What are treatment options for DVT?
DVT treatment options include:Blood thinners. DVT is most commonly treated with anticoagulants, also called blood thinners. ... Clot busters. Also called thrombolytics, these drugs might be prescribed if you have a more serious type of DVT or PE , or if other medications aren't working. ... Filters. ... Compression stockings.
How long after heparin bolus should aPTT be checked?
Heparin prevents the reaccumulation of a clot after spontaneous fibrinolysis. When UFH is used, the aPTT should not be checked until 6 hours after the initial heparin bolus, because an extremely high or low value during this time should not provoke any action. Warfarin (Coumadin, Jantoven) View full drug information.
What is rivaroxaban used for?
Rivaroxaban is indicated for treatment of PE and for prevention of re currence (following initial 6 months of treatment). Additionally, it is indicated for a variety of treatment and prophylaxis VTE indications, including the following: --Risk reduction of stroke and systemic embolism in nonvalvular atrial fibrillation.
What is Alteplase used for?
Alteplase is most often used to treat patients with pulmonary embolism in the ED. It is usually given as a front-loaded infusion over 90-120 minutes.
What is Lovenox heparin?
Enoxaparin (Lovenox) View full drug information. Exonaparin was the first low-molecular-weight heparin (LMWH) released in the United States. It was approved by the FDA for both treatment and prophylaxis of DVT and PE. Enoxaparin enhances the inhibition of factor Xa and thrombin by increasing antithrombin III activity.
What is Warfarin used for?
It is used for the prophylaxis and treatment of venous thrombosis, pulmonary embolism, and thromboembolic disorders.
Does enoxaparin increase thrombin?
Enoxaparin enhances the inhibition of factor Xa and thrombin by increasing antithrombin III activity. In addition, it preferentially increases the inhibition of factor Xa. LMWH has been used widely in pregnancy, although clinical trials are not yet available to demonstrate that it is as safe as unfractionated heparin.
Is weight adjusted heparin appropriate for prophylaxis?
The weight-adjusted heparin dosing regimens that are appropriate for prophylaxis and treatment of coronary artery thrombosis are too low to be used unmodified in the treatment of active DVT and PE. Coronary artery thrombosis does not result from hypercoagulability but rather from platelet adhesion to ruptured plaque.
What is the risk of pulmonary embolism?
Pulmonary embolism, or PE, is the obstruction of one or more branches of the pulmonary artery. It can strike abruptly and cause sudden death. The number one risk factor for PE is deep vein thrombosis, or DVT. The risk for DVT and PE is high during periods of prolonged immobility after surgery. With DVT, a blood clot, air bubble, or fat particle ...
What is the treatment for respiratory distress after PE?
Chest X-ray may also be used to rule out other causes of respiratory distress. After PE diagnosis, the patient receives IV anticoagulants such as heparin. This prevents new clots from forming. To reduce the clot size, the patient may also receive a thrombolytic agent such as Alteplase.
What is the diagnostic test for PE?
Diagnostic testing for PE includes imaging and laboratory studies. Diagnostic studies include an ECG, a chest CT with contrast (not without), a V/Q scan, and pulmonary angiography. Laboratory studies include arterial blood gas analysis (not venous) and a plasma D-dimer level. Drug Therapy to Treat PE. Heparin drip.

BNP, which is B-type natriuretic peptide, is tested to rule out heart failure. The best test for PE is the computed tomography scan with contrast. If this is unavailable, a VQ, or ventilation-perfusion scan, shows areas of the lung that are not receiving enough oxygenated blood.
How to prevent recurrence of PE?
Patient teaching to prevent the recurrence of PE includes implementation of an exercise regimen to include aerobic exercise. The exercise will strengthen the patient's heart and cardiovascular system, improve venous return to the heart, and assist with weight loss.
Where does DVT go?
With DVT, a blood clot, air bubble, or fat particle breaks free from the lower extremity veins, becoming an embolus. It travels to the lungs, where it can obstruct a small artery or arterial branch. The pulmonary artery is a major highway for oxygen exchange.

The tracer maps blood flow (perfusion) and compares it with the airflow to your lungs (ventilation) and can be used to determine whether blood clots are causing symptoms of pulmonary hypertension.
How accurate is a pulmonary embolism test?
This test provides a clear picture of the blood flow in the arteries of your lungs. It's the most accurate way to diagnose pulmonary embolism, but because it requires a high degree of skill to administer and has potentially serious risks, it's usually performed when other tests fail to provide a definitive diagnosis.
Why is it important to keep on blood thinners?
Because you may be at risk of another deep vein thrombosis or pulmonary embolism, it's important to continue treatment, such as remaining on blood thinners, and be monitored as often as suggested by your doctor. Also, keep regular doctor visits to prevent or treat complications.
