Application of continuous positive airway pressure in the delivery room: a multicenter randomized clinical trial

This study evaluated whether the use of continuous positive airway pressure (CPAP) in the delivery room alters the need for mechanical ventilation and surfactant during the first 5 days of life and modifies the incidence of respiratory morbidity and mortality during the hospital stay. The study was a multicenter randomized clinical trial conducted in five public university hospitals in Brazil, from June 2008 to December 2009. Participants were 197 infants with birth weight of 1000-1500 g and without major birth defects. They were treated according to the guidelines of the American Academy of Pediatrics (APP). Infants not intubated or extubated less than 15 min after birth were randomized for two treatments, routine or CPAP, and were followed until hospital discharge. The routine (n=99) and CPAP (n=98) infants studied presented no statistically significant differences regarding birth characteristics, complications during the prenatal period, the need for mechanical ventilation during the first 5 days of life (19.2 vs 23.4%, P=0.50), use of surfactant (18.2 vs 17.3% P=0.92), or respiratory morbidity and mortality until discharge. The CPAP group required a greater number of doses of surfactant (1.5 vs 1.0, P=0.02). When CPAP was applied to the routine group, it was installed within a median time of 30 min. We found that CPAP applied less than 15 min after birth was not able to reduce the need for ventilator support and was associated with a higher number of doses of surfactant when compared to CPAP applied as clinically indicated within a median time of 30 min.

Delivery room management of very low birth weight infants in Germany, Austria and Switzerland--a comparison of protocols

Surveys from the USA, Australia and Spain have shown significant inter-institutional variation in delivery room (DR) management of very low birth weight infants (VLBWI, <1500g) at birth, despite regularly updated international guidelines.

Improving the care of preterm infants: before, during, and after, stabilisation in the delivery room

Introduction Up to 10% of infants require stabilisation during transition to extrauterine life. Enhanced monitoring of cardiorespiratory parameters during this time may improve stabilisation outcomes. In addition, technology may facilitate improved preparation for delivery room stabilisation as well as NICU procedures, through educational techniques. Aim To improve infant care 1) before birth via improved training, 2) during stabilisation via enhanced physiological monitoring and improved practice, and 3) after delivery, in the neonatal intensive care unit (NICU), via improved procedural care. Methods A multifaceted approach was utilised including; a combination of questionnaire based surveys, mannequin-based investigations, prospective observational investigations, and a randomised controlled trial involving preterm infants less than 32 weeks in the delivery room. Forms of technology utilised included; different types of mannequins including a CO2 producing mannequin, qualitative end tidal CO2 (EtCO2) detectors, a bespoke quantitative EtCO2 detector, and annotated videos of infant stabilisation as well as NICU procedures Results Manual ventilation improved with the use of EtCO2 detection, and was positively assessed by trainees. Quantitative EtCO2 detection in the delivery room is feasible, EtCO2 increased over the first 4 minutes of life in preterm infants, and EtCO2 was higher in preterm infants who were intubated. Current methods of heart rate assessment were found to be unreliable. Electrocardiography (ECG) application warrants further evaluation. Perfusion index (PI) monitoring utilised in the delivery room was feasible. Video recording technology was utilised in several ways. This technology has many potential benefits, including debriefing and coaching in procedural healthcare, and warrants further evaluation. Parents would welcome the introduction of webcams in the NICU. Conclusions I have evaluated new methods of improving infant care before, during, and after stabilisation in the DR. Specifically, I have developed novel educational tools to facilitate training, and evaluated EtCO2, PI, and ECG during infant stabilisation. I have identified barriers in using webcams in the NICU, to now be addressed prior to webcam implementation.

Impacto de la evolución científico-tecnológica en la Bioética neonatal-perinatal

Resumen: Los avances científico-tecnológicos en neonatología en los últimos 40 años han permitido una importante mejoría en la sobrevida de recién nacidos de extremo bajo peso al nacer, sin embargo la mortalidad neonatal aun representa un porcentaje muy grande de la mortalidad infantil. Esto esta principalmente relacionado a las muertes por prematuridad y sus complicaciones, anomalías congénitas y asfixia perinatal. La mayoría de los recién nacidos son tratados favorablemente en sala de partos y son admitidos a la Unidad de Cuidados Intensivos Neonatales (UCIN). La incertidumbre en el pronóstico de los prematuros extremos en el límite de la viabilidad con alto riesgo de morir en la UCIN o presentar alguna discapacidad, presenta un difícil dilema ético. Se deberá considerar cada caso en forma individual y evaluar el riesgo-beneficio entre las conductas a seguir y el “mejor interés para el niño” y los deseos de los padres que guiarán a decisiones éticas. Diferentes guías de cuidado y variaciones en la práctica médica en los límites de la viabilidad fetal se han descripto dentro y entre países. El objetivo es proveer a los padres una comunicación abierta, directa y transparente con suficiente entendimiento de los factores más relevantes en relación a la situación clínica, el pronóstico y las opciones de tratamiento para que ellos puedan tener una significativa participación en la toma de decisiones. Aceptar que en neonatología, hacer todo lo que uno puede hacer puede ser perjudicial, no útil o beneficioso. No todo lo técnicamente posible es éticamente correcto. El dilema afecta tanto al origen de la vida como a la terminación de la vida.

