BACKGROUND Stillbirth remains a problem; therefore requires delving analyzed to assess their causes and strategies that prevent or decrease. OBJECTIVE To establish the frequency, describe the sociodemographic and medical characteristics, and factors associated with fetal death in a high complexity hospital in Bogotá, Colombia. MATERIALS AND METHODS A cross-sectional study quantifying stillb...

It has previously been reported that active glottic adduction is present during prolonged apneas but absent during periods of breathing movements in fetal lambs in utero. The present study was aimed at examining the precise coordination between fetal breathing movements [diaphragm electromyographic (EMG) activity (Di EMG)] and glottic adduction [thyroarytenoid muscle EMG activity (TA EMG)]. Ele...

We have tested a new Doppler ultrasound apparatus which registers both fetal movements and fetal heart rate with a single transducer. To evaluate the reliability of the recognition of movements we also observed them simultaneously by real time ultrasound. In 20 patients with normal pregnancies between the 30th and 42nd week of gestation, taking the real time ultrasound as reference the positive...
