Matemal Concepts and Expectations regarding a Preterm Infant

The objective of the present study was: (a) to identify the concerns, verbally expressed, of 50 mothers regarding their preterm infants (PT) and then compare their verbal expression with those of 25 mothers of full-term infants (FT): and (b) to correlate the mothers` verbal expressions with maternal and infant variables. The following instruments were used to compose and characterize the sample: Structure Clinical Interview for DSM III-R Non-Patient (SCID/NP), State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), and medical charts. Results showed that there was no difference between groups in term of mothers` expectations and conceptualizations, both groups exhibited predominantly positive expectations and concepts. In comparison with FT mothers, PT mothers verbally expressed more feelings and reactions predominantly negative or conflicting in relation to infant birth. Higher levels of maternal anxiety and depression in the PT Group were correlated with more verbal expressions about negative or conflicting emotions. In addition, lower birth weight, higher neonatal risk and longer length of stay in intensive care nursery of the infants were related with more negative or conflicting concepts by the mothers.

BORN AT 27 WEEKS OF GESTATION WITH CLASSICAL PKU: CHALLENGES OF DIETETIC MANAGEMENT IN A VERY PRETERM INFANT

Only few cases of classical phenylketonuria (PKU) in premature infants have been reported. Treatment of these patients is challenging due to the lack of a phenylalanine-free amino acid solution for parenteral infusion. The boy was born at 27 weeks of gestation with a weight of 1000 g (P10). He received parenteral nutrition with a protein intake of 3 g/kg/day. On day 7 he was diagnosed with classical PKU (genotype IVS10-11G>A/IVS12+ 1G>A) due to highly elevated phenylalanine (Phe) level in newborn screening (2800 micromol/L). His maximum plasma Phe level reached 3696 micromol/L. Phe intake was stopped for 4 days. During this time the boy received intravenous glucose and lipids as well as little amounts of Phe-free formula by a nasogastric tube. Due to a deficit of essential amino acids and insufficient growth, a parenteral nutrition rich in branched-chain amino-acids and relatively poor in Phe was added, in order to promote protein synthesis without overloading in Phe. Under this regimen, Phe plasma levels normalized on day 19 when intake of natural protein was started. The boy has now a corrected age of 2 years. He shows normal growth parameters and psychomotor development. Despite a long period of highly elevated Phe levels in the postnatal period our patient shows good psychomotor development. The management of premature infants with PKU depends on the child's tolerance to enteral nutrition. It demands an intensive follow-up by an experienced team and dedicated dietician. Appropriate Phe-free parenteral nutrition would be necessary especially in case of gastro-intestinal complications of prematurity.

Delayed Cyclic Activity Development on Early Amplitude-Integrated EEG in the Preterm Infant with Brain Lesions.

Background: Maturation of amplitude-integrated electroencephalogram (aEEG) activity is influenced by both gestational age (GA) and postmenstrual age. It is not fully known how this process is influenced by cerebral lesions. Objective: To compare early aEEG developmental changes between preterm newborns with different degrees of cerebral lesions on cranial ultrasound (cUS). Methods: Prospective cohort study on preterm newborns with GA <32.0 weeks, undergoing continuous aEEG recording during the first 84 h after birth. aEEG characteristics were qualitatively and quantitatively evaluated using pre-established criteria. Based on cUS findings three groups were formed: normal (n = 78), mild (n = 20), and severe cerebral lesions (n = 6). Linear mixed models for repeated measures were used to analyze aEEG maturational trajectories. Results: 104 newborns with a mean GA (range) 29.5 (24.4-31.7) weeks, and birth weight 1,220 (580-2,020) g were recruited. Newborns with severe brain lesions started with similar aEEG scores and tendentially lower aEEG amplitudes than newborns without brain lesions, and showed a slower development of the cyclic activity (p < 0.001), but a more rapid increase of the maximum and minimum aEEG amplitudes (p = 0.002 and p = 0.04). Conclusions: Preterm infants with severe cerebral lesions manifest a maturational delay in the aEEG cyclic activity already early after birth, but show a catch-up of aEEG amplitudes to that of newborns without cerebral lesions. Changes in the maturational aEEG pattern may be a marker of severe neurological lesions in the preterm infant.

