Hemodynamic changes in women with symptoms of supine hypotensive syndrome

ConclusionsMaternal hemodynamic adaptations were found to be consistent across groups irrespective of whether the women had symptoms of supine hypotension. In both groups a reduction in blood flow through the inferior vena cava occurred in the supine position with a subsequent reduction in cardiac output. Both groups showed a compensatory increase in blood flow through the azygos vein in order to partially compensate for this. Taking into account the effect of maternal position, women with symptoms were found to have reduced azygos flow compared to asymptomatic women. There was a significant increase in heart rate when the women were supine compared to the left lateral position.
