woman with an abortion
 State the complications that can occur due to
an abortion

INTRODUCTION
 Uterine abortion is the commonest cause
of vaginal bleeding in early pregnancy
 It complicates 10-15% of all pregnancies
 However bleeding in early pregnancy can
be caused by other pregnancy
complications such as ectopic pregnancy,
and molar pregnancy being the most
serious

INTRODUCTION contd…
Others are;
 Mucous polyp
 Carcinoma
 Vulva or vaginal lesions e.g. varicose veins

INTRODUCTION contd…
 All these conditions may cause bleeding in early
pregnancy
 Abortion is important not only because of the
loss of the wanted pregnancy, but because it’s
an important cause of maternal death from the
haemorrhage and sepsis which may follow a
mismanaged abortion
 Abortion accounts for 95% of cases of bleeding
in early pregnancy.

Definition
 Abortion is an expulsion of products of
conception before the 28th week of
gestation and before viability of the fetus
(Hossan 1982)
 Abortion is loss of pregnancy before the
28th week or loss of fetus weighing less
than 500g (WHO)

Definition contd…
 An abortion can either be induced or
spontaneous
 Induced abortions may be therapeutically
indicated or elective that is for either
social or personal reasons
 Spontaneous abortions start because of
some physiological cause

CAUSES OF ABORTION
 There are recognizable factors that
predispose a woman to spontaneous
abortion;
 Chromosomal anormalies: account for
50-60% for early spontaneous abortions
 These may either involve number of
chromosomes, monosomy,trisomy, triploidy
or structural defects e.g. translocation,
inversion e.t.c. (Kajii, Ferrier etal, 1980).

CAUSES OF ABORTION contd…
 Noxious agents e.g. viruses,
chemicals, cytotoxic drugs, radiation
may be embryotoxic
 Maternal infections: several agents
have been suspected e.g. listeria
monocytogenes, mycoplasma hominis,
urea plasma urealyticum, malaria e.t.c.

CAUSES OF ABORTION contd
 Maternal chronic disease:
tuberculosis, sickle cell disease, chronic
renal disease, hypothyroidism.
 Abnormalities of the generative
organs e.g. retroversion or prolapse,
incompetent cervix, congenital
abnormalities of the uterus e.g. septate
uterus, bicornuate uterus.

 Unsuccessful implantation: subtle
changes in the delicate processes that lead to
successful implantation may cause early
abortion e.g. abnormalities in the hormonal
control of tubal motility or development of
the decidua e.t.c.
 Abdominal surgery: trauma of surgery may
initiate abortion e.g. myomectomy,
appendicitis or peritonitis (laparatomy)

 Other causes;
 Advanced maternal age
 Poor obstetric history
 Infertility
 Concurrent medical disorders like diabetes
mellitus, cystic fibroids, and systemic lupus
erythematosus.

 In a way causes of abortion can be
classified into maternal and fetal causes as
they have been tabulated above
 Often the cause of abortion cannot be
found
 And fetal causes are the commonest
cause of early abortion in cases of fetal
abnormalities

CLINICAL TYPES OF ABORTION
SPONTANEOUS
 Threatened
 Inevitable
 Complete
 Incomplete
 septic
 Missed
 Habitual

CLINICAL TYPES OF ABORTION contd…
INDUCED
 Therapeutic
 Septic
 Complete
 Incomplete

CLINICAL TYPE PRESENTATION
1. THREATENED ABORTION
 Per vaginal bleeding of uterine origin
 Cervix is closed
 Bleeding may be heavy or slight
 Intermittent or continous bleeding
 May or may not be accompanied by mild
cramping and back pain
 Pregnancy test is usually positive

CLINICAL TYPE PRESENTATION contd…
2. INEVITABLE ABORTION
 Progressive dilatation of the cervix
 Pregnancy is more advanced < 12 weeks
 Bleeding is heavier
 Abdominal pain is more severe, colicky in nature and
situated in the supra pubic area
 Amniotic membranes may be felt bulging into the
cervical canal or may be already ruptured and fetal
parts palpable
 May be complete or incomplete

contd
3. COMPLETE ABORTION
 The term “complete abortion” signifies that all
products of conception have been expelled.
 Uterus becomes smaller on palpation
 On vaginal examination cervix is closed
 Patient usually notices expulsion of the tissue or even
fetus and placenta
 Abdominal pain subsides
 Bleeding may stop or slows down considerably

contd…
4. INCOMPLETE ABORTION
 Expulsion of products of conception is
incomplete
 Abdominal pain continues although may
be less severe
 Bleeding continues and becomes heavier
 Uterus enlarged, palpable and may feel
boggy

contd
5. INCOMPLETE ABORTION contd…
 Cervix may either be dilated or closed,
but will feel patulous
 Signs of shock if severe bleeding
 Placenta and fetus may appear to have
been expelled intact, but some
trophoblastic or placental tissue remain
adhering to the uterine wall causing
profuse bleeding
 Products of conception may be felt or seen

contd
6. MISSED ABORTION
 Refers to cases in which dead fetus or
embryo has been retained in the uterus
for more than 4-8weeks
 After period of normal pregnancy the
fetus dies
 This may or may not be heralded by
vaginal bleeding or abdominal pain

contd
MISSED ABORTION contd…
 Vaginal bleeding stops and patient
continues to be ammenorrheic
 In some other cases vaginal bleeding
continues intermittently and usually is
dark brown discharge
 Fetal movements if felt before ceases

