    Expectant management of early onset, severe pre-eclampsia: perinatal outcome

    BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2000
    D. R. Hall Consultant
    Objective To evaluate the perinatal outcome of expectant management of early onset, severe pre-eclampsia. Design Prospective case series extending over a five-year period. Setting Tertiary referral centre. Population All women (n= 340) presenting with early onset, severe pre-eclampsia, where both mother and the fetus were otherwise stable. Methods Frequent clinical and biochemical monitoring of maternal status with careful blood pressure control. Fetal surveillance included six-hourly heart rate monitoring, weekly Doppler and ultrasound evaluation of the fetus every two weeks. All examinations were carried out in a high care obstetric ward. Main outcome measures Prolongation of gestation, perinatal mortality rate, neonatal survival and major complications. Results A mean of 11 days were gained by expectant management. The perinatal mortality rate was 24/1000 (, 1000 g/7 days) with a neonatal survival rate of 94%. Multivariate analysis showed only gestational age at delivery to be significantly associated with neonatal outcome. Chief contributors to neonatal mortality and morbidity were pulmonary complications and sepsis. Three pregnancies (0.8%) were terminated prior to viability and only two (0.5%) intrauterine deaths occurred, both due to placental abruption. Most women (81.5%) were delivered by caesarean section with fetal distress the most common reason for delivery. Neonatal intensive care was necessary in 40.7% of cases, with these babies staying a median of six days in intensive care. Conclusion Expectant management of early onset, severe pre-eclampsia and careful neonatal care led to high perinatal and neonatal survival rates. It also allowed the judicious use of neonatal intensive care facilities. Neonatal sepsis remains a cause for concern. [source]


    Is intensive care for very immature babies justified?

    ACTA PAEDIATRICA, Issue 2 2004
    M Levene
    Neonatal intensive care is generally considered justified in the majority of very premature infants, but there is some concern about the effectiveness of the techniques used at the margins of viability (22,24 wk of gestation). The controversy that exists in this area is largely due to a lack of agreed endpoints for geographically based populations where all live births are considered. Evaluation of outcome must also take the quality of neurological function in surviving infants into consideration, and in reviewing these data the reader is struck by the few reports providing information on a high proportion of survivors. To inform this debate, the "best data" for analysis are reviewed based on a number of criteria of quality for survival and outcome studies. Based on these data sets, >25% of babies born alive at 24 wk and below survive without major disability. Conclusion: An objective review of "best data" will provide the basis of an informed debate on whether providing intensive care for all very immature babies is appropriate in developed countries.

    Patterns of motor disability in very preterm children

    DEVELOPMENTAL DISABILITIES RESEARCH REVIEW, Issue 4 2002
    Melanie Bracewell
    Abstract Motor development in very preterm children differs in several important ways from that of children born at full term. Variability is common, although the anatomic and physiologic bases for that variability are often poorly understood. Motor patterns over the first postnatal year may depend on behaviours learned during often long periods of neonatal intensive care. The normal pattern of development may be modified by disturbances of brain function caused both by the interruption of normal brain maturation ex-utero and the superimposition of focal brain injuries following very preterm birth. Abnormal patterns of development over the first year may evolve into clear neuromotor patterns of cerebral palsy or resolve, as "transient dystonias." Cerebral palsy is associated with identified patterns of brain injury secondary to ischaemic or haemorrhagic lesions, perhaps modified by activation of inflammatory cytokines. Cerebral palsy rates have not fallen as might be expected over the past 10 years as survival has improved, perhaps because of increasing survival at low gestations, which is associated with the highest prevalence of cerebral palsy. Children who escape cerebral palsy are also at risk of motor impairments during the school years. The relationship of these impairments to perinatal factors or to neurological progress over the first postnatal year is debated. Neuromotor abnormalities are the most frequent of the "hidden disabilities" among ex-preterm children and are thus frequently associated with poorer cognitive ability and attention deficit disorders. Interventions to prevent cerebral palsy or to reduce these late disabilities in very preterm children are needed. MRDD Research Reviews 2002;8:241,248. © 2002 Wiley-Liss, Inc. [source]


