AbstractThe 1:2 matched case-control retrospective study of postpartum hemorrhage (PPH) was undertaken in Suizhou, Hubei Province from 1 January 1990 to 31 December 1991. The subjects consisted of 109 women who had a PPH (blood loss equal to or more than 500 ml) and 218 women whose blood loss at delivery was less than 200 ml. The results showed that multiparity, age younger than 20 or older than 36, long second and third stages of labour, abortion, low income, lack of obstetric care, etc, were identified as risk factors statistically.
