“…Similar to our study, Guan et al, by study on 284 healthy singleton fetuses, inferred that there is positive correlation between GA and AT, AT/ET and PSV (25). This is an expected finding because PVR normally decreases with increasing GA and AT (i.e.…”

Background: Doppler-derived fetal pulmonary artery acceleration time (PAAT) and acceleration-to-ejection time ratio (AT/ET) are important as predictors of a variety neonatal pulmonary diseases. The evaluation of PAAT and PA AT/ET are meaningful when simultaneous right and left heart studies are done. The unique cardiovascular physiology in the fetus, as the only period of life with physiologic systemic pulmonary hypertension, overemphasizes the significance of simultaneous study. However, studies on comparative fetal velocitometry of PA and aorta are scarce. Objectives: The aims of this study were to provide reference values for peak systolic velocity (PSV), pulsatility index (PI), acceleration time (AT), ejection time (ET) and AT/ET ratio of PA and aorta in the singleton pregnancies with healthy fetuses. We compared these Doppler parameters of PA and aorta. Methods: A cross-sectional study was performed on 146 fetuses. We measured PSV, PI, AT, ET and AT/ET in the PA and aorta and compared the values. We evaluated the correlation between these parameters and the fetal gestational age (GA). Results: Mean ± SD of gestational age of fetuses were 21 ± 4 weeks. PSV, AT and AT/ET of PA and aorta increased with gestational age.

“…It is primarily a disease of premature neonates, with an incidence and severity that are highly dependent on gestational age (GA) . As RDS is an important cause of neonatal morbidity and mortality, a number of biochemical tests have been developed to predict the risk of RDS . Some of these tests, including amniocentesis, are invasive and are associated with risks to the pregnancy.…”

“…Corticosteroids administered antenatally may increase production of surfactant in the fetal lungs, and an increase in the fetal pulmonary blood flow may be another possible explanation for such reduced morbidity. [3][4][5][6][7] Also, Doppler velocimetry of the umbilical artery (UA) was found to be affected by corticosteroid administration. 8 On the other hand, repeated doses of steroids may especially have adverse effects on fetal growth or neuronal myelination.…”

Tiempo de aceleración y tiempo de eyección de la arteria pulmonar fetal como predictor de madurez pulmonar Resumen El propósito principal de la medicina materno-embrio-fetal es lograr reducir la morbilidad y mortalidad durante la gestación. Al hablar de valoración de madurez pulmonar nos enfrentamos a un reto diagnóstico que nos permitirá, etiquetar a un feto como pulmonarmente maduro a pesar de no cumplir las 37 semanas de gestación, lo cual optimizará tanto el manejo intrauterino y posterior al nacimiento, en vista de que al hablar de madurez pulmonar se asocia a disminución de problemas en la adaptación del recién nacido al medio extrauterino sin la necesidad de cuidados especiales. El presente artículo permitió analizar y evidenciar el uso del tiempo de aceleración y de eyección de la arteria pulmonar fetal como predictor de madurez pulmonar neonatal. Se concluye ante la ausencia de una prueba estándar de oro segura que determine la madurez pulmonar fetal y que a su vez sea no invasiva, surge el interés en investigar los valores y los cambios según la edad gestacional de la relación entre TA, TD, TE en el tronco de la arteria pulmonar, constituyéndose en una técnica confiable que permite mejorar los resultados perinatales y disminuye el número de ingresos a la terapia neonatal.Palabras claves: Tiempo de aceleración/Tiempo de eyección sistólico (TA/TE), madurez pulmonar, arteria pulmonar fetal. AbstractThe main purpose of maternal-embryo-fetal medicine is to reduce morbidity and mortality during pregnancy. When talking about the assessment of lung maturity, we face a diagnostic challenge that will allow us to label a fetus as lung-ripe despite not reaching 37 weeks of gestation, which will optimize both intrauterine and post-natal management, in view of that when talking about lung maturity is associated with a decrease in problems in the adaptation of the newborn to the extrauterine environment without the need for special care. The present article allowed us to analyze and demonstrate the use of acceleration and ejection time of the fetal pulmonary artery as a predictor of neonatal pulmonary maturity. It is concluded in the absence of a safe gold standard test that determines the fetal lung maturity and that in turn is non-invasive, the interest arises in investigating the values and changes according to the gestational age of the relationship between TA, TD, TE in the trunk of 44 Tiempo de aceleración y tiempo de eyección de la arteria pulmonar fetal como predictor de madurez pulmonar the pulmonary artery, becoming a reliable technique that improves perinatal outcomes and decreases the number of admissions to neonatal therapy.

The role of doppler waveforms in the fetal main pulmonary artery in the prediction of neonatal respiratory distress syndrome

Abstract: Fetal MPA Doppler velocimetry can reliably be obtained throughout gestation. AT and AT/ET ratios of the fetal MPA Doppler waveform may help identifying fetuses at risk of developing neonatal RDS.
