O41.122
Chorioamnionitis, second trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Chorioamnionitis, also known as intra-amniotic infection, is an inflammation of the membranes surrounding the fetus, called the chorion and amnion. When it occurs during the second trimester of pregnancy, it can pose significant risks to both the mother and the developing baby. Understanding this condition helps expectant mothers and their healthcare providers manage it effectively, ensuring the best possible outcomes for both.
Causes & Symptoms
Clinical Causes: Bacterial infection from the vaginal flora ascending into the amniotic cavity. Prolonged rupture of membranes, increasing the risk of bacteria entering the uterus. Preterm labor, which can alter the normal immune defenses of the uterus. Invasive procedures during pregnancy, such as amniocentesis or cervical cerclage. Multiple vaginal examinations, which may introduce bacteria.
Key Symptoms: fever or chills uterine tenderness or warmth foul-smelling vaginal discharge abnormal or increased uterine tenderness matte or dull uterine activity abdominal pain or discomfort possible signs of preterm labor, such as regular contractions fetal tachycardia detected through fetal monitoring
Diagnostic & Treatment
Diagnosis Path: Diagnosis of chorioamnionitis typically involves a combination of clinical assessment and laboratory tests. Healthcare providers may examine for signs such as maternal fever, uterine tenderness, and foul-smelling discharge. Laboratory tests include high white blood cell count, amniotic fluid analysis showing infection, and cultures to identify specific bacteria. Fetal monitoring is also essential to assess the baby's response to infection.
Treatment Protocols: Managing chorioamnionitis usually involves prompt administration of antibiotics to control infection. Depending on the stage of pregnancy and the health of the mother and baby, healthcare providers may opt to induce labor to reduce further risks. Close monitoring of both mother and fetus is essential throughout treatment. In some cases, corticosteroids might be administered to accelerate fetal lung maturity if preterm delivery is anticipated.
