Obstetrics Complications
SCHOOL OF HEALTH AND PUBLIC SAFETY
- Focus: Obstetrics Complications.
SUBSTANCE ABUSE
Tobacco Use:
- Effects:
- Decreased fetal growth.
- Increased risk of spontaneous abortions.
- Increased Sudden Infant Death Syndrome (SIDS) deaths.
- Increased risks of premature rupture of membranes.
- Increased risks of premature labor.
- Note: Secondhand smoke poses similar risks to the mother.
- Vaping: Current data on effects is absent.
Medication Use:
- Category C medications: Not recommended as they can remain in the fetus’s system longer than in the mother's.
- Example: A medication might last 4-5 hours in the mother but up to 7 days in the fetus.
- Many pregnant women avoid medication due to risks.
- Consideration: Evaluate if the benefits outweigh the risks.
PREMATURE LABOR
- Defined as occurring before 37 weeks of gestation.
- Potential causes include:
- Abnormal placenta, cord, or membranes.
- Substance abuse (smoking/vaping).
- Trauma or unknown factors.
- Maternal health issues (cardiac, renal, infections, diabetes).
- Common complications:
- Higher incidence of breech delivery.
- Risk remains elevated in subsequent pregnancies.
- Diagnosis made in the hospital by observing cervical changes.
SPONTANEOUS ABORTION (MISCARRIAGE)
- Definition: Termination of pregnancy before the 20th week of gestation.
- Differential diagnosis includes miscarriage.
- Symptoms: Includes cramping, abdominal pain, backache, and vaginal bleeding resembling intensified menstrual complaints.
- Emotional support is crucial.
ELECTIVE ABORTION
- Definition: Termination of pregnancy before the 20th week, sometimes up to the 28th week.
- Can be self-induced with herbal preparations.
- Risks of complications include hemorrhage or sepsis due to retained fetal/placental parts.
STAGES OF ABORTION
Threatened Abortion: Vaginal bleeding during the first half of pregnancy; may either progress or subside.
- Patients can continue normal activities.
Inevitable Abortion: Cannot be prevented, with severe abdominal pain and cervical dilation.
Incomplete Abortion: Some products remain in the uterus; be cautious of shock and collect all products for evaluation at the hospital.
Missed Abortion: Fetus dies before 20 weeks but remains in utero; transport is necessary with emotional support.
PLACENTA PREVIA
- Abnormal placement of the placenta in the lower uterine segment.
- Key signs include painless vaginal bleeding in the third trimester.
- Definitive management typically requires delivery via C-section.
ABRUPTIO PLACENTA
- Description: Premature separation of a normally implanted placenta after the 20th week.
- Complications include hypovolemic shock, renal failure, and fetal hypoxia.
- Symptoms: Sudden onset of severe abdominal pain, possible vaginal bleeding, and rigid uterine palpation.
UTERINE RUPTURE
- Risks include close pregnancies or previous surgical history (e.g., cesarean).
- Symptoms: Severe sharp pain, potential shock, and abnormal uterine shape.
HYPERTENSION IN PREGNANCY
- Chronic Hypertension: Blood pressure of 140/90 mm Hg or higher before 20 weeks.
- Gestational Hypertension: High blood pressure diagnosed after 20 weeks without systemic involvement.
PRE-ECLAMPSIA/ECLAMPSIA
- Pathophysiology is poorly understood but involves uteroplacental perfusion issues leading to widespread placental ischemia.
- Risk factors include previous cases of pre-eclampsia, multiple gestations, obesity, and advanced maternal age.
- Symptoms include hypertension, proteinuria, and peripheral edema.
- Warning signs of disease progression to eclampsia can include severe headaches, liver impairment, and visual disturbances.
HELLPS SYNDROME
- A severe variant of pre-eclampsia affecting the liver and blood. Symptoms vary and may include malaise, abdominal pain, and blurred vision.
DIABETES IN PREGNANCY
- Hormonal changes can lead to unstable blood glucose levels.
- Gestational Diabetes: Managed through diet and medication; there's a risk for long-term diabetes development post-pregnancy.
PULMONARY EMBOLISM AND TRAUMA
- Major concerns for maternal mortality during and after childbirth; sudden onset of symptoms such as dyspnea and tachycardia should raise suspicion.
- Maternal trauma must be approached carefully due to physiological changes that can complicate assessment and treatment.
VULNERABILITY OF PREGNANT WOMEN AND FETUS TO TRAUMA
- Pregnancy leads to physiological changes that increase vulnerability to trauma.
- Close monitoring of the fetal heart rate post-trauma is essential; normal rates range from 120 to 160 beats/minute.
- Patient ABCs (Airway, Breathing, Circulation) remain the highest priority in treatment.
