Respiratory outcomes and survival after unplanned extubation in the NICU: a prospective cohort study from the SEPREVEN trial

OBJECTIVE

To compare reintubation rates after planned extubation and unplanned extubation (UE) in patients in neonatal intensive care units (NICUs), to analyse risk factors for reintubation after UE and to compare outcomes in patients with and without UE.

DESIGN

Prospective, observational study nested in a randomised controlled trial (SEPREVEN/Study on Epidemiology and PRevention of adverse EVEnts in Neonates). Outcomes were expected to be independent of the intervention tested.

SETTING

12 NICUs in France with a 20-month follow-up, starting November 2015.

PATIENTS

n=2280 patients with a NICU stay >2 days, postmenstrual age ≤42 weeks on admission.

INTERVENTIONS/EXPOSURE

Characteristics of UE (context, timing, sedative administration in the preceding 6 hours, weaning from ventilation at time of UE) and patients.

MAIN OUTCOME MEASURES

Healthcare professional-reported UE rates, reintubation/timing after extubation, duration of mechanical ventilation, mortality and bronchopulmonary dysplasia (BPD).

RESULTS

There were 162 episodes of UE (139 patients, median gestational age (IQR) 27.3 (25.6-31.7) weeks). Cumulative reintubation rates within 24 hours and 7 days of UE were, respectively, 50.0% and 57.5%, compared with 5.5% and 12.3% after a planned extubation. Independent risk factors for reintubation within 7 days included absence of weaning at the time of UE (HR, 95% CI) and sedatives in the preceding 6 hours (HR 1.93, 95% CI 1.04 to 3.60). Mortality at discharge did not differ between patients with planned extubation or UE. UE was associated with a higher risk of BPD.

CONCLUSION

In the SEPREVEN trial, reintubation followed UE in 58% of the cases, compared with 12% after planned extubation.

Father's perceptions and care involvement for their very preterm infants at French neonatal intensive care units

Objectives

We aimed to evaluate (1) fathers' perceptions and care involvement for their very premature infants and their views of the hospitalization period based on parental reports and (2) their evolution over time.

Methods

We used an online parental survey to assess answers from parents of very preterm infants who were successfully discharged from French neonatal units. We analysed answers from February 2014 to January 2019 to an anonymous internet-based survey from the GREEN committee of the French Neonatal Society. Responses were compared for period 1 (P1, 1998 to 2013) and period 2 (P2, 2014 to 2019).

Results

We analyzed 2,483 surveys, 124 (5%) from fathers and 2,359 (95%) from mothers. At birth, 1,845 (80%) fathers were present in the hospital, but only 879 (38%) were near the mother. The presence of fathers in the NICU increased from P1 to P2 (34.5% vs. 43.1%, p = 0.03). Nearly two thirds of fathers accompanied their infants during transfer to the NICU (1,204 fathers, 60.6%). Fathers and mothers had similar perceptions regarding relationships with caregivers and skin-to-skin contact with their infants. However, more fathers than mothers felt welcome in the NICU and in care involvement regarding requests for their wishes when they met their infant (79% vs. 60%, p = 0.02) and in the presentation of the NICU (91% vs. 76%; p = 0.03). Mothers and fathers significantly differed in the caring procedures they performed (p = 0.01), procedures they did not perform but wanted to perform (p < 0.001), and procedures they did not perform and did not want to perform (p < 0.01).

Conclusion

Most fathers were present at the births of their very preterm infants, but fewer fathers were near the mother at this time. Less than two thirds of fathers accompanied their infants to the NICU. There should be further changes to better meet the specific needs of the fathers of infants requiring care in the NICU. Continuing assessment with an online questionnaire may be useful to monitor changes over time in father's involvement in NICUs.

Circumstances, causes and timing of death in extremely preterm infants admitted to NICU: The EPIPAGE-2 study

AIM

To describe the circumstances, causes and timing of death in extremely preterm infants.

METHODS

We included from the EPIPAGE-2 study infants born at 24-26 weeks in 2011 admitted to neonatal intensive care units (NICU). Vital status and circumstances of death were used to define three groups of infants: alive at discharge, death with or without withholding or withdrawing life-sustaining treatment (WWLST). The main cause of death was classified as respiratory disease, necrotizing enterocolitis, infection, central nervous system (CNS) injury, other or unknown.

RESULTS

Among 768 infants admitted to NICU, 224 died among which 89 died without WWLST and 135 with WWLST. The main causes of death were respiratory disease (38%), CNS injury (30%) and infection (12%). Among the infants who died with WWLST, CNS injury was the main cause of death (47%), whereas respiratory disease (56%) and infection (20%) were the main causes in case of death without WWLST. Half (51%) of all deaths occurred within the first 7 days of life, and 35% occurred within 8 and 28 days.

CONCLUSION

The death of extremely preterm infants in NICU is a complex phenomenon in which the circumstances and causes of death are intertwined.

Error disclosure in neonatal intensive care: a multicentre, prospective, observational study

IMPORTANCE

Surveys based on hypothetical situations suggest that health-care providers agree that disclosure of errors and adverse events to patients and families is a professional obligation but do not always disclose them. Disclosure rates and reasons for the choice have not previously been studied.

OBJECTIVE

To measure the proportion of errors disclosed by neonatal intensive care unit (NICU) professionals to parents and identify motives for and barriers to disclosure.

DESIGN

Prospective, observational study nested in a randomised controlled trial (Study on Preventing Adverse Events in Neonates (SEPREVEN); ClinicalTrials.gov). Event disclosure was not intended to be related to the intervention tested.

SETTING

10 NICUs in France with a 20-month follow-up, starting November 2015.

PARTICIPANTS

n=1019 patients with NICU stay ≥2 days with ≥1 error.

EXPOSURE

Characteristics of errors (type, severity, timing of discovery), patients and professionals, self-reported motives for disclosure and non-disclosure.

MAIN OUTCOME AND MEASURES

Rate of error disclosure reported anonymously and voluntarily by physicians and nurses; perceived parental reaction to disclosure.

RESULTS

Among 1822 errors concerning 1019 patients (mean gestational age: 30.8±4.5 weeks), 752 (41.3%) were disclosed. Independent risk factors for non-disclosure were nighttime discovery of error (OR 2.40; 95% CI 1.75 to 3.30), milder consequence (for moderate consequence: OR 1.85; 95% CI 0.89 to 3.86; no consequence: OR 6.49; 95% CI 2.99 to 14.11), a shorter interval between admission and error, error type and fewer beds. The most frequent reported reasons for non-disclosure were parental absence at its discovery and a perceived lack of serious consequence.

CONCLUSION AND RELEVANCE

In the particular context of the SEPREVEN randomised controlled trial of NICUs, staff did not disclose the majority of errors to parents, especially in the absence of moderate consequence for the infant.

French Neonatal Society issues recommendations on preventing nasal injuries in preterm newborn infants during non-invasive respiratory support

AIM

To issue practical recommendations regarding the optimal care of nasal skin when non-invasive ventilation support is used.

METHODS

We performed a systematic search of PubMed to identify relevant papers published in English or French through December 2019. Different grades of evidence were evaluated.

RESULTS

Forty-eight eligible studies. The incidence in preterm infants was high. The lesions were more frequent for preterm infants born under 30 weeks of gestational age and/or below 1500 g. The lesion was most often located on the skin of the nose but could also be found on the intranasal mucous membranes or elsewhere on the face. Nasal injuries appear early after the beginning of non-invasive ventilation at a mean of 2-3 days for cutaneous lesions and eight or nine for intranasal lesions. The most effective strategies to prevent trauma are the use of a hydrocolloid at the beginning of the support ventilation, the preferential use of a mask and the rotation of ventilation interfaces.

CONCLUSION

Nasal injuries with continuous positive airway pressure treatment in preterm newborn infants were frequent and can induce pain, discomfort and sequelae. The immature skin of preterm newborn infants needs specific attention from trained caregivers and awareness by parents.

