(O) child at risk 2 ( exam 4)

Observation of Amniotic Fluid

• Assessment of fluid leaking during labor.
  • Questions to consider:
  • How long has fluid been leaking?
  • What color is the fluid?
  • Is there any odor?

Evaluation of Pregnant Patient

• Key questions to assess fetal status:
  • "How old is this baby?" (Gestational age)
  • Any signs of infection present?
  • How is the fetus tolerating the situation?
• Usage of sterile speculum for further examination.
  • To observe fluid flow from the cervix.
  • Assessment of cervical dilation's impact on fluid identification.

Confirming Amniotic Fluid

• Fluid identification methods:
  • Collecting fluid on slide, letting it dry, and examining under the microscope.
  • Observed patterns resemble frost on a window from salt crystals formed by dried amniotic fluid.
  • pH sensitive swab to distinguish between vaginal secretions and amniotic fluid.
  • Normal vaginal secretions are acidic; amniotic fluid is more basic.
  • Nitrazine swab procedure:
  • Bright yellow upon first taking out (indicates not amniotic fluid).
  • Dark greenish/blue indicates presence of amniotic fluid.
  • Color change indicates the pH being more basic than normal vaginal secretions.

Amnisure Test

• A non-invasive vaginal swab that can confirm amniotic fluid presence without sterile speculum.
  • Sample is sent to the lab for analysis.

Premature Rupture of Membranes

• Diagnosis:
  • If diagnosed with ruptured membranes, less than 37 weeks in gestation indicates preterm pre-labor rupture of membranes.
  • Major concern is infection as it poses high risk with acute management plan.
  • Focus on time for obtaining two doses of betamethasone to promote infant lung maturity.
  • Betamethasone:
    • Administered as two doses spaced 24 hours apart to enhance surfactant production in the fetus.
  • Consideration of using tocolytics to prevent contractions is assessed carefully due to infection risks.

Risk Assessment

• Signs of infection in the mother and baby:
  • Tachycardia in mother and baby.
  • Maternal fever present.
  • Foul-smelling amniotic fluid.

Complications of Multiple Gestation

• Incidence of twins.
  • Risk factors associated with multiple pregnancies outlined.
  • Increased risk of uterine distention leading to preterm delivery and complications.
  • Postpartum hemorrhage risks due to overstretched uterus.
• Comparison of Dizygotic versus Monozygotic twins:
  • Dizygotic twins come from two distinct eggs and sperm with separate placental structures.
  • Monozygotic twins are from one egg and sperm leading to shared placental structures, increasing risk factors.

Risks with Monozygotic Twins

• Sharing placental resources may lead to unequal distribution or twin-to-twin transfusion syndrome.
  • Twin-to-Twin Transfusion:
  • One twin (donor) loses resources, and one twin (recipient) receives excess resources.

Managing Delivery of Twins

• Delivery strategies outlined; higher risks require careful monitoring and planning, including the possibility of C-section for emergencies.
  • Identification of Baby A and Baby B based on positioning.
  • Vaginal delivery likelihood reduces with one being breech, highlighting the need for preparedness in an OR setting.

Understanding Placenta Previa and Placental Abruption

• Key differences between:
  • Placenta Previa:
  • Placenta blocks cervical opening causing painless bright red bleeding.
  • Risk factors include multiparity and prior surgeries on uterus.
  • Placental Abruption:
  • Sudden separation from uterine wall, typically causing pain and dark red bleeding.
  • Emergent condition demanding immediate action.
  • Associated with hypertension, abdominal trauma, and use of illicit drugs.

Assessing Conditions

• Placenta previa and its risk factors.
• Vigilance for complications in cases of placental abruption with careful monitoring of mother and fetus.

Oligohydramnios and Polyhydramnios

• Oligohydramnios:
  • Less than 500 mL of amniotic fluid.
  • Associated often with post-term pregnancies and can indicate fetal distress.
• Polyhydramnios:
  • Greater than 1000 mL of amniotic fluid.
  • Considerations include fetal anomalies and maternal conditions like uncontrolled diabetes.

Clinical Assessments and Interventions

• Throughout labor, careful assessments should be made regarding fetal positioning, amniotic fluid amounts, and maternal status.
• Identifying management practices for oligohydramnios or polyhydramnios.
  • Interventions may include amniotic infusions for oligohydramnios or careful management of delivery in polyhydramnios.

Summary

• Understand the implications of various fetal and maternal conditions during pregnancy.
• Importance of continual surveillance and addressing every concern as they arise is crucial to ensure the mother and baby's safety.
