Last year, the American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine recommended heparin only for women at elevated risk of VTE, citing a lack of evidence supporting near-universal use.

Rouse and other critics say there have been no solid studies either of how effective heparin is how to improve dj skills preventing clots or of how many women suffer adverse effects from heparin such as hemorrhage or problems in wound healing. Meanwhile, Canadian researchers are planning to test an alternative drug that may be equally effective, safer and cheaper in preventing VTE in women after delivery Ч aspirin.