Determinants of morbidity and mortality related to health care-associated primary bloodstream infections in neonatal intensive care units: a prospective cohort study from the SEPREVEN trial

Background

Health care-associated primary bloodstream infections (BSIs), defined as not secondary to an infection at another body site, including central line-associated BSI, are a leading cause of morbidity and mortality in patients in neonatal intensive care units (NICUs). Our objective was to identify factors associated with severe morbidity and mortality after these infections in neonates in NICUs.

Methods

This ancillary study of the SEPREVEN trial included neonates hospitalized ≥2 days in one of 12 French NICUs and with ≥ 1 BSI during the 20-month study period. BSIs (all primary and health care-associated) were diagnosed in infants with symptoms suggestive of infection and classified prospectively as possible (one coagulase-negative staphylococci (CoNS)-growing blood culture) or proven (two same CoNS, or ≥1 recognized pathogen-growing blood culture). BSI consequences were collected prospectively as moderate morbidity (antibiotic treatment alone) or severe morbidity/mortality (life-saving procedure, permanent damage, prolonged hospitalization, and/or death).

Results

Of 557 BSIs identified in 494 patients, CoNS accounted for 378/557 (67.8%) and recognized bacterial or fungal pathogens for 179/557 (32.1%). Severe morbidity/mortality was reported in 148/557 (26.6%) BSIs. Independent factors associated with severe morbidity/mortality were corrected gestational age <28 weeks (CGA) at infection (P < .01), fetal growth restriction (FGR) (P = .04), and proven pathogen-related BSI vs. CoNS-related BSI (P < .01). There were no differences in severe morbidity and mortality between proven and possible CoNS BSIs. In possible BSI, S. epidermidis was associated with a lower risk of severe morbidity than other CoNS (P < .01), notably S. capitis and S. haemolyticus.

Conclusions

In BSIs in the NICU, severe morbidity/mortality was associated with low CGA at infection, FGR, and proven pathogen-related BSIs. When only one blood culture was positive, severe morbidity/mortality were less frequent if it grew with S. epidermidis compared to other CoNS. Further studies to help distinguish real CoNS BSIs from contaminations are needed.

Instrumental dead space: A glass ceiling for extremely low birth weight preterm infants? A dead space washout bench study

BACKGROUND

When ventilating extremely low birth weight infants, clinicians face the problem of instrumental dead space, which is often larger than tidal volume. Hence, aggressive ventilation is necessary to achieve CO₂ removal. Continuous tracheal gas insufflation can wash out CO₂ from dead space and might also have an impact on O₂ and water vapor transport. The objective of this bench study is to test the impact of instrumental dead space on the transport of CO₂ , O₂ , and water vapor and the ability of continuous tracheal gas insufflation to remedy this problem during small tidal volume ventilation.

METHODS

A test-lung located in an incubator at 37°C was ventilated with pressure levels needed to reach different tidal volumes from 1.5 to 5 mL. End-tidal CO₂ at the test-lung exit, O₂ concentration, and relative humidity in the test-lung were measured for each tidal volume with and without a 0.2 L/min continuous tracheal gas insufflation flow.

RESULTS

CO₂ clearance was improved by continuous tracheal gas insufflation allowing a 28%-44% of tidal volume reduction. With continuous tracheal gas insufflation, time to reach desired O₂ concentration was reduced from 20% to 80% and relative humidity was restored. These results are inversely related to tidal volume and are particularly critical below 3 mL.

CONCLUSION

For the smallest tidal volumes, reduction of instrumental dead space seems mandatory for CO₂ , O₂ , and water vapor transfer. Continuous tracheal gas insufflation improved CO₂ clearance, time to reach desired O₂ concentration and humidification of airways and, thus, may be an option to protect lung development.

Humidity during high-frequency oscillatory ventilation compared to intermittent positive pressure ventilation in extremely preterm neonates: An in vitro and in vivo observational study

BACKGROUND

Inappropriate humidification of inspired gas during mechanical ventilation can impair lung development in extremely low birthweight (ELBW) infants. Humidification depends on multiple factors, such as the heater-humidifier device used, type of ventilation, and environmental factors. Few studies have examined inspired gas humidification in these infants, especially during high-frequency oscillatory ventilation (HFOV). Our objective was to compare humidity during HFOV and intermittent positive pressure ventilation (IPPV), in vitro and in vivo.

METHODS

In vitro and in vivo studies used the same ventilator during both HFOV and IPPV. The bench study used a neonatal test lung and two heater-humidifiers with their specific circuits; the in vivo study prospectively included preterm infants born before 28 weeks of gestation.

RESULTS

On bench testing, mean absolute (AH) and relative (RH) humidity values were significantly lower during HFOV than IPPV (RH = 79.4 ± 8.1% vs. 89.0 ± 6.2%, p < 0.001). Regardless of the ventilatory mode, mean RH significantly differed between the two heater-humidifiers (89.6 ± 6.7% vs 78.7 ± 6.8%, p = 0.003). The in vivo study included 10 neonates (mean ± SD gestational age: 25.7 ± 0.9 weeks and birthweight: 624.4 ± 96.1 g). Mean RH during HFOV was significantly lower than during IPPV (74.6 ± 5.7% vs. 83.0 ± 6.7%, p = 0.004).

CONCLUSION

RH was significantly lower during HFOV than IPPV, both in vitro and in vivo. The type of heater-humidifier also influenced humidification. More systematic measurements of humidity of inspired gas, especially during HFOV, should be considered to optimize humidification and consequently lung protection in ELBW infants.

[Representations of skin-to-skin care among parents and caregivers in neonatology]

A study looked at the representations of skin-to-skin contact among parents and caregivers in seven neonatal units in France and Belgium. Their ways of understanding skin-to-skin contact have some common elements, without completely overlapping. The work carried out could prove useful for professionals who, thanks to it, would be likely to obtain a better understanding and adhesion of the families to the practice of this relational care.

Skin-to-skin SDF positioning: The key to intersubjective intimacy between mother and very preterm newborn-A pilot matched-pair case-control study

Background

Skin-to-skin contact (SSC) has been widely studied in NICU and several meta-analyses have looked at its benefits, for both the baby and the parent. However, very few studies have investigated SSC' benefits for communication, in particular in the very-preterm newborn immediately after birth.

Aims

To investigate the immediate benefits of Supported Diagonal Flexion (SDF) positioning during SSC on the quality of mother-very-preterm newborn communication and to examine the coordination of the timing of communicative behaviors, just a few days after birth.

Subjects and study design

Monocentric prospective matched-pair case-control study. Thirty-four mothers and their very preterm infants (27 to 31 + 6 weeks GA, mean age at birth: 30 weeks GA) were assigned to one of the two SSC positioning, either the Vertical Control positioning (n = 17) or the SDF Intervention positioning (n = 17). Mother and newborn were filmed during the first 5 min of their first SSC.

Outcome measures

Infants' states of consciousness according to the Assessment of Preterm Infants' Behavior scale (APIB). Onset and duration of newborns' and mothers' vocalizations and their temporal proximity within a 1-s time-window.

Results

In comparison with the Vertical group, very preterm newborns in the SDF Intervention Group spent less time in a drowsy state and more in deep sleep. At 3.5 days of life, newborns' vocal production in SSC did not differ significantly between the two groups. Mothers offered a denser vocal envelope in the SDF group than in the Vertical group and their vocalizations were on average significantly longer. Moreover, in a one-second time-frame, temporal proximity of mother-very preterm newborn behaviors was greater in the SDF Intervention Group.

Conclusion

Although conducted on a limited number of dyads, our study shows that SDF positioning fosters mother-very preterm newborn intimate encounter during the very first skin to skin contact after delivery. Our pioneer data sheds light on the way a mother and her very preterm vocally meet, and constitutes a pilot step in the exploration of innate intersubjectivity in the context of very preterm birth.

