Abortion Flashcards
- What is the definition of abortion?
- At what stage of pregnancy does abortion typically occur?
- What are the two main categories of abortion?
- What are the potential complications of abortion?
Abortion refers to the expulsion of the foetus and other products of conception before the 28th week of pregnancy.
It may occur
— spontaneously (threatened, inevitable, incomplete, complete or missed)
or
— induced (therapeutic, criminal).
Both spontaneous and induced abortion may become complicated by infection
— (sepsis) and/
— profuse bleeding
Spontaneous Abortion*

- What is threatened abortion?
- What is inevitable abortion?
- What is incomplete abortion?
- What is missed abortion?
Types of spontaneous Abortion
—threatened
— inevitable,
— incomplete
— complete
— missed
Here are the definitions:
1. Threatened Abortion:
A threatened abortion is a condition where vaginal bleeding occurs during the first 20 weeks of pregnancy, but the cervix remains closed and the fetus is still viable. Symptoms include:
- Scanty to moderate painless vaginal bleeding
- Mild pelvic discomfort
- Uterine size compatible with gestational age
- No cervical effacement or dilatation
2. Inevitable Abortion:
An inevitable abortion is a condition where vaginal bleeding and cervical dilatation occur, indicating that the abortion process has begun and cannot be stopped.
Symptoms include:
- Lower abdominal pain
- Heavy vaginal bleeding
- No fetus or products of conception passed per vagina
- Painless loss of liquor per vagina
3. Incomplete Abortion:
An incomplete abortion occurs when parts of the products of conception are expelled, but others remain inside the uterus.
Symptoms include:
- Heavy vaginal bleeding
- Severe abdominal pain
- Fever
- Cervical dilatation with partial expulsion of products of conception
4. Missed Abortion:
A missed abortion, also known as a missed miscarriage, occurs when the fetus dies but remains inside the uterus.
Symptoms include:
- Absence of fetal movements
- Decreased pregnancy symptoms
- Vaginal bleeding or spotting
- Cervix closed, with no expulsion of products of conception
5. Complete Abortion:
A complete abortion occurs when all products of conception are expelled from the uterus.
Symptoms include:
- Cessation of vaginal bleeding
- Cervical closure
- Uterine size returns to normal
- Complete expulsion of products of conception

- How do fetal abnormalities contribute to spontaneous abortion?
- What is the role of an incompetent cervix in spontaneous abortion?
- How do chronic illnesses increase the risk of spontaneous abortion?
- What is the impact of trauma on spontaneous abortion?
Causes
1. Spontaneous Abortions:Infections e.g.
— malaria,
— UTI,
— bacterial vaginosis etc.
Other causes:
y Foetal abnormalities
y Incompetent cervix
y Chronic illness e.g. diabetes, thyroid disorders, sickle cell dis-
ease etc.
y Trauma
- How do fetal abnormalities contribute to spontaneous abortion?*
Fetal abnormalities, also known as congenital anomalies, can contribute to spontaneous abortion in several ways:
- Chromosomal abnormalities (e.g., Down syndrome, Turner syndrome)
- Structural anomalies (e.g., heart defects, neural tube defects)
- Genetic mutations
- Incompatible with life conditions (e.g., severe birth defects)
These abnormalities can disrupt normal fetal development, leading to:
- Miscarriage
- Fetal death
- Premature separation of the placenta
- What is the role of an incompetent cervix in spontaneous abortion?*
An incompetent cervix, also known as cervical insufficiency, is a condition where the cervix dilates prematurely, leading to spontaneous abortion. This can occur due to:
- Weakened cervical tissue
- Previous cervical trauma or surgery
- Congenital cervical abnormalities
- Hormonal imbalances
An incompetent cervix can cause:
- Preterm cervical dilation
- Premature rupture of membranes
- Fetal expulsion
4. How do chronic illnesses increase the risk of spontaneous abortion?
Chronic illnesses can increase the risk of spontaneous abortion by:
- Affecting the mother’s overall health
- Disrupting hormonal balances
- Causing inflammation and oxidative stress
- Increasing blood pressure and cardiovascular stress
Examples of chronic illnesses that may increase the risk of spontaneous abortion include:
- Diabetes
- Thyroid disorders
- Sickle cell disease
- Hypertension
- Autoimmune disorders (e.g., lupus)
5. What is the impact of trauma on spontaneous abortion?
Trauma, physical or emotional, can increase the risk of spontaneous abortion by:
- Causing direct injury to the uterus or cervix
- Triggering stress responses, releasing hormones that may disrupt pregnancy
- Increasing blood pressure and cardiovascular stress
- Disrupting placental function
Types of trauma that may contribute to spontaneous abortion include:
- Physical abuse
- Accidents (e.g., car accidents, falls)
- Emotional stress (e.g., anxiety, depression)
- Surgical trauma (e.g., previous uterine surgery)
- What are the symptoms of threatened abortion?
- What are the signs of threatened abortion?
- What investigations are necessary for threatened abortion?

Signs
y The cervix is dilated with the membranes bulging
y There may be loss of liquor

rising pulse with reducing volume, falling BP and cold clammy skin
Investigations
y FBC and sickling

- What is therapeutic abortion?
- What is criminal abortion?
- What are the risks associated with unsafe abortions?
- How do medications interfere with pregnancy in induced abortion?
- What are the potential complications of induced abortion?
Here are the answers:
- What is therapeutic abortion?
Therapeutic abortion, also known as medical abortion, is a type of induced abortion performed for medical reasons, including:
- Fetal anomalies or abnormalities
- Pregnancy-related health risks
- Life-threatening conditions (e.g., ectopic pregnancy)
- Severe psychological or social indications
Therapeutic abortion aims to protect the woman’s physical and mental health.
- What is criminal abortion?
Criminal abortion refers to an illegally performed abortion, often by an unqualified practitioner or under unsafe conditions. This can include:
- Backstreet or clandestine abortions
- Self-induced abortions using harmful methods
- Abortions performed without medical supervision
Criminal abortion poses significant health risks due to unsterile conditions and lack of proper care.
- What are the risks associated with unsafe abortions?
Unsafe abortions carry numerous risks, including:
- Infection and sepsis
- Hemorrhage and blood loss
- Uterine perforation
- Cervical damage
- Infertility and reproductive complications
- Psychological trauma
- Death
- How do medications interfere with pregnancy in induced abortion?
Medications used in induced abortion work by:
- Blocking progesterone (e.g., mifepristone)
- Stimulating uterine contractions (e.g., misoprostol)
- Softening and dilating the cervix (e.g., laminaria)
These medications disrupt pregnancy by:
- Terminating fetal development
- Inducing uterine contractions to expel the fetus
- Preparing the cervix for abortion
- What are the potential complications of induced abortion?
Potential complications of induced abortion include:
- Infection and sepsis
- Hemorrhage and blood loss
- Uterine perforation
- Cervical damage
- Asherman syndrome (uterine scarring)
- Infertility and reproductive complications
- Psychological trauma
- Failed abortion (continued pregnancy)
- Cardiac complications (rare)
It’s crucial to access safe and legal abortion services to minimize risks.
