French national survey on simulation-based neonatology education of pediatric residents.

The French Society of Neonatology (SFN) conducted a national questionnaire survey on the simulation-based education neonatal curriculum for pediatric residents. The response rate was 93% for the pediatric curriculum coordinators and 97% for the neonatal intensive care unit medical directors and neonatal transport teams. The average hourly volume during the curriculum was 21 ± 17 h. Overall, 89% of regional pediatric curricula offered at least one simulation session. Each simulation program involved newborn resuscitation in the delivery room but often lacked a formalized program. Additionally, half of the neonatology departments provided simulation-based education. Simulation education is now common for training pediatric residents in neonatology in France but it is heterogeneous in the French territory.

[Human Resources for Unplanned Activities in Obstetrics and Gynecology. Consensus statements by the CNGOF, CARO, CNSF, FFRSP, SFAR, SFMP and SFN]. / Ressources humaines pour les activités non programmées en gynécologie-obstétrique. Propositions élaborées par le CNGOF, le CARO, le CNSF, la FFRSP, la SFAR, la SFMP et la SFN.

OBJECTIVE: To determine a minimum threshold of human resources (midwives, obstetricians and gynecologists, anesthesiology and intensive care units, pediatricians) to ensure the safety and quality of unplanned activities in Obstetrics and Gynecology. MATERIALS AND METHODS: Consultation of the MedLine database, the Cochrane Library and the recommendations of authorities. Meetings of representative members in different modes of practice (university, hospital, liberal) under the aegis of and belonging to the French College of Obstetricians and Gynecologists (CNGOF), the French Society of Anesthesia and Resuscitation (SFAR), the French Society of Neonatalogy (SFN), the French Society of Perinatal Medicine (SFMP), the French College of Midwives (CNSF), the French Federation of Perinatal Care Networks (FFRSP) with elaboration of a re-read text by external experts, in particular by the members of the Boards of Directors of these authorities and of Club of Anesthesiology-Intensive Care Medicine in Obstetrics (CARO). RESULTS: Different minimum thresholds for each category of caregivers were proposed based on the number of births/year. These proposed minimum thresholds can be modulated upwards according to the types (level I, IIA, IIB or III) or the activity (existence of an emergency reception service, maternal-fetal and/or surgical activity of resort or referral). Due to peak activity and the possibility of unpredictable concomitance of urgent medical procedures, it is necessary that organizations plan to use resource persons. The occupancy rate of the target beds of a maternity ward must be 85%. CONCLUSION: These proposed minimum thresholds are intended to help caregivers providing non-scheduled perinatal as well as Obstetrics and Gynecology care to make the most of the human resources allocated to institutional bodies to ensure their safety and quality.

[Delivery room management: What's new in 2010 recommendations?]. / Réanimation du nouveau-né en salle de naissance : qu'apportent les recommandations de 2010 ?

For apneic or bradycardic babies born at term, it is best to begin ressuscitation in the delivery room with air rather than 100% oxygen. Administration of supplementary oxygen should be regulated by blending oxygen and air, and the concentration delivered should be guided by oximetry. Preterm babies less than 32 weeks gestation may not reach the same arterial blood oxygen saturations in air as those achieved by term babies. Therefore, blended oxygen and air should be given guided by pulse oximetry. Detection of exhaled carbon dioxide in addition to clinical assessment is recommended as the most reliable method to confirm placement of a tracheal tube in neonates. If presented with a floppy, apnoeic baby born through meconium, it is reasonable to rapidly inspect the oropharynx to remove potential secretions. Tracheal intubation and suction may be useful. Therapeutic hypothermia should be considered for infants born at term or near-term with evolving moderate to severe hypoxic-ischemic encephalopathy, with protocol and follow-up coordinated through a regional perinatal system. For preterm babies of less than 28 weeks gestation delivery room temperatures should be at least 26 °C. They should be completely covered in a food-grade plastic bag up to their necks, without drying, immediately after birth. If the heart rate of a newly born baby is not detectable and remains undetectable for 10 min, it is then appropriate to consider stopping resuscitation. Simulation should be used as a methodology in resuscitation education.

