Endotracheal Tube Size Adjustments Within Seven Days of Neonatal Intubation.

BACKGROUND AND OBJECTIVES: Neonatal endotracheal tube (ETT) size recommendations are based on limited evidence. We sought to determine data-driven weight-based ETT sizes for infants undergoing tracheal intubation and to compare these with Neonatal Resuscitation Program (NRP) recommendations. METHODS: Retrospective multicenter cohort study from an international airway registry. We evaluated ETT size changes (downsizing to a smaller ETT during the procedure or upsizing to a larger ETT within 7 days) and risk of procedural adverse outcomes associated with first-attempt ETT size selection when stratifying the cohort into 200 g subgroups. RESULTS: Of 7293 intubations assessed, the initial ETT was downsized in 5.0% of encounters and upsized within 7 days in 1.5%. ETT downsizing was most common when NRP-recommended sizes were attempted in the following weight subgroups: 1000 to 1199 g with a 3.0 mm (12.6%) and 2000 to 2199 g with a 3.5 mm (17.1%). For infants in these 2 weight subgroups, selection of ETTs 0.5 mm smaller than NRP recommendations was independently associated with lower odds of adverse outcomes compared with NRP-recommended sizes. Among infants weighing 1000 to 1199 g: any tracheal intubation associated event, 20.8% with 2.5 mm versus 21.9% with 3.0 mm (adjusted OR [aOR] 0.62, 95% confidence interval [CI] 0.41-0.94); severe oxygen desaturation, 35.2% with 2.5 mm vs 52.9% with 3.0 mm (aOR 0.53, 95% CI 0.38-0.75). Among infants weighing 2000 to 2199 g: severe oxygen desaturation, 41% with 3.0 mm versus 56% with 3.5mm (aOR 0.55, 95% CI 0.34-0.89). CONCLUSIONS: For infants weighing 1000 to 1199 g and 2000 to 2199 g, the recommended ETT size was frequently downsized during the procedure, whereas 0.5 mm smaller ETT sizes were associated with fewer adverse events and were rarely upsized.

Protocol for a randomized controlled trial to evaluate a year-long (NICU-to-home) evidence-based, high dose physical therapy intervention in infants at risk of neuromotor delay.

INTRODUCTION: Developmental disabilities and neuromotor delay adversely affect long-term neuromuscular function and quality of life. Current evidence suggests that early therapeutic intervention reduces the severity of motor delay by harnessing neuroplastic potential during infancy. To date, most early therapeutic intervention trials are of limited duration and do not begin soon after birth and thus do not take full advantage of early neuroplasticity. The Corbett Ryan-Northwestern-Shirley Ryan AbilityLab-Lurie Children's Infant Early Detection, Intervention and Prevention Project (Project Corbett Ryan) is a multi-site longitudinal randomized controlled trial to evaluate the efficacy of an evidence-based physical therapy intervention initiated in the neonatal intensive care unit (NICU) and continuing to 12 months of age (corrected when applicable). The study integrates five key principles: active learning, environmental enrichment, caregiver engagement, a strengths-based approach, and high dosage (ClinicalTrials.gov identifier NCT05568264). METHODS: We will recruit 192 infants at risk for neuromotor delay who were admitted to the NICU. Infants will be randomized to either a standard-of-care group or an intervention group; infants in both groups will have access to standard-of-care services. The intervention is initiated in the NICU and continues in the infant's home until 12 months of age. Participants will receive twice-weekly physical therapy sessions and caregiver-guided daily activities, assigned by the therapist, targeting collaboratively identified goals. We will use various standardized clinical assessments (General Movement Assessment; Bayley Scales of Infant and Toddler Development, 4th Edition (Bayley-4); Test of Infant Motor Performance; Pediatric Quality of Life Inventory Family Impact Module; Alberta Infant Motor Scale; Neurological, Sensory, Motor, Developmental Assessment; Hammersmith Infant Neurological Examination) as well as novel technology-based tools (wearable sensors, video-based pose estimation) to evaluate neuromotor status and development throughout the course of the study. The primary outcome is the Bayley-4 motor score at 12 months; we will compare scores in infants receiving the intervention vs. standard-of-care therapy.

