[And if it happened to children? Adapting medical care during terrorist attacks with multiple pediatric victims]. / Et si c'était des enfants ? Adaptation de la prise en charge médicale en cas d'attentats terroristes avec de nombreux enfants victimes.

In light of the recent terrorist attacks in Europe, we need to reconsider the organization of rescue and medical management and plan for an attack involving multiple pediatric victims. To ensure quick surgical management, but also to minimize risk for on-site teams (direct threats from secondary terrorist attacks targeting deployed emergency services), it is crucial to evacuate patients in a swift but orderly fashion. Children are vulnerable targets in terrorist attacks. Their anatomical and physiological characteristics make it likely that pediatric victims will suffer more brain injuries and require more, often advanced, airway management. Care of multiple pediatric victims would also prove to be a difficult emotional challenge. Civilian medical teams have adapted the military-medicine principles of damage control in their medical practice using the MARCHE algorithm (Massive hemorrhage, Airway, Respiration [breathing], Circulation, Head/Hypothermia, Evacuation). They have also learned to adapt the level of care to the level of safety at the scene. Prehospital damage control principles should now be tailored to the treatment of pediatric patients in extraordinary circumstances. Priorities are given to hemorrhage control and preventing the lethal triad (coagulopathy, hypothermia, and acidosis). Managing hemorrhagic shock involves quickly controlling external bleeding (tourniquets, hemostatic dressing), using small volumes for fluid resuscitation (10-20ml/kg of normal saline), quickly introducing a vasopressor (noradrenaline 0.1µg/kg/min then titrate) after one or two fluid boluses, and using tranexamic acid (15mg/kg over 10min for loading dose, maximum 1g over 10min). Prehospital resources specifically dedicated to children are limited, and it is therefore important that everyone be trained and prepared for a scene with multiple pediatric patients.

[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.

Mortality in out-of-hospital premature births.

AIM: To determine whether the mortality for out-of-hospital (OOH) premature births was higher than for in-hospital premature births and identify additional risk factors. PATIENTS AND METHODS: A historical cohort study of a consecutive series of live-born, OOH, births of 24-35 weeks gestation cared for by two Transport Teams working in and around Paris, France 1994-2005. Matching with in-hospital births was according to gestational age, antenatal steroid use, the mode of delivery and nearest year of birth. RESULTS: Eighty-five OOH premature births were identified, of whom 83 met inclusion criteria, and 132 matching in-hospital premature births were selected. There was 18% mortality in the OOH group compared with 8% for the in-hospital group [p = 0.04, OR 2.9, (CI 95% 1.0-8.4)]. Variables significantly associated (p < 0.05) with the OOH birth were HIV infection, lower maternal age and endo-tracheal intubation, lack of medical follow-up during pregnancy, low temperature and low birth weight. CONCLUSIONS: Mortality was more than twice as high in out-of-hospital deliveries than for in-hospital matched controls. Hypothermia was an important associated risk factor. Measures such as oxygen administration to maintain an appropriate saturation for gestational age, the provision of polyethylene plastic wraps and skin-to-skin contact are recommended.

[National evaluation of knowledge and practice of cardiopulmonary resuscitation of children and infants in the field]. / Prise en charge préhospitalière de l'arrêt cardiaque de l'enfant et du nourrisson: enquête nationale de pratique.

INTRODUCTION: After the publication of new recommendations for cardiopulmonary resuscitation (2005 guidelines and 2006 French recommendations), we conducted a study amongst EMS teams concerning their approach with children and infants, nationwide. The objective was to measure the level of knowledge of guidelines and practice. METHODS: The online questionnaire was offered to emergency physicians belonging to the French emergency database, between November 1st and December 15th 2007. Incomplete questionnaires were excluded from the study. We recorded: profile of personnel, knowledge of guidelines, basic CPR and advanced CPR parameters. RESULTS: Four hundred and thirty-nine questionnaires were analyzed. Personnel was aged under 40 in 50.2 %, with 2-5 years experience in prehospital emergency care (57.6 %); 51,3 % declared having had training in pediatric CPR. A minority of subjects declared knowing the 2005 Guidelines (35 %), more the French 2006 recommendations (62.5 %). Basic CPR: transition age child/adult known in 30.3 %. Compression/ventilation ratio: 30/2 for one rescuer in 50.2 % (child), 46.5 % (infant); 15/2 for two or more rescuers in 57.6 % (child), 48 % (infant). AED age for use (1 year old) known in 59.8 %. Advanced CPR: epinephrine dose known in 89.3 % (intravenous) and 34.3 % (tracheal). External shock known in 57.2 %. CONCLUSION: This study emphasizes the lack of knowledge, especially with regard to first aid. Formations will be developed.

Ventricular fibrillation and defibrillation.

Cardiac arrest in children is not often due to a disturbance in rhythm that is amenable to electrical defibrillation, contrary to the situation in adults. When a shockable rhythm is present, defibrillation using an external electric shock applied at an early stage after pre-oxygenation and chest compressions is of proven efficacy. Success at conversion of ventricular fibrillation is dependent on the delay before delivering the shock and defibrillation efficiency, which is itself a function of thoracic impedance, energy dose and waveform.

[Newborn asphyxia at term during delivery]. / Volume de recrutement, charge de travail et morbidité liés aux asphyxies per-partum à terme pour les services mobiles d'urgence et de réanimation (SMUR) pédiatriques.

