Short term outcome in babies refused perinatal intensive care.

OBJECTIVE--To compare the mortality in babies refused admission to a regional perinatal centre with that in babies accepted for intensive care in the centre. DESIGN--Retrospective study with group comparison. SETTING--Based at the Royal Maternity Hospital, Belfast, with follow up of patients in all obstetric units in Northern Ireland. PATIENTS--Requests for transfer of 675 babies to the regional perinatal centre (prenatally and postnatally) were made from hospitals in Northern Ireland between January 1984 and December 1986. In all, 343 babies were refused admission to the centre, and complete data were available for 332 of them. These babies were either admitted to other neonatal intensive care units (261 babies) or remained in hospitals with only special care cots (71 babies). MAIN OUTCOME MEASURE--Short term mortality. RESULTS--Seventy of the 332 babies refused admission to the centre died compared with 51 of the 333 who were admitted. Multivariate analysis based on a logistic model showed a non-significant increase in mortality among babies treated in other intensive care units compared with babies treated in the centre (relative odds 1.2; 95% confidence interval 0.7 to 1.9). The increase in mortality in babies who remained in a special care baby unit, however, was significant (3.5; 1.7 to 7.0). This increase was particularly significant in babies born at less than or equal to 32 weeks'' gestation and who weighed less than 1500 g (8.4; 2.5 to 28.1). CONCLUSIONS--The results of the study confirm the benefits of neonatal intensive care and its particular value in improving survival in babies of low birth weight. As the babies were refused admission to the regional perinatal centre because intensive care cots were not available this deficiency should be corrected.     

Intensive Care Society's APACHE II study in Britain and Ireland--II: Outcome comparisons of intensive care units after adjustment for case mix by the American APACHE II method.

OBJECTIVES--To compare outcome between intensive care units in Britain and Ireland both before and after adjustment for case mix with the American APACHE II method and to validate the American APACHE II method in Britain and Ireland. DESIGN--Prospective, cohort study of consecutive admissions to intensive care units. SETTING--26 general intensive care units in Britain and Ireland. SUBJECTS--8796 admissions to the study intensive care units. MAIN OUTCOME MEASURE--Death or survival at discharge from intensive care unit and hospital. RESULTS--At discharge from both intensive care unit and hospital there was a greater than twofold variation in crude mortality between the 26 units. After adjustment for case mix, variations in mortality were still apparent. For four intensive care units the observed numbers of deaths were significantly different from the number predicted by the American APACHE II equation. The overall goodness of fit, or predictive ability, of the APACHE II equation for the British and Irish data was good, being only slightly inferior to that obtained when the equation was tested on the data from which it had been derived. When patients were grouped by various factors such as age and diagnosis, the equation did not adjust across the subgroups in a uniform manner. CONCLUSIONS--The American APACHE II equation did not fit the British and Irish data. Use of the American equation could be of advantage or disadvantage to individual intensive care units, depending on the mix of patients treated.     

Arrangements for special and intensive care of the newborn.

All the special care baby units in three Thames health regions completed a one-day census on the number of infants in the unit, staffing, and facilities. The results were assessed in the light of the recommendations of an expert group set up by the Department of Health and Social Security. Although the provision of cots (6.1-6.9 per 1000 live births) was more generous than the estimated need and the occupancy rate (59--63%) lower than suggested, some units did not have adequate trained nursing cover at night, some did not have resident paediatricians, and some lacked essential equipment. Some small units, on the other hand, had very expensive equipment that was probably underused. Relating this provision to the regional statistics on babies needing special care showed that there was room for the rationalisation of facilities for their care. Factors that should be considered in planning such care include the size of the child-bearing population, the percentage of infants of low birth weights, and the proximity of specialist paediatric and maternity units and pathology facilities. It is also essential to monitor the effectiveness of the care by assessing the outcome in babies admitted to special units, especially those of low birth weight.     

Intensive Care Society's APACHE II study in Britain and Ireland--I: Variations in case mix of adult admissions to general intensive care units and impact on outcome.

OBJECTIVES--To describe the extent of variation in the case mix of adult admissions to general intensive care units in Britain and Ireland and investigate the impact of such variation on outcome. DESIGN--Prospective, cohort study of consecutive admissions to intensive care units. SETTING--26 general intensive care units in Britain and Ireland. SUBJECTS--9099 admissions to the intensive care units studied. MAIN OUTCOME MEASURE--Death or survival at discharge before and after adjustment of case mix (age, history of chronic conditions, surgical status, diagnosis, and severity of illness) according to the APACHE II method. RESULTS--Important differences in case mix were found, with large variations between the units. Hospital mortality was significantly associated with most of the case mix factors investigated. CONCLUSIONS--Comparing crude death rates in hospital between intensive care units may be misleading indicators of performance. The collection of data on case mix needs to be standardised and differences in case mix adjusted for when comparing outcome between different intensive care units.     