    Community-based, Prospective, Controlled Study of Obstetric and Neonatal Outcome of 179 Pregnancies in Women with Epilepsy

    EPILEPSIA, Issue 1 2006
    Katriina Viinikainen
    Summary:,Purpose: This study evaluated obstetric and neonatal outcome in a community-based cohort of women with active epilepsy (WWAE) compared with the general pregnant population receiving modern obstetric care. Methods: We reviewed the total population who gave birth between January 1989 and October 2000 at Kuopio University Hospital. Obstetric, demographic, and epilepsy data were collected prospectively from 179 singleton pregnancies of women with epilepsy and from 24,778 singleton pregnancies of unaffected controls. The obstetric data from the pregnancy register was supplemented with detailed neurologic data retrieved from the medical records. The data retrieved were comprehensive because of a follow-up strategy according to a predecided protocol. Results: During pregnancy, the seizure frequency was unchanged, or the change was for the better in the majority (83%) of the patients. We found no significant differences between WWAE and controls in the incidence of preeclampsia, preterm labor, or in the rates of caesarean sections, perinatal mortality, or low birth weight. However, the rate of small-for-gestational-age infants was significantly higher, and the head circumference was significantly smaller in WWAE. Apgar score at 1 min was lower in children of WWAE, and the need for care in the neonatal ward and neonatal intensive care were increased as compared with controls. The frequency of major malformations was 4.8% (,0.6,10.2%; 95% confidence interval) in the 127 children of WWAE. Conclusions: Pregnancy course is uncomplicated and neonatal outcome is good in the majority of cases when a predecided protocol is used for the follow-up of WWAE in antenatal and neurologic care. Long-term follow-up of the neurologic and cognitive development of the children of WWAE is still needed. [source]


    Reducing nosocomial infection in neonatal intensive care: An intervention study

    INTERNATIONAL JOURNAL OF NURSING PRACTICE, Issue 6 2009
    Raijah Hj A Rahim MN RN SCM BScN
    Nosocomial infection is a common cause of morbidity and mortality for hospitalized neonates. This report describes measures taken to reduce the prevalence of nosocomial infection within a 34-bed neonatal intensive care unit in Malaysia. Interventions included a one-to-one education programme for nursing staff (n = 30); the education of cleaners and health-care assistants allocated to work in the unit; and the introduction of routine (weekly) screening procedure for all infants with feedback given to staff. The education programme for nurses focused on the application of standard precautions to three common clinical procedures: hand washing, tracheobronchial suctioning and nasogastric tube feeding. These were evaluated using competency checklists. The prevalence of nosocomial blood and respiratory tract infections declined over the 7-month study period. This study highlights the importance of education in contributing to the control of nosocomial infection in the neonatal intensive care unit. [source]


    Content Validation of Parental Role Conflict in the Neonatal Intensive Care Unit

    INTERNATIONAL JOURNAL OF NURSING TERMINOLOGIES AND CLASSIFICATION, Issue 1 2006
    Elenice Valentim Carmona MN
    PURPOSE.,To validate the content of the nursing diagnosis parental role conflict made by neonatal intensive care (NICU) nurses and researchers in the field and to identify the related major and minor defining characteristics. METHOD.,Fehring's Diagnostic Content Validation model using 59 neonatal specialists. FINDINGS.,Nineteen defining characteristics were validated for use in NICUs: four were considered major and 15 as minor. There was no correlation between nurse profiles and defining characteristic scores. CONCLUSIONS.,In this study, parental role conflict was validated for use in neonatal units but defining characteristics must be described in a clearer and more objective manner. NURSING IMPLICATIONS.,Validation studies in different healthcare settings are required so that the specificities of each clientele are met. NANDA diagnoses must be tested and validated at neonatal units, because this setting has developed few studies and their use in practice is a potential way to improve nursing care. [source]


    Neuroimaging of cortical development and brain connectivity in human newborns and animal models

