What does the pre-op assessment consist of?
Medical history. Medication history. Blood tests - eGFR, Hb. Weight - dosing. BP measured. BG/HbA1c measured. MRSA screen and eradication.
What problems are there WRT the surgical pathway?
Pre-op nurses often used Pts handwritten list of medication - No Medicines Reconciliation.
No Drs in admission suite to prescribe regular medicine.
Surgeons/ aneasthetists do not have time to do this.

If a pt taking warfarin needs emergency surgery what can be done?
Vit K given = reversal within 4 - 24 hours.
Beriplex = reversal with one hour.
What is beriplex?
Dried prothrombin complex containing variable amounts of some of the clotting factors.
The risk of VTE would be ____ in a patient with AF + CHADVASc = 0 - 2 w/ no prior history of stroke/TIA.
LOW - no LWMH pre surgery required.
The risk of VTE in someone with a history of a single VTE >12 months previously would be:
Low risk - no LWMH needed.
The risk of VTE in someone with AF and CHADSVASc = 3-4 would be
Moderate, start therapeutic dose of LWMH two days after stopping warfarin.
Also: active cancer, recurrent VTE, VTE in past 3-12 months.
The VTE risk in someone with AF CHADVASc score of 5-6:
High, LMWH as above or admit for unfractionated heparin infusion once INR less than 2 or 3.
