Abortion has become rampant all over the world. It is a
common issue among the teenagers and adult women in
the society. Issues relating to abortion has been on and
generated a heated argument and distressing statistics
concerning abortion have been documented. The peak
time for abortions is between 6-12th week of pregnancy
when the level of progesterone secreted by the corpus
luteum falls and the placental hormone has not reached its
sufficiently high level to sustain the conceptus.
Definitions of abortion vary across and within countries as
well as among different institutions.
What is abortion?
-Abortion is the interruption of pregnancy before the
28th week, after which the fetus is said to be viable(
- Abortion is the expulsion of the conceptus before 20-
22 completed weeks of gestation, or a fetus weighing
less than 500g.( WHO)
Types of Abortion
MOLE COMPLETE INCOMPLETE
May go to term
-Disease or mal-development of the ovum and the
-Defective implantation of the trophoblast which
results in the inability to synthesize progesterone.
-metabolic disorders such as DM, anemia, thyroid
disease, renal disease and/or failure, hypertensive
-acute infections such as influenza, rubella, malaria.
-uterine abnormalities: myomas, bi-cornuate uterus,
double uterus and vagina. Infantile uterus ,fibroids
-cervical incompetence caused by
trauma due to previous D & C or cone
-extreme emotional stress result in the
release of pituitary hormones which
affect uterine function.
-certain toxic drugs and substances e.g.
anesthetic gases, antimetabolic drugs,
oxytocics and herbs.
ABO and Rhesus incompatibility.
Spontaneous abortion / miscarriage: This is
commonly referred to as miscarriage. It occurs when
pregnancy ends before the baby has any chance of
survival. Most spontaneous abortion occurs in the
first 12 weeks of pregnancy. Spontaneous abortion
can be divided into
Blood mole and carneous mole

Management of a threatened
- Reassurance of patients
- Rest for few days until the bleeding
has settled down
- may require progesterone
- folic acid
- anti D if RH negative
Missed abortion: an abortion that occurs
when the fetus dies and is retained in utero,
together with the placenta and membranes.
Signs and symptoms
- Disappearance of symptoms of pregnancy
-Size of uterus < duration of gestation
- U/S shows no signs of fetal life
Management of missed
-blood sample for plasma fibrinogen to rule
-uterine evacuation if less than 12 weeks
-give oxytocin or prostaglandin infusion if
patient is more than 12 weeks pregnant.
This is a condition that occurs as a
complication of a missed abortion. The
ovum dies in utero, and the decidua
capsularis remains intact. The zygote is
surrounded by layers of blood, due to
bleeding between the gestational sac and
the uterine wall.
Signs and symptoms of
-usually occurs before 12 weeks of
-brownish vaginal discharge
-signs of pregnancy disappear
-uterus larger than dates.
-cramping lower abdominal pains
Management of blood mole
-evacuation of the uterus if less than 12
-give oxytocics or prostaglandins to
abort the mole if condition is diagnosed
after 12 weeks pregnant
This is a molar pregnancy that is formed
when fluid drains from a blood mole. It’s a
fleshy, firm, hard mass.
Management: the clinical features and

- blood sample for blood group, RH factor,
- removal of POC if felt in cervical canal
- ergometrine 0.5mg IV or IM to ↓ blood
- IV fluids with or without blood
-antibiotics and analgesics
-sedation to relieve anxiety
HABITUAL OR RECURRENT
This occurs when a patient has experienced 3
or more consecutive spontaneous abortions,
usually after 14 weeks gestation. There is
usually no warning signs but the sudden
rapture of membranes and expulsion of
abortus occurs after a gradual painless dilation
of the internal cervical os. The cause is usually
mechanical e.g. uterine abnormality or cervical
incompetence. May also be due to
psychological, immunological, infective, or
chromosomal causes. Manage the patient
Threatened Abortion Inevitable
This is the deliberate termination of pregnancy
for various reasons such as threat to the life of
the pregnant woman or for social reason. It can

measures are always taken. The consent
of the medical superintendent, patient and
her husband or guardian if less than 18 is
required by law.
Procedures used in
Vacuum Aspiration-uterus is vacuumed
with a syringe through a dilated cervix to
remove conceptus, placenta and
endometrial tissue. Also called menstrual
