Advances in Neonatal Care最新文献

Background: The COVID-19 pandemic affected the maternal-infant dyad, especially due to visitation restrictions in neonatal units. These changes may impact the psychological, physical, and developmental health of mothers and newborns.

Purpose: This systematic review evaluates the impact of enforced separation and restrictive visitation policies in neonatal units during the pandemic, focusing on the maternal-infant dyad.

Data sources: Data sources include CINAHL, MEDLINE, Web of Science, APA PsycINFO, Academic Search Ultimate, and Embase, covering studies published between 2020 and 2024.

Study selection: A detailed search was conducted using terms related to COVID-19, maternal and neonatal health, and visitation restrictions in neonatal units. Articles were included if they were peer-reviewed, written in English, and focused on the impact of visitation restrictions on maternal and neonatal health.

Data extraction: The data extraction process began with 789 references. After removing duplicates, we screened titles and abstracts. We then conducted a full-text assessment of the remaining studies, selecting 14 that met the inclusion criteria.

Results: The analysis showed significant emotional, psychological, and developmental impacts on mothers and newborns due to pandemic-induced separation and inconsistent policies. It highlighted depressive symptoms, stress, bonding disruptions, and the effectiveness of virtual bonding.

Implications for practice and research: The review emphasizes the need for family-centered care, coping strategies, and virtual bonding in neonatal units. It calls for culturally sensitive policies to support mothers and infants during crises. The review also highlights the importance of studying the long-term effects of pandemic-induced separations and improving support for future health emergencies.

Background: Treprostinil is a prostacyclin analogue that is frequently used in the pediatric and adult population to treat pulmonary hypertension; however, it is not often a drug of choice for patients in the neonatal intensive care unit (NICU).

Purpose: To evaluate the efficacy of treprostinil as a treatment for pulmonary hypertension of the neonate.

Data sources: Electronic databases such as PubMed, CINAHL, and Embase were used for this literature review. Twelve articles within the last 10 years (2014-2024) were included in this review.

Study selection: 136 articles were identified and primary research studies published in English and with patients younger than one year of age were included. Duplicates were removed and studies discussing genetics and congenital heart disease were excluded.

Data extraction: Abstracts were reviewed and articles referencing treprostinil use in the NICU were included for review. Independent extraction was completed by author.

Results: Findings showed treprostinil to have a therapeutic benefit in infants with congenital diaphragmatic hernias and possibly with premature infants. Some adverse effects were noted, one of which included hypotension; however, management strategies exist to mitigate this effect.

Implications for practice and research: Initiating treprostinil in the NICU may help decrease the severity of persistent pulmonary hypertension of the newborn (PPHN) which can help reduce neonatal morbidity and mortality. Future research is needed to determine the optimal timeframe to initiate treprostinil in the NICU; the duration of treatment; use in other conditions that can cause PPHN (i.e. meconium aspiration syndrome); and the other potential effects it may have for the preterm infant.

Background: Feeding skill acquisition is commonly a limiting factor determining when an infant born prematurely can be discharged.

Purpose: This study aimed to determine if the addition of a novel feeding progression algorithm (combination of objective data from a suck measurement device and slow flow/low variability nipples) to current neonatal intensive care unit (NICU) standards could decrease feeding-related length of stay (primary outcome). We hypothesized that by timing the initiation of oral feedings to coincide with adequate sensory-motor skill development, feeding-related length of stay may be decreased.

Methods: This was a prospective intervention study, with a historical control cohort, of infants born less than 30 weeks' gestational age without comorbidities affecting feeding skill acquisition at a Regional Level III-S NICU at a women and infant's hospital in Louisiana. A novel feeding progression algorithm utilized objective assessment of sucking to determine progression in nipple flow rates with slow flow/low variability nipples (flow rates from 0 to 9 mL/min) for infants receiving intervention (n = 18). Thirty-six controls who did not receive the feeding progression algorithm were identified via electronic medical record retrospective chart review.

Results: Eighteen completed the study. Compared to the control group, infants receiving feeding interventions had delayed sequencing initiation, extended time between initially off positive pressure ventilation and initiation of sequencing, and decreased feeding-related length of stay, with similar total length of stay.

Implications for practice and research: This study adds to existing research supporting the effectiveness of novel feeding progression algorithms and interventions to support the health and outcomes of infants born prematurely. Future research should focus on implementation studies for feeding progression algorithm integration into standard NICU care.

Background: Preterm infants face challenges to feed orally, which may lead to failure to thrive. Oral feeding skill development requires intact neurobehaviors. Early life stress results in DNA methylation of NR3C1 and HSD11B2, which may disrupt neurobehaviors. Yet, the extent to which early life stress impairs oral feeding skill development and the biomechanism whereby this occurs remains unknown. Our team is conducting an NIH funded study (K23NR019847, 2022-2024) to address this knowledge gap.

Purpose: To describe an ongoing study protocol to determine the extent to which early life stress, reflected by DNA methylation of NR3C1 and HSD11B2 promoter regions, compromises oral feeding skill development.