Preterm EEG: A Multimodal Neurophysiological Protocol

Since its introduction in early 1950s, electroencephalography (EEG) has been widely used in the neonatal intensive care units (NICU) for assessment and monitoring of brain function in preterm and term babies. Most common indications are the diagnosis of epileptic seizures, assessment of brain maturity, and recovery from hypoxic-ischemic events. EEG recording techniques and the understanding of neonatal EEG signals have dramatically improved, but these advances have been slow to penetrate through the clinical traditions. The aim of this presentation is to bring theory and practice of advanced EEG recording available for neonatal units. In the theoretical part, we will present animations to illustrate how a preterm brain gives rise to spontaneous and evoked EEG activities, both of which are unique to this developmental phase, as well as crucial for a proper brain maturation. Recent animal work has shown that the structural brain development is clearly reflected in early EEG activity. Most important structures in this regard are the growing long range connections and the transient cortical structure, subplate. Sensory stimuli in a preterm baby will generate responses that are seen at a single trial level, and they have underpinnings in the subplate-cortex interaction. This brings neonatal EEG readily into a multimodal study, where EEG is not only recording cortical function, but it also tests subplate function via different sensory modalities. Finally, introduction of clinically suitable dense array EEG caps, as well as amplifiers capable of recording low frequencies, have disclosed multitude of brain activities that have as yet been overlooked.In the practical part of this video, we show how a multimodal, dense array EEG study is performed in neonatal intensive care unit from a preterm baby in the incubator. The video demonstrates preparation of the baby and incubator, application of the EEG cap, and performance of the sensory stimulations.     

Fragile lives with fragile rights: Justice for babies born at the limit of viability

There is an inconsistency in the ways that doctors make clinical decisions regarding the treatment of babies born extremely prematurely. Many experts now recommend that clinical decisions about the treatment of such babies be individualized and consider many different factors. Nevertheless, many policies and practices throughout Europe and North America still appear to base decisions on gestational age alone or on gestational age as the primary factor that determines whether doctors recommend or even offer life‐sustaining neonatal intensive care treatment. These policies are well intentioned. They aim to guide doctors and parents to make decisions that are best for the baby. That is an ethically appropriate goal. But in relying so heavily on gestational age, such policies may actually do the babies a disservice by denying some babies treatment that might be beneficial and lead to intact survival. In this paper, we argue that such policies are unjust to premature babies and ought to be abolished. In their place, we propose individualized treatment decisions for premature babies. This would treat premature babies as we treat all other patients, with clinical decisions based on an individualized estimation of likelihood that treatment would be beneficial.     

Family centred care for the neonate -- the view from Wolverhampton

The increased technology of neonatal intensive care has meant that babies born at increasingly lower gestational age are surviving to be discharged home. A family centred approach in neonatal care supports the move toward patient or parent empowerment, which is vital, if babies are to be fully integrated into the family unit. Nurses are essential to the success of this process as they have the most direct and prolonged contact with both family and their baby. Critical care areas such as Neonatal Units (NNU) can be adjusted to support a more family focused philosophy. In Wolverhampton Orems 'Self-Care Model' of self care has been adapted to the family as the self care unit and simple adjustments to the area such as Quiet Times supports families feeling of well being and control.     

Outbreak of Gastroenteritis due to Salmonella virchow in a Maternity Hospital

An outbreak of gastroenteritis due to Salmonella virchow occurred in a maternity hospital in the Midlands in October–November 1968. Twenty-six babies and six mothers were infected. Fifteen of the babies had diarrhoea and 10 of these were in the special care baby unit The only fatal case was that of an infant with gross congenital malformations.The outbreak followed the admission of a patient to the delivery suite who was subsequently shown to be a symptomless excreter of S. virchow. A major factor in the spread of this organism is thought to have been heavy environmental contamination resulting from diarrhoea due to infection of her newborn baby.     

Surgical audit: Comparison of the work load and results of two hospitals in the same district.

