A 60 year old male is scheduled for emergency exploration of a AV fistula blow out at his left wrist. Bleeding has been arrested with a compression bandage
He is currently drowsy, arousable and disoriented
His BP is 170 / 100
His CVS and RS examination reveals nothing of significance
ECG shows LVH with strain
CXR - mild cardiomegaly
His HB is 8.5

BT/ CT has not been done

The surgeons want to explore the site at the wrist and will use a tourniquet

Am i justified in using a regional block or is GA the way to go