    JOURNAL OF ANATOMY, Issue 4 2010
    Gregory A. Lodygensky
    Abstract Significant human brain growth occurs during the third trimester, with a doubling of whole brain volume and a fourfold increase of cortical gray matter volume. This is also the time period during which cortical folding and gyrification take place. Conditions such as intrauterine growth restriction, prematurity and cerebral white matter injury have been shown to affect brain growth including specific structures such as the hippocampus, with subsequent potentially permanent functional consequences. The use of 3D magnetic resonance imaging (MRI) and dedicated postprocessing tools to measure brain tissue volumes (cerebral cortical gray matter, white matter), surface and sulcation index can elucidate phenotypes associated with early behavior development. The use of diffusion tensor imaging can further help in assessing microstructural changes within the cerebral white matter and the establishment of brain connectivity. Finally, the use of functional MRI and resting-state functional MRI connectivity allows exploration of the impact of adverse conditions on functional brain connectivity in vivo. Results from studies using these methods have for the first time illustrated the structural impact of antenatal conditions and neonatal intensive care on the functional brain deficits observed after premature birth. In order to study the pathophysiology of these adverse conditions, MRI has also been used in conjunction with histology in animal models of injury in the immature brain. Understanding the histological substrate of brain injury seen on MRI provides new insights into the immature brain, mechanisms of injury and their imaging phenotype. [source]


    Relationships between nurse care-giving behaviours and preterm infant responses during bathing: a preliminary study

    JOURNAL OF CLINICAL NURSING, Issue 1-2 2010
    Jen-Jiuan Liaw
    Aims., The purpose of this study was to explore the relationships between specific nurse care-giving behaviours and preterm infant behavioural responses during bathing and to identify nurse behaviours associated with infant ,stress'. Background., Although recent advances in medical technology have improved neonatal intensive care, the high mortality and morbidity rates in preterm infants have not decreased proportionally. As caregivers strive to reduce infant mortality and morbidity, a factor for consideration is which caregiver behaviours are associated with preterm infant well-being. Design., A descriptive correlational design. Method., Convenience samples of 24 preterm infants and 12 nurses were recruited. A total of 120 baths were videotaped. Infant and nurse behaviours were measured using the coding schemes developed by the researchers. Pearson coefficient correlation, non-parametric Kruskal,Wallis test, t -test and generalised linear models were methods for data analysis. Results., As nurses provided more support, stress was reduced in the infants, and their self-regulation during the bath was enhanced especially by the use of ,containment' and ,positional support'. Conversely, non-therapeutic caregiver behaviours including ,rapid and rough handling' of the baby, ,chatting with other people' and ,inappropriate handling' increased infant ,stress' during the bath. Conclusion., The findings provide new information about the link between care-giving and infant responses and how caregivers can better interact with preterm infants during a very sensitive period of brain development. Relevance to clinical practice., How nurses take care of the preterm infants influences their responses to care-giving stimuli. To interact better with the infant during care-giving procedures, nurses need to provide more supportive care-giving behaviours especially ,position support' and ,containment' based on the infant's needs, and avoid care-giving that may be too rough and occur too quickly without attending the baby's stressful signals, positioning the baby in hyperextension posture, or chatting with other people during procedures.

    Evidenced-based clinical practice guideline for management of newborn pain

    JOURNAL OF PAEDIATRICS AND CHILD HEALTH, Issue 4 2010
    Kaye Spence
    Aim: To facilitate the uptake of evidence and to reduce the evidence practice gap for management of newborn pain through the development of a clinical practice guideline. Method: An audit of practice and an appraisal of clinical practice guidelines were undertaken to establish current practices and guideline availability for the management of newborn pain in 23 hospitals in Australia. Guidelines were appraised using the Appraisal of Guidelines for Research and Evaluation instrument. A literature search was undertaken to acquire the evidence for best practice for management of newborn pain. Results: Neonatal units in 17 hospitals had clinical practice guidelines. Each was peer reviewed and assessed according to the domains of the Appraisal of Guidelines for Research and Evaluation instrument. There was lack of consistency across the guidelines. As a result, a best practice guideline was developed based on current best evidence and the Royal Australian College of Physicians recommendations. To facilitate an ongoing compliance with the guideline, an audit tool was included together with algorithms for procedural pain and pain assessment. Conclusion: The clinical practice guideline can be used by clinicians in varying settings such as the neonatal intensive care and special care unit. The document can be used to support existing practices or challenge clinicians to close the evidence practice gap for the management of newborn pain. [source]


