dr Irma Savitri Abortus PART 1

Summary

Dr. Irma Safitri, a specialist in obstetrics and gynecology, discusses various types of spontaneous abortion, focusing on imminent, incomplete, and complete abortions. She explains the causes, mechanisms, and diagnostic methods for these conditions, emphasizing their occurrence in the first trimester. The lecture also covers the different risk factors such as chromosomal anomalies, maternal health issues like diabetes, obesity, and infections, as well as paternal factors like age. Dr. Safitri elaborates on the clinical symptoms and diagnostic procedures, including the use of ultrasound, to assess pregnancy loss.

Takeaways

• 😀 Abortus is defined as pregnancy loss before 20 weeks or when the fetus weighs less than 500 grams, according to WHO and National Centers for Health Statistics.
• 😀 Spontaneous abortion is most common in the first trimester, with around 80% of cases occurring within the first 12 weeks of pregnancy.
• 😀 Three types of spontaneous abortion are discussed: abortus iminens (threatened), abortus incomplete (incomplete), and abortus complete (complete).
• 😀 Abortus iminens involves vaginal bleeding, mild cramps, and a closed cervix, with the potential to progress to a complete abortion if untreated.
• 😀 Abortus incomplete is characterized by heavier bleeding, abdominal pain, a partially open cervix, and retained pregnancy tissue.
• 😀 Abortus complete refers to the full expulsion of pregnancy tissue, followed by reduced bleeding and a closed cervix.
• 😀 The primary cause of spontaneous abortion, especially in the first trimester, is chromosomal abnormalities, accounting for about 50% of cases.
• 😀 Risk factors for spontaneous abortion include maternal age (over 35 years), extreme youth (under 20 years), and certain health conditions like diabetes, obesity, and smoking.
• 😀 Genetic abnormalities such as trisomy, monosomy, and triploidy are common fetal causes of miscarriage, particularly in early pregnancy.
• 😀 Diagnostic methods for abortion include patient history, physical examination, ultrasound, and genetic tests if there are recurrent miscarriages.
• 😀 The pathophysiology of abortion involves bleeding, tissue necrosis, uterine contractions, and the eventual expulsion of fetal material.

Q & A

What is the definition of abortion according to the National Center for Health Statistics and WHO?

Abortion is defined as the termination of pregnancy before the fetus reaches 20 weeks of gestation or if the fetus weighs less than 500 grams. If the fetus weighs more than 500 grams, it is generally classified as premature labor rather than abortion.

What are the primary causes of spontaneous abortion during the first trimester?

The main cause of spontaneous abortion in the first trimester is chromosomal abnormalities, accounting for around 50% of cases. Most of these abnormalities are due to errors during gametogenesis, with 95% of cases being maternal and 5% paternal.

How can anamnestic findings help in diagnosing types of abortion?

Anamnestic findings, such as the presence of vaginal bleeding, pain, and cervical changes, can help differentiate between types of abortion. For example, in threatened abortion (abortus imminens), bleeding occurs but the cervix remains closed, while in incomplete abortion, the cervix opens and there may be tissue expulsion.

What are the common types of spontaneous abortion discussed in the presentation?

The presentation focuses on three types of spontaneous abortion: threatened abortion (abortus imminens), incomplete abortion (abortus spontan incomplete), and complete abortion (abortus spontan complete).

What role do chromosomal abnormalities play in abortion?

Chromosomal abnormalities are responsible for up to 75% of abortions that occur within the first 8 weeks of pregnancy, particularly conditions like trisomies, monosomies, and triploidy. These genetic abnormalities prevent the fetus from developing normally and result in miscarriage.

How is incomplete abortion diagnosed and managed?

Incomplete abortion is characterized by heavier vaginal bleeding, pain, and the presence of an open cervix. Ultrasound is used to detect retained tissue, and management often involves removing the remaining tissue either through medical or surgical means.

What are the differences between threatened abortion and complete abortion?

In threatened abortion, bleeding occurs with mild cramping, but the cervix remains closed, and pregnancy may still continue. In complete abortion, all pregnancy tissue, including the fetus and placenta, is expelled, and the cervix closes, with bleeding gradually decreasing.

What factors contribute to spontaneous abortion in older and younger women?

Women under 20 and over 40 have higher risks of spontaneous abortion. Younger women, especially teenagers, have an increased risk due to developmental factors, while older women experience a higher risk due to chromosomal abnormalities and other age-related health conditions.

What are the maternal factors that can lead to abortion?

Maternal factors include infections (viral, bacterial, or parasitic), pre-existing medical conditions (such as diabetes, obesity, and thyroid disorders), cancer, surgical history, poor nutrition, and lifestyle factors like smoking.

How do environmental factors contribute to abortion?

Environmental factors, particularly exposure to toxic substances or harmful materials in the workplace, can increase the risk of spontaneous abortion. Such exposure may interfere with fetal development or increase the likelihood of miscarriage.
