Q

CRITICAL LIMB ISCHEMIA- 6 symptoms/ things to know

A
  1. Dry gangrene- black toe, mummified
  2. Wet gangrene- oozy, can get septic
  3. patients with rest pain- patient lay flat and have pain in distal part of foot, when they walk it improves- “sleep in recliner”
  4. 5 P’s- pulselessness, paresthesia, paralysis, pain, pallor
  5. patients with rest pain require urgent revascularization as well as tissue debridement
  6. may result in amputation