    Paediatric training for family doctors: principals and practice

    MEDICAL EDUCATION, Issue 5 2002
    C Melville
    Background There is controversy as to how best to train general practitioners for the paediatric challenges they will meet in practice, in particular what should be included in training, what should be left out and how long should it last? Subjects and methods All 615 general practice principals referring to 6 hospitals were surveyed (40% response rate). Setting West Midlands region of England. Study design Postal questionnaire. Statistics Quantitative and qualitative assessment of responses. Quantitative responses were analysed by hospital, decade of qualification, and duration of paediatric training. Qualitative responses were analysed using grounded theory. Results Satisfaction with training was directly related to its duration, with low levels of satisfaction for less than 6 months paediatrics, moderate levels for 6,11 months, and high levels with 12 months or more. The most important item of training was recognition of the sick child. Acute and chronic paediatrics was generally well covered. Psychosocial aspects, public health and immunisation were poorly addressed. Neonatal resuscitation and first day checks were seen as relevant, but neonatal intensive care was not. Conclusions At least 6 months of paediatrics is necessary for GPs in training, but longer paediatric exposure further increases their satisfaction with training. GPs have a biopsychosocial rather than biomedical approach to their child patients, suggesting potential benefits from a greater emphasis on psychosocial and public health aspects at the expense of neonatal intensive care. Recognition of the sick child is essential, and acute and chronic organic illness should be covered in breadth. Possible future models for GP training in paediatrics are discussed. [source]


    Use of premedication for intubation in tertiary neonatal units in the United Kingdom

    PEDIATRIC ANESTHESIA, Issue 7 2009
    RAJIV CHAUDHARY MBBS MRCPCH
    Summary Background:, Endotracheal intubation and laryngoscopy are frequently performed procedures in neonatal intensive care. These procedures represent profoundly painful stimuli and have been associated with laryngospasm, bronchospasm, hemodynamic changes, raised intracranial pressure and an increased risk of intracranial hemorrhage. These adverse changes can cause significant neonatal morbidity but may be attenuated by the use of suitable premedication. Aims:, To evaluate current practices for premedication use prior to elective intubation in UK tertiary neonatal units. Methods:, Telephone questionnaire survey of all 50 tertiary neonatal units in the UK. Results:, Ninety percent of units report the routine use of sedation prior to intubation and 82% of units routinely use a muscle relaxant. Morphine was the most commonly used sedative and suxamethonium was the most commonly used muscle relaxant. Approximately half of the units also used atropine during intubation. Seventy seven percent of units had a written policy for premedication. Ten percent of the units did not routinely use any sedatives or muscle relaxants for elective intubation. Conclusions:, In comparison with data from a 1998 survey, our study demonstrated an increase in the number of units that have adopted a written policy for premedication use, and in the number routinely using premedication drugs for elective intubation. There remains little consensus as to which drugs should be used and in what dose. [source]


    Meconium ileus,it is time to act now!

    PEDIATRIC PULMONOLOGY, Issue 10 2010
    Matthias Kappler MD
    Meconium ileus is a life-threatening presentation of neonates with cystic fibrosis (CF). Notwithstanding, today the long-term prognosis of such patients is comparable to that of CF patients not diagnosed in screening programs and not suffering from this insult,1,3 as confirmed by the article of Johnson et al. in this issue of Pediatric Pulmonology. Good news then for CF patients and CF caretakers, working with the modern interdisciplinary setting of neonatal intensive care, including radiology, anesthesiology, and pediatric surgery experts. State of the art management of life-threatening neonatal ileus during this fragile early phase of life obviously balances all disadvantages associated with neonatal ileus and provides an outcome not different from that in CF patients without meconium ileus, but diagnosed later during early childhood.