Practical recommendations on room sizes for hospitalised newborn infants and their families based on a systematic review of the literature

AIM

Neonatal unit design may affect the neurodevelopment of hospitalised neonates and the well-being of parents and healthcare staff (HCS). We aimed to provide recommendations regarding the minimum area required for a hospital room for a single neonate and their family.

METHODS

We searched PubMed and Web of Science for relevant articles published from 1 January 2011 to 1 May 2021 by using the keywords NICU and facility design. Recommendations were developed after internal and external review by a multidisciplinary group including 15 professionals and parent representatives.

RESULTS

We identified 314 studies and developed six recommendations from four eligible studies. Recommendations for room size were developed according to three perspectives: opinions of users, who emphasised the need for a spacious room; proposals of organisations by HCS, which advocated for a minimum floor area of 11.2-18 m² in a single non-family room and 15.3-24 m² in a single-family room; and simulation methods indicating that the minimum floor area in the neonatal unit should be 18.5-24 m² .

CONCLUSION

Units need to provide a minimum room size to allow for optimal newborn development and a better experience for parents and caregivers.

An educational programme in neonatal intensive care units (SEPREVEN): a stepped-wedge, cluster-randomised controlled trial

BACKGROUND

Patients in neonatal intensive care units (NICUs) are at high risk of adverse events. The effects of medical and paramedical education programmes to reduce these have not yet been assessed.

METHODS

In this multicentre, stepped-wedge, cluster-randomised controlled trial done in France, we randomly assigned 12 NICUs to three clusters of four units. Eligible neonates were inpatients in a participating unit for at least 2 days, with a postmenstrual age of 42 weeks or less on admission. Each cluster followed a 4-month multifaceted programme including education about root-cause analysis and care bundles. The primary outcome was the rate of adverse events per 1000 patient-days, measured with a retrospective trigger-tool based chart review masked to allocation of randomly selected files. Analyses used mixed-effects Poisson modelling that adjusted for time. This trial is registered with ClinicalTrials.gov, NCT02598609.

FINDINGS

Between Nov 23, 2015, and Nov 2, 2017, event rates were analysed for 3454 patients of these 12 NICUs for 65 830 patient-days. The event rate per 1000 patient-days reduced significantly from the control to the intervention period (33·9 vs 22·6; incidence rate ratio 0·67; 95% CI 0·50-0·88; p=0·0048).

INTERPRETATION

A multiprofessional safety-promoting programme in NICUs reduced the rate of adverse events and severe and preventable adverse events in highly vulnerable patients. This programme could significantly improve care offered to critically ill neonates.

Trust and consent: a prospective study on parents' perspective during a neonatal trial

OBJECTIVE

This study aimed to describe how parents and physicians experienced the informed consent interview and to investigate the aspects of the relationship that influenced parents' decision during the consent process for a randomised clinical trial in a tertiary neonatal intensive care unit (NICU). The secondary objective was to describe the perspectives of parents and physicians in the specific situation of prenatal informed consent.

SETTING

Single centre study in NICU of the Centre Hospitalier Intercommunal de Créteil, France, using a convenience period from February to May 2016.

DESIGN

Ancillary study to a randomised clinical trial: Prettineo. Records of interviews for consent.

POPULATION

parents and physicians. Mixed study including qualitative and quantitative interview data about participants' recall and feelings about the consent process. Interviews were reviewed using thematic discourse analysis.

RESULTS

Parents' recall and understanding of the study's main goal and design was good. Parents and physicians had a positive experience, and trust was one of the main reasons for parents to consent. Misunderstanding (bad comprehension) was the main reason for refusal.Before birth, three situations can compromise parents' consent: the mother already consented to participate in other studies, the absence of the father during the interview and the feeling that the baby's birth is not an imminent possibility.

CONCLUSIONS

Confronting parents and physicians' perspectives in research can help us reach answers to sensitive issues such as content and timing of information. Each different types of study raises different ethical dilemmas for consent that might be discussed in a more individual way.

Emotional responses of parents participating for the first time in caregiving for their baby in a neonatal unit

BACKGROUND

Parents of term and preterm infants hospitalised at birth experience a stressful situation. They are considered as primary caregivers in neonatal units and are encouraged to participate in their child's care.

OBJECTIVES

The aim of our study was to analyse the feelings of parents participating for the first time in caregiving for their baby admitted at birth in a neonatal unit in France and to compare the feelings reported by parents of term and preterm infants.

METHODS

An online survey was created in 2014 for parents who had a baby hospitalised at birth. We analysed parents' responses to this open-ended question: "How did you feel when you participated in caregiving for your baby for the first time?" using a qualitative discourse analysis by two analysts. Themes were identified and coded.

RESULTS

Between February 2014 and March 2018, 1603 parents of preterm infants and 239 parents of term infants responded to this open-ended question. Twenty-five per cent of parents expressed positive feelings exclusively (confidence, ease, joy, pride, feeling supported by healthcare professionals, by their family and feeling of being a parent), 41% expressed negative feelings exclusively (stress, fear, feeling of being judged, frustration, anger, uselessness and clumsiness) and 34% expressed mixed feelings (both positive and negative). Parents of term infants expressed less frequent feelings of stress and fear than parents of preterm infants: with a relative risk (RR) of 0.69, 95% confidence interval (CI) 0.56, 0.87. Parents of term babies more frequently expressed feelings of frustration: RR 2.40 (95% CI 1.33, 4.32).

CONCLUSIONS

Infant- and Family-Centred Developmental Care supportive programmes are recommended within neonatal units in order to improve the experience of parents participating in caregiving for their baby hospitalised at birth.

Targeting p16INK4a Promotes Lipofibroblasts and Alveolar Regeneration after Early-Life Injury

Rationale: Promoting endogenous pulmonary regeneration is crucial after damage to restore normal lungs and prevent the onset of chronic adult lung diseases.Objectives: To investigate whether the cell-cycle inhibitor p16^INK4a limits lung regeneration after newborn bronchopulmonary dysplasia (BPD), a condition characterized by the arrest of alveolar development, leading to adult sequelae.Methods: We exposed p16^INK4a-/- and p16^INK4a ATTAC (apoptosis through targeted activation of caspase 8) transgenic mice to postnatal hyperoxia, followed by pneumonectomy of the p16^INK4a-/- mice. We measured p16^INK4a in blood mononuclear cells of preterm newborns, 7- to 15-year-old survivors of BPD, and the lungs of patients with BPD.Measurements and Main Results: p16^INK4a concentrations increased in lung fibroblasts after hyperoxia-induced BPD in mice and persisted into adulthood. p16^INK4a deficiency did not protect against hyperoxic lesions in newborn pups but promoted restoration of the lung architecture by adulthood. Curative clearance of p16^INK4a-positive cells once hyperoxic lung lesions were established restored normal lungs by adulthood. p16^INK4a deficiency increased neutral lipid synthesis and promoted lipofibroblast and alveolar type 2 (AT2) cell development within the stem-cell niche. Besides, lipofibroblasts support self-renewal of AT2 cells into alveolospheres. Induction with a PPARγ (peroxisome proliferator-activated receptor γ) agonist after hyperoxia also increased lipofibroblast and AT2 cell numbers and restored alveolar architecture in hyperoxia-exposed mice. After pneumonectomy, p16^INK4a deficiency again led to an increase in lipofibroblast and AT2 cell numbers in the contralateral lung. Finally, we observed p16^INK4a mRNA overexpression in the blood and lungs of preterm newborns, which persisted in the blood of older survivors of BPD.Conclusions: These data demonstrate the potential of targeting p16^INK4a and promoting lipofibroblast development to stimulate alveolar regeneration from childhood to adulthood.

