Study of the Sensitivity of Manual vs Electric Aspiration to Detect Completed Early Abortion

2014-07-23 21:09:51 | BioPortfolio


With sensitive urine pregnancy tests, women are now able to confirm very early pregnancies. However, approximately one third of abortion facilities do not offer abortions at less than six weeks of pregnancy. Providers may be concerned that they will be unable to identify products of conception (POCs) in uterine aspirates after early abortion and about the time, cost and risk associated with following serum hCG levels when completed abortion cannot be confirmed by gross inspection. Many providers believe that manual vacuum aspiration (MVA) causes less destruction of pregnancy tissue and therefore may increase the likelihood of identifying POCs on gross inspection. No published reports specifically compare MVA to electric vacuum aspiration (EVA) for the detection of complete products of conception and none compare MVA and EVA at less than 6 weeks of pregnancy. We, the investigators, propose to conduct a randomized controlled trial comparing the sensitivity of MVA to EVA for the detection of completed abortion in 492 women with pregnancies of less than 6 weeks gestation at a large inner city family planning center. We will measure positive identification of POCs on gross inspection in patients subsequently shown to have completed abortions. We hypothesize that the rate of true positive detection of POCs will be higher in dilation and curettage (D&C) using MVA than EVA.