Methods: This protocol employs a longitudinal prospective cohort study. Preterm infants born between 26 and 34 weeks gestational age have been enrolled. We evaluate early life stress, DNA methylation, cortisol reactivity, neurobehaviors, and oral feeding skill development during neonatal intensive care unit hospitalization and at 2-week post-discharge.

Results: To date, we have enrolled 70 infants. We have completed the data collection. Currently, we are in the data analysis phase of the study, and expect to disseminate the findings in 2025.

Implications for practice and research: The findings from this study will serve as a foundation for future clinical and scientific inquiries that support oral feeding and nutrition, reduce post-discharge feeding difficulties and lifelong risk of maladaptive feeding behaviors and poor health outcomes. Findings from this study will also provide further support for the implementation of interventions to minimize stress in the vulnerable preterm infant population.

Background: Nonpharmacological methods such as white noise and therapeutic touch can be used in pain management in neonates.

Purpose: This randomized controlled study evaluated the effects of white noise and therapeutic touch during heel lance procedures on pain, comfort levels, and physiological parameters in healthy neonates.

Methods: This parallel, randomized controlled study was conducted in the Obstetrics and Gynecology Service of a regional hospital. The sample comprised 160 neonates with gestational ages of >35 weeks randomly assigned to 4 groups (white noise [WN], therapeutic touch [TT], white noise + therapeutic touch [WT], and control [CG] group). Pain and comfort levels were evaluated according to the Neonatal Infant Pain Scale, and the COMFORTneo Scale. The primary outcomes were pain and comfort levels, and the secondary outcomes were heart rate and SpO2 levels. The Kruskal-Wallis test was used to compare the scale scores among groups.

Results: There were significant differences among groups in terms of Neonatal Infant Pain Scale and COMFORTneo scores (P < .05). The pain scores for the white noise, therapeutic touch, and white noise + therapeutic touch groups were 4.2 ± 2.0, 5.2 ± 1.6, and 3.3 ± 1.7, respectively. There was a significant difference in average heart rate during the heel lance procedure among the groups (P < .05). Pain scores of the intervention groups were lower compared to the control group.

Implications for practice and research: The combination of white noise and therapeutic touch was more effective in reducing pain and increasing comfort levels. Nurses could reduce procedural pain by applying these pain relief methods.

Background: Point-of-care ultrasound (POCUS) in the neonatal intensive care unit (NICU) is becoming increasingly utilized, with the focus of training aimed at physicians. However, the role of neonatal nurse practitioners (NNPs) in the development of POCUS programs is not well described.

Purpose: To describe the NNP role in the implementation of a NICU POCUS program and exemplify the potential to expand the professional scope and educational advancement of NNPs.

Methods: In 2018, a multidisciplinary team assembled to develop a POCUS program in the NICU at Lucile Packard Children's Hospital (LPCH). Three NNPs received formal POCUS training in order to provide onsite training, perform and supervise POCUS imaging, and participate in quality assurance sessions. NNPs also assisted with the development of a REDCap database and imaging protocols.

Results: The LPCH POCUS NNP providers contributed to the advancement of the profession by practicing to the full scope of their role, providing leadership in program development, research, and education. Incorporating NNPs into the programmatic structure of a POCUS program can be a model for others. With advancing skill set, NNPs can be positioned to be national leaders and educators.

Implications for practice and research: NICUs developing POCUS programs can benefit from the integration of NNPs to serve as consistent content experts to expand the number of trained providers while assuring the quality of image capture. POCUS is becoming increasingly essential to the care of newborns. NNPs can play a central role in performing POCUS, participating in quality improvement and research, and educating other NICU providers.

Background: More than 350,000 U.S. infants are admitted to the neonatal intensive care unit (NICU) annually and likely experience discomfort. Although nurse perceptions of infant symptoms, suffering, and quality of life (QOL) are valuable, the availability of standardized assessment tools to measure these concepts are limited.

Purpose: To provide preliminary evidence of the internal structure, reliability, and validity of the Nurse Perception of Infant Condition (NPIC) scale.

Methods: Infants were enrolled from a Level IV NICU in the U.S. Midwest. Nurses reported on their perceptions of the infant symptom experience and their expectations for infant survival. Weekly behavioral observations of infants were obtained before and after standard delivery of care to obtain a comfort score.

Results: 237 nurses who cared for 73 infants completed 569 surveys over 28 months. All NPIC items were significantly correlated with each other ( P < .001). Factor analysis revealed strong evidence of a 2-factor structure (survival and suffering subscales). Both subscales demonstrated good to excellent internal consistency. Together the 2 factors explained 82% of the variability in the scale responses. Limited validity evidence was found.

Implications for practice and research: Evidence was found to support the internal structure and reliability of the NPIC scale. However, further item development and refinement is needed to increase the utility NPIC scale in clinical and research settings. The development of improved assessments of the infant NICU experience is warranted. Nurse perceptions of infant suffering or poor QOL may have implications for their expectations for infant survival and possibly care delivery.