Study on preventing adverse events in neonates (SEPREVEN): A stepped-wedge randomised controlled trial to reduce adverse event rates in the NICU

INTRODUCTION

Adverse events (AE) in care are recognized as a leading cause of mortality and injury in patients. Improving patients' safety is difficult to achieve. Therefore, innovative research strategies are needed to identify errors in subgroups of patients and related severity of outcomes as well as reliably measured efficiency of reproducible strategies to improve safety. This trial aims to evaluate the impact of a combined multiprofessional education program on the rate of AE in neonatal intensive care units (NICUs).

METHODS AND ANALYSIS

This is a stepped-wedge cluster randomised controlled trial with 3 clusters each containing 4 units. The study time period will be 20 months. The education program will be implemented within each cluster following a random sequence with a control period, a 4-month transition period and a post-educational intervention period. Eligibility criteria: for clusters: 6 NICUs from Ile-de-France and 6 NICUs from different regions in France; for patients: in-hospital during the study period (November 23, 2015 and November 2, 2017 [inclusion start dates varying by unit]) in one of the 12 NICUs; corrected gestational age ≤42 weeks upon admission; hospitalization period >2 days; and parents informed and not opposed to the use of their newborn's data. A routine occurrence reporting of medical errors and their consequence will take place during the entire study period. The intervention will combine an education to implement a standardized root cause analysis method, creation of bundles (insertion, daily goals, maintenance bundles) to prevent catheter-associated blood-stream infection and a poster to prevent extravasation injuries.

OUTCOME

We hypothesize a reduction from 60 (control) to 50 (intervention) AE/1000 patient-days. The primary outcome will be the rate of AE/1000 patient-days in the NICU.

TRIAL REGISTRATION NUMBER

NCT02598609, trial registered November 6, 2015. https://clinicaltrials.gov/ct2/show/NCT02598609.

ETHICS AND DISSEMINATION

Recommendations on neonatal light environment from the French Neonatal Society

AIM

Hospital light may affect neonatal neurosensory development and the well-being of parents and caregivers. We aimed to issue practical recommendations regarding the optimal light environment for neonatal units.

METHODS

A systematic evaluation was performed using PubMed to identify relevant papers published in English or French up to July 2018, and the different grades of evidence were evaluated.

RESULTS

We identified 89 studies and one meta-analysis and examined 31 eligible studies. The major results were that natural or artificial light should not exceed 1000 lux and that all changes in light level should be gradual. Light protection should be used for infants of <32 weeks of postmenstrual age and but must be individualised to each infant. Infants should not be exposed to continuous high light levels regardless of their term and postnatal age. Cycled light before discharge seemed to be safe and beneficial. For medical caregivers' well-being, higher light levels and access to natural light are recommended. Special attention should be given to protecting neonatal patients from high light levels that may be necessary when performing specific care procedures.

CONCLUSION

Consideration of general principles and practical applications can improve the neonatal light environment for newborn infants, parents and caregivers.

French neonatal society position paper stresses the importance of an early family-centred approach to discharging preterm infants from hospital

AIM

The families of hospitalised preterm infants risk depression and post-traumatic stress and the preterm infants risk re-hospitalisation. The French neonatal society's aim was to review the literature on how the transition from hospital to home could limit these risks and to produce a position paper.

METHODS

A systematic literature review was performed covering 1 January 2000 to 1 January 2018, and multidisciplinary experts examined the scientific evidence.

RESULTS

We identified 939 English and French papers and 169 are quoted in the position paper. Most studies stressed the importance of early, personalised and progressive involvement of the family. Healthcare staff and families should assess discharge preparations jointly. This evaluation should assess the capacities of the newborn infant, with regard to its physiological maturity. It should also assess the family's ability to supply the medical, psychological and social assistance required before and after discharge. There should be a structured follow-up process that includes effective communication, various tools, interventions, networks, health and social professionals.

CONCLUSION

Discharge preparations may improve the transition from hospital to home and the outcomes for the parents and newborn preterm infant. This early family-centred approach should be structured, coordinated and based on individual needs and circumstances.

Fostering mother-very preterm infant communication during skin-to-skin contact through a modified positioning

BACKGROUND

Skin-to-skin contact (SSC) has been widely studied in NICU and several meta-analyses have looked at its benefits both for the baby and the parent. Very few studies however have investigated benefit for communication.

AIMS

Investigate the immediate benefits of Supported Diagonal Flexion (SDF) positioning during SSC on the quality of mother - very-preterm infant communication and to gain insight into how mothers' and very-preterm infants' communicative behaviours are coordinated in time just a few days after birth.

SUBJECTS AND STUDY DESIGN

Monocentric prospective matched-pair case-control study. Thirty-four mothers and their very preterm infants (27 to 31 + 6 weeks GA; mean age at birth 30: weeks GA) were assigned to one of the two SSC positioning, either the Vertical Control (n = 17) or the SDF Intervention positioning (n = 17). Mother and infant were filmed during the first 5 min of SSC, 15 days after the very first SSC (i.e. 18 days after very premature birth, i.e. on average 32.4 weeks GA).

OUTCOME MEASURES

Infants' state of consciousness according to the Assessment of Preterm Infants' Behavior scale. Onset and duration of infants' and mothers' smiles, gazes and vocalizations, and their temporal proximity inside a 1-sec time-window.

RESULTS

In the SDF Intervention Group, very preterm infants vocalized three times more and mothers vocalized, gazed at their baby's face, and smiled more than in the Vertical Control Group. Moreover, in a one-second time-frame, temporal proximity of mother-infant behaviours was greater in the SDF Intervention Group.

CONCLUSIONS

Our study shows that SDF positioning creates more opportunities for mother-infant communication during SSC. SDF positioning fosters a greater multimodal temporal proximity thus supporting a more qualitative mother-infant communication.

Continuous intravenous to oral morphine switch in very premature ventilated infants: A retrospective study on efficacy, efficiency, and tolerability

Background

Continuous intravenous (IV) morphine is commonly used in ventilated neonates. Oral route is theoretically feasible but data on oral morphine in ventilated premature infants are lacking.

Objective

To assess the efficacy, efficiency, and tolerability of a continuous intravenous to oral morphine switch protocol.

Design

Retrospective study.

Setting

Single level III center's neonatal intensive care unit.

Patients

Ventilated premature infants hospitalized in the NICU in 2016 and 2017, receiving continuous IV morphine with an expected ventilation course of at least 72 more hours. We excluded patients treated for withdrawal syndrome or palliative care.

Interventions

Continuous IV to oral morphine switch with the same initial cumulated daily dose.

Main outcome measures

Pain scores (ComfortNeo scale) and morphine doses were analyzed over time using Friedman's test in the 24 hours preceding and the 48 hours following the oral switch. Adverse effects attributable to opioids were collected.

Results

Seventeen infants were included with a median [IQR] gestational age at birth of 25.9 [24.6‐26.9] weeks and a median postnatal age at oral switch of 30 [22‐36] days. One patient's intravenous treatment had to be resumed because of a high ComfortNeo score. All others remained on oral morphine. No significant change over time was observed for ComfortNeo scores (P = .15). Median [IQR] doses were 13.5 [10‐20] µg/kg/h in the IV period and significantly increased to 15 [10‐25] µg/kg/h in the oral period (P = .009). No short‐term respiratory, digestive, or urinary adverse event was observed. After a median [IQR] duration of 13 [4‐20] days of oral morphine treatment, 11 (65%) patients showed signs of withdrawal. Upon hospital discharge, 16 infants (94%) had bronchopulmonary dysplasia and none had severe cerebral abnormality on brain imaging.

Conclusion

Oral morphine might be useful in ventilated neonates in the NICU but deserves further studies and additional safety assessment.

