monitor
gentle mouth opening exercise

Question 8

when do you want an INR check

Answer 8

within 24hrs prior to surgery

Question 13

why would immediate post op bleeding occur

Answer 13

reactionary/rebound
vessels open up/vasoconstricting LA wears off, sutures loose or lost, patient traumatises socket

Answer 15

pressure with damp gauze
sutures
LA with adrenaline
diathermy

pressure
LA on swab
haemostatic agents
blunt instrument
bone wax
pack and suture

Question 17

what are the haemostatic agents

Answer 17

adrenaline containing LA
cellulose - surgicel
haemocollagen sponge

anti fibrinolysis - tranexamic acid
missing blood clotting factors
plasma or whole blood
desmopressin

Question 19

Answer 19

put pressure
calm patient
clean patient
take history
suction
remove clot
identify where bleeding from

Question 20

contusion of nerve/continuity of epineural sheath and axons maintained

Question 29

what is axonotmesis

Answer 29

continuity of axons but not epineural sheath disrupted