Surgical complications due to postnatal cytomegalovirus infection in a preterm infant with malrotation.

We report a case of an extremely preterm infant with intestinal malrotation who contracted postnatal systemic cytomegalovirus (CMV) infection with a complicated intestinal evolution requiring repeated surgical interventions and antiviral treatment. This report is to emphasize that prolonged gastrointestinal symptoms in extremely preterm infants fed with non-pasteurized breast milk should lead to suspicion of CMV infection. The importance of preventive measures when feeding very preterm infants with breast milk needs to be considered. Furthermore, the indications for antiviral treatment, in particular in preterm infants, need to be clarified.

Early relationship between very preterm infant and mother: The role of infant, maternal and dyadic factors

Pienipainoisen keskosen ja äidin varhainen suhde: Lapsen, äidin ja dyadisten muuttujien vaikutus Tämän tutkimuksen tavoitteena oli tutkia keskosvauvan ja äidin varhaista suhdetta. Tutkimuksessa selvitettiin myös vauvan itkukäyttäytymisen, vauvan sylissä olon ja äidin masentuneisuuden yhteyttä äidin ja keskosvauvan varhaiseen suhteeseen. Tutkimusryhmät koostuivat 32:sta (tutkimus I-II) ja 38:sta (tutkimus III-IV) keskosena syntyneestä vauvasta (syntymäpaino < 1501 g tai GI < 32 viikkoa) sekä 46:sta täysiaikaisena syntyneestä terveestä verrokkivauvasta. Lapsen ja äidin vuorovaikutusta arvioitiin 6 ja 12 kuukauden iässä (korjattu ikä) PCERAmenetelmällä. Äidin mielikuvia lapsestaan tutkittiin WMCI-haastattelulla, kun lapsi oli 12 kuukautta. Baby Day Diary -menetelmää käytettiin vauvan itkukäyttäytymisen ja sylissä olon keston mittaamisessa vauvan ollessa 5 kuukautta. Äidin masentuneisuutta arvioitiin EDPS-lomakkeella, kun lapsi oli 6 kuukautta. Tulokset osoittivat, että turvallisten kiintymyssuhdemielikuvien määrä tai vuorovaikutuksen laatu eivät keskosvauvan äideillä eronneet täysiaikaisina syntyneiden vauvojen äitien vastaavista. Ryhmien välillä ei löytynyt eroja myöskään dyadisen vuorovaikutuksen laadussa. Keskosena syntyneet lapset olivat kuitenkin vetäytyvämpiä ja heillä oli laadullisesti heikommat keskittymisen ja leikin taidot vuorovaikutustilanteessa 12 kuukauden iässä täysiaikaisina syntyneisiin lapsiin nähden. Lisäksi äidin masentuneisuus ja lapsen pitkittynyt itkuisuus olivat negatiivisessa yhteydessä vuorovaikutuksen laatuun keskosvauvojen ryhmässä. Vauvan itkukertojen määrän, sylissä olon keston sekä äidin ja vauvan vuorovaikutuksen laadun välillä löytyi positiivinen yhteys ainoastaan keskosena syntyneiden lasten ryhmässä. Tulostemme perusteelle toteamme, että lapsen ennenaikainen syntymä itsessään ei näytä muodostavan riskiä äidin vuorovaikutuksen laadulle tai turvalliselle kiintymyssuhteelle. Yhdessä muiden riskitekijöiden kanssa keskosuus kuitenkin altistaa vauvat ja heidän äitinsä varhaisen vuorovaikutuksen ongelmille. Lisäksi tuloksemme viittaavat siihen, että vauvan itku ja siitä seuraava sylissä olo toimivat suojaavana mekanismina pienipainoisen keskosen ja äidin varhaisessa suhteessa.

