ICR Obstetrical Issues Flashcards
Amniocentesis
Aspiration of amniotic fluid, usually transabdominally, for diagnostic or therapeutic purposes
Amniotic Fluid
Fluid confined by the amnion. Amnion is the thin, tough membranous sac that encloses the embryo or fetus of a mammal.
Ante partum
Before labor or delivery
Blood flow, uteroplacental
Circulation by which the fetus exchanges nutrients and waste products with the mother
Chloasma
mask of pregnancy. Irregular brownish patches of various sizes that may appear on the face during pregnancy or during the use of oral contraceptives, secondary to elevated levels of estrogen and progesterone
Chorionic villus sampling
Transcervical or transabdominal sampling of the chorionic villi for cytogenetic evaluation of the fetus (often used to diagnose aneuploidies)
Cordocentesis (Percutaneous umbilical blood sampling, PUBS)
Fetal assessment and therapeutic technique in which a needle is passed into the umbilical vessel and blood is sampled or treatment is given.
Corpus luteum
The cystic structure formed in the ovary at the site of a ruptured ovarian follicle. This produces progesterone which supports the pregnancy until the placenta has developed and taken over this role.
Culdocentesis
Needle aspiration of intraperitoneal fluid or blood through a puncture of the posterior vaginal fornix into the cul-de-sac.
Curettage
Scraping of the interior of a cavity or other surface with a curette. Fractional or Suction
Decidua
Identifiable changes in the endometrium and other tissues in response to the hormonal effects of progesterone.
D immunoglobulin
Immunoprotein that prevents D sensitization. Commericially known as Rhogam. Attaches to antibodies made when an Rh negative person has been exposed to Rh positive blood
Ecclampsia
Convulsive form of preeclampsia ecclampsia syndrome. Tonic-clonic seizures
Ectopic Pregnancy
Pregnancy located outside of the uterine cavity
Ectropion
growth of columnar epithelium of the endocervix onto the ectocervix
Embryo
Conceptus from the blastocyst stage to the end of the 8th week.
Fetal Testing (non-stress testing)
Evaluation of the fetus by electronic fetal heart rate monitoring, when not in labor.
Fetus
Conceptus from 8 weeks until birth
Gonadotropin, Human chorionic (HCG)
Glycoprotein hormone produced by the syncytiotrophoblast and is immunologically similar to LH
Gravida
Pregnant Woman
Gravidity
Pregnant state, or total number of pregnancies a woman has had, including the current pregnancy
Hydatidiform mole
Pathologic condition of pregnancy characterized by the hydropic degeneration of the chorionic villi and variable degrees of trophoblastic proliferation.
Intervillous space
Space in the placenta in which maternal blood bathes chorionic villi, allowing the exchange of materials between the fetal and maternal circulations
Intrauterine fetal demis (IUFD, stillbirth)
Intrauterine death of the fetus. Fetal death prior to 500 grams is usually classified as an abortus.