Pharmacokinetic and pharmacodynamic considerations of cephalosporin use in children

Introduction: Cephalosporins are a major class of antibiotics, frequently used in children because of their remarkable antibacterial activity and excellent safety profile. Time above the minimal inhibitory concentration of the non-protein-bound fraction (fT>MIC) is the pharmacokinetic/pharmacodynamic parameter that correlates with the therapeutic efficacy. In the pediatric population, the inter-individual variability in cephalosporin pharmacokinetics is large because of maturational changes. However, the prescription of cephalosporins promotes emergence of Enterobacteriaceae producing broad-spectrum ß-lactamases.Areas covered: Here we describe in vitro activities and the main pharmacokinetic characteristics of cephalosporins in children. On the basis of these characteristics, we propose an estimation of the fT>MIC for each molecule as a tool to help optimize the use of cephalosporins. We also provide an inventory of the clinical use of cephalosporins and present prospects for the development of new molecules or associations to address the emergence of resistant strains.Expert opinion: Cephalosporins represent a heterogeneous group of antibiotics with various pharmacokinetics and in vitro antimicrobial activity that the clinician needs to master to optimize their use. However, their broad use plays a role in the emergence of broad-spectrum ß-lactamase-producing strains and must thus be restricted to probabilistic broad-spectrum therapy and situations without therapeutic alternatives.

Characteristics of prescription in 29 Level 3 Neonatal Wards over a 2-year period (2017-2018). An inventory for future research

Objectives

The primary objective of this study is to determine the current level of patient medication exposure in Level 3 Neonatal Wards (L3NW). The secondary objective is to evaluate in the first month of life the rate of medication prescription not cited in the Summary of Product Characteristics (SmPC). A database containing all the medication prescriptions is collected as part of a prescription benchmarking program in the L3NW.

Material and methods

The research is a two-year observational cohort study (2017–2018) with retrospective analysis of medications prescribed in 29 French L3NW. Seventeen L3NW are present since the beginning of the study and 12 have been progressively included. All neonatal units used the same computerized system of prescription, and all prescription data were completely de-identified within each hospital before being stored in a common data warehouse.

Results

The study population includes 27,382 newborns. Two hundred and sixty-one different medications (International Nonproprietary Names, INN) were prescribed. Twelve INN (including paracetamol) were prescribed for at least 10% of patients, 55 for less than 10% but at least 1% and 194 to less than 1%. The lowest gestational ages (GA) were exposed to the greatest number of medications (18.0 below 28 weeks of gestation (WG) to 4.1 above 36 WG) (p<0.0001). In addition, 69.2% of the 351 different combinations of an medication INN and a route of administration have no indication for the first month of life according to the French SmPC. Ninety-five percent of premature infants with GA less than 32 weeks received at least one medication not cited in SmPC.

Conclusion

Neonates remain therapeutic orphans. The consequences of polypharmacy in L3NW should be quickly assessed, especially in the most immature infants.

Prenatal parental involvement in decision for delivery room management at 22-26 weeks of gestation in France - The EPIPAGE-2 Cohort Study

OBJECTIVE

Our main objective was to examine if parental prenatal preferences predict delivery-room management of extremely preterm periviable infants. The secondary objectives were to describe parental involvement and the content of prenatal counseling given to parents for this prenatal decision.

DESIGN

Prospective study of neonates liveborn between 22 and 26 weeks of gestation in France in 2011 among the neonates included in the EPIPAGE-2 study.

SETTING

18 centers participating in the "Extreme Prematurity Group" substudy of the EPIPAGE-2 study.

PATIENTS

302 neonates liveborn between 22-26 weeks among which 113 with known parental preferences while parental preferences were unknown or unavailable for 186 and delivery room management was missing for 3.

RESULTS

Data on prenatal counseling and parental preferences were collected by a questionnaire completed by professionals who cared for the baby at birth; delivery room (DR) management, classified as stabilization or initiation of resuscitation (SIR) vs comfort care (CC). The 113 neonates studied had a mean (SD) gestational age of 24 (0.1) weeks. Parents of neonates in the CC group preferred SIR less frequently than those with neonates in the SIR group (16% vs 88%, p < .001). After multivariate analysis, preference for SIR was an independent factor associated with this management. Professionals qualified decisions as shared (81%), exclusively medical (16%) or parental (3%). Information was described as medical with no personal opinion (71%), complete (75%) and generally pessimistic (54%).

CONCLUSION

Parental involvement in prenatal decision-making did not reach satisfying rates in the studied setting. When available, prenatal parental preference was a determining factor for DR management of extremely preterm neonates. Potential biases in the content of prenatal counselling given to parents need to be evaluated.

Continuous-Infusion Vancomycin in Neonates: Assessment of a Dosing Regimen and Therapeutic Proposal

Introduction: Vancomycin remains the reference antibiotic in neonates for care-related infections caused by ß-lactam-resistant Gram-positive bacteria. Achieving the optimal serum vancomycin level is challenging because of high inter-individual variability and the drug's narrow therapeutic window. Continuous infusion might offer pharmacokinetic and practical advantages, but we lack consensus on the dosing regimen. The aim was to determine the proportion of neonates achieving an optimal therapeutic vancomycin level at the first vancomycin concentration assay and which dosing regimen is the most suitable for neonates. Methods: All neonates receiving continuous-infusion vancomycin (loading dose 15 mg/kg and maintenance dose 30 mg/kg/d) in a neonatal intensive care unit were retrospectively analyzed. The proportion of neonates reaching the target serum vancomycin level was calculated. After reviewing the literature to identify all published articles proposing a dosing regimen for continuous-infusion vancomycin for neonates, regimens were theoretically applied to our population by using maintenance doses according to covariate(s) proposed in the original publication. Results: Between January 2013 and December 2014, 75 neonates received 91 vancomycin courses by continuous infusion. Median gestational age, birth weight, and postnatal age were 27 weeks (interquartile range 26-30.5), 815 g (685-1,240), and 15 days (9-33). At the first assay, only 28/91 (30.8%) courses resulted in vancomycin levels between 20 and 30 mg/L (target level), 23/91 (25.3%) >30 mg/L and 40/91 (43.9%) <20 mg/L. We applied six published dosing regimens to our patients. One of these dosing regimens based on corrected gestational age (CGA) and serum creatinine level (SCR) would have allowed us to prescribe lower doses to neonates with high vancomycin levels and higher doses to neonates with low levels. Conclusions: A simplified dosing regimen of continuous-infusion vancomycin did not achieve therapeutic ranges in neonates; a patient-tailored dosing regimen taking into account CGA and SCR level or an individualized pharmacokinetic model can help to anticipate the inter-individual variability in neonates and would have been more suitable.

Combination therapy with ciprofloxacin and third-generation cephalosporin versus third-generation cephalosporin monotherapy in Escherichia coli meningitis in infants: a multicentre propensity score-matched observational study

OBJECTIVES

Escherichiacoli is the second cause of bacterial meningitis in neonates. Despite the use for 35 years of third-generation cephalosporins (3GCs), high morbidity and mortality rates with E. coli meningitis continue to occur. Because ciprofloxacin has good microbiologic activity against E. coli and good penetration in cerebrospinal fluid and brain, some authors have suggested adding ciprofloxacin to a 3GC regimen. The objective of this study was to assess combining 3GCs with ciprofloxacin versus 3GCs alone in a cohort of infants with E. coli meningitis.

METHODS

We included all cases of E. coli meningitis diagnosed in infants <12 months of age that were prospectively collected through the French paediatric meningitis surveillance network between 2001 and 2016. The main outcome was the proportion of short-term neurologic complications with versus without ciprofloxacin. The analysis was conducted retrospectively by multivariable regression and propensity score (PS) analysis.

