Obstetrics Vocabulary
Abortion
Termination of a pregnancy before the fetus is viable.
Alpha-fetoprotein test (AFP)
A maternal blood test to detect potential fetal abnormalities such as neural tube defects or multiple pregnancies; The AFP is taken between 14 and 19 weeks gestation.
Amenorrhea
Absences of the flow of menses, no period; one of the first signs of pregnancy or menopause.
Amniocentesis
Surgical puncture to remove a small amount of amniotic fluid through a needle via the abdomen. The fluid is tested for any potential fetal abnormalities.
Artificial insemination
A process where the semen is introduced into the vagina by mechanical means, thus called artificial.
Breech
The position of the fetus is feet first. Ideally, the position of the fetus should be headfirst for a safer delivery.
Caesarian section (CS, c-section)
Delivery of the fetus through an abdominal incision.
Cephalopelvic disproportion
A condition where the infant’s head is larger than the pelvic outlet and therefore will require a c-section.
Cerclage
A suture inserted into the cervix to prevent dilation and prevention miscarriage. The suture is removed when the fetus is full-term and allows the vaginal delivery to proceed.
Cephalic version
Pertaining to turning the head; this procedure is done on the fetus when they are in the head-down position.
Chorionic villus sampling
A small piece of placenta is taken and tested to determine potential for birth defects.
Dilation and curettage (D&C)
A procedure where the cervix is dilated (widened) and a curette (a sharp instrument) is used to remove the lining of the uterus. This procedure is conducted when there is abnormal bleeding from the uterus and also to remove any products of conception, for example following an incomplete miscarriage or abortion.
Eclampsia
A very serious condition in pregnancy with hypertension; patients are at high risk of coma, convulsions, and even death.
Ectopic pregnancy
The embryo implants any other place but the inner endo-uterine lining.
Episiotomy
A procedure where an incision is made to widen the vaginal opening to prevent ripping or tearing of the perineum during delivery.
Gestation
The process of being pregnant.
Gestational Diabetes
The condition or developing diabetes during pregnancy. The newborn tend to be large at delivery and the mother is monitored closely for weight gain and glucose testing. The goal is to balance the sugars so the fetus is not too large for a vaginal delivery.
Gestational Hypertension
A condition where there is an increase in blood pressure during pregnancy. Blood pressure is monitoring closely during pregnancy for the safety of the mother and infant.
Hyperemesis
Excessive vomiting during pregnancy.
Hyperemesis Gravidarum
Hyperemesis can occur with any pregnant women, even a woman who miscarries. Often these women may require hospitalization for fluid and electrolyte intake.
Induction
The process of bringing on or starting labour. This may be done with a membrane sweep or through the use of IV oxytocin.
In vitro Fertilization (IVF)
A process where the ova is fertilized outside the body and then implanted into the uterus.
Meconium Staining
When the fetus defecates while in utero; the first defecation is called meconium, it is black and sticky. If the infant inhales the meconium upon delivery or through the birth canal, the meconium can be aspirated into the lungs and stick to the lung tissue. The newborn will have problems breathing and go into distress. The newborn’s umbilical cord will be stained a brownish colour.
Natal
Pertaining to born.
Neonatal
Pertaining to the newborn. For example neonatal record, neonatal unit
Non-stress test
Test conducted on the pregnant woman to assess the fetal heart rate (FHR).
Nulligravida
A woman who has never been pregnant.
Obstetrician
The person who specializes in the study of obstetrics and gynecology and are referred to as OB/GYN Obstetrics and Gynecology.
Oligohydramnios
A condition where there is minimal amniotic fluid within the placental sac. Too little fluid can restrict the fetus from movement and growth.
Oocyte
Female gamete.
Oxytocia
A rapid birth.
Placenta Abruptio or Abruptio Placenta
Occurs when the placenta prematurely becomes detached from the uterine wall. This is a medical emergency and requires an immediate c-section to safe both the woman and infants lives. the infant will not be getting oxygen from the mother and the mother may hemorrhage.
Placenta Previa
Occurs when the placenta partially or completely covers the cervical os (opening).
Polyhydramnios
A condition where there is excessive amniotic fluid in the placenta. The delivery will be a c-section to prevent bleeding during delivery of the fetus.
Preeclampsia
The abnormal condition in pregnancy where the patient experiences hypertension, edema and proteinuria.
Primigravida
First pregnancy.
Sperm
Male gamete (spermatozoon).
Vaginal Birth Following a C-Section
Having a vaginal delivery after a previous c-section delivery.
Zygote
Process of fertilization is complete and results in a single-celled diploid zygote with all the genetic instructions it needs to develop into a human.
Zygote Intrafallopian Transfer (ZIFT)
Mixing of the ova and sperm in a laboratory. Fertilization is confirmed to grow into zygotes and then are inserted into the Fallopian tubes (Healthwise Staff, 2018).
