Threatened Abortion: Definition, Causes, Signs And Symptoms, Investigation, Management, And Nursing Interventions

What is Threatened Abortion?

is when the pregnancy is threaten to com out .Bleeding from the vagina before 20 weeks of pregnancy with a closed cervix and a living fetus.

Chromosomal abnormalities (most common cause).Faults in the fetus’ genetic material lead to poor implantation or early pregnancy instability.
Hormonal imbalance,Low progesterone to maintain pregnancy
Uterine abnormalities uterine septum, or adhesions reduce space and interfere with normal implantation.
Infections,Cervical or vaginal infections (e.g., cervicitis,uti) can irritate tissues and trigger bleeding.
Subchorionic hemorrhage,Bleeding between placenta and uterine wall this may threaten pregnancy.

maternal age (>35 years) Higher risk of chromosomal errors in pregnancy.
Previous miscarriage history,Indicates possible underlying reproductive or hormonal issues.
Chronic medical diseases,Diabetes, thyroid disorders, and hypertension affect fetal development and implantation.
Lifestyle factors,Smoking, alcohol, drug use, and poor nutrition increase pregnancy complications.
Physical and emotional stress,Heavy workload, trauma, or severe stress may worsen pregnancy stability.
Poor antenatal care,Late booking delays detection and management of early pregnancy complications.

Vaginal bleeding,Usually the earliest sign, ranging from light spotting to moderate bleeding.
Lower abdominal pain / cramping,Mild to moderate pelvic cramps similar to menstrual pain.
Low back pain,Aching pain due to uterine irritation
Feeling of pelvic heaviness,A sensation of pressure in the lower abdomen.
Pregnancy symptoms is still be present,Nausea, breast tenderness, and fatigue may continue because pregnancy is still viable.
Closed cervix on examination

History taking.Ask about bleeding, pain, gestational age, and obstetric history.ask about the onset,duration and characteristic
Physical examination,Check vital signs and do abdominal/pelvic examination
Ultrasound scan.Confirms intrauterine pregnancy and fetal heartbeat/viability.
Serum β-hCG levels.Serial measurements assess whether pregnancy is progressing normally.
CBC).Checks for anemia and platelet.
Blood group and Rh factor,Determines need for Anti-D in Rh-negative mothers.

Expectant (watchful waiting) management.Most cases are observed because pregnancy can still continue normally.
Bed rest / reduced physical activity,Helps reduce uterine irritation and may decrease bleeding episodes.
Avoid sexual intercourse,Prevents further cervical or uterine stimulation during bleeding.
Progesterone therapy (selected cases).May support the uterine lining when deficiency is suspected.
Treat underlying cause.Manage infections or control chronic conditions like diabetes or thyroid disease.
Pain management.Paracetamol can be used; avoid NSAIDs unless prescribed.
Patient reassurance and counseling.Reduces anxiety since many pregnancies still progress normally.
Follow-up monitoring,Repeat ultrasound and clinical review to assess fetal viability.
Emergency advice,Return immediately if heavy bleeding, severe pain, dizziness, or tissue passage occurs.

Initial assessment.Assess bleeding, pain, and gestational age; check vital signs for stability.
Monitoring of vitals and maternal condition.Regularly monitor BP, pulse, temperature, and signs of worsening condition.
Observation of vaginal bleeding,Record amount, color, and clots; use pads for accurate measurement.
Pain management,Give prescribed analgesics like paracetamol and monitor pain relief.
Bed rest and positioning,Encourage rest and reduced activity to minimize uterine irritation.
Infection prevention,Maintain aseptic technique during examinations and monitor for fever or foul discharge.
Emotional support,Reassure the mother and reduce anxiety by explaining the condition simply.
Medication administration,Administer prescribed drugs (e.g., progesterone) and Anti-D if Rh-negative.
Health education,Teach danger signs and advise avoidance of intercourse, smoking, alcohol, and heavy work.
Follow-up care,Ensure regular antenatal visits and ultrasound monitoring of pregnancy progress.

Progression to miscarriage,The pregnancy may continue to inevitable, incomplete, or complete abortion.
Anemia,Ongoing vaginal bleeding can lead to reduced hemoglobin levels.
Infection,Retained products or prolonged bleeding may increase risk of uterine infection.
Emotional and psychological distress,Anxiety, fear, and depression due to uncertainty of pregnancy outcome.
Preterm complications (later pregnancy),Increased risk of preterm labor or placental problems in some cases.

threatened abortion is Vaginal bleeding before 20 weeks with a closed cervix and a viable fetus

Most commonly chromosomal abnormalities, hormonal imbalance, and uterine or infection

Vaginal bleeding, mild lower abdominal pain, and back pain.
