Re: doctors, respond re: subchorionic hematomasFrom: Marjorie (anonymous@obgyn.net)Tue, 31 Oct 2000 13:04:30 -0600
Dear Rebecca, I am a nursing student at the University of North Dakota. After reading your entery I was inspired to research your question. After searching through many journals I found the research on subchorionic hematomas (SCH) to be conflicting. One research article, Bennett et al.(1996) stated that advanced maternal age, large hematoma, and early gestational age were related to having a spontaneous abortion. Where as Kurjak et al (1995) research showed that where the hematoma was positioned had a greater effect than the size of it. All of the research did show that there was a high rate of spontaneous abortions if the hematoma was present in the first eight weeks of pregnancy. If present after eight weeks, like you are, than premature labor was a higher chance than abortion. In a study by Seki et al (1998), they had a higher rate of chorioamnionitis, infection in the amniotic fluid, in the later of the pregnancy (may be due to premature rupture of membranes). Their research also stated that there was a high rate of the SCH disappearing at the end of the second trimester. In response to your question, the odds of abortion, preterm labor and rupture of membranes are higher in individuals who have persistant subchorionic hematomas. In all of the research I could find, they never discussed any mental or physical problems on the fetus's related to having a subchorionic hematoma during the pregnancy. I hope this has helped answer some of your questions. Attatched are the research articles I have stated in this response. Marjie Mires Schuschke University of North Dakota Student Nurse References 1.
