MSFinals-6033

A 65-year-old woman is admitted with an unstable open tib-fib fracture after a road traffic collision. There is neurovascular compromise; however, there is no overt bleeding, and the decision is made to bleep the on-call consultants in vascular and trauma and orthopaedics to take the patient to theatre. She is on warfarin for atrial fibrillation (AF), and her international normalised ratio (INR) is currently 3.2 (normal value <1.1).
What is the most appropriate intervention before surgery, with regard to her INR?
