N85.3

Clinical Causes: Retained products of conception, such as placental tissue or clots Infection of the uterus (endometritis) Uterine atony, where the uterus fails to contract efficiently Injury or trauma during delivery Previous uterine surgery or procedures Hormonal imbalances affecting uterine contractions

Key Symptoms: Prolonged bleeding or lochia that lasts longer than expected Persistent or foul-smelling vaginal discharge Lower abdominal pain or tenderness Enlarged or tender uterus upon clinical examination Signs of infection, such as fever or chills Feeling of pelvic pressure or heaviness

Diagnosis Path: Diagnosis typically involves a combination of medical history, physical examination, and diagnostic tests. A healthcare provider will examine the uterus to assess its size and position. Imaging techniques such as ultrasound are used to visualize retained tissue or other abnormalities. Blood tests may be performed to check for signs of infection or anemia. Monitoring symptoms and uterine size over time helps in confirming the diagnosis of subinvolution.

Treatment Protocols: Managing subinvolution involves addressing the underlying cause and preventing complications. Common approaches include: - Manual removal or curettage of retained products if identified - Administration of uterotonics, such as oxytocin, to stimulate uterine contractions - Antibiotics if an infection is present - Supportive care, including blood transfusions in severe bleeding cases - Close follow-up to ensure complete involution and recovery In some cases, intervention may be necessary to resolve ongoing bleeding or other complications, always under the guidance of a healthcare professional.
