title: Reduced dose of Rh immunoglobulin following first trimester pregnancy termination.
abstract: The efficacy and safety of a 50-microgram dose of Rh immune globulin for prevention of Rh isosensitization following first trimester vacuum abortion are evaluated in this study. A total of 1027 women undergoing abortion at three outpatient facilities participated in the study; 755 (73.5%) completed follow-up serologic screening 6 months after termination of pregnancy. None showed serologic evidence of Rh sensitization at the time of followup. No serious adverse reactions to the drug were observed.
