The first case of novel coronavirus disease of 2019 caused by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) was reported in November2019. The rapid progression to a global pandemic of COVID-19 has had profound medical, social, and economic consequences. Pregnant women and newborns represent a vulnerable population. However, the precise impact of this novel virus on the fetus and neonate remains uncertain. Appropriate protection of health care workers and newly born infants during and after delivery by a COVID-19 mother is essential. There is some disagreement among expert organizations on an optimal approach based on resource availability, surge volume, and potential risk of transmission. The manuscript outlines the precautions and steps to be taken before, during, and after resuscitation of a newborn born to a COVID-19 mother, including three optional variations of current standards involving shared-decision making with parents for perinatal management, resuscitation of the newborn, disposition, nutrition, and postdischarge care. The availability of resources may also drive the application of these guidelines. More evidence and research are needed to assess the risk of vertical and horizontal transmission of SARS-CoV-2 and its impact on fetal and neonatal outcomes.
Key Points• The risk of vertical transmission is unclear; transmission from family members/providers to neonates is possible.• Optimal personal-protective-equipment (airborne vs. droplet/contact precautions) for providers is crucial to prevent transmission. • Parents should be engaged in shared decision-making with options for rooming in, skin-to-skin contact, and breastfeeding.
, for the SLI Trial Investigators abstract BACKGROUND: Studies suggest that giving newly born preterm infants sustained lung inflation (SLI) may decrease their need for mechanical ventilation (MV) and improve their respiratory outcomes.
Aims: To measure and compare cardiac troponin I, cardiac troponin T and creatine kinase MB concentrations in the umbilical cord blood of healthy term infants and to investigate the relationship between maternal and neonatal troponin values at birth. Methods: Troponin I, troponin T and creatine kinase MB concentrations were measured from the umbilical cord samples of 85 healthy term neonates and in the blood samples of their respective mothers at birth. Results: Median (interquartile range) umbilical cord concentrations were 0 μg/L (0–0) for troponin I, 0 μg/L (0–0.019) for troponin T and 4.90 μg/L (3.90–6.61) for creatine kinase MB. Troponin I and T concentrations were higher than the detection limit for the assay in 2 (2.3%) and 41 (48.2%) neonates, respectively. Two mothers (2.3%) had cTnT levels above the detection limit; none of them had increased levels of cTnI.
Conclusion: Probably owing to differences in expression and assay detection limits, cord blood troponin T concentrations are frequently over the detection limit at birth, while troponin I is mostly undetectable and comparable with that in healthy pregnant women. These cardiac regulatory proteins are of neonatal origin and are not influenced by maternal levels.
BackgroundWe assessed the effect of an adapted neonatal resuscitation program (NRP) course on healthcare providers’ performances in a low-resource setting through the use of video recording.MethodsA video recorder, mounted to the radiant warmers in the delivery rooms at Beira Central Hospital, Mozambique, was used to record all resuscitations. One-hundred resuscitations (50 before and 50 after participation in an adapted NRP course) were collected and assessed based on a previously published score.ResultsAll 100 neonates received initial steps; from these, 77 and 32 needed bag-mask ventilation (BMV) and chest compressions (CC), respectively. There was a significant improvement in resuscitation scores in all levels of resuscitation from before to after the course: for “initial steps”, the score increased from 33% (IQR 28–39) to 44% (IQR 39–56), p<0.0001; for BMV, from 20% (20–40) to 40% (40–60), p = 0.001; and for CC, from 0% (0–10) to 20% (0–50), p = 0.01. Times of resuscitative interventions after the course were improved in comparison to those obtained before the course, but remained non-compliant with the recommended algorithm.ConclusionsAlthough resuscitations remained below the recommended standards in terms of quality and time of execution, clinical practice of healthcare providers improved after participation in an adapted NRP course. Video recording was well-accepted by the staff, useful for objective assessment of performance during resuscitation, and can be used as an educational tool in a low-resource setting.
To determine the effect of a short course of methylxanthines on renal function and on urinary calcium excretion, 20 premature neonates affected by apnea or moderate respiratory distress syndrome were randomly assigned to either a theophylline treatment or to a caffeine treatment group. The protocol included a 24-hour pretreatment study period (I) and a subsequent 24-hour period (II) following 5 days of theophylline (loading dose 5 mg/kg i.v., maintenance dose 2.5 mg/kg/l2 h) or caffeine (loading dose 10 mg/kg i.v., maintenance dose 2.5 mg/kg/l2 h) administration. Pre- and postxanthine treatment serum sodium, potassium, calcium and phosphorus remained stable, while serum creatinine decreased significantly (p < 0.05). Furthermore, from period I to period II, sodium urine excretion, fractional Na excretion and creatinine clearance remained statistically comparable in both study groups, along with a significant increase (p < 0.05) in calciuria, urinary Ca/creatinine and urinary Ca/Na. Predose caffeine and theophylline serum levels, assessed on the 5th day of treatment, were 12.8 ± 1.8 and 7.9 ± 1.7 μg/ml, respectively. Compared to control healthy untreated prematures, the studied premature infants showed a statistically significant increase in urine calcium excretion (10- to 15-fold), which was more evident in the theophylline group. Our data suggest further investigation to determine the long-term renal effects of methylxanthines in premature neonates, to improve assessment of the risk of nephrocalcinosis and osteopenia, in particular in association with various diuretic therapies.
Neonatal transfers and inborn neonates with pneumothorax have different clinical characteristics and outcome. This information could be useful for all persons involved in the interhospital care of perinatal patients.
Infants born by elective caesarean delivery at term are at increased risk for developing respiratory disorders compared with those born by vaginal delivery. A significant reduction in neonatal RDS would be obtained if elective caesarean delivery were performed after 39 + 0 gestational weeks of pregnancy.