Breastfeeding preterm infant from the delivery ward via nicu to home

The aim of this study was to examine how to support breastfeeding of preterm infants immediately after birth in the delivery ward, during their hospital stay in a neonatal intensive care unit (NICU), and at home after hospital discharge. Specifically, the role of early physical contact, maternal breastfeeding attitude, and an internet-based peer support group were investigated. The delivery ward practices concerning the implementation of early physical contact between a mother and her infant admitted to a NICU were examined by a structured survey in two hospitals. An Internet-based, breastfeeding peer-support intervention for the mothers of preterm infants was developed and tested in a randomized controlled design with one year follow-up. The main outcomes were the duration of exclusive and overall breastfeeding, expressing milk, and maternal attitude. In addition, the perceptions of mothers of preterm infants were investigated by analyzing the peer-support group discussions with a qualitative approach. The implementation of early physical contact was different between the two hospitals studied and was based more on hospital routines than the physiological condition of the infant. Preterm infants, who were born before a gestational age (GA) of 32 weeks, were hardly ever allowed to have early contact with their mothers. Both, a higher GA and early physical contact predicted earlier initiation and increased frequency of breastfeeding in the NICU. A maternal breastfeeding-favorable attitude predicted increased frequency of breastfeeding in the NICU and also a longer duration of overall breastfeeding. The actual duration of breastfeeding was, however, shorter than the mothers intended in advance. The internet-based, peer-support intervention had no effect on the duration of breastfeeding, expressing milk, or maternal attitude. The participating mothers enjoyed the possibility of sharing their experiences of preterm infants with other mothers in similar situations. Some of the mothers also experienced being given useful advice for breastfeeding. Based on the mothers’ discussions, a process of breastfeeding preterm infants was created. This included some paradoxical elements in the NICU where, for example, breast milk was emphasized over breastfeeding and support in the hospital varied. Hospital discharge was a critical point, when the mothers faced breastfeeding in reality. Over time, the mothers assimilated their breastfeeding experience into part of being a mother. The care practices related to early physical contact in delivery wards need to be re-evaluated to allow more infants to have a moment with the mother. Maternal attitude could be screened prenatally and attitude-focused interventions developed. Breastfeeding support in the NICU should be standardized. Internet-based breastfeeding peer-support intervention was feasible but additional research is needed.

Parent’s experiences of feeding their preterm infant in Neonatal Units in Sweden. : Ethnographic design

Introduction: Studies have shown that having a preterm infant may cause stress and powerlessness for parents. It is important to support parents around the feeding situation, and that the Neonatal Intensive Care Unit (NICU) has appropriate space and place to help the family to bond to each other. For the healthcare professionals it is important to promote skin-to-skin contact and breastfeeding; particularly for preterm infants. There are many studies on parent’s experiences of NICUs and a few studies on parent’s experiences of feeding their infant in the NICU. Objective: The objective of this study was to explore parents experiences of feeding their infant in the NICU. Design: The study was conducted using an ethnographic design. Results: A global theme of ‘The journey in feeding’ was developed from four organising themes: ‘Ways of infant feeding’; ‘Environmental influences’; ‘Relationships’ and ‘Emotional factors’. These themes illustrate the challenges mothers reported with different methods of feeding. The environment had a big impact on parent’s experiences of infant feeding. Some mothers felt that breastfeeding seemed unnatural because their infant was so tiny but breastfeeding and skin-to-skin contact helped them to bond to their infant. The mothers thought it was difficult to keep up with the milk production by only pumping. Routines were not inviting parents to find their own rhythm. They also felt stressed about the weighing. Healthcare professionals had positive and negative influences on the parents. Conclusions: This study demonstrates that while all parents expressed the wish to breastfeed, their ‘journey in feeding’ was highly influenced by method of feeding, environmental, relational and emotional factors. The general focus upon routines and assessing milk intake generated anxiety and reduced relationality. Midwives and neonatal nurses need to ensure that they emphasise and support the relational aspects of parenting and avoid over-emphasising milk intake and associated progress of the infant

