Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Fixed Dose 4FPCC | Incorporating a fixed dose of 1500 IU.~If the patient receiving the 1500 IU fixed dose remains in a bleeding state and the INR remains above goal, an additional 500 IU may be administered at the physician's discretion to minimize bleeding and attempt to achieve hemostasis.~4-factor prothrombin complex concentrate (4FPCC): 4-factor prothrombin complex concentrate (4FPCC) contains all of the vitamin K-dependent clotting factors inhibited by warfarin, making it desirable for use in warfarin reversal for emergent bleeds. Multiple guidelines currently recommend 4FPCC for warfarin reversal in vitamin K-dependent major bleeding or intracranial hemorrhage. 4FPCC has a fast onset of action and has demonstrated significant reversal of INR within 10 minutes. Its duration of action is up to 8 hours, and for this reason it should be given concurrently with vitamin K. Vitamin K has a delayed onset of action due to its need to stimulate the synthesis of clotting factors so its effects begin as the effects of 4FPCC diminish. 4FPCC is the standard of care treatment for this clinical population in the Regions Hospital Emergency Department. | 0 | 34 | EG000 |
| Group 2 | Variable Dose 4FPCC | The FDA-approved variable dosing algorithm is as follows:~initial INR 2-3.9: 25 IU/kg (maximum dose 2500 IU), initial INR 4-6: 35 IU/kg (maximum dose 3500 IU), and initial INR \>6: 50 IU/kg (maximum dose 5000 IU). The patient weight will be obtained using a scale and documented by the treating registered nurse~4-factor prothrombin complex concentrate (4FPCC): 4-factor prothrombin complex concentrate (4FPCC) contains all of the vitamin K-dependent clotting factors inhibited by warfarin, making it desirable for use in warfarin reversal for emergent bleeds. Multiple guidelines currently recommend 4FPCC for warfarin reversal in vitamin K-dependent major bleeding or intracranial hemorrhage. 4FPCC has a fast onset of action and has demonstrated significant reversal of INR within 10 minutes.
