSIONS: Babies with SBS are high risk for poor growth during the first 2 years of life. Although weaning PN is important for these patients, doing so too quickly in infancy may contribute to compromised growth. The long-term impact on overall development is not known.
