DESCRIPTION
This presentation highlights the etiology, clinical manifestations, pathogenesis, diagnostic criteria, and medical management of disseminated intravascular coagulation (DIC), while suggesting appropriate nursing diagnoses and patient teaching for the disorder.TRANSCRIPT

Disseminated Intravascular Coagulation (DIC) Alyssa Cardinal
-
Dont let the
name fool you.
The term disseminated intravascular coagulation can be misleading because it suggests the blood is clotting.
This is not necessarily the case.
-
DIC is a massive activation of the coagulation system leading to systemic clot formation and emboli.
Consumption of clotting factors faster than synthesis leads to systemic BLEEDING!
So, what is it?
-
Etiology DIC is:
not a disease
an abnormal response of the normal clotting cascade stimulated by a disease process or disorder
DIC can: occur as an acute,
subacute, or chronic condition
-
Clinical Manifestations Bleeding manifestations:
Pallor, petechiae, purpura, oozing blood, venipuncture site bleeding, hematomas, and occult
hemorrhage
Respiratory manifestations:
Tachypnea, hemoptysis, and orthopnea
Cardiovascular manifestations: Tachycardia, hypotension
GI manifestations: Upper and lower GI bleeding, abdominal distention,
and bloody stools
Urinary manifestations: Hematuria
Neurological manifestations Vision changes, dizziness, headache, changes in mental
status, and irritability
Musculoskeletal manifestations Bone and joint pain
-
Diagnostic Studies clotting breakdown of fibrin and fibrinogen fibrin split products (FSPs)
FSPs interfere with blood coagulation
D-dimer is a specific marker for the degree of fibrinolysis.
Fragmented erythrocytes (schistocytes) may be found on blood smears.
Tests that measure raw materials needed for coagulation (e.g., platelets, fibrinogen) are reduced, and values that measure times to clot (e.g., PT, PTT) are prolonged.
-
LABS
-
Collaborative Care Diagnose quickly
Stabilize if needed (O2, volume replacement)
Treat the underlying cause
Control the ongoing thrombosis and bleeding
Apply pressure to leaking IV/central line/arterial line sites
Administer PLATELETS to correct thrombocytopenia if Platelet count is < 20,000 or
-
Nursing Diagnoses Ineffective peripheral tissue perfusion related to
bleeding and sluggish or diminished blood flow secondary to thrombosis
Acute pain related to bleeding into tissues and diagnostic procedures
Decreased cardiac output related to fluid volume deficit
Anxiety related to fear of the unknown, disease process, diagnostic procedures, and therapy
