Haemostasis

Rule out any coagulation disorders prior to surgery – or medication that affects coagulation.

Elevation of limb prior to procedure for 3 mins  reduces blood.
Exsanguination via pressure bandage further reduces blood in limb

Tourniquet

Thigh tourniquet – pressure should be 200mgHg over systolic pressure

Adrenaline  vasoconstriction and increase duration of local anaesthetic. Needs to be used with caution in digits.

Ligation of any vessel that is bleeding

Post operative bleeding – use eg calcium alginate sponges

Contraindications for use of tourniquet:
• sickle cell disease
• previous vascular bypass surgery

Complications of tourniquet use:
• tissue necrosis
• inflammation
• paralysis
• thrombosis