RESULTS

Among the 367 infants enrolled, 201 (54.8%) of 367 had ciprofloxacin and 3GC cotreatment and 166 (45.2%) of 367 only a 3GC. Median age and weight were 15 days (range, 1-318 days) and 3.42 kg (range, 0.66-9.4 kg). A total of 86 (23.4%) of 367 infants presented neurologic complications (seizures, strokes, empyema, abscesses, hydrocephalus, arachnoiditis); 57 received ciprofloxacin cotreatment. Complications were associated with ciprofloxacin cotreatment on multivariable analysis (odds ratio (OR) = 1.9; 95% confidence interval (CI), 1.1-3.4) and PS analysis (OR = 1.9; 95% CI, 1.1-3.3). Mortality rate did not differ with and without ciprofloxacin: 22 (10.9%) of 201 versus 16 (9.6%) of 166 deaths (OR = 0.7; 95% CI, 0.3-1.6; PS analysis).

CONCLUSIONS

Ciprofloxacin added to 3GCs at least offers no advantage for neurologic outcome and mortality in infants with E. coli meningitis.

Klebsiella pneumoniae and Klebsiella oxytoca meningitis in infants. Epidemiological and clinical features

BACKGROUND

The incidence of meningitis caused by Klebsiella pneumoniae (Kp) and Klebsiella oxytoca (Ko) in high-income countries is unknown, and no series have been published to date.

METHODS

We conducted a nationwide multicenter observational study in France between 2006 and 2016. All children from the French national registry for paediatric bacterial meningitis under the age of 1 year and hospitalized for Kp or Ko meningitis were included. Virulence factors of four Klebsiella spp. strains were explored by whole genome sequencing.

RESULTS

Of 1859 cases of meningitis in children under the age of 1 year, 13 cases (0.7%) of Klebsiella spp. meningitis (nine for Kp meningitis and four for Ko meningitis) were registered in the French national registry. Three of the patients died and 50% of the survivors had developmental delays.

CONCLUSIONS

Prematurity, low birth weight, and congenital anomalies of the urinary tract appear to be risk factors for Klebsiella spp. meningitis as well as virulence factors of the strain.

Pharmacocinétique et pharmacodynamie des antibiotiques : est-ce différent en néonatologie ?

Pharmacokinetic and pharmacodynamics (PK/PD) data on antimicrobial agents enable physicians to optimize their use in clinical practice. Neonates exhibit a large inter-individual variability in antibiotic levels due to immaturity and maturational changes in the first weeks of life. This variability explains the large therapeutic margins needed to ensure an optimal efficacy of antibiotics. These pharmacokinetic characteristics have to be taken into account when treating neonatal sepsis, along with pharmacodynamics targets for each antibiotic and notably minimal inhibitory concentration for usual causes of neonatal bacterial infections (group B streptococcus and Escherichia coli). This paper presents PK/PD data of antimicrobial agents mainly used in neonatology (ß-lactamines and aminoglycosides) to help physicians to rationalize their use of antibiotics.

Administering atropine and ketamine before less invasive surfactant administration resulted in low pain scores in a prospective study of premature neonates

AIM

Less invasive surfactant administration (LISA) can avoid tracheal intubation for neonatal respiratory distress syndrome, but can be painful because it requires laryngoscopy. The aim of this study was to assess the efficacy and tolerance of intravenous atropine plus ketamine administration before LISA.

METHODS

We conducted a prospective observational study of all premature infants hospitalised in our French neonatal intensive care unit treated with LISA between March 2015 and March 2016. Ketamine was titrated by 0.5 mg/kg increments. The technical conditions, pain scores, emergent intubations and vital signs were collected and analysed.

RESULTS

Values are reported as medians (interquartile ranges). We included 29 patients with a gestational age of 29.6 (28.6-30.9) weeks and birth weight of 1290 (945-1600) grams. Technical conditions were satisfying for 24 infants (83%). The Faceless Acute Neonatal Pain Scale score was 2 (2-4); seven infants (24%) required tracheal intubation before LISA could be performed; 17 (59%) had a pulse oxymetry value under 80% that lasted more than 60 seconds. Heart rate and mean arterial blood pressure transiently increased.

CONCLUSION

Atropine plus ketamine before LISA resulted in low pain scores and stable haemodynamic parameters, but prolonged desaturations or apnoea leading to tracheal intubation were frequently observed.

Delivery room deaths of extremely preterm babies: an observational study

OBJECTIVE

Many extremely preterm neonates die in the delivery room (DR) after decisions to withhold or withdraw life-sustaining treatments or after failed resuscitation. Specific palliative care is then recommended but sparse data exist about the actual management of these dying babies. The objective of this study was to describe the clinical course and management of neonates born between 22 and 26 weeks of gestation who died in the DR in France.

DESIGN, SETTING, PATIENTS

Prospective study including neonates, who were liveborn between 22⁺⁰ and 26⁺⁶ weeks of gestation and died in the DR in 2011, among infants included in the EPIPAGE-2 study at the 18 centres participating in this substudy of extremely preterm neonates. Data were collected by a questionnaire completed by the professional caring for each baby.

RESULTS

The study included 73 children, with a median (IQR) gestational age of 24 (23-24) weeks. Median (IQR) duration of life was 53 (20-82) min. All but one were both wrapped and warmed. Pain was assessed for 72%, although without using any scale. Gasping was described for 66%. Comfort medications were administered to 35 children (50%), significantly more frequently to babies with gasping (p=0.001). Mother-child contact was reported for 78%, and psychological support offered to parents of 92%.

CONCLUSIONS

Non-pharmacological comfort care and parental support were routinely given. Comfort medication was given much more frequently than previously reported in other DRs. These data should encourage work on the indications for comfort medication and the interpretation of gasping.

[Parental perception of their involvement in the care of their children in French neonatal units]

BACKGROUND

The experience of becoming the parent of a sick or premature newborn can be particularly distressing for parents. They often encounter challenges to the development of their parenting roles. Perception of the hospital stay has never been analyzed on a large scale.

OBJECTIVE

To analyze parents' perception of their involvement in the care of their newborn.

METHODS

An internet-based survey started in France in February 2014 on the basis of a validated questionnaire composed of 222 neonatal care-related items. A quantitative and qualitative analysis was performed on the items dealing with parents' involvement until August 2014.

RESULTS

The survey was completed by 1500 parents, 98 % of whom were mothers. The infants had a mean GA of 32 weeks and a mean birth weight of 1600g. Parents rated their first care of their infant with mixed emotions (joy, stress, etc.). Parents were willing to practice new skills through guided participation, even for more complex care. Skin-to-skin care was only proposed after 7 days for 20 % of the parents; 10 % of the parents did not feel secure during this practice. The need for privacy and professional guidance was essential for meaningful skin-to-skin contact.

DISCUSSION

Parents' perception of participating actively in their infant's care was positive and they felt guided by the nursing team. Most of them would have been more active with guidance. Skin-to-skin care was appreciated and desired, but could become stressful if the conditions were not optimal.

Assessment of atropine-sufentanil-atracurium anaesthesia for endotracheal intubation: an observational study in very premature infants

Background

Premedication before neonatal intubation is heterogeneous and contentious. The combination of a short acting, rapid onset opioid with a muscle relaxant is considered suitable by many experts. The purpose of this study was to describe the tolerance and conditions of intubation following anaesthesia with atropine, sufentanil and atracurium in very premature infants.

Methods

Monocentric, prospective observational study in premature infants born before 32 weeks of gestational age, hospitalised in the NICU and requiring semi-urgent or elective intubation. Intubation conditions, heart rate, pulse oxymetry (SpO₂), arterial blood pressure and transcutaneous PCO₂ (TcPCO₂) were collected in real time during 30 minutes following the first drug injection. Repeated physiological measurements were analysed using mixed linear models.

