AIM: Premature birth is an important cause of maternal morbidity and mortality, associated with high costs for health systems, both public and private. OBJECTIVE: o evaluate the ability of a mobile digital cardiotocograph to perform measurements of clinical variables in a similar way to the conventional cardiotocograph associated with a function test of a remote obstetric monitoring system. METHODS: The pilot study was divided into two stages: (1) non-inferiority study and (2) function test. In the first stage, a pregnant woman was monitored for a period of 20 minutes with a conventional cardiotocograph and, subsequently, with a mobile digital cardiotocograph, for the same period. Variables of fetal heart rate and uterine tonometry were observed. In the second stage, three pregnant women were monitored with the digital mobile cardiotocograph for 20 minutes, with the results transmitted to the mobile devices. RESULTS: Three patients with mean gestacional age of 32.5 ± 8.5 years, weight 75.3 ± 2.6 kg, height of 166 ± 2.24 cm and body max index 27 ± 3.29 kg / m² were evaluated. The fetal heart rate and uterine tonometry measured by the digital mobile cardiotocograph showed no statistically significant difference in relation to the conventional one (p = 0.76 and 0.75 respectively). The fetal heart rate values measured by the devices show a strong statistical correlation (r = 0.98), while those of tonometry have a moderate correlation (r = 0.41). CONCLUSIONS: The mobile digital cardiotocograph showed to have highly correlated means and without statistical differences in relation to the conventional model. The remote transmission and monitoring system is able to provide information necessary for the remote assessment of fetal well-being.
