    Warfarin is safe and effective for preventing blood clots after hip surgery when started post-operation. It causes fewer bleeding issues compared to dextran, which is also effective but increases bleeding risks.

    Area of Science:

    • Orthopedic surgery
    • Pharmacology
    • Thromboembolic disease prevention

    Background:

    • Thromboembolic complications are a significant risk after total hip replacements.
    • Effective anticoagulation is crucial for patient safety post-surgery.

    Purpose of the Study:

    • To evaluate the safety and efficacy of warfarin versus dextran in preventing thromboembolic complications after elective total hip operations.
    • To compare bleeding complications associated with each agent.

    Main Methods:

    • Warfarin administration initiated on the first postoperative day.
    • Dosage adjusted to maintain prothrombin time between 1.5 and 2.0 times the control.
    • Dextran administration evaluated, including intraoperative use.

    Main Results:

    • Warfarin demonstrated safety and efficacy in preventing thromboembolic complications.
    • Warfarin use was associated with minimal bleeding complications when administered correctly.
    • Dextran was effective but associated with increased bleeding problems, particularly with intraoperative administration.

    Conclusions:

    • Warfarin is a safe and effective option for preventing thromboembolic complications following total hip surgery.
    • Optimal warfarin dosing and timing (postoperative day 1) minimize bleeding risks.
    • Dextran poses a higher bleeding risk, especially when given during surgery.
