Answer

Mottling with concerns for Acute Limb Ischemia

 

Key Points:

• Assess appearance, temperature, sensation, strength and pulses
• Remember 6 P's (paresthesia, pain, pallor, pulselessness, poikilothermia, paralysis)
• Irreversible tissue necrosis can occur by 6 hours from onset
• Start IV Heparin bolus (100 units/kg or 5000u) and continuous IV infusion (1000 units/hr) with considerations for any contraindications
• Immediate vascular consult