UNLABELLED: Recruitment, work load and morbidity linked to newborn asphyxia during delivery at term: a study from Pediatric Mobile Intensive Care Units. OBJECTIVE: In a population of term neonates transported by the mobile intensive care units (MICU), we aimed to determine the incidence of neonates with anoxic-ischemic encephalopathy related to asphyxia, to analyze in this population the difficulties of management, and to try to identify which of these newborns require new therapeutic strategies. METHODS: This retrospective study was performed over a 2-year period (2000 and 2001) in 3 paediatric MICU from the Ile de France area. During this period, 7,648 infants were transported including 3,301 newborns of more than 36 weeks of gestational age and less than 72 hours of life. These neonates came from 73 different hospitals. Among these 3,301 infants, 237 neonates (124 boys and 113 girls) with anoxic-ischemic encephalopathy related to asphyxia were selected in the present study. Inclusion criteria were association of one obligatory criterion of fetal distress during delivery and at least one criterion of neonatal asphyxia or one criterion of anoxic-ischemic encephalopathy. Data were compiled and analyzed with Epidata package and Epi info package, respectively. RESULTS: These 237 neonates with anoxic-ischemic represented 12% of MICU activity at the same gestational and postnatal ages. The mean gestational age was 39.5 + 1.5 weeks. The mean birth weight was 3,188 + 559 g. More than 50% of these neonates were born in level I maternities. Fifty-three percent of the infants were born by caesarean section. Eighty-three percent of the neonates had an Apgar score at 1 minute <3. Eighty-eight percent of the neonates received resuscitation care at 5 minutes of life and 34% of these had an Apgar score at 10 minutes <5. In 50% of the cases, the MICUs arrived at the maternity of delivery within 1 h 45 min of life and transportation of the neonates was completed after 3 hours of life. The neonates were transported to an intensive care unit in 88% of the cases (half to a polyvalent intensive care unit and half to a neonatal intensive care unit). Forty-four percent of transported neonates had no encephalopathy, 30% had a severe encephalopathy or seizures, 27% had multiple organ failure. Mortality reached 28% and encephalopathy accounted for two thirds of these deaths. Neonates who arrived in pediatric care units after 3 hours of life had more severe morbidity than neonates who arrived before 3 hours of life. CONCLUSION: Pediatric MICUs transport the most severely affected neonates. The initial clinical state is critical, and systemic and neurological complications are frequent and severe. Calls to the MICU should be made earlier in order to enable a better impact of new neuroprotective strategies.

[Severe bacterial infections in children. Survey by the pediatric mobile intensive care unit AP/HP in the Ile-de-France area]. / Infections bactériennes graves de l'enfant. Enquête des SMUR pédiatriques AP/HP de l'Ile-de-France (de 1998 au 1er quadrimestre 2001).

This study involves 106 infants (neonatal period ruled out), victims of severe bacterial infections managed from 1st january 1998 to 30 April 2001 by the four paediatric Mobile Intensive Care Unit (P.M.I.C.U.) teams AP-HP in Ile-de-France area. 46.2% of the whole infants are primary interventions (home, medical room, airport) and primary-secondary interventions (hospital emergencies) whereas 53.8% are related to secondary transports of infants who have been hospitalized and suffered from severe bacterial disorders complicating their original disease. 51% are meningitidis infections, rather due to streptococcus pneumoniae and meningococcis, associated with severe infectious purpura. 20.75% are toxic shock syndromes in patients suffering from chronic affections (sickle cell anemia), acquired or congenital immunodeficiencies; 19.8% of the cases are severe bacterial pneumonia (staphylococcal pleuro-pneumopathies, bordetella pertussis cough) or surinfected viral infections (VRS bronchiolitis, pneumonia due to mycoplasma pneumoniae and para-influenzae III). Authors study various characteristics of the two patient's groups, their immediate management by local medical team and by the P.M.I.C.U. team, their early term outcome. 65% of children recovered apparently without sequelae, 19% died, and 16% healed but with significant sequelaes, notably neurological damage. Meningitidis due to Streptococcus pneumoniae are particularly severe, because of their prognostic (10 deaths, 8 severe sequelae among the 26 cases). These observations prompted us to recommend early immunization of infants at 2-3 months post natal age by the new vaccine conjugated up to 7 valences such as "Prevenar". If this vaccine have been available for this patient series, may be avoided 8 deaths, 7 severe sequelae, with 1 septic shock syndrome due to streptococcus pneumoniae and another serious infection in a homozygous sickle cell disease.

[Intraosseous device of perfusion. Apropos of 3 cases before hospitalization]. / Dispositif intraosseux de perfusion. A propos de trois observations en préhospitalier.

A renewal of interest in the intraosseous route has appeared lately in France. It concerns pediatric patients. After anatomophysiological and technical quotes, we report the indications, contraindications, method of supervision and complications of the placement of an intraosseous infusion. Our modest experience enables us to present three observations where intraosseous route has been used outside hospital in children suffering a cardiopulmonary arrest on arrival of the practitioner belonging to the mobile emergency unit. This rapid and easy to place technique seems to be attractive as an alternative to the intravenous route in situations of utmost emergency, this all the more so since there are few reported contraindications and complications.