[Implementing palliative care for newborns in various care settings. Part 3 of "Palliative care in the neonatal period"]. / La mise en oeuvre pratique des soins palliatifs dans les différents lieux de soins : 3(e) partie des réflexions et propositions autour des soins palliatifs en période néonatale.

Palliative care in newborns may take place in the delivery room and then continued either in maternity wards or in the neonatal unit. For babies developing a chronic condition, going home may be advantageous. The population concerned includes babies born with a severe intractable congenital malformation and certain extremely preterm newborn babies at the limits of viability. Care procedures as well as withholding and withdrawing treatments are reviewed.

[Fetomaternal hemorrhage caused by intraplacental choriocarcinoma]. / Hémorragie foetomaternelle sur choriocarcinome placentaire.

A male infant was born at 41 weeks' gestation to a 34-year-old primiparous woman after an uneventful pregnancy. Physical examination showed extreme paleness. Fetal hemoglobin was 7.6g/dl and Kleihauher exam revealed fetomaternal hemorrhage. Pathology revealed in situ intraplacental choriocarcinoma. Serum human chorionic gonadotrophin level was undetectable 1 month after the delivery both in woman and in newborn. We suggest that a pathological examination of the placenta should be performed in any case of fetomaternal hemorrhage in order to avoid misdiagnosis of intraplacental choriocarcinoma.

Clinical application of fetal urine production rate in unexplained polyhydramnios.

OBJECTIVE: To evaluate the clinical use of hourly fetal urine production rate (HFUPR) in polyhydramnios. METHODS: This was a retrospective review of 33 singleton pregnancies with polyhydramnios, 30 of them unexplained and three due to gastrointestinal atresia. HFUPR was estimated using three-dimensional ultrasound and was compared with recently established nomograms. Abnormal midterm outcome, defined as diagnosis or persistence of pathology after the neonatal period until the age of 2 years, was analyzed according to prenatal HFUPR measurements and other polyhydramnios characteristics. RESULTS: Seventeen of the 30 fetuses with unexplained polyhydramnios had an HFUPR above the 95(th) centile, and five (29.4%) of them developed midterm disorders. None of the 13 with normal HFUPR developed midterm disorders. The HFUPR was 1.9 (SD, 0.7) multiples of the median (MoM) in fetuses with an adverse childhood outcome and 1.4 (SD, 1.2) in fetuses with normal childhood outcome (P = 0.34). In the three fetuses with gastrointestinal atresia, the HFUPR was significantly lower than in those with unexplained polyhydramnios (P = 0.003). CONCLUSION: HFUPR was associated with the mechanism of polyhydramnios but failed to help in the prognosis of unexplained polyhydramnios because of lack of power. Children with prenatal unexplained polyhydramnios and HFUPR above the 95(th) centile should nevertheless receive detailed pediatric follow-up.

[Management of antenatal fetal abdominal tumors. Clues for the diagnosis of a congenital mesoblastic nephroma]. / Conduite à tenir obstétricopédiatrique devant la découverte anténatale d'une masse hyperéchogène rétropéritonéale. Arguments en faveur d'un néphrome mésoblastique congénital.

The prenatal diagnosis of abdominal mass poses the problem of its origin. Renal tumors are rarer than neuroblastoma but they are most often congenital mesoblastic nephroma. The congenital mesoblastic nephroma has a good forecast in spite of a sonographic impressive aspect. MRI can help to locate tumor but cannot tell difference between the different kinds of renal tumor. Prenatal forecast is especially linked with hydramnios and hydrops fetalis. Histolological study of the tumor is important for the prognosis. Two morphological subtypes are currently distinguished: the classic type with a good forecast and the atypical or cellular type. Distant metastases have been related only to the cellular form but especially in infants aged more than 3 months and never in the newborns. The diagnosis of the tumor does not change the mode of delivery except in case of an important volume. Complications are searched during the first days of life: hypertension, hypercalcemia, vomiting, hyperreninemia. Radical nephrectomy is performed after the end of the first week. In case of a classic form, the healing is always obtained. In case of cellular form, distant metastases are searched. In any rate, the follow-up is recommended until the end of the growth.

