A randomized controlled trial of a new fetal acoustic stimulation test for fetal well-being.
Annual Meeting of the Pacific Coast Obstetrical and Gynecological Society. Sunriver, Oregon (USA), 1996/10/02.
Our purpose was to determine (1) whether a fetal acoustic stimulation test results in more palpable fetal movement compared with a mock test (control) and (2) whether palpated fetal movements after a fetal acoustic stimulation test are accompanied by a reactive nonstress test.
In a randomized controlled trial we studied women seen in the labor and delivery suite for various indications.
Women were excluded for multiple gestation,<31 weeks'gestational age, treatment with magnesium sulfate or narcotics, or ruptured membranes.
Informed consent was obtained from eligible women, who were then randomized to a test or control group.
We placed an acoustic stimulator on the abdomen of each woman, but only the test group was stimulated.
We assessed fetal movement by a grading system : 0=no fetal movement felt by patient or tester, 1=fetal movement felt by patient only, 2=fetal movement felt by tester, 3=visual movement seen by tester.
A positive fetal acoustic stimulation test result was defined as one with any fetal movement felt or seen by the tester (grades 2 or 3).
We then performed a nonstress test.
We compared rates of a positive fetal acoustic stimulation test in the test and control groups with the X2 test.
A p value<0.05 was considered significant.
We randomized 297 women to the test group and 280 women to the control (mock test) group. (...)
