ABSTRACT

OBJECTIVE: To assess whether oxytocin administered before clamping the umbilical cord modifies the volume of placental transfusion. DESIGN: Randomised controlled trial. METHODS: Mothers of term infants born vigorous by vaginal delivery with informed consent provided in early labour were randomly assigned to oxytocin (10 IU) given intravenously within 15 s of birth (group 1) or after clamping the umbilical cord 3 min after delivery (group 2). Soon after birth, all infants were weighed using a 1 g precision scale and subsequently placed on the mother's abdomen or chest. At 3 min, in both groups, the cord was clamped and cut, and the weight was again obtained. The primary outcome (volume of placental transfusion) was estimated by the difference in weights. RESULTS: 144 patients were included. There were no differences in the primary outcome: infants in group 1 (n=70) gained a mean weight of 85.9 g (SD 48.3), and in group 2 (n=74) 86.7 g (SD 49.6) (p=0.92). No differences were found in secondary outcomes, including newborns' haematocrit and bilirubin concentrations and severe maternal postpartum haemorrhage. On the advice of the Data and Safety Monitoring Committee, the trial was stopped due to futility at 25% of the planned sample size. CONCLUSIONS: When umbilical cord clamping is delayed for 3 min, term newborn infants born vigorous receive a clinically significant placental transfusion which is not modified by the administration of intravenous oxytocin immediately after birth. TRIAL REGISTRATION NUMBER: NCT02618499.

ABSTRACT

BACKGROUND: Premature birth is a growing and serious public health problem affecting more than one of every ten infants worldwide. Bronchopulmonary dysplasia (BPD) is the most common neonatal morbidity associated with prematurity and infants with BPD suffer from increased incidence of respiratory infections, asthma, other forms of chronic lung illness, and death (Day and Ryan, Pediatr Res 81: 210-213, 2017; Isayama et la., JAMA Pediatr 171:271-279, 2017). BPD is now understood as a longitudinal disease process influenced by the intrauterine environment during gestation and modulated by gene-environment interactions throughout the neonatal and early childhood periods. Despite of this concept, there remains a paucity of multidisciplinary team-based approaches dedicated to the comprehensive study of this complex disease. METHODS: The Discovery BPD (D-BPD) Program involves a cohort of infants < 1,250 g at birth prospectively followed until 6 years of age. The program integrates analysis of detailed clinical data by machine learning, genetic susceptibility and molecular translation studies. DISCUSSION: The current gap in understanding BPD as a complex multi-trait spectrum of different disease endotypes will be addressed by a bedside-to-bench and bench-to-bedside approach in the D-BPD program. The D-BPD will provide enhanced understanding of mechanisms, evolution and consequences of lung diseases in preterm infants. The D-BPD program represents a unique opportunity to combine the expertise of biologists, neonatologists, pulmonologists, geneticists and biostatisticians to examine the disease process from multiple perspectives with a singular goal of improving outcomes of premature infants. TRIAL REGISTRATION: Does not apply for this study.

ABSTRACT

BACKGROUND: Delayed cord clamping allows for the passage of blood from the placenta to the baby and reduces the risk of iron deficiency in infancy. To hold the infant for more than 1 min at the level of the vagina (as is presently recommended), on the assumption that gravity affects the volume of placental transfusion, is cumbersome, might result in low compliance, and interferes with immediate contact of the infant with the mother. We aimed to assess whether gravity affects the volume of placental transfusion METHODS: We did a multicentre non-inferiority trial at three university-affiliated hospitals in Argentina. We obtained informed consent from healthy mothers with normal term pregnancies admitted early in labour. Vigorous babies born vaginally were randomly assigned in a 1:1 ratio by computer-generated blocks and sequentially numbered sealed opaque envelopes to be held for 2 min before clamping the umbilical cord, at the level of the vagina (introitus group) or on the mother's abdomen or chest (abdomen group). Newborn babies were weighed immediately after birth and after cord clamping. The primary outcome was the difference in weight (as a proxy of placental transfusion volume). The prespecified non-inferiority margin was 18 g (20%). We used t test and χ(2) test for group comparison, and used a multivariable linear regression analysis to control for covariables. This trial is registered with ClinicalTrials.gov, number NCT01497353. FINDINGS: Between Aug 1, 2011, and Aug 31, 2012, we allocated 274 newborn babies to the introitus group and 272 to the abdomen group. 77 newborn babies in the introitus group and 78 in the abdomen group were ineligible after randomisation (eg, caesarean section, forceps delivery, short umbilical cord or nuchal cord). Mean weight change was 56 g (SD 47, 95% CI 50-63) for 197 babies in the introitus group compared with 53 g (45, 46-59) for 194 babies in the abdomen group, supporting non-inferiority of the two approaches (difference 3 g, 95% CI -5.8 to 12.8; p=0.45). We did not note any serious adverse events during the study. INTERPRETATION: Position of the newborn baby before cord clamping does not seem to affect volume of placental transfusion. Mothers could safely be allowed to hold their baby on their abdomen or chest. This change in practice might increase obstetric compliance with the procedure, enhance maternal-infant bonding, and decrease iron deficiency in infancy. FUNDING: Foundation for Maternal and Child Health (FUNDASAMIN).