[Air or oxygen for neonatal resuscitation in the delivery room?]. / Air ou oxygène pour le nouveau-né en salle de naissance?

Most of the contemporary guidelines on newborn resuscitation are based on experience but lack scientific evidence. The use of 100% oxygen is one of the more evident. Today, these practices are questioned, particularly for the resuscitation of moderately depressed full term or near term newborns. Results of recent meta-analysis of trials that compared ventilation with air versus pure oxygen at birth suggests current practices should be revisited. On the basis of these data, air can be the initial gas to use for these babies. Large scale trials, including preterm and cause and/or severity of initial asphyxia, must now be undertaken before the publication of new guidelines for these populations. Particularly severely asphyxiated infants might require supplemental oxygen with titration of oxygen delivery and continuous monitoring of oxygen saturation.

[Cardiorespiratory arrest in full term newborn infants: six case reports]. / Malaises graves et morts subites après une naissance normale à terme: à propos de six cas.

Cardiorespiratory arrest occurring within the first two hours of life of a perfectly normal newborn is a very seldom event hitherto unreported. Six infants born after an uneventful pregnancy by normal vaginal delivery, with a normal Apgar score and physical examination, were found with unexpected cardiorespiratory arrest requiring cardiac and respiratory resuscitation early after birth. All were lying in the prone position, their face covered up while facing mother's abdomen, breast or neck. All mothers were primipara. All newborns but one died. Biological and bacteriological samples were normal and early onset neonatal sepsis was ruled out. Autopsy, performed in five infants, was not contributive. We hypothesize that the sudden and unexpected cardiorespiratory arrest occurring in these normal newborns was secondary to acute upper airway obstruction. To prevent this life threatening post-natal asphyxic episode, it is essential to ensure that the face of a newborn lying down upon mother's breast and abdomen is properly and continuously cleared.

Emergence of nosocomial Pseudomonas aeruginosa colonization/infection in pregnant women with preterm premature rupture of membranes and in their neonates.

The epidemiology, risk factors, maternal and neonatal outcomes of nosocomial Pseudomonas aeruginosa acquisition in preterm premature rupture of membranes were analysed. Of 63 women receiving antibiotic prophylaxis with co-amoxiclav, 11 acquired P. aeruginosa vaginal carriage with a median delay of 15 days (6-42) i.e. an incidence of 8.94 per 1000 days of expectant management. Five neonates born to 11 positive mothers were colonized or infected, three of whom died of fulminant sepsis. The duration of antibiotic treatment and multiple pregnancy were identified as independent risk factors. The epidemiological investigation revealed a vertical transmission between mothers and neonates, and suggested selective pressure of antibiotic treatment.

Perinatal factors affecting survival and survival without disability of extreme premature infants at two years of age.

OBJECTIVE: To study obstetrical factors leading to very preterm delivery (between 24 and 28 weeks) and to relate these factors to neonatal outcome and psychomotor development at two years. STUDY DESIGN: Among 144 infants born alive before 28 weeks of gestation at a single perinatal center between January 1993 and December 1996, we analyzed the influence on neonatal outcome and on psychomotor development at 24 months of a variety of perinatal and neonatal factors. Psychomotor development at two years was classified as: normal, borderline, or moderately or severely handicapped. RESULTS: During the study period, 114 women delivered live infants before 28 weeks' gestation: 87 singletons, 25 sets of twins, 1 set of triplets and 1 set of quadruplets. All 144 live-born infants received neonatal resuscitation: 50 died before discharge. At two years of age, 6 of the 94 survivors were lost to follow-up. Assessments of the psychomotor development of the other 88 was normal for 52%; borderline for 20%, moderately handicapped for 20%, and severely handicapped for 8%. Multivariate analysis found that two factors affected survival: birthweight and fetal heart rate. (The 42% of infants with a birthweight below 700 g survived versus 83% above 900 g, P<0.001, OR=5.2, 95% CI (confidence interval) [2.4-11.2].) CONCLUSION: These data show the influence of perinatal factors on the outcome of very preterm infants; birthweight and fetal heart rate are strongly correlated with survival. Gestational age is a good predictor of psychomotor development at two years.

