O46.021
Antepartum hemorrhage with disseminated intravascular coagulation, first trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Antepartum hemorrhage with disseminated intravascular coagulation (DIC) during the first trimester is a serious pregnancy complication that requires prompt medical attention. This condition involves bleeding during pregnancy combined with a blood clotting disorder known as DIC, which affects the body's ability to control bleeding and clotting properly. Recognizing the signs and understanding the causes, symptoms, diagnosis, and treatment options can help expectant mothers and their families be more informed and prepared.
Causes & Symptoms
Clinical Causes: Placental abruption or premature separation of the placenta from the uterine wall Placenta previa where the placenta covers the cervical opening Severe infections during pregnancy such as placental abruption due to infection Pre-existing clotting or bleeding disorders Hypertensive disorders like preeclampsia Multiple pregnancies or molar pregnancy Trauma or injury to the abdomen during pregnancy Use of certain medications or substances that affect blood clotting
Key Symptoms: Vaginal bleeding or spotting in the first trimester Lower abdominal pain or tenderness Signs of shock such as dizziness, fainting, or cold extremities Rapid heartbeat or breathing Bleeding that worsens or does not stop Unusual bruising or petechiae (small red or purple spots on the skin) Signs of coagulopathy like bleeding from gums or nose
Diagnostic & Treatment
Diagnosis Path: Pelvic ultrasound to evaluate placental position and fetal well-being Blood tests to assess blood counts, clotting factors, and DIC markers such as D-dimer, fibrinogen levels, and platelet count Blood typing and crossmatching in case blood transfusion becomes necessary Monitoring fetal heart rate and overall fetal health through electronic fetal monitoring
Treatment Protocols: Immediate hospital admission for close monitoring Blood transfusions to replace lost blood and replace clotting factors Intravenous fluids to maintain hydration and blood pressure Medications to control bleeding or promote clotting as needed Delivery of the fetus if the pregnancy is viable and continuing poses risks to mother or baby Treating underlying causes such as infections or hypertensive disorders Multidisciplinary care involving obstetricians, hematologists, and neonatologists
