Review Question - QID 210474

A 24-year-old man with epilepsy refractory to valproic acid, phenytoin, and levetiracetam undergoes magnetic resonance imaging of his brain while monitored by anesthetic care. He wakes up screaming in pain due to an electrocardiogram lead having caused a significant thermal burn circumferentially around his left leg. He is admitted to the medical intensive care unit for continuous electroencephalogram monitoring while on a midazolam infusion for seizure suppression and supportive care for his burn. Overnight, the nurse continued to increase the patient's midazolam infusion rate, but she also noticed that his left toes were cold to the touch with significant edema. His temperature is now 100°F (37.8°C), blood pressure is 110/75 mmHg, pulse is 80/min, respirations are 10/min and oxygen saturation is 95% on 2 liters nasal cannula. No dorsalis pedis or posterior tibial pulses are detected on the left lower extremity. A delta pressure of 25 mmHg is obtained in the left leg. What is the most appropriate next step in management?
