Death of an infant is acutely stressful for parents and professionals. Little is known about junior nurses' experiences providing end-of-life care in Neonatal units (NNU). This study aimed to better understand junior nurses' experiences providing end-of-life care in NNU. Neonatal nurses (n = 12) with less than 3 years experience participated in a focus group. Nominal Group Technique (NGT) was used to build consensus around the challenges faced, alongside suggested developments in improving future care provision. Primary analysis involved successive rounds of ranking and decision-making whilst secondary analysis involved thematic analysis. All issues, whether environmental, professional or social appeared driven by an awareness on the part of nurses, that there was no ‘second chance’ which created a huge pressure to ‘get if right’ for the infants and families. Regarding future care 2 areas of improvement identified were ‘Education and Training’ and Support. This paper unpacks these findings making recommendations for practice.

Accurate information and support from healthcare professionals as well as respect for parental choice are all factors which contribute to effective breastfeeding in the neonatal unit; with this in mind, Colm Darby and Sharon Nurse discuss the potential problems in expressing breast milk and the interventions which might be effective in avoiding them. Advocacy is an inherent part of neonatal nurses' role whilst caring for sick, vulnerable babies. Colm Darby is a male neonatal nurse working in a predominantly female environment and passionately believes in supporting and advocating for mothers who want to provide breast milk for their babies. In this article, CoIm uses Borton's model of reflection to discuss how he acted as an effective advocate for such a mother.

Background

An infant’s death is acutely stressful for parents and professionals. Little is known about junior nurses’ experiences providing end-of-life care in Neonatal Units (NNU).

Objectives

To better understand junior nurses’ experiences providing end-of-life care in NNU, the study explored the challenges and opportunities inherent in their practice relating to providing such care to babies and their families.

Methods

Neonatal nurses (n=12) with less than 3 years’ experience who were undergoing a neonatal education programme participated. Two focus groups were convened each with 6 nurses. The Ethics Committee at the relevant University approved the study. Nominal Group Technique (NGT) was used in the focus groups to build consensus around the challenges faced by junior nurses, alongside suggested developments in improving future care provision. Primary analysis involved successive rounds of ranking and decision making whilst secondary analysis involved thematic analysis.

Results

The study identified the pressures these nurses felt in having only one chance to ‘get it right’ for the infants and their families. They perceived the need for further ‘education and training’ highlighting that improved education provision would include both additional courses and internal training sessions. Greater ‘support’ from mentors themselves more experienced in this aspect of care within the NNU was identified as important in addressing issues around confidence building and skill development.

Conclusions

The results highlight junior nurses’ need for specific education and mentorship around end-of-life care for babies. This presentation will outline the implications for practice, education and further research.

BACKGROUND: Research shows evidence for the importance of physical and emotional closeness for the infant, the parent and the infant-parent dyad. Less is known about how, when and why parents experience emotional closeness to their infants in a neonatal unit (NU), which was the aim of this study. METHODS: A qualitative study using a salutogenic approach to focus on positive health and wellbeing was undertaken in three NUs: one in Sweden, England and Finland. An 'emotional closeness' form was devised, which asked parents to describe moments/situations when, how and why they had felt emotionally close to their infant. Data for 23 parents of preterm infants were analyzed using thematic networks analysis. RESULTS: A global theme of 'pathways for emotional closeness' emerged from the data set. This concept related to how emotional, physical, cognitive and social influences led to feelings of emotional closeness between parents and their infants. The five underpinning organising themes relate to the: Embodied recognition through the power of physical closeness; Reassurance of, and contributing to, infant wellness; Understanding the present and the past; Feeling engaged in the day to day and Spending time and bonding as a family. CONCLUSION: These findings generate important insights into why, how and when parents feel emotionally close. This knowledge contributes to an increased awareness of how to support parents of premature infants to form positive and loving relationships with their infants. Health care staff should create a climate where parents' emotions and their emotional journey are individually supported.

AIM: Studies have provided insights into factors that may facilitate or inhibit parent-infant closeness in neonatal units, but none have specifically focused on the perspectives of senior neonatal staff. The aim of this study was to explore perceptions and experiences of consultant neonatologists and senior nurses in five European countries with regard to these issues. METHODS: Six small group discussions and three one-to-one interviews were conducted with 16 consultant neonatologists and senior nurses representing nine neonatal units from Estonia, Finland, Norway, Spain and Sweden. The interviews explored facilitators and barriers to parent-infant closeness and implications for policy and practice and thematic analysis was undertaken. RESULTS: Participants highlighted how a humanising care agenda that enabled parent-infant closeness was an aspiration, but pointed out that neonatal units were at different stages in achieving this. The facilitators and barriers to physical closeness included socio-economic factors, cultural norms, the designs of neonatal units, resource issues, leadership, staff attitudes and practices and relationships between staff and parents. CONCLUSION: Various factors affected parent-infant closeness in neonatal units in European countries. There needs to be the political motivation, appropriate policy planning, legislation and resource allocation to increase measures that support closeness agendas in neonatal units.

