Mô tả chi tiết
137
DEFINITION
The termination of a pregnancy medically or operatively before fetal viability;
definition of viability varies from state to state
ASSESSMENT OF THE PATIENT
Physical assessment is crucial before an elective abortion:
Ultrasound should be performed if there is a discrepancy between dates
and uterine size.
Patient’s blood type and Rh type must be evaluated; if Rh negative,
RhoGAM should be administered prophylactically.
Careful patient counseling should be performed.
TYPES OF INDUCED ABORTION
Elective voluntary: Interruption of pregnancy at the request of the mother
Therapeutic: Interruption of pregnancy for the purpose of safeguarding the
health of the mother
INDICATIONS FOR THERAPEUTIC ABORTION
Maternal Indications
Cardiovascular disease
Genetic syndrome (e.g., Marfan’s)
Hematologic disease (e.g., TTP)
Metabolic (e.g., proliferative diabetic retinopathy)
Neoplastic (e.g., cervical cancer; mother needs prompt chemotherapy)
Neurologic (e.g., Berry aneurysm; cerebrovascular malformation)
Renal disease
Intrauterine infection
Severe preeclampsia/eclampsia
HIGH-YIELD FACTS IN
Induced Abortion
Abortion may not be denied
in first 3 months of
pregnancy in any state.
Fetal Indications
Major malformation (e.g., anencephaly)
Genetic (e.g., Tay–Sachs disease)
METHODS OF ABORTION
First Trimester
MEDICAL
Antiprogesterones such as mifepristone (RU 486) or epostane; used
only before 9 weeks’ gestation. Without progesterone, the uterine lining
sloughs off.
Methotrexate IM + intrauterine misoprostol 1 week later; used only before 9 weeks’ gestation. Methotrexate is a folic acid antagonist that interferes with cell division.
SURGICAL
Cervical dilation followed by aspiration curettage (D&C): Risks include cervical/uterine injury and Asherman’s syndrome.
Second Trimester
MEDICAL
Intravaginal prostaglandin E2 (PGE2) or PGF2α with urea
SURGICAL
Dilation and evacuation
Complications of Surgical Abortions
Infection
Incomplete removal of products of conception (POC)
Disseminated intravascular coagulation (DIC)
Bleeding
Cervical laceration
Uterine perforation/rupture
Psychological sequelae
Death

HIGH-YIELD FACTS Induced Abortion
What abortion method has
the lowest complication
rate? Dilation and
evacuation. Risks include:
Hemorrhage/perforation.
Medical methods of
abortions can only be used
in first 9 weeks.
LESS COMMON METHODS OF ABORTION
Medical
Intra-amnionic infusion of hyperosmolar fluid (saline + urea)
High-dose IV oxytocin (induces uterine contractions)
Surgical
Hysterotomy is used only if other methods have been unsuccessful.
A hysterotomy is a C-section of a preterm fetus.
Hysterectomy
139
HIGH-YIELD FACTS Induced Abortion
Infection is the most
common complication of
hysterectomy.
Death is a risk of abortion,
but it is 10 times less
than the risk of death from
giving birth.
