Objective: To analyse the correlation between Doppler fetal heart indicators such as mitral ratio (E/A), acceleration time/ejection time (AT/ET) ratio in the main of pulmonary artery to the lecithin/sphingomyelin ratio (L/S) dosed in the amniotic fluid.
Material and Methods: Prospective study including singletons between 24 and 39 weeks of gestation, for whom caesarean delivery was planned. E/A and AT/ET ratios were realised during the 24 hours before birth. The L/S ratio was assayed by thin-layer chromatography, from samples of amniotic fluid.
Results: Thirty fetus were included, for a median (IQR) gestational age of 37 weeks (33.8-38.7) and a median weight birth of 2600 g (1888-3140). The correlation between the E/A and L/S ratios was positive: r = 0.56 (95% CI [0.24–0.76], p<0.01) while the correlation .. View More»
