various agents: thrombolytics clot busters (used in ER if some one is having a stroke or heart attack
various agents: hemostatic agents mainly used in OR if the pt. starts bleeding too much (they promote blood clotting)
Heparin monitored by activated partial thromboplastin times (aPTTs) **maintain at 1.5-2.5 times the baseline value **normal control 25-35 seconds **therapeutic values 45-70 seconds
what is the antidote for heparin? protamine sulfate
low molecular weight heparins enoxaparin (lovenox) and dalteparin (fragmin) **do not require frequent lab monitoring **give it in the stomach (pinch skin, do not massage, or aspirate)
warfarin (coumadin) -given orally only -monitored by prothrombin time (PT) or INR **INR therapeutic 2.0-3.0 **PT control 12 seconds, therapeutic value 1.5 times control **monitor labs daily until stable dose reached
what is the antidote for coumadin? vitamin K
antiplatelet agents aspirin, dipyridamole (persantine), clopidogrel (plavix)
if you are going to have surgery when should you stop antiplatelet agents? stop atleast 7 days prior to planned surgery
antifibrinolytic agents prevent the lysis of fibrin **promote clot formation **used for prevention and treatment of excessive bleeding resulting from surgical complications
antifibrinolytic agents -aminocaproic acid (amicar) --> most commonly used in surgery -desmopressin (DDAVP) --> similar to ADH, used in treatment of diabetes insipidus
thrombolytic agents break down or lyse clots **streptokinase & urokinase (older agents)--> these can give allergic reactions **TPA (tissue plasminogen activator) **anisoylated plasminogen-streptokinase activator complex (APSAC) **alteplase, reteplase, tenecteplase
what is the antidote for thrombolytic agents aminocaproic acid (amicar)

a pt has received a double dose of heparin in surgery and is bleeding through the incision site. the nurse should prepare to take what action at this time? give IV protamine sulfate as an antidote
a pt is starting warfarin (coumadin) therapy as part of the treatment for A fib. The nurse will follow which principles of warfarin therapy? -administer the oral dose at the same time everyday -assess carefully for excessive bruising or unusual bleeding -monitor labs for a target INR of 2.0-3.0