    Lung function and exhaled nitric oxide levels in infants developing chronic lung disease

    PEDIATRIC PULMONOLOGY, Issue 2 2007
    Olivia Williams MRCPCH
    Abstract Chronic lung disease (CLD) is a common outcome of neonatal intensive care. To determine whether the results of serial exhaled nitric oxide (eNO) measurements during the perinatal period differed between infants who did and did not develop CLD. In addition, we wished to assess whether eNO results were more predictive of CLD development than lung function test results or readily available clinical data (gestational age and birthweight). The patients were 24 infants with a median gestational age of 27 (range 25,31) weeks. Measurements of eNO levels, functional residual capacity (FRC), and compliance of the respiratory system (CRS) were attempted on postnatal days 1, 3, 5, 7, 14, and 28 days. The 12 infants who developed CLD were of significantly lower birthweight and gestational age than the rest of the cohort; in addition, they had lower median FRC (P,<,0.02) and CRS (P,<,0.02) results, but not higher eNO levels, in the first week after birth. Construction of receiver operator characteristic (ROC) curves demonstrated that the CRS and FRC results on Day 3 were the best predictors of CLD development; the areas under the ROC curves were 0.94 and 0.91, respectively. Early lung function test results, but not eNO levels, are useful in predicting CLD development, but are not significantly better than birthweight.

    Significance of hypocarbia in the development of periventricular leukomalacia in preterm infants

    PEDIATRICS INTERNATIONAL, Issue 3 2004
    Christina Giannakopoulou
    AbstractBackground:,Despite rapid advances in the management of preterm infants, periventricular leukomalacia (PVL) remains a considerable problem in neonatal intensive care. The aim of this study was to determine whether hypocarbia is associated with the development of PVL in mechanically ventilated, preterm infants and to emphasize the importance of avoiding this disturbance. Methods:,The authors evaluated 52 mechanically ventilated infants with a gestational age of <34 weeks, who exhibited hypocarbia in the first three postnatal days (lowest carbon dioxide tension being <25 mmHg). These infants were then compared with 52 infants in a control group not exhibiting hypocarbia, matched for birthweight and gestational age. A diagnosis of PVL was made on the basis of the results of cranial ultrasonography. Confounding factors potentially associated with the development of PVL were controlled in logistic regression analyses. Results:,Of the 52 mechanically ventilated preterm infants with hypocarbia, 10 (19.2%) developed cystic PVL, and six (11.5%) developed periventricular echodensity. Of the 52 infants in the control group only two (3.8%) developed cystic PVL, and one (1.9%) infant developed periventricular echodensity. The authors observed no significant differences in other prenatal and perinatal risk factors between the two groups. Conclusion:,Hypocarbia in mechanically ventilated preterm infants during the first days of life is suggested as being an independent predictor of PVL, predisposing these infants to subsequent neurodevelopmental delay.

    When a graph is poorer than 100 words: A comparison of computerised natural language generation, human generated descriptions and graphical displays in neonatal intensive care

    APPLIED COGNITIVE PSYCHOLOGY, Issue 1 2010
    Marian van der Meulen
    Volunteer staff from a Neonatal Intensive Care Unit (NICU) were presented with sets of anonymised physiological data recorded over approximately 45,minute periods from former patients. Staff were asked to select medical/nursing actions appropriate for each of the patients whose data were displayed. Data were shown in one of three conditions (a) as multiple line graphs similar to those commonly shown on the ward, or as textual descriptions generated by (b) expert medical/nursing staff or (c) computerised natural language generation (NLG). An overall advantage was found for the human generated text, but NLG resulted in decisions that were at least as good as those for the graphical displays with which staff were familiar. It is suggested that NLG might offer a viable automated approach to removing noise and artefacts in real, complex and dynamic data sets, thereby reducing visual complexity and mental workload, and enhancing decision-making particularly for inexperienced staff.

