Using buprenorphine to treat neonatal abstinence syndrome: a quality improvement study.

OBJECTIVE: To assess if treating neonatal abstinence syndrome (NAS) with sublingual buprenorphine (SLB) would decrease the mean duration of therapy (DOT) and length of birth hospital stay (LOS). STUDY DESIGN: Conducted at a tertiary hospital with >6000 annual deliveries and a 2% incidence of NAS, a quality improvement study using plan-do-study-act (PDSA) cycles were utilized. Outcomes were measured using statistical process control (SPC) charts. RESULTS: All NAS patients were treated with SLB, no adverse reactions were reported and the need for an adjunctive agent was static. SPC charts demonstrated decreased variability and special cause variation indicating a reduction in both DOT (from 14.5 to 8.5 days) and LOS (from 18.5 to 13 days).

Early postnatal weight gain, intellectual performance, and body mass index at 7 years of age in term infants with intrauterine growth restriction.

OBJECTIVE: To determine whether the postnatal growth rate of infants with intrauterine growth restriction (IUGR) is associated with later cognitive function and body mass index (BMI). STUDY DESIGN: Infants with IUGR (<2211 g at > or =37 weeks' gestation) were identified in data from the Collaborative Perinatal Project, excluding those with diagnoses affecting cognition or growth. Wechsler Scale of Children's Intelligence (WISC) scores at age 7 years and data on postnatal growth at 16 weeks were available for 463 infants with IUGR. Linear regression relating postnatal growth and WISC score, adjusting for potential confounders, was performed for these infants. BMI at 7 years also was examined. RESULTS: Weight gain at 16 postnatal weeks ranged from 1059 to 5119 g in the infants with IUGR, with lower achieved cognitive testing scores apparent at both extremes (ie, an inverted J-shape; P < .001). Infants gaining 1200 and 5000 g scored 15.5 and 2.4 fewer points, respectively, on the full scale compared with infants with score-maximizing growth. In contrast, BMI at 7 years was linearly related to postnatal weight gain (P < .001). CONCLUSIONS: Growth in the first 4 postnatal months is an independent risk factor for cognitive outcome at age 7 years, with both extremes associated with negative effects.

Implementation of critical congenital heart disease screening in Minnesota.

OBJECTIVE: To assess the level of preparedness and resources needed in Minnesota for the implementation of newborn screening for critical congenital heart diseases (CCHDs). METHODS: A cross sectional survey of all birth centers in Minnesota was performed to assess the capacity to deliver care essential for the CCHD screening program. Compliance with the screening algorithm, nursing workload, and cost were assessed by using a pilot program implemented in 6 normal newborn nurseries. RESULTS: Ninety-one of 99 eligible centers participated in the survey and 90 reported the ability to screen newborns in accordance with recommendations. Only 22 centers, with 63% of births, had access to echocardiography and routinely stocked prostaglandins for neonatal use. Our pilot study screened 7549 newborns with 6 failed screens and 1 CCHD diagnosis. Two of the failed screens were due to misinterpretation of the algorithm, 1 failed screen was not reported, and 4 failed screens were not recognized. Repeated screens were required for 115 newborns, with 29% of retesting due to misinterpretation of the algorithm. The mean nursing time required was 5.5 minutes, and the cost was $5.10 per screen. CONCLUSIONS: In Minnesota, two-thirds of newborns are born in centers with resources for initial diagnosis and management of CCHD. Implementation of a pilot screening program demonstrated minimal increase in nursing workload, but identified problems with interpretation of the algorithm and data reporting. This pilot project suggests the need for simplification of the algorithm, additional training of health care providers, and development of a centralized reporting mechanism.

Nutritional practices in the neonatal intensive care unit: analysis of a 2006 neonatal nutrition survey.

OBJECTIVE: The goal of this investigation was to determine how current parenteral nutrition and enteral nutrition practice intentions for preterm infants compare with published recommendations and previous feeding practices. METHODS: A survey of feeding strategies for 3 preterm infant weight groups was sent to NICU directors, neonatal fellowship directors, neonatologists, neonatal nurse practitioners, and neonatal dieticians. A total of 775 surveys were distributed by both electronic and standard mail services. RESULTS: There were 176 survey responses (23%). The majority of practitioners initiated parenteral nutrition for very preterm infants in the first day of life. Ninety-one percent of respondents increased protein delivery daily. Most respondents increased lipid delivery at a fixed rate, rather than on the basis of triglyceride levels. Insulin was used in 98% of units, but only 12% of the time as a nutritional adjuvant to increase weight gain. Across all birth weight categories, breast milk was prescribed most commonly for the first enteral feeding. Enteral feedings were started earlier and increased faster than in the past, especially for extremely low birth weight infants (<1000 g). The majority of respondents prescribed enteral feedings for infants with indwelling umbilical arterial (75%) and umbilical venous (93%) catheters. Despite data that more rapid feeding advancement is safe, >80% of respondents increased feedings at rates of 10 to 20 mL/kg per day across all weight categories. CONCLUSIONS: Clinicians reported that they are initiating parenteral and enteral nutrition earlier and in larger volumes than in the past, reflecting increased knowledge about best nutritional practices in very preterm neonates. The data suggest that the persistent extrauterine growth failure of preterm infants is not attributable to a lack of best nutritional practice knowledge and intention.
