EFFECTS OF ACOUSTIC STIMULATION ON BIOPHYSICAL PROFILE TESTING TIME

Biophysical profile (bpp) test is the most commonly used antenatal test of fetal well-being. purpose of this study is determining the influence of acoustic stimulation (as) on bpp testing time. about 55 pregnant women at 35 to 42 weeks who referred to department of obstetric & gynecology at university of medical sciences, tabriz, iran, were selected randomly. we used abdominal ultrasound guidance to place buzzer like device with power of 110 db at the skin surface of the maternal abdomen, close to the fetal head. bpp test performed and bpp mean testing time calculated before and after as. data compared and analyzed by paired t-test. the results showed that fetal as reduces the overall mean testing time from 24 minutes to 5 minutes. this clinical application can be helpful in busy clinics when rapid assessment of fetal health is required.