    Update on risk factors and future perspectives for preterm infants

    ACTA OPHTHALMOLOGICA, Issue 2009
    A HELLSTRöM
    Purpose To give an update on risk factors for retinopathy of prematurity with special focus on postnatal growth and growth factors Methods The relationship between birth weight, serum levels of IGF-I as well as postnatal longitudinal growth and ROP will be presented. Preventive measures will be discussed. Results Birth weight data on 451 infants demonstrated initially a significant difference in BW between different ROP stages but when taking gestational age and sex into account the significance was eliminated. Recently, a new diagnostic tool based on weekly neonatal measurements of body weight and serum insulin-like growth factor 1 (IGF-I) levels, was shown to be predictive for ROP development. The algorithm "Weight IGF-I Neonatal ROP" (WINROPÔ) predicted early (mean 10 weeks) all infants who later developed proliferative ROP requiring treatment. The WINROP algorithm was then taken one step further using only serial weight measurements (n=700), excluding blood sampling for measuring IGF-I. With this approach WINROP predicted all infants who later developed proliferative ROP requiring treatment (100% sensitivity) and correctly identified 75% of those who did not develop proliferative ROP, and thus would not need any ophthalmologic screening. We have also shown a close relationship between postnatal growth, severe ROP and poor brain development. Conclusion For decades, neonatal intensive care has focused on survival of the most immature babies. Time has come to find methods to ameliorate the nutrition for the children born very preterm. It is known that IGF-I is essential for growth and development of the immature vasculature of the eye. Intervention with substitution of IGF-I to the very preterm babies to raise IGF-I up to normal intrauterine levels might be beneficial. Commercial interest [source]


    Remifentanil in neonatal intensive care and anaesthesia practice

    ACTA PAEDIATRICA, Issue 10 2010
    Márcia Gomes Penido
    Abstract Remifentanil is a relatively new ultrashort action synthetic opioid. Studies on the use of remifentanil in neonatology have emerged demonstrating its effectiveness and safety in neonates. The present study describes the use of remifentanil in both full-term and premature newborns, highlighting the theoretical benefits for this population in terms of both neonatal intensive care and anaesthesia. A Medline search was undertaken of all reviews and reports about the use of remifentanil in neonates published between 1996 and 2009 using MeSH search terms ,remifentanil', ,analgesia', ,anaesthesia', ,newborn' and ,neonate'. The review points that remifentanil has been used with advantages in newborns including preterm neonates and even for foetal anaesthesia. It proved to be a good option to attenuate the hemodynamic/endocrine markers of stress related to surgery. Owing to its unique pharmacokinetic profile, shorter extubation times can be achieved what makes the drug also a good option for short duration invasive procedures in NICUs (InSurE). A concern on its use is that the hemodynamic response (hypotension) may become significant when the drug is associated to other drugs like sevoflurane. Conclusion:, Remifentanil seems to be an effective and safely used opioid for neonatal intensive care and anaesthesia practice. [source]


    Incidence of and risk factors for neonatal morbidity after active perinatal care: extremely preterm infants study in Sweden (EXPRESS)

    ACTA PAEDIATRICA, Issue 7 2010
    The EXPRESS Group
    Abstract Aims:, The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods:, Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004,2007. Results:, Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage ,3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ventilation decreased the chances of survival without these morbidities. Maternal smoking and higher gestational duration were associated with lower risk of severe ROP, whereas PDA and poor growth increased this risk. Conclusion:, Half of the infants surviving extremely preterm birth suffered from severe neonatal morbidities. Studies on how to reduce these morbidities and on the long-term health of survivors are warranted. [source]


    Neonatal intensive care utilization and neonatal outcome of infants born to women aged 40 years and over in New Zealand

