ABSTRACTObjetive: Describe the maternal hemodynamic patterns in pregnant women with a history of preeclampsia.
Material and Method: Transversal descriptive study, which included 77 patients who underwent non-invasive hemodynamic monitoring with USCOM® obtained by Doppler: cardiac output, cardiac index, index of vascular resistance and systemic vascular resistance. With the data we built tables ranking of the variables studied, we made descriptive statistical correlations between variables, and confidence intervals for the mean were built with 95 % confidence.
Results: The hemodynamic pattern corresponded to a pregnancy at 20 weeks with cardiac output of 4.8 L/min, heart rate 2.8 L/min/m2 of body surface, 1462 dyne vascular resistance and mean arterial pressure of 80 mmHg. Increased mean arterial blood pressure is associated with the fall in cardiac output and increased vascular resistance which can be easily monitored by Doppler ultrasonography USCOM®.
Conclusion: Hemodynamic changes previously described in term pregnancies are reproducible and attributable to earlier gestation even with history of preeclampsia, this can help predict patients at risk for developing severe preeclampsia, USCOM® through an easy and convenient way for patient by monitoring changes in their hemodynamic patterns.
