Abnormal Pregnancy

A child's fetus is considered viable at 28 weeks of gestation.
Recent findings suggest viability may now be recognized at 20 weeks.
A weight threshold of 500 grams is commonly referenced, but there are concerns regarding this standard, particularly with respect to fetuses from diabetic mothers who may weigh 500 grams yet still exhibit health issues.

Abortion can be classified into different types, each necessitating a clear understanding of definitions and explanations.

Corresponds to a clinical situation where there is vaginal bleeding before 20 weeks of gestation.
Accompanied by uterine contractions and may signal an impending miscarriage.
The use of the term "miscarriage" is more common in lay language.
Can result in either a complete or incomplete abortion or may evolve to a missed abortion.

Occurs when the miscarriage is unavoidable.
Can be either:
- Complete: where all products of conception are expelled.
- Incomplete: where not all products are expelled.

Refers to a situation where the fetus dies, but signs of pregnancy (such as bleeding) recede.

Includes two categories:
- Legal Abortion: Carried out under specific regulations set forth by the state; requires confirming that the woman's life would be at risk if the pregnancy continues.
- Illegal/Criminal Abortion: Performed under circumstances that violate the law, might involve unlicensed practitioners.

The discussion involves views on whether a fetus, deemed not to have human rights, justifies termination. A metaphor about farming illustrates the point: if crops are destroyed before harvest time, there is nothing left to yield.
Repeatedly, questions are posed about the nature of what is aborted—arguing against the terminologies used to diminish the fetus’s status (e.g., "blood clot" instead of fetus).

Genetic factors, endocrine and metabolic abnormalities, infections, environmental factors, and unexplained issues can lead to abortion.
Specific emphasis on immunologic disorders and incompatibility issues.
- Antifetal Antibodies: These can develop when maternal and fetal blood types are incompatible, leading to complications in pregnancy.
- Premature Rupture of Membrane (PROM): This can initiate a sequence of events leading to abortion due to loss of protective amniotic fluid.

Before 8 Weeks:
- The ovum, surrounded by the decidua, is expelled intact.
- If the cervical os fails to dilate adequately, this results in a cervical miscarriage.
8-14 Weeks:
- The fetus is expelled, but the placenta and membranes may remain in the uterus.
Beyond 14 Weeks:
- Similar to labor; the fetus is expelled first, followed by variable intervals before the placenta is expelled.

Symptoms include:
- Mild bleeding (possible spotting)
- Mild pain
- Cervical os is closed during examination.
Management includes bed rest and reassurance.

Heavy bleeding possible with clots, severe abdominal pain, and open cervical os.
Management includes intravenous fluids, potential transfusions, and evacuation of the uterus via medical or surgical techniques.

All products of conception expelled, with no further bleeding or abdominal pain.
Positive pregnancy test precedes diagnosis.
Requires ultrasound examination to confirm the absence of residual tissue.

Gradual disappearance of pregnancy symptoms, brownish discharge, and possibly a persistently positive pregnancy test for some time.
Absence of fetal heart sound or pulsation indicated via ultrasound.

Discussing Anti-D Gamma Globulin administration for resource negative women post-abortion to prevent future complications due to Rh incompatibility.
Emphasis on the need for complete evacuation of the uterus following any abortion to prevent complications such as infection or retained products.

Practices and policies regarding abortion management may vary between institutions.
Contextual practices should be adapted based on clinical findings and patient history, ensuring informed consent and adherence to ethical standards.
