    Study Notes

    Miscarriage/Spontaneous Abortion

    • Defined as pregnancy loss before the fetus reaches viability, typically before the 20th week (some definitions extend to 24 weeks).
    • Risk factors include:
      • Maternal age, with increased risk as age rises.
      • History of prior pregnancy loss.
      • Pre-existing medical conditions, such as infections, stress, and chronic disorders.
      • Medications like NSAIDs and psychiatric drugs, along with caffeine and alcohol exposure.
      • Lifestyle factors, including smoking and environmental toxins.
    • Common causes are multifactorial including trauma, chromosomal abnormalities, and maternal anatomical anomalies.
    • Clinical presentation varies:
      • Uncomplicated cases present with vaginal bleeding (light to heavy) and cramping pain.
      • Complicated cases may present with heavy bleeding accompanied by signs of hypovolemic shock or infection (pelvic pain, tenderness, fever, tachycardia).

    Prehospital Management for Miscarriage

    • Important to gather patient history, vital signs, and perform a physical exam.
    • Provide emotional support and sanitary pads for patient comfort.
    • Most patients are stable and should be transported to a hospital for further evaluation.
    • Symptomatic treatment may include supplemental oxygen and IV saline (500 ml) if shock is present.

    Antepartum Hemorrhage

    • Defined as bleeding from the genital tract in pregnancy at or after 20 weeks of gestation (some sources specify 24 weeks).
    • Common causes include:
      • Placenta previa
      • Placental abruption
      • Vasa previa
      • Uterine rupture

    Placenta Previa

    • Characterized by placental tissue covering the internal cervical os.
    • Potential complications:
      • Antepartum hemorrhage
      • Preterm labor or birth
      • Intrapartum and postpartum hemorrhage
    • Pathogenesis is largely unknown.
    • Risk factors include:
      • Previous placenta previa or cesarean births.
      • Multiple gestations and increased maternal age.
      • History of uterine surgical procedures, infertility treatments, maternal smoking, endometriosis, and prior abortions.
    • Clinical presentation typically involves painless vaginal bleeding (90% of cases) and is often detected via ultrasound.

    Placental Abruption

    • Defined as the premature detachment of the placenta from the uterine wall after 20 weeks gestation.
    • It can lead to significant maternal and neonatal morbidity and mortality.
    • Blood can accumulate behind the placenta or be lost through the cervix.
    • Risk factors include:
      • Trauma, especially abdominal.
      • Substance use (cocaine, smoking, other drugs).
      • Conditions like polyhydramnios, chronic hypertension, pre-eclampsia, and eclampsia.
      • Increased maternal age and a history of previous abruption.
    • Types of placental abruption include concealed (no external bleeding) and revealed (external bleeding).
