Variation in Neonate Swaddling Techniques.

BACKGROUND: It is common practice for healthcare practitioners to swaddle infants in newborn nursery and neonatal intensive care unit settings. Despite the widespread use of this practice, the American Academy of Pediatrics neither bans nor recommends swaddling. To date, there has been no standard protocol developed for either healthcare professionals or parents to establish optimal swaddling techniques in terms of infant arm positioning, infant leg positioning, and tightness of wrap. PURPOSE: To evaluate the variability in swaddling techniques used for infants in the newborn nursery and neonatal intensive care unit. METHODS: Across 2 pediatric hospitals, the swaddling positioning of each open-crib infant in the newborn nursery and neonatal intensive care unit was examined. For each infant, the following data were collected: gender, left and right arm position, left and right leg position, and tightness of wrap. RESULTS: In total, 132 swaddle observations were recorded. There was significant variability in swaddling positioning of arms and legs. The most common combination of arm/leg positioning was "mixed arm positioning" and "both legs flexed" (25.0% of all observations). In 9.1% of cases, tightness of wrap around chest was "tight," and in 30.3% of cases, tightness of wrap around legs was "tight." IMPLICATIONS FOR PRACTICE: There was a large variability in swaddling positioning of both arms and legs. For such a widespread practice, the lack of medical guidelines results in inconsistent, and potentially harmful, positioning. Parents and healthcare professionals would benefit from specific, research-driven guidelines regarding proper swaddling techniques. IMPLICATIONS FOR RESEARCH: Different variations on swaddling should be evaluated for consideration of best practice swaddling.

Parental Perception of Risk Associated With Their Premature Infant.

BACKGROUND: Preterm birth has been linked to increased parental stress, depression, and anxiety. Although the rate of neonatal morbidity and mortality decreases with increasing gestational age, recent research has revealed that there is no threshold age for risk or parental concern. PURPOSE: This study examines parental concern about medical and developmental outcomes of their premature infant. METHODS: Parents of 60 premature infants were surveyed in a follow-up clinic regarding their level of concern about 11 morbidities and their child's gestation-adjusted age; these were compared with the infant's inpatient chart. "Concern scores" were tallied and compared across gestational age groups and knowledge of gestation-adjusted age using Chi-square tests of independence. FINDINGS: Many parents reported concerns about morbidities that were unsupported by their child's diagnoses. Across parents of extremely, very, and moderate-late preterm children, the mean concern scores were 13.9, 15.7, and 19.7, respectively. Overall, 62% of parents incorrectly reported the gestation-adjusted age of their child. Parents who were correct were significantly more likely to correctly anticipate abnormal developmental patterns (70%) and growth patterns (65%) than those who were incorrect (33% and 31%, respectively). IMPLICATIONS FOR RESEARCH: Future research should focus on whether NICU graduate parental stress levels are directly linked to the severity of their child's condition, and how physicians can help decrease NICU graduate parental stress. IMPLICATIONS FOR PRACTICE: Parental anxiety regarding all gestational age neonatal intensive care unit infant outcomes can be decreased by a thorough explanation of gestation-adjusted age and a discussion of expected prematurity-related issues.

Newborn screening for Duchenne muscular dystrophy: A two-year pilot study.

OBJECTIVE: Duchenne muscular dystrophy (DMD) is an X-linked disorder resulting in progressive muscle weakness and atrophy, cardiomyopathy, and in late stages, cardiorespiratory impairment, and death. As treatments for DMD have expanded, a DMD newborn screening (NBS) pilot study was conducted in New York State to evaluate the feasibility and benefit of NBS for DMD and to provide an early pre-symptomatic diagnosis. METHODS: At participating hospitals, newborns were recruited to the pilot study, and consent was obtained to screen the newborn for DMD. The first-tier screen measured creatine kinase-MM (CK-MM) in dried blood spot specimens submitted for routine NBS. Newborns with elevated CK-MM were referred for genetic counseling and genetic testing. The latter included deletion/duplication analysis and next-generation sequencing (NGS) of the DMD gene followed by NGS for a panel of neuromuscular conditions if no pathogenic variants were detected in the DMD gene. RESULTS: In the two-year pilot study, 36,781 newborns were screened with CK-MM. Forty-two newborns (25 male and 17 female) were screen positive and referred for genetic testing. Deletions or duplications in the DMD gene were detected in four male infants consistent with DMD or Becker muscular dystrophy. One female DMD carrier was identified. INTERPRETATION: This study demonstrated that the state NBS program infrastructure and screening technologies we used are feasible to perform NBS for DMD. With an increasing number of treatment options, the clinical utility of early identification for affected newborns and their families lends support for NBS for this severe disease.