Challenges of minimizing heat loss at birth: A narrative overview of evidence-based thermal care interventions

Evidence-based thermal care recommendations designed to minimize heat loss immediately at birth are readily available however, hypothermia still persists as a global challenge especially when caring for the most immature and smallest preterm infants. In this narrative overview we aim to provide the reader with a succinct summary of the causes and consequences of hypothermia, the extent of the problem (rates of hypothermia), principles of good thermal care, delivery room preventative measures, the research evidence underpinning existing interventions, current issues in practice, and the way forward. Due to the plethora of research literature available in this subject area, our article will focus primarily on evidence derived from systematic reviews and randomized or quasi-randomized controlled trials assessing the effectiveness of interventions to prevent hypothermia in the most vulnerable (preterm/low birth weight) infants where the intervention or combination of interventions is applied immediately at birth. © 2014.

L’expérience de la maternité des Ouagalaises : d’une génération à l’autre

Ce mémoire porte sur l’expérience de la maternité des Ouagalaises et son évolution. Il s’intéresse au déroulement de la première grossesse, de l’accouchement et de l’entrée en maternité de deux générations de femmes. Privilégiant une approche holistico-inductive en méthodologie qualitative, notre recherche s’est appuyée sur 31 entretiens semi-directifs avec des Ouagalaises, sur 15 d’heures d’observation participante à la maternité ainsi que sur 10 d’entretiens semi-directifs avec des sages-femmes. Les résultats de l’analyse montrent que le savoir de la maternité se transmet toujours de génération en génération, et qu’il demeure encore fortement encadré par les aînées. Toutefois, les transformations en cours dans le système de santé et dans la société burkinabè ne sont pas sans incidence dans la capitale. Les jeunes femmes étant plus renseignées en matière de santé reproductive, elles ont davantage reconnu les signes de la grossesse et le début des douleurs de l’accouchement. Les accompagnantes n’ayant plus accès à la salle d’accouchement et le pouvoir des sages-femmes s’agrandissant, l’expérience de l’accouchement se modifie. Bien que les vieilles femmes n’aient plus le même contrôle sur les parturientes durant l’accouchement, leur influence est toutefois toujours très importante pendant la période post-partum. Les femmes de la jeune génération n’étant généralement pas encore mariées ou installées dans leur propre maison au moment de la grossesse, la promiscuité avec leur belle-mère à l’issue de l’accouchement augmente et le pouvoir de cette dernière est plus important qu’il ne l’était à l’époque de la génération précédente.

Le dispositif institutionnel et la relation thérapeutique en salle d'accouchement : entre le risque, le savoir hégémonique et les rapports de pouvoir.

Ce mémoire vise à établir la complexité de la relation thérapeutique entre l’infirmière et le couple en salle d’accouchement. Sachant que la relation thérapeutique est essentielle à la réussite du processus de soins, sa conceptualisation demeure primordiale pour une meilleure compréhension de son impact et pour mener à bien les soins. Cette recherche ethnographique a voulu documenter les relations des infirmières avec des couples en salle d’accouchement dans un hôpital de l’île de Montréal. Ce mémoire aborde un thème central de l’anthropologie : les relations humaines. La question clef de ce mémoire questionne les facteurs qui entravent et qui favorisent la relation thérapeutique entre l’infirmière et le couple en salle d’accouchement. Cette recherche démontre des lacunes théoriques qui technicisent la relation thérapeutique et indique que la notion du risque, les normes institutionnelles, l’hégémonie du savoir obstétrical et le pouvoir médical sont des facteurs qui semblent avoir une grande influence dans la relation thérapeutique.

