3 major general causes of hypotension post surgery
hypovolaemia
MI/CCF
epidural - peripheral vasodilation
epitheliazation of wounds occurs within
24-48 hours (why we don’t take the dressing off to take a look within the first 2 days- leave to heal)
benefit of negative pressure wound therapy
promotes angiogenesis
which proximal arteries predominantly make the deep and superficial arteries of the hand
deep - radial
superficial - ulnar

GORD
difference between graft and flap
- graft = transferred tissue dependent on RECIPIENT SITE
- flap = transferred tissue INDEPENDENT of recipient site
