HIGH-YIELD TOPIC: DISSEMINATED INTRAVASCULAR COAGULATION (DIC) 🩸
Highly important for Critical Care nursing sections. This is a complex "secondary" disorder.
📌 WHAT IS DIC?
A life-threatening condition where the body's clotting mechanism breaks down.
👉 Paradox: Massive clotting occurs first, followed by massive bleeding.
👉 It is NOT a primary disease: It is always a complication of another condition (Sepsis, Trauma, Abruptio Placentae).
📌 PATHOPHYSIOLOGY
Trigger (Sepsis/Trauma) →
Excessive Thrombin generation →
Widespread Micro-clots in capillaries →
Depletion of Clotting Factors & Platelets →
UNCONTROLLED BLEEDING.
📍 Key point: Organ failure happens because micro-clots block blood flow to kidneys, lungs, and brain.
📌 CAUSES (THE "TRIGGERS")
🔹 Sepsis: Most common cause (especially Gram-negative).
🔹 Obstetric Complications: Abruptio Placentae, Amniotic fluid embolism.
🔹 Major Trauma/Burns.
🔹 Cancer: Acute Leukemia.
🔹 Incompatible Blood Transfusion.
📌 CLINICAL FEATURES (THE BLEEDING SIGNS)
1️⃣ Petechiae & Ecchymosis (Small red spots/bruises).
2️⃣ Oozing from IV sites, incision sites, or mucous membranes.
3️⃣ Hematuria (Blood in urine).
4️⃣ Hematemesis (Blood in vomit).
5️⃣ Internal Bleeding Signs: Hypotension, Tachycardia, Decreased LOC.
📌 DIAGNOSTIC LABS (EXAM FAVORITE)
🔴 D-Dimer: ELEVATED (Most specific indicator).
🔴 Platelet Count: DECREASED.
🔴 Fibrinogen Level: DECREASED.
🔴 PT, PTT, and INR: PROLONGED (Increased time).
📌 MANAGEMENT & NURSING PRIORITIES
1️⃣ Treat the Underlying Cause: (e.g., Give antibiotics for sepsis).
2️⃣ Blood Products: Administer Fresh Frozen Plasma (FFP) and Platelets.
3️⃣ Heparin Therapy: (Controversial but used in early stages to stop micro-clotting).
4️⃣ Bleeding Precautions: No IM injections, use soft toothbrushes, use electric razors, gentle suctioning.
📌 NURSING ALERT: ORGAN PERFUSION
✔️ Monitor Urine Output (Check for Acute Kidney Injury).
✔️ Monitor Neurological Status (Check for Intracranial Bleed).
✔️ Monitor Oxygenation (Check for Lung injury/ARDS).
📌 EXAM QUICK POINTS
✔️ Best Lab Marker → Elevated D-Dimer.
✔️ Primary Nursing Goal → Early identification of bleeding & fluid volume maintenance.
✔️ Common Trigger → Septic Shock.
✔️ Platelets & Fibrinogen → Both are LOW in DIC.
✔️ Priority Action → Assess for "oozing" from previous puncture sites.