Comparación de costo-efectividad entre dos técnicas anestésicas: anestesia con sevofluoraneremifentanil frente a isofluorane-remifentanil

Nos encontramos en la era de la optimización de costos, por lo que es necesario realizar estudios farmacoeconómicos para identificar la costo- efectividad de los anestésicos actuales. Metodología: este estudio prospectivo, cegado al paciente, comparó los costos directos, los tiempos de recuperación y satisfacción de 45 pacientes que se asignaron aleatoriamente a dos grupos de anestesia balanceada (grupo sevofluoraneremifentanil n = 24 o grupo isofluoraneremifentanil n = 21) que iban a ser sometidos a cirugías de otorrinolaringología. Resultados: los tiempos de recuperación temprana (apertura ocular, respuesta a comandos, extubación, orientación y salida de sala) fueron menores en el grupo ISO y tuvieron diferencia estadísticamente significativa. Se encontraron datos variables en los costos de adquisición de los halogenados gastados, que fueron menores para el isofluorane, lo cual hacía también menos costosos los insumos anestésicos durante las cirugías; sin embargo, los costos en la sala de cirugía, en recuperación y sala de ambulatorios y los costos totales no mostraron diferencias significativas. La satisfacción fue similar entre los dos grupos. Conclusiones: una técnica basada en sevofluorane-remifentanil no es más costo-efectiva que utilizar isofluorane-remifentanil para pacientes ambulatorios sometidos a cirugías de otorrinolaringología.

Nascimento de um filho :o significado para o pai

Qualitative study on the meaning of a child s birth to the father. Its general purpose was to comprehend the significance the man attaches to his child s birth and its specific objectives were to identify the man s feelings with regard to his child s birth as well as to verify his attitude toward a child s birth. The study was founded on the theoretical reference system about the man in the gravid-puerperal cycle and the humanization of the assistance. The data were obtained through semistructured interview performed with men accompanying their children s birth whose wives were in the immediate puerperium. This stage occurred in two maternity hospitals in Natal-RN, both of which adopt the principle of safe notherhood in the attendance of women in the process of parturition. The material apprehended from the statements was treated in conformity with the content analysis method in the mode of thematic analysis according to Bardin. Three thematic categories emerged from this process: the father s attitude toward his child s birth, the father s feelings in respect of his child s birth, and the informations received by the father in the course of his child s birth. The speech content was analyzed in accordance with the principles of symbolic interactionism according to Blumer. The results showed that the husbands interact with their respective wives and respond with attitudes of care, help, support, and encouragement within the principles of humanization intermingled with feelings of happiness, restlessness, and suffering leading them to appraise and exalt their consorts. Besides, we verified that the father s attitudes and feelings in the delivery room in the light of symbolic interactionism tend to be influenced by the interaction between him and the attending professionals

Sepsis and Neutropenia in Very Low Birth Weight Infants Delivered of Mothers with Preeclampsia

Objective To study the association between maternal preeclampsia and neonatal sepsis in very low birth weight newborns.Study design We studied all infants with birth weights between 500 g and 1500 g who were admitted to 6 neonatal intensive care units of the Brazilian Network on Neonatal Research for 2 years. Exclusion criteria were major malformations, death in the delivery room, and maternal chronic hypertension. Absolute neutrophil count was performed in the first 72 hours of life.Results A total of 911 very low birth weight infants (preeclampsia, 308; non-preeclampsia, 603) were included. The preeclampsia group had significantly higher gestational age, more cesarean deliveries, antenatal steroid, central catheters, total parenteral nutrition, and neutropenia, and less rupture of membranes >18 hours and mechanical ventilation. Both groups had similar incidences of early sepsis (4.6% and 4.2% in preeclampsia and non-preeclampsia groups, respectively) and late sepsis (24% and 22.1% in preeclampsia and non-preeclampsia groups, respectively). Vaginal delivery and neutropenia were associated with multiple logistic regressions with early sepsis, and mechanical ventilation, central catheter, and total parenteral nutrition were associated with late sepsis. Death was associated with neutropenia in very preterm infants.Conclusions Preeclampsia did not increase neonatal sepsis in very low birth weight infants, and death was associated with neutropenia in very preterm infants.

Antenatal corticosteroid use and clinical evolution of preterm newborn infants

Objectives: To describe the use of antenatal corticosteroid and clinical evolution of preterm babies. Methods: An observational prospective cohort study was carried out. All 463 pregnant women and their 514 newborn babies with gestational age ranging from 23 to 34 weeks, born at the Brazilian Neonatal Research Network units, were evaluated from August 1 to December 31, 2001. The data were obtained through maternal interview, analysis of medical records, and follow-up of the newborn infants. Data analysis was performed with the use of chi-square, t Student, Mann-Whitney, and ANOVA tests and multiple logistic regression, with level of significance set at 5%. Results: Treatment was directly associated with the number of prenatal visits, with maternal hypertension and with the antenatal use of tocolytic agents. Babies from treated pregnant women presented better Apgar scores at the 1st and 5th minute, reduced need for intervention in the delivery room and lower SNAPPE II. They were born with higher birth weight, longer gestational age and needed less surfactant use, ventilation, and oxygenation time. After multiple logistic regression, the use of antenatal corticosteroid independently improved birth conditions, decreased ventilation time, being related to increased occurrence of neonatal sepsis. Conclusions: The use of corticosteroid was associated with better prenatal care and birth conditions, better preterm evolution but higher risk of infection.