ABSTRACT

INTRODUCTION: Although the provision of effective assisted ventilation is the most effective intervention in delivery room resuscitation of depressed newborn infants, there is still limited evidence about which is the optimal device to deliver positive pressure ventilation (PPV). OBJECTIVE: To compare the accuracy of pressures and ventilation rate (VR) delivered to a neonatal simulator with three devices: 240 ml and 450 ml self-infating bags (SIB) and a T-piece resuscitator, and to evaluate the variability in terms of providers' experience. MATERIAL AND METHODS: 76 health care providers divided in two groups according to experience were asked to provide positive pressure ventilation to a neonatal simulator through a facial mask or an endotracheal tube with three ventilating devices: a T-piece resuscitator, a 240 ml and a 450 ml self-infating bags. Participants used each combination of device and interface randomly on 2 consecutive occasions. Mean and maximum PIP and respiratory rate were recorded. Statistical analyses were performed using two-factor analysis of variance for repeated measures. RESULT: SIB 240 and 450 were similar in the mean target peak inspiratory pressure (PIP) but both were significantly different (p < 0.001) from T-piece, although all values were close to the target. Mean VR was over the target for all the devices (p < 0.001). The highest difference found was 7 ± 1.7 breaths/minute with the 240 ml bag when compared with the T-piece using a mask. Experienced operators were closer than novice operators to target VR, regardless of the device or interface. CONCLUSION: The accuracy for the devices was comparable in the variables measured regardless operator´s experience. Overall, the T-piece provided lower PIP while both SIB, higher than the target. The VR was over the target for all the devices. Both SIB and novice participants were associated with higher VR. The intraoperator consistency was comparable in the variables measured with all devices.

ABSTRACT

UNLABELLED: Based on the results of two large RCTs, guidelines from NRP/AAP, ILCOR, ACOG, and from Argentinean scientific societies for intrapartum and postpartum management of pregnancies with Meconium Stained Amniotic Fluid (MSAF) have radically changed. However, there are no data as to current delivery room management of infants born through MSAF. OBJECTIVES: 1) To assess current delivery room approaches in infants born through MSAF in Argentina; 2) To evaluate the adherence to NRP/AAP recommendations among different centers. DESIGN/METHODS: A 20-question anonymous web-mail based survey was sent to 121 institutions with > or = 500 births a year. RESULTS: The response rate was 63% representing 182,540 deliveries/year (26% of the total number of births in the country). Among the surveyed institutions, 24% were located in the city of Buenos Aires and 72% were public hospitals. Although no longer recommended, the following procedures are frequently performed: 1) Oro-nasopharingeal suctioning of meconiumstained infants before the delivery of the shoulders: sometimes, 50% of centers; always, 7 %. 2) Routine tracheal suctioning in vigorous infants, 30%. 3) Glottis exposure under laryngoscopy, 13 % for thin-consistency MSAF and 43% for thick-consistency MSAF. On the contrary, and although strongly recommended, only 69% of depressed infants have tracheal suctioning before ventilation. Up to 7% of centers perform other non recommended procedures such as chest compression and pressure over the larynx, to avoid breathing, and gastric lavage. CONCLUSIONS: In spite of not being currently recommended, intrapartum suction and postnatal intubation and suction of vigorous infants with MSAF are commonly performed in Argentina while in depressed newborns the latter procedure is not always carried out. Our study confirms the frequent gaps observed between scientific evidence, guidelines and clinical practice.