    ACTA PAEDIATRICA, Issue 2 2010
    M Battin
    Abstract Background:, Increased maternal age is associated with pregnancy complications and there are few data available on neonatal outcome and utilization of neonatal resources. Our first aim was to use national New Zealand data to determine if the outcomes following admission to NICU are different for infants born to women aged 40 years and over, compared with those born to women under 40 years of age. The second aim was to document trends in the requirement of neonatal intensive care in infants born to women aged 40 years and older. Method:, Eligible infants were identified from registration with the Australian and New Zealand Neonatal Network for 1995,2004 inclusive. The relationship between maternal age and neonatal outcome was tested using univariate and multivariate analysis, and trends in the number of infants in maternal age groups below 35 years, 35,39 years and over 40 years were determined. Results:, On multivariate analysis using logistic regression, maternal age over 40 years was not found to be associated with a significant increase in the odds ratio for the composite poor outcome. However, over the 10-year period, there was an increase in the number of admissions and the percentage of admissions of infants born to women over 40 years of age. Conclusion:, Although the number of infants admitted for neonatal care following birth to women over 40 years of age has increased, these infants do not appear to have an increased risk of severe abnormal outcome.

    Clinician observation of physiological trend monitoring to identify late-onset sepsis in preterm infants

    ACTA PAEDIATRICA, Issue 9 2008
    Christopher J Dewhurst
    Abstract Aim: To determine whether trends in routinely collected physiological variables can be used retrospectively to classify infants according to the presence or absence of late-onset neonatal sepsis. Methods: Case control study. Thirty infants born ,32 weeks of gestation who developed late-onset sepsis were matched with 30 controls for gestational and postnatal age but remained sepsis free. For each infant, 25 clinicians inspected 48 h of routine monitoring of heart rate, respiratory rate and oxygen saturation. Clinicians were asked to determine whether the recording was obtained from an infant who did or did not develop sepsis and also indicate how confident they were in their judgement. Clinicians were stratified into three groups by professional role. Results: The median correct assignment of infant's recordings was 67% (IQR 62,72). When very confident, this improved to 82% (IQR 67,88). Overall sensitivity was 53% (IQR 43,63) and specificity 80% (IQR 67,87). Advanced neonatal nurse practitioners consistently assigned babies to the correct group more often than other professional groups. Conclusion: The simple observation physiological trend graphs can classify infants according to the presence or absence of late-onset neonatal sepsis. The accuracy of this method is good to strong but varies with experience of neonatal intensive care. [source]


    Cognitive function at 10 years of age in children who have required neonatal intensive care

    ACTA PAEDIATRICA, Issue 12 2004
    L Schermann
    Aim: To study cognitive function at 10 y of age in a cohort of children who required neonatal intensive care within the Uppsala Neonatal Follow-up Study. Methods: 226 children, who were born in 1986,1989 and had required neonatal intensive care (NIC) and 72 full-term, healthy control children were enrolled in the study. NIC children were grouped according to gestational age (group I, 23,31 wk; subgroup IA, 23,27 wk; IB 28,31 wk; group II, 32,36 wk; group III, >36wk), with infants with congenital malformation (IWCM) included and excluded from the main groups. The Kaufman Assessment Battery for Children (K-ABC) was administered and results were analysed in relation to the K-ABC global scales: sequential, simultaneous, mental processing composite and achievement. Results: The great majority of children had well-developed cognitive function, reaching scores at an average level or above. When groups were compared, full-term children that required NIC (group III) showed lower scores than controls on all scales measured by the K-ABC. Preterm children from all the studied groups (groups IA, IB, II) showed poorer performance than controls in the simultaneous processing scale, and group IA scored lower than controls in the achievement scale. The incidence of major cognitive impairment (IQ <70) was low in NIC children (<5%), but children from group IA showed significant higher frequency of impairment in the simultaneous, mental processing composite and achievement scales. Children from group IA presented a high frequency of discrepancy between the K-ABC scales, with lower simultaneous and higher sequential scores. Analysis with IWCM excluded from the main groups revealed identical results. Conclusion: Most children who needed neonatal intensive care had developed well their cognitive function at 10 y of age. The long-term effect of neonatal intensive care on cognitive function was more evident in extremely preterm infants (group IA), especially in tasks involving simultaneous ways of processing information.

