Complications in early pregnancy or in previous pregnancies can predict the likelihood of further problems in current or subsequent pregnancies ...

Improving care for pregnant women and their babies is of particular importance in countries such as The Netherlands where perinatal mortality is a cause for concern. The Netherlands has a perinatal mortality rate of 9.8 per 1000 (2006 figures) - the second highest rate in Europe [1].

... "There were several interesting findings. To name two: firstly, we found that after any first trimester complication or event, the risk of preterm or very preterm delivery is increased in the subsequent or ongoing pregnancy; secondly, we found that increased risks of adverse obstetric outcome are, in all cases, related to the severity or recurrence, or both, of the first trimester complication or event. To our knowledge, this is the first comprehensive review in which the impact of more than one first trimester complication on adverse obstetric outcome has been investigated systematically."

The researchers found that a history of one or more miscarriages nearly doubled the risk in an ongoing pregnancy of preterm premature rupture of the membrane that surrounds the baby in the womb, and increased the risk of premature or very premature delivery (earlier than 37 or 34 weeks respectively). Recurrent miscarriages (three or more miscarriages) increased the risk in a subsequent pregnancy of all of these conditions; in addition, it increased the risk of placenta praevia (where the placenta partially or completely blocks the cervix) six-fold and congenital malformations nearly two-fold. If a previous pregnancy had to be terminated for any reason, this increased the risk of premature rupture of the membrane, premature and very premature delivery in subsequent pregnancies.

... vaginal bleeding in the first trimester increased the risk of preeclampsia, premature or very premature delivery and more than doubled the risk of low birth weight ...

... "While it is true that most conditions are difficult to prevent, with improved monitoring in high risk pregnancies it is possible to reduce perinatal or postnatal foetal complications.