Growth and developmental outcomes of the extremely preterm infant

Objetive: To provide information for pediatricians and neonatologists to create realistic outcome expectations and thus help plan their actions. Sources of data: Searches were made of the Cochrane Library, MEDLINE, and Lilacs databases. Summary of the findings: The assessment of growth and development over the first 2-3 years must adjust chronological age with respect of the degree of prematurity. There is special concern regarding the prognoses of small for gestational age preterm infants, and for those with bronchopulmonary dysplasia. Attention must be directed towards improving the nutrition of extremely low birth weight infants during their first years of life; these infants have high prevalence levels of failure to catch-up on growth, diseases and rehospitalizations during their first 2 years. They are frequently underweight and shorter than expected during early childhood, but delayed catch-up growth may occur between 8 and 14 years. Extremely low birth weight infants are at increased risk of neurological abnormalities and developmental delays during their first years of life. Educational, psychological, and behavioral problems are frequent during school years. Teenage and adult outcomes show that although some performance differences persist, social integration is not impaired. Conclusions: The growth and neurodevelopment of all ELBW infants must be carefully monitored after discharge, to ensure that children and their families receive adequate support and intervention to optimize prognoses.

Congenital diaphragmatic hernia in the preterm infant.

BACKGROUND: Congenital diaphragmatic hernia (CDH) remains a significant cause of death in newborns. With advances in neonatal critical care and ventilation strategies, survival in the term infant now exceeds 80% in some centers. Although prematurity is a significant risk factor for morbidity and mortality in most neonatal diseases, its associated risk with infants with CDH has been described poorly. We sought to determine the impact of prematurity on survival using data from the Congenital Diaphragmatic Hernia Registry (CDHR). METHODS: Prospectively collected data from live-born infants with CDH were analyzed from the CDHR from January 1995 to July 2009. Preterm infants were defined as <37 weeks estimated gestational age at birth. Univariate and multivariate logistic regression analysis were>performed. RESULTS: During the study period, 5,069 infants with CDH were entered in the registry. Of the 5,022 infants with gestational age data, there were 3,895 term infants (77.6%) and 1,127 preterm infants (22.4%). Overall survival was 68.7%. A higher percentage of term infants were treated with extracorporeal membrane oxygenation (ECMO) (33% term vs 25.6% preterm). Preterm infants had a greater percentage of chromosomal abnormalities (4% term vs 8.1% preterm) and major cardiac anomalies (6.1% term vs 11.8% preterm). Also, a significantly higher percentage of term infants had repair of the hernia (86.3% term vs 69.4% preterm). Survival for infants that underwent repair was high in both groups (84.6% term vs 77.2% preterm). Survival decreased with decreasing gestational age (73.1% term vs 53.5% preterm). The odds ratio (OR) for death among preterm infants adjusted for patch repair, ECMO, chromosomal abnormalities, and major cardiac anomalies was OR 1.68 (95% confidence interval [CI], 1.34-2.11). CONCLUSION: Although outcomes for preterm infants are clearly worse than in the term infant, more than 50% of preterm infants still survived. Preterm infants with CDH remain a high-risk group. Although ECMO may be of limited value in the extremely premature infant with CDH, most preterm infants that live to undergo repair will survive. Prematurity should not be an independent factor in the treatment strategies of infants with CDH.

Non-nutritive sucking and the preterm infant

Background. Preterm birth is major public health problem. Preterm infants face a post-natal environment that their under developed systems are inapt to manage. Developmentally supportive individualized care has demonstrated positive outcomes in minimizing resulting negative effects. Non-nutritive sucking (NNS) interventions are thought to promote the development of the suck-swallow-breathe mechanism and a calming tool. It is hypothesized that growth and development is maintained by strengthened sucking skills and stable behavioral states.^ Objective. To determine the importance of non-nutritive sucking (NNS) on outcomes that are clinically relevant to the preterm infant population.^ Methods. A computerized search of MEDLINE and PUBMED databases during the period of 1975 and May 2011 was conducted. Relevant articles were selected using published criteria for detecting clinically validated studies. The search yielded 10 randomized controlled studies relative to the outcomes of interest: weight gain, time to full feeds, time to discharge from hospital, and pain response.^ Results. NNS was found to decrease significantly the length of hospitalization in preterm infants. Although positive results were reported in some of the studies, the results did not show a consistent benefit of NNS with respect to other major clinical variables. NNS was shown to reduce distress following painful stimuli.^ Conclusion. Although NNS shows promise for the development of preterm infants, there is lack of agreement concerning some of the outcomes of interest. Evidence does support NNS's positive contribution to early hospital discharge and pain relief. Future research should focus on long-term, comparable outcomes. ^