Results

Thirty five intubations were performed in 24 infants with a median post conceptional age of 27.6 weeks and a median weight of 850 g at the time of intubation. The first attempt was successful in 74% and was similar for junior (75%) and senior (74%) operators. The operator rated conditions as “excellent” or “good” in 94% of intubations. A persistent increase in TcPCO₂ as compared to baseline was observed whereas other vital parameters showed no significant variations 5, 10, 15 and 30 minutes after the first drug injection. Eighteen (51%) desaturations (SpO2 less than or equal to 80% for more than 60 seconds) and 2 (6%) bradycardia (heart rate less than100 bpm for more than 60 seconds) were observed.

Conclusion

This drug combination offers satisfactory success rate for first attempt and intubation conditions for the operator without any significant change in heart rate and blood pressure for the patient. However it is associated with frequent desaturations and a possible persistent hypercapnia. SpO₂ and PCO₂ can be significantly modified during neonatal intubation and should be cautiously followed in this high-risk population.

Parents' expectations of staff in the early bonding process with their premature babies in the intensive care setting: a qualitative multicenter study with 60 parents

BACKGROUND

During the first weeks of hospitalization, premature babies and their parents encounter difficulties in establishing early bonds and interactions. Only a few studies have explored what caregivers can do to meet parents' needs in relation to these interactions and help optimize them. This study sought to explore parents' perception of these first interactions and to identify the actions of caregivers that help or hinder its development.

METHODS

Prospective study, qualitative discourse analysis of 60 face-to-face interviews conducted with 30 mothers and 30 fathers of infants born before 32 weeks of gestation (mean ± SD: 27 ± 2 weeks of gestational age), during their child's stay in one out of three NICUs in France. Interviews explored parental experience, from before birth up to the first month of life.

RESULTS

Data analysis uncovered two main themes, which were independent of parents' geographical or cultural origin but differed between mothers and fathers. First, fathers described the bond with their child as composed more of words and looks and involving distance, while mothers experienced the bond more physically. Secondly, two aspects of the caregivers' influence were decisive: nurses' caring attitude towards baby and parents, and their communication with parents, which reduced stress and made interactions with the baby possible. This communication appeared to be the locus of a supportive and fulfilling encounter between parents and caregivers that reinforced parents' perception of a developing bond.

CONCLUSIONS

At birth and during the first weeks in the NICU, the creation of a bond between mothers and fathers and their premature baby is rooted in their relationship with the caregivers. Nurses' caring attitude and regular communication adapted to specific needs are perceived by parents as necessary preconditions for parents' interaction and development of a bond with their baby. These results might allow NICU staff to provide better support to parents and facilitate the emergence of a feeling of parenthood.

Perceived role in end-of-life decision making in the NICU affects long-term parental grief response

BACKGROUND

Shared decision making (DM) is increasingly advocated as the most appropriate model to support parents confronted with end-of-life (EoL) decisions for a child in the neonatal intensive care unit (NICU). However, few studies have explored its impact on their long-term grief.

OBJECTIVES

The aim of this study was to investigate whether parental perception of the type of involvement in the EoL decision-making process (EoL DMP) for their child in the NICU is related to their long-term grief outcome.

METHODS

A retrospective study with mixed methods. The study included parents whose child died from 2002 through 2005 in one of four NICUs in different areas in France, with interviews of 78 individual parents of 53 children, 2.7 ± 0.6 years after the child's death. Parental perception of the type of involvement in the EoL DMP was determined by qualitative analysis of face-to-face interviews and classified as follows: shared, medical, informed parental and no decision. Grief reactions were assessed with the Texas Revised Inventory of Grief (TRIG-F).

RESULTS

Current grief scores differed significantly according to the perceived type of EoL DM. Shared DM was associated with lower TRIG-F scores (less grief) than were the other types of EoL DM (F=7.95; p=0.05). The baby's perceived suffering was also associated with higher grief scores (F=6.51, p=0.01).

CONCLUSIONS

In decisions to forego life-sustaining treatment in the NICU, the perception of a shared decision is associated in the long term with lower grief scores than perceptions of the other types of DM.

Living with a crucial decision: a qualitative study of parental narratives three years after the loss of their newborn in the NICU

BACKGROUND

The importance of involving parents in the end-of-life decision-making-process (EOL DMP) for their child in the neonatal intensive care unit (NICU) is recognised by ethical guidelines in numerous countries. However, studies exploring parents' opinions on the type of involvement report conflicting results. This study sought to explore parents' experience of the EOL DMP for their child in the NICU.

METHODS

The study used a retrospective longitudinal design with a qualitative analysis of parental experience 3 years after the death of their child in four NICUs in France. 53 face-to-face interviews and 80 telephone interviews were conducted with 164 individuals. Semi-structured interviews were conducted to explore how parents perceived their role in the decision process, what they valued about physicians' attitudes in this situation and whether their long-term emotional well being varied according to their perceived role in the EOL DMP.

FINDINGS

Qualitative analysis identified four types of perceived role in the DMP: shared, medical, informed parental decision, and no decision. Shared DM was the most appreciated by parents. Medical DM was experienced as positive only when it was associated with communication. Informed parental DM was associated with feelings of anxiousness and abandonment. The physicians' attitudes that were perceived as helpful in the long term were explicit sharing of responsibility, clear expression of staff preferences, and respectful care and language toward the child.

INTERPRETATION

Parents find it valuable to express their opinion in the EOL DMP of their child. Nonetheless, they do need continuous emotional support and an explicit share of the responsibility for the decision. As involvement preferences and associated feelings can vary, parents should be able to decide what role they want to play. However, our study suggests that fully autonomous decisions should be misadvised in these types of tragic choices.

Ethically complex decisions in the neonatal intensive care unit: impact of the new French legislation on attitudes and practices of physicians and nurses

OBJECTIVES

A statute enacted in 2005 modified the legislative framework of the rights of terminally ill persons in France. Ten years after the EURONIC study, which described the self-reported practices of neonatal caregivers towards ethical decision-making, a new study was conducted to assess the impact of the new law in neonatal intensive care units (NICU) and compare the results reported by EURONIC with current practices.

SETTING AND DESIGN

The study was carried out in the same two NICU as in the EURONIC qualitative study. A third centre was added to increase the sample size. From February to October 2007, 19 physicians and 17 nurses participated in semistructured interviews very similar to those for EURONIC. Content analysis identified the recurring themes emerging from the interviews.

RESULTS

Compared with the EURONIC results, the caregivers reported that they pay greater attention to the views of parents and provided respectful support to the neonates when life-sustaining treatment is withdrawn. Active termination of life has become exceptional. The possibility of withdrawal of treatment, the administration of sedatives to control pain even at the risk of hastening death, the emphasis on sparing parents the burden of decision, and the relative ignorance of the law were very similar to the EURONIC findings.

CONCLUSION

Both the medical and the legal regulation of practices has allowed more dialogue with the parents and more humane care for dying newborns. A new European study is necessary to investigate the possible changes in practices and attitudes also in other countries.

[Very premature births: Dilemmas and management. Second part: Ethical aspects and recommendations]

In the first part of this work, the outcome following very premature birth was assessed. This enabled a gray zone to be defined, with inherent major prognostic uncertainty. In France today, the gray zone corresponds to deliveries occurring at 24 and 25 weeks of postmenstrual age. The management of births occurring below and above the gray zone was described. Withholding intensive care at birth for babies born below or within the gray zone does not mean withholding care but rather providing palliative care to prevent pain and suffering during the time period preceding death. Given the high level of uncertainty, making good decisions within the gray zone is problematic. Decisions should be based on the infant's best interests. Decisions should be reached with the parents, who are entitled to receive clear and comprehensive information. Possible decisions to withhold intensive care should be made following the procedures described in the French law of April 2005. Guidelines, based on gestational age and the other prognostic elements, are proposed to the parents before birth. They are applied in an individualized fashion, in order to take into account the individual features of each case. At 25 weeks, resuscitation and/or full intensive care are usually proposed, unless unfavorable factors, such as severe growth restriction, are associated. A senior neonatologist will attend the delivery and will make decisions based on both the baby's condition at birth and the parents' wishes. At 24 weeks, in the absence of unfavorable associated factors, the parents' wishes should be followed in deciding between initiating full intensive care or palliative care. Below 24 weeks, palliative care is the only option to be offered in France at the present time.

