Objective: To determine differences between the responses in the fetal heart rate and fetal movements employing vibroacoustic stimulation using standardized electronic monitoring, and simplified vibroacoustic stimulation ultrasound in the Service Perinatology Hospital “Dr. Adolfo Lara Prince “of Puerto Cabello, Estado Carabobo. Methods: Descriptive study, cross-field, non-experimental, comparison of two diagnostic procedures. The populations were patients who attended in the period June 2013 - June 2014. There were 158 patients studied, 97 vibroacoustic stimulation was used standardized with electronic monitoring, and 61 simplified vibroacoustic stimulation with ultrasound. Results: Mean maternal age was 25.75 years ± 0.53, variability 6.62 years, predominantly between 20-29 (58.86 %). Average gestation week 35 wk ± 0.18, with dispersion 2.32, among 35-38 weeks = 86 54.43.% cases. A 67.72 % had pathologies (107 cases), the prevailing pregnancy-induced hypertension (16.46 % = 26 cases), then oligohydramnios (9.49 % = 15 cases). Fetal reactivity was reported at 81.97 % with simplified vibroacoustic stimulation (50 cases), with vibroacoustic stimulation 97.94 % (95 cases); both figures are high, statistically significant difference. The average time in the procedures vibroacoustic stimulation 20.8 min, 9-35 min range; with simplified vibroacoustic stimulation the average was 9.4 min, ranging 5-12 min; there were statistically significant differences. Conclusion: Both tests showed high fetal reactivity; the average time to complete the simplified vibroacoustic stimulation was lower. This one is simpler, lower cost, more patients studied in time unit; extensive research is recommended before a final implementation.
