Maternal deaths in South Australia 1970 to 1975.
During the period from 1970 to 1975 there were 128 087 confinements in South Australia and 30 maternal deaths were reported, representing a maternal mortality rate of 23 per 100 000 confinements which is lower than in previous reports. Twenty-one deaths were directly due to complications of pregnancy and childbirth, and  nine were due to associated conditions. The fall in the maternal mortality rate was largely due to a reduction in the number of deaths from abortion and in the number of confinements to women in the higher-risk older age groups. Infection appeared for the first time as a major cause of maternal death. Avoidable factors may have contributed to 47% of the deaths.