Surgical audit is being undertaken to monitor and compare (by computer) the type of patient, work load, and results of two similar surgical units. Both units are in the City and Hackney District of London, one at St Bartholomew''s Hospital and the other at Hackney Hospital. During 1978, 736 patients were admitted by the unit at St Bartholomew''s Hospital and 902 by the unit at Hackney. At St Bartholomew''s 70% of admissions were elective compared with 49% at Hackney, where 86% of patients lived within the district compared with only 36% at St Bartholomew''s. The wound was the commonest site for complications, infection affecting 9% of those at Hackney and 6% at St Bartholomew''s, despite identical antibiotic policies. There were six post-operative deaths at St Bartholomew''s and 32 at Hackney. In both hospitals the length of stay was similar, 50% of patients being discharged within one week and 80% within two weeks. As a result of the audit a vigorous venous thrombosis prophylactic regimen has been instituted, and at Hackney the anaesthetic department has been strengthened and a new intensive care unit opened.     

Infection with netilmicin resistant Serratia marcescens in a special care baby unit.

An outbreak of colonisation and infection with a netilmicin resistant strain of Serratia marcescens occurred in a special care baby unit. S marcescens was isolated from a total of 13 babies; significant infection occurred in five, of whom two died. Epidemiological investigation failed to detect a common source but gastrointestinal colonisation of babies formed a prolonged and possibly important reservoir for infection. Containment proved difficult until the unit was closed to new admissions, and even then spread to a temporary unit ensued. O Serotyping and bacteriophage typing disclosed a single epidemic strain. This produced an aminoglycoside acetylating enzyme (AAC(6'')) conferring resistance to netilmicin and tobramycin and moderate resistance to amikacin. Use of gentamicin resulted in the isolation of serratia with increased resistance to all aminoglycosides, and, similarly, increased resistance to third generation cephalosporins emerged with their use.     

Should we abandon Kielland's forceps?

To assess the risks associated with the use of Kielland''s forceps 2708 consecutive deliveries were studied prospectively and the neonatal outcome related to the mode of delivery. Of the 1191 primigravidas, 279 (23.4%) underwent instrumental delivery, of whom 65 (5.5%) were delivered with Kielland''s forceps. There was no difference in early neonatal outcome (as judged by Apgar scores, intubations, and admission to the special care baby unit) between these babies and those delivered normally or by non-rotational forceps, but a higher proportion of the 127 (10.7%) delivered by emergency caesarean section were compromised. Of the 1517 multigravid patients, only 57 (3.8%) underwent instrumental delivery, 15 (1.0%) by Kielland''s forceps. Among these babies, also, the outcome was no worse than for those delivered normally, but the babies delivered by caesarean section showed a greatly increased incidence of low Apgar scores, intubations, and admission to the special care baby unit. There were no stillbirths or neonatal deaths among babies delivered by Kielland''s forceps, nor were there any cases of severe birth trauma or of obvious neonatal morbidity.     

Survey of intensive care of severely head injured patients in the United Kingdom.

OBJECTIVES--To study practice in intensive care of patients with severe head injury in neurosurgical referral centres in United Kingdom. DESIGN--Structured telephone interview of senior nursing staff in intensive care unit of adult neurosurgical referral centre. SETTING--39 intensive care units in hospitals that accepted acute head injuries for specialist neurosurgical management, identified from Medical Directory and information from professional bodies. MAIN OUTCOME MEASURES--Details of organisation and administration of intensive care and patterns of monitoring and treatment for patients admitted with severe head injury. RESULTS--Patients were managed in specialist neurosurgical intensive care units in 21 of the centres and in general intensive care units in 18. Their intensive care was coordinated by an anaesthetist in 25 units and by a neurosurgeon in 12. Annual case-load varied between units: 20 received > 100 patients, 12 received 50-100, and seven received 25-49. Monitoring and treatment varied considerably between centres. Invasive arterial pressure monitoring was used routinely in 36 units, but central venous pressure monitoring was routinely used in 24 and intracranial pressure was routinely monitored in only 19. Corticosteroids were used to treat intracranial hypertension in 19 units. Seventeen units routinely aimed for arterial carbon dioxide pressure of 3.3-4.0 kPa, and one unit still used severe hyperventilation to a pressure of < 3.3 kPa. CONCLUSION--The intensive care of patients with acute head injuries varied widely between the centres surveyed. Rationalisation of the intensive care of severe head injury with the production of widely accepted guidelines ought to improve the quality of care.     

‘Agonistic buffering’ in the wild barbary macaque,Macaca sylvana L.

Barbary apes are known to exhibit male care of babies at various locations, but only in the Middle Atlas mountains of Morocco has it been reported that a baby may be used in male-male interactions, apparently reducing the likelihood of aggression. The present study was made in order to discover if the behavior was characteristic of other groups reproductively isolated from the Atlas population. Male-male interactions involving a baby were observed in two groups and are described in detail; their friendly nature supports the hypothesis that the presence of a baby reduces the likelihood of aggression. We did not, however, see the active use of babies in this context which has been described for the Atlas population.     

