title: Heparin for pregnant women with acquired or inherited thrombophilias.
abstract: BACKGROUND
  Thrombophilias, which are associated with a predisposition to thrombotic events, have been implicated in adverse obstetrical outcomes such as intrauterine growth restriction, stillbirth, severe early onset pre-eclampsia, and placental abruption. Heparin administration in pregnancy may reduce the risk of these events.
  
  
  OBJECTIVE
  The objective of this review was to assess the effects of heparin on pregnancy outcomes for women with a thrombophilia.
  
  
  METHODS
  We searched the Cochrane Pregnancy and Childbirth Group trials register (July 2002), MEDLINE, EMBASE, CINAHL, Scidex (via OVID Technologies - July 2002) and reference lists and personal files.
  
  
  METHODS
  Randomized controlled trials comparing heparin with placebo or no treatment, or randomized controlled trials comparing any two treatments. Quasi randomized studies would be included.
  
  
  METHODS
  Data would be abstracted from identified studies and recorded on a paper form by two reviewers.
  
  
  RESULTS
  No studies were included.
  
  
  CONCLUSIONS
  There are no completed trials to determine the effects of heparin on pregnancy outcomes for women with a thrombophilia.
