Sent to Histopathology: Placenta samples are sent only if there is an interest in the results, rather than for routine practice.
Follow-Up: It's essential to include the doctor in charge of the shift, ensuring they follow up on the results.
Link to Appointments: Placenta examinations are often tied to a postpartum appointment 6 weeks after birth, allowing discussion of complications.
Chorioamnionitis Overview
Definition: Chorioamnionitis is inflammation of the fetal membranes, often caused by ascending bacterial infections from the lower genital tract, and can have significant impacts on both maternal and neonatal health.
Common Terminology: Also known as intra-amniotic infection (IAI), primarily occurs before or during labor.
Clinical Significance: Associated with adverse outcomes for both mother and baby, necessitating knowledge of pathophysiology, risk factors, clinical signs, etc.
Historical Context: Previously, low-risk women with a ruptured membrane were given three days to labor; however, this practice has changed due to evidence showing increased incidence of chorioamnionitis.
Infection Pathways and Management
Infection Origins: Bacterial infections often originate from the lower genital tract; the most common pathogens include:
Ureaplasma
Mycoplasma
E. coli
Group B Streptococcus (GBS)
Prognostic Indicators: Understanding whether the bacteria originated from maternal or fetal sides is key for treatment decisions in chorioamnionitis.
Handling of Placenta: Important to handle the placenta minimally to prevent contamination; use swabs effectively, labeling them as maternal, fetal, or intramembrane swabs.
Clinical Presentation and Symptoms
Symptoms to Monitor:
Maternal fever (>38°C)
Maternal tachycardia (>100 bpm)
Foul-smelling amniotic fluid
Uterine tenderness
Maternal leukocytosis (elevated white blood cell count)
Fetal Signs: Fetal tachycardia and decreased fetal movements may also present.
Diagnostic Procedures
Blood Cultures: Important to perform before starting antibiotics. Recognize potential for contamination and ensure proper labeling for effective treatment.
PROM Assessment:
Varies by facility; methods can include fluid testing kits or simple visual assessments.
Laboratory Tests:
CRP (C-reactive protein) to assess inflammation levels and infection response.
Elevated levels indicate the presence of infection, especially in cases of bacterial vs viral origins.
Chorioamnionitis Risks and Cause Analysis
Risk Factors:
Pregnant state (immunocompromised)
Premature rupture of membranes (PROM)
Prolonged labor
Multiple vaginal examinations
History of urinary tract infections (UTIs) or sexually transmitted infections (STIs)
Young maternal age and low socioeconomic status
Myth vs Fact: The increased infection rate among younger mothers is more correlated with individual and systemic disadvantages rather than biological factors.
Management Strategies
Antibiotic Treatment:
Implement early and broad-spectrum antibiotics such as Ampicillin and Gentamicin, or alternatives for allergic patients (Clindamycin).
Postpartum Protocols: Continue antibiotics for 24-48 hours post-birth in cases of chorioamnionitis to prevent secondary infections.
Prompt Birth Necessity: Emphasizes the importance of delivering the baby quickly, particularly if there is concern regarding neonatal health in an infected environment.
Ethical Considerations and Maternal Health
Mother's Postpartum Risks: Chorioamnionitis poses a risk not only to the newborn but also to the mother, necessitating ongoing health monitoring after delivery due to potential infections.
Relational Midwifery: Establishing a strong relationship with expectant mothers can lead to greater transparency about personal health issues that may pose risks during pregnancy.
Conclusion and Open Discussion
Role of Proper Education: Encouragement for mothers to discuss any health concerns openly with healthcare providers to manage risks effectively.
Call for Future Research: Highlights the importance of ongoing studies to track long-term outcomes for both mother and child post-exposure to infections and complications like chorioamnionitis.