Babies with spina bifida treated without surgery: parents' views on home versus hospital care.

From 1971 to 1981, 98 babies born with meningomyelocoele at the North Staffordshire Hospital Centre''s district maternity hospital, were thought not suitable for surgery. Sixty three survived for more than one week. Over the period the hospital''s policy changed: initially all such babies were kept in hospital, but later parents were given the choice of taking their baby home for palliative and terminal care. In an attempt to determine parents'' views on the care of their baby the parents of 44 of the babies who survived to one week were traced in 1985-6, five to 14 years later; 80 of them were asked how they felt about the lives and deaths of their babies. Eighteen babies had been taken home, and they had lived longer than the 26 who had been cared for in hospital. Parents whose baby had remained in hospital were sadder than those who had taken their baby home when they looked back at their experiences, and they also considered that their baby''s life had been of poor quality. Most of those who had taken their baby home had a more positive view of their child''s life. The figures suggest that the bereavement process after a baby''s death is longer than has been thought, but despite residual sadness just over half of the parents interviewed thought that something positive had come out of their experience.     

Uptake,Outcomes, and Costs of Antenatal,Well-Baby,and Prevention of Mother-to-Child Transmission of HIV Services under Routine Care Conditions in Zambia

Background

Zambia adopted Option A for prevention of mother-to-child transmission of HIV (PMTCT) in 2010 and announced a move to Option B+ in 2013. We evaluated the uptake, outcomes, and costs of antenatal, well-baby, and PMTCT services under routine care conditions in Zambia after the adoption of Option A.

Methods

We enrolled 99 HIV-infected/HIV-exposed (index) mother/baby pairs with a first antenatal visit in April-September 2011 at four study sites and 99 HIV-uninfected/HIV-unexposed (comparison) mother/baby pairs matched on site, gestational age, and calendar month at first visit. Data on patient outcomes and resources utilized from the first antenatal visit through six months postpartum were extracted from site registers. Costs in 2011 USD were estimated from the provider’s perspective.

Results

Index mothers presented for antenatal care at a mean 23.6 weeks gestation; 55% were considered to have initiated triple-drug antiretroviral therapy (ART) based on information recorded in site registers. Six months postpartum, 62% of index and 30% of comparison mother/baby pairs were retained in care; 67% of index babies retained had an unknown HIV status. Comparison and index mother/baby pairs utilized fewer resources than under fully guideline-concordant care; index babies utilized more well-baby resources than comparison babies. The average cost per comparison pair retained in care six months postpartum was $52 for antenatal and well-baby services. The average cost per index pair retained was $88 for antenatal, well-baby, and PMTCT services and increased to $185 when costs of triple-drug ART services were included.

Conclusions

HIV-infected mothers present to care late in pregnancy and many are lost to follow up by six months postpartum. HIV-exposed babies are more likely to remain in care and receive non-HIV, well-baby care than HIV-unexposed babies. Improving retention in care, guideline concordance, and moving to Option B+ will result in increased service delivery costs in the short term.     

A randomised controlled trial comparing two schedules of antenatal visits: the antenatal care project.

OBJECTIVE--To compare the clinical and psychological effectiveness of the traditional British antenatal visit schedule (traditional care) with a reduced schedule of visits (new style care) for low risk women, together with maternal and professional satisfaction with care. DESIGN--Randomised controlled trial. SETTING--Places in south east London providing antenatal care for women receiving shared care and planning to deliver in one of three hospitals or at home. SUBJECT--2794 women at low risk fulfilling the trial''s inclusion criteria between June 1993 and July 1994. MAIN OUTCOME MEASURES--Measures of fetal and maternal morbidity, health service use, psychosocial outcomes, and maternal and professional satisfaction. RESULTS--Pregnant women allocated to new style care had fewer day admissions (0.8 v 1.0; P=0.002) and ultrasound scans (1.6 v 1.7; P=0.003) and were less often suspected of carrying fetuses that were small for gestational age (odds ratio 0.73; 95% confidence interval 0.54 to 0.99). They also had some poorer psychosocial outcomes; for example, they were more worried about fetal wellbeing antenatally and coping with the baby postnatally, and they had more negative attitudes to their babies, both in pregnancy and postnatally. These women were also more dissatisfied with the number of visits they received (odds ratio 2.50; 2.00 to 3.11). CONCLUSIONS--Patterns of antenatal care involving fewer routine visits for women at low risk may lead to reduced psychosocial effectiveness and dissatisfaction with frequency of visits. The number of antenatal day admissions and ultrasound scans performed may also be reduced. For the variables reported, the visit schedules studied are similar in their clinical effectiveness. Uncertainty remains as to the clinical effectiveness of reduced visit schedules for rare pregnancy problems.     

