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*
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:
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:
3. Incomplete Abortion:
An incomplete abortion occurs when parts of the products of conception are expelled, but others remain inside the uterus.
Symptoms include:
4. Missed Abortion:
A missed abortion, also known as a missed miscarriage, occurs when the fetus dies but remains inside the uterus.
Symptoms include:
5. Complete Abortion:
A complete abortion occurs when all products of conception are expelled from the uterus.
Symptoms include:
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
Fetal abnormalities, also known as congenital anomalies, can contribute to spontaneous abortion in several ways:
These abnormalities can disrupt normal fetal development, leading to:
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:
An incompetent cervix can cause:
4. How do chronic illnesses increase the risk of spontaneous abortion?
Chronic illnesses can increase the risk of spontaneous abortion by:
Examples of chronic illnesses that may increase the risk of spontaneous abortion include:
5. What is the impact of trauma on spontaneous abortion?
Trauma, physical or emotional, can increase the risk of spontaneous abortion by:
Types of trauma that may contribute to spontaneous abortion include:
THREATENED ABORTION
Symptoms
y Scanty to moderate painless vaginal bleeding y Mild pelvic discomfort
Signs
y The uterine size is compatible with the gestational age
y There is no cervical effacement or dilatation
Investigations
y FBC and sickling
y Ultrasoundscan(toconfirmviablefoetusinuterowithclosedcervix) y Other investigations for potential underlying causes e.g. malaria
Treatment Treatment objectives
y There is no cervical effacement or dilatation
Investigations
y FBC and sickling
y Ultrasoundscan(toconfirmviablefoetusinuterowithclosedcervix) y Other investigations for potential underlying causes e.g. malaria
Treatment Treatment objectives
y To maintain a viable pregnancy to term if possible
Non-pharmacological treatment
y Bed rest at home or hospital
y To abstain from sexual intercourse
y To report back if bleeding or pain increases
Pharmacological treatment
y No specific treatment required
y Treat any underlying illnesses e.g. malaria
INEVITABLE ABORTION
Symptoms
y Lower abdominal pain
y Heavy vaginal bleeding
y No foetus or products of conception passed per vagina y Painless loss of liquor per vaginam
Signs
y The cervix is dilated with the membranes bulging
y There may be loss of liquor
y The uterine size is compatible with the gestational age
y There may be signs of shock pallor, collapsed peripheral vessels,
rising pulse with reducing volume, falling BP and cold clammy skin
Investigations
y FBC and sickling
y Blood grouping and cross matching
y Ultrasound scan (shows the foetus dead or alive)
y Cervix may be dilated with membranes bulging through it
y In instances associated with loss of liquor there may be
oligohydraminios
y Ultrasound is necessary only if the diagnosis is in doubt
Treatment
Treatment objectives
y To resuscitate patient and/or prevent shock
y To relieve pain
y To allow the patient to abort (assist uterine contractions if weak) y To evacuate the retained products of conception from the uterus.
y To determine cause of abortion if recurrent
y To prevent infection with antibiotic prophylaxis
y To prevent risk of Rhesus incompatibility in future pregnancies
Non-pharmacological treatment
y Evacuationofth euterusisdonebyeitherofthefollowingtechniques after the expulsion of the foetus or before the expulsion of the foetus if it is less than 12-14 weeks size
y Manual Vacuum Aspiration (MVA) with or without paracervical Or block anaesthesia
y Uterine curettage under paracervical block or general anaes- thesia (Gestations 12 weeks or less
y Uterine evacuation under anaesthesia especially when the uterine size is larger than 12 weeks size
Pharmacological treatment
A. If patient is in shock
or bleeding is severe
y IV fluids and blood transfusion as necessary
B� To relieve severe pain
y Morphine, IV, 2.5-5 mg 4 hourly as required And
Or
Evidence Rating: [C]
y Metoclopramide, IV, 5-10 mg 8 hourly as required for vomiting
y Pethidine, IM, 75-100 mg stat. Then
50-100 mg 6-8 hourly if required
And
y Promethazine, IV/IM, 25 mg as required (max. 25 mg 6 hourly) as required to reduce the chances of vomiting and to potentiate the analgesic effect of Pethidine
C� Evacuate uterus
If uterine size > 12-14 weeks Evidence Rating [A]
y Oxytocin, IV, 10-20 units per litre of Normal saline Or
Uterine size <12 weeks Evidence Rating: [C]
y Misoprostol, oral/SL, 600 microgram stat.
D. To Prevent Infection
y Amoxicillin, oral, 500 mg 8 hourly for 5-7days And
y Metronidazole, oral, 400 mg 8 hourly for 5-7days
E. To prevent Rhesus Isommunization in Rhesus negative women
y Anti D Rh Immune Globulin, IM, 300 microgram (1,500 Units), stat. within 72 hours of abortion
