[Changes of blood dynamics measured by vein impedance blood stream charts in pregnant women].
The vein impedance blood stream charts were analysed in 32 pregnant women with gestational age between 38-42 weeks and in 31 healthy nonpregnant women as well. Measurement included maximal venous out flow (MVO), 3-sec venous outflow (VO), venous capacity (VC) and arterial blood flow (ABF). The results showed that all the parameters mentioned above were significantly lower in pregnant women either in 3rd trimester or at post partum when compared with nonpregnant women (P < 0.01). All parameters were increased after delivery. The significant change was only seen in VC. It suggested that the vein impedance blood stream chart might be used as an early diagnostic tool for thrombophlebitis occurred in lower extremities after delivery.
