What is the recommended approach for administering heparin for DVT treatment?

The recommended approach for administering heparin in the treatment of deep vein thrombosis (DVT) is a weight-based bolus followed by a weight-based continuous infusion. This method is preferred because it allows for immediate anticoagulation with the bolus, effectively reducing the risk of clot propagation, and the continuous infusion maintains therapeutic anticoagulation levels over time.

Weight-based dosing is crucial since it adjusts the heparin quantity according to the patient’s weight, ensuring that each individual receives the appropriate amount of medication to achieve the desired anticoagulant effect without increasing the risk of bleeding. Additionally, monitoring heparin levels through activated partial thromboplastin time (aPTT) or anti-Xa levels is important to ensure the dosage is adequate and safe.

Continuous infusion allows for more stable therapeutic levels of heparin compared to intermittent dosing, further ensuring effective prevention of clot formation while minimizing side effects. This approach has been established as the most effective method in current clinical guidelines for managing DVT.

In contrast, the administration of aspirin does not provide adequate anticoagulation for DVT treatment, as it primarily addresses platelet aggregation rather than affecting coagulation pathways. Also, using heparin administration based on INR values is not appropriate, as INR