Impact of prenatal exposure characterization on early risk detection: Methodologic insights for the HEALthy Brain and Child Development (HBCD) study.

BACKGROUND: A major challenge in prenatal drug exposure research concerns the balance of measurement quality with sample sizes necessary to address confounders. To inform the selection of optimal exposure measures for the HEALthy Brain and Child Development (HBCD) Study, we employed integrated analysis to determine how different methods used to characterize prenatal tobacco exposure influence the detection of exposure-related risk, as reflected in normal variations in birth weight. METHODS: Participants were N = 2323 mother-infant dyads derived from 7 independent developmental cohorts harmonized on measures of exposure, outcome (birthweight), and covariates. We compared estimates of PTE-related effects on birthweight derived from linear regression models when PTE was categorized dichotomously based on any fetal exposure (30% exposed; 69% not exposed); versus categorically, based on common patterns of maternal smoking during pregnancy (never smoked 69%; quit smoking 16%; smoked intermittently 2%; smoked persistently 13%). We secondarily explored sex differences in PTE-birthweight associations across these categorization methods. RESULTS: When PTE was categorized dichotomously, exposure was associated with a - 125-g difference in birthweight (95% C.I. -173.7 - -76.6, p < .0001). When PTE was characterized categorically based on maternal smoking patterns, however, exposure was associated with either no difference in birthweight if mothers quit smoking by the end of the first trimester (B = -30.6, 95% C.I. -88.7-27.4, p = .30); or a - 221.8 g difference in birthweight if mothers did not [95% C.I. (-161.7 to -282.0); p < .001]. Qualitative sex differences were also detected though PTE x sex interactions did not reach statistical significance. Maternal smoking cessation during pregnancy was associated with a 239.3 g increase in birthweight for male infants, and a 114.0 g increase in birthweight for females infants (p = .07). CONCLUSIONS: Categorization of PTE based on patterns of maternal smoking rather than the presence or absence of exposure alone revealed striking nuances in estimates of exposure-related risk. The described method that captures both between-individual and within-individual variability in prenatal drug exposure is optimal and recommended for future developmental investigations such as the HBCD Study.

Reducing Severe Tracheal Intubation Events Through an Individualized Airway Bundle.

BACKGROUND: Neonatal tracheal intubation (TI) is a high-risk procedure associated with adverse safety events. In our newborn and infant ICU, we measure adverse tracheal intubation-associated events (TIAEs) as part of our participation in National Emergency Airway Registry for Neonates, a neonatal airway registry. We aimed to decrease overall TIAEs by 10% in 12 months. METHODS: A quality improvement team developed an individualized approach to intubation using an Airway Bundle (AB) for patients at risk for TI. Plan-do-study-act cycles included AB creation, simulation, unit roll out, interprofessional education, team competitions, and adjusting AB location. Outcome measure was monthly rate of TIAEs (overall and severe). Process measures were AB initiation, AB use at intubation, video laryngoscope (VL) use, and paralytic use. Balancing measure was inadvertent administration of TI premedication. We used statistical process control charts. RESULTS: Data collection from November 2016 to August 2020 included 1182 intubations. Monthly intubations ranged from 12 to 41. Initial overall TIAE rate was 0.093 per intubation encounter, increased to 0.172, and then decreased to 0.089. System stability improved over time. Severe TIAE rate decreased from 0.047 to 0.016 in June 2019. AB initiation improved from 70% to 90%, and AB use at intubation improved from 18% to 55%. VL use improved from 86% to 97%. Paralytic use was 83% and did not change. The balancing measure of inadvertent TI medication administration occurred once. CONCLUSIONS: We demonstrated a significant decrease in the rate of severe TIAEs through the implementation of an AB. Next steps include increasing use of AB at intubation.

The General Movements Assessment in Neonates With Hypoxic Ischemic Encephalopathy.

