“…It is therefore possible that the type of response, rather than its mere presence or absence, may prove to be a more refined indicator of fetal status. In accordance with this it has recently been shown that the type and magnitude of intrapartum FHR acceleration responses to sound stimuli differ in vigorous and de pressed newborns [5].…”

The fetal heart rate (FHR) response to a vibroacoustic stimulation was studied in 100 women during active labor. Three types of FHR responses were noted: acceleration, tachycardia of duration longer than 2 min, and combined acceleration-deceleration response. The last type was significantly more common in labors with abnormal FHR tracings. All fetuses demonstrating FHR response to the stimulation, including those with abnormal FHR tracings, had good outcome. The vibroacoustic stimulation is easily performed, noninvasive, and has no contraindications. Its possible application as an intrapartum test of fetal well-being awaits further clinical confirmation.

“…Several research groups have already demonstrated the link between fetal evoked responses to auditory stimuli and conditions during labor (Eswaran et al, 1999;Luz, 1985;Luz, Lima, Luz, & Feldens, 1980). In a large group of subjects, increase in fetal MCA flow was associated with gestational hypertension when compared to normotension (Plesinac et al, 2013).…”

This study investigated the correlation between maternal anxiety and blood flow changes through the fetal middle cerebral artery (MCA) after defined acoustic stimulation in 43 normotensive (C) and 40 gestational hypertensive (GH) subjects.Neonatal outcomes (gestational age at birth, Apgar score, birth weight) in the C and GH groups were analyzed. State (STAI-S) and trait (STAI-T) anxiety was assessed using Spielberger's questionnaire. The MCA blood flow was assessed once between 28 and 41 weeks of gestation using color Doppler ultrasound before and after application of defined acoustic stimulus. Relative size of the Pulsatility index (Pi) change (RePi) was calculated. The general hypotheses were: (1) women in GH group would have higher anxiety; (2) higher anxiety correlates with higher RePi change and poorer neonatal outcome; (3) fetuses from the GH group would have poorer neonatal outcome.Subjects from the GH group had higher STAI-T and RePi compared to the C group. A positive correlation between RePi and STAI-S, STAI-T, and systolic/diastolic blood pressure was found in both groups. There were more preterm deliveries in the GH group compared to the C group. A significant effect of STAI-T on body weight was observed in the C and GH group. There was a predictive effect of STAI-T and RePi on the C group, and STAI-S, STAI-T, diastolic blood pressure, and RePi on the GH group in terms of neonatal body weight. This study demonstrates an association between antenatal anxiety in GH women and increased fetal cerebral circulation in response to defined auditory stimulation.