A Quality Improvement Project to Standardize Surfactant Delivery in the Era of Noninvasive Ventilation.

INTRODUCTION: Continuous positive airway pressure (CPAP) and surfactant both improve outcomes for premature infants with respiratory distress syndrome. However, prolonged trials of CPAP, as well as observation periods after intubation, may delay the administration of surfactant. Late surfactant treatment likely increases the incidence of bronchopulmonary dysplasia, which leads to significant morbidity and healthcare utilization. METHODS: We aimed to decrease time from meeting standard criteria (start of a continuous run of FiO2 > 40% or PaCO2 > 65 for >90 min) to intubation, and from intubation to surfactant administration, for infants <1,500 g or younger than 32 weeks gestation. Retrospective data collection from the electronic medical record assessed those process measures as the primary endpoints. Balancing measures were the adverse outcomes of asymmetric lung disease, the inappropriate position of the endotracheal tube, or pneumothorax on the first x-ray (within 24 h) after surfactant. RESULTS: Mean time to intubation for infants 28-32 weeks gestation decreased from 321 to 81 minutes in response to a literature review for physicians and free-text orders for notification. Time to intubation for infants younger than 28 weeks gestation did not change. Administration of surfactant within 1 hour of intubation improved from 78% to 100% after a program for trainees and coordination with radiology. There were no adverse occurrences. CONCLUSIONS: Educational interventions and targeted process change can successfully implement standard criteria for intubation and surfactant administration for premature infants. Determination of an acceptable range of evidence-based practice is essential for the engagement of medical staff. Timely intubation and surfactant may decrease bronchopulmonary dysplasia.

Prevalence and Longevity of PTSD Symptoms Among Parents of NICU Infants Analyzed Across Gestational Age Categories.

Objective. This study aims to investigate whether posttraumatic stress disorder (PTSD) symptoms exist >1 year after neonatal intensive care unit (NICU) experience and whether PTSD symptomatology differs across parents of infants of different gestational age categories. Methods. A survey was given to parents at routine NICU follow-up visits. Parents completed the PTSD CheckList-Civilian (PCL-C), a standardized scale comprising 17 key symptoms of PTSD. Parents also rated how traumatic their birth experience, first day in the NICU, and first week in the NICU were from "Not Traumatic at All" to "Most Traumatic." Fisher's exact test was used to compare PCL-C responses across gestational age categories (Extremely Preterm, Very Preterm, Moderate to Late preterm, and Full Term). Results. Eighty parents participated. In total, 15% of parents had "Moderate to High Severity" PTSD symptoms. There were no statistical differences in PTSD prevalence between parents of children <1 year old and parents of children >1 year old (P = .51). There was also no statistical difference in prevalence of "Moderate to High Severity" level of PTSD symptoms across gestational age (P = .16). Overall, 38% of parents rated at least one experience as "Most traumatic." Conclusion. A high percentage of parents who had a recent NICU experience and parents who had a NICU experience more than a year ago demonstrated PTSD symptoms. In light of these results, many parents of NICU graduates-both mothers and fathers-would benefit from access to long-term counseling services.

Acquired oral commissure defect: a complication of prolonged endotracheal intubation.

A number of complications during and following endotracheal intubation of infants are well described in the literature. We describe a rare case of an oral commissure defect acquired from prolonged endotracheal intubation in a ventilator-dependent preterm infant.

Newborn brain infarction: clinical aspects and magnetic resonance imaging.