[Growth discordance in dichorionic twin pregnancies: risk factors, diagnosis and management]. / Conflits d'intérêt prénatals entre les jumeaux. Discordance de croissance foetale des jumeaux bichoriaux: facteurs de risque, diagnostic et prise en charge.

OBJECTIVE: To analyse the risk factors and perinatal consequences of growth discordance among dichorionic twin pregnancies. Subjects and methods. A cohort of 346 dichorionic twin pregnancies delivered at one institution between January 1996 and December 1999 was analyzed. Two groups were compared, according to the presence or absence of growth discordance (n=72 and 274, respectively). Birth weight discordance was defined as a difference of 20% or more of the weight of the heavier twin, associated with an intra-uterine growth restriction (10(th) percentile) of at least one twin. Ultrasound discordance was defined as a difference of estimated fetal weight>20%. The two groups were compared by univariate and multivariate analysis. RESULTS: The main risk factors for birth weight discordance in multivariate analysis were ovulation induction (OR=1.6 [1.0-2.4]), multifetal pregnancy reduction (OR=2.3 [1.3-4.2]), and fetal malformations (OR=2.4 [1.0-5.4]). Ultrasound shows a poor performance in predicting discordance with a sensitivity of 55.6%, a specificity of 94.2%, a positive predictive value of 71.4% and a negative predictive value of 89.0%. Birth weight discordance was associated with a poor fetal and neonatal outcome: gestational age at delivery was 34.4 weeks versus 35.4 weeks, there were more caesarean deliveries (OR=1.9 [1.3-2.8]), a higher perinatal mortality (OR=3.7 [1.6-8.5]), and more neonatal intensive care unit admissions (OR=1.8 [1.2-2.7]). Multivariate analysis shows that growth discordance is an independent risk factor for mortality but not for cerebral adverse outcome or respiratory distress syndrome. CONCLUSION: Ovulation induction and multifetal pregnancy reduction are independent risk factors for twin birth weight discordance, which carries a poor perinatal prognosis.

[Accompanying babies to death after late termination of pregnancy]. / Accompagnement au décès postnatal dans le cadre de l'interruption tardive de grossesse.

When feticide, necessary within the framework of late termination of pregnancy, cannot be achieved before delivery for medical reasons or because the act is refused by the parents, we propose as an alternative, to accompany the baby to death in the neonatology unit. This approach can be seen as palliative care despite the ethical and legal issues it raises. It can be an appropriate response to the parents' distress when moral and religious beliefs are contradicted by medical reality. This situation remains exceptional and must be envisaged case by case. The decision to institute the principle of accompanying babies to death was made after open discussion conducted for many years among neonatologists. The final decision cannot however be made until the obstetrical and pediatric teams have reached a sufficient degree of reciprocal confidence.

[Anoxic encephalopathy of the term neonate and brain hypothermia]. / Encéphalopathie anoxique du nouveau-né à terme et hypothermie cérébrale.

The outcome of term newborns with birth asphyxia and moderate to severe hypoxic ischemic encephalopathy remains very poor. After the primary phase of energy failure during asphyxia, neuronal cell metabolism may deteriorate in a secondary phase of brain injury. The window between these two phases opens the way to potential neuroprotective treatments such as brain cooling. Promising experimental data on controlled hypothermia need to be examined with clinical trials.

