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.
