There are two great fears for those who attend childbirth; these have not changed over centuries. The first is massive postpartum hemorrhage and the other is a shoulder dystocia. Postpartum hemorrhage is a significant cause of maternal morbidity and mortality worldwide among both developed and developing countries. This problem daily faces the 35,000 obstetrician/gynecologists and 17,000 family physicians who deliver about a million babies yearly in this country.
