Study Notes
Fetal Indirect Harm and Maternal Diseases
- Indirect harm to the fetus occurs due to placental injury from maternal diseases, assessable through sonography.
- Key areas of assessment include placental maturation, amniotic fluid, intrauterine growth restriction (IUGR), and maternal disease.
- Infections post-implantation are significant contributors to adverse fetal effects, spreading through the placenta into fetal circulation.
Third Trimester Infections
- Fetal infections primarily occur in the third trimester, linked with severe outcomes such as:
- Hydrocephalus
- Seizures
- Cerebral palsy
- Anemia
- Jaundice
- Hepatosplenomegaly
- Erythroblastosis
- Intracranial calcifications
Cytomegalovirus
- Cytomegalovirus is the most common cause of intrauterine infections, associated with:
- IUGR
- Microcephaly
- Cranial calcifications
- Blindness
- Seizures
- Jaundice
- Thrombocytopenia
- Hepatosplenomegaly
Diabetes Mellitus
- Diabetes is the most prevalent maternal disorder, categorized into:
- Type I
- Type II
- Gestational
- Associated complications include macrosomia, increased risk for birth trauma, and shoulder dystocia.
Pregnancy-Induced Hypertension (PIH)
- Resolves after delivery; features include:
- Hypertension, often linked to HELLP syndrome, which comprises hemolysis, elevated liver enzymes, and low platelets.
- Symptoms like maternal edema, abdominal pain, and CNS irritability may present during preeclampsia.
Eclampsia
- Eclampsia includes all preeclampsia symptoms plus convulsions and coma.
- Associated risks include low birth weight, fetal distress, and placental abruption.
Postpartum Uterine Changes
- Postpartum appearance shows an open cervical os, homogeneous myometrium, enlarged myometrial vessels, and thick endometrium.
- Normal fluid levels range from 1.2 to 1.4 cm in thickness.
Postpartum Hemorrhage
- Defined as blood loss exceeding 500 ml in vaginal deliveries and 1000 ml in cesarean deliveries.
- Most common cause is abnormal placental attachment, classified into:
- Placenta accreta
- Placenta increta
- Placenta percreta
- Uterine atony is the leading cause; risk factors include multifetal pregnancy, macrosomia, prolonged labor, and rapid labor.
Sonographic Indicators of Hemorrhage
- Loss of hypoechoic rim of myometrial tissue and reduction in hyperechoic serosa to bladder interface indicates potential complications.
- Factors like prior cesarean section, advanced maternal age, and endometrial defects increase hemorrhage risk.
Puerperal Infection
- Symptoms arise within 24 hours post-delivery, including fever, chills, malaise, and a large tender uterus.
- Sonographic findings may show fluid in the cavity, thickened endometrium, or gas presence.
Types of Infection
- Includes kidney, breast, endometritis, and thrombophlebitis.
- Endometritis arises from normal flora migration and conditions such as PROM and RPOC.
Postpartum Ovarian Vein Thrombophlebitis (PVOT)
- Involves clot formation within the ovarian vein, particularly after cesarean deliveries.
- Symptoms align with Virchow's triad: hypercoagulability, venous stasis, and venous wall damage.
Cesarean Section Complications
- Common complications include hematomas and infections.
Key Tidbits
- Turning the patient on the left side mitigates IVC compression, preventing supine hypotensive syndrome.
- Fetal heart rate is detectable at the umbilicus by around 20 weeks of gestation.
- Measurements related to crown-rump length (CRL) offer days of gestation calculations.
Genetic Concepts
- Syndromes involve multiple anomalies from a single pathology (trio of trisomy).
- Associations and sequences describe patterns of multiple anomalies due to unrelated causes or sequential developmental issues.
- Anomalies classification includes malformations, deformations, disruptions, and dysplasias, each with distinct characteristics.
General Genetics
- Genes comprise DNA; chromosomes house these genes, and cell nuclei contain chromosomes.
