Final answer:
Unfractionated Heparin (UFH) and Low Molecular Weight Heparin (LMWH) are both anticoagulants used after surgeries. UFH is preferred when immediate effects and monitoring are necessary, while LMWH is used for extended prophylaxis in the post-operative period.
Step-by-step explanation:
Unfractionated Heparin (UFH) and Low Molecular Weight Heparin (LMWH) are both anticoagulants used after surgical procedures, but their use depends on specific factors.
UFH is commonly used during surgeries and is administered intravenously. It has a short half-life and can be quickly reversed if necessary. UFH is usually preferred when there is a need for immediate anticoagulation and monitoring the effects is important.
On the other hand, LMWH is typically used in post-operative periods for extended prophylaxis against venous thromboembolism. LMWH has a longer half-life and can be administered subcutaneously. It provides more stable anticoagulation and does not require continuous monitoring.