Nosocomial transmission of group B streptococci.

The acquisition of group B streptococci by babies in a special-care baby unit and two postnatal wards was investigated over a six-month period using serology and phage typing. Sixty-three culture-positive babies were identified in the postnatal wards, one-third of whom had been born to mothers who were not carrying the organism in the genital tract or anorectal area during labour. A non-maternal source was identified for 14 of these 21 infants: either colonised mothers and babies in the same ward or, on one occasion, a member of the hospital staff. In the special-care baby unit, however, only one instance of nosocomial acquisition of group B streptococci was recorded despite a high prevalence of colonisation in the staff on the unit and the presence of heavily colonised babies. The results of this survey suggest that although sepsis caused by group B streptococci may be the result of nosocomial transmission, this may be prevented by careful attention to hygiene.     

Outcome of breech delivery at term.

OBJECTIVE--To compare neonatal mortality and morbidity in term infants presenting by the breech and delivered vaginally or by caesarean section. DESIGN--Population based comparison of outcomes. Data derived from the St Mary''s maternity information system. SETTING--North West Thames Regional Health Authority, 1988-90. SUBJECTS--3447 singleton fetuses presenting by the breech at term. MAIN OUTCOME MEASURES--Intrapartum and neonatal mortality, low Apgar scores, intubation at birth, and admission to special care baby units. RESULTS--After the exclusion of babies with congenital anomalies the incidence of intrapartum and neonatal death associated with vaginal birth was 8/961 (0.83%) compared with 1/2486 (0.03%) in babies born by caesarean section (relative risk 20, 95% confidence interval 2.5 to 163). The numbers of low Apgar scores and neonatal intubation were doubled in babies born vaginally or by emergency caesarean section compared with those delivered by elective operation. CONCLUSIONS--The good neonatal outcome associated with elective caesarean delivery of the term breech fetus may influence the decision of women and their obstetricians about mode of delivery.     

Development of bacterial and bifidobacterial communities in feces of newborn babies

Microbial 16S rDNA from babies' fecal samples were amplified by PCR, and analysed by denaturing gradient gel electrophoresis (DGGE), cloning and sequencing. PCR-DGGE profiles were used to follow in time the colonization of the intestine by bacteria. Four healthy babies, one baby who received antibiotics and their parents participated to the present study to determine the extent to which administration of antibiotics can modify the bacterial colonization of neonatal human gut and verify the influence of parental factors on the formation of the fecal bacterial community. In the healthy babies, Escherichia coli or bacteria belonging to Clostridium spp. were the initial colonizers rapidly followed by Bifidobacterium, Bacteroides, Clostridium, Streptococcus, Enterococcus and Actinomyces. Bifidobacterium species appeared already after five days in the breast-fed babies while there was a delay in the baby who received a formula based diet during only one day after birth. In each baby two or three bifidobacterial species including B. infantis were found. The observed variations in species were not associated with the feeding changes. The comparison of DGGE profiles of the babies and their parents patterns showed bands with equal migration suggesting a vertical transmission determined by genetic and environmental factors. The brief appearance of pioneer bacteria determined as being E. coli and Enterococcus spp. in the profile from the baby under antibiotic therapy, was succeeded by a small stable community consisting of Ruminococcus species. No Bifidobacterium sequences were detectable in this antibiotic-treated baby in spite of a partly breast-milk diet.     

Baby Stealing

Analysis of 13 cases of baby stealing by women distinguished four groups of cases. (1) Girls of subnormal intelligence, who stole a baby to play with. (2) Schizophrenic patients, whose offence was motivated by delusional ideas. (3) Psychopathic personalities, characterized by a previous history of delinquency, hysterical personality traits, and a preoccupation with their desire to have children. Their baby stealing seemed motivated by an attempt to compensate for their emotional deprivation, and they usually stole children whom they had previously helped to care for. (4) A “manipulative” group with a milder degree of personality disorder, in whom the motive for baby stealing was an attempt to influence a man by whom they had become pregnant and with whom their relationship was insecure. The offence was precipitated by a crisis such as a miscarriage or the threat of desertion. These women presented the stolen baby to their partner pretending that the child was his.Baby stealing seems usually to be an attempt to compensate for emotional deprivation or frustrated maternal feelings, and a real or imaginary miscarriage may be a predisposing or precipitating factor. The offence rarely seems premediated, though there was evidence of previous planning in some cases, particularly in the manipulative group. The stolen babies were well cared for and were usually quickly recovered.
