[Chorioamnionitis in the delivery room]

Area of Science:

• Obstetrics and Gynecology
• Infectious Diseases
• Perinatal Medicine

Context:

• Chorioamnionitis (CA) affects 10-40% of maternal peripartum fever cases and 50% of preterm labor cases.
• Diagnosis relies on maternal fever plus at least two other clinical signs, though histological confirmation is not always definitive.
• Risk factors include nulliparity, prolonged labor, genital tract pathogens, and frequent vaginal exams.

Purpose:

• To define chorioamnionitis, outline diagnostic criteria, identify risk factors, and discuss management and complications.
• To emphasize the importance of early antibiotic intervention in managing chorioamnionitis.
• To highlight potential maternal and neonatal morbidities associated with chorioamnionitis.

Summary:

• Chorioamnionitis is an infection of the fetal membranes and amniotic fluid, often diagnosed clinically.
• Risk factors and diagnostic criteria are established, but histological confirmation can be variable.
• Early broad-spectrum antibiotic therapy (e.g., ampicillin and gentamicin) is the standard treatment, reducing maternal and neonatal morbidity.

Impact:

• Early antibiotic administration significantly reduces maternal and neonatal morbidity associated with chorioamnionitis.
• Prompt management can prevent severe complications such as sepsis, septic shock, and neonatal distress.
• Continuous fetal monitoring and timely Cesarean section are vital in managing fetal distress in suspected chorioamnionitis cases.
