Here’s the **complete, structured, and exhaustive medical overview of *Antepartum Hemorrhage (APH)*** — formatted for clarity, clinical depth, and quick reference. --- ## 🩸 **ANTEPARTUM HEMORRHAGE (APH)** ### 🔹 Definition **Antepartum Hemorrhage (APH)** is **bleeding from or into the genital tract after 20 weeks of gestation and before the birth of the baby**, excluding bleeding due to labor or cervical causes. It is a major cause of **maternal morbidity, mortality, and perinatal loss**. --- ## 🧬 **Pathophysiology** Bleeding arises due to **disruption of placental attachment** or **vascular lesions** in the uterus or genital tract: 1. **Placenta previa:** Placenta implanted low, covering or near cervix → bleeding when lower uterine segment stretches. 2. **Placental abruption:** Premature separation of normally implanted placenta due to vascular rupture. 3. **Vasa previa:** Fetal vessels traverse membranes over cervix → rupture → fetal blood loss. 4. **Local genital causes:** Cervical erosion, polyps, carcinoma, varices. --- ## ⚠️ **Etiology / Causes** ### 1. **Placental causes** * **Placenta previa** (20–30%) * **Placental abruption** (30–40%) * **Vasa previa** ### 2. **Local causes** * Cervical polyp * Cervicitis * Carcinoma cervix * Vaginal trauma or varicosities ### 3. **Unclassified / Idiopathic** --- ## 🧠 **Risk Factors** | Category | Risk Factors | | ----------------------- | --------------------------------------------------------------------------------------------------- | | **Placenta previa** | Previous C-section, multiparity, advanced maternal age, multiple pregnancy, smoking, IVF conception | | **Placental abruption** | Hypertension, preeclampsia, trauma, smoking, cocaine use, folate deficiency, previous abruption | | **Vasa previa** | Low-lying placenta with velamentous cord insertion, multiple pregnancy | --- ## 🩺 **Clinical Features** ### 🔸 *Placenta Previa* * **Painless, bright red bleeding** * Often **recurrent** * **No uterine tenderness** * **Fetal parts easily felt** * **Malpresentation common** * **Uterus soft and non-tender** * **Fetal heart present (usually)** ### 🔸 *Placental Abruption* * **Painful, dark bleeding** * **Tense, tender uterus** * **Uterine contractions + board-like abdomen** * **Fetal distress or absent heart sounds** * **Maternal shock disproportionate to visible blood loss** * **May have Couvelaire uterus (blood infiltrating myometrium)** ### 🔸 *Vasa Previa* * **Bleeding at rupture of membranes** * **Fetal distress/bradycardia immediately after** * **Maternal condition stable but fetus compromised** --- ## 🧪 **Investigations** ### 🩸 *Initial assessment* * Vitals, shock evaluation * CBC (Hb, Hct, Platelets) * Blood grouping and cross-match * Coagulation profile (PT, aPTT, fibrinogen) * Renal and liver function tests ### 🧭 *Specific* * **Ultrasound (USG):** To locate placenta → *transvaginal USG most accurate* * **Kleihauer–Betke test:** For fetomaternal hemorrhage * **CTG / NST:** For fetal well-being * **Speculum exam:** Only after placenta previa ruled out by USG * **Avoid digital vaginal exam** until placenta previa excluded!