Objective: Phenobarbital increases electroclinical uncoupling and our preliminary observations suggest it may also affect electrographic seizure morphology. This may alter the performance of a novel seizure detection algorithm (SDA) developed by our group. The objectives of this study were to compare the morphology of seizures before and after phenobarbital administration in neonates and to determine the effect of any changes on automated seizure detection rates. Methods: The EEGs of 18 term neonates with seizures both pre- and post-phenobarbital (524 seizures) administration were studied. Ten features of seizures were manually quantified and summary measures for each neonate were statistically compared between pre- and post-phenobarbital seizures. SDA seizure detection rates were also compared. Results: Post-phenobarbital seizures showed significantly lower amplitude (p < 0.001) and involved fewer EEG channels at the peak of seizure (p < 0.05). No other features or SDA detection rates showed a statistical difference. Conclusion: These findings show that phenobarbital reduces both the amplitude and propagation of seizures which may help to explain electroclinical uncoupling of seizures. The seizure detection rate of the algorithm was unaffected by these changes. Significance: The results suggest that users should not need to adjust the SDA sensitivity threshold after phenobarbital administration.

Na avaliação da exposição profissional a agentes químicos a monitorização do ar do ambiente de trabalho é a metodologia mais utilizada e o valor-limite mais frequentemente utilizado é a Concentração Média Ponderada. Recentemente alguns estudos têm sido realizados recorrendo a uma avaliação da exposição profissional baseada na atividade desenvolvida pelo trabalhador. O principal objectivo do estudo é demonstrar a importância da avaliação da exposição profissional ser realizada por actividade quando se pretende seleccionar as medidas de eliminação e/ou controlo da exposição mais adequadas e prioritárias. Pretendeu-se igualmente demonstrar a utilidade do conhecimento detalhado da actividade para definir a melhor estratégia de avaliação ambiental.

O ensaio cometa é um dos ensaios de avaliação de genotoxicidade mais promissores de avaliação do risco humano, sendo recomendado para a monitorização de populações com exposição crónica a agentes genotóxicos. Os laboratórios são ambientes profissionais em que os trabalhadores podem encontrar-se expostos a agentes químicos. As drogas antineoplásicas são agentes químicos que são considerados carcinogénicos e, desta forma, medidas de protecção especiais devem ser adoptadas. O objectivo desta comunicação é contribuir para o desenvolvimento de um programa de biomonitorização que inclui a avaliação de genotoxicidade relacionada com biomarcadores de susceptibilidade genética.

O presente estudo pretende avaliar a exposição ocupacional a contaminação fúngica e bacteriana em quartos de hotel, mais precisamente em dois quartos com características diferentes, nomeadamente, com pavimento em alcatifa e outro sem alcatifa. Doze amostras de ar de 250L foram colhidas pelo método de impacto, em meio agar de extracto de malte (MEA) suplementado com cloranfenicol (0,05%) para fungos e em meio de TSA (agar de soja tríptica) com nistatina (0,2%) para bactérias. Foram também realizadas amostras de superfície nos mesmos locais. Em ambos os quartos apenas uma amostra de ar, no quarto sem alcatifa, apresentou contagens de fungos mais elevadas do que no exterior. No entanto, as concentrações de bactérias no ar interior foram superiores às do ar exterior. Em relação às superfícies, o quarto sem alcatifa apresentou diferenças estatisticamente significativas em relação ao quarto com alcatifa, sendo que o primeiro apresentou concentrações mais elevadas de fungos. Todas as superfícies analisadas apresentaram contaminação bacteriana, mas não houve diferenças estatisticamente significativas entre os quartos. Os géneros de fungos mais prevalentes no ar foram idênticos em ambos os quartos (Penicillium sp. 40,7% - 12,3% e Cladosporium sp. 43,5% - 55,4%). Nas superfícies analisadas, os isolados pertencentes ao complexo Aspergillus fumigatus foram os únicos encontrados no quarto com alcatifa, enquanto no outro quarto os géneros mais prevalentes foram Penicillium sp. (63,6%) e Aspergillus sp. (13,6%).
