Assessing changes in flow velocimetry and clinical outcome following use of an external aortic compression device in women with postpartum hemorrhage

Abstract

Objective To monitor femoral artery blood flow by Doppler velocimetry in women treated for postpartum hemorrhage (PPH) with and without the adjunction of the External Aortic Compression Device (EACD), and to assess the possible adverse effects of the device. Methods Blood flow velocity in the femoral artery, as well as skin color and sensory or motor changes in the lower limbs, were assessed in 120 women with primary PHH of any cause, quasi randomized to either treatment group. Pulse rate, oxygen saturation, respiratory rate, urinary output, and gastrointestinal symptoms were checked in the study group. Results While blood flow velocity was significantly less in the study group than control group ( P < 0.001), the lowest flow volume velocity of 310.40 mL/sec exceeded the acceptable minimum after device application. The intensity of abdominal discomfort correlated with body mass index. No device complications were observed. Conclusion The EACD contributed safely and effectively to the treatment of 60 women with PPH of different causes.
