Control of Pelvic Blood Flow Using a Novel Pneumatic Abdominal Binder

Background Obstetrical hemorrhage continues to be the leading cause of maternal death; additional means of treatment are needed to reach women who are currently not being saved. We developed the "Ball and Binder", an inexpensive and innovative pneumatic abdominal-pelvic compression device made with a cloth binder and soccer ball. Objective To measure the change in distal aortic blood flow before and after placement of the device. Method A comparative study was done on nine healthy volunteers measuring the flow in the distal aorta before and after placement of a pneumatic abdominal binder. Result Distal aortic flow decreased by over half when the device was inflated. Conclusion An inexpensive pneumatic external abdominal compression "Ball and Binder" device was able to decrease flow to the pelvis by over half. This provides an additional tool for rapid treatment of postpartum hemorrhage unresponsive to routine initial measures.
