O45.91
Premature separation of placenta, unspecified, first trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Premature separation of the placenta, also known as placental abruption, is a condition that occurs when the placenta detaches from the wall of the uterus before delivery. Specifically, the ICD-10 code O45.91 refers to cases where this separation happens during the first trimester of pregnancy without specifying further details. This condition can pose risks to both the mother and the developing fetus, making early recognition and management crucial for health and safety.
Causes & Symptoms
Clinical Causes: High blood pressure or hypertension during pregnancy Trauma or abdominal injury History of placental abruption in previous pregnancies Smoking or substance abuse Use of certain medications affecting blood clotting Multiple pregnancies (twins or more) Rapid uterine growth or abnormalities Infections or inflammatory conditions in the uterus Advanced maternal age
Key Symptoms: Vaginal bleeding, which may be mild or heavy Abdominal or uterine pain and tenderness Contractions or signs of preterm labor Back pain or abdominal discomfort Rapid uterine contractions or increased tone Signs of fetal distress, such as decreased fetal movement
Diagnostic & Treatment
Diagnosis Path: A physical examination to assess uterine tenderness and tone Ultrasound imaging to visualize placental location and possible detachment Monitoring fetal heart rate patterns for signs of distress Blood tests to check for anemia or signs of bleeding Assessment of maternal vital signs and overall stability
Treatment Protocols: Immediate hospitalization for close monitoring Rest and activity restriction to reduce uterine stress Blood transfusions if significant bleeding has occurred Medications to manage pain and prevent contractions Steroid injections to accelerate fetal lung maturity if early delivery might be necessary Delivery, often by cesarean section, if the health of mother or fetus is at risk Monitoring for signs of ongoing bleeding or fetal distress
