Abstract
Background: Betamimetic drugs may promote fetal growth by increasing the availability of nutrients and by decreasing vascular resistance. They may also induce adverse effects via their effects on carbohydrate metabolism.
Objectives: The objective of this review was to assess the effects of betamimetic therapy for suspected impaired fetal growth on fetal growth and perinatal outcome.
Search strategy: We searched the Cochrane Pregnancy and Childbirth Group trials register and the Cochrane Controlled Trials Register. Date of the latest search: December 1999.
Selection criteria: Randomised trials of betamimetic therapy compared with no betamimetic therapy or placebo in women with suspected impaired fetal growth.
Data collection and analysis: Eligibility and trial quality was assessed.
Main results: Two studies of 118 women were included. No differences were found between the betamimetic groups and the control groups for low birth weight (relative risk 1.17, 95% confidence interval 0.75 to 1.83), other anthropometric or neonatal morbidity and mortality measures.
Reviewer's conclusions: There is not enough evidence to evaluate the use of betamimetics in promoting fetal growth. Larger studies are needed to investigate possible adverse effects of long-term betamimetic administration.
Conflict of interest statement
None known.
