First Things First (assess & treat for the following)
First Things First (assess & treat for the following)
- Is extremity irreversible, threatened or viable?
- Irreversible
- Cyanotic/blue
- Absent capillary refill
- Mottled/marbled
- Anesthesia/insensate
- No motor function
- No arterial or venous Doppler signals in foot
- Threatened: treat w/ sense of urgency
- Waxy/white color
- Slow capillary refill
- Moderate to severe pain
- Mildly decreased sensory & motor function
- Absent arterial Doppler signals in foot
- Venous Doppler signals present in foot
- Viable
- Pale/pallor
- Normal or mildly slowed capillary refill
- Cool
- Minimal or no pain
- Normal sensory & motor function
- Is there a palpable pulse or Doppler signal or absent Doppler signals?
- Palpate pulses in the dorsalis pedis (mid-dorsal foot) & posterior tibial (posterior to medial malleolus) positions.
- If nonpalpable, interrogate for Doppler signals w/ a continuous wave Doppler.
- Definitions
- Claudication: pain, usually in the calf or calves w/ exertion (subsides w/ rest)
- Rest pain: pain at rest, usually at night & usually over the metatarsal heads or distal foot
- Tissue loss/gangrene: usually develops in the distal watershed areas or in the immediate site of traumatic injury
