Exam 3 - DIC Flashcards
1
Q
balance between two opposing systems
A
normal clotting of disseminated intravascular coagulation (DIC)
2
Q
involved with stopping blood flow from injured vessels
•complex cascade of clotting factors
•formation of insoluble fibrin that “plugs” vessel
A
hemostatic system
1st of normal clotting DIC
3
Q
process in which fibrin is broken down in fibrin degradation products(FDP) and normal circulation restored
-Breaks down fibrin so it doesn’t stick together
A
fibrinolytic system
2nd of normal clotting DIC
4
Q
- Over-consumption of clotting factors causes widespread external and/or internal bleeding
- Life-threatening condition
A
DIC
5
Q
•Spontaneous bleeding from gums or nose •Petechiae from minor bumps, BP cuff (capillaries are broken - see "pinpricks" •Excessive bleeding from IV, injections, catheter sites •Tachycardia •Diaphoresis
A
DIC signs and symptoms
6
Q
Labs •decreased platelets, fibrinogen, prothrombin •prolonged PT--prothrombin time •bleeding time normal •coagulation time--no clotting •PTT increased--partial thromboplastin time
A
DIC signs and symptoms
7
Q
• Correction of underlying cause - removal of dead fetus - treatment of pre-eclampsia, eclampsia - treatment of infection - removal of placental abruption • Packed RBCs • Fresh frozen plasma and plasma concentrates
A
DIC medical management
8

- Monitor urinary output (>30 ml/hr)
- Administer O2 at 10-12 L/min
- Education and support