[Very premature births: Dilemmas and management. Part 1. Outcome of infants born before 28 weeks of postmenstrual age, and definition of a gray zone]

With very preterm deliveries, the decision to institute intensive care, or, alternatively, to start palliative care and let the baby die, is extremely difficult, and involves complex ethical issues. The introduction of intensive care may result in long-term survival of many infants without severe disabilities, but it may also result in the survival of severely disabled infants. Conversely, the decision to withhold resuscitation and/or intensive care at birth, which is an option at the margin of viability, implies allowing babies to die, although some of them would have developed normally if they had received resuscitation and/or intensive care. Withholding intensive care at birth does not mean withholding care but rather providing palliative care to prevent pain and suffering during the time period preceding death. The likelihood of survival without significant disabilities decreases as gestational age at birth decreases. In addition to gestational age, other factors greatly influence the prognosis. Indeed, for a given gestational age, higher birth weight, singleton birth, female sex, exposure to prenatal corticosteroids, and birth in a tertiary center are favorable factors. Considering gestational age, there is a gray zone that corresponds to major prognostic uncertainty and therefore to a major problem in making a "good" decision. In France today, the gray zone corresponds to deliveries at 24 and 25 weeks of postmenstrual age. In general, babies born above the gray zone (26 weeks of postmenstrual age and later) should receive resuscitation and/or full intensive care. Below 24 weeks, palliative care is the only option offered in France at the present time. Decisions within the gray zone will be addressed in the 2nd part of this work.

L'information dans le contexte du soin périnatal: aspects éthiques

Besides the undeniable need to respect parental autonomy, providing information is a legal and moral obligation, to be informed a basic right. The act of informing should be considered as an exchange and necessarily begins by listening to the other. According to the jurisprudence of the Court of Cassation that draws on Article 35 of the Deontological Code, information has to be clear (implying an educational effort, availability and to check that the information has been well understood), appropriate (adapted to each situation and person) and honest (which supposes a moral contract between parents and physicians). Loyalty implies a consideration of the uncertainty underlying medical practice, and of the limitations in arriving at a prognosis. Indeed, caution needs to be exercised in conveying information, taking into account the risk of its becoming self-fulfilling, which could modify the way in which parents take care of their child. The information given has to be coherent, both within the spatial dimension (coherence of information between the different maternity services in the perinatal network) and the temporal dimension (coherence of information between pre- and postnatal stages). It must be acknowledged that information is essentially subjective. There is a fundamental difference between coherence and uniformity, and as regards information, uniformity is neither possible nor desirable. In each situation, priority must be given to oral information delivered in an appropriate material context. The principle of establishing, in the medical file, a written trace of the information given at various stages is one way to guarantee its coherence.

Cocaïne et trisomie 8 associées au diagnostic prénatal d’agénésie du corps calleux

We report the case of a newborn presenting an agenesis of corpus callosum (ACC) discovered in the prenatal period and initially related to cocaine exposure during the first trimester of gestation. The cytogenetic analysis revealed a trisomy 8 mosaicism. The putative role of prenatal cocaine exposure and mosaicism for chromosome 8 in ACC are discussed. This report emphasizes the specific analysis of chromosome 8 by using fluorescence in situ hybridization as a complement to routine cytogenetic analysis for prenatal diagnosis of ACC.

[Retro-tracheal left pulmonary artery. Report of 2 cases]

The authors report the cases of two neonates with retro-tracheal left pulmonary arteries (pulmonary artery sling). In the first case, there was rapid onset of cardiac failure with signs of airway compression. Echocardiography showed the vascular anomaly associated with a large ventricular septal defect (VSD). After standard radiological investigation and bronchoscopy to exclude an associated tracheo-bronchial malformation, the VSD was repaired surgically with reimplantation of the left pulmonary artery. Unfortunately, the patient died of major airways obstruction in the postoperative period. Autopsy showed tracheo-bronchial anomalies which had not been diagnosed preoperatively. The second patient presented with hypoventilation of the right lung. After echocardiographic diagnosis of the anomaly, a thorough investigation (thoracic CT, helicoidal scan, bronchoscopy) was carried out and no associated bronchial malformations were observed. Reimplantation of the left pulmonary artery was successful and the postoperative course was uneventful. Retro-tracheal left pulmonary artery is a rare malformation Which is difficult to diagnose. It requires extensive pulmonary investigations and a multi-disciplinary approach. The prognosis is poor when there are associated tracheo-bronchial malformations.

[Neurological prognosis of term infants with perinatal asphyxia]

Neonatal encephalopathies following birth asphyxia are the first features of cerebral insult. They never miss when asphyxia is directly involved in cerebral impairment. Mild encephalopathies have constantly a good prognosis. Conversely, moderate and severe encephalopathies are associated with poor outcome (death or severe handicap) in 25% to 100% of cases. Prognosis of these moderate and severe encephalopathies can be assessed during the first ten days of life by 3 complementary ways: clinical exam, electrophysiology and imaging. The most information is obtained from the EEG and MRI which together nearly reach 100% for both predictive positive and negative values for severe neurological sequelae.

Surgical necrotizing enterocolitis: are intestinal lesions more severe in infants with low birth weight?

PURPOSE

This study examines whether the intestinal lesions of necrotizing enterocolitis (NEC) in infants undergoing surgery are more severe in patients with extremely low birth weight (BW).

METHODS

Between 1980 and 2000, 128 infants underwent laparotomy for NEC: 90 in the acute phase, and 38 for secondary stenosis. Resections were limited to areas of transparietal bowel necrosis and to secondary stenoses. The authors studied the extent of initial bowel lesions at initial laparotomy, and, in the survivors, the extent of bowel resections and the existence of digestive sequelae, with a median follow-up of 24 (range, 1 to 247) months. Children with BW < or =1,000 g (group 1, 22 patients) and greater than 1,000 g (group 2, 103 patients) were compared by using chi(2) and t test.

RESULTS

Patients' survival rate was 87%: 68% and 91% in the groups 1 and 2, respectively (P =.01). No significant difference between the 2 groups was seen: (1) for the rate of patients with panintestinal lesions at initial surgery (12%); (2) in the survivors, the ratio of remaining to total length of jejuno-ileum (mean 88%), the number of colonic segments resected (mean 1.2), the rate of survivors without distal ileum (34%), ileo-caecal valve (39%), or right colon (29%); and (3) for the existence of digestive symptoms, even minor, at last follow-up (25%).

CONCLUSIONS

Although the prognosis of surgical NEC was worse in infants with extremely low birth weight, the intestinal lesions were not found more severe in these patients.

[Chronic cor pulmonale and refractory hypoxemia following pulmonary embolism in a six-month-old infant: surgical management by thromboendarterectomy]

A diagnosis of pulmonary embolism is uncommon in the infant and the child, and chronic cor pulmonale secondary to pulmonary embolism is an even rarer occurrence.

CASE REPORT

In this study, a case of pulmonary embolism in a 6-month-old male infant has been reported. His past history included preterm birth, and severe bronchopulmonary dysplasia, with prolonged oxygen dependency. The positive diagnosis was based on cardiac ultrasound examination, with the direct imaging of a right pulmonary arterial thrombus. Surgical thromboendarterectomy was performed, with a long-term favorable outcome.

CONCLUSION

After excluding from the diagnosis those hemostatic disorders known to be thrombogenic, the most likely hypothesis was retained, i.e., that it was catheter-related. A central venous catheter had been inserted during the neonatal period, and was probably responsible for the embolism. The clinical characteristics and the diagnostic and therapeutic aspects of chronic postembolic cor pulmonale have been discussed in the light of the present findings.