OBJECTIVE: We describe the clinical and imaging studies of 11 full-term babies with neonatal stroke. We classify the neonatal non-hemorrhagic strokes as thrombotic, embolic, or global vascular insufficiency and determine if this classification is improved by adding magnetic resonance spectroscopy (MRS) and diffusion-weighted imaging (DWI) to conventional magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA). METHODS: Clinically, eight of the 11 babies presented with seizures, one with apnea, and two with lethargy. Conventional MRI and DWI were used to classify each infarct as being either borderzone or vascular distribution. The location of infarction revealed the presumed vascular pathophysiology. RESULTS: Infants were classified as having either embolic (bilateral middle cerebral artery,n=1), global ischemic (bilateral borderzone, n=2), or thrombotic infarction (unilateral middle cerebral artery, n=7; bilateral posterior cerebral arteries, n=1). DWI and MRS detected a small infarct better than conventional MRI in one patient. MRA showed abnormal intracranial arteries in three, all of who were in the thrombotic group. Even though MRS was more sensitive than conventional MRI in detecting ischemia/infarction in one patient, in another there was no detectable lactate in the stroke region found on conventional MRI. Clinical presentation was similar in global ischemia and focal infarctions, but newborn stroke was more likely to present with lateralizing focal motor seizures. Seizures were the most common presenting sign, with a paucity of other focal neurological deficits. CONCLUSION: MRI is the best approach to determine stroke pathophysiology. Brain infarction frequently presents with seizures. We speculate that the location and distribution of infarction might determine stroke timing, pathophysiology and outcome. Ongoing clinical studies will likely clarify this speculation.

Neonatal outcome of infants born at 500 to 800 grams from 1990 through 1998 in a tertiary care center.

OBJECTIVE: To assess if there have been changes in survival, demographic data, obstetric features, neonatal morbidity, and short-term neurologic/radiographic/neurosensory outcome of 500- to 800-g infants born in a tertiary care neonatal center from 1990 through 1998. STUDY DESIGN: Records of all 500- to 800-g infants born at North Shore University Hospital during 1990-1998 were reviewed to determine demographic data, survival by weight and gestational age (GA), obstetric features, neonatal morbidity, and short-term neurologic/radiographic/neurosensory outcome. Newborn infants were grouped into three triennia: 1990-1992, 1993-1995, and 1996-1998 and compared across time. RESULTS: Of the 173 infants admitted to the neonatal intensive care unit, 112 survived. Improved survival was documented: 40% in 1990-1992, 73% in 1993-1995, and 81% in 1996-1998 (p < 0.0001). Improved survival was also noted in each of the three weight cohorts, as well as in infants < or =26 weeks GA. An increased use of antenatal corticosteroids and increased number of deliveries by cesarean section (C/S) were noted across time. The incidence of 0 to 3 Apgar scores at both 1 and 5 minutes decreased across time. Necrotizing enterocolitis in survivors and expected short-term neurologic/radiographic/neurosensory outcome improved between 1990-1992 and 1996-1998, with a trend toward reduced IVH grade III to IV. The incidence of other neonatal morbidities did not change throughout the time period. CONCLUSIONS: The data document that survival rates continued to improve for 500- to 800-g infants throughout the 1990s. This was concurrent with an increase in "low-risk, expected normal" infants, increased number of deliveries by C/S, decreased incidence of low Apgar scores at both 1 and 5 minutes, and an increased use of antenatal corticosteroids.

Parental perception of premature infant growth and feeding behaviors: use of gestation-adjusted age and assessing for developmental readiness during solid food introduction.

BACKGROUND: The extent to which pediatricians inform parents about gestation-adjusted age growth plotting is unclear. Uninformed parents may have decreased satisfaction of infant growth. Subsequent early introduction of solid foods may lead to avoidant feeding behaviors and poor parental perception of infant feeding patterns. METHODS: Questionnaires regarding infant growth and feeding behaviors were given to parents (n = 76) of premature infants. The Wilcoxon rank-sum and χ(2)/Fisher's exact tests were used. RESULTS: Uninformed parents were less satisfied with their infant's growth (P < .002). Uninformed parents had more developmentally unready infants at the time of solid food introduction compared with informed parents (P = .03). Significant differences were found in avoidant feeding behaviors and parental perception of infant feeding patterns between developmentally ready and unready infants. CONCLUSION: Pediatricians should adjust for gestational age when plotting growth and assess for developmental readiness for premature infants when recommending solid foods.