Single blood donor exposure programme for preterm infants: a large open study and an analysis of the risk factors to multiple donor exposure.

UNLABELLED: As the need for blood transfusions of very preterm infants remains considerable, various strategies are considered to minimize exposure to multiple blood donors along with blood wastage. In a large population of very preterm infants born between 24 and 31 weeks' gestation, we undertook an open study to assess the efficacy of a single blood donor exposure programme and to determine, among the population enrolled in this programme, the risk factors for exposure to multiple donors. One hundred and forty-two neonates were included in a single donor exposure programme with a 35-day expiry date blood unit. Though no inflation in the total number of transfusions was noticed, there was a 55% overall reduction in the total number of required donors. To determine the risk factors for exposure to multiple donors in this population, 114 neonates alive after the expiry date of the first unit of packed red blood cells were selected. The greatest and the most extending transfusion requirements were observed in very preterm infants born before 28 weeks' gestation and in those born after but with an intra-uterine growth retardation below the 10th percentile. Indeed, 70% of those high-risk infants were exposed to a second blood donor and more than 85% of the group exposed to a second donor belonged to this high-risk population. CONCLUSION: Neonates with a very high risk of a more-than-one donor exposure were born before 28 weeks' gestation or between 28 and 31 weeks but with an intra-uterine growth retardation below the 10th percentile.

The early diagnosis of periventricular leukomalacia in premature infants with positive rolandic sharp waves on serial electroencephalography.

OBJECTIVE: The objective of this study was to determine the specificity and the sensitivity of electroencephalography's positive rolandic sharp waves (PRSW) for the diagnosis of cystic and noncystic periventricular leukomalacia (PVL). METHODS: A retrospective study was performed on a population of 765 premature infants alive after 5 days who were divided into two groups; 166 infants born before 28 weeks (group 1) and 599 born between 28 and 32 completed weeks' gestation (group 2). Each infants underwent repeated ultrasound scanning and electroencephalography recordings during the first weeks of life. Magnetic resonance imaging was performed in infants with persisting hyperechoic periventricular densities on ultrasonography. RESULTS: A total of 83 (10.8%) newborns had PVL; 65 (8.5%) had cystic PVL PRSW, observed in 55 (7.2%) infants, always preceded the ultrasonic detection of cysts. PRSW were very specific markers of PVL in both groups (100% in group 1, 99.8% in group 2). PRSW sensitivity was found dependent on gestational age: 32.4% in group 1 in contrast to 87.8% in group 2. CONCLUSION: PRSW are an early and very specific marker of PVL in premature infants.

Are neonatal brain lesions due to intrauterine infection related to mode of delivery?

Studies of antenatal and intrapartum factors involved in the development of cerebral palsy have identified intrauterine infection and chorioamnionitis as high risk situations for white matter damage, especially periventricular leukomalacia. To characterise adverse or protective perinatal factors further, we undertook a multiple regression analysis of selected perinatal events in a population of 110 inborn premature neonates with documented chorioamnionitis. In the total population of 110 infants delivered at between 25 and 32 weeks, 101 (92%) survived the first week of life and two were subsequently excluded. Of the 99 remaining infants, 20 (20%) developed periventricular leukomalacia including 16 (80%) cystic lesions. Forty-five (45%) babies were born by lower segment caesarean section, and for 37 of these, this was carried out before labour. Fetal presentation at delivery was breech in 14 (26%) of those born vaginally and 23 (52%) of those born by lower segment caesarean section (OR 3 [95% CI 1.3-7]). Among predetermined perinatal risk factors for periventricular leukomalacia, logistic regression analysis showed that delivery by caesarean section was associated with a dramatic decrease in the incidence of periventricular leukomalacia (OR 0.15 [95% CI 0.04-0.57]). These preliminary results warrant confirmation and preferably a prospective study before considering caesarean section as a protective perinatal factor of periventricular leukomalacia.
