Loss of
pregnancy before 23 weeks happens in 10 - 20 % of pregnancies. It is associated with chromosomal defects in about
one half to one third of the cases. Many interventions are used, but bed rest is the most common. The objective of this review is to evaluate the effect of prescription of bed rest during
pregnancy to prevent
miscarriage in women at high risk. The paper concludes that although bed rest is widely used to reduce the risk for preterm birth, there is no evidence that this practice is beneficial. Further research evidence is needed to support or refute the efficacy of bed rest in women with high risk for miscarriage.