ABSTRACT

Las guías de las sociedades científcas internacionales para asistencia intraparto y posparto de nacimiento con líquido amniótico meconial (LAM) cambiaron radicalmente en los últimos años en base a dos grandes estudios aleatorizados. En la Argentina no hay información acerca de las prácticas que se realizan en estos nacimientos. Objetivos: 1) Conocer qué prácticas se utilizan en la recepción de recién nacidos con antecedente de LAM. 2) Evaluar el grado de adherencia a las recomendaciones actuales. Material y métodos- Encuesta anónima vía internet a centros del país con mayor o igual 500 nacimientos anuales. Se contactaron 121 instituciones. Resultados: Respondieron 76/121 (63 por ciento) correspondientes a 182540 nacimientos anuales (26 por ciento del total de la Argentina). De las respuestas, 24 por ciento fueron de la Ciudad de Buenos Aires y 72 por ciento de hospitales públicos. Se realizan frecuentemente los siguientes procedimientos no recomendados: 1) aspiración orofaríngea y nasofaríngea antes del desprendimiento de los hombros: en el 50 por ciento a veces y en el 7 por ciento siempre; 2) Aspiración endotraqueal de rutina en niños vigorosos, 30 por ciento de los centros; 3) laringoscopia de rutina para visualizar las cuerdas vocales en el 13 por ciento de LAM fluido y 31 por ciento de LAM espeso. Por el contrario, y a pesar de ser una recomendación formal, la aspiración endotraqueal de niños deprimidos antes de comenzar con la ventilación se realiza sólo en el 69 por ciento de los casos. Un 7 por ciento de los centros encuestados, realiza otros procedimientos no recomendados, como comprensión torácica y presión sobre la laringe para evitar que el niño respire y también el lavado gástrico. Conclusiones: La aspiración orofaríngea y nasofaríngea antes del desprendimiento de los hombros y la intubación y aspiración posnatal de niños vigorosos con LAM se realizan frecuentemente en la Argentina.(AU)

ABSTRACT

Meconium aspiration syndrome (MAS) is a life-threatening disorder in newborn infants. Universal intrapartum suction of infants with meconium stained amniotic fluid (MSAF) and postnatal suction of vigorous infants have been used in an attempt to decrease the incidence and severity of the disease by clearing the airway. Both procedures have been proven fruitless when challenged through randomised control trials (RCTs). Endotracheal intubation and suctioning are currently recommended only for non-vigorous infants. Respiratory failure in infants with MAS is frequently treated initially with conventional or synchronized mechanical ventilation. Surfactant administration and high-frequency ventilation (HFV) are commonly used as rescue therapy for severe cases. Nitric oxide (NO) is added when severe pulmonary hypertension is demonstrated. ECMO is an option when other treatments have failed. In the pathophysiology of severe MAS, asphyxia and pulmonary hypertension are considered to be more important than the obstruction of the airways and/or damage to the lung produced by meconium.

ABSTRACT

BACKGROUND: Meconium aspiration syndrome (MAS) is a life-threatening respiratory disorder in infants born through meconium-stained amniotic fluid (MSAF). Although anecdotal data concerning the efficacy of intrapartum oropharyngeal and nasopharyngeal suctioning of MSAF are conflicting, the procedure is widely used. We aimed to assess the effectiveness of intrapartum suctioning for the prevention of MAS. METHODS: We designed a randomised controlled trial in 11 hospitals in Argentina and one in the USA. 2514 patients with MSAF of any consistency, gestational age at least 37 weeks, and cephalic presentation were randomly assigned to suctioning of the oropharynx and nasopharynx (including the hypopharynx) before delivery of the shoulders (n=1263), or no suctioning before delivery (n=1251). Postnatal delivery-room management followed Neonatal Resuscitation Program guidelines. The primary outcome was incidence of MAS. Clinicians diagnosing the syndrome and designating other study outcomes were masked to group assignment. An informed consent waiver was used. Analysis was by intention to treat. FINDINGS: 18 infants in the suction group and 15 in the no suction group did not meet entry criteria after random assignment. 87 in the suction group were not suctioned, and 26 in the no suction group were suctioned. No significant difference between treatment groups was seen in the incidence of MAS (52 [4%] suction vs 47 [4%] no suction; relative risk 0.9, 95% CI 0.6-1.3), need for mechanical ventilation for MAS (24 [2%] vs 18 [1%]; 0.8, 0.4-1.4), mortality (9 [1%] vs 4 [0.3%]; 0.4, 0.1-1.5), or in the duration of ventilation, oxygen treatment, and hospital care. INTERPRETATION: Routine intrapartum oropharyngeal and nasopharyngeal suctioning of term-gestation infants born through MSAF does not prevent MAS. Consideration should be given to revision of present recommendations.