contd
MISSED ABORTION contd…
 Symptoms of early pregnancy begin to
disappear
 Uterine size remain stationery or even
decreases
 Cervix is closed
 Fetal heart cannot be heard by either
fetoscope or Doppler
 Pregnancy test usually is negative

contd
MISSED ABORTION contd
 process of abortion will eventually start
spontaneously 4-5 weeks
 The main complication of missed abortion
is development of Disseminated
Intravascular Coagulation (DIC)
 Patient notices gum or nose bleeding or
bleeding may occur after mild trauma
(cutaneous ecchymoses)

contd
7. SEPTIC ABORTION
 Infection can complicate any type of abortion
 If the infection is disseminated into the
maternal systemic circulation it is usually called
septic.
 Illegal (criminal) abortion used to be the cause
of septic abortion
 The risk to the patient was not only from the
sepsis (unsterile instruments or environment)
but also from possible associated injuries to
the birth canal.

contd
SEPTIC ABORTION contd..
 Per vaginal bleeding with pain
 Amount of bleeding is variable and pain is
suprapubic constant and severe
 Patient feels weak and complains of
headache, malaise and seem to be
extremely ill

contd
 Chills and fever signifies serious infection
 Most serious complications of septic
abortion is septic shock characterized by
hypotension with tachycardia, normal or
subnormal temperature
 Generalized abdominal tenderness with
rebound tenderness, rigidity or distension
are signs of spreading peritonitis

contd
 On vaginal examination cervix is open with
foul smelling purulent bloody vaginal
discharge
 Products of conception may be felt in
cervical canal or inside the uterine cavity
 Cervical motion elicits severe tenderness

contd
8. HABITUAL ABORTION
 A woman who has had three or more successive
abortions is called a habitual aborter.
 In the majority of patients no obvious causes
can be found.
 However some of the known causes are chronic
illness, such as diabetes mellitus, and abnormalities
such as a septate uterus and cervical incompetence
 These women should always be referred to the
hospital.

IMMIDIATE MANAGEMENT OF ABORTION
THREATENED ABORTION
 Obtain history and do physical
examination and vital observations for
diagnosis, assessment, and base line data.
 Bed rest is the most important form of
treatment. The patient should remain in
bed for 5-7days or for as long as blood is
bright red. Bed rest increases blood flow
to the placenta and reduces pain.

IMMIDIATE MANAGEMENT OF
ABORTION contd..
THREATENED ABORTION contd..
 Give mild sedatives e.g. phenobarbitone 60mg
8hourly to enable patient rest in bed
 If uterine contractions become stronger,
analgesics such as pethidine100mg
intramuscularly or morphine 15mg may be
needed.
 Pads should be saved in order to help assess the
amount of blood loss. Report any increase in
bleeding or pain.

ABORTION contd..
COMPLETE ABORTION
 Rest in bed, if possible with sedation
 Evacuate uterus as soon as possible to
ensure completeness
 Check Hb after 24hours
 Curettage only needed if bleeding persists

ABORTION contd..
INCOMPLETE ABORTION
 Evacuate uterus under anesthesia or
strong analgesia
 Replace blood if necessary
 Antibiotics only if febrile
 Set up pitocin drip
 If patient is in shock start a plasma
expander drip after taking blood for
grouping and cross-matching

ABORTION contd
INCOMPLETE ABORTION contd..
 Do a sterile vaginal examination and remove any
placental tissue distending the cervix with a
finger or sponge forceps
 Give ergometrine 0.5mg intramuscularly. Once
these steps have been taken the condition
usually improves and the patient can safely be
transferred to hospital.
 N.B Do not transfer a shocked patient to
hospital; Resustate first.

ABORTION contd
SEPTIC ABORTION
 Treatment of these patients with septic
abortion is an emergency as delay may
result in severe complications or death
 Patients should be managed in the
hospital if possible, however treatment
should be instituted as soon the diagnosis
is made

ABORTION contd
 Resustate with intravenous fluids
 Give parenteral broad spectrum antibiotics
 Take a cervical swab for culture and
sensitivity before starting antibiotic
treatment
 Blood transfusion can be given in cases of
low haemoglobin

ABORTION contd
 Most patients will have fluid deficit from
blood loss during abortion or from poor
fluid intake due to ill health
 Evacuation of the uterus should be
instituted immediately resustation is
complete and antibiotics started

ABORTION contd
 MISSED ABORTION
 Wait up to one month for bleeding to
commence
 There is poor response to pitocin
 Refer cases of missed abortion to hospital
for surgical evacuation and checking of
uterus may be necessary

COMPLICATIONS OF ABORTION
 Severe vaginal bleeding due to retained
products of conception
 Shock due to bleeding
 Secondary bacterial infections due to use
of unsterile instruments to abort or from
an endogenous infective organism

COMPLICATIONS OF ABORTION
contd..
 Peritonitis
 Uterine rupture
 Bacteremia
 Anaemia

CONCLUSION
 We have discussed abortion and we said that
abortion is the expulsion of products of
conception before the 28th week of gestation.
 An abortion can either be induced or can start
spontaneously.
 Causes of abortion can either be maternal or
fetal, but there are cases where the cause is not
known.
 We also looked at various clinical types of
abortion such as incomplete, complete and
others.
 All cases of abortion should be considered
incomplete until a thorough investigation is done
 They should be treated as an emergency