BACKGROUND: Clinical measures after birth and studies such as electroencephalogram (EEG) and brain imaging do not fully predict neurodevelopmental outcomes of infants with hypoxic-ischemic encephalopathy. Early detection of adverse neurologic outcomes, and cerebral palsy in particular, in high-risk infants is essential for ensuring timely management. The General Movements Assessment is a tool that can be used in the early detection of cerebral palsy in infants with brain injury. The majority of studies on the General Movements Assessment in the late preterm and term population were performed prior to the introduction of therapeutic hypothermia. AIMS: To apply the General Movements Assessment in late preterm and term infants with hypoxic-ischemic encephalopathy (including those who received therapeutic hypothermia), to determine if clinical markers of hypoxic-ischemic encephalopathy predict abnormal General Movements Assessment findings, and to evaluate interrater reliability of the General Movements Assessment in this population. Study design: Pilot prospective cohort study Subjects: We assessed 29 late preterm and full-term infants with mild, moderate, and severe hypoxic-ischemic encephalopathy in Philadelphia, PA. RESULTS: Most infants' general movements normalized by the fidgety age. Only infants with moderate or severe hypoxic-ischemic encephalopathy had abnormal general movements in both the writhing and the fidgety ages (n = 6). Seizure at any point during the initial hospitalization was the clinical sign most predictive of abnormal general movements in the fidgety age (sensitivity 100%, specificity 55%, positive predictive value 40%, negative predictive value 100%). Interrater reliability was greatest during the fidgety age (κ = 0.67). CONCLUSIONS: Seizures were the clinical predictor most closely associated with abnormal findings on the General Movements Assessment. However, clinical markers of hypoxic-ischemic encephalopathy are not fully predictive of abnormal General Movements Assessment findings. Larger future studies are needed to evaluate the associations between the General Movements Assessment and childhood neurologic outcomes in patients with hypoxic-ischemic encephalopathy who received therapeutic hypothermia.

Starting at Birth: An Integrative, State-of-the-Science Framework for Optimizing Infant Neuromotor Health.

Numerous conditions and circumstances place infants at risk for poor neuromotor health, yet many are unable to receive treatment until a definitive diagnosis is made, sometimes several years later. In this integrative perspective, we describe an extensive team science effort to develop a transdiagnostic approach to neuromotor health interventions designed to leverage the heightened neuroplasticity of the first year of life. We undertook the following processes: (1) conducted a review of the literature to extract common principles and strategies underlying effective neuromotor health interventions; (2) hosted a series of expert scientific exchange panels to discuss common principles, as well as practical considerations and/or lessons learned from application in the field; and (3) gathered feedback and input from diverse stakeholders including infant caregivers and healthcare providers. The resultant framework was a pragmatic, evidence-based, transdiagnostic approach to optimize neuromotor health for high-risk infants based on four principles: (a) active learning, (b) environmental enrichment, (c) caregiver engagement, and (d) strength-based approaches. In this perspective paper, we delineate these principles and their potential applications. Innovations include: engagement of multiple caregivers as critical drivers of the intervention; promoting neuromotor health in the vulnerability phase, rather than waiting to treat neuromotor disease; integrating best practices from adjacent fields; and employing a strengths-based approach. This framework holds promise for implementation as it is scalable, pragmatic, and holistically addresses both the needs of the infant and their family.

Improving the Resident Educational Experience in a Level IV Neonatal/Infant Intensive Care Unit.

The neonatal/infant intensive care unit (N/IICU) at the Children's Hospital of Philadelphia is a 98-bed, level IV unit through which second-year pediatric residents rotate monthly. We developed a quality improvement project to improve the resident educational experience using goal setting. Primary objectives were to increase resident educational goal identification to 65% and goal achievement to 85% by June 2017. Secondary objectives were to (1) increase in-person feedback from fellows and/or attendings to 90% by June 2017 and (2) sustain improvements through June 2018. METHODS: The quality improvement team developed a driver diagram and administered a baseline survey to 48 residents who had rotated through the N/IICU in the 18 months before the project. Plan-Do-Study-Act cycles targeted project awareness and trialing of 3 different methods to elicit goals and track feedback, from July 2016 through June 2018. RESULTS: The baseline survey response rate was 52% (n = 25). Among 60 rotating residents, the median resident-reported rate of goal achievement increased from 37.5% to 50%, and residents receiving in-person feedback increased from 25% to 50%. Of the 63% (n = 38) of residents who participated in data collection, goal identification and achievement increased from 38% to 100% between academic year 2016 and academic year 2017, and in-person feedback increased from 24% to 82%. CONCLUSIONS: Instituting a goal-setting framework for residents during their N/IICU rotation increased goal achievement and in-person feedback. Consistent resident participation in postrotation data collection made measuring project outcomes challenging. These data support goal-oriented learning as an approach to enhance learner engagement and improve goal achievement.