    Rehospitalization of very preterm infants

    ACTA PAEDIATRICA, Issue 10 2004
    LAA Kollée
    Rehospitalization rates of very preterm infants because of reasons that are related to neonatal morbidity states can be decreased with further improvement of neonatal intensive care provided. Conclusion: Analysis of rehospitalization data should be included in follow-up programmes as a contribution to the development of strategies to improve neonatal care and the ultimate outcome for very-low-birthweight infants.

    Effects of neonatal intensive care on girls' and boys' language development

    ACTA PAEDIATRICA, Issue 3 2003
    F Lacerda
    According to Jennische and Sedin, very premature boys are less affected in their speech and language development than a matched group of girls. This is discussed from a general linguistic perspective. Conclusion: It is speculated that perinatal factors, timing and ambient aspects may impact on boys' advantage over girls. [source]

    Comparison of EML 105 and Advantage analysers measuring capillary versus venous whole blood glucose in neonates

    ACTA PAEDIATRICA, Issue 9 2001

    Aim: Near-patient blood glucose monitoring is an essential component of neonatal intensive care but the analysers currently used are unreliable and inaccurate. The aim of this study was to compare a new glucose electrode-based analyser (EML 105) and a non-wipe reflectance photometry method (Advantage) as opposed to a recognized laboratory reference method (Hexokinase). We also investigated the effect of sample route and haematocrit on the accuracy of the glucose readings obtained by each method of analysis. Methods: Whole blood glucose concentrations ranging from 0 to 3.5mmol/l were carefully prepared in a laboratory setting and blood samples from each respective solution were then measured by EML 105 and Advantage analysers. The results obtained were then compared with the corresponding plasma glucose reading obtained by the Hexokinase method, using linear regression analysis. An in vivo study was subsequently performed on 103 neonates, over a 1-y period, using capillary and venous whole blood samples. Whole blood glucose concentration was estimated from each sample using both analysers and compared with the corresponding plasma glucose concentration estimated by the Hexokinase method. Venous blood was centrifuged and haematocrit was estimated using standardized curves. The effect of haematocrit on the agreement between whole blood and plasma glucose was investigated, estimating the degree of correlation on a scatterplot of the results and linear regression analysis. Results: Both the EML 105 and Hexokinase methods were highly accurate, in vitro, with small proportional biases of 2% and 5%, respectively. However, in vivo, both study analysers overestimated neonatal plasma glucose, ranging from at best 0.45 mmol/l (EML 105 venous) to 0.69 mmol/l (EML capillary). There was no significant difference in the agreement of capillary (GD = 0.12, 95% CI. {-0.32,0.08}, p= 0.2) or venous samples (GD = 0.05, 95% CI. {0.09, 0.19}, p= 0.49) with plasma glucose when analysed by either study method (GD = glucose difference between study analyser and reference method) However, the venous samples analysed by EML 105 estimated plasma glucose significantly better than capillary samples using the same method of analysis (GD = 0.24, 95% CI. {0.09, 0.38}, p < 0.01). The relationship between haematocrit and the resultant glucose differences was non-linear with correlation coefficients of r= -0.057 (EML 105 capillary), r= 0.145 (EML 105 venous), r= -0.127 (Advantage capillary) and r= -0.275 (Advantage venous). There was no significant difference in the effect of haematocrit on the performance of EML 105 versus Advantage, regardless of the sample route. Conclusion: Both EML 105 and Advantage overestimated plasma glucose, with no significant difference in the performance of either analyser, regardless of the route of analysis. Agreement with plasma glucose was better for venous samples but this was only statistically significant when EML 105 capillary and venous results were compared. Haematocrit is not a significant confounding factor towards the performance of either EML 105 or Advantage in neonates, regardless of the route of sampling. The margin of overestimation of blood glucose prohibits the recommendation of both EML 105 and Advantage for routine neonatal glucose screening. The consequences include failure accurately to diagnose hypoglycaemia and delays in the instigation of therapeutic measures, both of which may potentially result in an adverse, long-term, neurodevelopmental outcome.
