Overview
Chorioamnionitis is an intra-amniotic infection typically caused by bacteria, leading to inflammation of the fetal membranes and potential neonatal complications if not promptly treated 1.Diagnosis
Clinical signs include fever, uterine tenderness, and foul-smelling amniotic fluid 1.
Laboratory criteria often involve elevated white blood cell count in amniotic fluid 1.
Microbiological confirmation through amniotic fluid culture is essential for identifying specific bacterial pathogens 1.Management
First-line treatment: Intramuscular or intravenous administration of a first-generation cephalosporin, such as cefazolin, as a single dose preoperatively 1.
Adjunctive measures: Broad-spectrum coverage with additional agents like azithromycin may be considered in specific cases, though less commonly practiced 1.Special Populations
Pregnancy: Focus on maternal and fetal safety; antibiotic choice should minimize risk to the neonate 1.
Neonates: Close monitoring for sepsis and respiratory distress post-delivery, especially in cases of prolonged rupture of membranes 1.Key Recommendations
Routine use of a single dose of a first-generation cephalosporin (e.g., cefazolin) for antibiotic prophylaxis in cesarean delivery to prevent postoperative infections, including those related to chorioamnionitis 1 (Evidence: Strong).
Preoperative administration of antibiotics is preferred over post-cord clamping to ensure coverage before potential exposure to pathogens 1 (Evidence: Strong).
Consider extended spectrum antibiotic regimens in specific clinical scenarios, though these are less frequently recommended 1 (Evidence: Moderate).References
