O45.90
Premature separation of placenta, unspecified, unspecified trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Premature separation of the placenta, also known as abruptio placentae, is a serious pregnancy complication where the placental tissue detaches from the uterus wall prematurely, before the baby is born. This condition can pose significant risks to both the mother and the baby, requiring prompt medical attention. The ICD-10 code O45.90 covers cases where this separation occurs without specifying the trimester or exact cause, emphasizing its unpredictable nature during pregnancy.
Causes & Symptoms
Clinical Causes: High blood pressure during pregnancy (pre-eclampsia or eclampsia) Trauma or injury to the abdomen, such as a fall or accident Previous history of placental abruption Multiple pregnancies (twins or more) Advanced maternal age Cocaine or drug use during pregnancy Smoking during pregnancy Placental abnormalities or uterine abnormalities Infections that affect the pregnancy Rapid uterine growth or overstretching
Key Symptoms: Sudden, severe abdominal pain that may be concentrated on one side Vaginal bleeding, which can be light or heavy Irritated or tense uterus (uterine hypertonus) Back pain or abdominal tenderness Signs of fetal distress, such as a decelerating heartbeat Reduction in fetal movements Low blood pressure in severe cases Signs of shock, including dizziness or fainting
Diagnostic & Treatment
Diagnosis Path: Diagnosing placental abruption involves a combination of maternal assessment and diagnostic tests. Healthcare providers typically perform a physical examination to check for uterine tenderness and tone. An ultrasound scan is commonly used to visualize the placenta and estimate bleeding, although it may not always detect an abruption. Monitoring fetal heart rate can reveal distress suggestive of placental separation. In some cases, laboratory tests such as blood counts and clotting profiles are conducted to assess maternal health and blood loss.
Treatment Protocols: Treatment for placental abruption depends on the severity of the separation, gestational age, and the condition of both mother and baby. Hospitalization is often necessary for close monitoring. Mild cases might be managed conservatively if the pregnancy is not yet full term and both mother and fetus are stable, with bed rest and frequent checks. Severe cases with significant bleeding or fetal distress often require immediate delivery, sometimes via emergency cesarean section, to ensure safety. Blood transfusions or other supportive care may be needed to address maternal blood loss, and the care team will determine the timing and method of delivery based on the situation.
