EPEATED INVASIVE PROCEdures occur routinely in neonates who require intensive care, causing pain at a time when it is developmentally unexpected. 1 Neonates are more sensitive to pain than older infants, children, and adults, 2 and this hypersensitivity is exacerbated in preterm neonates. 3 Multiple lines of evidence suggest that repeated and prolonged pain exposure alters their subsequent pain processing, long-term development, and behavior. 4,5 It is essential, therefore, to prevent or treat pain in neonates. Numerous pharmacological and nonpharmacological treatments can alleviate procedural pain in neonates. 6 As a consequence, national 7 and international 6 evidence-based guidelines have been issued for preventing or treating neonatal pain and its adverse consequences. The burden of procedural pain in the neonatal intensive care unit (NICU) has been reported in previous singlecenter studies 8-11 and a multicenter study. 12 The latter study was based on chart review and was not directly observational. Effective strategies to improve pain management in neonates require a better understanding of the epidemiology and management of procedural pain. We report epidemiological data on neonatal pain collected Context Effective strategies to improve pain management in neonates require a clear understanding of the epidemiology and management of procedural pain. Objective To report epidemiological data on neonatal pain collected from a geographically defined region, based on direct bedside observation of neonates.

BackgroundDuring 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.MethodsProspective 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.ResultsData 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.ConclusionsAt 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.

BackgroundThe 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.MethodsThe 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.FindingsQualitative 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.InterpretationParents 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.

We identified SPOCK2 as a new possible candidate susceptibility gene for bronchopulmonary dysplasia. Its lung expression pattern points toward a potential role in alveolarization.

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.

Premature lungs are highly susceptible to lung injuries, leading to bronchopulmonary dysplasia (BPD). Keratinocyte growth factor (KGF) is produced by the developing lung and may reduce the risk of BPD by preventing injury to the lung epithelium and enhancing its repair. To determine whether KGF concentrations in the airways during the initial phase of hyaline membrane disease are correlated with subsequent development of BPD defined as the need for supplemental oxygen at a postconceptional age of 36 weeks, we obtained tracheal aspirates within 3 hours of birth (Day 0) from 91 intubated neonates with a gestational age of 30 weeks or less. Repeat samples were obtained from 42 neonates within 5 days after birth. KGF in aspirate supernatants was measured by enzyme-linked immunosorbent assay. On Day 0, KGF was detected in all but six neonates. A significant increase in KGF concentration was found from the first to the second samples. The highest KGF concentration within 5 days after birth (KGF(max)) was significantly higher in survivors without BPD than in those with BPD. A KGF(max) value higher than 110 pg/ml had a positive predictive value of 95% for absence of BPD. KGF may hold promise for the treatment of very premature neonates.

2002.-Matrix-degrading metalloproteinases may play a role in the pathophysiology of bronchopulmonary dysplasia (BDP). We, therefore, evaluated correlations between gelatinase activities [metalloproteinase (MMP)-2 and MMP-9] or tissue inhibitor of metalloproteinase (TIMP)-1 levels present in the airways during the initial phase of hyaline membrane disease and the onset of BPD. Tracheal aspirates were obtained within 6 h of birth (day 0) from 64 intubated neonates with a gestational age Յ30 wk. Forty-five neonates were resampled on day 3 or 5. Total MMP-2 level measured by zymography fell with time, whereas total MMP-9 level and TIMP-1 levels, assayed by ELISA, increased; the MMP-9 increase correlated with the increase in airway inflammatory cell numbers. Among the parameters measured on day 0, 3, or 5, lower total MMP-2 level, lower birth weight, and higher fraction of inspired oxygen on day 0 were significantly and independently associated with the development of BPD. In conclusion, MMP-9 level and TIMP-1 levels increased after birth but are not linked to BPD outcome. In contrast, low MMP-2 level at birth is strongly associated with the development of BPD. metalloproteinase; lung development; newborn; extracellular matrix PREMATURE NEONATES WITH HYALINE membrane disease are at risk of developing bronchopulmonary dysplasia (BPD), as a sequel of both the disease and its treatment. The pathogenesis is unclear, but BPD is thought to result from damage to an immature lung. Mechanical ventilation, oxygen therapy, and airway inflammatory responses have all been implicated in the development of BPD (19). These insults appear to interfere with normal lung maturation, which is incomplete at birth. In particular, they appear to alter alveolar formation, on the basis of morphometric studies of severe BPD (3, 24). Alveolar formation is characterized by the multiplication of alveolar septa and the thinning of interalveolar walls, both of which require intense remodeling of the pulmonary extracellular matrix (4). Changes in matrix turnover have been experimentally linked to abnormal alveolar formation (20). The proteinase-antiproteinase balance in the lung is a key factor in harmonious matrix turnover. In particular, matrix metalloproteinases (MMPs), which can synergistically digest the major macromolecules of connective tissue matrices, have been implicated in physiological regulation of lung growth. The MMP gelatinase A (MMP-2) has been shown to play a role in the major collagen turnover that occurs during early postnatal rat lung growth (1, 2). We postulated that MMP-2 might also participate in human lung development and that inadequate MMP-2 levels in premature lungs exposed to insults could contribute to impaired lung growth and thus to BPD. We also postulated that MMPs may be secreted in excess during the inflammatory response associated with hyaline membrane disease and may, therefore, lead to tissue degradation. Gelatinase B (MMP-9) is the main MMP released by inflammatory cells such as neutrophils and alveolar macroph...