Association Between Video Laryngoscopy and Adverse Tracheal Intubation-Associated Events in the Neonatal Intensive Care Unit.

The effect of video laryngoscopy on adverse events during neonatal tracheal intubation is unknown. In this single site retrospective cohort study, video laryngoscopy was independently associated with decreased risk for adverse events during neonatal intubation.

Why do children with severe bronchopulmonary dysplasia not attend neonatal follow-up care? Parental views of barriers.

AIM: To assess in children with severe bronchopulmonary dysplasia at a corrected age of 18-36 months: (i) Neonatal follow-up clinic attendance rates; (ii) Parent-identified reasons for difficulty attending neonatal follow-up. METHODS: Mixed methods study utilising semi-structured phone interviews with parents of infants eligible for follow-up with severe bronchopulmonary dysplasia (defined as gestational age <32 weeks and requiring ≥30% FiO2 and/or >2 L nasal cannula at 36 weeks post-menstrual age) at 18-36 months corrected age. Questions addressed barriers to neonatal follow-up attendance. Enrolment continued to saturation (no new themes emerging). RESULTS: A total of 58 infants (69% male) were enrolled. Infants were 26 ± 2.1 weeks gestational age and birth weight 794 ± 262 g. At 28 ± 5.8 months corrected age, 26% had never attended neonatal follow-up clinic, 16% stopped attending before discharge, 5% were discharged, and 53% were still followed. Longer travel distance from home to follow-up clinic was associated with poorer attendance. Parent-generated items related to neonatal follow-up barriers were coded into four themes: Logistics, Time, Perceptions and Emotional Stress. CONCLUSION: Despite high risk of developmental delay in infants with severe bronchopulmonary dysplasia, neonatal follow-up rates are suboptimal. Careful review of parent-identified barriers could be utilised to develop targeted strategies to improve neonatal follow-up attendance in this high-risk population.

Complex Surgical Infants Benefit From Postdischarge Telemedicine Visits.

BACKGROUND: Transition from the neonatal intensive care unit (NICU) to home is challenging for caregivers of complex surgical infants. A prospective, observational cohort pilot study using telemedicine to improve transition was implemented in a quaternary level IV NICU. PURPOSE: (1) To assess, identify, and resolve patient care concerns in the immediate postdischarge period. (2) To improve caregiver knowledge and care practices. DESIGN METHODS: Caregivers of medically complex infants participated in telemedicine visits with neonatal providers within 1 week of discharge. Providers reviewed infant health, equipment use, and outpatient follow-up. Video was used to visualize the infant, home environment, and care practices. Caregivers completed a postvisit satisfaction survey. RESULTS: Ninety-three visits were performed from May 2015 to March 2017. Seventy-six percent of visits were postsurgery patients. Seventy-eight postdischarge issues were identified: medication administration (13%), respiratory (19%), feeding (33%), and surgical site (35%). Fifty percent of caregivers reported that telemedicine visits prevented an additional call or visit to a clinician; 12% prompted an earlier visit (n = 93). Caregiver satisfaction rating was high. Median estimation of total mileage saved by respondents was 1755 miles. CONCLUSIONS: Postdischarge telemedicine visits with complex surgical NICU graduates identify clinical issues, provide caregivers with support, and save travel time. Advanced practice nurses are instrumental in patient recruitment, with patient visits, and in providing postdischarge continuity of care. Barriers to implementation were identified. IMPLICATION FOR PRACTICE AND RESEARCH: A randomized controlled study is warranted to measure the value of telemedicine visits for specific patient cohorts.
